. Type species:
Atkinsonia clerodendronella
Stainton, 1859
, by monotypy.
Generic characters.
Adult with red coloration of wings and thorax, body often with metallic luster. Head (
Fig. 1
) smoothly scaled, vertex broadly rounded. Labial palpus (
Figs 2
,
5
) ascending, third segment longer than second. Antenna (
Fig. 3
) stout, with rough scales; flagellum with dense pectinate scaling on dorsal edge, with long cilia in male anteriorly (
Figs 7–14
). Forewing (
Fig. 4
) lanceolate, apex produced triangularly; R4 and R5 stalked for basal 3/5, R5 reaching costa before apex, M3 arising from lower angle of cell, CuA1 and CuA2 from before lower angle of cell, 1A+2A furcate basally. Hindwing narrow, basally with a longitudinal hyaline space along dorsum or beneath cell (
Figs 6, 6
a); cell opening between M1 and M2; M2, M3, CuA1 and CuA2 sub-parallel; cilia about twice length of wing width. Hind tibia with mid and apical spurs bearing long setae, with whorls of long bristles at origin of spurs, tarsus with whorls of bristles at apex of two basal tarsomeres.
Male genitalia.
Uncus deeply concave or shallowly notched at middle, forming two posterolateral processes; with densely spaced long hairs laterally. Gnathos reduced or absent. Transtilla not joined medially, elongately barshaped or narrowly triangular. Sacculus narrow, reaching or not reaching ventro-apex of valva. Aedeagus without cornutus.
Female genitalia.
Antrum heavily sclerotized anteriorly. Ductus bursae usually shorter than corpus bursae. Corpus bursae rounded or elongate oval, with two signa. Ductus seminalis arising from ductus bursae at its border with corpus bursae or from a short distance posterior to corpus bursae.
Diagnosis.
The moths of this genus are surperficially similar to those of
Oedematopoda
Zeller, 1852
by having red forewings and the flagellum of the antennae with dense pectinate scaling on the dorsal edge.
Atkinsonia
can be distinguished in the male genitalia by the reduced or absent gnathos, and in the female genitalia by the ductus seminalis without spines at base. In
Oedematopoda
, the gnathos is developed, and the ductus seminalis has spines at its base.
