DIAGNOSIS. Elampus turcmenicus is a remarkable desert species, closely related only to the Moroccan E. rufirostris Linsenmaier, 1999 for habitus, small dimensions, shape of metasomal lamella, structure of T3 and shape of apical truncation of T3. It was known only on the male holotype (not female, as erroneously given in the original description) and we here describe the female. E. turcmenicus is separated from the northern African species by head entirely metallic red (vs. face and occiput black in E. rufirostris ); tegulae and tibiae metallic (vs. yellowish); metanotal lamella apically arched (vs. subtruncate); T2 apical margin metallic (vs. broadly hyaline). The body sculpture is unequal within specimens: generally has shallow,

lacunose punctures of various diameter, more or less scattered, or lacunose depressions instead of punctures or foveae, with large, polished and shining interspaces.

Only the metanotal lamella is covered by large foveate and contiguous punctures.

DESCRIPTION OF FEMALE (previously unknown). Body length 3.0–4.0 mm.

Fore wing length 2.5–3.0 mm. OOL = 2.1 MOD; POL = 2.6 MOD; MS = 0.3 MOD;

relative length of P: F1: F2: F3 = 1: 1.3: 0.9: 0.8.

Head. Frons, vertex, and face between eye and scapal basin, with medium to large (up to 1 MOD), shallow punctures ( Fig. 4A ), broadly separate (1–3 PD) or fully polished with shallow depressions (lacunose sculpture) in some specimens.

Punctures on ocelli area a little smaller and closer. Scapal basin asetose, deep and irregularly rugulose ( Fig. 4A ). Genae, in lateral view, impunctate or at most irregularly rugulose; malar spaces, in dorsal view, noticeably convergent. Clypeus medially extended in nose-like protrusion, about 1 MOD long and 1 MOD broad.

Ocellar triangle isosceles, with large POL (2.7 MOD). Postocellar line indistinct.

Mesosoma. Pronotum medially with shallow, lacunose, widely separated (1–3

PD) punctures, with polished, shining interspaces; with small, shallow punctures aligned along anterior and posterior margins ( Fig. 4C ); laterally with deeper and larger punctures ( Fig. 4B ). Mesoscutum with small, shallow, lacunose punctures,

mostly clumped along notauli and anterior margin; notauli and parapsidal furrows complete, tegulae impunctate. Mesoscutellum antero-medially widely impunctate,

shining, postero-laterally with lacunose punctures. Metascutellum with foveatereticulate punctures and elongate lamella, apically subelliptical; in lateral view,

lamella longer than mesoscutellum ( Fig. 4B ). Mesopleuron with shallow, large,

foveate punctures ( Fig. 4B ).

Metasoma. T1 with small, even punctures, subequally spaced (1–3 PD apart),

laterally closer. T2 dorsally with alike punctuation ( Fig. 4D ), laterally and posterolaterally double, with lacunose punctures and minute punctures in interspaces ( Fig.

4E). T3 with irregular punctuation, lacunose and contiguous. T3 lateral margins almost straight, slightly sinuous before apical rim; apical notch snout-like, distinctly protruding from apical margin ( Fig. 4E ); snout-like truncation narrow, of semi-

elliptical shape, slightly curved at base ( Fig. 4F ).

Coloration. Body color variable, from uniformly metallic red to purplish or coppery-bronze. Mandibles brown, apically darker; one male and one female with whitish mandibles, brown at apex. Scape metallic red, pedicel and flagellum black.

Legs metallic red, tarsi brown to light brown. Tegulae metallic red. Wings hyaline.

mesosoma, lateral view; C – mesosoma, dorsal view; D – metasoma, dorsal view; E – metasoma, lateral view; F – metasoma, posterior view. Scale bar = 0.5 mm.

Vestiture. Long (1.5 MOD), whitish, sparse and erected setae on head and mesosoma; shorter (1.0 MOD) and erect on legs. T1 and T2 with short and almost appressed setae, on T3 longer (2.0 MOD) and erect, contrasting with short setae on

T1 and T2.

Male. Similar to female, with elongate flagellomeres: F1 to F11 l/w> 1.5 (vs.

subsquare in female). Clypeal median protrusion less visible. Variable in coloration,

with specimens entirely metallic red, bronze or greenish (as the holotype). Tarsi light brown.

DISTRIBUTION. * Russia (Astrakhan Province); Turkmenistan.
