Aeologramma
Strand
Type species: picatum
Butler.
Synonyms: Poecilogramma
Butler (praeocc; type species picatum); Pseuderiopus Warren (type
species albiscripta Hampson).
Species included in
this genus are small with distinctively patterned forewings. In the type species
and a new species this consists of pale, oblique bands, separated by darker
fasciae and three dark triangles along the costa. The pale pattern is much more
irregular, almost reticulate, in albiscripta Hampson, with a large, dark,
triangular mark on the dorusm. In all three species the forewing apex is
bisected by a broad, pale bar.
The genus is
somewhat better defined by features of the male abdomen. Basal hair pencils are
absent. The eighth sternite is apically bilobed or trilobed, and contains
subbasally a pair of small, globular coremata. The valves of the genitalia are
narrow, without a corona, with a harpe that extends almost to the apex, and is
fused to the valves almost completely in all except the type species. The type
species also lacks the clavus-like process subbasally on the sacculus of the
other two species. There is fusion between the valves of the sacculus bases. The
aedeagus vesica appears generally coarsely scobinate or spined in all three.
In the female
genitalia (albiscripta) the ostium is flanked by two angular processes at
the posterior margin of the seventh segment. The bursa is reminiscent of that of
some larentiine Geometridae in being finely spined throughout. It is
sclerotised over the basal third, where arise two acute processes, one almost
hornlike.
