Alloxysta pusilla (Kieffer, 1902)

( Figs 2S ; 3S )

Allotria (Allotria) pusilla Kieffer, 1902a: 13 .

MATERIAL EXAMINED. — (1♀). M9-SES1400 T 2-M2: 1♀. Deposited at MNHN.

DISTRIBUTION. — Species known from the Palaearctic (Ferrer-Suay et al. 2012a). Previously cited from France by Kieffer (1902a: 13) and De Gaulle (1908: 26).

HOSTS. — See Charipinae Worldwide Catalogue (Ferrer-Suay et al. 2012a).

DIAGNOSIS. — Alloxysta pusilla is characterized by: a closed radial cell, 2.7 × longer than wide in female ( Fig. 3S ) and 2.4 × in male, pronotal and propodeal carinae present, forming a plate; female antenna with rhinaria beginning from F3, F1 longer than pedicel and F2, F2 shorter than F3, and F3 shorter than F4 ( Fig. 2S ); male antenna with rhinaria beginning from F1, pedicel-F3 subequal in length, F4 longer than F3, F1-F3 slightly curved. Similar to A. pilipennis , but the two species can be differentiated by the proportions between flagellomeres in both male and female: F2 shorter than F 3 in A. pusilla female ( Fig. 2S ), versus F2 subequal to F 3 in A. pilipennis female ( Fig. 2P ); F1-F3 subequal in length and slightly curved in A. pusilla male, versus F1-F3 distinctly unequal and with all flagellomers uncurved in A. pilipennis male; proportions of radial cell 2.7 × longer than wide in A. pusilla female ( Fig. 3S ), versus 2.4 × in A. pilipennis female ( Fig. 3P ).
