description: Caputanurina sinensis sp. nov.
(Figs.1–12)
Type material. Holotype female, from the deciduous-conifer mixed forest of Mt. Qianshan, 41°05'N, 123°27' E, 190 m altitude, Anshan city, Liaoning Province, Northeast China, collected by Mr. Rongdong Xie and Mr.
Jun Zhang. Paratypes: 2 females, same data as holotype. Holotype and paratypes deposited in Shanghai Institute of Plant Physiology & Ecology, Shanghai, China.
Description. Holotype body length up to 0.69 mm. Color in alcohol spotted blue. Body oval, strongly flattened dorsoventrally. Strong tegumental granulation. Dorsal reticulation present from head to abd.V, except for intersegments (Fig.1).
Antennae shorter than head. Ant.I with 7 setae, ant.II with 12 setae. ant.III and ant.IV fused dorsally. Sensory organ of ant.III consisting of: two small sensilla bent in same direction, two subcylindrical guard sensilla (ventral s-shaped), and ventral microsensillum (Fig.2). Ant.IV with 6 thick subcylindric sensilla, dorsal external microsensillum, very small, distinct subapical organite, apical vesicle trilobate (Fig.2).
2+2 ocelli in lateral position (Fig.3). Postantennal organ latero-ventral, covered by integument folding, with 13–14 vesicles in circle (Fig.4).
Buccal cone ventral, short. Labium short, labial organite (x) consisting of 2 + 2 strong hyaline sensilla (Fig.5). Mandibles with 5 teeth (Fig.6). Maxillary capitulum with about 9 teeth (Fig.7), maxillary lamellae not visible.
Tibiotarsi I, II, III with 19, 19, 18 setae. Claws toothless (Fig.8). Femur with long ventral setae, one of them particularly long. Ventral tube with 4 + 4 setae (Fig.9). Vestigial furca reduced to two small mamelons with 1 + 1 setae (Fig.10). Abd.III and IV fused. Abd.VI completely hidden under abd.V. No anal spines. Anal plate is presented in Fig.11. Female genital plate as in Fig.12.
Dorsal chaetotaxy as in Fig.1: short, thin pointed ordinary setae and long, thin sensory setaes. Sensory chaetotaxy is "022/11111" per one-half tergite. Head with 3+3 dorsomedian setae.
Diagnosis. The new species is easily distinguished from all the known species of the genus Caputanurina by the fusion of Abd. III and IV. It differs also in the number of dorsomedial setae: 3+ 3 in C. sinensis, 5+ 5 in C. serrata and 2+ 2 in C. intermedia, C. turbator, C. major and C. sexdentata.
Etymology. The name sinensis refers to China, the country where the new species was found.
Remarks. We place the present new species into the genus Caputanurina because of its head with a V-like stitch along whole vertex, its Abd.V inverted V-like, its postantennal organ in the lateroventral position, its habitus dorsally flattened and its very strong dorsal reticulation. However, abd.III and IV of the new species is fused, but it is separate in the other known species of Caputanurina. We think it might be possible to establish a new genus if more species of this type are to be found in the future.
