Abstract

Phylogenetic relationships within the Dascillinae were investigated. Eighteen ingroup taxa and two outgroups were included in cladistic analysis, based on 30 characters derived from adult morphology. Six genera are recognised in Dascillinae: Coptocera Murray, Dascillus Latreille, Metallidascillus Pic, Notodascillus Carter, Petalon Schoenherr and Sinocaulus Farimaire. Pseudolichas Fairmaire, 1878 (TS: P. sulcifrons Fairmaire, 1878) is recognised as a junior synonym of Petalon Schoenherr, 1833 (TS: Bruchus fulvulus Wiedemann, 1819) syn. nov. All valid genera of Dascillinae are thoroughly described, illustrated and key to their identification is provided. Species level keys are provided for Old Wold Dascillus, Petalon and Sinocaulus.

Eighteen new species are described: Dascillus acutus (China: Shanxi), D. chifengi (China: Taiwan), D. compressus (Nepal), D. formosanus (China: Taiwan), D. lanceus (China: Taiwan), D. largus (China: Hubei), D. montanus (China: Sichuan), D. planus (China: Yunnan), D. russus (India: Arunachal Pradesh), D. tibetensis (China: Tibet), D. transversus (China: Yunnan), Petalon acerbus (China-Yunnan), P. allochroides (Malaysia, Sabah), P. annamensis (Vietnam), P. digitatus (China: Yunnan), P. iviei (China: Yunnan), Sinocaulus clypeatus (China: Guizhou) and S. omiensis (China: Sichuan).

The following species level new synonyms are proposed (senior synonym listed first): Dascillus congruus Pascoe, 1860 (= Dascillus perroudi Pic, 1939, D. klapperichi, Pic, 1955, D. taiwanus Nakane, 1995 and D. fortunei Pic, 1913); Dascillus calvescens Bourgeois, 1892 (= D. holzi Pic, 1911, D. rufocinctus Pic, 1913, D. brevesulcatus Pic, 1933 and D. rubropubens Pic, 1934); Dascillus renardi Bourgeois, 1891(= D. rufovillosus Bourgeois, 1892); Dascillus fulvulus (Wiedemann, 1819) (= D. striatus Pic, 1911, D. corporaali Pic, 1923 and D. obscuricolor Pic, 1933); D. obscuripes Pic, 1912 (= D. rufus Pic, 1923); Pseudolichas nivipictus Fairmaire, 1904 (= Pseudolichas ruficornis Pic, 1914) and Sinocaulus rubrovelutinus Fairmaire, 1878 (= Haematoides atriceps Pic, 1910: 45).

Four taxa are transferred to Dascillus Latreille (Cladotoma vittata Pic, 1914; Pseudolichas nigronotatus Pic, 1914; Pseudolichas nivipictus Fairmaire, 1904; Pseudolichas superbus Pic, 1907 and Therius jaspideus Fairmaire, 1878) comb. nov.

Fifeteen species are transferred to Petalon Schonherr (Dascillus bengalensis Pic, 1911; D. birmani
