Body size 398–415 × 298–332. Lamellar lines short, almost straight. Prodorsal setae long, setiform; rostral and lamellar setae slightly barbed, interlamellar setae smooth. Sensilli with long stalk and shorter, lanceolate, indistinctly barbed head. Anterior notogastral margin weakly developed. Four pairs of porose areas rounded. Median pore and postanal porose area present.
Measurements. Body of medium size. Body length: 398 (holotype), 415 (paratype); notogaster width: 298 (holotype), 332 (paratype).
Integument. Body color yellowish-brown. Body surface smooth, but some transverse stria located posteriorly to the genital apertures. Pteromorphs with distinct radiate wrinkles.
Prodorsum. Rostrum widely rounded. Rostral (61–65) and lamellar (73–77) setae setiform, weakly barbed. Interlamellar setae (102–110) setiform, smooth. Sensilli (86–90) with long stalk and shorter, lanceolate, indistinctly barbed head. Exobothridial setae absent. Sublamellar lines distinct, typical for Galumna (Galumna): long, curving backwards. Lamellar lines (L) specific: rather short (not reaching the insertions of rostral setae), amost straight. One pair of porose areas Ad large, oval, located posterior to interlamellar setae.
Notogaster. Anterior notogastral margin weakly developed. Dorsophragmata (D) of medium size, elongate. Notogastral setae represented by 10 pairs of alveoli. Four pairs of porose areas round (Aa, A3, 18–20; A1, 16; A2, 10–12), with distinct borders. Alveoli of setae la inserted posteriorly to Aa. Lyrifissures im located anteriorly to A1. Opisthonotal gland openings (gla) poorly visible. Median pore represented as large alveolus, located in posterior part of notogaster between the virtual lines connecting A2–A2.
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 (16) thin, smooth.
Epimeral and lateral podosomal regions. Apodemes (1, 2 sejugal, 3) well visible. Four pairs of epimeral setae observed ventrally; 1a, 3b (14–16) longer than 4a, 4b (10–12), all thin, smooth. Discidia triangular, circumpedal carinae distinct.
Anogenital region. Six pairs of genital (g1–g2, 14–16; g3–g6, 10–12), one pair of aggenital (14–16), two pairs of anal (14–16) and three pairs of adanal (14–16) setae thin, smooth. Anterior edge of genital plates with three setae. Adanal setae ad3 inserted laterally to adanal lyrifissures iad. Postanal porose area (Ap) rounded (18–20).
Legs. Three claws 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). 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.
The holotype is deposited in the collection of the Zoological Institute of the Russian Academy of Sciences, St. Petersburg, Russia; paratype is deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.
The prefix para is Latin meaning “near” and refers the similarity between the new species and the species Galumna calcicola (Aoki & Hu, 1993).
Galumna (Galumna) paracalcicola sp. n. can be included in calcicola-group. Species of this group have the short (clearly not reaching the insertions of rostral setae), almost straight lamellar lines.
