title: Supplementary descriptive notes of the Sinella and Coecobrya (Collembola: Entomobryidae) species from North America, Hawaii and Japan.
abstract: Many known collembolan species lack sufficient descriptive details so that further taxonomical comparison cannot be achieved. When sorting documents and materials from Prof. Jian-Xiu CHEN, Nanjing University, we found many old but valuable drafts on Sinella and Coecobrya species from North America, Hawaii and Japan. Supplementary descriptions, particularly chaetotaxy, were provided for the following species: S. agna Christiansen & Bellinger, 1980, S. alata Christiansen, 1960, S. baca Christiansen & Bellinger, 1980, S. barri Christiansen, 1960, S. hoffmani Wray, 1952, S. sexoculata (Schött, 1896), S. straminea (Folsom, 1899), S. yosiia Christiansen & Bellinger, 1992, C. akiyoshiana Yosii, 1956, C. borerae Christiansen & Bellinger, 1992, C. ishikawai Yosii, 1956, C. kukae Christiansen & Bellinger, 1992, C. lua Christiansen & Bellinger, 1992, C. nupa Christiansen & Bellinger, 1992, C. tibiotarsalis Yosii, 1964. Sinella cavernarum (Packard, 1888) was redescribed based on topotypes and more additional materials.
