Allogalumna monodactyla Ermilov & Anichkin

Measurements. Small species. Body length: 188 (holotype), 180, 184 (two paratypes); notogaster width: 123 (holotype), 114, 118 (two paratypes). Integument. Body color yellowish-brown to brown. Body and legs covered by the microgranular cerotegument. Granules (up to 1) visible only under high magnification. Body surface smooth. Pteromorphs with distinct radiate wrinkles. Prodorsum. Rostrum widely rounded. Rostral (ro, 2), lamellar (le, 4) and interlamellar (in, 2) setae thin, smooth. Sensilli (ss, 24–28) with short stalk and well-developed disk-like head, having seven cilia (all inserted in one row) of medium size. Exobothridial setae absent. Sublamellar lines (S) distinct, typical for Allogalumna: long, curving backwards. Porose areas Ad not founded. Notogaster. Anterior notogastral margin not developed. Dorsophragmata absent. Notogastral setae represented by 10 pairs of alveoli. Four pairs of porose areas small, round (Aa, 4–6; A1–A3, 4), poorly visible, punctiform, without distinct borders. Alveoli of setae la inserted latero-posteriorly to Aa. Lyrifissures im located between lm and lp. Opisthonotal gland openings not evident. Median pore (mp) present in all specimens, located in centrodorsal part of notogaster between the virtual lines connecting lm and lm, lp and lp. Gnathosoma. Morphology of subcapitulum, palps and chelicerae typical for most Galumnidae (for example: Ermilov and Anichkin 2010, 2011a, 2013b; Ermilov et al. 2011, 2013a). Subcapitular setae h minute (4), thin, smooth. Epimeral and lateral podosomal regions. Apodemes (1, 2 sejugal, 3) well visible. Four pairs of epimeral setae observed ventrally; 1a, 3a, 3b, 4a short (4), thin, smooth. Discidia (dis) triangular, circumpedal carinae (cp) distinct. Anogenital region. Six pairs of genital (g1–g6), one pair of aggenital (ag), two pairs of anal (an1, an2) and three pairs of adanal (ad1–ad3) setae little differs in size, minute (3–4), thin, smooth. Anterior edge of genital plates with two setae. Adanal setae ad3 inserted laterally to adanal lyrifissures iad. Postanal porose area absent. Legs. Monodactylous; claw of each leg smooth. Morphology of leg segments, setae and solenidia typical for most Galumnidae (for example: Ermilov and Anichkin 2010, 2011a, 2013b; Ermilov et al. 2010, 2011), but solenidion of genua III weakly dilated in medial part. 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.

Single prime (’) marks setae on anterior and double prime (’’) setae on posterior side of the given leg segment. Parentheses refer to a pseudosymmetrical pair of setae.
