Diagnosis

Small species; face orange; general coloration yellow to orange with infuscate markings; antennae short (23 flagellomeres); face and clypeus smooth with sparse punctures; mesonotum granulate; area superomedia about 2 x longer than wide; female femoral tooth small; ovipositor long, apically sinuate; POL 0.5; OOL 0.8; CT 2.0; ML 0.8; OT 1.8–2.0; FFT 1.

Differential diagnosis

Species mainly characterized by the quite short antennae with 23 flagellomeres and the very weak microsculpture.

Etymology

Euphonic arrangement of letters.

Type material

Holotype

MADAGASCAR: ♀ ( CAS), Namoraka National Park , 16°28’ S, 45°20’ E, verbatim label data: “Madagascar, Mahajanga Province, Parc Nat Namoraka, November 2002 (colls Fisher, Griswold et al.), in tropical dry forest, California Academy of Sciences”, left median tibia, left hind tarsi and left antenna lacking.

Paratype

MADAGASCAR: 1♀ ( MNHN EY2493), same date and same locality. Ovipositor broken.

Description

Female

LENGTH. 3.1, 3.0 (2.8–3.1) (2 specimens).

HEAD. Frons, face and clypeus almost smooth with sparse punctures. Clypeus transverse and convex. Mandibular teeth subequal. Malar line moderately long. Ocellar triangle equilateral. Antenna short with 23 flagellomeres.

MESOSOMA. Slightly elongate, about 1.7 x longer than high. Pronotum sparsely punctate. Mesonotum as long as wide, granulate with sparse puncture along notaulus. Pleurae and propodeum densely punctategranulate. Area basalis triangular, petiolate or opposite, area superomedia about 2 x longer than wide. Legs: femoral tooth distinct but small.

METASOMA. Post-petiole and tergite 2 finely aciculate. Tergite 2 about 1.5 x longer than apically wide. Ovipositor long, apically distinctly sinuate.

COLOR. Holotype mainly orange. Yellow: upper part of orbits, gena, mandible, trochanters, tibiae and tarsi. Ocellar triangle and metanotum infuscate. Flagellum infuscate, orange at base, scape and pedicel orange. Wings hyaline, pterostima brown with an ivory white anterior margin. Tergites 1–3 brown, apically yellow, the following tergites yellow with a mid-longitudinal infuscate stripe. Paratype with coloration much lighter: base of antenna, legs and metasoma from tergite 4 entirely yellow.

Male

Unknown.

Distribution

Madagascar (Mahajanga province).
