Description of a new species of the Charaeacoomani group (Coleoptera: Chrysomelidae: Galerucinae) from Vietnam with a key to species.

ABSTRACT:

Background

The genus Charaea Baly is distributed in the eastern Palaearctic, Himalayas, China and adjacent countries of the Oriental Region. Currently, 59 species of the genus Charaea have been recorded. The species of Charaea is characterised with a robust tubular aedeagus that terminates with a more or less distinct apical process with the Charaeacoomani group having an internal sac with long sharp lateral sclerites. Up to now, 13 species of this group have been described in the Oriental Region, four of which are found in Vietnam.

New information

Charaeadinhcuongi sp. nov. is described as a new species, based on specimens collected from Phu Quoc Island in southern Vietnam. Colour photographs of habitus and body details and DNA barcode sequences are presented. An identification key is provided for all Vietnamese species from the Charaeacoomani group.

Revision of the Theopea genus group (Coleoptera, Chrysomelidae, Galerucinae), part III: Descriptions of two new genera and nine new species.

Project description:This publication treats species within Theopea and closely allied genera that were not covered in the previous two revisions. Three species of Theopea Baly, 1864 are treated herein, with T. bicolor Kimoto, 1989 and T. mouhoti Baly, 1864 redescribed, and T. bicoloroides sp. nov. described. A new genus that we consider closely related to Theopea, Pseudotheopea gen. nov., is described. This new genus can be recognized with the presence of reticulate microsculpture on the vertex of the head and pronotum and presence of an apical spine on each metatibia. The following species are transferred to Pseudotheopea as new combinations: Theopea aeneipennis Gressitt & Kimoto, 1963, T. azurea Gressitt & Kimoto, 1963, T. clypealis Medvedev, 2015, T. nigrita Medvedev, 2007, T. smaragdina Gressitt & Kimoto, 1963, T. similis Kimoto, 1989, and T. subviridis Medvedev, 2012. Theopea subviridis Medvedev, 2012 is regarded as new synonym of Pseudotheopea similis (Kimoto, 1989). In addition, six new species of Pseudotheopea are described: P. boreri sp. nov. from India, P. gressitti sp. nov. from Philippines, P. hsingtzungi sp. nov. from Laos, P. kimotoi sp. nov. from Laos, Thailand, and Vietnam, P. leehsuehae sp. nov. from Laos, and P. sufangae sp. nov. from Taiwan. A second new genus regarded as closely related to Pseudotheopea, Borneotheopea gen. nov., can be recognized by possessing uniform antennae in both sexes and lacking an apical spine on each metatibia. Two new species of Borneotheopea are described from Borneo: B. jakli sp. nov. and B. kalimantanensis sp. nov.

Two new species of Hesperopenna Medvedev & Dang, 1981 (Coleoptera, Chrysomelidae, Galerucinae) from Singapore.

Project description:Two new species of Hesperopenna Medvedev & Dang, 1981 are described from Singapore: H.temaseksp. nov. and H.bakerisp. nov. The specimens of both new species were collected by Charles Fuller Baker and found in the unidentified Galerucinae material deposited in the National Museum of Natural History, Smithsonian Institution, Washington, DC. Hesperopennatemaseksp. nov. is diagnosed by the black extreme elytral suture in the basal third, antennae longer than the body, the structure of the penis, and the last abdominal ventrite with two deep U-shaped incisions in females. Hesperopennabakerisp. nov. is diagnosed by the black tibia and first two tarsomeres, and the structure of the penis.
