682387A908208463FF49E04E1BA4FD0B.taxon	discussion	Remark. The original spelling of the family-group name Ochyroceratidae was not formed in accordance with Article 29.3 of the International Code of Zoological Nomenclature (ICZN) (1999), as the stem of the type genus Ochyrocera is Ochyrocer -, therefore the correct family-group name should be Ochyroceridae (to be Ochyroceratidae, the type genus should be Ochyroceras, stem Ochyrocerat -). To our knowledge the name Ochyroceridae has been previously used in four articles (Gerhardt 1930; Slowik & Sikes 2011; Wunderlich 2012, 2015), but in three of them there is evidence that it was used as a misspelling of Ochyroceratidae. Here we maintain the original spelling Ochyroceratidae according to the Article 29.5 of the ICZN, which allows the maintenance of current spellings in prevailing usage, whether or not their derivation from the name of the type genus is in accordance with the grammatical procedures in Articles 29.3.1 and 29.3.2.	en	Pérez-González, Abel, Magalhaes, Ivan L.

682387A908208462FF49E3921DFBFB03.taxon	discussion	Remarks. Pandeus was established by Keyserling (1891) for a Brazilian species, and Ochyrocera was established by Simon (1892) for a Lesser Antillean species. Simon’s work was scheduled to be published on November 17, 1891, and thus nearly simultaneously with that of Keyserling. However, Simon’s paper was not published until April 1892 (see Duncan 1937). We are unaware of any evidence indicating that Keyserling’s work was published after 1891 and thus we consider December 31 st of 1891 as its publication date, according to ICZN Article 21.2. Consequently, the name Pandeus has priority over Ochyrocera. However, Pandeus was, very early, considered a junior synonym of Ochyrocera by Simon (1895: 1068). This decision was followed in the first revision of the family (Fage 1912), by all subsequent catalogs (e. g., Petrunkevitch 1911; Bonnet 1958; WSC 2024 etc.), and by all recent authors working on the taxonomy of the family (see a list of publications below). Bonnet (1958: 3122) argued that “ it could be that Keyserling's term [referring to Pandeus] is a few weeks earlier than Simon's [referring to Ochyrocera], but, even if the demonstration were made, I do not advise today, for this reason alone, to reject Ochyrocera, which has been widely used until now. ”. Still, we are confronted with the fact that Pandeus is the older name. However, we here argue that the younger Ochyrocera must be retained as the valid name as a nomen protectum, as it fulfills both conditions of ICZN Article 23.9 that warrant a reversal of precedence: (1) Pandeus has never been used as a valid name after Simon (1895) synonymized it. Mentions of this genus by subsequent authors (e. g., Brignoli 1979; Pérez-González et al. 2016; Brescovit et al. 2018) only indicate its synonymy with Ochyrocera and refer to its availability as a generic name in the eventual case that Ochyrocera should be split. (2) The younger Ochyrocera has been used as a “ presumed valid name, in at least 25 works, published by at least 10 authors in the immediately preceding 50 years and encompassing a span of not less than 10 years ”. This is evidenced by the following 34 publications, made by 26 different first authors (94 different authors in total) in the preceding 46 years, all of which mention Ochyrocera at least once: Baert 2014; Baptista et al. 2008; Brescovit et al. 2018, 2021 a, 2021 b; Brignoli 1978, 1979; Cabra-García et al. 2010; Castanheira et al. 2019; De los Santos & Carrero Jiménez 2015; Dumitrescu & Georgescu 1992; Dupérré 2015, 2023; Emerit & Lopez 1985; González-Sponga 2001; Hormiga et al. 2007; Huber 2004; Král et al. 2006; Kulkarni et al. 2023; Labarque et al. 2018; Li et al. 2020; Lopez & Lopez 1997; Magalhaes et al. 2019, 2021, 2022; Michalik et al. 2019; Penney 2008; Pérez-González et al. 2016; Ramírez et al. 2023; Ribera 1978; Valdez-Mondragón & Chamé-Vázquez 2023; Valdez-Mondragón 2009, 2017, and Wheeler et al. 2017. We thus proposed the older name Pandeus as a nomen oblitum and the younger but valid Ochyrocera name as a nomen protectum. It should be noted that Pandeus remains available and could be restored in the case the two genera are no longer considered subjective synonyms.	en	Pérez-González, Abel, Magalhaes, Ivan L. F.

