Trypanidius mimicavus sp. nov.

( Figs 7, 9 , 27 )

Male. Dark brown integument. Body covered with grayish-brown pubescence, except head which is covered with golden yellow pubescence; gray-whitish pubescence covers basal 3/4 of scape, two transverse bands in antennomeres 3–7, a transverse band at base of antennomeres 8–11, and basal third of scutellum; yellow-whitish pubescence covers most of pronotum and femora, is present as two transverse bands on tibiae (one at basal fourth and another in middle region), and covers tarsomeres 1 and 2; a spot of black pubescence on inner margin of upper eye lobes, on outer margin of base of anterolateral tubercles, in two parallel longitudinal bands (one on each side of pronotal disc), on margin of scutellum, in region of elytra around scutellum, in a longitudinal elytral spot near suture and posterior to centro-median crest, in a transversal band at end of first half of elytra, in a transversal band at beginning of second half of elytra, in a lateral spot near apex of elytra; whitish pubescence in a band around spot of black pubescence at end of first half of elytra, extending around centro-basal crest toward suture, in a transversal band in apical fourth of elytra that starts in lateral margin toward suture extending as a longitudinal spot to apex and covering ventral surface. Apical region of scape, pedicel and antennomeres 3–11, elytra and tibiae covered with long, semierect and sparse setae.

Frons flat, lower eye lobes as large as genae, with two erect setae on inner margin. Antennae long, exceeding elytral apices at antennomeres 8 or 9; scape as long as antennomere 3.

Prothorax 1.5 times wider than long, with punctures restricted to anterior and posterior margins, with four tubercles: two lateral post-median with acute apex, and two anterolateral with obtuse apex; pronotal disc with three elevations: one post-median less prominent and two in median line more prominent, separated by slight central depression. Scutellum with rounded apex. Prosternal process two times narrower than procoxal cavity; mesosternal process as wide as mesocoxal cavity.

Elytra 4.5 times longer than prothorax; centro-basal crest near suture and longitudinal carinae strongly marked; apex truncate.

Measurements (mm). (Holotype / Paratype). Total length: 18.5/19.7; prothorax length: 2.8/3.1; prothorax width: 5.0/5.3; elytral length: 12.5/13.9; humeral width: 6.5/7.3.

Type material. Holotype male, BOLIVIA, Santa Cruz: Manuel María Caballero, 1.II.1993, Fray Andrez Langer leg. Paratype female, BOLIVIA, Santa Cruz: Manuel María Caballero, 1 exe. 1.II.1993, Fray Andrez Langer leg.; All in the MNRJ collection.

Etymology. The specific epithet is a posthumous homage to the first author’s grandfather. It is related to “vô mimica” in Latin, which was his nickname.

Comments. Trypanidius mimicavus sp. nov. 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.
