Review of Proxima DeLong & Freytag (Hemiptera: Cicadellidae: Gyponini) with description of two new species from Brazil and identification key to species

The previously monotypic genus Proxima DeLong & Freytag, 1975 is reviewed and new diagnostic characters are added. The type-species Proxima ocellata DeLong & Freytag, 1975 described from the State of Espírito Santo, Brazil, is redescribed and newly recorded from the State of Minas Gerais. Also, two new species are described and illustrated: Proxima nigromaculata sp. nov. from the states of Espírito Santo, Maranhão, Minas Gerais, Rio de Janeiro and Rio Grande do Sul and Proxima meloi sp. nov. from the states of Bahia and Minas Gerais. An identification key to the species of the genus is provided.

A new species of the waspfish genus Ocosia (Teleostei: Tetrarogidae) from the Coral Sea, with a key to species in the genus

The new waspfish Ocosia dorsomaculata n. sp. (Tetrarogidae) is described, based on specimens from Australia (5) and New Caledonia (51). Although O. dorsomaculata and Ocosia apia Poss & Eschmeyer 1975 both share modally XVI, 8 dorsal-fin rays with a long second dorsal-fin spine, and presence of supraocular, lateral lacrimal, and suborbital spines, the former has modally 13 pectoral-fin rays (vs. usually 12 in the latter), a lower modal count of total gill rakers (10 vs. 16–18), greater upper-jaw length, greater third to sixth dorsal-fin spine lengths, the third dorsal-fin spine slightly shorter than the second dorsal-fin spine (vs. third spine markedly shorter than second spine), 1 or 2 prominent pale brown to dark brown blotches on the membrane between the fifth to eighth or sixth to ninth dorsal-fin spines (vs. 1 blotch on the membrane around the third dorsal-fin spine and 1 blotch on the membrane between the sixth to eighth dorsal-fin spines), and body with 11–15 longitudinal pale brown to dark brown bars along lateral line (vs. irregular brown specks). A key to the species of Ocosia is given.

The genus Cacodaemon (Coleoptera, Endomychidae) of Vietnam

The species of the genus Cacodaemon of Vietnam are revised. A new species, Cacodaemon vietnamensissp. nov., is described and C. laotinus laotinus (Arrow, 1920) is newly recorded from Vietnam. A previously known species, C. proavus Strohecker, 1964 is redescribed based on an additional female specimen and a key to species of the genus Cacodaemon in Vietnam is provided.

Description of two new micropterous species of Monasavuhygia Brailovsky, 1996 from the Fiji and Solomon Islands and a key to species (Heteroptera: Coreidae: Colpurini)

The genus Monasavuhygia Brailovsky, 1996 is revised. Two new species collected in the Fiji Islands and Solomon Islands, respectively, are described in the Tribe Colpurini (Heteroptera: Coreidae).

Description of two new species of the genus Baburia Koçak, 1981 (Lepidoptera: Tortricidae: Olethreutinae) from India

The genus Baburia Koçak, 1981 of the tribe Olethreutini is newly recorded from India. Two new species B. tinsukiaensis Shashank, n. sp., and B. chettalliensis Shashank and Santhosh, n. sp. are described. This increases the number of species of Baburia to five. Photographic illustrations after the description of two new taxa, checklist and key to species of this genus are provided.

Pseudocetherinae (Hemiptera: Reduviidae) revisited: phylogeny and taxonomy of the lobe-headed bugs

The concept of the previously monogeneric subfamily Pseudocetherinae (Hemiptera: Heteroptera: Reduviidae) is revised and expanded. We here transfer Gerbelius Distant, 1903, Kayanocoris Miller, 1954, Microvarus Jeannel, 1917, Paragerbelius Miller, 1958, and Voconia Stål, 1866 from Reduviinae to Pseudocetherinae and treat Kayanocoris, Microvarus, Paragerbelius, and Pseudocethera Villiers, 1963 as junior synonyms of Voconia, resulting in new combinations for Voconia conradti (Jeannel, 1917) comb. nov., V. ifana (Villiers, 1963) comb. nov., V. monodi (Villiers, 1963) comb. nov., V. motoensis (Schouteden, 1929) comb. nov., V. ornata (Distant, 1903) comb. nov., V. schoutedeni (Villiers, 1964) comb. nov., V. typica (Miller, 1958) comb. nov., and V. wegneri (Miller, 1954) comb. nov. We also describe 23 new species of Voconia: V. bakeri sp. nov., V. bracata sp. nov., V. brachycephala sp. nov., V. chrysoptera sp. nov., V. coronata sp. nov., V. decorata sp. nov., V. dolichocephala sp. nov., V. fasciata sp. nov., V. grandioculata sp. nov., V. hemera sp. nov., V. isosceles sp. nov., V. laosensis sp. nov., V. lasiosoma sp. nov., V. lirophleps sp. nov., V. loki sp. nov., V. mexicana sp. nov., V. minima sp. nov., V. nyx sp. nov., V. smithae sp. nov., V. tridens sp. nov., V. trinidadensis sp. nov., V. tuberculata sp. nov., and V. vittata sp. nov. Lectotypes are designated for Gerbelius confluens Distant, 1903, G. typicus Distant, 1903, V. conradti comb. nov., V. ornata comb. nov., and V. pallidipes Stål, 1866. A revised diagnosis and description of Pseudocetherinae are provided along with photographs of the species and of the male genitalia of 13 pseudocetherine and five closely related reduviine species. An identification key to the two genera of Pseudocetherinae as well as a key to species of Voconia are presented. A phylogenetic hypothesis is proposed for the relationships of Pseudocetherinae using parsimony analyses of 77 morphological characters.

Revision of Malagasy species of the genus Merma Weise (Coccinellidae: Epilachnini)

Malagasy Epilachnini are one of the least studied groups of the herbivorous ladybird beetles. Most of the species were described in the 19th and 20th centuries and their position within the modern classification has never been examined. Here we provide results of detailed study of two species Epilachna hovana Sicard, 1907 and Peralda quadriguttata, Sicard, 1909 which are proposed to be transferred to the genus Merma Weise (comb. nov.). Detailed morphological analysis, photographs of male and female genitalia and a key to species are also provided.

Three New Species and One New Record of Hesperoschema (Coleoptera: Staphylinidae: Staphylininae) from China

Three new species: Hesperoschema xuwangi sp. nov. from China (Sichuan), H. bii sp. nov. from China (Xizang), and H. sinicum sp. nov. from China (Guangxi) are described. Hesperoschema malaisei Scheerpeltz, 1965 is new to China (Yunnan), with the male discovered for the first time. The female of H. opacum Schillhammer, 2009 is discovered for the first time. Habitus and diagnostic characteristics of the species treated in this paper were photographed, and a key to species of Hesperoschema Scheerpeltz, 1965 is updated.

The ontogenetic changes in the idiosoma and leg chaetotaxy on adults (female and male) and immature stages of this new species are presented. A key to species of Colopalpus is also provided.

Two new species of Cymodusa Holmgren (Hymenoptera, Ichneumonidae) with a key to species known from China and Oriental region
