Annamanum flavimaculatum sp. nov. is described and illustrated from Guizhou and Guangxi, China. Diagnosis for distinguishing the new species to its close congeners is presented and identification key to the genus is also updated.
Lamiinae, Leigongshan Nature Reserve, Lingui, Maoershan
The genus Annamanum Pic, 1925 is a large genus in the subfamily Lamiinae (Coleoptera, Cerambycidae) with 30 described species (
Specimens were collected by two collecting methods: net sweeping and six level Lindgren funnel traps (Sanyong Biologic Techonology Ltd, Xiamen, Fujian Province, China) with 99% ethanol as lure. Collected specimens were pinned or glued on pinned paper cards. Labels were handwritten or printed in Chinese. Materials from Guizhou are preserved in the School of Life Sciences, Guizhou Normal University, Guiyang, Guizhou, China. Materials from Guangxi are preserved in Collection of Wen-Xuan Bi, Shanghai, China.
Specimen examination and dissection were conducted under an AmScope SM-4TZ stereomicroscope. Adults were photographed with Canon EOS 6D digital camera equipped with EOS MP-E 65 lenses. Male genitalia were photographed with Olympus DP22 camera mounted on an Olympus SZX7 stereomicroscope.

The new species can be distinguished from its congeners by its unique elytral pattern: apical half of elytron mostly covered with dense yellow hairs that compose a large yellow marking; black hair clustered as dots near suture on the anterior half of the yellow marking, sometimes weakly forming a line, and then obliquely extending from suture backwards to elytral margin; small black hair clusters sparsely scattered within the yellow marking.
Body length
: 13.8–20.4 mm, male (Figure
The name refers to the yellow patch on the apical half of elytron.
