A new soil centipede from south-east Asia with a unique arrangement of ventral glands, and a revised synopsis of gonibregmatidae (Chilopoda, Geophilomorpha)

Abstract

A new gonibregmatid centipede, Vinaphilus unicus gen. n., sp. n., is described based on two females from a single location in northern Vietnam. The new genus and species are distinguished mainly by the arrangement of the ventral pore-fields, which is unique among all Chilopoda. A critically revised synopsis of the Gonibregmatidae is also given. In particular, three species are provisionally recognized in Himatosoma Pocock, 1891: H. bidivisum Silvestri, 1919, H. porosum Pocock, 1891 (= H. typicum tridivisum Silvestri, 1919, syn. n.), and H. typicum Pocock, 1891. The genera Dschangelophilus Verhoeff, 1937 and Tweediphi-lus Verhoeff, 1937, with their species D. coloratus Verhoeff, 1937 and T. malaccanus Verhoeff, 1937, are moved to the Gonibregmatidae, whereas Geoporophilus aporus Attems, 1930 is moved to the Oryidae as Orphnaeus aporus (Attems, 1930), comb. n.
