Description. FEMALE. See Lelej (2005). MALE. Head width less than pronotal width, not rounded posterad. Preoccipital carina dorsally well developed, sharp and slightly projecting behind head. Eyes well notched inside. Ocelli small, ratio POD:OOD=0.75. Mandible bidentate without basal tooth beneath and without subbasal tooth on inner border. F2 1.25 ×F1. Prementum with raised mesal longitudinal carina. Notauli well visible in posterior half, parapsids weak. Tegula longer than pronotal length laterad, projecting over axilla. Propodeal posterior slope with strong longitudinal medial carina which ends dorsally in tubercle. Metasomal segment 1 widely transverse. T2 with long lateral felt line, S2 without any lateral felt line. Sternum 8 (hypopygium) not modified. T7 obscurely angulate laterally, apical border smooth with wide medial smooth triangle marked by blunt carinae laterally. Gonostylus wide, basiventrally setose. Volsella slightly longer than penial valve and consists of wide cuspis and short fingerlike digitus; penial valves symmetrical, posterior margin with vertical row of setae, postero-ventrally bidentate, pre-apical tooth sharp, larger than apical tooth.

Head orange-brown with mandible, clypeus, and postgenal area blackened. Antennae black, except scape with obscure yellow-brown apical area, scape and pedicel with brown and whitish setae. Head densely punctured, setae interspersed pale yellow and dark brown. Mesosoma orange-brown, except mesopleuron ventral half, metapleuron, and propodeum black; setae predominantly silvery-white laterally, dorsal setae largely orange-brown. Tegula moderately punctate, laterally and posteriorly smooth. Pronotum, mesoscutum, mesoscutellum, and mesopleuron coarsely areolate-punctate; propleuron with large shallow punctures; metapleuron smooth; propodeum areolate. Legs with dense whitish setae. Metasoma blackish-brown with distinct purple lustre. T1–2 densely punctured, sparser on disk of T2. T1–3 and S2–5 with apical fringes of whitish setae; T4–6 with setae black, with few scattered erect whitish setae on discs laterally. Wings fusco-violaceous.

Remarks. The male of this species was recognized only after the sex association of Kurzenkotilla harmandi , comb. nov. (see below) was discovered. The newly recognized females of K. harmandi initially appeared to be conspecific with K. annamensis , but closer examination revealed that they represented different species, particularly due to the differences in the metasomal setal pattern and the constricted mesonotum of K. harmandi . The male here recognized as K. annamensis occurs in southern Vietnam, where the type and other examined female of K. annamensis have been examined, but K. harmandi have not been seen. Furthermore, this male has different metasomal setal markings (as discussed in the key above) than K. harmandi . Additionally, it has the mesoscutum clearly wider than long, while the male of K. harmandi has the mesoscutum only scarcely wider than long; likewise, females of K. annamensis have a wider mesonotum than that of K. harmandi .
