Fig. 1A–B

Diagnosis

Species very similar to A. eucharoides , from which it can be distinguished by always having a completely smooth mesoscutum and scutellum, strongly carinate notauli, with a short median scutellar carina at scutellar apex (mesoscutum and notauli weakly carinate in some specimens of A. eucharoides while smooth in others, the scutellum is alutaceous and lacks median carina).

Redescription

LENGTH. Body: 4.4 mm. Antennae: 3.5 mm (♀), 3.6 mm (♂). Wings: 4.1 mm.

COLORATION. Head, mesosoma and metasoma black. Mandibles yellowish brown with darker teeth. Antennae dark brown with first segment black. Legs yellowish brown with black coxae. Veins of wings brownish.

HEAD. Triangular-shaped in anterior view. Face smooth, punctate, covered with sparce white setae. Width of head 2.3 times its length in dorsal view while in anterior view, 1.2 times its height. Malar sulcus coriaceous, 0.7 times height of compound eye. Transfacial line length 1.1 times height of compound eye. Diameter of toruli larger than inter-toruli distance and torulus to compound eye distance. Clypeus smooth, glabrous, shortly convex, almost unnoticeable. Occipital and postocular carinae absents. Compound eyes glabrous. In females POL:OOL:LOL ratio = 8.5:7.5:4, ocelli diameter being 2.5; in males POL:OOL:LOL ratio = 8:6:5, ocelli diameter being 3. Frons and gena smooth, shiny and glabrous; occiput smooth and shiny with sparse setae.

ANTENNAE. Cylindrical flagellomeres covered with pubescence. Female antennal formula: 12(4), 4.5(3.5), 14(3), 14(3), 12(3), 12(3), 12(3), 11(3), 10(3), 10(3), 9(3), 8(3), 13(3). Male antennal formula: 9(4), 4(3.5), 13(3.5), 12.5(3.5), 12(3.5), 11.5(3.5), 10(3), 10(3), 10(3), 10(3), 9(3), 9(3), 9(3), 13(3). Placodeal sensilla starting at F1 and abundant in all flagellomeres in both sexes.

MESOSOMA. Pronotum smooth and pubescent, with some oblique carinae in ventral region ( Fig. 1B ). Mesoscutal width 1.1 times its length in dorsal view. Mesoscutum smooth and shiny; almost glabrous except for a few setae. Notauli complete with transverse carinate sculpture; median mesoscutal furrow short and almost not present ( Fig. 1A ). Lateral region of mesoscutum smooth; parapsidal signum and parascutal sulcus absent, with a line of dense pubescence instead. Scutellar length 0.7 times that of mesoscutum in dorsal view. Scutellum smooth and shiny ( Fig. 1A ). Scutellar foveae triangular, smooth, basally defined by a carina; lateral pits of scutellar foveae present, but weakly excavated. Interfoveal line present, shortly extended into scutellum. Short median scutellar carinae present at scutellum apex. Circumscutellar carina complete, clearly defined, slightly dorsally projected at scutellar apex. Mesopleuron completely smooth, glabrous and shiny, with internally carinate transverse groove; carinae more abundant in posterior region; mesopleural triangle presents dense pubescence. Metanotal troughs heavily pubescent, smooth, densely covered by short hyaline hairs. Propodeum smooth, heavily pubescent, divided into large cells; median propodeal cell present, occupying ⅔ of upper propodeum, rest of propodal surface divided into irregular, smaller cells.

WINGS. Pubescent. Radial cell of forewing closed, 2.9 as long as wide. Marginal pubescence of forewing denser at apical third.

METASOMA. Longer than head + mesosoma. Petiole, smooth, shiny about 2.0 times as long as metacoxa. Third metasomal tergum 2.3 times longer than fourth tergum in dorsal view. Fifth, sixth, seventh metasomal terga visible in dorsal view. Metasomal terga smooth and glabrous, not punctate.

Biology

Unknown.

Distribution

Palaearctic. Known from Tajikistan ( Belizin 1951); first citation for Japan.
