Diagnosis

Recognized by the following characters: elongate appearance; apical margin of clypeus narrower than interantennal distance and subtruncate, lateral teeth with thick carinae forming U-shaped ridge ( Fig. 3B ); vertex short, 1.4 × as long as distance between posterior ocellus and inner eye margin ( Fig. 3C ); pronotal carina sharp, shortly lamellate on humeri; T1 about as long as wide; apical translucent margin of T2 very short and barely noticeable, not separated from rest of tergite ( Fig. 3D ); head and mesosoma coarsely punctured, interspaces reduced to ridges, T1 and base of T2 with deep punctures.

Etymology

The specific epithet derives from the Latin adjective ‘anomalus, -a, -um’ (= ‘anomalous’), in reference to the differences from all other species of the genus.

Description

Female

MEASUREMENTS. Body length 9.7 mm; fore wing length 8.5 mm.

MORPHOLOGY. Head evenly rounded, 1.15 × as wide as long in frontal view. Clypeus 1.3 × as wide as long, apical margin subtruncate and narrow, 0.15 × as wide as maximum width of clypeus; apical teeth barely projecting and with short thick carinae, connected with the thickened apical margin and forming an U-shaped ridge, area between carinae shallowly depressed; clypeus in profile strongly and evenly convex from base to apex, smoothly passing into interantennal space. Vertex 1.4 × as long as distance between posterior ocellus and inner eye margin; cephalic foveae close to each other and equidistant from posterior ocelli and occipital carina, placed in a small shiny depression with raised V-shaped posterior margin; gena 1.25 × as wide as eye at bottom of ocular sinus; occipital carina fine on vertex, strong and lamellate on gena, delimiting a crenate furrow, strongly curved in lower half. F1 1.3 × as long as wide and 1.3 × as long as F2, F2–3 and F9 subquadrate, F4–8 transverse and becoming progressively shorter. Fifth tooth of mandible barely protruding and completely rounded. Mesosoma 1.4 × as long as wide. Sides of pronotum sinuate in dorsal view, slightly concave behind humeri, anterior margin straight; pronotal carina complete and sharp, shortly lamellate on lateral thirds and becoming higher on humeri; pretegular carina complete but dull, preceded by a shallow furrow. Mesoscutum 1.05 × as long as wide, weakly and evenly convex in lateral view; short hints of notauli on posterior margin. Scutellum flattened in lateral view, on same level of mesoscutum and smoothly passing into metanotum; anterior margin very shallowly crenate, pits more evident on extreme sides. Metanotum weakly convex, anterior margin with deep pits at extreme sides. Tegula short and not equaling parategula, outer margin straight in anterior third and rounded in posterior two thirds, slightly reflexed; parategula small, more or less right-angled. Mesepisternum elongate, more or less flattened dorsally, becoming convex ventrally; epicnemial carina low and rounded, reaching epipleural suture above. Propodeum evenly and weakly convex in lateral view; posterior face very shallowly concave, nearly flattened and smoothly passing into dorsal faces; lateral faces flattened; dorsal, lateral and inferior carinae absent, propodeum entirely rounded. T1 semi-elliptical, 0.7 × as long as wide in dorsal view; apical margin with a short hyaline lamella. T2 0.9 × as long as wide in dorsal view, apical margin 1.3 × as wide as basal margin, apically with a very short and barely visible translucent margin. S1 subtriangular, posterior margin concave and strongly raised. S2 almost straight in lateral view, then strongly sloping basally; basal margin with shallow subtriangular depression and a barely visible short longitudinal furrow; apically with short lamellar margin, longer than that on T2.

SCULPTURE AND VESTITURE. Clypeus on disc and apical part shiny with sparse micropunctures and irregular macropunctures, punctures variable in depth and interspaces ranging from half to two puncture diameters, some punctures touching; basal third and lateral thirds densely micropunctate near disc and shagreened near margins, finely and sparsely punctured. Frons and vertex coarsely and deeply punctured, punctures very dense and mostly touching, interspaces reduced to very short sharp ridges; punctures on gena similar to vertex but becoming progressively sparser and shallower below. Scape shagreened with very small deep punctures. Most of mesosoma punctured like frons; interspaces flattened on metanotum; punctures shallower and partially fused on dorsal faces of propodeum; interspaces slightly wider on dorsal half of mesepisternum and becoming very wide posteroventrally, epicnemium and mesosternum shagreened with few shallow punctures on posterior margin; metaepisternum shagreened and slightly shiny, with fine transverse striae on dorsal plate and few punctures on lower plate; posterior and lateral faces of propodeum with fine oblique striae and sparse shallow punctures. T1 with rounded punctures, denser and deeper on disc and becoming shallower and much sparser on sides, anterior vertical face impunctate; T2 more finely punctured than T1, all interspaces equal to several puncture diameters, punctures becoming slightly deeper and denser in apical fifth; T3–6 matte and finely shagreened, micropunctures becoming progressively denser and macropunctures becoming sparser in apical tergites; S1 shiny, barely microsculptured on basal petiole, irregularly reticulate and punctate in posterior part; punctures on S2 deeper and sparser than on T2, interspaces shiny on disc and becoming matte on sides; S3–6 more finely sculpted than respective tergites. Head and mesosoma with short bristle-like setae, sparser and brassy on head and dorsal face of mesosoma, denser and silvery on rest of mesosoma and propodeum; clypeus with sparse brownish setae on disc and dense silvery pubescence along basal margin; metasoma with dust-like pubescence, rusty on tergites and paler on sternites, sparse erected short setae on T3–6 and S2–6, T1 with dense pale short setae and scattered long ones.

COLORATION. Black; following parts yellow: very narrow and irregular line along pronotal carina not reaching humeri, narrow apical bands on T1–2 and posterior corners of S2; following parts dark red: apex and carinae of mandible, oblique line on gena starting from occipital carina on vertex and reaching eye in lower third. Wings infuscate with bright brassy reflections.

Male
