Abstract

Two new species, Myllocerus vathalmalaensis sp. nov. and M. depressus sp. nov., are described from India. M. vathalmalaensis differs from M. lineaticollis (Boheman, 1842) in possessing a fine central carina on the impressed rostrum, the second funicle segment longer than the first one and tegmen without parameres. M. depressus differs from M. cardoni Marshall, 1916 by the dorsally depressed rostrum, which is longer than the head, a prothorax depressed and constricted near the posterior margin, the antennae and legs black in colour, the hind femora with a single spine and a spermatheca with curved nodulus.
