FAMILY LASIOCAMPIDAE

Alompra Moore

Type species: ferruginea Moore.

This genus was revised by Tams (1953). It consists of two species that range from the Himalaya to Sundaland, though without complete coincidence.

The hindwing venation resembles that of preceding genera in having a pair of humeral veins (cf. Fig. 3), but the forewing venation is atypical in that veins R4 and R5 have a common stalk, with M1 arising more basally; this forewing configuration (Fig. 2) is more typical of the Neotropical family Mimallonidae (see key in Part 1 of this series), and is shared with Kosala and Chonopla.

Figure 2. Forewing venation of Lasiocampidae: top, typical configuration (Paralebeda); centre genus Bhima, bottom, 'mimallonoid' venation shown by Alompra. Radial veins 2 to 5 are indicated by numbers.

Figure 3. Hindwing venation of Lasiocampidae: left, most frequent South-east Asian configuration (paralebeda); top right, gastropachine configuration (Gastropacha leopoldi), with numerous humeral veins anterior to Sc, and a major additional cell between Sc and Rs; bottom right, Syrastrena, with rather basal humeral veins, otherwise similar to Paralebeda.

The forewings are triangular, a dark reddish brown, marked with brighter red in a circular subbasal patch crossed by a row of three or four dots and based on the dorsum; bright red areas may also occur at the cell end and in a submarginal band (roepkei).

Both male and female antennae are bipectinate, more strongly so over the basal half.

The male genitalia have the cubile deeply pouched, more elongate than in Kosala and the previous genus. The eighth sternite is modified as in Kosala.
