Parasynegia Warren

Type species: pluristriaria Warren, India.

This genus shares with Yashmakia a general similarity of facies, at least for some species, an enlarged retinaculum (massive, distinctly spatulate, with a slight blister formed on the wing membrane at the apical extremity of the retinaculum just beyond the posterior vein of the cell), and strong coremata at the valve bases. The antennae of both sexes are also similar.

The fasciation of the wings is fine, more angular and linear. The forewings are not angled in the centre of the margin, and the hindwings only slightly so in the same two positions as in Yashmakia. In the male genitalia the uncus is not expanded broadly at the base, only at the extreme base, and the concentration of setae is more distal. Weak socii are present. The valve lacks a setal peg but has prominent processes on the costa: a broad basal one; a digitate one centrally. The juxta is diagnostically ‘horned’. The aedeagus has an apical spur, and the vesica has only a small clump of needle-like spicules on the diverticulum and some scobination on the main tube. In the female genitalia (sundastriaria) the ductus is broad, short, sclerotised, asymmetric. The bursa is slender, long, the basal third lightly sclerotised, fluted, with a longitudinal zone of spines distally, the stellate ‘mushroom’ signum set centrally in concentric rings of corrugation of the membrane, and the distal half immaculate.

The limits of the genus need revision, but it should certainly include the Himalayan P. diffusaria Moore in addition to the type species and those discussed below.
