Naturk. Ser. A Nr. 490 83 S. Stuttgart, 30. 4. 1993 Terrestrial Isopoda (Crustacea) from Southern China, Macao and Hong Kong By Do Heon Kwon, Kimhae and Stefano Taiti, Florence With 325 figures / . 5 Summary 1UG0 Forty-nine species of terrestrial isopods are recorded from southern CFtk^jJMg^ok-ai^^ ^ Hong Kong. One new genus {Sinodillo) and 16 new species are described, viz. PapifiXpmlmm\x * granulata, P. arcangelü, Burmoniscus purpura, B. yunnanensis, B. ßavivertex, B. lobatus, ExalloniscHS silvestrii, Lucasioides pedimaculatus, (?)L. cavernicolus, Mongoloniscus nigrogra- nulatus, Troglodillo rotundatus, Sinodillo troglophilus, S. ferrarai, S. schmalfussi, Spherillo Orientalis, and Parakermania maculata. The foUowing poorly known species are discussed and illustrated: Tylos minor, Ligidium denticulatum, Nagurus sundaicus, N. pallidipennis, (f)N. verhoeffi, Lucasioides isseli, L. zavattarii, Dryadillo maculatus, and Spherillo raffaelei. Nagurus travancorius (Verhoeff) is considered to be a junior synonym of N. pallidipennis (Dollfus) and Porcellio hreviramus Shen oi Porcellionides pruinosus (Brandt). The composition of the oniscidean fauna from southern China is briefly discussed. Zusammenfassung Von Südchina, Macau und Hongkong sind 49 Arten von Landisopoden aufgelistet.

Nachfolgende, wenig bekannte, Arten sind kommentiert und illu- striert: Tylos minor, Ligidium denticulatum, Nagurus sundaicus, N. pallidipennis, (f)N. ver- hoeffi, Lucasioides isseli, L. zavattarii, Dryadillo maculatus und Spherillo raffaelei. Die fol- genden neuen Synonyme werden festgelegt: Nagurus travancorius (Verhoeff) = N. pallidi- pennis (Dollfus); Porcellio hreviramus Shen — Porcellionides pruinosus (Brandt).

Introduction This contribution deals with the terrestrial isopods from southern China including Macao and Hong Kong. The area under consideration is hmited to the north by the river Chiangjiang (= Yangtze), to the west by Myanmar (= Burma), to the south by Laos, Vietnam and the South China Sea, and to the east by the East China Sea. Some records from Sichuan, north of the river Chiangjiang, are also included. The terrestrial isopods from this part of China, as well as from the rest of the country and from many other parts of Far East Asia, have received very little atten- tion. Most of the Information available is due to Arcangeli (1927, 1952) who recorded 26 species from the whole of China, of which 23 occurred in southern China, Macao and Hong Kong. Other contributions are given by Budde-Lund (1885) who reported Ligia exotica Roux, 1828 from Chusan and Macao, by Shen (1949) who described six new species from Yunnan, and by Chen (1987) who recorded Ligia exotica from all the coastal provinces of China, together with L. occi- dentalis Dana, 1853 from Yantai (Shandong). Recently Taiti & Ferrara (1986b, 1986c, 1989), Ma (1990), Dudgeon, Ma & Lam (1990), Ma, Dudgeon & Lam (1991) and Ma, Lam & Dudgeon (1991) recorded nine species from Hong Kong, i. e. Tylos sp., Ligia exotica, Olibrinus sp., Armadilloniscus litoralis Budde-Lund, 1885, Littorophiloscia aldahrana Ferrara & Taiti, 1985, Burmoniscus ocellatus (Ver- hoeff, 1928), Exalloniscus rotundatus Taiti & Ferrara, 1986, Orodillo maculatus Arcangeli, 1952, and Formosillo raffaelei (Arcangeli, 1927). The study material was coUected by Dr. P. Beron (Sofia) in southern China, and by Dr. H. H. T. Ma (Hong Kong), Prof. P. Brignoli (L'Aquila), Prof. G. Osella (L'Aquila), and Prof. V. Cottarelli (Roma) in Hong Kong. Most of the specimens coUected by Prof. F. Sil- vESTRi (Portici) and recorded by Arcangeli (1927, 1952) were also re-examined.