682387A90821846FFF49E5871855FE57.taxon	diagnosis	Diagnosis. Can be distinguished from congeners by the following combination of characteristics: cephalothorax without two pointed tubercles behind the ALE; clypeus unarmed; chelicerae sexually monomorphic, male pedipalp with conical cymbium with a very long sub-apical finger-like apophysis; tegulum large, ovoid, with a slender mostly tubular embolus (2 times the tegulum length) oriented in a very acute angle with respect to the longitudinal axis of the tegulum, and with a slightly sinuous base; females with two chitinized abdominal pockets on the sides of the female abdomen; vulva with two weakly sclerotized wide putative receptacles and with a short columnar uterus externus ending in a very narrow neck. Can be easily separated from the morphologically closest species, O. luisarmasi sp. nov., by the shorter cymbium and the heavily sclerotized tubular embolus oriented in a very acute angle (Figs 1 A – C, 4 B). Regarding the female, O. mayabeque sp. nov. can be differentiated from O. luisarmasi sp. nov. by a shorter columnar uterus externus, and larger receptacles and pore plates (Figs 2 A, 3 A).	en	Pérez-González, Abel, Magalhaes, Ivan L.

The species epithet is a noun in apposition taken from " Sierra Maestra ", the Spanish name for the Eastern Cuban range mountains where the type locality is found. Aside from this, the species name has two other oblique references: on one side, " maestra " means teacher, and this is an allusion to how much this species helps us to understand " Fageicera " morphology; on the other side, it is an allusion to the fact that the Cuban arachnologist, Dr. Luis F. de Armas, was the first arachnological teacher of the first author (APG), and this is an acknowledgment of all the knowledge and teaching transmitted along many years.	en	Pérez-González, Abel, Magalhaes, Ivan L.

682387A9082C8471FF49E3571D8BFADB.taxon	diagnosis	Diagnosis. Can be distinguished from congeners by the following combination of characteristics: cephalothorax without two pointed tubercles behind the ALE; clypeus sexually dimorphic armed in males with a large, wide, and apically bilobated prominence, roughly cordiform; chelicerae sexually dimorphic, with a strong, straight triangular projection (as large as the clypear prominence) in males; male pedipalp with conical cymbium with a very long sub-apical finger-like apophysis; embolus mostly straight, with small pointed paraembolic lamina; females with four small chitinous abdominal pockets; vulva with a pair of thin and extremely elongated spermathecae (about 50 times as long as wide) and with uterus externus not columnar, undivided, ending in a very narrow neck. Can be easily separated from the morphologically closest species, O. cubana, by a larger and bilobated clypear prominence (Fig. 10 C, D, F) and shorter and straight cheliceral triangular projection (Fig. 10 F) in males and by remarkably more elongated spermathecae (Figs 2 D, 3 C). Male pedipalp morphology and clypear and cheliceral armature also easily separate this species with other close morphological species formerly combined in Fageicera: Ochyrocera loma, O. nasuta and O. matarredondensis. The Ecuadorian Ochyrocera minotaure Dupérré, 2015, has two clypeal horns instead of a single prominence as in O. maestra sp. nov. and O. cashcatotoras Dupérré, 2015, also have a modified carapace with males exhibiting a unique spine-liked projection, but this modification is situated between the PME and not in the clypeus. Other species with sexually dimorphic cuticular projections on the chelicerae are the morphologically close O. thibaudi Emerit & Lopez, 1985, from the Lesser Antilles, O. caeruleoamethystina Lopez & Lopez, 1997, from French Guyana, and the highly derived O. peruana Ribera, 1978, but the modifications on these species are quite different to the strong straight triangular projection of O. maestra sp. nov.	en	Pérez-González, Abel, Magalhaes, Ivan L.

