This comparative cladistics study utilized parsimony analyses, with 57 terminal taxa (including five outgroups) and 18 characters from the ileum of most genera of passalid beetles (Coleoptera: Passalidae), which resulted in a single tree. Based on the results and the topology of the cladogram, the following classification was adopted: (Aulacocyclinae (Solenocyclinae (Proculinae (Passalinae, Macrolininae)))). Three subfamilies (Solenocyclinae, Proculinae, and Macrolininae) are here elevated from the tribal level to the subfamily level. The subfamily Passalinae is redefined and no longer containsany tribes. The family-group name Leptaulacinae is placed in synonym with Solenocyclinae and the family-group name Ceracupedini is placed in synonymy with Aulacocyclinae.

Images of the following morphological structures of all larval instars are provided: pseudocephalon, antenna, maxillary palpus, facial mask, cirri, mouth hooks, ambulatory lobes, anterior and posterior spiracles. Illustrations of the cephalopharyngeal skeleton for all three instars in lateral, ventral and dorsal views are provided. All instarsare clearly separable by morphological features. The first instar has unique modification of the facial mask and structure of the cephalopharyngeal skeleton. Second and third instars are similar in overall form and differ in details in structure of themouthooks and anterior spiracles, and by the number of pharyngeal ridges.
查看更多>>摘要：Comments are presented on four East-Asian species of the genus Chilocoris Mayr, of which three are known but have been hardly mentioned-namely C. alienus Horvath, C. birmanus Lis and C. nitidulus Lis. One new species is described here as C. monticola n. sp. New distribution records are provided: C. alienus is new to China (Liaoning), as well as newly representing the genus in northern China; C. birmanus is new to Taiwan; and C. nitidulus is new to Vietnam and Thailand. Until recently, C. monticola n. sp. found in Japan has been misidentified as C. nitidus Mayr, and earlier records of the latter from Japan are really this new species. Male genital structures are described and illustrated for all four species, and additionally female genital structures are also described for C. birmanus and C. monticola. These East-Asian species are significantly similar to each other in important morphological structures such as the pronotal punctuation, extension of evaporatorium, and the male and female genital organs, yet they can be distinguished from many other congeners by these same structures. It seems plausible, therefore, to group these four species in a species-group named "nitidus-group" because of the species' definite association with C. nitidus. This species-group possibly consists at least ten East-Asian and one North American species and exhibits a relictual, trans-Beringian disjunction, suggesting an association of this group with the Tertiary circum-boreal flora. Its distributional pattern may further differentiate the species-group from other congeners.
查看更多>>摘要：From Hainan Province, southern China, a new genus of Carventinae: Caiaptera n. gen with the species C. picea n. sp. and a new genus of Mezirinae: Hainanmezira n. gen with the species H. latiscutellata n. sp. as well as Notoplocaptera hainanensis n. sp., are described and illustrated. Additional records are given, and a list of species recorded to date from this province is presented.
查看更多>>摘要：The four species included by Wood and Bright (1992) in the Palaeotropical scolytine genus Phloeosinopsioides Schedl are reviewed. The following new synonymy is proposed: Phloeosinopsioides formosanus (Schedl) (=Phloeosinopsis triseriata Schedl). A diagnosis of the genus and a key to the three species now included in the genus are provided. The taxonomy, distribution and biology of the species are briefly reviewed and some new records included.
查看更多>>摘要：Two new species of water scavenger beetles, Oocyclus fikaceki Short & Jia sp. n. and O. dinghu Short & Jia sp. n. are described from Guangdong, Fujian, and Jiangxi Provinces in southeastern China. A revised key to the species of the genus in Indochinaand surrounding mainland regions is presented.
