Alloxysta citripes ( Thomson, 1862)

( Figs 2G View FIG ; 3G View FIG ; 6F View FIG )

Allotria citripes Thomson, 1862: 410 .

MATERIAL EXAMINED. — (11♀). M9-BOR1400- T2 -M1: 1♀ ; M9- SES1400- T1 -M2: 1♀ ; M9-SES1400- T2 -M2: 1♀ ; M9-SES1400- T3 - M2: 1♀ ; M9-SES1400- T4 -M2: 1♀ ; M9-SES1400- T6 -M2: 1♀ ; M9-SES2000- T4 -M1: 2♀ ; M9-SES2000- T2 -M2: 2♀ ; M10- CAI2000- T4 -M1: 1♀. Material deposited at MNHN except for 5♀ deposited at UB .

DISTRIBUTION. — Species known from the Palaearctic region (Ferrer- Suay et al. 2012a). Previously cited from France by Kieffer 1904a: 600 and De Gaulle 1908: 26.

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

DIAGNOSIS. — Alloxysta citripes is characterized by its partially open and small radial cell being 2.1 × longer than wide ( Fig. 3G View FIG ), pronotal carinae present, propodeal carinae present forming a plate but not protruding, female antenna with rhinaria beginning from F4, F1 subequal to pedicel and longer than F2, F2-F4 subequal in length ( Fig. 2G View FIG ), male antenna with rhinaria beginning from F1, pedicel-F3 subequal, F3 slightly shorter than F4. Similar to Alloxysta postica ( Hartig, 1841) but the two species can be differentiated by the shape of propodeal carinae: the carinae are not protruding in A. citripes ( Fig. 6F View FIG ), whereas they are clearly visible and forming a plate in A. postica ; proportions of radial cell: 2.1 × longer than wide in A. citripes ( Fig. 3G View FIG ), versus 2.5 × in A. postica ( Fig. 3Q View FIG ).

Alloxysta consobrina ( Zetterstedt, 1838) ( Figs 2I View FIG ; 3I View FIG )

Cynips consobrina Zetterstedt, 1838: 410 .

MATERIAL EXAMINED. — (16♀). M09-BOR2000- T4 -M1: 1♀ ; M09-SES1400- T1 -M2: 4♀ ; M09-SES1400- T2 -M2: 7♀ ; M09-SES1400- T3 -M2: 2♀ ; M09-SES1400- T6 -M2: 1♀ ; M10- CAI2000- T1 -M1: 1♀. Eight ♀ deposited at MNHN and 8♀ at UB .

DISTRIBUTION. — Cosmopolitan. Previously cited from France by Kieffer (1902a: 16) and De Gaulle (1908: 26). Alloxysta consobrina was previously cited in France as Alloxysta fuscicornis ( Hartig, 1841) , a well-known cosmopolitan species. These two homonymous species were recently synonymized by Ferrer-Suay et al. (2013).

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

DIAGNOSIS. — Alloxysta consobrina is characterized by: radial cell 2.7 × longer than wide ( Fig. 3I View FIG ), pronotal carinae present, propodeal carinae absent, male and female antenna with rhinaria beginning from F4, F2 longer than F3, F3 shorter than F4 ( Fig. 2I View FIG ), F1-F3 bowed in male. Similar to A. circumscripta , but the two species can be differentiated by the proportion between flagellomeres: F1 longer than F2, F2 subequal to F 3 in A. consobrina ( Fig. 2I View FIG ), versus F1 subequal to F2, F2 shorter or subequal to F 3 in A. circumscripta ( Fig. 2F View FIG ); proportions of radial cell: 2.7 × longer than wide in A. consobrina ( Fig. 3I View FIG ) but 2.5 × in A. circumscripta ( Fig. 3F View FIG ).

Alloxysta fracticornis ( Thomson, 1862) ( Figs 2H View FIG ; 3H View FIG )

Allotria fracticornis Thomson, 1862: 408 .

MATERIAL EXAMINED. — (2♂ & 8♀). M9-BOR1400- T4 -M1: 1♂ ; M9-SES1400- T3 -M2: 2♀ ; M9-SES1400- T6 -M2: 1♀ ; M9- SES2000- T2 -M1: 1♂ ; M9-SES2000- T4 -M1: 2♀ ; M9-SES2000- T5 - M1: 2♀ ; M9-SES2000- T3 -M1: 1♀. Material deposited at MNHN except for 1♂ & 4♀ deposited at UB .

DISTRIBUTION. — Previously known from the Palaearctic region (Ferrer-Suay et al. 2012a). First record from France.

HOSTS. — Unknown.

DIAGNOSIS. — Alloxysta fracticornis is characterized by its closed radial cell being 2.2 × longer than wide ( Fig. 3H View FIG ), pronotal carinae absent, propodeal carinae present, male and female with rhinaria beginning from F3, F1-F3 subequal in length ( Fig. 2H View FIG ), F3 curved in male. Similar to Alloxysta mullensis ( Cameron, 1883) , but the two species can be differentiated by the ratio between F1 and pedicel: F1 longer than pedicel in A. fracticornis ( Fig. 2H View FIG ), versus F1 subequal to pedicel in A. mullensis ( Fig. 2M View FIG ); F1-F3 subequal in length in A. fracticornis ( Fig. 2H View FIG ) but F1 longer than F2 and F2 subequal to F 3 in A. mullensis ( Fig. 2M View FIG ); male antenna with F3 curved in A. fracticornis but without any curved flagellomere in A. mullensis .

Alloxysta franca

Ferrer-Suay & Pujade-Villar, n. sp. ( Fig. 7 View FIG )

TYPE MATERIAL. — (1♀). Holotype ♀ deposited at MNHN with the following labels: M09-BOR2000- T1 -M1, Valdeblore, Col de Salèse , larch forest, Alt: 2058 m, 10-24.VI.2009.

ETYMOLOGY. — The new species is named after the country where it was first found, France.

DISTRIBUTION. — France.

HOSTS. — Unknown.

DIAGNOSIS. — Alloxysta franca Ferrer-Suay & Pujade-Villar , n. sp. is characterized by its completely open radial cell being 2.4 × longer than wide, pronotal carinae absent, propodeal carinae forming a plate, female antenna with rhinaria beginning from F4, F1 longer than F2, F2 subequal in F3, F3 shorter than F4. Similar to Alloxysta pilae Ferrer-Suay n. sp., but the two species can be differentiated by the pronotal carinae: absent in A. franca Ferrer-Suay & Pujade-Villar , n. sp., but present in A. pilae Ferrer- Suay, n. sp.; proportions of radial cell: 2.4 × longer than wide in A. franca Ferrer-Suay & Pujade-Villar , n. sp., vs 2.2 × in A. pilae Ferrer-Suay , n. sp.
