Cephaloleia dorsalis Baly

Diagnosis: This species can be distinguished from the other three treated in this paper by the following combination of characters: dorsum without medial setose ridge, prothorax with central area micropunctate, mesothorax without carinae, and venter with surface of expansions rugose-striate.

Color when alive ( Fig. 10 ) pale yellow, margins translucent, venter pale yellow. Color when dead dirtybrown with paler margins. Total length 6.4–6.7 mm (n=3); width 4.3–4.4 mm.

Dorsum. Prothorax surface of central elevation micropustulate, with two diagonal carinae laterally extending to lateral margin, carinae wide at base, narrowing apically to sharp point, surface laterally punctate. Meso- and metathorax with base elevated, slanting back to apex, narrowing laterally into sharp point, punctate laterally; abdominal tergites 1–6 wider than long, decreasing in width, base elevated, sloping back to apex, ending in sharp point, punctate laterally; tergites 7–9 with two diagonal carinae on each side, which extend to lateral margin; spiracles just off central elevation, with margins darkened; orifice as in Fig. 28 .

Venter. Surface of expansions punctate, rugose-striate. Head ( Fig. 29 ) surface rugose-punctate; labrum with surface alutaceous, without setae; clypeus with fringe of long setae at apex, with four setae on apical ½, surface alutaceous; mandibles tridentate; maxillary palps with 2 palpomeres and short, robust apical setae; maxilla robust, clavate, with fringe of long apical setae; labium densely setose. Antenna with antennomere 1 short, robust; 2 narrower than 1, transverse; 3 elongate, cylindrical, narrower than 2, with fringe of short apical setae. Pro- and mesothorax wider than long, slightly depressed in middle, surface rugose-striate. Metathorax longer than others, depressed in middle, with suture along apical margin; abdominal sternites 1–8 wider than long, decreasing in width, laterally with curved sulcus dividing the sternite into thirds; sterna 9–10 fused, rounded apical setae. Legs: femur short, robust; tibiotarsus subconical, with a strong claw and eight apical setae ( Fig. 30 ).
