Abstract

The hydrophilid genusCycreonOrchymont, 1919, previously known from two historical specimens only, is reviewed based on the numerous material collected recently from the inflorescences of various Araceae species in the Malay Peninsula and Borneo. Four species are recognized in the genus:C.sculpturatusOrchymont, 1919 from Sumatra,C.armandiShatrovskiy, 2017 from Singapore,C.adolescenssp. n.from peninsular Malaysia, andC.floricolasp. n.with two subspecies, the nominotypical one from Peninsular Malaysia, andC.floricolaborneanussubsp. n.from Borneo. All species are very similar, differing only by the pronotal punctation, shape of the clypeus and the mentum, and the form of the median lobe of the aedeagus. Specimens ofC.floricolasp. n.andC.adolescenssp. n.were collected from inflorescences of various genera of the family Araceae. The field observations and analysis of mid gut contents indicates that they feed on organic material on internal organs of the inflorescences, including the pollen of the host plant. They were also observed to carry a large amount of pollen and are likely pollinators of their host species of Araceae.

花栖食水甲虫属综述(鞘翅目，亲水甲虫科)、新种描述及生物学研究进展

摘要根据近年来在马来半岛和婆罗洲收集到的天南星科各种植物的花序资料，对喜水属cycreonorchymont, 1919进行了综述。属中有四种:C。奥奇蒙特(orchymont)， 1919年，摄于苏门答腊岛。armandiShatrovskiy, 2017来自新加坡，c .青春期。来自马来西亚半岛，和c .floricolasp。有两个亚种，来自马来西亚半岛的命名典型的一个，和c .floricolaborneanussubsp。n.from婆罗洲。所有的种类都非常相似，不同之处在于前额的标点，叉形和动量的形状，以及aedeagus中间叶的形式。标本ofC.floricolasp。n.andC.adolescenssp。从天南星科各属的花序中采集。野外观察和对中肠内容物的分析表明，它们以花序内部器官上的有机物为食，包括寄主植物的花粉。它们还被观察到携带大量花粉，可能是天南星科寄主物种的传粉者。

期刊介绍： Founded in 1857 as Berliner Entomologische Zeitschrift, Deutsche Entomologische Zeitschrift is one of the World''s oldest international journals of systematic entomology. It publishes original research papers in English on the systematics, taxonomy, phylogeny, comparative morphology, and biogeography of insects. Other arthropods are also considered where of relevance to the biology of insects. The geographical scope of the journal is worldwide. Deutsche Entomologische Zeitschrift (DEZ) is dedicated to provide an open access, high-quality forum to contribute to the documentation of insect species, their distribution, their properties, and their phylogenetic relationships. All submitted manuscripts are subject to peer-review by the leading specialists for the respective topic. The journal is published in open access high-resolution PDF, semantically enriched HTML and machine-readable XML versions.
