( Figure 2A–K View Figure 2 )
Material
Holotype male. Found in Feilong Cave (24°55¢ N, 104°53¢ E, 1335 m above sea level), Shangjiao village, Jingnan town , Xingyi city, Guizhou province, 25 May 2004, collected by H.M. Chen and Y.Q. Zhang ( MLR).
Paratypes. Three males and one female, same data as holotype ( MHBU) .
Diagnosis
The new species is similar to T. dongbei , T. spina . Male T. feilong can be distinguished from other Telema species by different shapes of bulb ( Figure 2C,D View Figure 2 ); from T. dongbei by short triangular bulbal apophysis (tapering in T. dongbei ), the> 90° angle of bulbal apophysis to the bulb (<90° in T. dongbei ); from T. spina by absence of eyes, absence of strong spines in palpal tarsus. Females can be distinguished by different shapes of their spermathecal tubes ( Figure 2J View Figure 2 ).
