Galumna tetraporosa Ermilov, Martens & Tolstikov 2014

Measurements. Body length: 962 (holotype), 913–979 (two paratypes); notogaster width: 730 (holotype), 730–763 (two paratypes). Integument. Body color black to dark brown. Body surface smooth. Pteromorphs with poorly visible radiate wrinkles. Prodorsum. Rostrum with strong tooth (12–20). Rostral setae (ro, 53–65) setiform, barbed. Lamellar setae (le, 65–77) setiform, little thicker and less barbed than rostral setae. Interlamellar setae absent, represented alveolus. Bothridial setae (ss, 114–123) with long stalk and shorter, barbed clavate head. Exobothridial setae absent. Porose areas Ad present, elongate oval (24–32 × 12–16), but visible only in dissected specimen. Lamellar lines (L) curving backwards; sublamellar lines (S) parallel in basal part and divergent in medio-distal part to lamellar lines. Notogaster. Anterior notogastral margin not developed. Dorsophragmata (D) of medium size, elongated. Notogastral setae represented by 10 pairs of alveoli. Five pairs of small, rounded porose areas with distinct borders: Aa divided into two porose areas – smaller lateral (8–16) and larger medial (20–28); A1 (12–16) and A2 (16–28) located close to each other; A3 (24–36) usually largest. Alveoli la inserted posteriorly to Aa. Lyrifissures im located anteriorly or antero-laterally to A1. Opisthonotal gland openings (gla) located antero-laterally to A2. Median pore absent. Gnathosoma. Generally, morphology of subcapitulum, palps and chelicerae typical for most Galumnidae (for example, see Ermilov and Anichkin 2010, 2011; Ermilov et al. 2011). Subcapitulum little longer than wide (196 × 192). Subcapitular setae setiform, slightly barbed; a (32–36) longer, more barbed and thicker than m (24) and h (16–20). Two pairs of adoral setae (or1, or2, 20) setiform, barbed. Palps (143) with setation 0–2–1–3–9(+ω). Solenidion straight, thickened, blunt-ended, attached to eupathidium. Chelicerae (246) with two barbed setae; cha (94) longer than chb (53). Trägårdh’s organ distinct. Epimeral and lateral podosomal regions. Apodemes (1, 2, sejugal, 3) well visible. Four pairs of epimeral setae (1b, 3b, 4a, 4b) observed ventrally, all setiform, thin, smooth, similar in length (24–32). Discidia (dis) triangular, circumpedal carinae (cp) distinct. Anogenital region. Six pairs of genital setae (g1–g6, 24–28) setiform, thin, smooth. Anterior edge of genital figs with three setae. One pair of aggenital (ag), two pairs of anal (an1, an2) and three pairs of adanal (ad1–ad3) setae minute, similar in length (4). Adanal setae ad3 inserted laterally to adanal lyrifissures iad. Postanal porose area (Ap) elongated (36–49 × 8–12). Legs. Generally, morphology of leg segments, setae and solenidia typical for most Galumnidae (for example, see Ermilov and Anichkin 2010, 2011; Ermilov et al. 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.
