Pachyotoma primamexicana sp. nov, from Popocatépetl, Mexico is described; it is similar to Pachyotoma alpa (Christiansen & Bellinger, 1980) and P. muskegis (Guthrier, 1903). It can be distinguished from all other the members of the genus by the small size of PAO (about half the size of closest eye) and the formula (2,3,3) of the slightly capitate tenent hairs. An identification key for Nearctic Pachyotominae and a table with diagnostic morphological characters to the Nearctic species of the genus with integument clearly granulated is given. Three new records of species from Mexico are listed: Pachyotoma crassicauda (Tullberg, 1871), Coloburella octogenaria (Mills & Schmidt, 1957) and Bonetrura boneti (Yosii, 1962). A discussion on the distribution of the subfamily Pachyotominae and some notes on the biogeography of the subfamily are provided.

The new species was found in litter and moss samples of P. montezumae forest, at an altitude of more than 3,000 m asl. During the extraction there were many specimens (more than 200), including adults and juveniles. Etymology. The new species is named for being the first Mexican species of the genus described from the country (primus = first). Remarks. P. muskegis has few manubrial setae and is about twice the size of P. primamexicana sp. nov. (Table 1). The new species is characterized by the presence of a very small PAO (about half the size of one eye, while in P. mustegis is about the size of short diameter of the eye); of 5 strong setae on distal anterior surface of dens, and 8 thin setae on posterior surface; retinaculum has 4 teeth on each ramus and from 1 to 4 setae on its corpus (P. muskegis has 2 setae); manubrium with many setae (37 pairs) on posterior surface and without setae on anterior surface; ventral tube with 6+6 laterodistal setae and 9 posterior setae, of which 3 are longer. Tibiotarsus P. muskegis has a clear apical subdivision, which is lackining in P. primamexicana sp. nov. It is also similar to P. alpa (Christiansen & Bellinger, 1980) from the USA, but differs in having a smaller PAO, slightly capitate tenent hairs 2, 3, 3 (versus 1, 2, 2 on P. alpa) on tibiotarsi and a higher number of manubrial setae., Published as part of Palacios-Vargas, José G. & Arbea, Javier I., 2022, The subfamily Pachyotominae in Mexico (Collembola: Isotomidae) with description of a new Pachyotoma species, pp. 245-259 in Zootaxa 5194 (2) on pages 247-248, DOI: 10.11646/zootaxa.5194.2.6, http://zenodo.org/record/7147359, {"references":["Christiansen, K.

Type material. Holotype (male) mounted on slide 19-03-2016, Mexico, Veracruz, Estación de Biología Tropical, Los Tuxtlas, sample from soil. 17 paratypes on slide and 20 more on ethanol 70% with the same data. This material is deposited in the Colección de Collembola de México y Ácaros Edáficos, Facultad de Ciencias, Universidad Nacional Autónoma de México, México. Etymology. The species is named in honor of PhD Andy Dorey Ruiz Huerta, who has dedicated her efforts to the study and treatment of respiratory diseases in Mexico, including research on COVID-19, and also, the fiancé of the senior author. The epithet is a noun in the genitive case obtained directly from the modern feminine personal name Andy Dorey according to Art. 31.1.2. of the international code of zoological nomenclature. Remarks. The 11 species of this group are distributed in Africa (6), America (4), and Oceania (1), which denotes mainly a Gondwanan distribution. Most of the representatives of this genus share a common morphological pattern (except Galumnopsis Saggita Balogh, 1970), the reason why they look very similar to each other, and the main features to distinguish the species are the shape of sensillar setae, presence or absence of prodorsal seta, porose area dorsosejugalis, porose area postanalis, position of seta ad 3 in ventral plate and recently we observed that the position of seta h 1 on the notogaster can be a very useful character for species delimitation. This new species shares clavate sensillar setae with another six members but can be distinguished by a special combination of characters. It can be differentiated from G. clavata Mahunka, 1983 by the smooth body surface against foveolated, all notogastric porose areas well defined, the presence of median pore, lyrifissure im anterior to h 3 and not between h 3 and lp, seta h 2 and h 3 near to A1 and seta h 1 above A3; from G. holoscripta Grandjean, 1931 it differs in cheliceral insertion apodeme scar near height of Aa and lm, position of seta h 1 , disposition of genital setae, Aa and A1 vertically aligned, bigger distance between ad 2 and ad 3 in ventral plate, and finally Ap not illustrated or mentioned in G. holoscripta, probably absent; from G. longisetosus Mahunka, 1986 it can be easily distinguished by the short lamellar setae and sensillar setae without minute spicules; from G. ruginervis Balogh, 1962 in having a minute lamellar setae, median pore at height of A1 and position of gla posterior to A1; from G. sellnicki Balogh, 1960 in the presence of lamellar setae, Ap bigger in size, sensillar setae less globular in shape and a curved dorsosejugal suture instead of straight in the later species; finally, it can be distinguished from G. secunda (Sellnick, 1923) in the scar of chelicera insertion posterior to Aa, h1 above A3 and not between them, Ap bigger in size, im far from A1 and the absence of Ad.

