A review of the non-lyctine powder-post beetles of Yunnan (China) with a new genus and new species (Coleoptera: Bostrichidae)

Abstract

The powder post beetles (Coleoptera: Bostrichidae) (except Lyctinae) of Yunnan Province in Southwest China are reviewed for the first time. Keys to twenty-six genera and fifty-two species from the Yunnan region are provided. One new genus and seven new species are described: Dinoderus (Dinoderastes) hongheensis sp. nov., Dinoderus (Dinoderastes) nanxiheensis sp. nov., Gracilenta yingjiangensis gen. nov., sp. nov., Calonistes vittatus sp. nov., Calophagus colombiana sp. nov., Xylodrypta guochuanii sp. nov. and Xylodrypta zhenghei sp. nov.. Fourteen species are recorded in China for the first time. The bostrichid fauna of Yunnan is compared with those of the neighbouring bio-geographically related Southeast Asian and Himalayan regions. The fauna has a close affinity with that of tropical Southeast Asia and a much weaker relationship with the Palearctic region. The differences with the Himalayas may reflect the separate evolutionary and complex geological history of the two areas.

New records of powder-post beetles (Coleoptera, Bostrichidae) from China

“…China (Yunnan, Guangdong), India (Andaman Islands), Malaysia, Thailand, Vietnam, Myanmar ( Borowski and Węgrzynowicz 2007 , Zhang et al 2022 , Sittichaya 2023 ).…”

“…China (Yunnan, Guangdong, Sichuan, Hubei), India, Vietnam ( Liu and Beaver 2018 , Liu 2021 , Zhang et al 2022 ).…”

“…The family Bostrichidae is commonly recognised as a major pest group with an important economical value due to its negative impact on agroforestry ( Chu and Zhang 1997 , Chen 2011 ). Almost 90 species of the family have been recorded in China and several new species of powder-post beetles have been described in recent years ( Chu and Zhang 1997 , Hua 2002 , Liu et al 2006 , Borowski 2007 , Borowski and Węgrzynowicz 2007 , Liu 2010 , Chen 2011 , Liu 2021 , Zhang et al 2022 , Liu and Beaver 2023 ). However, detailed locality information on some of China's existing Bostrichidae species have not been specified ( Chu and Zhang 1997 , Borowski 2007 , Borowski and Węgrzynowicz 2007 , Chen 2011 , Liu 2021 ).…”

The Oriental genera of Xyloperthini (Coleoptera: Bostrichidae: Bostrichinae), with a new genus and species from Thailand, and a key to the genera

“…Lesne (1921 formally erected the tribe Xyloperthini Lesne, 1921 to include those genera with a lamelliform intercoxal process of the first abdominal ventrite. The tribe Xyloperthini is the most species-rich in the Bostrichidae, and currently includes 35 genera (Borowski & Węgrzynowicz 2007;Ivie 2010;Park et al 2015;Liu et al 2016;Liu & Beaver 2017;Liu 2021a;Zhang et al 2022).…”

“…The tribe has a worldwide distribution, but the individual genera are mostly confined to a single zoogeographical region or subregion (Morrone 2002;Borowski & Węgrzynowicz 2007;Beaver et al 2011;Holt et al 2013;Sittichaya et al 2013;Park et al 2015;Liu et al 2016Liu et al , 2021Liu & Beaver 2017;Borowski 2018;Liu 2021aLiu , 2021bZhang et al 2022), with the Oriental region having the most genera-rich fauna, and the African region the most species-rich fauna.…”
