D i a g n o s i s: Within the M. testacea -group, each elytron shows an irregular fascia in specimens of M. agma and in those of M. nigrosignata . However, in M. agma specimens, this fascia is fragmented, which is not the case in M. nigrosignata specimens.

D e s c r i p t i o n: Size: Length 4.3 mm; width 2.0 mm. Form: As in Fig. 148. Color: Light testaceous, except each elytron with 2 black spots near the humeral angle and a black fragmented angular fascia at middle of disc. Head: Funicular antennomeres subfiliform, progressively more triangular toward capitulum, capitulum about as long as combined length of funicular antennomeres, capitular antennomeres 9 and 10 triangular (Fig. 35), antennomere 11 obovate; frons wider than width of eye (EW /FW 18/33). Thorax: Pronotum (Fig. 70) quadrate (PW /PL 75/75), side margin with well-developed tubercle, disc subglabrous at middle; elytral asetiferous punctation minute, striate to distal 2/3 rd (EL /EW 220/55). Abdomen: Pygidium subquadrate; posterior margin of 6 th visible sternite broadly concave; aedeagus long, phallic plates very narrow, phallic apex (Fig. 117) small, triangular.

V a r i a t i o n: Size: Length 4.3-6.0 mm; width 2.0- 2.3 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: Specimens were collected during April and May; those from Colombia at 1700 m; those from Venezuela with a black light set in a montane tropical cloud forest.

E t y m o l o g y: The specific epithet, agma, is a Greek noun with a meaning of "fragment". I refer to the fragmentation of the fascia on the elytral disc.

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