Sympis Guenée

Type species: rufibasis Guenée.

All species have a similar facies of a brown forewing with a distinctly more rufous section basal to a straight antemedial that may be narrowly defined by pale mauve. The narrow reniform is immediately distal to this when evident, and there is often a further rufous patch distal to the reniform. The hindwings are a dark brown without any rufous tinge and have a diffuse bluish white fascia represented centrally in the medial zone. The underside is dull brown and has more extensive mauve suffusion, particularly on the hindwing, which has a few zig-zag fasciae in the distal part. The male antennae are ciliate, with a distinctive tuft of long scales at the rather nodular base of the scape; the legs and labial palps are also somewhat tufted with mauve-grey scales, the foretibia with a pencil of cream-coloured hairs. The labial palps of the female are more elongate, with the second and third segments slender and straight.

In the male abdomen, the eighth sternite is triangular, produced beyond the tergite which is only slightly tapered; there are no lacunae, coremata or apodemes. The uncus and scaphium are similar to that of the Scoliopterygini, though the apex of the former is of the ball-and-claw type. The valves are highly corematous and densely scaled distally and externally at the base, with a series of processes from the costa to the sacculus more basally. There is no obvious saccus, but the vinculum is ventrally deeper with an unusual deep central cleft dorsally and a shallower one ventrally. The juxta is somewhat ovate, though with a pair of longitudinal ridges or thickenings ventrally that could possibly be derived from an inverted ‘V’. The aedeagus is slender, straight, the vesica globular, with a group of up to eight small spines.

The female genitalia have the ostium within the seventh segment, covered by development of the reduced sternite into a pair of tongue-like antevaginal plates. The ductus has a short sclerotised section at the base, then a more expanded, corrugated and slightly scobinate chamber from a basal angle of which the ductus seminalis arises. The small, ovate corpus bursae is distal to this chamber, separated by a slight constriction.

Apart from the type species, the genus includes
S. parkeri Lucas from Queensland and an undescribed species from New Guinea (females; slide 18709) with a more closely defined white band and more intensely whitened fringes on the hindwing and a more irregular white line on the forewing.

The biology of the type species is described below.
