View Image Gallery of Tribe Rhodostrophiini

This group is characterised in the adult by a well developed, elongate or spatulate, often densely setose uncus in the male genitalia. The gnathus is well developed, apically acute. Part of the second sternite between the male tympanic bullae is setose or rugose, and the hind-tibia bears a hair pencil. The male antennae of most genera are robustly ciliate rather than bipectinate.

Female genitalia in the tribe are variable, but usually have the bursa generally scobinate, sometimes with a signum formed of a denser, more sclerotised area of scobination.

No diagnostic features for the larvae, apart from very slender build, have been located in the literature. Prout (1913, Gross-Schmett. Erde 4: 36) described the cremaster of the type genus as having two strong spines at the extremity, small knots at their base, and two pairs of hooks anterior to them. Nakamura (1994) noted a similar condition in Dithecodes Warren and Organopoda Hampson: a strong, bifurcate terminal pair, with two pairs of smaller hooks on a triangular cremaster. The F-seta of the head is bristly in these genera.

No strong host-plant specialisms have been noted, but most records are of arboreal feeding, though Prout (loc. cit.) referred to 'low plants'.

The type genus, Rhodostrophia Hübner, is primarily Palaearctic but extends into the Himalayan ranges and those of western China. Several of the genera discussed here were described by Prout (1932a).