Chelicerae are entirely moderate yellow. Endites and sternum moderate yellow with remnants of light green pigmentation barely distinguishable. Abdomen yellowish white with remnants of strong green pigmentation around the spinnerets. Palps and legs moderate yellow. PME anteriorly displaced forming a straight row with ALE. Ocular area slightly elevated. Clypeus large, armed with a big, wide, and apically bilobated prominence, covered apically with numerous setal bases in each lobe. Anterior margin of labium notched. Abdomen oval, but not markedly elongated. Chelicerae sexually dimorphic, with a strong straight triangular projection (as large as the clypear prominence) situated in the fronto-basal region closer to the medial line; well-developed lamina followed by a series of at least 6 subequal promarginal teeth. Palp (Figs 1 D – F, 2 E, 3 D): femur cylindrical larger than tibia; patella very short, tibia thicker than femur. Cymbium conical with pointed apex, 1.05 the palpal tibia length, with a very long sub-apical (and far from the pedestal) finger-like apophysis carrying a cuspule at its tip. Dorso prolateral region of the cymbium with higher number of setae including the larger and stronger ones. Cymbium basally with a protruding pedestal where the copulatory bulb inserts.

682387A908328470FF49E4AB1C06F858.taxon	diagnosis	Diagnosis. Can be distinguished from congeners by the following combination of characteristics: cephalotorax without two pointed tubercles behind the ALE; clypeus unarmed; chelicerae sexually monomorphic, male pedipalp with markedly slender conical cymbium with a very long sub-apical finger-like apophysis; tegulum large, ovoid, with a long ribbon-like embolus (1.92 times the tegulum’s length) oriented with an angle around 45 degrees with respect to the longitudinal axis of the tegulum; two chitinized abdominal pockets on the sides of the female abdomen; vulva with two weakly sclerotized wide putative receptacles and with an elongated columnar uterus externus with four constrictions ending in a very narrow neck. Can be easily separated from the morphologically closest species, O. mayabeque sp. nov., by the slender cymbium and the not heavily sclerotized and ribbon-like embolus (Figs 1 G – I, 2 F, 3 F), contrasting with O. mayabeque sp. nov., which has a shorter conical cymbium and a tubular embolus heavily sclerotized with the surface striated and twisted-like appearance (Figs 1 A – C, 3 B). In O. luisarmasi sp. nov. the embolus is oriented with an angle around 45 degrees with respect to the longitudinal axis of the tegulum, whereas in O. mayabeque sp. nov. the embolus is oriented in a very acute angle. Regarding the female, O. luisarmasi sp. nov. can be differentiated from O. mayabeque sp. nov. by a larger columnar uterus externus and smaller receptacles and pore plates (Figs 2 G, 3 E).	en	Pérez-González, Abel, Magalhaes, Ivan L.

682387A908318472FF49E1FE1BC3FCA7.taxon	discussion	Remark. Simon (1892) described the species from both sexes, and Fage (1912) studied two females and one male from Saint Vincent deposited in Simon’s collection, presumably the syntypes. The jar of Ochyrocera arietina E. S. in the MNHN collections contained a single tube with the label “ MUSEUM PARIS AR 1423 | Ochyroceratidae arictina [sic] E. S ♀ | piéces buccales | Im – St. Vincent (cb. m.) ” (C. J. Grismado, personal communication). Although the label reads ♀, the tube contained a tube with a single male lacking the abdomen, the left palp and part of the legs. We interpret this specimen as part of the original syntype series and have examined it through photos (Fig. 12). The morphology of the palp matches the drawing by Fage (1912, fig. 42), although the distal portion of the embolus is distinctly bent in the syntype, possibly a preservation artifact. The whereabouts of Simon’s female specimens are unknown, and we have made no effort to trace them.	en	Pérez-González, Abel, Magalhaes, Ivan L. F.
