Tetrabothrus femoralis Pace 2014, nov.sp

Tetrabothrus femoralis nov.sp. (Figs 25 and 120-122) T y p e m a t e r i a l Holotype, Sabah, Danum Valley, B.R.L., f.i.t., 14-16.II.2007, G. de Rougemont leg. (CROU). Paratypes: 5 exx., same provenance as the holotype (CROU, MSNV). D e s c r i p t i o n: Length 5.5-5.9 mm. Body shiny, reddish, antennae reddish, legs yellowish-red with reddish-brown knees with basal ¾ of the femora pale yellow. Second antennomere shorter than the first, third longer than the second, fourth to tenth strongly transverse. Eyes shorter than the postocular region in dorsal view. Body devoid of reticulation. Puncturation of head and pronotum fine, absent on the longitudinal median band of both. Granulation of the elytra fine, very superficial and little evident. Four basal sulci of the free abdominal tergites deep. Aedeagus: Figs, 120-121; spermatheca: 122. C o m p a r a t i v e n o t e s: The aedeagus of this new species is more similar to that of T. indicus CAMERON, 1939 from Bengal, than to that T. borneensis CAMERON, 1943 from Borneo, of which I have seen specimens of the type series. The new species differs from T. indicus in the apex of the aedeagus, which is very narrow in ventral view (less narrow in T. indicus), in the distance between the "crista apicalis" and bottom of the curved preapical portion which measures 0.1 mm, (0.05 mm in T. indicus). The internal sclerotised piece of the aedeagus of the new species is less strong than that of T. indicus. The male holotype of T. indicus is labelled "Samsing, 1800, Kalimpong, Bengal, XII.1933, Balwant Singh, in soil under elephant dung, Tetrabothrus indicus Cam., Type."(MHNL). E t y m o l o g y: The pale yellow colour of the basal ¾ of the femora suggested the name of the new species.
