Plusiocampa (Plusiocampa) aff. dublanskii sp. nov.

Fig. 49–50

Material examined WESTERN CAUCASUS • 1 ♂; Abkhazia , Ochamchira District , near Otap Village, Abrskila Cave; 9 Sep. 2014; I.S. Turbanov leg.; ZMMU.

Remarks

Body length 2.8 mm. It shows some differences from the type form in the number of macrosetae on the pronotum (1+2 la 2,3), metanotum (1+1 la), urotergite IV (without la macrosetae), urotergite V (without la and 1+1 post 1), urotergite VI (1+1 la, 2+2 post 1,2), urotergite VII (2+2 la 2,3, 2+2 post 1,2), urotergite VIII (4+4 post) and abdominal segment IX (7+7 post).

Phyletic affinities, habitat and distribution

Among the described species of Plusiocampa s. str., P. (P.) bulgarica , P (P.) elongata , P. (P.) vodniensis and P. (P.) beroni from the Balkan karst region ( Condé 1954a; Bareth & Condé 2001; Sendra et al. 2012b), P. (P.) strouhali , P. (P.) caprai , P. (P.) grandii and P. (P.) hoelzeli from the Alps ( Condé 1954a; Neuherz 1984) and P. (P.) fagei from caves on Mallorca ( Condé 1955b) share two important taxonomic characters with P. (P.) dublanskii sp. nov.: the distinctly unequal claws with large lateral crests and an evident backward overhang on the posterior claw, and the presence of medial posterior macrosetae on the mesonotum and metanotum. Nonetheless, the absence of ventral tibial macrosetae or the extremely unequal claws with unequal lateral pretarsal processes suggest a completely different relationship with the unclear subgenus Venetocampa from the Veneto region, northern Italian Peninsula. These new troglomorphic taxa live in two separated karst regions in the north (Crimea) and the east (Western Caucasus) of the Black Sea. The important differences between the two studied specimens are remarkable, in particular the number and distribution of the macrosetae on the urotergites and abdominal segment, something that should be reviewed in the future with further samples.
