Genus Ptilothyris Walsingham, 1891 Type species: Ptilothyris purpurea Walsingham, 1897. Type locality: Nigeria. The genus Ptilothyris is also an Afrotropical genus, comprising about 20 species in the region (De Prins & De Prins 2020). The genus is superficially similar to Thubdora Park, 2018 in the wing venation, but it can be distinguished by the forewing more elongated and the antenna strongly bipectinate, usually dark brown, more or less flattened in basal half or longer, then creamy white beyond. The male genitalia can also be distinguished from those of Thubdora by the uncus broadly developed, as wide as the basal plate of gnathos, fan-shaped; the gnathos with broad basal plate, usually trifurcate caudally with semi-ovate median lobe and similar sized lateral lobes; the juxta forming double plates, long ventral plate and dorsal plate; and the female genitalia with a hood-shaped signum., Published as part of Park, Kyu-Tek & Karisch, Timm, 2021, The family Lecithoceridae (Lepidoptera, Gelechioidea) from Bioko Island (Equatorial Guinea), with descriptions of five new species, pp. 581-593 in Zootaxa 4995 (3) on page 588, DOI: 10.11646/zootaxa.4995.3.12, http://zenodo.org/record/5057115, {"references":["Walsingham, T.

CIS-7113, CO1 barcode CBNU078, in NHMO. Diagnosis. This new species is similar to P. nausicaa Meyrick, 1926 in the forewing pattern with pale-orange to lightyellow blotch, but it can be distinguished from the latter by the forewing being more elongated, and having a larger, elongate-quadrate yellowish patch, whereas the patch in the forewing is much shorter and more or less ovate in P. nausicaa. Description. Male (Figs. 3 A���C). Wingspan 18.0���19.0 mm. Head: Dark purplish brown dorsal surface; yellowish orange on face. Antenna (Fig. 3B) slightly shorter than forewing; basal segment rather short, slightly dilated toward apex, dark purplish brown dorsally, pale orange ventrally; flagellum weakly bipectinate, with fine whitish cilia, dark purplish brown in basal 1/5 and pale orange in distal 4/5. Second segment of labial palpus (Fig. 3C) thickened, pale orange all around with dark-brown scales at base; 3 rd segment slender, strongly upturned, as long as 2 nd segment, pale orange on lateral surfaces, blackish ventrally. Thorax: Thorax and tegula dark purplish brown ventrally. Forewing ground color purplish brown, irregularly scattered with dark-brown scales in distal part; antemedian fascia dark brown, broad, banded, from 1/3 of costa to 1/3 of inner margin; large, quadrate light yellow patch well-developed beyond antemedian fascia; costa nearly straight; apex obtuse; termen slightly oblique; fringe purplish brown; venation with R 3 and R 4 stalked, R 5 absent; M 1 remote from R 3+4 at base; M 2 present; M 3, CuA 1 and CuA 2 on a common stalk. Hind wing purplish brown, with long, more or less crescent yellowish white streak from base to 3/5 along costa; venation with M 2 absent; M 3 and CuA 1 short stalked. Fore tibia pale orange ventrally; mid tibia dark brown ventrally, tarsi pale orange; hind tibia purplish brown on outer surface with pale orange median band and apex, pale orange on inner surface; tarsi pale orange throughout. Abdomen (Fig. 3H): abdominal segment VIII with heavily sclerotized, C-shaped sclerite dorso-posteriorly. Male genitalia (Figs. 3 D���G): Uncus bifurcated, with broad latero-caudal lobes which are rounded apically, deeply emarginated in U-shape on caudal margin medially. Basal plate of gnathos broad, with semi-ovate expansion in middle on caudal margin; median process rather small, strongly bent from beyond 2/3. Valva elongated, nearly parallel-sided from base to distal end, with rounded apical margin; costal margin slightly concave, with weakly sclerotized marginal band; cucullus not defined from the basal part of valva, slightly upturned, densely setose. Tegumen narrowed distally, with converted V-shaped incision on anterior margin. Juxta broad, with large, membranous median plate, narrowly terminated, with pointed apex. Vinculum weakly sclerotized, banded. Aedeagus slender, bent near basal 1/3, as long as valva; cornuti consisting of a long, sclerotized bar, about 1/3 to 1/2 the length of aedeagus; the bar is located in a long sac of which the distal part is sclerotized into a triangular sclerite near apex. Distribution. Uganda (Kabale and Kabarole Districts). Etymology. This species��� name is derived from Greek, galbus (= yellow) and plat (= flat), referring to the yellowish orange patch on the forewing. Remarks. The flagellum in the antenna of the paratype is differently dark purplish brown in its basal 2/3. It is considered that the different color on dorsal surface probably is caused by lost scales, or it may be due to dimorphism in the species.