Holotype (female) mounted on slide 08–10–2016, Mexico, Veracruz, Estación de Biología Tropical, Los Tuxtlas, sample by canopy fogging. 16 paratypes on slides with same data. This material is deposited in the Colección de Collembola de México y Ácaros Edáficos, Facultad de Ciencias, Universidad Nacional Autónoma de México, México. Etymology. The species rickiglesiasi is named in honor of MSc Ricardo Iglesias Mendoza, who has dedicated many years to studying the oribatid mite fauna of Mexico. The epithet is a compound masculine noun in apposition in the nominative case, obtained by joining the affective nickname “Rick” with which he is known to his students and colleagues, his last name “Iglesias” and the desinence “i” in order to avoid possible confusions according to Art. 31.2.1. and the recommendation 31A of the international code of zoological nomenclature. Remarks. The new species only resembles Notogalumna floridae (Jacot, 1929) from the U.S.A. in having reduced interlamellar setae and a short bothridial seta with blunt apex (obovate head in terms of Jacot (1929)), but can be differentiated by length ratio of lamellar versus rostral setae (the lamellar setae shorter than rostral and in N. floridae the lamellar setae are longer than rostral), porose areas adalares semi rounded instead of triangular shaped, setae lp, h 3 and lyrifissure im anterior to A2 and without an evident projection on the basis of pteromophs. Additionally, the only species registered from Mexico is N. africana from which it differs in lacking a foveolated notogaster, the presence of four pairs of notogastric porose areas instead of three pairs in the latter species, porose areas A1 much smaller and without a boomerang-shape, and by the size of interlamellar and bothridial setae, which are bigger in N. africana., Published as part of Villagomez, Fernando, Palacios-Vargas, José G. & Páez, Jair, 2021, A new species of Notogalumna from the canopy and another new edaphic species of Galumnopsis (Acari: Oribatida: Galumnoidea) from the tropical rainforest of Los Tuxtlas, Mexico, pp. 171-183 in Zootaxa 5020 (1) on pages 172-176, DOI: 10.11646/zootaxa.5020.1.9, http://zenodo.org/record/5223150, {"references":["Jacot, A.

