Description
Female (Fig. 21). Length, 14 mm. Similar to male except metasoma white laterally and ventrally and tergites 1–4 mostly black dorsally, 5 and 6 black anteriorly.
Male
(Fig. 22). Length, 8.5–12.0 mm. Antenna black with antennomere 10 white at apex, 11–12 completely white, and 13–15 partly brown on lower surface and white on upper surface (Fig. 26) or 11–14 completely white. Head white with vertex black, black extending to dorsal margin of eyes, down posterior margin of gena, and anteriorly onto frons to antennal sockets (Figs 24, 25). Mesosoma anterior to transscutal articulation red, posterior to transscutal articulation black with mesoscutellum and metascutellum white; pronotum with anterolateral margins white and laterally white with broad black intermediate stripe; mesopleuron and mesosternum mostly white with black on dorsal margin and margins of mesepimeron black; metapleuron mostly white. Legs orange with hind tibia and basal half of basitarsomere darker, hearly black. Wings hyaline; veins and stigma black. Metasoma mostly orange; tergite 1 mostly black, tergites 2–6 orange with black spots at apices of tergites 5 and 6 and sometimes laterally on tergites 2 and 4, and apical tergite white. Male genitalia with gonostipes brown and paramere white.
Antenna with 28–29 antennomeres. Head from above nearly straight behind; distance behind eyes about 0.7× eye length (Fig. 25). Mesoscutellum as long as broad, anterior width 0.8× medial length; metascutellum about 1.4× broader than long. Propodeum with coarse reticulation anteriorly, 4 or 5 irregular transverse carinae posteriorly (Fig. 23). Mesonotum shiny, with fine punctures mostly separated by shiny interspaces 3× or more than puncture diameters. Male genitalia with paramere about 1.5× as long as broad, broadly rounded apically (Fig. 27); subequal to length of gonostipes (Fig. 28).
Distribution
Madagascar: Antsiranana, Fianarantsoa, Toamasina.
Remarks
The color of Orthogonalys maculata is almost identical to Orthogonalys seyrigi, which probably led to its description only as a form of that species by Bischoff (1933)[4]. Color differences in Orthogonalys maculata include only 2–4 central antennomeres completely white, darker to black hind tibia and tarsus, and mostly black first metasomal tergite. Orthogonalys seyrigi has more antennomeres completely white, usually 6, orange hind tibiae and tarsi concolorus with the rest of the legs, and the first metasomal tergite orange. Other differences in Orthogonalys maculata are the narrower mesoscutellum, which is slightly as long as broad (Fig. 23), and the paramere of the male genitalia which is long and white (Fig. 27), much more like the parameres of Orthogonalys gigantea and Orthogonalys hova, rather than the short, brown paramere of Orthogonalys seyrigi (Fig. 39). Because of the similar male genitalia, we regard this species more closely related to Orthogonalys gigantea and Orthogonalys hova rather than to Orthogonalys seyrigi.