Ptilothyris leifaarviki is distinguished from its allies by the forewing with two orange white or white, elongated patches before and after antemedian fascia on inner margin, and M 1 stalked with R 3+4. However, the patches are sometimes not present. The male genitalia are similar to those of P. crassiella, but can be distinguished by the uncus convex on caudal margin or slightly truncated in median part of caudal margin; caudal processes of juxta similarly rounded apically, but left one much shorter; and the phallus strongly bent in basal 1/4, with more spines in spiny plate. It is also differentiated from P. crassiella by the COI barcode sequence. Description. Male and female (Figs. 14 A���D). Forewing length 10.5���11.5 mm. Head: Dark purple dorsally, with erect pale orange scales laterally. Antenna, in male, strongly bipectinate, dark purple and more or less thickened in about basal 2/5, then white in distal part; in female, serrate, dark brown dorsally in about basal half, then white. Labial palpus second segment more or less flattened and thickened, sabershaped, pale orange speckled with greyish scales on outer surface, orange white on inner surface, with black scales dorsally; 3 rd segment shorter than 2 nd segment, pale orange, densely mixed with black scales on outer surface. Thorax: Forewing dark purple, usually with a lengthy, orange-white or white patch along dorsum; patch broken into two by the median fascia (Fig. 14B), patch sometimes absent (Fig. 14C); antemedian fascia metallic brown or dark brown; postmedian fascia inconspicuous, not clearly developed; costa slightly convex in basal 1/3, then straight medially, slightly arched in apical 2/5; apex obtuse; termen nearly vertical; fringe with orange-white basal line; venation (Fig. 14D) differentiated from those of the preceding new species, by having M 1 stalked with R 3+4 for basal 1/6; cell about 3/5 the length of wing, weakly closed. Hind wing much broader than forewing; ground color pale brownish grey with more or less arched inner margin; cell about 3/5 the length of wing, weakly closed; apex obtuse; termen oblique; venation with Rs and M 1 stalked for basal 2/5; M 2 absent, M 3 and CuA 1 short-stalked; 1A+2A forked in basal 1/4; cell closed. Abdomen: Orange white throughout on ventral surface with caudal tuft greyish; a pair of hair-pencils welldeveloped (Fig. 14I). Male genitalia (Figs. 14 E���H) with uncus broadened distally, with truncate median part on caudal margin. Basal plate of gnathos with median lobe longer than lateral lobes; median process relatively small, strongly curved downward beyond middle and recurved. Tegumen weakly sclerotized, with caret-shaped anterior margin. Valva elongate; costa slightly expanded in basal 1/3; cucullus elongate, upturned, with round apex, with long, hair-like scales around ventro-proximal margin. Ventral plate of juxta with short, semi-ovate, latero-caudal lobes, concave medially between lobes on caudal margin. Vinculum banded, narrow, heavily sclerotized. Phallus much shorter than valva, bent at 1/4 to 1/3 on ventral margin, with a lot of minute spinules scattered beyond middle, denser near apex; cornuti with a conical spine apically, and a bundle of spines near middle, about 1/4 the length of phallus. Female genitalia (Figs. 14J, K) with abdominal sternite deeply emarginated medially. Ostium bursae slightly emarginate. Apophyses anteriores relatively short. Antrum divided into two parts, separated by slight constriction; posterior part cup-shaped, with dense spinules; anterior part slightly narrowed toward the junction with corpus bursae, with deep emargination anteriorly. Ductus bursae abruptly broadened at junction, short, about 1/4 the length of corpus bursae. Corpus bursae large, ovate; signum divided by a sclerotized transversal ridge medially; upper part hood-shaped; lower part D-shaped, roughly indented along anterior margin. Distribution. Uganda. Etymology. This species name is in honor of Leif Aarvik, Zoological Museum, University of Oslo, Norway, who collected the holotype. Remarks. One male (gen. slide no. CIS-7076) paratype and one female paratype lack the orange-white patch along the inner margin of the forewing, but their COI barcode sequences are consistent with that of the holotype. It is considered to be an infraspecific variation., Published as part of Park, Kyu-Tek, Mey, Wolfram, Koo, Jun-Mo, Prins, Jurate De & Cho, Soowon, 2019, Revision of the genus Ptilothyris Walsingham, 1897 (Lepidoptera: Gelechioidea: Lecithoceridae), with descriptions of eight new species from Africa, pp. 201-235 in Zootaxa 4567 (2) on pages 223-224, DOI: 10.11646/zootaxa.4567.2.1, http://zenodo.org/record/2594859

Genus Ptilothyris Walsingham, 1897 Transactions of the Entomological Society of London, 1897: 37. Type species: Ptilothyris purpurea Walsingham, 1897. Type locality (TL): Nigeria. [NHMUK] The type species, P. purpurea Walsingham was described on the basis of three syntype specimens: two males collected from Lagos, Nigeria (leg. G. Carter) and a female collected from Kangw��, Ogow�� River, French Congo [present day Gabon] (leg. A. C. Good); a male, designated as the lectotype here, and a female are deposited in NHMUK, and the other male is in CMP. Diagnostic characteristics of the genus are as follows: Antenna shorter than forewing; strongly bipectinate; basal half or slightly longer usually dark brown and more thickened, the rest white and slightly serrate in male, but brown and serrate in female. Forewing ground color dark purple, with broad blackish antemedian fascia bearing some erect scales and postmedian fascia usually indistinct; venation with R 3 and R 4 stalked, R 5 absent; M 2 present, M 3, CuA 1 and CuA 2 on common stalk. Hind wing usually having a semi-transparent, yellowish white patch beneath costal margin and with a tuft of grayish hair-scales at base of vein 1A+2A in male, but those absent in female; venation with M 2 absent��� Walsingham (1897) stated that R 3 is absent, and R 4 and R 5 are stalked in forewing, but it might be due to a misreading R 3 as R 4. All the new species described herein do not have M 2 in hind wing. Abdomen usually dark brown dorsally, with sometimes pale-orange anal tuft, and with a pair of long hairpencils dorso-laterally along anterior margin of the segment VIII; male genitalia with uncus broadened, fanshaped; gnathos with basal plate trifurcate posteriorly; juxta consisting of double plates, ventral plate with welldeveloped caudal process, dorsal plate usually short with triangular processes laterally; and female genitalia with corpus bursae usually having a hood-shaped signum. The genus is superficially similar to Thubdora Park, 2018 in wing venation, but it can be distinguished by the forewing more elongated and the antenna strongly bipectinate, usually dark brown dorsally and more or less flattened in basal half or longer, then white beyond. The male genitalia can also be distinguished from those of Thubdora by the following characters: (i) uncus broadly developed, as wide as the basal plate of gnathos, fanshaped; (ii) gnathos with broad basal plate, usually trifurcate caudally with semi-ovate median lobe and similar sized lateral lobes, rarely with convex caudal margin; (iii) juxta forming double plates, long ventral plate and dorsal plate; (iv) female genitalia with a hood-shaped signum., Published as part of Park, Kyu-Tek, Mey, Wolfram, Koo, Jun-Mo, Prins, Jurate De & Cho, Soowon, 2019, Revision of the genus Ptilothyris Walsingham, 1897 (Lepidoptera: Gelechioidea: Lecithoceridae), with descriptions of eight new species from Africa, pp. 201-235 in Zootaxa 4567 (2) on page 205, DOI: 10.11646/zootaxa.4567.2.1, http://zenodo.org/record/2594859, {"references":["Walsingham, T.

