Additional description, male topotype ♂ ( ISLA 12432). Body color: dorsal head, pronotum and abdomen uniformly dark yellowish brown and whitish ventrally, darker than in A. maya n. sp.

Thorax: pronotum slightly pubescent and more brownish compared to A. maya n. sp.; anterior, medial and posterior portion with less sclerotized regions (appearance of whitish spots) distributed along the sagittal axis in dorsal view ( Figs 32 and 33 View FIGURES 30–36 ); dorsal disk broader than long, lateral lobes rounded, anterior and posterior margins sub-straight, anterior margin with long bristles, posterior and lateral margins with possibly lost bristles in fixation ( Fig. 32 View FIGURES 30–36 ). Legs. In general, femur, tibia and tarsus pubescent; femur smaller than tibia in length (μ = 9.796 ± 1.476 mm; μ = 11.164 ± 1.603 mm, femur and tibia respectively, Leg III, n = 9) ( Figs 37–40 View FIGURES 37–40 ). Leg I ( Figs 39 and 40 View FIGURES 37–40 ): tibia armed with two same-sized ventral apical spurs, tympanum absent; first tarsomere ventrally serrated and twice longer than second and third together. Leg II ( Figs 39 and 40 View FIGURES 37–40 ): tibia armed with two same-sized ventral apical spurs ( Fig. 39 View FIGURES 37–40 ; ε and Fig. 40 View FIGURES 37–40 ; ζ); first tarsomere ventrally serrated and twice longer than the second and third together. Leg III: femur dilated; tibia serrulated, armed with four subapical spurs on outer side ( Fig. 37 View FIGURES 37–40 ; w, x, y, z), the distal being smaller ( Fig. 37 View FIGURES 37–40 , z), and three on inner side ( Fig. 38 View FIGURES 37–40 ; α, β, γ), three apical spurs on outer ( Fig. 37 View FIGURES 37–40 ; a, b, c) and four on the inner side ( Fig. 38 View FIGURES 37–40 ; d, e, f, g), the inner being the longest; first tarsomere about twice longer than the second and third together, armed with two apical spurs ( Figs 37 and 38 View FIGURES 37–40 ). Right Tegmen: absent ( Fig. 32 View FIGURES 30–36 ). Abdomen: cerci long and pubescent, mainly in the base ( Fig. 34 View FIGURES 30–36 ); sub-genital plate dark brown, wider than longer, spheroidal shape, convex distally (pers. obs. the shape of the structure was possibly damaged by fixation to ethanol and your bristles are lost) ( Figs 34 and 35 View FIGURES 30–36 ); supra-anal plate dark brown, quadrangular, pubescent, proximal margin V-shaped and with two lateral projections, lightly convex distally, with two distal-lateral globular projections with long bristles ( Figs 34 and 36 View FIGURES 30–36 ).
Male phallic sclerites ( ISLA 12431, Figs 24–28 View FIGURES 24–29 ). Pseudepiphallus: arm long and curved inward ( Fig. 25 View FIGURES 24–29 , Ps.arm); ventral projection reduced and globular shaped compared to A. maya n. sp.

( Figs 26 and 27 View FIGURES 24–29 , Ps.ms); paramere 1 well developed, cone shaped frontally and globular dorsally, with a band less sclerotized, forming a smaller portion dorsally and a larger portion ventrally ( Figs 25–27 View FIGURES 24–29 , Ps.P1); paramere 2 reduced and undeveloped, connected with Ps.P1, flattened and projecting towards C-sclerite basal plate (C-bp) ( Figs 25–27 View FIGURES 24–29 , Ps.P2); A sclerite well sclerotized, starting from the Ps.arm, thin and involving the paramere 1 ( Figs 25, 26 and 28 View FIGURES 24–29 , A). C-sclerite: in general is the most sclerotized part of the sclerite; ventral projection globular ( Fig. 26 View FIGURES 24–29 , C-vp); laterobasal spine very reduced and underdeveloped compared to A. maya n. sp. ( Figs 24 and 25, 27 and 28 View FIGURES 24–29 , C-lbs); basal plate less broad compared to A. maya n. sp., slightly concave medially, inclining inward and almost reaching the Ps.P2 ( Figs 25 and 26 View FIGURES 24–29 , C-bp). Ectophallic invagination: arc developed, straight at the upper and curved in central part ( Fig. 24 View FIGURES 24–29 , Ect.Arc); lateral bars elongated and projected inwards ( Fig. 24 View FIGURES 24–29 , Ect.lb); apodemes developed, flatted, dilated and projected outwards of the sclerite, at dorsal and ventral view, with its distal portion rounded and degree of opening is bigger compared to Arachnopsita maya n. sp. ( Figs 25 and 28 View FIGURES 24–29 , Ect.ap); Endophallus: endophallic fold small, forming V-shaped and narrower compared to Arachnopsita maya n. sp.

Female ( ISLA 12422): same appearance in relation to males, body size slightly bigger than male (♀ µ = 18.097 ± 1.291 mm, n = 4); apterous; femur always smaller than tibia; sub-genital plate brown and pubescent, short, Vshaped, distal margin lightly forked compared to A. maya n. sp. ( Fig. 41 View FIGURES 41–45 ); supra-anal plate whitish with dark spots and pubescent, distal margin rounded with long bristles, proximal with two small projections ( Fig. 42 View FIGURES 41–45 ); ovipositor dark yellowish brown, elongated, sword shaped, with a constriction near the apex, pointed apex ( Figs 43–45 View FIGURES 41–45 ). Female genitalia ( ISLA 12430, Fig. 29 View FIGURES 24–29 ). Copulatory papilla elongated, flat ventrally, lateral margins slightly bulging ventrally and dorsally, slightly narrow towards at apex ( Fig. 29 View FIGURES 24–29 , a and b); with the presence of a slightly convex bulge towards at base compared to A. maya n. sp., evident laterally ( Fig. 29 View FIGURES 24–29 , c).
