Material examined. 3 males , 9 females ( ZMUM ), ABKHAZIA , Sukhumi Distr. , Yashtukha , tree nursery, 29.III.1986 , leg. A. Markossian ; 2 subadult females ( ZMUM ), Sukhumi Botanical Garden , litter, 2.X.1978 ; 1 male (slide only) ( ZMUM ), same locality 9.X.1978 ; all leg. S. Golovatch. Descriptive notes. Length ca 8 – 16 mm , width of midbody metazonae 1.5 – 2.0 mm (male, female), metazonite to prozonite width ratio <1.6 ( Fig. 5A ). Live coloration usually uniformly light brown to brown, about same as in alcohol ( Fig. 5A ). All characters as in P. abchasius ( Fig. 5 ), except as follows. Collum much narrower than head, transversely oval in shape ( Fig. 5A ). Paraterga not upturned, subhorizontal, much more strongly rounded laterally, at least until segment 9 obtuse-angled and drawn behind rear tergal margin starting with segment 14 or 15 ( Fig. 5A ). Male prefemora strongly bulging laterad ( Fig. 5B ). Gonopod ( Fig. 5C ) with a stout and stump-shaped endomere ( en ) and only a slightly curved and apically strongly bifid exomere ( ex ). Remarks. The only previous record in the region ( Talikadze 1984 ) concerned “ Abkhazia ”, without a precise locality. This eastern Mediterranean species/subspecies is quite common in the adjacent Crimea , apparently being introduced to the Caucasus. New illustrations are provided to facilitate recognition ( Fig. 5 ).
