Revision on Scolopendromorpha (Chilopoda) from Taiwan

by Chao, Jui-Lung

Abstract (Summary)
Between 1991 and 2002 three hundred and sixteen specimens of scolopendromorphs were collected from 100 sites in Taiwan. In total, 16 species (subspecies) of 5 genera, Scolopendra, Rhysida, Otostigmus, Cryptops, Scolopocryptops (formerly Otocryptops) were found. Three species are new by record to Taiwan, i.e., Scolopocryptops capillipedatus (Takakuwa, 1938), Scolopocryptops melanostomus melanostomus Newport, 1845 and Cryptops japonicus Takakuwa, 1934. A revisionary status, Scolopendra multidens Newport, 1844, formerly regarded as a subspecies of Scolopendra subspinipes by Kraepelin in 1903, is now a valid species, distinguished by the presence of genital appendages in males, margined tergites, and the presence of a tarsal spine on 20th leg. A new status, Scolopendra subspinipes japonica L. Koch 1878 maybe a subspecies or a geographic variation of Scolopendra multidens Newport, 1844, because they only differ in the color of head capsule and sternital paramedian sutures. But it must be demonstrated further. In the case of Scolopendra subspinipes mutilans, it may be a young S. subspinipes subspinipes, because they only differ in the color of head capsule and body size. Five previously recorded species and 2 subspecies were, however, not found on the island during this study. Based on body measurements, it is proposed that Rhysida longipes brevicornis Takakuwa, 1932 = Rhysida longipes longipes (Newport, 1845), Rhysida nuda brevicornuta Wang, 1951 = Rhysida immarginata immarginata (Porat, 1876), and Otostigmus insularis Hasse, 1887 = Otostigmus malayanus Chamberlin, 1914 = Otostigmus scaber Porat, 1876. We did not find any specimens resembling the description of Otostigmus multispinosus Takakuwa, 1937. It could have been misidentified, as the presence of a very similar species Otostigmus aculeatus Haase, 1887 on the island.
