A new genus, Diacanthomyia gen. nov. assigned to the subtribe Thyreophorina of the family Piophilidae is described based on a new species, Diacanthomyia okidoi sp. Nov. recently found in Honshu and Kyushu, Japan. The new genus is somewhat similar to the European Centrophlebomyia of the subtribe. However, the new genus is distinguished from the known genera of the subtribe by the following combination of characters: body extensively pollinose or pruinose, 2 pairs of strong reclinate fronto-orbital bristles, 1-2 strong subvibrissal bristles in addition to 2 strong vibrissae, prosternum setose, 1 presutural dorsocentral, 1 strong anterior postsutural intra-alar, scutellum with 2 pairs of scutellar bristles without additional setulae, extensively microtrichose wing membrane, a dark round spot at r-m crossvein and a dark stripe covering m-m crossvein, and vein CuA+CuP abruptly terminated distant from wing margin. The type species inhabits evergreen broadleaved and deciduous broadleaved forests and adults appear during the cold season from December to March. Adults are attracted to decaying carcasses of Japanese deer and wild boar and traps baited with decaying pork spareribs and chicken meat with bones. The larvae of this species feed on decaying meat and marrow of deer, take less than 2 months to grow to mature larvae, and enter into diapause in the soil until autumn.

The type series of Empis (Planempis) mandarina Frey, 1953, the type species of Planempis Frey, from Fukien (Fujian), China and Kambaiti, Myanmar is revised and found to include four species. The lectotype is designated for a Fukien male specimen. Two other species, E. (Planempis) lindebergi sp. nov. and E. (Planempis) janssoni sp. nov. are described based on a male syntype, and a male and three female syntypes from Kambaiti, respectively. A species represented by females from Fukien is not conspecific with any of these species and remains unnamed. Copyright © 2012 Magnolia Press.

Six shore-dwelling species of the rectus group of the genus Conchopus Takagi are recognized from the Hawaiian and Wake Islands, including five new species. Conchopus is restricted to this species group herein. Contrary to some earlier records, C. acrosticalis (Parent, 1937) occurs only on four of the Hawaiian Islands (Hawai'i, Maui, Lāna'i, and Moloka'i). The new species are distributed as follows: C. ciliatus sp. nov. (Hawai'i, Maui, O'ahu and Lisianski Is.); C. crassinervis sp. nov. (Kaua'i); C. minutus sp. nov. (Hawai'i, Maui, Lāna'i, O'ahu, and French Frigate Shoals); C. menehune sp. nov. (Kaua'i and Nihoa Is.); and C. pacificus sp. nov. (Hawai'i, O'ahu, Kaua'i, and Wake Is). A key to the males of all known species of the rectus group is provided. Copyright © 2010 Magnolia Press.

Two new species of the genus Proutia are described from Japan based on both sexes. Proutia maculatella sp. nov. is distinctive in having maculated forewing upperside. Proutia nigra, sp. nov. has unicolorous blackish brown forewing upperside and similar to the European species, P. betulina, but differs from the latter in the longer processes of the male valvae and shorter female antennae.
