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.
Project description:Prathapanius Viswajyothi & Clark, gen. nov., is described and illustrated. The genus is placed in the chrysomelid section Diabroticites Chapuis (subtribe Diabroticina Chapuis, tribe Luperini Chapuis, subfamily Galerucinae Latreille). It is monobasic, containing Prathapanius fortis Viswajyothi & Clark, sp. nov., from Ecuador. The new genus is briefly compared with Acalymma Barber, Isotes Weise, and Zischkaita Bechyné.
Project description:Chinese species of Chaetocnemasemicoerulea group are revised and three new species described as new: Chaetocnemasalixis sp. n., Chaetocnemayulongensis sp. n. and Chaetocnemadeqinensis sp. n..

Project description:The genus Atrachya Chevrolat is redefined based on study of the type species A. menetriesii (Faldermann, 1835). All Taiwanese species of Atrachya are transferred to three new genera: A. hirashimai Kimoto, 1976 and A. nitidissima (Chûjô, 1935) are transferred to Neochya gen. nov.; A. mediofasciata Kimoto, 1976 is transferred to Tsouchya gen. nov.; A. unifasciata Takizawa, 1978 is transferred to Chinochya gen. nov. Two species are described: N. chengi sp. nov. and N. tsoui sp. nov. Atrachya bicoloripennis (Chûjô, 1938) and A. saramao (Chûjô, 1962) are regarded as synonyms of N. nitidissima (Chûjô, 1935) comb. nov., and Monolepta tsoui Lee, 2009 is synonymized with T. mediofasciata (Kimoto, 1976) comb. nov. Monolepta sublata Gressitt & Kimoto, 1963 is redescribed and transferred to Chinochya gen. nov. Taiwanese records of Monolepta sublata are based on misidentifications and represent specimens of C. unifasciata. Variablity of adult color patterns is discussed.
Project description:In this study, five new species of the leaf-beetle genus Monolepta Chevrolat, 1836 (Coleoptera, Chrysomelidae, Galerucinae) are described from China: M.albipunctata sp. nov., M.alticola sp. nov., M.bivittata sp. nov., M.mengsongensis sp. nov., and M.rubripennis sp. nov.

Project description:The Chinese Chaetocnema picipes species-group is revised. It contains 5 species including 3 new species: C. cheni sp. n., C. constricta sp. n. and C. kingpinensis sp. n. The lectotype of C. fortecostata is designated. A key to all known species of this group from China and the illustrations of habitus and genitalia are provided. A distribution map of species is given.
Project description:Thirteen species of Pyrrhalta Joannis, 1865 with black elytron are reviewed. A key to species, photographs of aedeagus and habitus are provided. Pyrrhalta qianana sp. n. is described from Guizhou, China. Pyrrhalta martensi Medvedev & Sprecher-Uebersax, 1999 is newly recorded from China (Tibet).
