Holotype: female, MADAGASCAR, Mahajanga Province, Parc National de Baie de Bali, elev. 10 m, 16° 00’ 36” S 45° 15’ 54” E, 26-30 Nov. 2002, coll. Fisher, Griswold et al. CAS ( CASENT No. 2066001).

Paratypes. 15 females, same data as holotype: 10 females ( CAS, CASENT numbers 2066000, 2066002–9, 2066299); two females ( ZISP, CASENT numbers 2019490–91); two females (CNIN-UNAM, CASENT numbers 2020384 and 2066700); one female ( BNHM, CASENT number 2020379; specimen sequenced).

Description. Female (n = 16). Body length 1.8–1.9 mm. Head (dorsal view) 1.3–1.4x wider than medial length, 1.6–1.7x wider than mesosoma at tegulae; distinctly roundly narrowed behind eyes. Antenna approximately 0.8x as long as body length. Scapus 1.8x longer than wide. First flagellar segment 3.0–3.2x longer than apical width, 1.2–1.3x longer than second segment. Penultimate flagellar segment 1.7–1.8x longer than wide, 0.5–0.6x as long as first segment, 0.8–0.9x as long as last segment. Last flagellar segment without apical spine. Transverse diameter of eye 1.0–1.2x longer than temple length (dorsal view). Antennal socket 1.0– 1.1x longer than distance between sockets, 1.1–1.2x longer than distance between socket and eye. Eye 1.2– 1.3x higher than transverse diameter. Malar space 0.8–0.9x eye height, 1.8–2.0x higher than basal width of mandible. Face 1.3–1.4x wider than eye height and 1.2–1.3x wider than face and clypeal height combined. Hypoclypeal depression 0.6–0.7x as wide as distance from nearest part of depression to eye, approximately 0.4x as wide as face width. Hypostomal flange distinct. Mandible 1.2x longer than broad. Head below eyes distinctly convex and roundly narrowed (frontal view).

Mesosoma. 1.4–1.5x longer than high, 1.6–1.7x longer than wide. Mesonotum 2.6–3.0x longer than pronotum, 1.8x longer than propodeum (dorsal view). Mesoscutum 1.4x wider than medial length. Prescutellar depression bearing 5 carinae, with finely granulose sculpture between each carina, about half as long as scutellum.

Legs. Hind femur 4.0–4.3x longer than wide. Hind tarsus 0.8–0.9x as long as hind tibia. Hind tibia slen- der, slightly widened posteriorly. Second segment of hind tarsus 0.4x as long as hind basitarsus, 1.2–1.3x longer than fifth hind tarsal segment (excluding pretarsus).

Metasoma. 2.1–2.2x longer than maximum width, 1.2–1.3x longer than head and mesosomal length combined. First tergum strongly widened basally, then distinctly and almost linearly widened toward subapex and weakly widened apically, 0.6x as long as its apical width, 1.3–1.5x longer than propodeum. Apical width of first tergum 1.7x width at dorsope, 2.7x width at base. Median length of second tergum about 1.1x basal width, 1.8–2.0x first tergum length, 1.2–1.3x third tergum length. Combined length of second and third terga 1.8–2.0x basal width of second tergum, 1.6x their maximum width. Ovipositor sheath 0.3–0.4x as long as metasoma, 0.6–0.7x as long as mesosoma, 1.2–1.5x longer than first tergum.

Sculpture and pubescence. Head smooth, dorsal part of face finely striate. Lateral portion of pronotum coarsely rugose-striate with dense granulation. Median lobe of mesoscutum at least finely rugulose-granulate, lateral lobes finely granulate anteriorly and almost entirely smooth posteriorly. Scutellum smooth. Mesopleuron mostly smooth, partially rugulose, rugose anteriorly. Propodeum densely and sometimes very finely granulate and at least partially rugulose; areola large, wide, pentagonal. Hind coxa smooth, finely punctulategranulate dorsally. Hind femur mostly smooth with fine reticulation laterally. First tergum with coarse and sparse longitudinal striae, virtually smooth medially between dorsal carinae, slightly rugulose. Second and third terga mostly smooth, second tergum finely striate on narrow lateral areas. Vertex with sparse, very short and recumbent microsetae. Hind tibia dorsally with dense, short and semi-erect setae, their length about 0.5x as long as maximum width of hind tibia.

Color. Head red-brown or light red-brown, malar space yellow. Mesosoma yellow. First tergum yellow; second and third terga brownish yellow or yellow, dark brown on narrow basal parts of both terga. Antenna
