Nordeniella Lelej, 2005: 48 , 145, 149, 185, ♁, ♀; Lelej & Brothers 2008: 40; Brothers & Lelej 2017: 95, ♁, ♀; Williams et al. 2019: 22 , ♀; Pagliano et al. 2020: 177; Okayasu 2022: 57, ♀; Thaochan et al. 2022: 158, ♀.

Type species. Mutilla thermophila Turner, 1911 , by original designation.

Diagnosis. MALE. Head angulate behind the eyes. Mandible tridentate, without subbasal tooth beneath.Clypeus rather flattened, anterior border with two medial tubercles. Ocelli small, POD less than OOD. Scape distinctly bicarinate beneath, F1 equal or slightly longer its width and evidently shorter than F2. Pronotum angulate. Notauli and parapsids developed in posterior half. Tegula slightly projected over mesoscuto-scutellar suture. Parascutal carina weak. Scutellum simple. Mesopleuron without precoxal ridge. Propodeum not shortened. Metacoxa mesally carinate. Wing well developed or shortened (in type species), slightly infuscated, stigmatic cell approximately equal to distance between base of stigmatic cell and origin of RS on vein Sc. T2 with long lateral felt lines, S2 without any trace of felt lines. T7 and S8 punctured throughout. Volsella slightly longer than penial valves, ventrally with tuft of basal setae, which no longer than cuspis. FEMALE. The female of this genus is separated from the other Smicromyrmini by F1 subequal F2. The female is similar to that of Ephucilla , Promecilla , and Sinotilla by having the mandible slender and the pygidial plate convex and smooth, but differs by the mesosomal lateral margins subparallel or divergent posterad (convergent in Ephucilla and Promecilla ), the scutellar scale obliterated (present in Ephucilla and Sinotilla ), and the lateral margins of pygidial plate convergent anterad and not carinate throughout (subparallel and with weak carinae posteriorly in Ephucilla ).

Diversity and distribution. Nine species (one known from both sexes, one based on males only, and seven based on females only) are recognized from India, Sri Lanka, Thailand, and Indonesia ( Lelej 2005; Williams et al. 2019; Okayasu 2022). Remarks. There are no available keys to separate the species in this genus.
