Family Halophilosciidae Verhoeff, 1908 Remarks The family Halophilosciidae comprises 34 species distributed in three genera, Halophiloscia Verhoeff, 1908 (9 spp.), Littorophiloscia Hatch, 1947 (22 spp.), and Stenophiloscia Verhoeff, 1908 (3 spp.) (WoRMS 2020c). In Colombia, Pearse (1915) recorded Philoscia culebrae Moore, 1901 [= Littorophiloscia c.] in coffee plantations from Hacienda Cincinati and Hacienda La Rosa, Sierra Nevada de Santa Marta (ca 1400 m a.s.l.), which is considered to be a misidentification by Van Name (1936). Littorophiloscia culebrae (Moore, 1901) is recorded from coastal areas of Angola, Brazil, Canary Islands, Caribbean islands, Florida (USA), Hawaii, Iraq, Madagascar, Socotra Archipelago and Yemen (Schmalfuss 2003; Taiti & Ferrara 2004; Araujo & Taiti 2007; Taiti & Lopez 2008; Naser et al. 2015; Lisboa et al. 2017; Campos-Filho et al. 2018).

Composed of three articles subequal in length, distal article with two lateral aesthetascs plus apical pair (Fig. 15F). ANTENNA. When extended posteriorly reaches posterior margin of pereonite 5; flagellum as long as fifth article of peduncle, first article slightly longer than second and third, second and third articles with three and two lateral aesthetascs, respectively (Fig. 15G). MOUTH. Mandibles with molar penicil consisting of at least five branches, left mandible with 2+1 penicils (Fig. 16A), right mandible with 1+1 penicils (Fig. 16B). Maxillula (Fig. 16C) inner endite with two long penicils inserted transversely; outer endite of 5+5 teeth, inner set apically cleft. Maxilla (Fig. 16D) with bilobate apex, inner lobe rounded, bearing thick setae, outer lobe rounded, covered with thin setae plus three thick setae.

Pleopod 1 (Fig. 17D) exopod triangular, inner margin almost straight, outer margin sinuous, distal portion triangular with distal margin rounded; endopod with thickest distal part with sides almost parallel, inner distal part with long pointed process concave on outer margin, prominent subquadrangular apical lobe on outer distal portion bearing thin setae. Pleopod 2 (Fig. 17E) exopod triangular, outer margin concave, bearing seven stout setae; endopod robust, distinctly longer than exopod. Exopods of pleopods 3–5 as in Fig. 17F–H. Remarks Vandel (1973) erected the genus Microphiloscia to allocate the new species M. trichoniscoides from Cueva de la Colorada, Provincia de Oriente, Sierra Maestra, Colorada del Maso, Cuba. After the examination of material belonging to this species, M. trichoniscoides shows the shape of the genital papilla and male pleopod 1 endopod typical of members of Halophiloscia (see also Taiti & Lopez 2008). Halophiloscia includes 9 halophilic species mainly distributed along the Mediterranean and Atlantic coasts of Europe and Africa (Schmalfuss 2003; Taiti & Lopez 2008; Taiti & Argano 2009, 2011). In America, only H. couchii (Kinahan, 1858) was recorded, from Argentina, Bermuda, and USA (see Schmidt 2003). The genus is mainly characterized by the runner-type habitus (sensu Schmalfuss 1984), epimera of pereonites 1–7 with one or more lines of noduli laterales, male pereopod 1 and sometimes pereopod 2 carpus and propodus enlarged and covered with several scales on frontal side, male genital papilla distally bifurcated, and male pleopod 1 endopod stout bearing a long, pointed process on the apex (see Schmidt 2003; Taiti & Lopez 2008). The species is included within the genus since it shows all the previously mentioned characters, except that the male pereopods 1 and 2 do not have the carpus and propodus enlarged. Thus, Microphiloscia is considered to be a junior synonym of Halophiloscia. Distribution Cuba (Vandel 1973). First record for Colombia.

