Diagnosis.

Females of S. punctata are unique amongst all members of the genus by showing the following combination of characters. Body size large (30-39 mm), black, except T2 to the following tergites and sternites with reddish-brown maculae. Hairy, vestiture black, except scrobes and frontal spatium with white setae and apical fringes and maculae on second to last tergites and sternites reddish-golden. Wings dark brown, with violet reflection. Clypeus impunctate in the middle, longitudinally striated anteromedially; frontal spatium raised and impunctate in the middle, at sides contiguously punctate; frons impunctate, except for some close punctures laterad of anterior ocellus; frontal fissura extending up to anterior ocellus, the latter in a shallow pit; vertex sparsely punctate. Mesoscutum with punctures usually separated by 0.5 to 1 puncture diameter wide, a V-shaped impunctate area present posteromedially; scutellum sparsely punctate; metanotum and median part of propodeum largely smooth.

Male. Body length 26 mm. Black, the following reddish-yellow: paired lateral spots on T1 and T2, T3 almost entirely except black along its anterior and posterior margins. Vestiture white, except on fourth and the following abdominal segments, black. Wings dark brown, fore-wing darker anteriorly, with golden reflection.

Distribution.

China (Guangdong, Hainan); India, Indonesia, Malaysia, Myanmar and Vietnam.

Biology.

Lepidiota stigma (Fabricius, 1798) ( Coleoptera : Scarabaeidae : Melolonthinae ) was listed as its host by Thompson (1958). Leucopholis rorida (Fabricius, 1801) is also a host record, based on the label information mentioned above.

Remarks.

The female specimen collected from China (Hainan) was once designated as a subspecies of Lepidiota rubromaculata by Betrem (1928) without offering obvious differences. Gupta and Jonathan (1989, 2003) therefore ignored Lepidiota hainanensis as a subspecies. Luckily, we had the chance to examine the above specimens from Hainan (Fig. 3C, D ) and Sumatra (Fig. 3B ) in RMNH. Minor differences were noted: lateral spots relatively smaller (sometimes effaced on T2 and indistinct on T3 (Fig. 3D )) and more yellowish on T2 and T3 in female specimen from Hainan, while it is larger and more reddish on T2 and T3 in the specimen from Sumatra ( Lepidiota rubromaculata ). We also observed the male paratype specimen of the subspecies S. r. celebensis Betrem in RMNH. The reddish-yellow maculae are nearly effaced on T1 and T2 in Campsomeris celebensis , which is distinctly different from the nominate subspecies (Fig. 3F ).
