Genus Caucasominorus gen. nov.

Diagnosis. Differs from the other Caucasian anthroleucosomatids by the presence of one, two or several knife-like lobes on the coxal processes of the posterior gonopods.

Etymology. The new genus is named after its presence only in the Lesser Caucasus (Caucasus Minor). The name is a masculine noun.

Description. Body length 8–10 mm in males, 8.5–12 mm in females; number of body segments 31 in adults (including telson). Body pigmented. Head slightly concave in males. Antennae and walking legs normal. Lateral keels like lateral swellings. Macrochaetae relatively long, trichoid. Leg-pairs 3–7 in males enlarged. Male leg-pair 7 with a posterior coxal horn. Leg-pairs 10 and 11 in males with coxal glands. Male leg-pair 11 with a posterior coxal horn.

Anterior gonopods with a medial, small, hairy, sternal sac (ss) on anterior side of sternal plate (sp). Coxal processes (cp) wide, shield-like, connected to each other by posterior lamellae (pl), the latter forming a posterior projection (ppr). Posteriorly, two more lamellae can be seen on coxal processes, a mesal (ml) and a lateral (ll) lamella, as well as transverse rows of setae (rs), setose (sls) and wing-like (ws) structures.

Posterior gonopods with completely divided coxites (c). Telopodites (t) small, present on posterolateral sides. Coxal processes (cp) with one, two or several knife-like lobes (ks). Coxal vesicles (cv) present on anteromesal sides.

Distribution. Armenia, Azerbaijan ( Fig. 167 View FIGURE 167 , triangles).
