本文报道了台湾台北一种四环生大翅蝽属(Orobdella ketagalan sp. n.)新种。这是台湾首次记录到斑腹蝉和斑腹蝉科。这个新物种在雄性生殖系统中拥有小而成对的精子管球。除了这些鳞茎外,该新种还具有以下特征组合,使其区别于其他四环生种:单环生体IV,雄性性腺孔在XI b6,雌性性腺孔在XIII a1,性腺孔之间的1/2 + 4 + 1/2,单管状胃门管,缺乏附睾,心房角不发达。利用核18S rDNA和组蛋白H3以及线粒体COI、12S rDNA、tRNAVal和16S rDNA标记进行系统发育分析表明,Orobdella ketagalan与两个琉球群岛物种Orobdella dolichopharynx Nakano, 2011和Orobdella shimadae Nakano, 2011有亲缘关系。
A new quadrannulate species of Orobdella, Orobdella ketagalan sp. n., from Taipei, Taiwan, is described. This is the first record of Orobdella and the family Orobdellidae from Taiwan. This new species possesses small, paired sperm duct bulbs in the male reproductive system. In addition to these bulbs, the following combination of characters distinguishes this new species from other quadrannulate species: somite IV uniannulate, male gonopore at XI b6, female gonopore at XIII a1, 1/2 + 4 + 1/2 between gonopores, simple tubular gastroporal duct, lacking epididymides, and undeveloped atrial cornua. Phylogenetic analyses using nuclear 18S rDNA and histone H3 as well as mitochondrial COI, 12S rDNA, tRNAVal, and 16S rDNA markers showed that Orobdella ketagalan is related to the two Ryukyu Archipelago species Orobdella dolichopharynx Nakano, 2011 and Orobdella shimadae Nakano, 2011.
