Petersenidia Lelej, 1992

Petersenidia Lelej in Lelej & Yamane 1992: 628, Lelej 1996a: 6, 1996b: 93; 2005: 70, Brothers & Lelej 2017: 96, Williams et al. 2019: 39 ; Pagliano et al. 2020: 255.

Type species Smicromyrme fukudai Tsuneki, 1972 , Japan, by original designation .

Diagnosis. MALE. Mesopleuron beneath without precoxal tubercle. S2 laterally with trace of felt line (a few punctures in P. fukudai , lacking in P. hylonome ). T7 with median glabrous area. Volsella without paracuspis, at most with setose tubercle between cuspis and digitus. FEMALE. Propodeum narrower than or as broad as pronotum; scutellar scale distinct; T2 disc with two laterally disposed white to golden setal spots; T2 apex without pale setal band, rarely with sparse fringe or medially interrupted band; pygidium defined by lateral carinae and usually entirely smooth. The pygidium of Petersenidia is usually wider and defined by stronger lateral carinae than in Krombeinidia .

Remarks. Like Krombeinidia , this large genus is more reliably defined by male morphology than female. Cur- rently the genus Petersenidia includes 44 species ( Lelej 2005; Pagliano et al. 2020), which are widespread in the Oriental region and penetrate to the Eastern Palaearctic. Only type species is known in both sexes, while 22 are known in male and 21 in females. There are no reviews or revision of this large genus.
