Genus Caucaseuma Strasser, 1970 View in CoL

Diagnosis. Differs from the obviously most similar genus Paranotosoma gen. nov. by the presence of two flagelliform coxal processes on the posterior gonopods, from the genus Heterocaucaseuma gen. nov. by the presence of anterior shield-like processes of the anterior gonopods.

Description. Body length 8–20 mm; number of body segments 28 or 30 in adults (including telson). Epigean species with pigmented body, vs. species known only from caves being yellowish white or with bodies with reduced pigmentation. Head without frontal depression in males. Antennae and walking legs normal; somewhat elongated in cave-dwelling species. Lateral keels better developed in species known in caves, like lateral swellings. Macrochaetae relatively long to long, trichoid. Leg-pairs 3–7 in males enlarged, with or without peculiarities on leg-pair 7. Leg-pairs 10 and 11 in males with coxal glands, with neither any coxal horns nor processes.

Anterior gonopods with a medial, subtriangular and hairy sternal sac (ss) arising from sternal plate (sp) on anterior side. Coxal processes divided into anterior and posterior parts. Anterior coxal processes (cp) wide and shield-like, posterior one (pp) mainly in the form of a complex lever.

Posterior gonopods with completely divided coxites (c). Posterolateral sides with small telopodites (t). Coxal vesicles (cv) present on anterior side. Both coxites bearing a pair of whip-like coxal processes (cp).
