Material examined. BOLIVIA, Santa Cruz: Caballero [Manuel María Caballero], Yungas de S.J.P, 4 males, 1 female, 1.II.1993, Fray Andr é s Langer leg. (3 males, FSCA; 1 male, 1 female, MZSP)

Remarks. According to Carelli et al. (2013): “ Trypanidius mimicavus new species differs from the other species of the genus mainly by the presence of four anterolateral tubercles on the prothorax, and by the long and semierect setae on many parts of the body. All other Trypanidius species have the sides of prothorax with only two tubercles, and the body without long and semierect setae.” Trypanidius mimicavus cannot belong to Trypanidius because it has erect setae on the elytra (absent in Trypanidius ) and the apical margin of ventrite 5 is concave, making the outer angles spiniform (rounded in Trypanidius ). Trypanidius mimicavus belongs to Carphina Bates, 1872 . The holotype male and the paratype female (the latter is the specimen illustrated in the original description) were lost during the fire that destroyed the MNRJ. These two specimens had the same data as the specimens examined by us in this work. We think that a designation of a neotype is not necessary because the species can be easily identified and separated from the other species of Carphina . Even so, we redescribed the species so that there are no future doubts.

Carphina mimicavus is similar to C. elliptica (Germar, 1823) ( Fig. 8–14 ) but differs as follows: scape without dark ring just after middle ( Fig. 1–4, 6–7 ); genae longer than lower eye lobe ( Fig. 4 ); anterolateral tubercles on the pronotum moderately elevated ( Fig. 5 ); dark pubescent bands on the pronotum straight and widened toward posterior margin ( Fig. 1, 6 ); and metaventrite in males without dense bristly pubescence ( Fig. 2–3 ). In C. elliptica , the scape has a dark ring just after middle ( Fig. 8, 10–11, 13–14 ), genae shorter than lower eye lobe ( Fig. 11 ), anterolateral tubercles on the pronotum are slightly distinct ( Fig. 12 ), dark pubescent bands on the pronotum arched and not widened toward posterior margin ( Fig. 8, 13 ), and metaventrite in males with dense bristly pubescence ( Fig. 9–10 ).

The specific epithet “mimicavus ” is a noun phrase in apposition (See Carelli et al. 2013: 257), therefore, it cannot be changed to agree in gender with the generic name.