Borgesminthurinus gen. nov. Palacios-Vargas Diagnosis. Body globular, characterized by having thick, relatively long and slightly barbulate setae, very abundant on head and body; with full set of trichobothria present; A, B, C in a triangle on great abdomen and one pair of trichobothria on lesser abdomen (D); no neosminthuroid setae. Setae in large abdomen are thick but short. in singlets. Normal chewing mouth parts. Ant. IV undivided and longer than Ant. III; Ant. III with papilla divided in lobes. Tibiotarsi with 7 tenent hairs on distal whorl; unguis with pseudonychia and no tunica. Sacs of ventral tube smooth; tenacular rami with 3 teeth and basal appendix, corpus tenaculum with 2 setae. Metathoracic legs with trochanteral organ. Dens with ventral chaetotaxy reduced (formula 4, 2 … 1); mucro small, without seta, internal edge crenulate, external smooth. Seta a0 of Abdominal segment VI of females no furcate and no winged setae on lateral anal valves; subanal appendix of female palmate. Type species. Borgesminthururinus andinus gen. nov. sp. nov. Etymology. The new genus is dedicated to Jorge Luis Borges (Buenos Aires, August 24, 1899 ‒‒Geneva, Swit-zerland, June 14, 1986), the Argentinean writer, author of the Manual of Fantastic Zoology, which included spherical animals as Symphypleona are. Remarks. Borgesminthurinus gen. nov. differs from Sminthurinus by having thick and barbulate setae on head and body (versus thin and smooth), there are not neosminthuroid setae on abdomen; setae “a0” on Abd. VI acuminate (always furcated on Sminthurinus) and lacks lateral winged setae on the supranal valve and on each lateral anal valve. Both genera share the presence of Ant. IV undivided, and Ant. III with one papilla; sacs of ventral tube smooth; tenacular rami with 3 teeth and a basal appendix, dens with ventral chaetotaxy reduced and lack of mucronal seta. Most setae are thick and barbulated in the new genus (Table 1). Members of Katianna have 2+2 or 3+3 heavy spines on postocular lobes, and vertex of head with spine-like setae as illustrated by Delamare & Massoud (1963) in Neotropical species and remarked as generic character by Bernard (2014). This genus and the new one lack neosminthuroid seta and seta a0 on Abd. VI is simple, never furcate (Table 1). The head and body chaetotaxy in the new genus are much more abundant than in genera S minthurinus and like Katianna, besides, in these last two genera setae are smooth and thin. Another important difference is that antennal IV of members of Katianna are clearly subdivided and in the new genus is undivided. Vesicephalus Richards, 1964 in Delamare & Massoud (1964) has two vesicles on the head, the antennal segment IV is undivided and antennal segment III has several long and barbulate setae and lacks anterior setae on dens. The new genus lacks the cephalic vesicles, has not long setae on antennal segment III and has several setae on anterior dens.

Pseudanurida sawayai Schuster, 1965, new record to China Examined material: 1 female, China, Hainan Island (western coast), Changjiang County, vicinity of Changhua town, Qizi Bay, 19°21'12"N, 108°40'25"E, flotation of sand samples (Nos. 34, 35 and 38) on beach, 6-IV-2011, Y. Bu, C. W. Huang, M. B. Potapov and N. A. Kuznetsova leg. Remarks. This is the first record for China. Distribution covers the marine littoral environments. from Brazil, Cuba, Gambia, Bahrain, Malaysia (Sabah), Singapore, and Sri Lanka (Murphy, 1971). The species was described from Brazil and dedicated to Professor Paulo Sawaya (so the correct name is Pseudanurida sawayai and not P. sawayana, as originally described and cited in many articles). In the same year of Schuster's description, Murphy (1965) characterized and illustrated a series of specimens from Gambia, including the complete dorsal chaetotaxy, which were identified as Pseudanurida cf. bogoyawlenskyi (Baker, 1905); however, later Murphy (1971) recognized that those specimens were actually of P. sawayai. The species was described from Brazil (Recife: Barra das Jangadas) in a creek connecting Rio Pirapama and Rio Jaboatão, a few km South of Piedade Marine Biol. Station, in mangroves; nevertheless after Murphy (1971) it also has been found in Gambia (West Africa) in mangroves and rocky shore; Sabah (North Borneo), Labuan on weed-covered rocks, small inlet inside Labuan town at low tide; Singapore, Pasir Ris, sparse mangroves by small stream; Bahrain, Persian Gulf, edge of inland, fresh-water stream (maybe of artesian origin); Ceylon, Mendel lake (a brackish lagoon on the West coast) and in Mannar, Giant's tank (a large, inland, artificial fresh-water lake). It was found by Christiansen & Bellinger (1988) in mangroves of Puerto Rico, and also under and on rocks in Florida, USA. Now is has been found in sandy beach, so it seems that this species can live in different habitats., Published as part of Palacios-Vargas, José G. & Bu, Yun, 2020, New records of Collembola from marine littoral sand of Hainan Island, China with description of a new Oudemansia species (Neanuridae: Pseudachorutinae), pp. 117-130 in Zootaxa 4810 (1) on page 118, DOI: 10.11646/zootaxa.4810.1.6, http://zenodo.org/record/3937118, {"references":["Schuster, R.

