Diagnosis

Alloxysta pascuali sp. nov. is mainly characterized by a completely open radial cell; the presence of pronotal carinae and a propodeal plate; antenna with placodeal sensilla, club shape beginning on F4, and F1 shorter than pedicel. The combination of these features readily distinguishes A. pascuali sp. nov. from its congeners.

Etymology

This new species is dedicated to Pascual Mas Palomares, brother-in-law of the first author, who wants to thank him for his constant support.

Description

LENGTH. Female: 0.82–0.99 mm. Male: unknown.

COLORATION. Head, mesosoma and metasoma yellowish brown. Scape, pedicel, F1–F3 dark yellow, F4- F11 yellowish brown. 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 0.5 times height of compound eye.

ANTENNA. 13-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: 3.5 (2.0); 2.5 (1.3); 2.0 (1.3); 2.0 (1.3); 2.8 (2.0); F4–F11 subequal in length, width and shape (Fig. 12.3).

MESOSOMA. Pronotum covered by sparse setae, fewer in distolateral corners and abundant on anterior margins, with two long and curved carinae present (Fig. 12.2). 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 wide and protruding plate, this plate has a few setae on anterior half (Fig. 12.5).

FORE WING. Longer than body, 1.3 times as long as mesosoma and metasoma together. Covered with dense pubescence; marginal setae present and very long (Fig. 12.1). Completely open radial cell, 2.0 times as long as wide. R1 short and almost straight; Rs long and slightly curved (Fig. 12.1).

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: Germany, Japan.
