Muisca dilatata ( CHEVROLAT, 1876) ( Figs 14 , 47, 93, 98, 125)

Pelonium dilatata CHEVROLAT, 1876: 39. Lectotype: ♀. Here designated. Brazilia ( Brazil), Santa Rita, VIII, D. Sahlberg (MNHN). CORPORAAL 1950: 280. CHEVROLAT did not specify in his description the number of specimens before him while preparing his description. Therefore, I invoke Recommendation 73F of the ICZN (1999) and designate a lectotype for this nominal species.

D i a g n o s i s: The members of this species resemble superficially those of M. insigna , but M. dilatata specimens differ in that their sutural margin near the mesoscutellum is brown and the elytral asetiferous punctures do not extend beyond elytral basal ½.

R e d e s c r i p t i o n: Size: Length 8.0 mm; width 3.0 mm. Form: As in Fig. 125 . Color: Mouthparts, clypeus, and antennae brown, mandibular apices black; cranium mostly brown, frons infuscated; pronotal periphery black, submetalic, disc at center brown; elytral disc broadly brown behind humerus, disc with a white oblique line anteriorly contiguous with sutural margin and posteriorly flares to broad white region on elytral apical third, small brown fleck in posterior region of sutural margin. Head: Funicular antennomeres subtriangular, 5 th funicular antennomere expanded laterally, capitular antennomeres 9 and 10 triangular ( Fig. 14 ), with anterior margins slightly concave, antennomere 11 obovate; frons narrower than width of eye (EW/FW 35/26). Thorax: Pronotum (Fig. 47) oblong (PW/PL 100/110), side margin with well-developed primary and secondary tubercles, widely subglabrous at middle, disc with tumescenses; elytral asetiferous punctation subseriate, at sides extend to elytral apical 3/4 th, punctures absent near sutural margin, except at anterior 1/5 th (EL/EW 315/93). Abdomen: Male 6 th visible sternite not concave distally; aedeagus, phallobasic lobes minute, phallobasic struts absent, phallus slender, apex minute and digitiform ( Fig. 98 ), phallic plates very narrow and undulate near apex.

V a r i a t i o n: Size: Length 6.0-10.0 mm; width 2.5-4.5 mm. Except for body size, the available specimens are quite homogeneous.

N a t u r a l h i s t o r y: Specimens were collected in September through December, at altitudes that ranges from 370 to 800 m. Some specimens were collected with a black light set in a disturbed tropical transitional forest. D i s t r i b u t i o n ( Fig. 93 ): In addition to the lectotype, I examined 130 specimens: Bolivia:
