Muisca anachyma OPITZ nov.sp. (Figs 33, 65, 96, 139)

Holotype: ♂. COLOM. Magd., 7000', San Lorenzo, 41 km S Sta. Marta, V-2-1973, Campbell & Howden (CNCI).

D i a g n o s i s: Muisca anachyma specimens may be distinguished from those of its sister species, M. mestolinea, by coloration of the elytral disc. In M. anachyma specimens, the elytral disc is nearly uniformly light castaneous, each elytron with a faint indication of 3 punctiform infuscations. In M. mestolinea specimens, the elytral disc shows 4 dark brown lines. Also, the sutural margin is castaneous in specimens of M. anachyma . The margin is dark brown in specimens of M. mestolinea .

D e s c r i p t i o n: Size: Length 5.5 mm; width 2.3 mm. Form: As in Fig. 139. Color: Mostly light castaneous; each elytron with 3 obliquely positioned faint spots behind middle. Head: Funicular antennomeres filiform, capitulum shorter than combined length of funicular antennomeres, capitular antennomeres 9 and 10 long-triangular (Fig. 23), antennomere 11 obovate; frons wider than width of eye (EW /FW 25/40). Thorax: Pronotum (Fig. 65) quadrate (PW /PL 110/110), side margin with well-developed tubercle, punctation distributed throughout disc; elytral asetiferous punctation minute, interstitial spaces wide, substriate but diminished to elytral apex (EL /EW 340/95). Abdomen: Pygidium subquadrate, posterior margin concave.

N a t u r a l h i s t o r y: The holotype was collected during May, at 2134 m. E t y m o l o g y: The specific epithet, anachyma, is a Greek adjective that means "expanse". The name refers to the comparatively large width of the elytral interstitial spaces.

D i s t r i b u t i o n (Fig.96): This species is known from Colombia.
