Descriptive notes. Length of adults 4.5–10.0 mm, width.0.8–1.0 mm, with 23–43 podous + 3–1 apodous segments + telson, regardless of sex. Length to width ratio (except for smallest juveniles)> 8:1.
Live coloration uniformly red-brown to yellow, alcohol material usually somewhat faded (Fig. 4). Body only moderately flattened dorsoventrally, vermiform, regularly and modestly broadened until segment 4, similarly regularly and modestly narrowing towards telson on last 3 segments. Head small, subtriangular, only slightly narrower than collum and longer than broad, labrum broadly and regularly rounded, without a rostrum (Fig. 4 A, C). Ocelli absent. Antennae short, C-shaped, strongly clavate; antennomere 6 largest (Figs 4 A, 5A).
Collum ovoid, paraterga small, broadly rounded, dorsal surface with two transverse rows of 2+2 large, rounded tubercles. Following paraterga much larger, mostly set at about half of body height, broadly rounded and obtuseangled anteriorly, more narrowly rounded and acute-angled posteriorly, somewhat drawn behind tergal margin only in penultimate segment (Fig. 4). Each metatergum likewise clearly domed and with two transverse rows of 2+2 (segments 2–4) or 3+3 (all following segments before telson) large, rounded tubercles. Tegument extremely densely micro-hirsute and dull all over. Ozopores lateral, small, inconspicuous, lying at bottom of a small incision at about half of paratergal length, starting with segment 5. Telson coniform, completely exposed in dorsal view (Fig. 4 A, F).
Sterna large, but coxae almost in touch medially, mostly divided by a small, but evident, elongated elevation (Fig. 4 E). Legs 6-segmented. Male coxa 2 with a short, tube-shaped, simple, basal gonapophysis directed caudomesad. Claws usually simple, only a few anteriormost ones each with a minute accessory claw at base. Coxal sacks starting with leg 3.
Anterior gonopods (Fig. 5 B, C) plate-shaped, 6-segmented, strongly incrassate and stout. Posterior gonopods (Fig. 5 D) 7-segmented, much slenderer, tarsus longest, with a long, midway, spiniform filament and a slightly expanded tip.
Remarks. This species, originally described from the Hyrcan Nature Reserve in SE Azerbaijan (Golovatch 1980), seems to be endemic to Hyrcania within both the Republic of Azerbaijan’s southeastern part and northwestern Iran (Golovatch 1980, 1981).
