The mirid genus Sulawesifulvius Gorczyca, Cherot & Stys (Hemiptera: Miridae: Cylapinae) is reported from China for the first time. One species, S. yinggelingensis sp. nov., is described from Yinggeling, Hainan Province, China. A key to the species of the genus is given. Photographs of the dorsal habitus and illustrations of the diagnostic characters of the new species are provided. All type specimens of the new species are deposited in the Institute of Entomology, Nankai University, Tianjin, China.

A new genus is established for two engimatic Old World ripidiine beetle species. Neopauroripidius Falin and Engel, new genus (Ripidiinae: Ripidiini), exhibits many unique features indicative of a relationship to the fossil genus Pauroripidius Kaupp and Nagel as well as a distinct extra notal sclerite not otherwise known among the Ripiphoridae. The arrangement of sclerites in the thoracic notum permits a reinterpretation of homologies. Brief comments on character transformations within Ripidiini and the affinities of the new genus are provided. The type species, Neopauroripidius darlingi Falin and Engel, new species, is described from the Philippines, while a second species, N. howdeni Falin and Engel, new species, is described from South Africa.

We provide information on the nesting behavior, natural enemies, seasonality, and host plants of Anthophora (Dasymegilla) waltoni Cockerell at mid-elevations in southern China (Yunnan Province). Bees nested singly inside loose mortar joints of building walls. Nests were shallow and consisted of an unlined, unbranched tunnel ending in a single cell. Surveys conducted every two or three days from February to April, 2013, showed that the studied population is univoltine, protandrous, and active in early spring. Females were more commonly observed than males, and no bees were observed flying by the end of April. Both sexes of A. waltoni were often collected on flowers of Vicia cracca Linnaeus (Fabaceae).

The pupal case of the Nearctic robber fly, Efferia snowi (Hine, 1919), is described, illustrated, and compared with the pupal cases of five other Nearctic species. A key is provided to the known pupal cases of Nearctic Efferia species.

Considered is the taxonomy of 5 previously described genera (Solervicensia Barr, Boschella Barr, Pyticara Spinola, Pelonides Kuwert, Parapelonides Barr) and two new genera (Agnatis Opitz, Undecima Opitz). Two new species are described: Agnatis variabilis Opitz, new species and Undecima arta Opitz, new species. Seventeen characters were evaluated phylogenetically and analyzed with WINCLADA, in combination with NONA. Three trees were produced. It is hypothesized that the ancestral stock that generated the genera under study originated in the clerofaunas of South America, probably within the environs of the Altiplano Complex. It is further hypothesized that there were two independent invasions into the terrain of Middle America. These northern excursions would have taken place after the early closure of the Panamanian portal, some 25 million years ago. Moreover, the ancestors of the Middle American stocks would have also traversed the Nicaraguan Depression. Included in this work are descriptions of generic taxa, descriptions of two new species, key to genera, 102 line drawings, 16 Scanning Electron Micrographs, 3 phylogenetic trees, and 15 color habitus illustrations.

Este trabajo incluye la taxonomía de cinco géneros previamente descritos (Solervicensia Barr, Boschella Barr, Pyticara Spinola, Pelonides Kuwert, Parapelonides Barr) y dos géneros nuevos (Agnatis Opitz y Undecima Opitz). Dos especies nuevas son descritas: Agnatis variabilis Opitz, especie nueva y Undecima arta Opitz, especie nueva. Diecisiete caracteres fueron evaluados y analizados con WINCLADA, en combinación con NONA. Tres arboles fueron producidos. La hipótesis resultante considera que los ancestros de los géneros estudiados son de origen suramericanos, probablemente de los alrededores del Complejo del Altiplano. Se plantea la hipótesis de dos invasiones independientes hacia Mesoamérica, tomando lugar justo después del cierre del Portal de Panamá, hace 25 millones de años. También estos ancestros de los géneros Mesoamericanos también atravesaron la Depresión de Nicaragua. En este trabajo se redescriben los géneros existentes y nuevos, así como las dos especies nuevas. Se incluye una clave de los géneros, 102 dibujos negro y blanco, 16 fotos con microscopio electrónico, 3 árboles filogenéticos y 15 ilustraciones a color de habitus.

A new family, Cretostylopidae Kathirithamby and Engel, is erected to accommodate the mid-Cretaceous species Cretostylops engeli Grimaldi and Kathirithamby. Based on this as well as various other recent works pertaining to the higher classification of Strepsiptera, a revised key is provide to the living and fossil families.

An unusual deformity is reported for a female of the augochlorine bee Caenaugochlora (Caenaugochlora) inermis (Vachal). The individual has malformations of the vertex which resulted in two additional lateral ocelli near the compound eyes and apparently a forward contraction of the vertex shifting the ocellar triangle further into the upper frons. A brief account and figure of the specimen is provided.
