D i a g n o s i s: Within the M. testacea group, only in members of this species does the pronotum show 2 very broad black lines. Also, the elytra are bicolorous with black markings that show a bluish luster.

D e s c r i p t i o n: Size: Length 9.0 mm; width 3.8.0 mm. Form: As in Fig. 154 . Color: Mouthparts, except mandibles, antennae, cranial venter, prothoracic sternum, legs, pterothorax, and abdomen light castaneous, cranial dorsum black; pronotum with 2 broad black lines, otherwise castaneous; elytra mostly castaneous, with black markings as shown in Fig. 154 . Head: Funicular antennomeres subfiliform, capitular antennomeres 9 and 10 triangular ( Fig. 38 ), antennomere 11 ovate; frons wider than width of eye ( EW /FW 40/50). Thorax: Pronotum (Fig. 76) quadrate ( PW /PL 125/125), side margins with well-developed tubercles, disc coarsely punctate at sides, narrowly subglabrous at middle; elytral asetiferous punctation striate at middle of elytron, punctures end at elytral distal 4/5 th ( EL /EW 360/110). Abdomen: Pygidium scutiform; 6 th visible sternite only slightly concave at posterior margin; aedeagus, phallic apex as in Fig. 122.

V a r i a t i o n: Size: Length 8.5-9.0 mm; width 2.5-3.8 mm. The black markings on the elytral disc are more pronounced in one specimen.

N a t u r a l h i s t o r y: Specimens were collected during December and January, at altitudes that range from 1000 to 1350 m.

E t y m o l o g y: The trivial name, sigilla (= signum), is a Latin noun. I refer to the dark, shield-like, configuration of the castaneous portion of the elytral disc.

D i s t r i b u t i o n ( Fig. 97 ): This species is known from Bolivia.
