Abstract in another language

The pygidial gland of Crawling Water Beetles (Coleoptera: Haliplidae): Morphology,Chemistry, Function and Phylogenetic Significance. – The minute paired abdominalpygidial glands of crawling water beetles (Coleoptera: Haliplidae) were analyzedmorphologically and chemically by prechromatographic derivatizations. Apart fromthe already known phenylacetic acid (3) in Peltodytes caesus, P. rotundatus, Brychiuselevatus, Haliplus (Neohaliplus) lineatocollis, Haliplus (Haliplus) ruficollis,H. (Haliplus) heydeni, Haliplus (Liaphlus) fulvus, H. (Liaphlus) flavicollis, andH. (Liaphlus) laminatus the following antimicrobic and the body surface wettingcompounds were analyzed for the first time: 3-hydroxyoctan- (1) and 3-hydroxydecanoicacids (2), 4-hydroxy- (4) and 3-hydroxyphenylacetic acids (6), phenyllactic acid(5) and benzoic acid (7). Especially by regarding the glandular tissue, the collectingchannel, and the gland reservoir a phylogenetic arrangement of the taxa Brychius,the subgenus Neohaliplus and the remaining representatives of the genus Haliplusindicates that they represent a monophylum with Peltodytes and Neohaliplus asprimitive representatives. In contrast the gland morphology of both Peltodytes representativesresembles the Geadephaga whereas the subgenera Liaphlus and Haliplusare mostly derived.
