A new species of Xorides Latreille (Hymenoptera,Ichneumonidae, Xoridinae) parasitizing Pterolophia alternata (Coleoptera,Cerambycidae) in? Robinia?pseudoacacia

A new species is described, Xorides benxicus Sheng, sp. n., reared from the cerambycid twig-boring pest of Robinia pseudoacacia Linnaeus, Pterolophia alternata Gressitt, 1938, in Benxi County, Liaoning Province, China. A key is given to the species similar to Xorides benxicus Sheng, namely Xorides asiasius Sheng & Hilszczański, 2009, Xorides cinnabarius Sheng & Hilszczański, 2009 and Xorides sapporensis (Uchida, 1928).     

A new species of the genus Seticornuta Morley (Hymenoptera,Ichneumonidae, Metopiinae) from South Korea

Old World species of the genus Seticornuta Morley are reviewed. Seven species of this genus were recorded worldwide, but only one species, Seticornuta albopilosa (Cameron), was known from the Old World. Here, we report one new species, Seticornuta koreana sp. n., from South Korea, and redescribe the other known Old World species, Seticornuta albopilosa, with photographs.     

Two new species of the genus Probles Förster (Hymenoptera: Ichneumonidae: Tersilochinae) from South Korea and Russian Far East

Two species of the genus Probles Förster, P. interruptor sp . nov . and P. segaza sp . nov ., from South Korea and Russian Far East, are described. Probles interruptor differs from its congeners by occipital carina mediodorsally narrowly interrupted and polished occipital surface extending partly on the vertex. Probles segaza differs from other species of Euporizon by its robust ovipositor with a deep and narrow dorsal subapical notch.     

Disjunctive distribution of the basal genus Aplomerus (Hymenoptera: Ichneumonidae: Xoridinae) in East Asia and North America,with a new species from Japan

The first Japanese representative of the predominantly Nearctic genus Aplomerus Provancher, A. japonicus sp. nov., is described. This species can easily be distinguished from the other species by the black body. Morphologically this species resembles A. lineatulus (Say) from eastern North America but is separable by the sculpture of the propodeum and third metasomal tergite. The discovery of this species demonstrates a disjunctive distribution of the genus Aplomerus in East Asia and North America. Notes on habitat and adult behavior are also given.     

Two new records of the genus Cryptaphis Hille Ris Lambers (Hemiptera: Aphididae) from Korea

The genus Cryptaphis Hille Ris Lambers 1947 is described for the first time in Korea with new records of two species, Cryptaphis geranicola (Shinji 1935) and Cryptaphis menthae Takahashi 1961. Cryptaphis geranicola was collected from Geranium thunbergii (Lamiaceae) and C. menthae was collected from Isodon inflexus (Lamiaceae). Important characteristics are re-described, illustrated, and measured in apterous and alate viviparous females.

Two new species of the genus Chablisea Gauld et Dubois (Hymenoptera: Ichneumonidae: Pimplinae) from Vietnam

Two new species of the genus Chablisea Gauld et Dubois, 2006 are described from Vietnam based on ichneumonid material collected from 2002 to 2008. Chablisea condimenta sp. n. differs from other species of the genus by the absence of the second abscissa of hind wing vein Cu1, narrower hind femur (5.2 times as long as wide), and yellow subapical, lateral spots on metasomal tergites 2–5. Chablisea khuatdanglongi sp. n. is characterized by its face as high as wide, yellow with a median black stripe extending to a black transverse band at the base of the clypeus. One species, C. albifacialis (Kusigemati, 1984) is a new combination.     

Two Unrecorded Species of the Genus Enicospilus (Hymenoptera: Ichneumonidae: Ophioninae: Enicospilini) from Korea

ABSTRACT Two Enicospilus species, E. melanocarpus Cameron and E. pseudoconspersae (Sonan), are newly recorded in Korea. A revised key on the whole known Korean species including above two species are presented.
