Hybridoneura Warren
Type species: abnormis Warren, N.E. Himalaya.
Synonyms: Pseudomimetis Prout (type species semiviridis Prout
after Warren (see species description for H. picta Warren)) syn.
n.
The male of abnormis has distinctive secondary sexual
characteristics, notably a translucent subdorsal zone on the forewing like a
pair of white lips divided by vein CuA1 and bounded by M3 and CuA2. The hindwing
is more or less triangular, narrowed costally, with Sc + Rs on the costal edge,
and M1 sigmoid. The cell is relatively deep. The male antennae are filiform.
The male genitalia are characterised by large and highly complex
corematous structures suspended on arms from the valve bases. A major component
of this is a striate leg-and-foot-like structure.
In the female the bursa is somewhat pyriform, with the ductus seminalis
arising asymmetrically from its base. There are two longitudinal bands of spines
amid more general spining within it.
Pseudomimetis lacks the extreme secondary sexual structures of the male forewing and
coremata, but is brought into synonymy on grounds of the following
synapomorphies with Hybridoneura: the straight, transverse medial of the
forewing; the bilobed or biangular basal margin of the male eighth sternite; the
ovate-elongate shape of the base of the juxta; the broadening of the tegumen;
the suspension of the coremata on arms; the rather black, granular ornamentation
of the aedeagus vesica; the female bursa.
A similar pair of arcuate bands is found in the bursa of Pasiphilodes
subtrita Walker but this lacks the other features mentioned
above.
In addition to the type species of the genus-group names, the genus is
represented in New Guinea by H. truncata Prout, a close relative of H.
abnormis.