Remarks In the Caribbean region, four species of Armadilloniscus have been recorded: A. caraibicus from Venezuela, A. ellipticus (Harger, 1878) from the Atlantic coasts of USA and Bermuda, A. ninae Schultz, 1984 from Belize, and A. steptus Schotte & Heard, 1991 from Turks and Caicos Islands (British West Indies) (Schultz 1984; Paoletti & Stinner 1989; Taiti & Ferrara 1989; Schotte & Heard 1991). For a definition of the genus see Arcangeli (1957), Vandel (1962), Taiti & Ferrara (1989), and Schmidt (2002). Armadilloniscus luisi Carpio-D��az, Taiti & Campos-Filho sp. nov. is readily distinguished from all the other species of the genus in the number and arrangement of the dorsal tubercles on the cephalon, pereon and pleon. Moreover, it can be distinguished from the other four Caribbean species in having two broad tubercles on pleonite 2 (vs small in A. caraibicus and A. steptus, absent in A. ninae), the cephalon with the median lobe triangular (vs rounded in A. caraibicus) and lateral lobes subquadrangular (vs subtriangular in A. ninae and A. steptus), eyes composed of four ommatidia (vs 4���5 in A. caraibicus, 6 in A. ellipticus and 5 in A. ninae), telson with distal margin truncate (vs rounded in A. caraibicus and A. ellipticus, triangular in A. ninae), and ♂ pleopod 1 exopod ovoid (vs subtriangular in A. caraibicus, A. ellipticus and A. ninae, almost rounded in A. steptus) (Paoletti & Stinner 1989; Schultz 1984; Schotte & Heard 1991; Garthwaite et al. 1992; Schmidt 2002).

Distribution This species was originally described from Veracruz, Mexico (but see Discussion). Molecular phylogenetic analyses, however, revealed that what has been denominated as this species corresponds to a clade composed of highly divergent lineages (probably a complex of cryptic species), distributed in southern Florida, across the Caribbean Sea, Bahamas, Bermuda, and probably in northern Brazil, and the Pacific coast from Costa Rica, Panam��, Colombia, probably to Ecuador (Santamaria et al. 2014). Although this species has been reported in the Gulf of California and California, extensive sampling for phylogeographic studies conducted by some of us suggest that these previous records are likely misidentifications (Hurtado et al. 2010; Eberl et al. 2013; Hurtado et al. 2018)., Published as part of L��pez-Orozco, Carlos Mario, Carpio-D��az, Yesenia M., Borja-Arrieta, Ricardo, Navas-S, Gabriel R., Campos-Filho, Ivanklin Soares, Taiti, Stefano, Mateos, Mariana, Olazaran, Alexandra, Caballero, Isabel C., Jotty, Karick, G��mez-Estrada, Harold & Hurtado, Luis A., 2022, A glimpse into a remarkable unknown diversity of oniscideans along the Caribbean coasts revealed on a tiny island, pp. 1-50 in European Journal of Taxonomy 793 on page 7, DOI: 10.5852/ejt.2022.793.1643, http://zenodo.org/record/6037892, {"references":["Milne-Edwards M. 1840.

Epimera of pereonites 2���7 laterally grooved (Fig. 6B). Pereonites 4���5 ventrally with lateral sternal thickenings small, triangular; pereonites 6 and 7 ventrally with sub-rectangular sternal plates (Fig. 6C). PLEON. Pleonite 2 dorsally visible, 3���5 with rectangular epimera (Fig. 6A���C). Telson (Fig. 6G) trapezoidal, distal margin broadly rounded. ANTENNULA. Composed of two articles (Fig. 6H), proximal article stout with shield-like projection on distal margin, distal article comma-shaped bearing two distal aesthetascs. ANTENNA. Short (Fig. 6I), peduncle articles more or less subequal in length; flagellum of two articles, distal article twice as long as proximal article, bearing two lateral aesthetascs. MOUTH.

