Taophila nigrans Jolivet et al. (2007) Revue 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.

Parts of longer IAC series for deposit in BPBM, ISNB, JOLIVET, MNHN, NMNH, ONNC, and SMTD.
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.
