Abstract Describes and illustrates all the forms of the pelecypod Liogryphaea known from the lower Jurassic of the eastern Paris basin, France, including two new species and four new varieties. The phylogenetic relationships of the group are discussed and illustrated in a table.

A little known tachinid genus, Metadrinomyia Shima, is revised based on four East Asian species including two new to science: M. flavifrons sp. nov. and M. xanthokolos sp. nov. The majority of the specimens used in this study were collected from low vegetation in the foothills of mountains in South Korea. The new species can be clearly distinguished from their congeners by their pruinosity, chaetotaxy and genitalic structures. A key, descriptions, photographs, and illustrations of the male genitalic structures are provided and the phylogenetic relationships among the species are investigated.

AbstractTwo new species belonging to the genus Anastrepha, A. mayasp. nov. and A. relictasp. nov., are described. These species are noteworthy because they are closely related to A. tripunctata van der Wulp, an endemic Mexican species currently classified in the cryptostrepha species group, which may be the basal lineage of the genus. These new species come from several tropical Mexican localities and share several taxonomic characters found only in A. tripunctata. The eight known species of the cryptostrepha group are keyed, and a discussion of the phylogenetic relationships between this group and other species groups of Anastrepha is presented.

AbstractThe new genus Deleyia gen. n., including two new species, D. poinari gen. n., sp. n. and D. aspiculata gen. n., sp. n., is described from terrestrial material (rotting wood and moss) in Ukraine. The new genus is inter alia characterised by the outer cuticular layer being defoliated along most of the body, except for labial region and tail posterior to phasmid, forming a cuticular sheath around the body and a vulval cuticular sac in females, and reduced stoma and basal bulb. Deleyia poinari gen. n., sp. n. is separated from D. aspiculata gen. n., sp. n. by a shorter body (L = 600-831 vs 756-945 μm), a shorter PUS (7-18 vs 44-69 μm), longer tail in both females and males (40-50 vs 32-38 μm and 37-48 vs 35 μm, respectively), and presence vs absence of spicules and gubernaculum. The phylogenetic position of Deleyia gen. n. and its relationships to the genera Daubaylia and Myolaimus are discussed.

AbstractPseudocomotis, new genus, is described to accommodate Orthotaenia scardiana Dognin, Cnephasia citroleuca Meyrick (both formerly in Orthocomotis Dognin), Eulia agatharcha Meyrick, and two new species, serendipita and albolineana. The presence of a broad saccus - vincu-1um complex, hami, a hairpencil from abdominal segment VIII in the male, and the wide basal separation of hindwing veins M2 and M3, indicate that Pseudocomotis belongs in the Chlidanotini (Chlidanotinae). The single female associated with the new genus lacks the abdomen, prohibiting genitalic diagnosis and comparison with closely related genera. Phylogenetic relationships among the Polyorthini, Hilarographini, and Chlidanotini are discussed.
