| Abstract |
Tribe Nedyopodini Jeekel, 1968 only contained a genus Nedyopus which was established byAttems (1914) contained how many valid species is a puzzle all along because the poor descriptions, lacking illustrations, or misidentifications. Making use of stereomicroscope and scanning electron microscope to comparing type specimens and new materials, and checking the old literatures, there were twenty-two species/subspecies/variety turn out fourteen species are valid, among them, a subspecies and a variety are promoted as species status, seven species/subspecies are new synonyms, one species N. dawydoffiae (Attems, 1953) is deleted. Besides, there are five new species being added. Totally, there are nineteen species in genus Nedyopus so far. The diagnosis of genus Nedyopus/tribe Nedyopodini is amended. Provide a key and distribution map in the world which shows genus Nedyopus are warm temperate (mainly)–tropical East and Southeast Asian creatures, and Taiwan
should be its main hotspot by owing a high species diversities in genus Nedyopus. Making use of paup running maximum parsimony analysis and Mr.Bayes 3.2.2 running Bayesian inference analysis to develop the phyletic relationships of genus Nedyopus based on morphological characters, and the results supported genus Nedyopus is monophylic with 100% bootstrap value and two nonhomoplastic synapomorphies in maximum parsimony analysis, and N. pictus (Brölemann, 1916) is basal lineage. Quite a few deepest derived species placed in Japan and Taiwan which shows these two localities are advantages for genus Nedyopus speciation. According the cladistics analysis, gonopodal traits are still better characters than somatic traits in study phylogeny because higher RC values. Solenophore lobe B of genus Nedyopus developed first in the evolutionary history showed its importance in copulation. |
