Holotype

Male, labeled “Madagascar, Fianarantsoa, Parc National Ranomafana, Belle Vue at Talatakely, elev. 1020 m, 15–28 May 2003,” “21°15.99'S, 47°25.21'E, coll. M. Irwin, R. Harin’Hala, California Acad. of Sciences, Malaise, secondary tropical forest, MA-02-09C-61” (CAS).

Paratype

“Madagascar, Fianarantsoa, Miandritsara Forest, 40 km S Ambositra, 20°47.56'S, 47°10.54'E, 5–19 March 2005,” “California Acad. of Sciences, coll: M. Irwin, R. Harin’Hala, Malaise trap, in low altitude rainforest, elev. 825 m, MA-29-11” (1 ♂, CAS).

Description

Female. Unknown.

Male

(Fig. 29). Length, 10.0 -11.0 mm. Antenna black; antennomeres 11 at apex, 12–15, and base of 16 white. Head white with vertex and upper frons black, black extending to dorsal margins of eyes and medially to near antennal sockets (Figs 31, 32); clypeus white. Mesosoma orange with posterior lateral angles of pronotum white and metascutellum yellow; pleura and sterna lighter orange than dorsum. Legs orange with hind tibia and tarsus black. Wings hyaline with veins and stigma black. Metasoma with tergite 1 mostly black, tergites 2–4 orange, tergite 5 mostly black, and tergites 6 and 7 white, narrow lateral edges of tergites white and sternites mostly white; genitalia with gonostipes brown and paramere white.
Antenna with 28–29 antennomeres. Head from above slightly emarginated behind; head behind eyes about 0.8× eye length (Fig. 32). Anterior width of mesoscutellum about 1.2× medial length; shallow, median longitudinal groove on posterior half (Fig. 30). Metascutellum 2× broader than long. Mesonotum shiny with closely set punctures, mostly separated by shiny interspaces 1 – 2× puncture diameters. Propodeum with irregular transverse carinae at center, more reticulate on sides (Fig. 30). Paramere of male genitalia about 1.8× as long as broad, broadly rounded at apex (Fig. 33), subequal in length to gonostipes (as in Fig. 28).

Etymology

From the species name “hova” with the Greek prefix ”para” meaning resembling Orthogonalys hova.

Remarks

This species is similar to Orthogonalys hova, and initially we considered the two males as large specimens of that species. However, the following differences justify its recognition as a distinct species: antenna with only about 4 central antennomeres completely white; clypeus white; genae almost completely white; posterior angles of pronotum white; mesoscutellum with anterior width about longer than medial length and with distinct median furrow in posterior half (Fig. 30); and paramere of male genitalia longer, about 1.8 times as long as broad and rounded at its apex (Fig. 33). The parameres resemble the long, rounded parameres of Orthogonalys maculata.
