Diagnosis

Female

Head and mesosoma brown ( Figs 33–34 , 37–38 ). Flagellum yellowish, clava darkening towards apex ( Fig. 36 ). Macropterous ( Fig. 32 ); fore wing subhyaline ( Fig. 40 ). Clypeus wider than high; margin produced ( Fig. 35 ). Scrobes shallow and reticulate. Upper face and vertex with eight large setae. Occiput margin sharply defined ( Fig. 34 ). Eye height about 2.5× malar space. POL about 5.5× OOL. Antenna strongly clavate ( Fig. 36 ). Pronotal collar not unusually long or wide ( Fig. 38 ). Mesoscutum, scutellum and axillae with shallow reticulation ( Fig. 38 ); scutoscutellar sutures deep, distinct ( Fig. 38 ); frenal area distinct, i.e., sculpture at least slightly different than rest of scutellum ( Fig. 39 ). Setation of mesonotum not unusually dense and conspicuous ( Fig. 38 ). Mesepimeral sulcus conspicuous ( Fig. 37 ). Propodeum without a well-defined V-shaped area basally ( Fig. 39 ). Fore wing with basal third extensively setose except for narrow bare region ( Fig. 40 ); MV about 5.3× SV. Visible part of petiole very short, distinctly transverse, with more or less obliterate sculpture ( Fig. 39 ).

Etymology

The name of the species (noun in the genitive case) refers to the collecting place, Celebes, being an older name of Sulawesi.

Female (habitus: Fig. 32 )

COLOUR. Head ( Figs 33–35 ) brown. Mandibles light brown, teeth darker. Antenna ( Fig. 36 ) with scape whitish, pedicel pale yellow except brownish dorsally, funicle pale yellow and clava brown. Mesosoma ( Figs 37–39 ) reddish-brown, but sutures, metanotum, propodeum and mesepisternum darker. Legs with coxae light brown, fore and mid trochanters, trochantelli and femora light brown, hind trochanter, trochantellus and femur whitish, tibiae and tarsi whitish, pretarsi brown. Fore wing ( Fig. 40 ) slightly and uniformly infumate; venation light brown; setation brown. Hind wing hyaline. Metasoma with petiole dark brown ( Fig. 39 ); gaster mainly brown, ventrally paler. Body setation whitish except for several large, symmetrically arranged, dark brown setae.

BODY LENGTH. 2.3 mm.

HEAD. Clypeal almost smooth; apical margin slightly produced ( Fig. 35 ). Lower face with shallow piliferous punctures among reticulation. Upper face, including shallow scrobes and adjacent areas, reticulate, with reticulation becoming denser towards vertex. Occiput smooth; margin sharply defined ( Fig. 34 ). Toruli with lower margins slightly below lower margins of eyes ( Fig. 33 ). Antenna with flagellum strongly widening towards clava; clava conspicuously asymmetric ( Fig. 36 ). Upper face and vertex with eight large setae. Head in dorsal view with width about 2.2 × length (49:22) and in frontal view about 1.1× height (49:43). POL about 5.5× OOL (16.5:3.0). Eye height 1.4× length (28:20), about 2.5× malar space (28:11) and about 1.3 × scape length (28:22). Head width subequal to length of pedicel plus flagellum (49:47). Fu1 length about 1.2× width (3.5:3.0); fu7 width 1.75 × length (7:4); clava length about 2.2× width (19.0:8.5).

MESOSOMA. Pronotal collar narrower than mesoscutum, with six large setae ( Fig. 38 ). Mesonotum moderately setose dorsally ( Fig. 38 ). Mesoscutum and axillae with shallow reticulation ( Fig. 38 ). Scutellum on anterior part with shallow reticulation and longitudinally striate-reticulate on frenal area ( Figs 38–39 ). Mesepisternum densely reticulate. Mesepimeron mainly smooth, except for shallow striation dorsally; mesepimeral sulcus conspicuous ( Fig. 37 ). Propodeum with intricate pattern of carinae, interspaces large, smooth to slightly wrinkled ( Fig. 39 ). Macropterous; fore wing ( Fig. 40 ) uniformly and densely setose except for small, elongate bare region. Mesosoma length 1.25 × width (50:40) and about 1.4 × height (50:35). Pronotal collar about 0.3× as long as mesoscutum (4.5:14.0) and about 0.8 × as wide as mesoscutum (32:40). Mesoscutum width 2.85 × length (40:14). Scutellum length about 0.9× width (21:23). Propodeum length about 0.6× scutellum length (13:21). Fore wing length about 2.6 × width (103:40); MV about 5.3× SV (32:6) and about 2.1× PV (32:15).

METASOMA. Petiole ( Fig. 39 ) very short, transverse, with a few longitudinal costulae. Gaster ( Fig. 32 ) ovate, length about 1.9× width (75:39); gt1 longest, width 1.3× length (39:30), with hind margin slightly produced; gt2–6 short; syntergum acutely pointed. Ovipositor sheaths slightly protruding beyond apex of gaster. Cercal setae not surpassing apex of gaster.

Male

Unknown.

Distribution

Indonesia (Sulawesi).

Remarks

The only known female of this species most closely resembles females of N. ramakrishnai , from which it differs mainly in the colouration of the head and antenna, the wider than high clypeus and the longer POL.
