coxae indistinct. Mesosternal process very narrow. Mid and hind tibiae with short spur. Segment 1 of hind legs as long as two next segments together. Claws with sharp tooth. Aedeagus very complicate. Type species - Martinella merkli sp. n. Remarks - Differs from Agelastica and Calomicrus by unmarginate anterior border of prothorax, impressions near its anterior angles and very complicate structure of aedeagus. This genus seems to be very near to Hesperopenna L. MEDVEDEV et DANG DAP, 1981, but differs by quite different pubescence of elytra. This genus is dedicated to the memory of Dr. MARTIN JACOBY.
