Cisanthribus is a small genus in the family Anthibidae, subfamily Choraginae, tribe Cisanthribini [2]. On the first view, it does not look like the member of the family, since it is c. 1 mm long, globular and reddish. When examined in detail, it possess pseudotetramerous tarsi (similar to those also present in leaf beetles, Chrysomelidae), 11-segmented antenna with 3-segmented club, and protruding mandibles similar to other anthribids. Morimoto [3] provides a detailed illustrations of morphology. The beetles are flightless.
The genus has 4 species, one undescribed; species other than C. chinensis inhabit Pacific islands [2][4]. Cisanthribus chinensis was originally described from Hong Kong in the genus Glabrinotropis that is now a synonym of Cisanthribus [1]. Later, it was described under the name Cisanthribus nakenei from Ryukyus Islands, Japan [3]. It occurs in Hong Kong, Taiwan and most islands of Ryukyus [2].
Imada [2] documented that larvae of C. chinensis develop in dead leaf stalks of the palm Livistona chinensis.
Occurrence in Taiwan
The species has been reported from Kenting NP and Fuyuan (Hualien County) [2]. We are finding it infrequently in leaf litter samples at lowland localities in southern Taiwan. Since the palp Livistona chinensis does not occur at most localities where the beetle was found, we suppose its larvae may develop on a wider spectrum of host plants.
