Notiocoelotes orbiculatus View in CoL sp. nov.

( Figs 4–7 View FIGURE 4 View FIGURE 5 View FIGURE 6 View FIGURE 7 and 16 View FIGURE 16 )

Type material: Holotype male ( IZCAS), Mt. Limushan Nature Reserve (19.2ºN, 109.7ºE, Alt: 653m), Hainan Island, China, 12 August 2007, Shuqiang Li, Chunxia Wang, Linghui Lin and Jianjun Xu leg. GoogleMaps Paratypes: 10 females ( IZCAS), same data as holotype GoogleMaps .

Etymology: The specific name is taken from the Latin adjective orbiculatus and refers to the global spermathecae, adjective.

Diagnosis: The new species is similar to N. spirellus sp. nov. in having the elongated palpal tarsus and tibia ( Figs 4 View FIGURE 4 , 5A View FIGURE 5 , 6B–D View FIGURE 6 , 12 View FIGURE 12 , 13A View FIGURE 13 , 14B–D View FIGURE 14 ), absence of cymbial furrow ( Figs 4B View FIGURE 4 , 6D View FIGURE 6 , 12B View FIGURE 12 , 14D View FIGURE 14 ), small palpal bulb ( Figs 4 View FIGURE 4 , 5A View FIGURE 5 , 6B–D View FIGURE 6 , 12 View FIGURE 12 , 13A View FIGURE 13 , 14B–D View FIGURE 14 ), spiral spermathecal heads and almost global spermathecae ( Figs 5C–D View FIGURE 5 , 7C–D View FIGURE 7 , 13C–D View FIGURE 13 , 15C–D View FIGURE 15 ), but can be distinguished by the following differences: 1, the small ventral branch of lateral tibia apophysis ( Figs 4B View FIGURE 4 , 6D View FIGURE 6 , 12B View FIGURE 12 , 14D View FIGURE 14 ); 2, the relatively short conductor that not reaching the base of embolus ( Figs 5A View FIGURE 5 , 6C View FIGURE 6 , 13A View FIGURE 13 , 14C View FIGURE 14 ); 3, the shield-shaped, longer than wide atrium ( Figs 5B View FIGURE 5 , 7B View FIGURE 7 , 13B View FIGURE 13 , 15B View FIGURE 15 ); 4, the relatively short and slightly spiral spermathecal heads ( Figs 5C–D View FIGURE 5 , 7C–D View FIGURE 7 , 13C–D View FIGURE 13 , 15C–D View FIGURE 15 ).

Chelicerae with the same teeth as that of male. Epigynum without epigynal teeth ( Figs 5B View FIGURE 5 , 7B View FIGURE 7 ); atrium small, almost rectangular ( Figs 5B View FIGURE 5 , 7B View FIGURE 7 ); atrial scape distinct, extending behind the posterior epigynal margin ( Figs 5B View FIGURE 5 , 7B View FIGURE 7 ); copulatory ducts small, anteriorly originating ( Figs 5C–D View FIGURE 5 , 7C–D View FIGURE 7 ); spermathecae moderately large, global, widely separated ( Figs 5C– D View FIGURE 5 , 7C–D View FIGURE 7 ); spermathecal heads slightly spiral, situated posteriorly and widely separated from each other, extending anteriorly ( Figs 5C–D View FIGURE 5 , 7C–D View FIGURE 7 ).
