Fig. 28View FIGURE 28, Map 3

Material examined. Holotype male ( MIZW), GEORGIA, Ajaria, Zelenyi Mys near Batumi, Botanical Garden, 30.X. – 6.XI.1963, leg. B. Pisarski  . Paratypes: 3 males, 2 fragments (MIZW), 1 male ( ZMUM p3035), same data, together with holotype. Non-type   : 1 female ( ZMUM p3036), Ajaria, Khulo Distr. , 3 km W of Danisparauli, deciduous forest, litter, 10.X.1981, leg. S. Golovatch. 

Diagnosis. Differs from B. kalischewskyi  , the only consubgener remaining accepted, in the particularly small body, the nearly fully obliterate metatergal sculpture, the absence of sphaerotrichomes, and the presence of only a single apical tooth on the gonopod exomere; from B. simplex  sp. n. primarily by the particularly slender male legs, the narrower paraterga and the considerably shorter exomere of the gonopod.

Name. To commemorate the late Dr. Eristo Sh. Kvavadze, a prominent specialist in the earthworms of the Caucasus and a close friend of the first author.

Description. Length 5 – 6 mm, width of midbody metazonae 0.65 – 0.7 mm (male), metazonite to prozonite width ratio ca 1.3 ( Fig. 26AView FIGURE 26). Coloration uniformly pallid to light brown.

All characters as in B. assimilis  ( Fig. 28View FIGURE 28), except as follows. In width, collum <2 = 3 <4 <head = 5. Paraterga poorly developed, their fore margins and anterolateral corner largely broadly and regularly rounded, not angular; caudolateral corner mostly acute-angled, pointed or nearly pointed and drawn behind rear tergal margin only in segments 17 and 18 ( Fig. 28AView FIGURE 28). Tergal setae mostly very short and subbacilliform. Metatergal sculpture nearly fully obliterated. Male prefemora not bulging laterad, slender; sphaerotrichomes wanting ( Fig. 28BView FIGURE 28). Gonopod ( Fig. 28C – 28DView FIGURE 28) bipartite, stout, endomere (en) typically bifid and partly pilose, but exomere (ex) long, with only a single, apical, rounded tooth (e).
