Stenohya bomica Zhao & Zhang, 2011 (波ẑ狭伪$) Figs 1.3, 9–11, 71A Stenohya bomica Zhao & Zhang, 2011: 299–302, fig. 1a–j. Revised diagnosis Tritonymph pedipalpal femur 3.97 times as long as broad; pedipalpal patella 2.67 times as long as broad; trichobothrium of ist situated medially between et -est -it and eb -esb -ib. Material examined Holotype CHINA • tritonymph; Xizang Autonomous Region, Bomi County; 29°50′ N, 95°45′ E; 26 Apr. 1986; Fusheng Huang leg.; Ar.- MHBU-XZ860426. Paratype CHINA • one tritonymph, same collection data as for holotype. Distribution China: Xizang Autonomous Region. Remarks The holotype and paratype of S. bomica were considered as two adult females by Zhao & Zhang (2011) originally.However, after inspection of the type material, we believe these two specimens are tritonymphs. The number of trichobothria is an important feature to judge the maturity of the pseudoscorpiones: protonymph with four trichobothria, deutonymph with eight trichobothria, tritonymph with 10 trichobothria, adult with 12 trichobothria (Harvey 1992). The holotype of S. bomica has 10 trichobothria on the left pedipalpal chela, seven on the fixed finger and three on the movable finger (Fig. 10D–E), while its right pedipalpal chela has 11 trichobothria, seven on the fixed finger and four on the movable finger (Fig. 10A, C). The unusual number of trichobothria on the right pedipalpal chela of the holotype is a result of growth deformity. The extra ‘trichobothrial socket’ between t and st is significantly smaller than the others (Fig. 10B); it may be a specialization of ordinary seta. The paratype also has 10 trichobothria on both the left and right pedipalpal chela (Fig. 11). As a result, the type material of S. bomica are two tritonymphs, both lacking the trichobothria isb and sb.