Willemia panamaensis sp. nov. is close to W. brevispina Hüther, 1962. The main differences are as follows. In the new species Ant. IV has four sensilla (d, e2, i and i1) and microsensillum v is close to e2 and e3, Ant. III organ has one ms at mid-region of the organ, and is not lateral as in W. brevispina; abdominal setae and sensilla are twice as long on the distal segments of the new species than on W. brevispina. The two species share a similar number of vesicles in PAO. We list other differences in Table 1. Similar characters are: shape of apical vesicle on Ant. IV; two globular sensilla (e3(S4), i2 (S7)); c1 seta on head absent; 3+3 setae on thorax I; tibiotarsi I–III with 12 setae each; Abd. V with sensillum position at p2; a3 setae on abdominal sternite II absent; a3 seta on abdominal sternite IV present; m1 setae on abdominal sternite IV. The new species was collected in tropical rainforest soil from Barro Colorado Island, Panamá, during the dry season. No males were collected. Five specimens were sequenced for the standard COI-5P marker (“DNA barcode”, Ratnasingham & Hebert 2013) at the Canadian Centre for DNA Barcoding. DNA was successfully recovered from two specimens, sequences BCICL047-19 (length 624bp) and BCICL048-19 (655bp), which were deposited in the project BCICL of the Barcode of Life Data System (http://www.barcodinglife.org/index.php ).

Pseudachorutinae of dark blue/purple background colours and white/yellowish spots on antennae and head, thorax and abdomen, specimens of big size. Antennal, body segments and manubrium with hypertrichoses. Sensorial organ of antennal segment III displaced to Ant. IV. Ant. IV with apical bulb trilobed, ventral file with many modified setae. 5 eyes per side. Postantennal organ very small and moruliform. Mouth parts very thin and elongated, maxilla with two lamellae, one with an apical hook and mandible with one subapical tooth. Mouth forming a long buccal beak. Labrum with formula 4/ 2, 4, 2, 2. Labium with tuberculate seta L displaced apically and bifid. Paired pseudocelli present on head, thorax and abdomen. Paratergal areas moderately or well-developed on thorax and abdomen, pretergal and postergal segments with setae on thorax and abdominal segments I and II. Furcula well developed with many setae on manubrium and six dental setae. Mucro straight without any lamella. Etymology. The genus is named Sernatropiella in honour of Prof. Francisco Serna from the National University of Colombia, and -tropiella for being from the tropical region and having some similarities with genus Neotropiella. The new genus is feminine. Discussion. Most important differences between Sernatropiella gen. nov. and Neotropiella Handschin, 1942 are that the new genus has a strong hypertrichosis on antennal segments, body and manubrium; well-developed pretergal and postergal segments with dorsal setae; presence of pseudocelli (not mentioned in the description of N. malkini by Arl��, 1981) on head, thorax and abdomen; straight triangular mucro, without lamella. Other important differences with this and other genera are shown in Table 1. Both species of the new genus are distributed in the Northern part of the South American Transition Zone (Morrone 2015) in elevations close to 3.000 m above sea level., Published as part of Palacios-Vargas, Jos�� G., 2019, An extraordinary new genus and species of Pseudachorutinae (Collembola: Neanuridae) from Colombia, pp. 373-387 in Zootaxa 4609 (2) on page 374, DOI: 10.11646/zootaxa.4609.2.11, http://zenodo.org/record/3187541, {"references":["Handschin, E.

