One new species of the subgenus Hexatoma (Eriocera) Macquart (Diptera,Limoniidae) from China with a key to Chinese species

A key to all of 78 known species from China in the subgenus is provided, which was solely based on literatures. The new species is similar to Hexatoma (Eriocera) cleopatra Alexander, 1933, but distinguishes from the latter by the prescutum entirely black with two ill-defined gray stripes, by the legs with fore and middle femora brown in basal half, black in apical half, with hind femora brown in basal one-fourth, and by the wings with cells c and sc more yellowish brown than the ground color.     

A new species of the genus Anteon Jurine (Hymenoptera,Dryinidae) from Laos

A new species of Anteon Jurine, 1807 is described from Laos, Houaphanh Province: Anteon holzschuhi sp. n. Morphologically the new species is similar to Anteon semipolitum Olmi, 2008, but it is distinguished by the sculpture of the face partly reticulate rugose and partly with deep punctures similar to areolae; in Anteon semipolitum the face is completely punctate and unsculptured among punctures. In addition, in the new species the distance from the outer edge of a lateral ocellus to the compound eye (OOL) is about 3.3 times as long as the distance between the inner edges of a lateral ocellus and the median ocellus (OL); in Anteon semipolitum OOL is less than twice as long as OL. Published identification keys to the Oriental species of Anteon are modified to include the new species.

A new species group in Megaselia,the lucifrons group,with description of a new species (Diptera,Phoridae)

With 1,400 described species, Megaselia is one of the most species-rich genera in the animal kingdom, and at the same time one of the least studied. An important obstacle to taxonomic progress is the lack of knowledge concerning the phylogenetic structure within the genus. Classification of Megaselia at the level of subgenus is incomplete although Schmitz addressed several groups of species in a series of monographs published from 1956 to 1981. Another problem is the lack of molecular phylogenetic analyses to support morphology-based conclusions. As a contribution towards addressing these problems, we here circumscribe a previously unrecognized monophyletic lineage of Megaselia consisting of species similar to Megaselia lucifrons. We base this taxonomic decision on morphological study of an extensive phorid material from Sweden, complemented by molecular analyses of select exemplars using two markers (COI and 28S). We name the clade the lucifrons species group, and show that it contains three distinct species. Our results also demonstrate that Megaselia subnitida Lundbeck, 1920, previously treated as a synonym of Megaselia lucifrons Schmitz, 1918, is a separate species, and we remove it from synonymy. The third species in the group was previously unknown; we describe it here as Megaselia albalucifrons sp. n.     

A new species of the genus Anteon Jurine (Hymenoptera,Dryinidae) from Thailand

A new species of Anteon Jurine, 1807 is described from Thailand, Nan Province: Anteon huettingeri sp. n.

Published identification keys to the Oriental species of Anteon are modified to include the new species.
