C o m m e n t: Myllaena caucasica was originally described based on an unspecified number of syntypes collected "beim Aul Kasbek im Moose einer Quelle" ( EPPELSHEIM 1880). Four syntypes were located in the collections of NHMW. A male in good condition is designated as the lectotype. The species was subsequently reported from East Turkey (Bitlis) by SCHEERPELTZ (1958). The primary sexual characters were previously unknown.

D i a g n o s i s: This species is highly similar to M. intermedia , as is shown also by the fact that a non-type specimen identified as M. caucasica by Eppelsheim himself proved to be M. intermedia . Aside from the completely different primary sexual characters, M. c aucasica is distinguished from M. intermedia only by shorter elytra ( M. caucasica : elytra approximately 0.65 times as long as pronotum; M. intermedia : elytra approximately 0.8 times as long as pronotum), hind wings of reduced length ( M. intermedia : hind wings fully developed), and a relatively larger pronotum. The aedeagus and spermatheca are illustrated in Figs 48-55 View Figs 48-56 . Among West Palaearctic Myllaena species, M. caucasica is most similar to M. hyperborea STRAND, 1934, both in external and the male and female primary sexual characters. The aedeagus of M. caucasica is readily distinguished from that of M. hyperborea by distinctly larger size alone. For an illustration of the median lobe of the aedeagus of M. hyperborea see Fig. 56.

D i s t r i b u t i o n: Myllaena caucasica is currently known from the Russian part of the Greater Caucasus (first record from Russia), Georgia, Turkey westwards to Amasya in the north and Kahramanmaraş in the south, Armenia (first record), and Nagorno- Karabakh (first record) ( Map 2 View Map 2 ).
