We revised the species of the genus Pristomerus Curtis, 1836 in the Afrotropical Region. Fortynine species are recognized, of which 31 are newly described. The following new species are described: P. afrikaner, P. aka, P. babinga, P. bemba, P. dikidiki, P. herero, P. hutu, P. kagga, P. khoikhoi, P. kuku, P. masai, P. mbaka, P. mbama, P. mboum, P. nzakara, P. protea, P. restio, P. san, P. sara, P. sotho, P. swahili, P. teke, P. tutsi, P. venda, P. wolof, P. xhosa, P. yakoma, P. yangere, P. yoccolo, P. zande and P. zulu spp. nov. New synonyms: P. africator, P. cunctator and P. luteolus are new junior synonyms of P. pallidus. New records: new host records are reported for the widespread P. pallidus; new country-level distribution records are added for P. bullis, P. keyka, P. kelikely and P. pallidus; and reports of Trathala concolor and P. veloma in South Africa are shown to have been erroneous. An illustrated dichotomous key to females is provided; an online Lucid interactive matrix key is also available at www.waspweb.org. Finally, the ecological and geographical correlates of colour patterns exhibited by Pristomerus in the Afrotropical region are discussed.
The genus Cotesia Cameron, 1891 is one of the most diverse of the Microgastrinae, a subfamily of wasps that are exclusively endoparasitic on lepidopteran larvae. Species of Cotesia are widely utilised as biological control agents across the world. In Australia, there are currently 10 confirmed native species as well as four species introduced for the management of lepidopteran pests. The genus is morphologically conserved and has not been studied in the Australasian region for many decades. In this study, we use both comparative morphology and sequence data from the COI gene to delineate species, and in so doing describe seven new species from Australia: C. lasallei sp. nov., C. medusae sp. nov., C. ocellata sp. nov., C. reidarum sp. nov., C. scripta sp. nov., C. tjapekki sp. nov. and C. wonboynensis sp. nov., raising the number of species of Cotesia formally recorded in Australia to 21. We also provide updated descriptions of the previously described native species, diagnoses for the introduced species and a key to all currently described species found on the continent and from Papua New Guinea. This study treats only a fraction of the likely diversity of Cotesia, but provides a solid framework for future work.
Four new species of the braconid wasp genus Hecabolus Curtis, 1834 (Doryctinae Foerster, 1863) are described for the Neotropical region in south and southwestern Brazil: H. acutus sp. nov., H. chrisaxeli sp. nov., H. gavinbroadi sp. nov., and H. transversalis sp. nov. We also report the morphological variation of females and males of H. mexicanus Zaldívar-Riverón & Belokobylskij, 2009, originally described based on a single female, and provide its first precise geographical distribution records. An updated key to the 13 described species of Hecabolus is provided.
