Description.

Female ( Fig. 14 ). Length, 7.0-9.0 mm Similar to male except metasoma more extensively white; mostly black on tergites 1 and 2, with decreasing amount of black toward apex.

Male.

( Fig. 15 ). Length, 4.0-9.5 mm. Antenna black, antennomeres 9-15 white and sometimes apex of 8. Head white with vertex black, with black extending to dorsal margins of eyes, partly down outer orbits, down outer margin of gena and broad stripe medially to antennal sockets ( Figs 17, 18 ). Clypeus with median broad black stripe ( Fig. 17 ). Mesosoma orange. Legs orange. Wings hyaline with veins and stigma black. Metasoma with tergites 1-3 orange to reddish brown, tergites 4 and 5 black and narrowly white at apices of tergites 5 - 7; tergites 2-5 with white lateral spots; sternites white except 4 and 5 with narrow black anterior margins. Male genitalia with gonostipes brown, paramere white.

Antenna with 26-28 antennomeres. Head from above almost straight behind, distance behind eyes about 0.8 × eye length, with scattered fine punctures ( Fig. 18 ). Mesoscutellum with anterior width slightly shorter than medial length. Metascutellum 2 × broader than long. Propodeum with coarse reticulate sculpture ( Fig. 16 ). Mesonotum shiny with small punctures separated by flat shiny interspaces mostly 2 × or more puncture diameters. Male genitalia with paramere about 1.5 × as long as broad, narrowing to acutely rounded apex ( Fig. 20 ), about 0.8 × length of gonostipes ( Fig. 19 ).

Host.

Benoit (1951) mentioned that a specimen was obtained by Seyrig from rearing of a limacodid moth.

Distribution.

Madagascar: Antananarivo (Ankaratra, Benoit 1951), Fianarantsoa, Mahajanga (Andreba, Benoit 1951), Toamasina, Toliara Tanzania ( Carmean and Kimsey 1998).

See discussion under Orthogonalys gigantea for characters separating the two species. This is the most commonly collected species in Madagascar and occurs from the lowlands to high altitude rainforests. We have examined about 130 specimens.