16. Ptilothyris nausicaa Meyrick, 1926 (Fig. 18F) Ptilothyris nausicaa Meyrick, 1926: 288. TL: Congo Belg. [NHMUK]. Diagnosis. Male (Fig. 18F). Ptilothyris nausicaa is superficially similar to the Thubdora species in having less elongate forewing with rounded outer margin. On the other hand, the antenna of this species is dark purple basally and matches well with Ptilothyris. The antennae of the holotype are both broken beyond middle, but, according to the original description, the apical third is white. Material examined. [NHMUK]: 1♂ (holotype), Marungu Plateau, Belg. Congo, TAB Yood, 2. 22., Ptilothyris nausicaa Meyr. E, Meyrick det. In Meyrick Coll., nausicaa Meyr., Meyrick coll., B.M. 1988-290���. Remarks. The species was described based on a single male. While it is currently placed in Ptilothyris, genital examination of this specimen is needed to clearly define its generic position. Distribtion.

12. Ptilothyris subcucullata Park, sp. nov. (Figs. 15 A���E) Type specimen. Holotype: female, Cameroon, Eufelen, H.L. Weber, Acc. 6257, 6 Jan. 1919, gen slide no. CIS- 6849. The holotype is deposited in CMP. Diagnosis. The female genitalia of P. subcucullata are similar to those of P. drepanodes, sp. nov. and P. crassiella, sp. nov., with a similar signum, but P. subcucullata can be distinguished from those species by the caudal margin of the abdominal segment VIII, which is incised medially with a V-shaped emargination, compared to the deeply emarginated into a U-shape in the latter two species, and by the large, heavily sclerotized plate in the posterior of ductus bursae. This new species can be distinguished from other morphologically similar species known only from males as follows: 1) from P. pilosa sp. nov. and P. hylodes sp. nov. by the transversely elongated antemedian fascia on the forewing; and 2) from P. vokaensis sp. nov. by the absence of a white hyaline patch on the hind wing. Description. Female (Figs. 15 A���C). Forewing length 10.0 mm. Head: Vertex purplish dark fuscous; greyish orange erect scales laterally, arising from upper margin of compound eye. Antenna (Fig. 15C) shorter than forewing, biserrate, purplish dark fuscous for basal ��, orange white for the rest, with black spot at apex. Second segment of labial palpus thickened, brownish orange intermixed with dark fuscous scales on dorsal and outer surface, with pale greyish orange apex, pale orange on inner surface; 3 rd segment slender, as long as 2 nd segment, nearly right angle to second segment, orange white dorsally, dark brown ventrally. Thorax: Notum and tegula purplish dark fuscous. Forewing purplish fuscous, with dark-brown scales scattered for apical 1/3; costa nearly straight, arched in apical ��; apex obtuse; termen slightly oblique; fringe concolorous, with narrow indistinct orange-white basal line; venation with M 1 free. Hind wing similar to Ptilothyris leifaarviki sp. nov. Abdomen: Female genitalia (Figs. 15D, E) with abdominal sternite VIII deeply emarginated medially. Ostium bursae more narrowly emarginated, extending past middle of antrum. Apophyses anteriores broken. Antrum large, sclerotized, nearly quadrate. Ductus bursae broadened, longer than corpus bursae, sclerotized in posterior 1/3, with heavily sclerotized, elongate longitudinal plate. Corpus bursae ovate; signum is similar to that of P. leifaarviki. Distribution. Cameroon. Etymology. The specific epithet is derived from the Latin, cucullus (= cap, hood), referring to the hood-shaped signum in the female genitalia., Published as part of Park, Kyu-Tek, Mey, Wolfram, Koo, Jun-Mo, Prins, Jurate De & Cho, Soowon, 2019, Revision of the genus Ptilothyris Walsingham, 1897 (Lepidoptera: Gelechioidea: Lecithoceridae), with descriptions of eight new species from Africa, pp. 201-235 in Zootaxa 4567 (2) on page 224, DOI: 10.11646/zootaxa.4567.2.1, http://zenodo.org/record/2594859

