Chinese species of egg-parasitoids of the genera Oxyscelio Kieffer, Heptascelio Kieffer and Platyscelio Kieffer (Hymenoptera: Platygastridae s.l., Scelioninae)

To date, the known Chinese fauna of egg-parasitoids of the genus Oxyscelio Kieffer encompasses two species from the mainland – O. doumao Burks and O. nubbin Burks. Here we record eighteen species of Oxyscelio from collections in mainland China: O. arvi Burks, O. ceylonensis (Dodd), O. convergens Burks, O. cordis Burks, O. crebritas Burks, O. cuculli Burks, O. dermatoglyphes Burks, O. doumao Burks, O. florus Kononova, O. granorum Burks, O. intermedietas Burks, O. jugi Burks, O. kramatos Burks, O. longiventris Burks, O. naraws Kozlov & Lê, O. perpensus Kononova, O. planocarinae Burks, and O. striarum Burks. Oxyscelio is primarily found in the tropics, and most of these species are shared with Taiwan and southeast Asia. Three species previously known only from Japan, O. arvi, O. florus, O. perpensus, are shared. The Chinese species are recorded from Guangdong, Guangxi, Hainan, Hebei, Hunan, Shaanxi, Sichuan, Yunnan and Zhejiang as well as additional material from Taiwan. Heptascelio hamatus Masner & Johnson and Platyscelio pulchricornis Kieffer are both recorded from Hainan and Guangdong, as well as records of P. pulchricornis from Sarawak and Thailand

Platyscelio hits again: the first record of this genus in the Dominican Republic

After the presence of the genus Platyscelio was noticed and confirmed in the Neotropical realm, in this paper the genus is recorded from the Panamanian realm, in Dominican Republic. In the Neotropical realm Platyscelio is represented through P. africanus Risbec, previously considered as being present only in the Afrotropical realm, but in the Panamanian realm we found a different species – P. pulchricornis Kieffer

Sampling Terrestrial Arthropod Biodiversity: A Case Study in Arkansas

The Interior Highlands is a biodiversity hotspot, with at least 200 known endemic species, but is understudied compared to hotspots, such as the Southern Appalachians. In order to begin to rectify this issue, a nine month study was conducted from mid-March through early December at a 4 ha site at Steel Creek, Buffalo National River, in Newton County, Arkansas. Thirteen collecting methods were employed, including three colors of Lindgren funnel trap, five colors of pan trap, Malaise traps, canopy traps with upper and lower collectors, pitfall traps, and Berlese-Tullgren extraction of leaf litter, which resulted in the collection of 1311 samples during 17 collection events. Target groups, including Formicidae, Carabidae, Cerambycidae, Curculionoidea, Araneae, Isopoda, Mecoptera, Phasmida, Vespidae, Ixodidae, Phalangodidae, and select Diplopoda and Orthoptera were identified. This resulted in 47,481 specimens representing 706 species that were curated and identified, including 18 putatively undescribed species, 56 species that represented new state records, 15 non-native species, and three species of Carabidae endemic to the Interior Highlands, two of which (Rhadine ozarkensis and Scaphinotus infletus) were previously known only from the original type series. Collection data for four beetle taxa – Buprestidae, Carabidae, Cerambycidae, and Curculionoidea excluding Scolytinae – as well as all taxa combined were analyzed. Pitfall and Malaise traps were the most effective (define here as collecting the most species with fewest samples) combination of collection methods for Carabidae, Curculionoidea, and the combined taxa, while Malaise traps alone and Malaise or canopy traps and green Lindgren funnel traps were the most effective collection methods for Cerambycidae and Buprestidae, respectively. Color of Lindgren funnel traps was important when targeting Buprestidae and some Curculionoidea, but not Carabidae or Cerambycidae. Extrapolated rarefaction curves indicated that 300–600 samples were required per trap type (1000+ for pitfall traps) before species accumulation is saturated. Finally, four rarely collected specimens or species – a Temnothorax curvispinosus gynandromorph, Orussus minutus, Eudociminus mannerheimii, and Merope tuber – are treated individually in detail

Systematics of the parasitic wasp genus Oxyscelio Kieffer (Hymenoptera, Platygastridae s.l.), part III: African fauna

African species of Oxyscelio (Hymenoptera: Platygastridae s.l.) are revised. A total of 14 species are recognized, 13 of which are described as new: O. absentiae Burks, sp. n., O. galeri Burks, sp. n., O. gyri Burks, sp. n., O. idoli Burks, sp. n., O. intensionis Burks, sp. n., O. io Burks, sp. n., O. kylix Burks, sp. n., O. lunae Burks, sp. n., O. nemesis Burks, sp. n., O. pulveris Burks, sp. n., O. quassus Burks, sp. n., O. teli Burks, sp. n. and O. xenii Burks, sp. n. The genus Freniger Szabó, syn. n. is recognized as part of an endemic African species group of Oxyscelio with incomplete hind wing venation, and O. bicolor (Szabó), comb. n. is therefore recognized as the only previously described species of Oxyscelio from Africa. The O. crateris and O. cuculli species groups, previously known from southeast Asia, are represented in Africa by seven and one species respectively

DNA barcoding for molecular identification of the genus Oxyscelio (Hymenoptera, Scelionidae) from southern China, with descriptions of five new species

Species of the genus Oxyscelio Kieffer are egg parasitoids of Orthoptera. The genus is relatively diverse in China, with 34 described species. Some species of the genus are extremely morphologically similar and difficult to identify, especially in males. In this study, DNA barcoding based on sequences of the COI gene was used to discriminate Oxyscelio species from southern China. In total, 49 COI sequences belonging to 22 morphospecies were obtained. The COI sequences worked well for the identification of all the studied species, with intraspecific genetic distances ranging between 0 and 4.3%, while interspecific distances ranged between 7.1% and 19%. Based on both morphological and molecular analyses, five species are described as new: O. amalocarina Mo & Chen, sp. nov., O. apheles Mo & Chen, sp. nov., O. latheticus Mo & Chen, sp. nov., O. stenos Mo & Chen, sp. nov., and O. striae Mo & Chen, sp. nov

The Australasian and southwest Pacific species of Oxyscelio (Hymenoptera: Platygastridae s.l.) are revised. A total of 80 species are recognized as valid, 13 of which are redescribed: O. atricoxa (Dodd), O. concoloripes (Dodd), O. flavipes (Kieffer), O. grandis (Dodd), O. hyalinipennis (Dodd), O. magniclava (Dodd), O. mirellus (Dodd), O. montanus (Dodd), O. nigriclava (Dodd), O. nigricoxa (Dodd), O. rugulosus (Dodd), O. shakespearei (Girault), and O. solitarius (Dodd).