Males are smaller than females, the only other difference between sexes is in shape and chaetotaxy of genital area, 18 microsetae in males (Fig. 6D) vs. 10 in females. Remarks. N. fimbriatus is very different to N. desantisi Najt, 1971, the only other species known in Southamerica. If differs by the absence of stouter and longer lanceolate spines around thoracic s.f. and macrosetae on posterior part of abdomen. Other differences are that N. desantisi has only 1+1 apical seta on ventral tube and only 2 conical spines on postero-external surface of distal dens. Being those characters unknown in other member of the genus, what makes a revision of type material needed. Photos of types were sent to us, by they are dried up and need to be remounted for proper study. N. fimbriatus clearly differs from other Neelus species by the absence lanceolate anterior spines around thoracal s.f. Moreover, it has small body size of all Neelus congeners. Original description of N. fimbriatus was based on 3 females and one juvenile (in alcohol), 2 females and one male under slides and 2 alcoholic specimens from other sample. They were from Otonga, Cotopaxi Province, Ecuador, at 1,900 m alt. July, 1998. Ours come from Guacarí, Valle del Cauca, Colombia. The only diagnostic characters mentioned by Bretfeld & Trinklein (2000) are: “upper setae pair of ventral head-back ciliate (apomorphy), setae of labial row “a” thick and roughly serrate (apomorphy), posterior side of dentes with 1 + 1 basal setae (other 2+2)”. In addition, they mention the “Total length up to 0.5 mm, length of neosminthururoid setae 6–7 µm. Manubrium: dens: mucro = 1.7:1.8:1. In our specimens this ratio is 0.78: 1.6: 1. Original description the labrum is very accurate, but basoextenal field of labium was not illustrated. Fig. 9 of Bretfeld & Trinklein (2000) does not illustrate the dental spurs AJ1 and AE1. The ratio of antennal segments of our specimens is very similar to that found by Schneider (2017) but the number of setae Ant. II is 4 in ours (5 after Schneider) The total length of the antenna in Colombian specimens is 117–120 µm, shorter than those of type material (143 µm). Organite “Or” also with two apical filaments. Genital plate of male with only 9 + 9 setae and not 13 + 13 as in the type material. In the discussion, Schneider (2017) states that N. fimbriatus differs from Neelus murinus and Neelus koseli in antennal chaetotaxy, labral setae morphology and post-labial setae morphology. Neelus koseli and N. murinus have 6 setae on Ant. II, our specimens from Colombia have 4 setae and the redescription of Schneider illustrate 5 setae in Fig. 36A. As the only real diagnostic character of N. fimbriatus is the barbulate seta of the post-labial area of the head, we must consider our specimens belonging to this species.

Neelus Folsom, 1896 Modified diagnosis. Six pairs of sensory fields: 1 below and 1 above antennae,1 laterally on Th II, 1 on subcoxa II, 1 on thorax III and 1 posteriorly on large abdomen (this sensory field with 2 marginal setae). With one neosminthuroid setae laterally on Abd. IV sternum. Antennal segments well divided, Ant. IV longer than III, but of the same width. Ant. IV with a big sensillum, and a small one, one forked subapical organ and 7–9 long sensilla. Sensorial organ of Ant. III with two central small sensilla and two guard sensilla, one dorsal and a bigger ventral, one ventral microsensillum spine-shaped. Ungues without external teeth, with one ventral teeth and two lateral (pseudonychia). Tenent hairs absent. Empodium without apical filament and teeth. Empodial tubercle small. Ventral tube with two apical setae, posterior face with a distinct lobe. Retinaculum with 3+3 teeth and corpus without seta. Furcula long and strong. Manubrium posteriorly with six or eight setae and anteriorly at the apex with a pair of articular convex processes. Dens with one seta. Posterior surface of dens proximal with 1-2 setae.

The specific name “ hypergranulosa ” refers to heavy integumentary granulation present on the whole body. Remarks. Due to cerotegumentary granulation, P. hypergranulosa sp. nov. resembles Pergalumna granulatus Balogh & Mahunka, 1967 (Vietnam), from which it differs by only unilaterally barbed bothridial setae and a more heaver granulation. Pergalumna elongatiporosa Ermilov et al. 2014 (Costa Rica), has elongated and folded porose areas A1, giving a horseshoe aspect, while in this new species they are straight. It is also similar to Pergalumna paralongisetosa Ermilov & Kalúz, 2012 (from Ecuador), which shows a granulated cerotegument only on the prodorsum, while the notogaster is smooth; also bothridial setae (bs) are shorter than interlamellar setae (in), adanal setae are extremely long, and there is also a considerable difference in the size of the body (L= 1062–1261, W=713–863 vs. L=470–490, W=350–390). Finally, Pergalumna silvatica Hammer, 1961 (Peru) also shows a granulated anterior region of the prodorsum, but interlamellar setae in are minute, and there are four pairs of round notogastric porose areas while P. hypergranulosa sp. nov. has only three pairs and all are elongated.

