本文报道了中国叶螨科的一个新属、一个新种，并建立了一个新族群。模式标本保存于上海农学院。中华蝾螈族十一月中华拟兽属部落。与 Bryobiini 相似，具有钩爪和有十毛的垫状绒毛，但其独特之处在于有两对肛门刚毛和须跗节上的一个小末端感器。模式种：Sinobryobia chinensis sp. 11.身体长。前足体在颌体上有两个突出的叶。前足有四对背刚毛，第一对位于肋骨上。须的跗骨有一个小的末端感器。子宫体有九对背侧骨，外部骶骨缺席。有两对肛刚毛，一对后肛旁刚毛。前肛旁刚毛。缺席的。真正的法则是钩状的。 Empodium 垫状，均具租户毛。跗节Ⅰ有两对双刚毛，跗节Ⅱ有一对双刚毛。十一月（图1-Ⅱ）雌性：体长（含吻部）459μ，宽203μ，体长椭圆形。须具六刚毛，末端感觉器圆柱状。周孔远端不规则地吻合。前足在颌体上方有两个突出的裂片，并有四对背刚毛，第一对位于裂片上。子宫体有九对背刚毛，骶骨缺如。所有背刚毛都非常小，呈披针形，除了第二对前足体背刚毛和弯刚毛较大且呈扇形。后体有两对肛门和一对后肛门，无肛门旁。真爪钩状，各有一对内毛。呈垫状，有六对或更多对的毛。腿Ⅰ-Ⅳ节上的刚毛编号如下：基节2、2、1、1；转子各1个；股骨11,7,5,5;膝6,3,3,3;胫骨 10,5,5,5;跗节 19,12,10,10。男性：未知。正模 (?)，副模 (?)，Ⅵ。 1980年12月17日，江西高安，杂草上，陈希文收藏。
This paper reports a new genus and species and erects a new tribe of Tetranychidae collected from China. The type specimens are kept in Shanghai Agricultural College. Sinobryobiini trib. nov. Sinobryobiini n. trib. is similar to the Bryobiini in having uncinate claws and padlike empodium with tenent hairs, but it is distinctive in having two pairs of anal setae and a small terminal sensillum on tarsus of palpus.Sinobryobia gen. nov.Type species: Sinobryobia chinensis sp. nov.Body long. Propodosoma with two prominent lobes over the gnathosoma. Propodosoma with four pairs of dorsal setae, the first of them set on the lebes. Tarsus of palpus with a small terminal sensillum. Hysterosoma with nine pairs of dorsal r-etae, the external sacrales absent. With two pairs of anal setae, one pair of posterior para-anal setae. Anterior para-anal setae. absent. True elaws uncinate. Empodium pad-like, both with tenent hairs. Tarsus Ⅰ with two pairs of duplex setae, tarsus Ⅱ with one pair of duplex setae.Sinobryobia chinensis sp. nov. (figs. 1-Ⅱ)Female: Length of body (including rostrum) 459 μ, width 203 μ, body longoval.Palpus with six setae, terminal sensillum cylinder-like. Peritreme irregularly anastomosing at distal end. Propodosoma with two prominent lobes over the gnathosoma and with four pairs of dorsal setae, the first one set on the lobes. Hysterosoma with nine pairs of dorsal setae, the external sacrals absent. All dorsal setae very small, lanceolate except the second pair of pro-podosomal dorsals and clunals, which are large and fan-like. Opisthosoma with two pairs of anals and a single pair of post-anals, the para-anals absent.True claws uncinate, each with one pair of tenent hairs. Empodium pad-like with six or more pairs of tenent hairs. Setae on segments of leg Ⅰ-Ⅳ numbered as follows: coxae 2,2,1,1; trochanters 1 each; femora 11,7,5,5; genua 6,3,3,3; tibiae 10,5,5,5; tarsi 19,12,10,10.Male: unknown.Holotype (?), paratype (?), Ⅵ. 17, 1980, Gaoan, Jiangxi Province, on weed, collected by Chen Xi-wen.
