Opitz, Pitz Pinola Weston, 2018, Classification, Natural History, and Evolution of the Subfamily Peloniinae O (Coleoptera: Cleroidea: Cleridae). Part IX. Taxonomic revision of the New World genus Muisca S, Linzer biologische Beiträge 50 (1), pp. 587-653 : 602

Muisca insigna ( CHEVROLAT, 1874) ( Figs 24 , 48, 93, 99, 126)

Pelonium insigne CHEVROLAT, 1874: 326. Lectotype: Gender not known. Here designated. Brazilia ( Brazil) (MNHN). CORPORAAL 1950: 281. 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.

Pelonium quadrifoveolatum SCHENKLING, 1906: 313. nov.syn. Lectotype. ♀. Here designated. Brazil, Jatahi (Jatai Goias) (SDEI). CORPORAAL 1950: 283. Paralectotype: 1 specimen from Brazil, Jatai Goias (SDEI). In his description Schenkling indicates that there was more than one specimen available to him, but he did not tag one of these to be the name barer of this nominal species. Therefore, I invoke Recommendation 73F of the ICZN (1999) and designate a lectotype.

D i a g n o s i s: The members of this species resemble superficially those of M. dilatata , but M. insigna specimens differ in that their sutural margin near the mesoscutellum is pale and the elytral asetiferous punctures extend beyond elytral basal 1/2.

R e d e s c r i p t i o n: Size: Length 9.0 mm; width 4.0 mm. Form: As in Fig. 126 . Color: Maxillae, labium, and antennae castaneous, mandibles labrum and clypeus brown; cranium mostly castaneous, with black mark on upper frons and behind eyes; pronotal disc with black circle bordered by white setae; elytral disc broadly dark brown behind humerus, brown area with a bluish luster, disc with a white oblique line anteriorly contiguous with sutural margin and posteriorly flares to broad white region on elytral apical third, light and dark brown marking near posterior region of sutural margin. Head: Funicular antennomeres subtriangular, 5 th funicular antennomere expanded, capitular antennomeres 9 and 10 triangular ( Fig. 24 ), anterior margins slightly concave, antennomere 11 obovate; frons narrower than width of eye (EW/FW 40/35). Thorax: Pronotum (Fig. 48) oblong (PW/PL 95/130), side margin with well-developed primary and secondary tubercles, disc coarsely punctate at sides, 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 (EL/EW 370/112). Abdomen: Male 6 th visible sternite not concave distally; aedeagus, phallobasic lobes minute, phallus slender, apex minute and digitiform ( Fig. 99 ), phallic plates very narrow and undulate near apex.

V a r i a t i o n: Size: Length 5.5-9.0 mm; width 2.5-4.0 mm. Other than body size, the available specimens are quite homogeneous.

N a t u r a l h i s t o r y: A specimen was collected in November.

D i s t r i b u t i o n ( Fig.93 ): In addition to the lectotype, I examined 6 specimens: Brazil: Estado do São Paulo, Barueri , XI-1966, K. Lenke ; Estado do Goiás, Goyaz (Goiás), Rio Verde ; Jatai Goiás. Specimens are deposited in CMNH, MNHN, SDEI, and WOPC.
