In the world, the subfamily Eucradinae LeConte, 1861 contains two tribes, Eucradini LeConte, 1861, with the North American genus Eucrada LeConte, 1861 and Hedobiini Mulsant et Rey, 1868, with five genera distributed worldwide, AnhedobiaNakane, 1963, Clada Pascoe, 1887, Hedobia Dejean, 1821, Neohedobia Fisher, 1919 and Ptinomorphus Mulsant et Rey, 1868 (Zahradník and Trýzna, 2018). From them 4 genera have been known until now (AnhedobiaNakane, 1963;Clada Pascoe, 1887, Hedobia Dejean, 1821, Ptinomorphus Mulsant & Rey, 1868) with 22 species distributed in China, Japan, and Taiwan (Zahradník, 2007;2013). In case of genus Anhedobia, only two species, A. capucina and A. dulcis are recorded in China and Japan (Zahradník, 2007;2013).

In this paper, we report Anhedobia capucina (Reitter, 1877) for the first time in the Korean fauna. We collected this species from western part and southern islands of Korean Peninsula.

Materials and Methods

All materials for this study were collected with Lindgren funnel trap and deposited in the collection of Research Institute of Forest Insect Diversity (RIFID, Namyangju, Korea) and Nakdonggang National Institute of Biological Resources (NNIBR, Sangju, Korea). The important morphological characters were studied using a stereoscopic microscope (S8Apo, Leica, Heerbrugg, Switzerland). Photographs were taken with Canon 5D digital camera and Canon Macro Photos Lens MP-E 65 (Canon, Tokyo, Japan). The final deep focus images were created with Helicon Focus 7.7.4 stacking software. Adobe Photoshop 22.2.0 was used for post-processing.

Diagnosis. Body length 2.7-4.87mm. Body oblong and body color reddish brown except dark brown lateral and posterior part of elytra. Head conealed under pronotum but round and convex eyes clearly visible from above. Antennae 11 segmented without club. First antennomere slightly thicker than other antenomeres. Second antenomere smaller than 3^rd one and 3^rd one triangular and as long as 4^th one. Fifth to 10^th antenomeres same size with each other and longer than wide. Eleventh antennomere 1.6 times longer than 10^th one. Pronotum with distinct longitudinal carination at middle. Lateral margin of pronotum widest at before posterior angle and abruptly narrowing toward posterior margin. Widest area of lateral margin slightly narrowing anteriorly until behind middle, abruptly narrowing at middle, and then smoothly narrowing anteriorly. Anterior margin of pronotum rounded. Each side of highest area of carination of pronotum with a bundle of yellowish erected hairs. Elytra covered with yellow, white, and black pubescences patches and minute tubercles without any punctures or strioles. Posterior margin of elytra slightly emarginated at middle.