This material is deposited in the collection of Collembola de M��xico y ��caros Ed��ficos of Laboratorio de Ecolog��a y Sistem��tica de Microartr��podos (LESM), Facultad de Ciencias, UNAM. Etymology. The specific name ��� dactylaris ��� describes the similarity of the integumentary ornamentation with human fingerprints. Remarks. The ornamentation on the prodorsum and notogaster of P. dactylaris sp. nov. resembles Pergalumna striata (P��rez-����igo & Baggio, 1980), from Brazil, but can be distinguished by the presence of only three notogastric porosea areas instead of four, and being almost twice as long as in P. striata (400���440). The shape of bothridial setae bs is similar to Pergalumna decorata Balogh & Mahunka, 1977 (Bolivia), which has Aa closer to lm than la, whereas in P. dactylaris sp. nov. Aa is located exactly in the middle between them; besides interlamellar setae in are short, but not minute, and the Bolivian species is much smaller (L=637���653, W=469��� 494) than the Mexican (L=838���986, W=720���789). New species is also similar to Pergalumna decoratissima P��rez-����igo & Baggio, 1986 (Ecuador) which has a granulated prodorsum and the rest of the body ornamented with longitudinal striae or grooves, however, lamellar setae (le) in this species is more than twice as long as rostral setae (ro), and the anal and genital plates are ornamented in the same manner, while in P. dactylaris sp. nov. prodorsal setae le and ro are subequal in size, also genital and anal plates are ornamented with different patterns, with less ornamentations on genital plate. Finally Pergalumna paradecoratissima Ermilov & Kal��z, 2012 (Ecuador) differs by having a tooth-shaped projection on each side of prodorsum, anal plate smooth and the presence of one small and oval porose area postanalis. In addition, P. dactylaris sp. nov. seems to be the only species with a clear and well delimitated lenticular region between prodorsum and the base of notogaster. Sympatric speciation. The three species come from Los Tuxtlas, Veracruz, and as they live in the same locality and biotope, it seems that a sympatric speciation has occurred. We have analyzed the chelicerae, but we have not found any important difference, but we think that each of them is using a new niche, which had reduced gene flow with individuals exploiting another niche. Unpublished data support this, Villagomez (2015) performed techniques of extraction and amplification of ribosomal 18S rRNA and mitochondrial Cytochrome Oxidase c 1 (Cox 1) for molecular characterization of these species and to delimit the relationship between genetic distance and morphological characters. The results show that genetic distance between species with molecular marker Cox 1 observed in the three species varies from 0.3, 2.46 or 6.02%., Published as part of Palacios-Vargas, Jos�� G. & Villagomez, Fernando, 2017, Three new species of Pergalumna (Acari: Oribatida: Galumnidae) from the tropical rainforest of Veracruz, Mexico, pp. 77-94 in Zootaxa 4242 (1) on pages 88-91, DOI: 10.11646/zootaxa.4242.1.4, http://zenodo.org/record/376008, {"references":["Perez-Inigo, C. & Baggio, D.

Key for the genera of Sensillanurini 1 Presence of Di tubercle and one seta on Th. I...................................................... Sensillanura - Lacking Di tubercle and seta on Th. I..................................................................... 2 2 Dorsal tubercles developed and “finger-like”; S 2 hypertrophied and thickened similar to S 7 on Ant. IV..................................................................................................... Tabasconura gen. nov. - Dorsal tubercles not elongated; S 2 not hypertrophied, thin and short, similar to others except S 7....................... 3 3 Cephalic tubercle De with 3 ‒ 1 setae, two or one setae on tubercle Di of Abd. IV and V; dorsal macrosetae smooth or barbulate; 6 or 8 setae between the sensorial setae on Abd. IV and 6 setae between the sensorial setae on Abd. V........ Americanura - Cephalic tubercle De always with 1 seta; only one seta on tubercle Di of Abd. IV and V; dorsal macrosetae palmate with ser- rate margins; 4 and 2 setae between the sensorial setae on Abd. IV and V respectively....................... Palmanura
