Abstract: Leaf-cutter ant nests attract a wide variety of guests and parasites due to considerable food resources, substrate and shelter available within nests. Limited information is known about their taxonomy, bionomics, and natural history, including interactions with the ants, and degree of host specificity of these symbionts. Here we describe two new species of Szelenyiopria Fabritius, 1974 (Diapriidae, Diapriinae, Diapriini) wasps which are koinobiont endoparasitoids of the larvae of a leaf-cutter ant, Acromyrmex coronatus (Fabricius, 1804) (Myrmicinae, Attini) in Chiriquí, Panama. For both new Szelenyiopria species, S. fortunensis Araúz & Fernández-Marín, sp. nov. and S. chiriquiensis Araúz & Fernández-Marín, sp. nov., we provide information on parasite–host interactions. The most abundant and frequent parasitoid type was solitary, while gregarious parasitoidism, where two or more wasps emerged from a single ant larva, was associated with certain times of the year. We provide an updated key to females of all species of Szelenyiopria, their geographic distribution, and host–parasite interactions. Szelenyiopria previously had been identified as parasitoids of several ant genera including some Acromyrmex species, but our data indicate that some species of Szelenyiopria may be specialized on A. coronatus ants. Rates of parasitism suggest that the wasps have a negative effect on colonies and populations of the ants.

Abstract: This study provides a comprehensive overview of the genus Zygota Förster combining DNA barcoding and current morphology. Nineteen species of Zygota were found throughout Germany, including the newly described species Zygota walli sp. nov. First species records for Germany are: Zygota balteata Macek, 1997; Z. comitans Macek, 1997; Z. spinosipes (Kieffer, 1908); Z. sordida Macek, 1997; Z. angularis Macek, 1997 and Z. vigil Nixon, 1957. We also clarify diagnoses for the two related genera, Pantoclis Förster and Zygota to designate the boundaries of the Zygota genus and propose new synonymies: Zygota caligula Buhl, 1997 is a junior synonym of Z. congener (Zetterstedt, 1840); Z. reticulata Kozlov, 1978 is a junior synonym of Z. ruficornis (Curtis, 1831). Thirteen species of Zygota sensu Nixon (1957) are transferred to the genus Pantoclis with the following new combinations proposed: Zygota brevinervis (Kieffer, 1908) (= Pantoclis brevinervis (Kieffer, 1909), comb. nov.); Z. brevipennis (Kieffer, 1908) (= P. brevipennis (Kieffer, 1908), comb. nov.); Z. caecutiens (Kieffer, 1908) (= P. caecutiens (Kieffer, 1908), comb. nov.); Z. cursor (Kieffer, 1908) (= P. cursor (Kieffer, 1908), comb. nov.); Z. fossulata (Thomson, 1858) (=P. fossulata (Thomson, 1858), comb. nov.); Z. fuscata (Thomson, 1858) (= P. fuscata (Thomson, 1858), comb. nov.); Z. hemiptera (Thomson, 1858) (= P. hemiptera (Thomson, 1858), comb. nov.); Z. microtoma (Kieffer, 1909) (= P. microtoma (Kieffer, 1909), comb. nov.); Z. soluta (Kieffer, 1907) (= P. soluta (Kieffer, 1907), comb. nov.); Z. striata (Kieffer, 1909) (= P. striata (Kieffer, 1909), comb. nov.); Z. subaptera (Thomson, 1858) (= P. subaptera (Thomson, 1858), comb. nov.); Z. sulciventris (Kieffer, 1909) (= P. sulciventris (Kieffer, 1909), comb. nov.), and Z. unicolor (Kieffer, 1908) (= P. unicolor (Kieffer, 1908), comb. nov.).

Abstract: This paper reviews the status of Geodiapria and its nominotypical and only included species G. longiceps. Geodiapria was previously understood to be very similar to, and doubtfully separated from the genus Basalys. We use integrative taxonomy (morphology, DNA-barcoding, phylogenetic tree building) to show that the valid name for what was G. longiceps Kieffer, 1911 is now Basalys rufocinctus (Kiefer, 1911) and that Geodiapria is consequently a junior synonym of Basalys syn. nov. The following taxa are new synonyms of B. rufocinctus: Loxotropa longiceps Wasmann, 1909, syn. nov., G. longiceps Kieffer, 1911, syn. nov., L. rufosignata Kieffer, 1911, syn. nov. Basalys rufocinctus is newly reported from Corsica, Germany, Norway and Spain.

Abstract: A new species of the parasitic wasp Coptera Say was previously distinguished from other species via correspondence between ecological (host) differences and DNA barcodes. A description and figures for Coptera tonic sp. nov., along with revisions to existing keys that allow it to be distinguished from other Nearctic species without the aid of molecular characters, is provided in this work.

Abstract: A new species of Calogalesus Kieffer, 1912, C. sinicus sp. n., is described and illustrated, collected from a Chinese prickly ash (Zanthoxylum bungeanum Maxim.) orchard in Yunnan province of China. This is the third described species of the genus in the World. The new species can be distinguished from the other two described Calogalesus species by the head profile, proportions of the antennal segments, tridentate mandible, and mandible length. A key to World species of the genus is provided.

Abstract: The genus Ismarus Haliday, 1835 from China is revised for the first time. Three species from Oriental region of China are described and illustrated as new species: Ismarus longus sp. n., Ismarus nigritrochanter sp. n. and Ismarus parvicellus sp. n., with two species: Ismarus dorsiger (Halidy, 1831) and Ismarus halidayi Foerster, 1850 are newly recorded from Chinese fauna. A key to the Chinese species is provided. All type specimens are deposited in the Hymenoptera Collection of South China Agricultural University, Guangzhou (SCAU).
