Chrysidea pumiloides Zimmermann, 1956 and its Malagasy allies are taxonomically revised. As a result, C. pumiloides and C. phoebe Zimmermann, 1956 are redescribed; two new species, C. vazimba sp. nov. and C. merina sp. nov., are described from museum collections, and another new species, C. rioae sp. nov., is described based on a male recently collected in Southern Madagascar, at Berenty Reserve. The habitus of the holotypes and the male genitalia are illustrated and the key to Malagasy Chrysidea Bischoff, 1913 is updated.
Revision of the genus Spilopteron Townes, 1965 (Hymenoptera: Ichneumonidae: Acaenitinae) from Japan
(2017)
Ten Japanese species of the genus Spilopteron Townes, 1965 are recognized. Five new species, S. albiventre sp. nov., S. brachyurum sp. nov., S. nigrum sp. nov., S. oblongulum sp. nov. and S. pseudonigrum sp. nov., are described from Japan. Morphological discrimination between most Japanese species is confirmed by sequence analysis of the mitochondrial COI gene, which indicates the following relationships: S. oblongulum sp. nov. + S. apicale (Matsumura, 1912), S. brachyurum sp. nov. + S. nigrum sp. nov. + S. pseudonigrum sp. nov., and S. tosaense (Uchida, 1934) + S. luteum (Uchida, 1930). A key to the Japanese species of Spilopteron is provided. This genus seems to have its center of diversity in the mid-latitude area of East-Asia.
A new cryptic species, Aleochara (Xenochara) castaneimarmotae Klimaszewski, Webster, and Brunke, new species (Coleoptera: Staphylinidae: Aleocharinae), associated with Marmota monax (Linnaeus) burrows and caves in eastern North America, is described and illustrated. A key to Canadian species of subgenus Xenochara Mulsant and Rey and revised distributions of the taxonomically difficult fumata species group are provided. Aleochara quadrata Sharp is recorded from Washington and Oregon for the first time.
The monotypic Neotropical genus Ectophasiopsis Townsend, 1915 (Diptera, Tachinidae, Phasiinae) is revised, with the addition of two species (one new and another transferred species), and a redefinition of the genus, accompanied by photographs and drawings of specimens and male terminalia. A new combination is proposed, Ectophasiopsis gradata (Wiedemann, 1830) comb. nov., previously Trichopoda Berthold, 1827, and a new species Ectophasiopsis ypiranga sp. nov. is described. A key for the genera of the “Trichopoda typica” subgroup sensu Sabrosky (1950), as well as a key to species of Ectophasiopsis is given. The geographical range of the genus and the host list are updated.
The paper provides the first illustrated key to all described genera of Ceinae, i.e., Bohpa Darling, 1991, Cea Walker, 1837, and Spalangiopelta Masi, 1922. Based on the study of the original material, the genus Diparisca Hedqvist, 1964 stat. nov. is removed from the synonymy with Spalangiopelta and its higher classification is discussed. Spalangiopelta rameli sp. nov. and S. viridis sp. nov. are described from Greece and the Canary Islands, respectively.
The nine British and Irish species of Enicospilus are revised, mapped and an identification key provided. One species, Enicospilus myricae sp. nov., is described as new; Enicospilus merdarius (Gravenhorst, 1829) is a senior synonym of E. tournieri (Vollenhoven, 1879) syn. nov.; the only available name for E. merdarius auctt. is Enicospilus adustus (Haller, 1885) stat. rev., and a neotype is designated for Ophion adustus Haller, 1885. Enicospilus cerebrator Aubert, 1969 and E. repentinus (Holmgren, 1860) are newly recorded from Britain. Some host data are available for eight of the nine species.
We have been surveying a gypsy moth, Lymantria dispar (Lep., Lymantriidae), population in the oak forest of Klingenbach near Eisenstadt, Austria, since 1992. During the last gradation from 1993 to 1996, we studied the natural enemy complex at this site in comparison with other locations where no outbreak occurred (HOCH et al. 2001). During the latency years, an experimental study on the impact of predators on L. dispar pupal populations was performed (GSCHWANTNER et al. 2002). The population density was recorded regularly; in the winter 2001/02, the egg mass surveys indicated a rising population after seven years of latency. We used this opportunity to study the parasitoid complex in the progradation phase. This phase of gypsy moth population dynamics was not studied in our previous work. Moreover, it allowed us to repeat the investigation during the outbreak after 11 years.
