Description: Female. 2.7 mm. Color: Brownish orange, with the following areas a lighter brownish yellow: clava, coxae, hind tibia and tarsi, dorsal region of GT7, and the following exceptions: F5 light brown becoming darker through F7, thick longitudinal light brown band on anterior half of GT1, meeting thinner transverse light brown band in middle of GT1; posterior third of dorsal surface and entire ventral surface of GT1 brown, becoming light brown on GT2–5; tips of ovipositor sheaths brown. Head: Subtriangular-circular in frontal view, slightly wider than high (1.2:1); head with short, white, sparse setae of uniform length; occipital carina present only as dorsal line; vertex lacunose becoming coriaceous on upper face to irregularly striate on lower face; ratio of ocellocular: postocellar: mid-to-lateral ocellus distance: lateral ocellus diameter about 2: 4.6: 2.8: 1; scrobe high, reaching 4/5 of distance from torulus to midocellus; scrobal basin polished; scrobal walls coriaceous; interantennal carina weak, reaching about 0.3X height of scrobe; toruli separated by 1.4 torulus diameters; antennae weakly clavate; scape height subequal to eye height; anellus about 3X broader than long; ratio of scape: pedicel: anellus: F1: F2: F3 about 23: 12: 1: 7: 7: 6; F4 slightly longer than broad; F5 as long as broad; clypeus poorly delimited. Mesosoma: Dorsally coriaceous-imbricate, becoming imbricate on scutellum; ratio of pronotum: scutum: scutellum: propodeum about 1.3: 2: 1.7: 1; mesosoma covered in fine, white setae; row of slightly longer setae on latero-posterior margins of pronotum; pronotum about 1.7X wider than long, sparsely and irregularly striate laterally; antero-lateral margins of pronotum with faint carina reaching 0.3X height of pronotum (may be mistaken for vertical striae); scutum wider than long (1.7:1); ratio of scutellum: frenum about 4.3:1; marginal rim of scutellum with lightly grooved, pitted lamella; metanotum medially with grooved, pitted lamella; propodeum mostly smooth, posteriorly lightly wrinkled; nucha irregularly transversely striate; plicae strong, pointing laterally; postspiracular sulcus with sparse, white setae, forming a dense row along posterior and medial (plical) margins, setae arching toward callus; setae on inner margin of callus arching toward plicae, forming a cylindrical tunnel around sulcus; postspiracular sulcus deep, mostly smooth, slightly rough posteriorly; spiracle 1.6X own diameter from metanotum; callus densely setose, projecting posteriorly beyond postspiracular sulcus; prepectus triangular, not in same plane as pronotum, abutting at about 100º angle; mesepimeron smooth, with divoted region near dorsal margin between fore and metawing insertions; femoral depression deep, smooth,well defined anteriorly; metapleuron smooth; all coxae with clumps of white setae on anterior margins; meso- and metatibias spinose; longer metatibial spur about 2.1X length of shorter, about 2.7X width of metatibia at point of spur insertion; metabasitarsus about 6X as long as wide, about 0.7X length of remaining tarsi; hind coxae faintly transversely striate; wings brachypterous, forewing about 0.3X length of metasoma; hind wings small, round, membranous, about 0.35X length of forewing; forewing without strong, dark setae; ratio of submarginal vein: marginal vein 3.3:1. Metasoma: About 1.8X length of mesosoma; ratio of GT1: GT2–6:GT7:ovipostor sheaths about 6.9:2.8:1.8:1; GT1 dorsally with sparse, white setae; GT4–6 each with single transverse row of white setae, sparse medially and denser laterally; ovipositor apico-dorsally serrate. Male: Unknown.

Netomocera Bou č ek

Netomocera Bouček 1954: 49–50 . Type species: Netomocera setifera Bouček (orig. desig. and by monotypy).

Diagnosis: Netomocera females are easily identified as they are the only diparines with a strongly asymmetrical clava. The female of Netomocera is most likely to be confused with Chimaerolelaps . Netomocera has a very short petiole (broader than long) and 2 pairs of scutellar bristles, while Chimaerolelaps has a long petiole (at least 2X as long as broad) and 4 pairs of scutellar bristles. The male of Netomocera can be identified by a combination of features. First, it has bristles on the vertex and dorsal surface of the mesosoma, similar to males of Dipara and Lelaps . The male of Netomocera can be distinguished from Dipara by having a short petiole (at most as long as wide), whereas Dipara has a long petiole (>2X longer than wide). Additionally, the male of Lelaps has a median clypeal tooth while the male of Netomocera does not.

Discussion: Netomocera is resolved in different positions in different analyses, usually as sister-group to either Lelaps or Dipara , although there is little evidence in the phylogenetic analysis to support this. The Lelaps clade has an F1 at least 1.5X as long as F2, and this character is variable in Netomocera (although Netomocera usually has an F1 subequal in length to F2, undescribed species have been observed with an elongate F1). Therefore, this feature is synapomorphic for the group in 1 of 2 most parsimonious reconstructions.

Number of Species: 7 described species.

Distribution: Cosmopolitan. Known from all continents except Antarctica.

Hosts: Unknown.

Key to species: Sureshan and Narendran (1990) provided a key to the Oriental and African species.
