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.
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.
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
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.
