Asphondylia Loew in Indonesia

Nine species of this genus are so far known from Indonesia. Two were initially well-described from Japan, but the types of four of the remaining species are in poor condition and those of the other three are lost. The taxonomy of this group depends equally on males, females, pupae and larvae, but three of the species here lack one or the other sex, two the pupa and six the larva. Nonetheless, the variety manifested by the few Asphondylia species known from Indonesia is intriguing, if only from what we can appreciate of the tarsal claws, whether thick or thin, some lobed, others anisomorphic within a species or sex. Interestingly, most of the known pupae share a triplet of lower frontal horns that form an equilateral triangle. We have refrained from making further comparisons among species because available specimens are not fully comparable.
