description: Cephaloleia dilaticollis Baly
Diagnosis: This species can be distinguished from the other three treated in this paper by the following combination of characters: dorsum with medial setose ridge, prothorax with central area micropunctate, mesothorax with anterior margin carinate, and venter with surface of extension rugose-punctate.
Color when alive (Fig. 6) pale yellowish-brown, margins translucent, with dark markings as follows: posterior margin and small medial spot on prothorax; mesothorax with medial longitudinal stripe and basal margin; metathorax and abdominal tergite 1 with medial longitudinal stripe and anterior and posterior margins; abdominal tergites 2–4 with medial longitudinal stripe; tergites 6–7 similar to metathorax; tergites 8– 10 with medial longitudinal stripe. Venter pale yellowish. Color when dead pale yellow with dark markings. Medial longitudinal ridge from anterior to posterior margin. Total length 5.7–6.0 mm (n=2); width 3.6 mm.
Dorsum. Prothorax with central raised area, surface micropustulate, with two diagonal carinae from central raised area to anterior margin, anterior and lateral areas punctate. Mesothorax with anterior margin carinate from side to side, laterally with sharply curved carina which extends to anterior margin, punctate laterally. Metathorax with diagonal carina which extends to lateral margin, punctate laterally; abdominal tergites 1–6 wider than long, decreasing in width, punctate laterally; Tergites 7–9 with two diagonal carinae on each side which extend to lateral margins; spiracles just off central elevation, with margins darkened, orifice as in Fig. 25.
Venter. Surface of extensions rugose-punctate. Head (Fig. 26) surface punctate; labrum with surface alutaceous, without setae; clypeus with fringe of long apical setae, with four setae on apical ½, surface alutaceous; mandibles tridentate; maxillary palps with 2 palpomeres and 12 short, robust apical setae; maxilla robust, clavate, with fringe of long apical setae; labium densely setose. Antenna with antennomere 1 longer than 2, subcylindrical; 2 wider than 1, transverse; 3 obconical, slightly longer than 2, with short apical setae. Prothorax nearly as wide as long. Meso- and metathorax wider than long; abdominal sternites 1–7 wider than long, decreasing in width, with three sulci on apical ½, laterally with curved sulcus dividing the sternite into thirds; sternite 8 similar to preceding but without any sulci; sterna 9–10 fused, rounded at apex. Legs (Fig. 27) robust; femur rugose-striate, with scattered setae; tibiotarsus obconical with scattered long setae and strong apical claw.
