Pergalumna striatiprodorsum Ermilov, Alvarado-Rodríguez & Retana-Salazar 2014

Measurements. Body length: 697 (holotype, female), 630–697 (eight paratypes: five males and three females); notogaster width: 514 (holotype), 448–514 (eight paratypes). Integument. Body color brown to black-brown. Body surface, pteromorphs and subcapitular mentum with dense microgranules (their diameter up to 2). Surface of prodorsum with numerous longitudinal stria. Pteromorphs with poorly visible wrinkles. Prodorsum. Rostrum broadly rounded. Rostral (41–53), lamellar (57–69) and bothridial (106–114) setae setiform, barbed. Interlamellar setae short (12–16), setiform, slightly thickened, barbed. Exobothridial setae absent. Lamellar and sublamellar lines distinct, parallel, curving backwards. Insertions of lamellar setae distanced from the lamellar lines. Porose areas Ad elongate oval (20–28 × 4–8), located latero-posteriorly to interlamellar setae. Notogaster. Anterior notogastral margin not developed. Dorsophragmata of medium size. Notogastral setae represented by 10 pairs of alveoli. Three pairs of porose areas well visible, with distinct margins: Aa rounded (14–16) or oval, weakly transversally oriented (14–20 × 12–16), A1 oval, weakly elongated diagonally (24–41 × 12–20), A3 rounded (12–16 )or oval (12–16 × 10–12). Porose areas Aa located between notogastral alveoli la and lm, but clearly closer to lm. Median pore absent. All lyrifissures distinct; im located latero-anteriorly to A1. Opisthonotal gland openings located laterally to A1. Gnathosoma. Morphology of subcapitulum, palps and chelicerae typical for Pergalumna (see Engelbrecht 1972; Ermilov et al. 2010; Ermilov and Anichkin 2011). Subcapitulum longer than wide (155–159 × 131–143). Subcapitular setae setiform, slightly barbed; a (24) longer than m (16) and h (14–16). Two pairs of adoral setae (12–14) setiform, hook-like distally, barbed. Palps (123–127) with setation 0–2–1–3–9(+ω). Solenidion attached to eupathidium, both located on dorsal tubercle. Chelicerae (196–205) with two setiform, barbed setae; cha (53) longer than chb (32–36). Trägårdh’s organ distinct. Epimeral and lateral podosomal regions. Apodemes 1, 2, sejugal and 3 well visible. Six pairs of setiform epimeral setae observed; setal formula: 1–0–2–3. Setae 4a, 4b (6–8) thin, smooth, shorter than 3b (20–24) and 1b, 3c, 4c (32–36), slightly barbed. Pedotecta II scale-like, rounded in ventral view. Discidia pointly triangular. Circumpedal carinae distinct, directed posterior of setae 3b. Anogenital region. Six pairs of genital (g1, 16–18; g2, 12–14; g3–g6, 8–10), one pair of aggenital (6–8), two pairs of anal (6–8) and three pairs of adanal (6–8) setae setiform, thin, smooth. Anterior parts of genital figs with two setae. Adanal setae ad3 inserted laterally to lyrifissures iad. Postanal porose area present, elongate oval (20–28 × 6–8). Legs. Morphology of leg segments, setae and solenidia typical for Pergalumna (see Engelbrecht 1972; Ermilov et al. 2010; Ermilov and Anichkin 2011). Formulae of leg setation and solenidia: I (1–4–3–4–20) [1–2–2], II (1–4–3–4–15) [1–1–2], III (1–2–1–3–15) [1–1–0], IV (1–2–2–3–12) [0–1–0]; homology of setae and solenidia indicated in Table 1.
