française d’Entomologie (N.S.), 29(1):43–44, fig. 25 (spermatheca).
A small to moderate-sized, dark orangish to reddish-castaneous species; described from female. Female: dorsal surfaces dull granulate with pronotal punctures very close and deep; elytron duller on inner disc with moderately deep punctures, discal side and apex with interspaces somewhat smoother; elytron additionally with prominent costae along side and preapex, the side sinuately narrowed to costate apex (in dorsal view). Dorsal vestiture setose and erect. Abdominal ventrite 1 (in oblique ventral view) convexly inclined to metasternum on basal ¾ and rather sharply bent to plane of remaining ventrites on apical ¼.
Male (nov.). Unlike female in lacking elytral costae and having a smoother, shinier and more uniform punctate surface; elytral side rather evenly narrowed to rounded preapex. Dorsal coloration orange-fulvous but marked with dark fuscous on inner basal quadrant of elytral disc, this mark appearing as a long triangle over both elytra. Dorsal surfaces lustrous and rather closely and deeply punctate. Abdominal ventrite 1 with surface uniformly and gradually inclined to metasternum. Genitalia: aedeagus extremely long and slender before briefly expanded apex; apex as in Fig. 3c. Measurements: Body length
2.9 mm
; body breadth
1.25 mm
; head breadth 86 cmm; interantennal space 28 cmm; interocular space 50 cmm; eye 26 cmm; gena 14 cmm; pronotal length 92 cmm; pronotal breadth 100 cmm; elytral length
2.2 mm
.
Variation.
Males: about 60% have the dorsum rather evenly orange-fulvous without strong fuscescent markings on the inner basal part of elytral disc.

Remarks.
This species differs from congeners by having the metafemur sub-clavate to clavate with metatibia correspondingly sinuate. The female is distinctive with the arrangement of elytral costae; the male has a shape resembling
T. sagittarii
,
n. sp.
but differs in having heavier, deeper punctures dorsally.
