Ossuaria Dworakowska, 1979

Ossuaria Dworakowska, 1979: 18

Type species: Ossuaria agara Dworakowska

Forewing (Fig. 25) with small brownish patch adjacent to CuA”.

Body slim. Head narrower than pronotum. Vertex slightly produced medially, coronal suture distinct. Forewing (Fig. 25) with 1st and 3rd apical cell large and broad, 2nd apical cell narrow, slightly wider at apex than at base, 4th apical cell very small not reaching apex of forewing. Hind wing (Fig. 26) with submarginal vein absent at costal margin.

Abdominal apodemes (Figs 27, 28) quite slim and long, exceeding posterior margin of 4th sternite.

Male genitalia: Genital capsule cylindrical. Pygofer (Figs 1, 2, 10, 11) moderately sclerotized at upper margin, otherwise semitransparent; dorsal appendage narrow basally and broad apically; group of short macrosetae at cephalo-ventral angle, row of rigid microsetae at hind margin and several short feeble microsetae on depressed ventral part of lobe. Subgenital plate (Figs 4, 13) narrowing apically, directed upwards about 1/3 distance from tip in lateral view; several macrosetae form oblique row at about midlength of plate and some short stout setae on marginal plica from near base to subapex. Paramere (Figs 5, 6, 14) slender with very short central part and quite small praeapical lobe. Connective (Figs 7, 15) with long stem, small distinct central anterior lobe and two lateral lobes.

Aedeagal shaft (Figs 8, 9, 16–20) tubular with paired subapical processes, gonopore subapical on ventral surface; preatrium small, dorsal apodeme well developed.

Distribution. Vietnam; China (Yunnan, Sichuan).

Note. Ossuaria is similar to Ratburella Ramakrishnan et Menon, but can be distinguished from the latter by the vertex being slightly produced medially; the forewing with the 4th apical cell smaller and the apical cells shorter; the hind margin of the male pygofer with a row of microsetae; the subgenital plate with several macrosetae situated at about midlength; the stem of the connective much longer; and the paramere apex slender, without processes.
