Revision of the western Palaearctic species of Aleiodes Wesmael (Hymenoptera, Braconidae, Rogadinae). Part 1: Introduction, key to species groups, outlying distinctive species, and revisionary notes on some further species.

ABSTRACT: Seven new species of the genus Aleiodes Wesmael, 1838 (Braconidae: Rogadinae) are described and illustrated: Aleiodes abraxanaesp. n., Aleiodes angustipterussp. n., Aleiodes artesiariaesp. n., Aleiodes carminatussp. n., Aleiodes diarsianaesp. n., Aleiodes leptofemursp. n., and Aleiodes ryrholmisp. n. A neotype is designated for each of Aleiodes circumscriptus (Nees, 1834) and Aleiodes pictus (Herrich-Schäffer, 1838), and both species are redescribed and illustrated. Aleiodes ochraceus Hellén, 1927 (not Aleiodes ochraceus (Curtis, 1834)) is renamed as Aleiodes curticornisnom. n. & stat. rev., and redescribed and illustrated. Aleiodes bistrigatus Roman, 1917, Aleiodes nigriceps Wesmael, 1838, and Aleiodes reticulatus (Noskiewicz, 1956), are re-instated as valid species. A lectotype is designated for Aleiodes bistrigatus Roman. An illustrated key is given to some distinctive species and the residual species groups along which further parts of an entire revision of western Palaearctic species of Aleiodes and Heterogamus will be organised. Biology, host associations and phenology are discussed for the keyed species (in addition to the above, Aleiodes albitibia (Herrich-Schäffer, 1838), Aleiodes apiculatus (Fahringer, 1932), Aleiodes arcticus (Thomson, 1892), Aleiodes cantherius (Lyle, 1919), Aleiodes esenbeckii (Hartig, 1834), Aleiodes jakowlewi (Kokujev, 1898), Aleiodes modestus (Reinhard, 1863), Aleiodes nigricornis Wesmael, 1838, Aleiodes pallidator (Thunberg, 1822), Aleiodes praetor (Reinhard, 1863), Aleiodes seriatus (Herrich- Schäffer, 1838) sensu lato, Aleiodes testaceus (Telenga, 1941), Aleiodes ungularis (Thomson, 1892), and Aleiodes varius (Herrich-Schäffer, 1838)) which are dealt with in full here (with the exception of Aleiodes seriatuss.l. which is, however, included in the key). The experimental methodology covering the revision as a whole, which involves some behavioural investigation, is outlined.

Project description:Aleiodes Wesmael is the most diverse rogadine genus worldwide, with specialized koinobiont endoparasitic development in Lepidoptera caterpillars resulting in mummification of the host remains. This paper focuses on describing new Aleiodes species from the Yanayacu Biological Station, with special interest in those with biological information. We describe 24 new species (Aleiodes albidactyl sp. n., Aleiodes albigena sp. n., Aleiodes albiviria sp. n., Aleiodes bimaculatus sp. n., Aleiodes cacuangoi sp. n., Aleiodes colberti sp. n., Aleiodes delicatus sp. n., Aleiodes dyeri sp. n., Aleiodes elleni sp. n., Aleiodes falloni sp. n., Aleiodes frosti sp. n., Aleiodes kingmani sp. n., Aleiodes longikeros sp. n., Aleiodes luteosicarius sp. n., Aleiodes marilynae sp. n., Aleiodes mirandae sp. n., Aleiodes napo sp. n., Aleiodes nubicola sp. n., Aleiodes onyx sp. n., Aleiodes shakirae sp. n., Aleiodes stewarti sp. n., Aleiodes townsendi sp. n., Aleiodes tzantza sp. n., and Aleiodes yanayacu sp. n.) from Napo Province in Ecuador, 16 of which were reared from host caterpillars. With these results 89 species of Neotropical Aleiodes are now known, with 41 of them having host records. The most commonly reared species were in the circumscriptus/gastritor species-group, and mostly associated with Geometridae hosts (six of ten species). Three species of seriatus species-group, in contrast, were each reared from a different family. One of these species (i.e. A. frosti sp. n.), reared from Notodontidae, cuts a posterior radial opening in the mummy for emergence, a unique behavior in Aleiodes, recorded here for the first time. A. luteosicarius sp. n. is the first described species from Ecuador in the pallidator species-group. Differing from previously described pallidator species, which attack only Lymantriinae larvae, A. luteosicarius sp. n. attacks several species of Arctiinae larvae, being both subfamilies within Erebidae with densely setose caterpillars. We also describe new species of the gressitti and pulchripes species-groups.
