本文记述贵州省倍足类一新种——方钩雕马陆Glyphiulus quadrohamaius sp.nov.,其鉴别特征为:颈板前部有14条,后部有11条纵脊;后环背板上的前、后列雕饰在体前部分别有10和9个,在体后部分别有12和11个瘤突;雄性第1对足退化,两基节突相距颇远,端肢仅为1对极小的结节;前生殖肢基节突的内角突起短,其端部内折呈方钩状;后生殖肢末节伸出刀状弯曲的一枝,其内缘极度扩张成具细密锯缘的薄片。
A new species of the genus Glyphiulus Gervais, 1847 collected from Guizhou Province is described in this paper and named Glyphiitlus quadrohamatus.Clyphialus quadrohamatus sp. nov. (figs. 1-8)Holotype ♂, allotype ♀, paratypes 12♂♂, 6♀♀, collected from Zhenning Bouyizu Miao-zu Autonomous County (E 105°46', N 26°3') (Shang Cave), August 3, 1986, and Puding County (E 105°45', N 26°18') (Hou Er Cave, Dui Men Cave), July 21-24, 1986, deposited in Department of Biology, Nanjing University.Body color greyish brown. Length 28-49mm, greatest width 1.60-2.00 mm in both sexes. Segments 51-78. Collum nearly transversely quadrate, with 14 longitudinal crests at front margin and 11 at hind margin, those on lateral sides narrow and conspicuous, and those on the middle part broad, flat, and ambiguous. Metazonites of body anterior part with 10 tubercles in anterior row and 9 in posterior row; those of body posterior part with 12 in anterior row and 11 in posterior row. Coxosternal processes of male first pair of legs small, stump-shaped, located apart from each other, telopodites reduced in to a pair of very small tubercles with 2-4 setae on each. Inner corner of each coxal process of anterior gonopods protruded and bent as a short quadrate hook. Each telopodite of posterior gonopods bearing a slender, curved, and sword-shaped branch with inner edge extremely produced into a thin, broad, serrated lamina.The new species is very closely related ro G. adeloglyphus Zhang et Li, 1982, but easily distinguished from the latter by: a) 3 labral teeth; b) ornamentation on collum and body segments; c) short, quadrate hook-shaped inner corner processes of coxal processes of anterior gonopods; d) a thin, broad, serrated lamina on inner edge of each telopodite branch of posterior gonopods; e) male first pair of legs with distal end of each coxosternal process bent forward, and with rudimental telopodites as a pair of very small tubercles with setae.