Pereopods 1���7 short, stout, merus to propodus bearing sparse setae on sternal margins; pereopod 1 carpus with distal seta fringed at apex; dactylus of two claws, inner claw very short, ungual seta simple, not surpassing outer claw, dactylar seta stout, reaching distal margin of outer claw, apex bearing many small setae. Male PEREOPODS 1 AND 7. Without sexual dimorphism (Fig. 8A���B). PLEOPODS. Pleopod 1 exopod absent; endopod (Fig. 8C) enlarged on proximal portion, distal portion tapering. Pleopod 2 (Fig. 8D) exopod triangular, inner margin grooved, bearing one strong seta; endopod about twice as long as exopod. Pleopod 3 and 4 exopods (Fig. 8E���F) sub-quadrangular, inner margin grooved, distal margin slightly serrate. Pleopod 5 exopod (Fig. 8G) sub-rectangular, inner margin slightly serrate, distal margin straight, bearing one seta. Remarks Presently, Stenoniscus comprises four species (Schmalfuss 2003): S. pleonalis Aubert & Dollfus, 1890 from the northern coasts of the Mediterranean east to the Aegean, Bermuda, Bulgaria, Madeira and Mexico; S. carinatus Silvestri, 1897 from coastal areas of Croatia, Italy, Portugal and Spain; S. aenariensis (Verhoeff, 1942) and S. plutonis (Verhoeff, 1942) from Ischia Island, Italy, both most probably junior synonyms of S. pleonalis according to the short descriptions by Verhoeff (1942). The genus can be defined by animals of reduced size (up to 3.5 mm), body slender with lateral sides parallel, dorsum bearing longitudinal ribs and tubercles, sometimes reduced, epimera of pereonites 2���7 with lateral margins grooved, pereonites 4���5 ventrally with lateral sternal thickenings and 6���7 with sternal plates, antennula of two articles, pleonite 1 absent, uropods of conical shape, pleopod exopods without respiratory organs, and pleopod 1 absent on females (see Vandel 1962; Schmidt 2003). Stenoniscus nestori L��pez-Orozco, Taiti & Campos-Filho sp. nov. is morphologically similar to Stenoniscus carinatus, from which it differs mainly in the number and disposition of the dorsal ribs and tubercles on the cephalon and pereonites (compare Fig. 6A���B with Schmidt 2003: fig. 67 and Taiti & Ferrara 1982: fig. 6a for S. carinatus). The new species is readily distinct from Stenoniscus pleonalis in having a strong dorsal ornamentation (vs very weak) and lacking the tomentose appearance due to long dorsal scale-setae (see Vandel 1944: fig. 1a���c).

Distribution Brazil and Haiti (Schmalfuss 2003; Campos-Filho et al. 2017). First record for Colombia. Molecular phylogenetic analyses of Tylos Audouin, 1826 Sequences obtained for the three species of Tylos from Isla Grande and the specimen from Florida have been deposited under GenBank Accession Numbers MW532964 ��� MW532970 and MW533069 ��� MW533075. Only the 12S rDNA sequence was obtained for the specimen from Isla Grande assigned to T. marcuzzii. Phylogenetic analyses using only 12S rDNA group this sequence with the two specimens of T. marcuzzii from Cuba reported in Hurtado et al. (2014); see Fig. 18. The 12S rDNA p-distance between T. marcuzzii from Isla Grande and T. marcuzzii from Cuba is 2.0���2.7%, whereas the distance between the specimens from the two Cuban localities is 2.0% (Table 2). Only the 16S rDNA sequence was obtained for the specimen of T. niveus from the Florida Keys, the type locality of this species. Phylogenetic analyses of 16S rDNA show that specimens identified as T. niveus from Isla Grande are most closely related to the T. niveus specimen from the Florida Keys. The 16S rDNA p-distance between T. niveus from Isla Grande and the Florida Keys is 2.7% (Table 2). The concatenated (12S rDNA and 16S rDNA) dataset was comprised of 43 taxa and 740 characters (excluding characters with ambiguous homology), 236 of which were parsimony-informative. The specimens assigned to T. marcuzzii were used as outgroup. Five main lineages were identified for the ingroup taxa in the concatenated phylogenetic analyses, which formed a basal polytomy (Fig. 18): (1) T. niveus from Puerto Rico; (2) Tylos sp. from Yaguanabo, Cuba; (3) T. niveus from Florida and Isla Grande; (4) T. negroi sp. nov.; and (5) Tylos punctatus sensu lato from the Northeastern Pacific. The range of 16S rDNA and 12S rDNA p-distances between the four basal lineages excluding T. punctatus is 11.1���13.6% and 9.7���15.5%, respectively. The range of 16S rDNA and 12S rDNA p-distances between these ingroup lineages and T. marcuzzii is 19.4���22.2% and 19.5���23.8%, respectively., Published as part of L��pez-Orozco, Carlos Mario, Carpio-D��az, Yesenia M., Borja-Arrieta, Ricardo, Navas-S, Gabriel R., Campos-Filho, Ivanklin Soares, Taiti, Stefano, Mateos, Mariana, Olazaran, Alexandra, Caballero, Isabel C., Jotty, Karick, G��mez-Estrada, Harold & Hurtado, Luis A., 2022, A glimpse into a remarkable unknown diversity of oniscideans along the Caribbean coasts revealed on a tiny island, pp. 1-50 in European Journal of Taxonomy 793 on page 38, DOI: 10.5852/ejt.2022.793.1643, http://zenodo.org/record/6037892, {"references":["Budde-Lund G. 1904.

