Two New Species of Amphidromus (Mollusca: Gastropoda: Camaenidae) from Indonesia and Vietnam

Two new species of the land snails in the genus Amphidromus Albers, 1850 from Indonesia, and Vietnam are described: Amphidromus gisellelieae n. sp. from Indonesia, Amphidromus phamvutuanhae n. sp. They are compared to the closest congeners in this genus.

Introducing a new genus of Marginellidae from Africa: Africosta new genus (Gastropoda: Marginellidae) along with the description of two new species

A small group Marginellidae species were moved between genera several times by different authors, described as Marginella, sometimes called Glabella, classified under Dentimargo, and also reclassified as being Eratoidea species. This group of very small Marginellidae has their own unique shell characteristics within the family, and are described here within a new genus: Africosta. Four known species are discussed along with the description of two new species from KwaZulu-Natal, South Africa within the new genus.

Two new species of Acanthocinini (Coleoptera, Cerambycidae, Lamiinae) from the Neotropical Region

Two new species of Acanthocinini are described from the Neotropical region: Leptostylus skillmani, from Guatemala; and Anisopodus morrisi, from French Guiana. Additionally, the holotype of Leptostylus lilliputanus Thomson, 1865 is illustrated for the first time.

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.

Cryptic Species Diversity and Phylogenetic Relationship in the Rust Genus Chrysomyxa from China

Chrysomyxa rusts are fungal pathogens widely distributed in the Northern hemisphere, causing spruce needle and cone rust diseases, and they are responsible for significant economic losses in China. Taxonomic delimitation and precise species identification are difficult within this genus because some characters often overlap in several species. Adequate species delimitation, enhanced by the use of DNA-based methodologies, will help to establish well-supported species boundaries and enable the identification of cryptic species. Here, we explore the cryptic species diversity in the rust genus Chrysomyxa from China. Species delimitation analyses are conducted using a distance-based method (ABGD) and three tree-based methods (GMYC, bPTP, and mPTP) based on combined LSU and ITS sequences of over 60 specimens. Although there is some incongruence among species delimitation methods, two new species and three putative cryptic species are identified. The key to 20 Chrysomyxa species distributed in China is presented. These results suggest that a significant level of undiscovered cryptic diversity is likely to be found in Chrysomyxa from China. Future studies should consider multiple analytical methods when dealing with multi-locus datasets.

Fifth contribution to the study of the Lithosiini of Gabon: two genera new for Gabon, with a description of two new species (Lepidoptera: Erebidae: Arctiinae)

Pusiola celida Bethune-Baker, 1911 and Novilema fluminale Durante & Panzera, 2001b are recorded for the first time in Gabon; the synonymy of the subspecies P. celida celida Bethune-Baker, 1911 and P. unipunctana maior Durante & Panzera, 2002a is revised; two species are described as new: Pusiola unicolor Durante new species and Novilema bifurcum Durante new species. The exclusion of Archilema triangulare Durante & Panzera, 2001b from the genus Novilema Durante & Panzera, 2001b is discussed together with criteria for assigning four species of the genus Archilema Birket-Smith, 1965 to the subgenera identified by Birket-Smith (1965). These species are as follows: Archilema (Archilema) lucens Durante & Panzera, 2002c; Archilema (Archilema) subalba Durante & Panzera, 2001b; Archilema (Palilema) quadrilobata Durante & Panzera, 2001b; Archilema (Palilema) triangularis Durante & Panzera, 2001b.

The First Report of the Genera Abaria and Drepanocentron (Trichoptera: Xiphocentronidae) from China, with Descriptions of Two New Species

The genera Abaria Mosely 1948 and Drepanocentron Schmid 1982 are recorded in China for the first time. In this study, two new species, Abaria herringbona sp. nov., from Guang-xi, and Drepanocentron fuxiensis sp. nov., from An-hui, are described and illustrated. Male genitalia of these two new species is distinguishable from those of other Abaria and Drepanocentron species. In addition, Melanotrichia attia Malicky & Chantaramongkol 1992 is a new record for the Chinese caddisfly fauna.

Two new species of the spider genus Sinamma Lin & Li, 2014 (Araneae, Tetrablemmidae) from Guangdong Province, China

Two new species of the genus Sinamma Lin & Li, 2014, Sinamma quadrata Tong & Li, sp. nov. (male, female) and Sinamma yingae Tong & Li, sp. nov. (male, female) are described from Guangdong, China. The geographic distribution of the genus is updated and a key to all known species 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). A key to the known species is included, with photographs of the dorsal habitus and female genital plates provided.
