Fossil Specimen

A new genus and species, Mirimordella gracilicruralis gen. et sp. nov., in the subfamily Praemordellinae of Mordellidae, is described and illustrated based on a nearly complete fossil specimen. It is from the Yixian Formation of western Liaoning Province, NE China. The diagnosis of the subfamily Praemordellinae is emended based on this new species. Characters such as simple and linear maxillary palpi, simple claws, simple penultimate segments of fore and middle tarsi, small hind coxal plates, slender hind femora, only apical ridges on hind tibiae and tarsi, and no elongated last tergum suggest that Praemordellinae might be the precursor of modern mordellids. The resemblance between the new species and the Late Jurassic Praemordella martynovi indicates close relationships between them and with the tribe Stenaliini in the subfamily Mordellinae. The position of epicoxa and slender hind femur suggest that the new species may be more primitive than Praemordella martynovi and may indicate the age of the Yixian Formation no later than Late Jurassic.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.

A new genus and species of Philopotamidae (Philopotaminae),Aymaradellaboliviana, is described from the Bolivian Andes of South America. The new genus differs from other Philopotaminae by the loss of 2A vein in the hind wing and, in the male genitalia, the synscleritous tergum and sternum of segment VIII, and the elongate sclerotized dorsal processes of segment VIII. The first record ofHydrobiosella(Philopotaminae) in the New World is also provided with a new species from the Andes of Ecuador,Hydrobiosellaandina. In addition, a new species of the Neotropical genusChimarrhodella(Chimarrinae),Chimarrhodellachoco, is described from the Choco-Andean region of Ecuador, andChimarrhodellaperuviana(Ross) is recorded from Ecuador for the first time. Lastly,Wormaldiaimbrialis(Philopotaminae), new species, is described, also from the Ecuadorian Choco.

A New Species

New taxa of the family Ropalomeridae from Costa Rica are described, and additional records of ropalomerid flies fromMexico and Central America are provided. The new genus and species Acrocephalomyia zumbadoi can be easily distin-guished from all other ropalomerid genera by the following combination of characters: angular forward projection of head,absence of ocelli, flat face, bare arista, long scutum, and scutellum triangular-shaped and dorsally flattened with only onepair of apical bristles with bases approximated. The new species Ropalomera aterrima can be recognized from congenersby remarkable differences of the head, the shape of the scutellum, the absence of scutal vittae, fumose wings, and by theblack coloration of the body, ocellar bristles large, one postpronotal bristle, scutum without pollinose vittae and flat scutellum. Lenkokroeberia chryserea Prado and Kroeberia fuliginosa Lindner are newly confirmed for Costa Rica.

A new genus and two new species of fossil Elateridae are described and illustrated: Paralithomerus gen. nov., P. exquisitus sp. nov, and P. parallelus sp. nov. Both species were collected from the Late Jurassic-Early Cretaceous Yixian Formation of western Liaoning, China. Fossil elaterids expressing a sutured mesoventrite have been otherwise discovered only from the Upper Jurassic strata of Karatau.

A new genus and a new species, Haplodendron buzwilsoni, from the southeastern Australian mid bathyal are described. This is the first record of the family in the Southern Hemisphere IndoPacific. Diagnostic characters of the new genus are compared with those of other genera in the family. The possible significance of the joint possession, between the new genus and Dendrotion (Dendrotiidae), of a stalk carrying the antennulae and antennae is discussed. New observations on male reproductive structures are made.

A new species of the family Prophalangopsidae, Ashanga borealis sp.n., is described from the Lower Cretaceous Yixian Fomation (Liaoning Province, P.R. China). The male forewing of the new species is similar to that of the Middle/Upper Jurassic species Ashanga clara Zherikhin 1985, but differs from it in possessing a forewing arched anterior margin, RS branching more basally, and MP + CuA1 with more branches. The fossil record of Chifengiinae is reviewed.

A new genus with a new species (Shoushida regilla gen. et sp. nov.) of pelecinid wasps is described and illustrated. The fossil has been collected from the Upper Jurassic to Lower Cretaceous of Yixian Formation at Huangbanjigou Village, Liaoning Province, China. The new species has vein Rs forking to two branches: Rs 1 straight and reaching wing margin much before apex and Rs 2 long, forming an “X” pattern together with 2r-rs. This finding represents the earliest fossil record of subfamily Pelecininae in the world up to date. Sexual dimorphism in Pelecinidae is briefly discussed.
