Habitus, size and coloration of Theratta species resemble those of the widespread introduced tramp species Rhinotus purpureus . Distinguished from the three other genera of the tribe Rhinotini by the bifurcation of the podomere II of anterior gonopod into a mesal process on the posterior side, with a furrow between the mesal process and the main part of the podomere II ( Figs 5D–F ); modification of the anterior side of anterior gonopod into a lamellar process ( Fig. 6C ); absence of conical elevations on the sternite of the posterior gonopod ( Figs 6I, J ), as found in the genera Rhinotus (see Wesener 2014) and Siphonoconus (see Attems 1931 ). Eyes consisting of a single pair of ommatidia ( Fig. 3A ); head with a pair of macrosetae anterior to the ommatidia ( Figs 2B , 3A ); tarsal claw with a thin paronychium extending beyond the claw, curved and bulged distally ( Fig. 4F ); tergites with groove-like striae; anterior margin of metazonites with a distinct row of striae ( Fig. 4A ); lateral margin of the pleurite covered with setae ( Fig. 3H ). Etymology. Genus epithet, Theratta , noun, feminine. Millipedes are called ‘ Theratta ’ in Malayalam, the language spoken in the Indian province ( Kerala ) of the type species.
