RESUMEN

The genera Echinovelleda Breuning, 1936 and Propedicellus Huang, Huang & Liu, 2020 are revised. The latterisconsideredto be ajunior synonym of theformer based on a comprehensive morphological investigation, especially on the characteristics of male endophallus. Two new species are described from China, viz. Echinovelleda mumuae Bi & Mu sp. nov. from Yunnan and Guangxi, and E. protochinensis Bi & Lin sp. nov. from Yunnan and Sichuan. New records are reported for previously described taxa including one new country record of a morphologically similar genus, Hechinoschema Thomson, 1857 from China. Illustrations of habitus, endophallic structure, major diagnostic features for all studied taxa, as well as a distributional map are provided.

RESUMEN

The genus Meges Pascoe, 1866 stat. res. is resurrected from synonyms of Monochamus Dejean, 1821 and is made a senior synonym of Magninia Clermont, 1932 syn. nov. Meges currently contains two species, i.e. Meges gravidus (Pascoe, 1858) and Meges tonkineus (Clermont, 1932) comb. nov. The male of the latter species is described for the first time. A related genus Pseudomeges Breuning, 1944 is investigated for comparison and Pseudomeges aureus Bi, Chen Lin sp. nov. (, Jn bn wi m tin ni) is described from Yunnan, China. New localities are reported. Illustrations of habitus, endophallic structures and major diagnostic features for all involved taxa are provided.

RESUMEN

This work presents a review of species of the Asian genus Sinocymbachus Strohecker & Chûjô, 1970. Four new species are described from China: S. fanjingshanensis Chang & Bi, sp. nov., S. longipennis Chang & Bi, sp. nov., S. sinicus Chang & Bi, sp. nov., and S. wangyinjiei Chang & Bi, sp. nov. Cymbachus koreanus Chûjô & Lee, 1993 is transferred to Sinocymbachus as S. koreanus (Chûjô & Lee) comb. nov. Sinocymbachus bimaculatus (Pic, 1927) is reported for the first time from China. The male of S. parvimaculatus (Mader, 1938) is discovered and described for the first time. Illustration, diagnosis and distribution are provided for each species. Prior to the present study, Sinocymbachus included ten species. An updated key to the species of Sinocymbachus is given.

RESUMEN

Ithocritus ruber (Hope, 1839), the type species of the genus Ithocritus Lacordaire, 1872 is reinvestigated, and a partially sympatric species, Ithocritus similis Bi Lin, sp. nov. (, Xiang sì duǎn bǐng tian niú), is described. The genus Falsimalmus Breuning, 1956 is newly recorded from China, based on the discovery of Falsimalmus niger Breuning, 1956 from Yunnan. New localities, illustrations of habitus, endophallic structure and major diagnostic features for all involved taxa are provided.

RESUMEN

This paper presents a review of the genus Brachytrycherus Arrow from mainland China. Three new species are described and illustrated: B. bipunctatus Chang & Bi, sp. nov., B. denticulatus Chang & Bi, sp. nov., and B. humeralis Chang & Bi, sp. nov. The diagnosis, distribution, type locality, biology, and ecology are provided for each species. A key to the species of Brachytrycherus known in China is updated.

RESUMEN

The new subfamily Sinopyrophorinae within Elateridae is proposed to accommodate a bioluminescent species, Sinopyrophorusschimmeli Bi & Li, gen. et sp. nov., recently discovered in Yunnan, China. This lineage is morphologically distinguished from other click-beetle subfamilies by the strongly protruding frontoclypeal region, which is longitudinally carinate medially, the pretarsal claws without basal setae, the hind wing venation with a well-defined wedge cell, the abdomen with seven (male) or six (female) ventrites, the large luminous organ on the abdominal sternite II, and the male genitalia with median lobe much shorter than parameres, and parameres arcuate, with the inner margin near its apical third dentate. Molecular phylogeny based on the combined 14 mitochondrial and two nuclear genes supports the placement of this taxon far from other luminescent click-beetle groups, which provides additional evidence for the multiple origin of bioluminescence in Elateridae. Illustrations of habitus and main diagnostic features of S.schimmeli Bi & Li, gen. et sp. nov. are provided, as well as the brief description of its luminescent behavior.

RESUMEN

A revision of the genus Eutetrapha Bates, 1884 is presented. Four new species are described from China: E. parastigmosa Lin & Yang, sp. nov. from Hubei, Chongqing and Shaanxi; E. tianmushana Lin & Bi, sp. nov. from Zhejiang; E. shaanxiana Lin & Yang, sp. nov. from Shaanxi, Hubei, Gansu; and E. gui Lin & Yang, sp. nov. from Hainan. Eutetrapha virides Pu & Jin, 1991 is transferred to the genus Paraglenea, and Glenea ocelota Bates, 1873 is transferred from Eutetrapha to Saperda (Lopezcolonia). Eutetrapha laosensis is newly recorded from India and Myanmar, while Eutetrapha flavoguttata Pu & Jin, 1991 is newly recorded from Myanmar. India and Myanmar represent new country records for Eutetrapha. Twenty-one taxa are recognized in the genus Eutetrapha, and a key to the described species of the genus is presented.

RESUMEN

The genus Pseudoechthistatus Pic, 1917 is redefined and revised. Five species of the genus are described as new, Pseudoechthistatus sinicus sp. n. and Pseudoechthistatus chiangshunani sp. n. from central Yunnan, China, Pseudoechthistatus pufujiae sp. n. from western Yunnan, China, and Pseudoechthistatus holzschuhi sp. n. and Pseudoechthistatus glabripennis sp. n. from southern Yunnan and northern Vietnam. Pseudoechthistatus birmanicus Breuning, 1942 is excluded from the fauna of China. Three poorly known species, Pseudoechthistatus obliquefasciatus Pic, 1917, Pseudoechthistatus granulatus Breuning, 1942, and Pseudoechthistatus acutipennis Chiang, 1981 are redescribed, and the type localities of the former two species are discussed. Endophallic structure of seven species in inflated and everted condition are studied and compared with their relatives. Illustrations of habitus and major diagnostic features of all species are provided. Some biological notes are reported. An identification key as well as a distributional map are presented.

RESUMEN

Two new species of Brachytrycherus from China, Brachytrycherus conaensis sp. n. and Brachytrycherus curviantennae sp. n. are described and illustrated. Brachytrycherus conaensis sp. n. is the first species of the Handsome Fungus Beetles recorded feeding on Ascomycetes. A key to the species of Brachytrycherus known in China is provided.

RESUMEN

The genus Microcriodes Breuning is newly recorded from China upon the discovery of M. sikkimensis Breuning, 1943 and M. wuchaoi sp. n. from Motuo, Southeast Xizang. Illustrations of the habitus, genitalia including non-everted endophallus, as well as diagnostic features are provided.

RESUMEN

A new species, Distenia orientalis sp. n. is described from Southeastern China. It was misidentified as Distenia gracilis (Blessig, 1872) but can be separated from the latter by the color of antennae and legs, structure differences on scape, maxillary palp, pronotum, tibiae, punctures on elytra, etc. Three related species are carefully diagnosed and treated.
