Muisca irrorata (GORHAM, 1877) (Figs 27, 54, 94, 102, 129)

Pelonium irroratum, GORHAM, 1877: 422. Lectotype: Gender not known. Here designated. Amazon, Bates (BMNH). Paralectotypes: 2 specimens. Amazon, Bates (one specimen severely damaged) (MNHN) Gorham’s description provides evidence that he examined more than one specimen, but he did not specify which one should be the name barer of this nominal species. Therefore, I invoke Recommendation 73F of the ICZN (1999) and designate a lectotype for this nominal species. Brazil, CORPORAAL 1950: 281.

D i a g n o s i s: The extraordinarily stout setae on the elytral disc and the subovoid hindbody will distinguish the members of this species from congeners.

R e d e s c r i p t i o n: Size: Length 5.8 mm; width 3.0 mm. Form: As in Fig. 129. Color: Mostly testaceous, capitulum and pterothorax black, and elytra infuscated near mesoscutellum, elytral asetiferous punctations fuscous. Head: Funicular antennomeres subfiliform, capitulum longer than combined length of funicular antennomeres, capitular antennomeres 9 and 10 triangular (Fig. 27), antennomere 11 obovate; frons narrower than width of eye (EW/FW 32/25). Thorax: Pronotum (Fig. 54) quadrate (PW/PL 95/95), side margin with slightly developed tubercle, disc coarsely punctate; elytra subovoid, elytral asetiferous punctation randomly distributed, broadly pigmented, and extend to elytral apical 4/5 th (EL/EW 220/95). Abdomen: Male 6 th visible sternite slightly concave along distal margin; aedeagus, phallic apex as in Fig. 102.

V a r i a t i o n: Size: Length 4.0- 5.5 mm; width 2.0- 2.8 mm. In one specimen, the elytral disc is more infuscated.

N a t u r a l h i s t o r y: The specimen from Bolivia was collected in October, at

370 m.

D i s t r i b u t i o n (Fig. 94): In addition to the 3 types, I examined 6 specimens: Bolivia: Departamento de Santa Cruz, 3.7 km SSE, Buena Vista, Hotel Flora & Fauna, 17°29. 949'S 63°33.152'W, tropical transition forest, M. C. Thomas & B. K. Dozier ; Poterillo del Guenda, 17°40'S 53°27' W, Provincia Andres Ibañes, 16-22-X- 2006, 370 m, Wappes, Nearns & Eya. Brazil: Estado do Amazonas, Amazonas ; Estado do Pará, Santarém. Specimens are deposited in ACMT, BMNH, MNHN, and WOPC .