Ptilothyris drepanodes is superficially similar to the preceding new species, but can be distinguished by the absence of the white patch on the hind wing, and the juxta in the male genitalia with near symmetrical, slightly curved caudal processes. Even though apparent variations are found in the shape of juxta among specimens (see Figs. 11F, 11J, and 11H) and in the venation of the forewing between the wing slides no. 7028 and no. 7117, with M 1 nearly connate with R 3+4 or M 1 remote from R 3+4 at base, the COI barcode sequences obtained from several specimens are all identical or nearly identical, strongly suggesting that these are conspecific even with notable infraspecific morphological variations. Description. Male and female (Figs. 11 A-E): Forewing length 10.0– 11.5 mm. Head: Vertex covered with blackish scales; pale orange erect scales laterally arising from upper margin of compound eye. Antenna of male (Fig. 11B, C) with basal segment slender, dark fuscous dorsally, pale orange ventrally; flagellum bipectinate, dark purple in basal 3/5, creamy white beyond with gradually shortened flagellomeral branches; each branch somewhat clavate with cilia on both sides and tip; female antenna slightly serrate. Labial palpus (Fig. 11D) with second segment thickened, pale orange on outer surface, sparsely speckled with dark-fuscous scales; 3 rd segment as long as 2 nd segment, pale orange on inner surface, speckled with darker fuscous scales on outer surface. Thorax: Notum and tegula purplish dark fuscous dorsally. Hind tibia dark fuscous with pale orange band near middle on dorsal surface; apex pale orange. Forewing elongate, ground color dark purple, with broad, black antemedian fascia in basal 2/5 and postmedian fascia just outside the cell; costa slightly expanded anteriorly along basal 1/4, and slightly arched in distal 2/5; apex obtuse; termen oblique; cell weakly closed; venation with R 1 arising just before middle of discal cell; venation (Fig. 11E) with R 3 and R 4 stalked for about basal 1/4, R 4 to costa near apex; R 5 absent; M 1 close to R 3+4 at base (in the wing slide no. CIS-7117) or connate (in wing slide no. CIS- 7028); M 2 arising from lower corner of cell; M 3, CuA 1 and CuA 2 on a common stalk; CuA 1 and CuA 2 stalked for basal 1/4; 1A+2A narrowly forked about basal 1/4; cell about 3/5 the length of wing; cell closed. Hind wing much broader than forewing; ground color same as that of forewing; apex obtuse; termen slightly concave medially; cell short, weakly closed before middle of the wing; venation with Rs and M 1 short-stalked; M 2 absent; M 3 and CuA 1 short-stalked; 1A+2A forked at base; cell short, weakly closed. Abdomen (Fig. 11L): Spinous zones on tergites; pale orange on ventral surface throughout; a pair of long hairpencils laterally along the anterior margin of segment VIII, about twice the length of segment VII; sternite VIII with strongly arched sclerite along anterior margin. Male genitalia (Figs. 11 F–K) with uncus broadly expanded distally; caudal margin slightly emarginate medially. Median lobe of basal plate of gnathos relatively long, subovate, with lateral lobes produced apically. Valva elongate; costa nearly straight basally, strongly upturned beyond middle, with nearly straight margin; cucullus narrowed toward rounded apex, with long hair-like scales around ventro-proximal margin. Juxta bifurcate, with sickle-shaped, nearly symmetrical caudal processes; caudal processes about 1/3 the length of juxta, directed sideward apically, small ovate process on anterior margin; dorsal plate with concave dorsal margin and slightly arched anterior margin. Vinculum narrow, band-like, heavily sclerotized. Phallus slender, shorter than valva; cornuti consisting of a small spine near apex and a line bearing numerous minute spines in distal part. Female genitalia (Figs. 11M, N) with abdominal sternite VIII emarginated in U-shape medially. Ostium bursae similarly emarginated. Apophyses anteriores shorter than half of apophyses posteriores Antrum large, cup-shaped, sclerotized in posterior half, then narrowed, membraneous anteriorly. Ductus bursae broadened posteriorly, bearing a large, longitudinal plate; plate as long as half of ductus bursae. Corpus bursae ovate; signum large, somewhat trapezoidal. Distribution. Uganda. Etymology. The species epithet is derived from the Greek, drepane (= sickle), referring to the sickle-shaped caudal processes of the juxta.

Adult (Figs. 7 A���C). Forewing length 9���10 mm. Ptilothyris serangota is superficially similar to the type species, P. purpurea, in pattern, but it can be distinguished from the latter by the white hyaline patch on the hind wing, which is extended longitudinally from near base to near apex. Male abdomen (Fig. 7I) has spinous zones on tergites; with a pair of long hair-pencils along the anterior margin of segment VIII, twice longer than length of segment VII. Female abdomen is not modified as above. Male genitalia (Figs. 7 D���H). Uncus broadened distally, fan-shaped, slightly emarginated mesially along caudal margin. Basal plate of gnathos trifurcate; median lobe semi-ovate, slightly longer than the lateral lobes, and often exceeding caudal margin of uncus; lateral lobes heavily sclerotized, curved mesiad; median process strongly curved beyond middle, acute at apex. Valva elongate nearly parallel-sided basally; costa slightly expanded near base, concave medially; cucullus elongate, produced apically, subtriangular, with dense setae along lower margin. Dorso-caudal processes of juxta asymmetrical, left one short, triangular; right one long, sickle-shaped, slightly curved inwardly; with a minute triangular process on left lateral margin and a well-developed ventral process on right lateral margin near base. Vinculum band-like, well sclerotized. Phallus very slender, narrowed apically, about the same length of valva; cornutus absent (Figs. 7E, H). Material examined.

In the collection of RMCA, a male specimen labeled as ��� TYPE ��� determined as caerulea Ghesqui��re, 1940 is deposited. We are sure that the name of ��� Ptilothyris serangota Meyr. ab. caerulea Ghes., 1940��� was erroneously written by Ghesqui��re. The name caerulea Ghesqui��re on the label is probably a name erroneously written, instead of cyanea Ghes. in the publication. This is probably the same kind of mistakes by Ghesqui��re, 1940 as noted in P. porphyrea . The name, cyanea Ghes., is synonymized with P. serangota Meyrick herein. The right caudal projection of an additional specimen (Figs. 7F, G) is shorter than that of the type, but it is considered as an infraspecific variation., Published as part of Park, Kyu-Tek, Mey, Wolfram, Koo, Jun-Mo, Prins, Jurate De & Cho, Soowon, 2019, Revision of the genus Ptilothyris Walsingham, 1897 (Lepidoptera: Gelechioidea: Lecithoceridae), with descriptions of eight new species from Africa, pp. 201-235 in Zootaxa 4567 (2) on page 212, DOI: 10.11646/zootaxa.4567.2.1, http://zenodo.org/record/2594859

