Diagnosis

Alloxysta palearctica sp. nov. is mainly characterized by its completely open radial cell, pronotal carinae present, propodeal plate present, placodeal sensilla and club shape begin on F4, F1 equal to pedicel, F1 and F2 very bumped. The combination of these features easily distinguishes A. palearctica sp. nov. from other species of Alloxysta .

Etymology

This new species is named after the biogeographic region where it was collected.

Material examined

Holotype

JAPAN: ♂ [Hokkaido, Nukabira , 600 m, 5 Jul. 1989, sweep, M.J. Sharkey] ( CNCI C-215).

Description

LENGTH. Female: unknown. Male: 0.9 mm.

C OLORATION. Head, mesosoma and metasoma yellowish brown. Antenna yellowish slightly darkening towards the end. Legs yellow and veins yellowish brown.

HEAD. Transversely ovoid, smooth and shiny, slightly wider than high in front view. Setae below and between toruli, few scattered setae above toruli. Scattered setae on vertex and many setae on face. Transfacial line 0.8 times height of compound eye. Malar space 0.2 times height of compound eye.

ANTENNA. 14-segmented, filiform.All antennomeres covered with sparse setae. F1–F3 smooth and thinner than remaining flagellomeres, F4–F11 with placodeal sensilla and club shaped. Antennal formula: 4.5 (2.7); 4.5 (2.0); 4.4 (2.1); 4.0 (2.0); 4.8 (2.5); F4–F11 subequal in length, width and shape (Fig. 11.3).

MESOSOMA. Pronotum covered by few sparse setae, carinae present (Fig. 11.5). Mesoscutum smooth and shiny, round in dorsal view with few scattered setae. Scutellum smooth and shiny with scattered setae, more abundant on apex of scutellum. Propodeum covered by abundant pubescence, with two carinae forming a protruding plate, this plate has a few setae on anterior third (Fig. 11.7).

FORE WING. Longer than body, 1.4 times as long as mesosoma and metasoma together. Covered with dense pubescence; marginal setae present and very long (Fig. 11.1). Completely open radial cell, 2.3 times as long as wide. R1 short and curved; Rs long and slightly curved (Fig. 11.4).

METASOMA. Anterior part with an incomplete ring of setae, glabrous at center, wider laterally. Metasoma smooth and shiny, T3 and T4 clearly distinguished.

Distribution

Eastern Palaearctic: Japan.
