摘要

The genus Lycocerus Gorham, 1889 is a highly speciose group of Asian soldier beetles. Okushima (2005) divided this genus into several species groups and presumed their potential phylogenetic relationship based on anatomical comparison, and a few more species groups were subsequently proposed by various authors. In this study, I reinvestigated the relationship within Lycocerus using phylogenetic analyses of morphological data and extended the taxa sampling to corroborate all currently known major lineages. The resulting topology only partially agrees with Okushima (2005), but supports the synonymy of Athemus Lewis, 1895, Athemellus Wittmer, 1972, Mikadocantharis Wittmer & Magis, 1978, Andrathemus Wittmer, 1978 and lsathemus Wittmer, 1995 with Lycocerus.

異菊虎屬（Lycocerus Gorham, 1889）是多樣性極高的亞洲產菊虎類群。Okushima（2005）將本屬劃分成數個種群並基於形態解剖比較推測異菊虎屬內的親緣關係，此後又有數位學者提出數個異菊虎種群。在本研究中，我們基於形態數據，透過系統發育分析重新探討異菊虎的屬內關係，並將取樣範圍延伸到目前已知主要的菊虎支系。分析結果與Okushima（2005）提出推測的樹型僅部分一致但支持其提出的異麗菊虎（Athemus Lewis, 1895）、細身異麗菊虎（Athemellus Wittmer, 1972）、米卡菊虎（Mikadocantharis Wittmer & Magis, 1978）、安卓麗菊虎（Andrathemus Wittmer, 1978）和伊斯麗菊虎（lsathemus Wittmer, 1995）為異菊虎的同物異名處理。