9. Ptilothyris hylodes Park, sp. nov. (Figs. 12 A–G) Type specimen. Holotype: male, Uganda, Kibale Nat. Park, Biol. Field Station, 19–24 xi 2014, LF leg. W. Mey, gen slide no. CIS-7003, COI barcode CBNU-029. The type is deposited in MfN. Diagnosis. Ptilothyris hylodes is also superficially similar to P. drepanodes sp. nov. by the absence of orange white patch on the hind wing, but it is differentiated by the shape of caudal lobes of juxta. It can also be distinguished from the following species, P. crassiella sp. nov. by the pale yellow flagellum in basal part. The male genitalia are similar to those of vokaensis sp. nov., but can be distinguished by the basal plate of gnathos with narrow, rather slender median lobe; cucullus more sharply produced apically, with nearly straight costal margin; phallus with a pair of minute spines apically, whereas the spines are absent in P. vokaensis; and the hair-pencils much shorter. The COI barcode sequences revealed that they are different. Description. Male (Figs. 12 A–C). Forewing length 9.0 mm. Head: Dark brown dorsally, with pale yellow erect scales laterally, arising from upper margin of compound eye. Antenna (Fig. 12B) basal segment slender, dark fuscous dorsally, pale yellow ventro-laterally; flagellum bipectinate, each subsegment with whorled scales and long cilia, pale yellow speckled with blackish scales in basal half and pale yellow beyond. Labial palpus (Fig. 12C) with 2 nd segment thickened, rather flattened, saber-shaped, pale yellow, speckled with dark brown scales on outer surface; 3 rd segment as long as 2 nd segment, same color as the second ventro-laterally, pale yellow on inner surface. Thorax: Notum and tegula dark brown dorsally. Hind tibia dark fuscous in basal 1/4 and in apical 1/4, pale yellow near middle. Forewing ground color dark brown; costa slightly expanded anteriorly in basal 1/3, then nearly straight, arched in apical 1/4; apex obtuse; hind wing much broader than forewing. Abdomen (Fig. 12G): Spinous zones on tergites; a pair of hair-pencil on anterior margin of segment VIII laterally, relatively short, slightly longer than the length of segment VII (Fig. 12 G- ®). Male genitalia (Figs. 12 D–F) with uncus with gently arched caudal margin. Median lobe of basal plate of gnathos slender, much longer than lateral lobes caudally (Fig. 12 F-©); lateral lobes broadly rounded apically. Valva elongate; cucullus with more or less rounded apex, costal margin nearly straight. Ventral plate of juxta with oblique caudal margin; caudal margin slightly concave medially; caudal process not distinctly produced, with obtuse left angle and acute right angle. Vinculum narrow, band-like, heavily sclerotized. Phallus more or less slender, much shorter than valva, minute spinules densely scattered beyond middle; cornuti with a pair of small spines apically, and a bundle of spines well developed near middle. Distribution. Uganda. Etymology. The species epithet is derived from the Greek, hyle (= forest) with – odes, a Greek suffix denoting resemblance.

1. Ptilothyris purpurea Walsingham, 1897 (Figs. 3 A���D, Figs. 4 A���H) Ptilothyris purpurea Walsingham, 1897: 38. TL: Lagos, Nigeria. [NHMUK] Diagnosis. Adult (Figs. 3 A���D). Forewing length 11.0���12.0 mm. The common diagnostic characteristic characters of P. pupurea include: (i) antenna strongly bipectinate, dark brown in the basal 3/5, orange white beyond in the male; serrate, dark brown in basal 3/ 4 in the female; (ii) forewing elongate, with the length more than 4 times the width, and the ground color dark brown with purplish iridescence. The species is similar to P. vokaensis sp. nov. and P. porphyrea Ghesqui��re in having orange-white patch on hind wing in the male. However, it can be easily distinguished from P. vokaensis sp. nov. by the antemedian fascia on the forewing which is broader, irregularly shaped, more strongly convex outwardly, while in P. vokaensis the patch is nearly parallel sided, vertically elongated, not reaching inner margin. The hyaline patch on the hind wing is more or less semiovate, whereas it is nearly quadrate in P. vokaensis. Ptilothyris purpurea can also be distinguished from P. porphyrea by the dark-brown fringe along the inner margin of the hind wing, whereas the fringe in P. porphyrea is light orange from basal 1/4 on inner margin to near tornus. The abdomen of male (Fig. 4H) has spinous zones on tergites, with a pair of long hair-pencils on anterior margin of abdominal segment VIII; sternite VIII with strongly arched linear sclerotization along anterior margin and tergite VIII with narrow quadrate plate bearing laterally narrow sclerites. The male genitalia of P. purpurea provide a more easily distinguishable character from those of P. vokaensis and P. porphyrea by having the juxta with large, slender, horn-shaped caudal processes. Male genitalia (Figs. 4 A���D). Uncus broadened apically, deeply concave medially forming two rounded lobes. Basal plate of gnathos trifurcate apically, median lobe semi-ovate, slender; lateral lobes curved inwardly; median process strongly curved downwards. Valva elongate, slightly expanded along basal 1/3 of costa; cucullus strongly upturned, gradually narrowing to a rounded apex, densely setose, with long hairs around ventro-proximal margin. Ventral plate of juxta with two symmetrical, slightly curved, sickle-shaped caudal processes, slightly longer than 2/ 5 of length of juxta; dorsal plate short, with nearly straight caudal margin. Phallus shorter than valva, tapered apically; cornutus long, about 3/4 of phallus, heavily sclerotized, sharply acute apically. Female genitalia (Figs. 4 E���G). Abdominal sternite VIII deeply emarginate medially, anterior margin broadly and shallowly concave. Ostium bursae deeply emarginate. Lamella antevaginalis broad, sclerotized, subquadrate. Apophyses anteriores very short; apophyses posteriores also relatively short, about the same length of segment VIII. Antrum short. Ductus bursae slightly longer than corpus bursae, broader in posterior 2/5; base of ductus seminalis broad, arising from near posterior 2/5. Corpus bursae ovate; signum large, half moon-shaped, with a band-like sclerotized ridge along flat side. Material examined.

