Abricta complex of genera

Five genera are here considered to belong to the Abricta complex of genera, viz. Abricta Stål sensu str., Abroma Stål , Aleeta n.gen., Tryella n.gen., Chrysolasia n.gen. and Monomatapa Distant. These genera are characterized by the conjunctival claws at the distal end of the male theca, and a partially or strongly dilated fore wing costa. On the basis of their type species, Abricta and Abroma should probably be synonymized, a decision not formally adopted here as an assessment of the 18 species of Abroma lies beyond the scope of this revision.

Key to genera

1 Anterior margin of fore wing strongly dilated proximal of node, the maximum dilation greater than width of costal vein ( Fig. 55b) (Australian species) ........................................................................................................................ 2

Anterior margin of fore wing with dilation less than width of costal vein ( Fig. 41b) (non-Australian species) ....................................................................................... 3

2 Fore wing rarely less than 32 mm long, usually more than 40 mm; male genitalia with uncal lobes downturned at their distal ends ( Figs. 46, 47) (monotypic) ......................................................................................... Aleeta n.gen.

Fore wing never reaching 32 mm, usually less than 26 mm; uncal lobes upturned at their distal ends ( Figs. 100, 101) (14 species) ............................. Tryella n.gen.

3 Abdomen bearing distinct golden pubescence; male genitalia with conjunctival claws well developed and strongly recurved ( Figs. 35, 36) (monotypic, reputedly from Guatemala) ............................................. Chrysolasia n.gen.

Abdomen bearing silver-white or no pubescence; male genitalia with conjunctival claws small, gently curved in an arc ( Figs. 33,

34, 37–38, 42–45) .......................................................................................................................... 4

4 Male abdomen much broader than thorax; male genitalia with conjunctival claws laterally directed ( Figs. 33, 34) ..................................... Monomatapa Distant

Male abdomen as wide as thorax; male genitalia with conjunctival claws ventrally directed ( Figs. 37–38, 42–45) .............................................................................. 5

5 Male with upper pygofer lobes near triangular with apex sharply pointed in lateral view ( Figs. 37, 38, 42, 43) (2 species, Mauritius & Reunion) ................................................................................................... Abricta Stål sensu str .

Male with upper pygofer lobes small, tending linear, apically rounded in lateral view ( Figs. 44–45) (18+ species, Mauritius,

Madagascar, Sri Lanka, India, and doubtfully Asia, South America,

Philippines) .................................................................................................................. Abroma Stål
