Myrmozercon burwelli sp. nov. is described from arboreal nests of Polyrhachis flavibasis (Formicidae) from rainforests in southeast Queensland, Australia. Myrmozercon beardae sp. nov. is described from unknown ants from South Australia. New specimens with host species data are recorded for Myrmozercon iainkayi Walter, and its protonymph and deutonymph are described. Supplementary notes are prov...

We report the occurrence of natural enemies of Plutella xylostela (L.) in organically farmed kale in Pernambuco, Brazil. Seven natural enemies were observed parasitizing or preying on larvae and pupae of P. xylostella--three parasitoids: Cotesia plutellae Kurdjumov (Hym.: Braconidae), Conura pseudofulvovariegata (Becker) (Hym.: Chalcididae) and Tetrastichus howardi (Olliff) (Hym.: Eulophidae), ...

The data on the fauna and biotopic distribution of ants (Hymenoptera, Formicidae) in yew-boxwood grove Caucasian State Natural Biosphere Reserve are presented. A total 27 ant species were identified, belonging to 17 genera 4 subfamilies ( Dolichoderinae , Ponerinae Formicinae Myrmicinae ). – Lasius F. Temnothorax Mayr richest include 5 each. For grove, all presented for first time.

We present a large-scale molecular phylogeny of the ants (Hymenoptera: Formicidae), based on 4.5 kilobases of sequence data from six gene regions extracted from 139 of the 288 described extant genera, representing 19 of the 20 subfamilies. All but two subfamilies are recovered as monophyletic. Divergence time estimates calibrated by minimum age constraints from 43 fossils indicate that most of ...

Pseudoponera stigma (F.) and Pseudoponera gilberti (Kempf) (Hymenoptera: Formicidae) are closely related Neotropical ants, often misidentified due to their morphological similarities. These species also share behavioral and ecological characters. In this study, we examined cytogenetic approaches as a tool to aid identification of P. stigma and P. gilberti. Both numerical and morphological karyo...