CIS-7090—deposited in NHMUK. Diagnosis. Ptilothyris crassiella is superficially similar to P. hylodes sp. nov., but it can be distinguished from the latter by the following: antenna dorsally dark brown whereas pale yellow speckled with blackish scales in P. hylodes; in male genitalia, the median lobe of basal plate of gnathos short, rounded caudally, cucullus with concave costa, curved inward apically, whereas the latter with nearly straight costa and somewhat straight outward apically; phallus with a spiny plate-like cornutus near middle, while such a plate absent in P. hylodes. The hair-pencils are longer than those of the latter. It is also differentiated from P. hylodes or P. drepanodes by the COI barcode sequences. Description. Male and female (Figs. 13 A–D). Forewing length 10.0– 11.5 mm. Head: Purplish dark fuscous dorsally, with greyish orange erect scales laterally. Antenna bipectinate, basal half purplish dark fuscous, orange white beyond. Second segment of labial palpus (Fig. 13C) thickened, pale greyish orange, speckled with brown scales on outer surface; 3 rd segment shorter than 2 nd, more or less thickened, same color as 2 nd segment; female antenna slender, slightly serrate. Thorax: Notum and tegula purplish dark fuscous. Forewing dark purple with black antemedian fascia; postmedian fascia inconspicuous; costa nearly straight, arched in apical 1/4; apex obtuse; termen slightly convex; venation (Fig. 13D) with R 1 strongly bent near base, arising before middle of discal cell; R 3 and R 4 stalked in basal 1/8; R 4 reaching costa, close to apex; R 5 absent,; M 1 close to R 3+4 at base; M 2 arising from lower corner of cell; M 3, CuA 1 and CuA 2 on a common stalk, rather evenly spaced; 1A+2A narrowly forked in basal 1/5; cell about 3/5 the length of wing, closed. Hind wing much broader than forewing, brownish grey; apex obtuse; termen oblique, slightly sinuate medially; cell weakly closed before middle of wing; venation with M 1 short-stalked with Rs; M 2 absent; M 3 and CuA 1 short-stalked. Abdomen: Orange white from base to sternite VII on ventral surface, with rough fuscous scales terminally; zones of dense spines well-developed on tergites, with a pair of long hair-pencils laterally on anterior margin of abdominal segment VIII, longer than length of segment VII (Fig. 12H).

Valva elongate; costa with broad expansion in basal 1/3; cucullus elongate, with gently concave costa, narrowed toward apex, with dense hair-like scales on surface, especially around ventro-proximal margin. Ventral plate of juxta with large, thumb-like caudal lobe, right-angled; dorsal plate with broad band centrally. Vinculum banded, less sclerotized medially. Phallus shorter than valva, slightly bent at 1/4–1/3 ventrally, with minute spinules scattered in distal half; cornuti with a row of spines distally, about 1/4 the length of phallus, and a spiny plate near middle. Female genitalia (Figs. 13I, J) with abdominal sternite VIII deeply emarginated in U-shaped medially. Apophyses anteriores thick, about 3/5 the length of apophyses posteriores. Ostium bursae more narrowly emargnated, reaching near middle of lamella antevaginalis. Antrum quadrate, weakly sclerotized. Ductus bursae sclerotized in posterior half, slightly twisted, wrinkled and oblique, then widened and membraneous in anterior half; dusctus seminalis broad, arising from near middle. Corpus bursae elongate, as long as ductus bursae, junction with ductus bursae indistinct; signum large, tilted semicircular in shape. Distribution. Uganda. Etymology. The specific name is derived from the Latin, crassus (= thick, stout), referring to the more or less thick 3 rd segment of the labial palpus.

6. Ptilothyris vokaensis Park, sp. nov. (Figs. 9 A–H) Type specimens. Holotype: male, Congo Republic, Pool Region, Voka 04-405, 14-41E, 620 m, 25–30 May 1993, J. Rawlins, R. Davidson, G. Onore, D. Schlitter, gen. slide no. CIS-5626. Paratype: 1♂, same data as holotype, gen. slide no. CIS-6956. Types are deposited in CMP. Diagnosis. Ptilothyris vokaensis is externally similar to P. purpurea Walsingham and the different characteristics between two species are noted in the diagnosis of P. purpurea. The male genitalia can be distinguished by the juxta with spine-like caudo-lateral processes in P. purpurea, which are absent in P. vokaensis sp. nov. It is also distinguished from P. porphyrea Ghesquière by the hind wing with purplish grey fringe along inner margin throughout; in P. porphyrea, the hind wing has orange fringe medially. The hair-pencil in the abdominal segments between VII and VIII of P. vokaensis is longer than that of P. porphyrea. Description. Male (Figs. 9 A–C). Forewing length 9.5–10.0 mm. Head: Dark purple dorsally, with light-orange, erected scales laterally. Antenna (Fig. 9B) strongly bipectinate with long flagellomeral branches, dark purple in basal 3/5, orange white beyond, with gradually shortened flagellomeral branches. Labial palpus (Fig. 9C) with 2 nd segment thickened, rather flattened, saber-shaped, light orange all around; 3 rd segment slender, as long as the 2 nd segment, speckled with black scales on outer surface; apex acute, black. Thorax: Notum and tegula dark purple. Hind tibia partly descaled, somewhat similar to that of P. pilosa.

Phallus rather slender, slightly arched, narrowed toward apex, slightly shorter than valva; cornutus small, heavily sclerotized, angled near middle, curved upward basally and downward apically, claw-like apically. Distribution. Uganda. Etymology. The species epithet is derived from the Greek, pilos (= hair), referring to hairy cilia of the antenna.

