Mimocagosima ochreipennis Breuning

( Figs. 12–16 )

Mimocagosima ochreipennis Breuning, 1968 , Bull. Soc. R. Sci. Nat. Laos, 16: 32 ( Laos).

Description. Male: length: 16.3–21.0 mm, humeral width: 5.2–6.5 mm. Female: length: 20.0–22.0 mm, humeral width: 7.0–8.0 mm. Body black, reddish on tarsal claws and elytra. Head densely clothed with reddish brown or yellowish pubescence, with a small black spot on center of frons, a large black area on occiput; genae black with some whitish pubescence behind eyes; antennae black, with gray pubescence on basal part of antennomeres 2–11. Prothorax densely clothed with reddish brown or yellowish pubescence, with a moderate black area on centre disc, grooved in middle and ì8 î-shaped, or a big black area similar to that of M. humeralis ; a moderate black spot at middle of each side, behind spot with gray pubescence. Scutellum black. Elytra red and densely clothed with reddish brown or yellowish pubescence, except on three maculae: one humeral, irregular; second near middle of disc at end of basal third, round; third on lateral side just behind basal third, irregular, larger than other two. Ventral surface with gray pubescence on prosternum, mesepimeron, central portions of meso- and metathoracic sterna and posterior borders of abdominal segments; legs black, basal 8 antennomeres with moderate long hairs beneath. Head not quite as broad as prothorax, widest at genae, barely concave between antennal insertions, fine and unevenly punctured. Lower eyelobes rounded-oblong, slightly lower to subequal (female) or slightly longer (male) than genae. Antennae moderately stout, about 2/3 (female) or 5/6 (male) as long as body; antennomere ratio: male: 20 5 24 22 14 12 12 11 11 10 10; female: 19 5 24 19 14 11 11 10 10 9 9. Prothorax much broader than long, frontal half wider than basal half, bluntly nodose in middle of each side, raised on median line posteriorly with a node before base, punctures on the black area big, irregular and uneven, with some irregular ridges. Scutellum linguaform, width more than twice the length. Elytra prominent at humerus, enlarged before apex, very broadly rounded apically, sparsely punctured. Legs stout, hind femur nearly reaching apex of third abdominal segment. Male genitalia ( Fig. 15 ): Tegmen length about 3.0 mm; lateral lobes slender, each about 0.7 mm long and 0.2 mm wide, with setae except basal 1/3, with two small lobes furnished with short and fine hairs at the ventral base; with very short roof; ringed part elbowed in the widest portion, converging; basal piece not bifurcated distally; median lobe with median struts slightly curved, a little longer than tegmen (7:6); former subequal to latter; dorsal plate shorter than ventral plate; ventral edge of median orifice rounded; median foramen extremely elongated; internal sac short, with three rods and two small pieces at base of rods, the longest rods about 2.2 mm. Ejaculatory duct single. Female genitalia ( Fig. 16 ): Setae of sternite 7–8 long, extending beyond apex. Spermatheca S-shaped, about 1.7 mm long for a 20 mm adult. Tignum short, shorter than 1/3 of abdomen. Tignum 2.6 mm for an adult with a 8.0 mm abdomen in ventral view.

Diagnosis. Differs from M. humeralis (Gressitt) comb. nov. in having antennae shorter, in having apex of elytra becoming wider.
