Genus Neorthostigma Belokobylskij, 1998

Neorthostigma Belokobylskij 1998: 9; Fischer 2001: 65; Wharton 2002: 91 (as subgenus); Belokobylskij and Tobias 2007: 10 (as valid genus); Yu et al. 2016; Belokobylskij et al. 2019: 215.

Type species.

Neorthostigma eoum Belokobylskij, 1998 (= Aspilota macrops Stelfox & Graham, 1951).

Diagnosis.

Mandibles small, tridentate, with distinct complete transverse and curved submedian carina. Upper tooth very small; median tooth narrow and rather short; lower tooth more or less wide, lobe-shaped, rounded or with distinct angle ventro-distally, with several long outstanding curved setae. Paraclypeal fovea oval, long, almost reaching inner margin of eyes. Oblique sulci between margins of antennal socket and eye always absent. Antenna thickened; first flagellar segment distinctly longer than second segment. Mesoscutum without medio-posterior pit; notauli present only on anterior (vertical) part of mesoscutum; precoxal sulcus present, oblique and sculptured; propodeum variable, with distinctly delineated large areola and with different types of sculpture and longitudinal or transverse carinae. Fore wing: marginal cell not shortened; vein 2-SR always present and rather distinctly sclerotized; veins m-cu and cu-a strongly postfurcal; first subdiscal cell closed postero-apically by vein CU1b; vein CU1a arising from vein 3-CU1 before its middle. Metasoma more or less distinctly compressed laterally. Ovipositor sheath much shorter than metasoma.

Hosts.

Unknown.

Remarks.

Wharton (2002) treated this genus only as a subgenus of Orthostigma on the basis of similarity of mandibular characteristics. However, re-evaluation of the morphological diagnostic features widely applied for separation and diagnosis of genera within the Alysiinae (see also: Zhu et al. 2017), provides additional evidence of the distinction between Neorthostigma and closed genera (see above).