9. Ptilothyris hylodes Park, sp. nov. (Figs. 12 A���G) Type specimen. Holotype: male, Uganda, Kibale Nat. Park, Biol. Field Station, 19���24 xi 2014, LF leg. W. Mey, gen slide no. CIS-7003, COI barcode CBNU-029. The type is deposited in MfN. Diagnosis. Ptilothyris hylodes is also superficially similar to P. drepanodes sp. nov. by the absence of orange white patch on the hind wing, but it is differentiated by the shape of caudal lobes of juxta. It can also be distinguished from the following species, P. crassiella sp. nov. by the pale yellow flagellum in basal part. The male genitalia are similar to those of vokaensis sp. nov., but can be distinguished by the basal plate of gnathos with narrow, rather slender median lobe; cucullus more sharply produced apically, with nearly straight costal margin; phallus with a pair of minute spines apically, whereas the spines are absent in P. vokaensis; and the hair-pencils much shorter. The COI barcode sequences revealed that they are different. Description. Male (Figs. 12 A���C). Forewing length 9.0 mm.

[NHMUK]: 1♀ (holotype), Zambia, N. Rhodesia, Congo-Zambesi watershed, 1918, leg. H. S. Evans, gen. slide no. BM-9135/Clarke. Distribution. Zambia. Remarks. Even though the wing color pattern of this species is exceptionally different from other members of the genus, the female genitalia have a prolonged hood-shaped signum which is a common character of the genus Ptilothyris., Published as part of Park, Kyu-Tek, Mey, Wolfram, Koo, Jun-Mo, Prins, Jurate De & Cho, Soowon, 2019, Revision of the genus Ptilothyris Walsingham, 1897 (Lepidoptera: Gelechioidea: Lecithoceridae), with descriptions of eight new species from Africa, pp. 201-235 in Zootaxa 4567 (2) on page 231, DOI: 10.11646/zootaxa.4567.2.1, http://zenodo.org/record/2594859, {"references":["Clarke, J.

6. Ptilothyris vokaensis Park, sp. nov. (Figs. 9 A���H) Type specimens. Holotype: male, Congo Republic, Pool Region, Voka 04-405, 14-41E, 620 m, 25���30 May 1993, J. Rawlins, R. Davidson, G. Onore, D. Schlitter, gen. slide no. CIS-5626. Paratype: 1♂, same data as holotype, gen. slide no. CIS-6956. Types are deposited in CMP. Diagnosis. Ptilothyris vokaensis is externally similar to P. purpurea Walsingham and the different characteristics between two species are noted in the diagnosis of P. purpurea. The male genitalia can be distinguished by the juxta with spine-like caudo-lateral processes in P. purpurea, which are absent in P. vokaensis sp. nov. It is also distinguished from P. porphyrea Ghesqui��re by the hind wing with purplish grey fringe along inner margin throughout; in P. porphyrea, the hind wing has orange fringe medially. The hair-pencil in the abdominal segments between VII and VIII of P. vokaensis is longer than that of P. porphyrea. Description. Male (Figs. 9 A���C). Forewing length 9.5���10.0 mm. Head: Dark purple dorsally, with light-orange, erected scales laterally. Antenna (Fig. 9B) strongly bipectinate with long flagellomeral branches, dark purple in basal 3/5, orange white beyond, with gradually shortened flagellomeral branches. Labial palpus (Fig. 9C) with 2 nd segment thickened, rather flattened, saber-shaped, light orange all around; 3 rd segment slender, as long as the 2 nd segment, speckled with black scales on outer surface; apex acute, black. Thorax: Notum and tegula dark purple. Hind tibia partly descaled, somewhat similar to that of P. pilosa. Forewing ground color dark purple; antemedian fascia in basal 2/5 distinct, more or less elongate-quadrate; postmedian fascia broadly suffused; costa slightly convex in both basal 1/4 and distal 1/4, otherwise nearly straight medially; apex obtuse; termen slightly oblique; cell closed; venation as in the description for the genus. Hind wing broader than forewing, same ground color as in forewing, with quadrate hylane patch. Abdomen (Fig. 9H): Densely spinous on tergites; with a pair of long hair-pencils along anterior margin of segment VIII, about 1.5 times longer than the length of segment VII (Fig. 9 H-?); sternite VIII with narrow, gently concave, band-like sclerite along anterior margin. Female unknown. Male genitalia (Figs. 9 D���G) with uncus broadened distally, fan-shaped, moderately emarginated at middle on caudal margin, with slightly produced lateral lobes. Gnathos with median lobe semiovate, much longer than lateral ones (Fig. 9 D- ��); median process gently bent near middle and strongly bent downward sub-apically. Valva elongate; costa slightly expanded near base, then slightly concave; cucullus elongate, slightly curved inwards apically. Ventral plate of juxta oblique, slightly concave caudally, with right lobe developed; dorsal plate with triangular plates on anterior margin laterally (Fig. 9G). Vinculum a band, narrow, heavily sclerotized. Phallus slightly shorter than valva, curved near basal 1/3; cornutus with a row of minute spines. Distribution. Congo Republic. Etymology. The species epithet is named after the type locality., Published as part of Park, Kyu-Tek, Mey, Wolfram, Koo, Jun-Mo, Prins, Jurate De & Cho, Soowon, 2019, Revision of the genus Ptilothyris Walsingham, 1897 (Lepidoptera: Gelechioidea: Lecithoceridae), with descriptions of eight new species from Africa, pp. 201-235 in Zootaxa 4567 (2) on pages 215-217, DOI: 10.11646/zootaxa.4567.2.1, http://zenodo.org/record/2594859

