Abstract
Hartig’s collection of Alloxysta species, deposited in the Zoologische Staatssammlung Museum (ZSM, Munich, Germany), is here reviewed. In total, 19 species and 144 specimens have been studied. Fourteen species, of the previous twenty-two, are now valid: Alloxysta aperta (Hartig, 1841), A. brachyptera (Hartig, 1840), A. castanea (Hartig, 1841), A. circumscripta (Hartig, 1841), A. fuscicornis (Hartig, 1841), A. leunisii (Hartig, 1841), A. longipennis (Hartig, 1841), A. macrophadna (Hartig, 1841), A. melanogaster (Hartig, 1840), A. obscurata (Hartig, 1840), A. pilipennis (Hartig, 1840), A. postica (Hartig, 1841), A. minuta (Hartig, 1840) and A. rufiventris (Hartig, 1840). These species are redescribed and their morphological features are illustrated in corresponding plates. Alloxysta cursor (Hartig, 1840) and A. erythrothorax (Hartig, 1840) are considered as ‘nomen dubium’. Two new synonyms are here established among Hartig’s species: Alloxysta defecta (Hartig, 1841) with A. castanea (Hartig, 1841) and A. flavicornis (Hartig, 1841) with A. pilipennis (Hartig, 1840). Additional material of Alloxysta deposited in this museum has been examined and new host records are here reported.
Highlights
Charipinae (Hymenoptera: Cynipoidea: Figitidae) are small wasps (0.8−2.0 mm), which are typically characterized by having a smooth and shiny body, and by being widely distributed around the world
The type material of Alloxysta erythrothorax was lost when Evenhuis (1982) studied the Alloxysta type http://rcin.org.pl specimens of the ZSM
After examination of the type material (Ferrer-Suay et al 2012b), we showed that this species was erroneously synonymized with A. brassicae (As). brevis by Fergusson (1986)
Summary
Charipinae (Hymenoptera: Cynipoidea: Figitidae) are small wasps (0.8−2.0 mm), which are typically characterized by having a smooth and shiny body, and by being widely distributed around the world. Emargininae differs from Charipinae having a deeply bilobed forewing, and most species having two faint semi-parallel scutellar dorsal carinae, slightly ovoid. Menke & Evenhuis (1991) subsequently conducted a review of the Charipinae species in North America with some descriptions of new species and new combinations. The taxonomy of this subfamily has been chaotic in the past. The early authors gave special attention to size and colouration of specimens, disregarding other important characters that are considered as essential for species differentiation, namely: a) the proportion of the flagellomeres; b) the size and shape of the radial cell; c) the presence or absence of pronotal carinae; d) the presence or absence, size and shape of propodeal carinae
