Comostola turgescens  

See Comostola pyrrhogona Walker comb. n. and genitalic distinction in the notes following.

Taxonomic notes. C. turgescens is a species distinct from pyrrhogona, sympatric with it. The male genitalia are distinguished by the presence of a pincer-like structure on the sacculus that varies in shape and size but shows a general decrease in the latter from the Himalaya to Sulawesi. Probably several races are involved: the genitalia of three are illustrated. The extent and complexity of the sclerotisation of the female lamella antevaginalis shows a similar trend.

Geographical range. N.E. Himalaya, Sundaland, Sulawesi.

Habitat preference. The species is rarer than the previous one, recorded from forested localities at 150m and 1000m on G. Mulu, at 300m in Ulu Temburong in Brunei, and at 1500m on G. Kinabalu.
