Phlebonotus anomalus ( Saussure, 1863)

( Figs. 13 K, L, 15 E, 16 H, I)

Material. SOUTH INDIA, state Tamil Nadu, Coimbatore , September 1960, coll. P.S. Nathan— 1 female ( MMUM).

Description. The studied female is similar to that of T. porcellana , but can readily be distinguished from it by the following characters: the pronotum semicircular ( Fig. 16 I); the tegmina less sclerotized, the venation wellmarked, with whitish strips along veins ( Fig. 16 I); the wings strongly reduced.

Head slightly longer than wide ( Fig. 16 H); facial part with weak impression between antennal sockets; ocellar spots smaller, as compared to male of P. pallens ; distance between eyes 1.3 times of the eye length; distance between antennal sockets about 2.1 times of the scape length (0.9 mm); approximate length ratio of 3rd–5th segments of maxillary palps 1.1: 1: 1.3. Anterior margin of fore femur armed according to the type B, with 3 spines, including 1 apical one. Anal plate less protruded caudally and cerci shorter ( Fig. 13 K), as compared with T. porcellana . Genital plate with caudal margin widely rounded ( Fig. 13 L). Structures of ovipositor less sclerotized ( Fig. 15 E), as compared with T. porcellana . Basivalvulae in shape of two asymmetrical sclerites, more elongated ( Fig. 15 E, bsv.), as compared with T. porcellana . Apical parts of vestibular sclerite forked ( Fig. 15 E, vs.).

Measurements (mm). Head length: 3.6; head width: 3.3; pronotum length: 4.5; pronotum width: 8.4; tegmen length: 13.0; tegmen width (in place where CuP running into posterior margin of tegmen): 6.0.
