Description: Exuvium . Body 1.9 cm long, light brown, not narrow or elongated; profile curved. Legs and ventral side sparsely covered with bristles ( Fig. 2 ). Fig. 2. Lateral view of exuvium of Pycna semiclara . Scale bar = 5 mm. Head. In dorsal view, including eyes, about twice as wide as long; slightly wider than anterior margin of pronotum. Antenna small, not extending past clypeus; with six segments. Clypeus in dorsal view rounded, bulbous; profile rounded. Rostrum reaching base of metacoxae. Thorax . Pronotum in dorsal view about half the length of mesonotum. Metanotum very small compared to pronotum and mesonotum. Apex of fore wing reaching third abdominal segment; hind wing reaching third abdominal segment ( Fig. 2 ). Legs and ventralregion of thorax with sparse setae. Profemur ( Fig. 3A ) with posterior tooth long, sharp, curved forward slightly; about 3× as long as wide at base. Accessory posterior tooth small, blunt. Intermediate tooth present. Diastema betweenintermediate tooth ( itf ) and posterior tooth ( ptf ) wide; diastema between itf and ptf longer than length of ptf . Profemoral comb with 7 teeth.Apical toothof comb slightly blade-like; pointed. Protibia ( Fig. 3A ) withwell-developed blade; untoothed; with one pointed, well-developed, preapical tooth. Apical tooth about 1.5× as long as width of base; separated from previous tooth by deep notch. Protarsus ( Fig. 3A ) two-segmented; apical tarsomere elongated; protarsal claws of unequal size. Mesotibia ( Fig. 3B ) without lateral spines or protrusions; with five apical spines, one much smaller than the others. Mesotarsus two-segmented; apical tarsomere elongated; mesotarsal claws of unequal size. Metatibia ( Fig. 3C ) with four large apical spines and two or three much smaller spines situated slightly higher up on leg and between the larger spines. Hind tarsus ( Fig. 3C ) two-segmented, apical tarsomere elongated; metatarsal claws of unequal size. Abdomen ( Fig. 2 ). Short, cylindrical in cross section; in dorsal view, lacking distinct waist; with few ventral setae. Abdominal tergites without transverse rows of setae; tergites 6–10 with sparse hairs; tergite 7 with dark spot either side of midline. Sternites three-quarters the width of abdomen proximal to thorax, tapering distally to onetenth the width of abdomen; covered with white tomentum. Sternite 1 lacking median protruberance. Sternite 10 of male with a single protrusion, pointed apically. Fig. 3.
