Diagnosis. Miscophus globiceps belongs to the M. mimeticus species group, characterized by: female clypeal anterior margin continuous, without indentations; male S 8 in most species with fused medial teeth, split only at the apex. From all related species, M. globiceps clearly differs by a conspicuously convex frons and small size ( 3.1–3.6 mm).

Description. Head ( Figs 34–35 View FIGURES 31–36 , 41–42 View FIGURES 37–42 ) distinctly transverse. Frons shagreened (shinier in male), conspicuously convex, median sulcus indistinct.

Mesosoma. Pronotal collar wide, slightly depressed posterolaterally. Mesonotum sparsely punctate, shiny. Mesopleuron with indistinct sparse punctures, shiny; episcrobal area nearly impunctate. Propodeal enclosure with median keel and oblique rugae, without shiny interspases. Propodeal lateral surface obliquely striate. Setation sparse, not concealing sculpture.

Metasoma. Sparsely micropunctate, shiny.

Coloration. Black with following yellowish or straw-colored areas: clypeus anteriorly, mandible (except amber apex), scape and pedicel (darkened dorsally), pronotal lobe, tegula, femoral apex, tibiae, tarsi and S 6 in females. Mid- and hindtibial spurs dark brown. Apical parts of metasomal segments discoloured.

Female ( Figs 31–36 View FIGURES 31–36 ). Body length 3.2–3.6 mm ( holotype 3.6 mm).

Head ( Figs 34–35 View FIGURES 31–36 ) ratio H:W = 0.85, ratio POL:OOL = 1.78. Ratio head height to maximal frons width = 1.42. Clypeal anterior margin continuous.

Legs. Forebasitarsus with three spines, apical spine shorter than second tarsal article ( Fig. 33 View FIGURES 31–36 ).

Male ( Figs 37–42 View FIGURES 37–42 ). Body length 3.1–3.2 mm.

Head ( Figs 41–42 View FIGURES 37–42 ) ratio H:W = 0.55, ratio POL:OOL = 2.07. Ratio head height to maximal frons width = 0.97.

Legs. Forebasitarsus with two small spines.

Metasoma. S 8— Fig. 38 View FIGURES 37–42 .

Genitalia. Paramera— Fig. 39 View FIGURES 37–42 ; penial valvula— Fig. 40 View FIGURES 37–42 .

Etymology. The species name derives from two Latin words: “globulus”—sphere and the suffix “ceps”, from “caput” and “cephalus”, meaning head, characterizing the shape of the head.

Distribution. Russia ( Astrakhan Province).
