Zootaxa 2023 2023-08-11 5329 1 1 150 Feitosa & Ott & Bonaldo, 2023 Feitosa & Ott & Bonaldo 2023 [151,397,151,178] Arachnida Oonopidae Hexapopha Animalia Araneae 93 94 Arthropoda species baehrae sp. nov.   Figs 61–63; Map 4   Type material:   Holotype:male from Estaç„o de Pesquisa Agropecuária – FEPAGRO, Viam„o, Rio Grande do Sul, Brazil( 30°02’17.04”S, 51°01’20.66”W),  Apr. 12, 1995, R. Ottleg., deposited in MCTP, PBI_OON 40585.   Paratypes: same data and collector as holotype, 1♁, 3♀( MCTP 8554, PBI_ OON 46377);  Jan. 12, 1996, 1♀( MCN 56852, PBI_ OON 46372).   Etymology.The specific name is a patronym honoring the arachnologist Barbara Baeher (Queensland Museum), recognizing her great contribution to the Goblin Spiders PBI.   Diagnosis.Males of this species resemble those of  H. excavata  sp. nov.and  H. numerosa  sp. nov.by the conductor nearly the same size of the embolus, without proximal projection and with single tip, endite’s P1 longitudinally oriented, not folded over itself, and by the absence of endite’s P3 ( Figs 60C,H, 66C,H); they can be distinguished from those of  H. numerosa  sp. nov.by endite’s P1 directed posteriorly ( Fig. 63C) (directed anteriorly in  H. numerosa  sp. nov.) and from those of  H. excavata  sp. nov.by the endite’s P2 represented by a large bent plate ( Fig. 63C) (a small acute process in  H. excavata  sp. nov.) Females differ from those of other species with U-shaped postepigastric scape fused to a broad postepigastric plate (longer than wider or nearly as long as wide) ( H. una sp. nov.,  H. brasiliana(Bristowe)and  H. honePlatnick, Berniker & Víquez, Figs 7G–H, 68G–H; Platnick et al., 2014, figs 85–86) as follows: from H. una sp. nov.by the genital duct narrow, situated on the anterior portion of the postepigastric plate (wide, almost reaching the posterior portioin of postepigastric plate in H. una sp. nov.); from  H. brasilianaby the curved arms of T-shaped genitalic process (straight in  H. brasiliana) and from  H. honeby the procurved arms of T-shaped genitalic process (recurved in from  H. hone) ( Figs 62F–H).   Description. Male(PBI_OON 40585). Total length 1.69. CEPHALOTHORAX: Carapacedark red-brown, with  Coxapopha-like pattern, pars cephalicawith two posterior humps in lateral view, surface of elevated portion of pars cephalicasmooth, sides granulate, fovea absent ( Figs 61B–C). EyesALE circular, PME circular, PLE oval; posterior eye row recurved from above, procurved from front; ALE separated by more than their diameter, ALE-PLE separated by less than ALE radius, PME touching for less than half their length, PLE-PME separated by less than PME radius ( Fig. 61E). Sternumlonger than wide, orange-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow with rows of small pits, radial furrow opposite coxae III absent, surface finely reticulate, without pits, microsculpture absent ( Figs 61D, 62A). Mouthparts: Chelicerae distal region unmodified ( Fig. 61E). Labium anterior margin anteriorly projecting at middle, wider than long ( Fig. 63C). Endites with a median projection (mp), a P1 and a P2; mp short, directed anteriorly; P1 hornlike, tip flattened, situated posteriorly to P2, directed posteriorly to mp. P2 lamellar, bent downwards, situated anteriorly to P1 ( Figs 61F, 63B–C). ABDOMEN: dorsum soft portions pale orange. Book lung covers small, very narrow. Dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding. Postepigastric scutum orange-brown, almost semicircular, covering nearly full length of abdominal length ( Figs 61B,G). LEGS: pale orange. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments pale orange; embolus tip flattened, not bent upwards; conductor present, without projections, as long as embolus, tip flattened, its tip bent upwards at an angle of almost 45° ( Figs 61G–I, 63F–I).  Female(PBI_OON 46372). As in male except as noted. Total length 1.86. CEPHALOTHORAX: Carapacewithout any pattern, pars cephalicastrongly elevated in lateral view ( Fig. 62B). Mouthparts: Chelicerae, endites and labium orange-brown. Labium rectangular, anterior margin not indented at middle ( Fig. 62D). ABDOMEN: Dorsal scutum covering more than 3/4 of abdomen. Postepigastric scutum covering about 3/4 of abdominal length ( Figs 62A–B,F). GENITALIA: Ventral view: postepigastric plate tongue-shaped; postepigastric scape present; copulatory orifice slit shaped, situated on the anterior margin of postepigastric plate. Dorsal view: anterior genitalic process with small, procurved arms; genital duct coiled; the anterior uterine sclerite has a slit-shaped opening in anterior surface ( Figs 62G–H, 63J–L).  Other material examined.   Brazil. Rio Grande do Sul.  Santa Cruzdo Sul: Linha Nova( 29°38’19.70”S, 52°23’19.89”W) ,  Aug. 21, 1994, R.
