Redescription of Leptispa abdominalis Baly, 1858 (Insecta: Coleoptera: Chrysomelidae: Cassidinae: Leptispini), Newly Recorded from Kinmen Island, with Notes on Its Biology

Abstract

Leptispa abdominalis Baly, 1858, formerly known from China and Vietnam, is recorded from Kinmen Island. The species is redescribed, and illustrations of diagnostic characters are provided, including pronotum, aedeagus, gonocoxae, and spermatheca. Adults and larvae of this species construct leaf-rolls on Bambusa similar to those of L. pygmaea Baly. 黃腹小扁鐵甲蟲 (Leptispa abdominalis Baly, 1858) 原本只分布在中國及越南，目前已在金門發現並作重新描述。針對診斷特徵以線圖描繪，包括前胸背板、雄性生殖器、雌蟲生殖突基節及雌蟲受精囊，並對其食草及捲葉行為做進一步的探討。