Remarks Presently, the genus Tylos has a worldwide distribution and comprises 21 coastal species (Schmalfuss & Vergara 2000; Schmalfuss 2003). In Colombia, only T. niveus Budde-Lund, 1885 was recorded from the Caribbean region (Carpio-D��az et al. 2016). Tylos negroi sp. nov. can be distinguished from all species of the genus by the shape of the ventral phylacomera 5. Moreover, it differs from T. niveus in the pereonite 1 epimeron having the inner lobe of the schisma surpassing the outer lobe (vs inner lobe not surpassing outer lobe) and the pereopod 7 propodus being inflated (vs not inflated).

Family Detonidae Budde-Lund, 1904 Remarks The family Detonidae Budde-Lund, 1904 comprises 39 littoral species in the genera Armadilloniscus Uljanin, 1875 (32 spp.), Deto Gu��rin-M��neville, 1836 (5 spp.) and Detonella Lohmander, 1927 (2 spp.), including two dubious species, Armadilloniscus minutus Uljanin, 1875 and Deto spinicornis Brandt, 1851 (Schultz 1984; Paoletti & Stinner 1989; Taiti & Ferrara 1989; Schmidt 2002; Schmalfuss 2003; Schmidt & Leistikow 2004; WoRMS 2020b). The family can be characterized by animals having a clinger habitus (sensu Schmalfuss 1984), cephalon with well-developed lateral lobes, dorsal surface more or less tuberculated or with longitudinal ridges, exopods of pleopods 1���5 without respiratory structures and lateral margins covered with thin setae conferring a fringe-like appearance (see Taiti & Ferrara 1989; Schmidt 2002). Recently, Reinoso-Fl��rez et al. (2016) recorded the family from P��ramo de Estambul (Tolima), Colombia. However, after the re-examination of the material deposited at Colecci��n Zool��gica de la Universidad del Tolima (CZUT-IT 1423���1426, see Reinoso-Fl��rez et al. 2016), the specimens belong to the families Styloniscidae and Philosciidae, and therefore, our work constitutes the first record of the family in the country., Published as part of L��pez-Orozco, Carlos Mario, Carpio-D��az, Yesenia M., Borja-Arrieta, Ricardo, Navas-S, Gabriel R., Campos-Filho, Ivanklin Soares, Taiti, Stefano, Mateos, Mariana, Olazaran, Alexandra, Caballero, Isabel C., Jotty, Karick, G��mez-Estrada, Harold & Hurtado, Luis A., 2022, A glimpse into a remarkable unknown diversity of oniscideans along the Caribbean coasts revealed on a tiny island, pp. 1-50 in European Journal of Taxonomy 793 on page 19, DOI: 10.5852/ejt.2022.793.1643, http://zenodo.org/record/6037892, {"references":["Budde-Lund G. 1904.

Remarks In the Caribbean region, four species of Armadilloniscus have been recorded: A. caraibicus from Venezuela, A. ellipticus (Harger, 1878) from the Atlantic coasts of USA and Bermuda, A. ninae Schultz, 1984 from Belize, and A. steptus Schotte & Heard, 1991 from Turks and Caicos Islands (British West Indies) (Schultz 1984; Paoletti & Stinner 1989; Taiti & Ferrara 1989; Schotte & Heard 1991). For a definition of the genus see Arcangeli (1957), Vandel (1962), Taiti & Ferrara (1989), and Schmidt (2002). Armadilloniscus luisi Carpio-Díaz, Taiti & Campos-Filho sp. nov. is readily distinguished from all the other species of the genus in the number and arrangement of the dorsal tubercles on the cephalon, pereon and pleon. Moreover, it can be distinguished from the other four Caribbean species in having two broad tubercles on pleonite 2 (vs small in A. caraibicus and A. steptus, absent in A. ninae), the cephalon with the median lobe triangular (vs rounded in A. caraibicus) and lateral lobes subquadrangular (vs subtriangular in A. ninae and A. steptus), eyes composed of four ommatidia (vs 4–5 in A. caraibicus, 6 in A. ellipticus and 5 in A. ninae), telson with distal margin truncate (vs rounded in A. caraibicus and A. ellipticus, triangular in A. ninae), and ♂ pleopod 1 exopod ovoid (vs subtriangular in A. caraibicus, A. ellipticus and A. ninae, almost rounded in A. steptus) (Paoletti & Stinner 1989; Schultz 1984; Schotte & Heard 1991; Garthwaite et al. 1992; Schmidt 2002). Distribution Presently known only from Isla Grande, Cartagena de Indias, Colombia.
