Lectotype. ♂. Here designated. Brasilien (Brazil), Nova Teutonia, Fritz Plaumann (MNHN) .

New Combination. CORPORAAL, 1950: 273 ( Platynoptera).

Paralectotypes: One specimen from Brazil, Bahia, Cachimbo, 1890, Ch Pujol (MNHN).

Diagnosis: Absence of protibial spines in specimens of Tarandocerus testaceiceps will distinguish the members of this species from congeners.

Description: Size: Length 12.0 mm; width 4.0 mm. Form: As in Fig. 172. Color: Cranium mostly flavotestaceous, black line behind eyes; pronotum mostly flavotestaceous, with two black lines on the pronotal disc; elytra bicolored, anterior half of disc flavotestaceous, posterior half black. Head: Antennal capitulum (Fig. 85) longer than combined length of scape, pedicel, and funicle, antennomeres 9 and 10 with collateral branch; antennal carina very prominent; EW/FW 23/28. Thorax: Pronotal anterior margin not projected at middle; side margin of disc slightly rounded at middle; PW/PL 75/80; elytra conspicuously flared; disc with 4 prominent discal carinae; EL/EW 330/90.