12. Ptilothyris subcucullata Park, sp. nov. (Figs. 15 A–E) Type specimen. Holotype: female, Cameroon, Eufelen, H.L. Weber, Acc. 6257, 6 Jan. 1919, gen slide no. CIS- 6849. The holotype is deposited in CMP. Diagnosis. The female genitalia of P. subcucullata are similar to those of P. drepanodes, sp. nov. and P. crassiella, sp. nov., with a similar signum, but P. subcucullata can be distinguished from those species by the caudal margin of the abdominal segment VIII, which is incised medially with a V-shaped emargination, compared to the deeply emarginated into a U-shape in the latter two species, and by the large, heavily sclerotized plate in the posterior of ductus bursae. This new species can be distinguished from other morphologically similar species known only from males as follows: 1) from P. pilosa sp. nov. and P. hylodes sp. nov. by the transversely elongated antemedian fascia on the forewing; and 2) from P. vokaensis sp. nov. by the absence of a white hyaline patch on the hind wing. Description. Female (Figs. 15 A–C). Forewing length 10.0 mm. Head: Vertex purplish dark fuscous; greyish orange erect scales laterally, arising from upper margin of compound eye. Antenna (Fig. 15C) shorter than forewing, biserrate, purplish dark fuscous for basal ¾, orange white for the rest, with black spot at apex. Second segment of labial palpus thickened, brownish orange intermixed with dark fuscous scales on dorsal and outer surface, with pale greyish orange apex, pale orange on inner surface; 3 rd segment slender, as long as 2 nd segment, nearly right angle to second segment, orange white dorsally, dark brown ventrally. Thorax: Notum and tegula purplish dark fuscous. Forewing purplish fuscous, with dark-brown scales scattered for apical 1/3; costa nearly straight, arched in apical ¼; apex obtuse; termen slightly oblique; fringe concolorous, with narrow indistinct orange-white basal line; venation with M 1 free. Hind wing similar to Ptilothyris leifaarviki sp. nov. Abdomen: Female genitalia (Figs. 15D, E) with abdominal sternite VIII deeply emarginated medially. Ostium bursae more narrowly emarginated, extending past middle of antrum. Apophyses anteriores broken. Antrum large, sclerotized, nearly quadrate. Ductus bursae broadened, longer than corpus bursae, sclerotized in posterior 1/3, with heavily sclerotized, elongate longitudinal plate. Corpus bursae ovate; signum is similar to that of P. leifaarviki. Distribution. Cameroon. Etymology. The specific epithet is derived from the Latin, cucullus (= cap, hood), referring to the hood-shaped signum in the female genitalia.

2. Ptilothyris porphyrea Ghesqui��re, 1940 (Figs. 5 A���G) Ptilothyris porphyrea Ghesqui��re, 1940b: 107. TL: DR Congo. [RMCA] Diagnosis. Adult (Fig. 5A, B). Forewing length 10.5���11.5 mm. Ptilothyris porphyrea is similar to P. purpurea Walsingham by having an orange-white hyaline patch on the hind wing, but it can be distinguished by the hind wing with more ovate patch medially and with pale-orange fringe on inner margin from basal 1/3 to near tornus. Male abdomen (Fig. 5G) has spinous zones on tergites, with a pair of shorter hair pencils on anterior margin of segment VIII, and with segment VIII similar to P. purpurea. Female abdomen is not strongly modified as in P. purpurea. The male genitalia provide a more distinct diagnostic character by the juxta, lacking two, symmetrical, long, caudal lobes that are present in P. purpurea. Male genitalia (Figs. 5 C���F). Uncus broadly expanded from base, forming a fan-shaped process, strongly convex along caudal margin. Basal plate of gnathos trifurcate, with elongate median lobe, exceeding caudal margin of uncus; lateral lobes broadly rounded. Valva elongate; costa slightly expanded dorsally near base; cucullus strongly upturned, rounded apically, costal margin slightly concave, with dense hairs around ventro-proximal margin, Ventral plate of juxta elongate-trapezoidal, with shortly produced caudal lobes. Vinculum a narrow bandlike, heavily sclerotized. Phallus slender, slightly shorter than valva, strongly curved along basal 1/3; dorsal margin sharply produced apically; cornuti consisting of a narrow sclerotized spine with a dorsal row of serration, about 1/4 the length of phallus, and a small, short apical spine. Female genitalia (Figs. 5H, I). Abdominal sternite VIII deeply emarginate medially. Ostium bursae deeply emarginate medially. Lamella postvaginalis weakly produced. Apophyses posteriores about 3/4 the length of apophyses anteriores. Antrum weakly sclerotized. Ductus bursae about 1.5 times length of corpus bursae; ductus seminalis arising from middle, as broad as 1/2 the width of anterior part in ductus bursae. Corpus bursae ovate; signum large, prolonged, more sclerotized in posterior half. Material examined.

J. Ghesqui��re, r. DET. F. 4409, gen. slide no. CIS-7093. Distribution. DR Congo. Remarks. The three specimens that were designated as ��� holotype, paratype, and allotype ��� have their labels written as Ptilothyris chalybaea Ghes., 1940. However, it was confirmed that Ghesqui��re himself, or possibly his technician, mislabeled ��� porphyrea Ghes. ��� as chalybaea Ghes., because all the data on the labels of chalybaea Ghes. are exactly written in the same way as those of porphyrea Ghes. in its description. Moreover, no name of chalybaea Ghes. could be found in the NHMUK card index (Lepindex) or any other available references. Ghesqui��re (1940) probably described the species with a different name, porphyrea Ghes., instead of P. chalybaea, the one he originally suggested on the label under the specimen. In the Afromoths (2018), the name of P. porphyrea Ghes. has been used as the valid name, instead of P. chalybaea. After the publication of this revision, the correct labels with the valid name should be placed on the specimens., Published as part of Park, Kyu-Tek, Mey, Wolfram, Koo, Jun-Mo, Prins, Jurate De & Cho, Soowon, 2019, Revision of the genus Ptilothyris Walsingham, 1897 (Lepidoptera: Gelechioidea: Lecithoceridae), with descriptions of eight new species from Africa, pp. 201-235 in Zootaxa 4567 (2) on page 209, DOI: 10.11646/zootaxa.4567.2.1, http://zenodo.org/record/2594859, {"references":["Ghesquiere, J.
