Speocera tubularis Li & Li

sp. nov.

Speocera tubularis Li & Li   sp. nov. ( Figs 47–48 View Figure 47 View Figure 48 , 57C View Figure 57 )

Material examined. Holotype ♂ ( CAS), Madagascar, Toliara Province, Andohahela National Park , rainforest near stream surrounded by disturbed slash/burn forest (24º45.501′S, 46º51.235′E), elev. 100 m, 12.XII.2008, leg. F. Alvarez- Padilla & H. Wood. Paratype 1♀ ( CAS), same data as holotype GoogleMaps   .

Etymology. The specific name is from Latin and refers to the tubular shaped female spermathecae; adjective.

Diagnosis. The new species is similar to S. ankalana Li & Li   sp. nov., but males can be distinguished by the laterally slightly curved chelicerae ( Fig. 57C View Figure 57 ) and the short male palpal tibia that is 1.2 times as long as cymbium ( Figs 47A–B View Figure 47 ) and females by the tubular shaped spermathecae ( Fig. 48A View Figure 48 ). S. ankalana   males have the chelicerae laterally strongly excavated ( Fig. 55B View Figure 55 ) and the palpal tibia 1.6 times as long as the cymbium ( Figs 3A–B View Figure 3 ), and the females have oval spermathecae ( Fig. 4A View Figure 4 ).

Description. Male. Total length 0.85; carapace length 0.41; carapace width 0.36; abdomen length 0.44; abdomen width 0.31. Prosoma: carapace wide oval, narrowing gradually anteriorly; light yellow, suffused with purplish pattern ( Fig. 48C View Figure 48 ); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, as long as wide. Endites light yellow with serrula; labium light yellow. Clypeus nearly vertical; short. Chelicerae light yellow; external margin slightly curved; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles ( Fig. 57C View Figure 57 ). Eyes: six contiguous eyes surrounded by black pigmentation, PME smallest, PLE largest ( Fig. 48C View Figure 48 ). Opisthosoma oval; light gray. Legs missing. Genitalia ( Fig. 47 View Figure 47 ). Palpal femur long; palpal tibia about 1.2 times as long as cymbium. Cymbium conical, without prolateral extension. Bulb spherical ( Figs 47A–B View Figure 47 ). Embolus short, black, associated sclerites belt-like; sperm duct initially wide, narrowing distally ( Fig. 47D View Figure 47 ).

Female. Total length 0.92; carapace length 0.42; carapace width 0.37; abdomen length 0.49; abdomen width 0.31. Similar to male in color and general features ( Figs 48D–E View Figure 48 ) but larger. Chelicerae unmodified. Legs light yellow; leg lengths I 1.53 (0.45, 0.14, 0.43, 0.29, 0.23); II 1.78 (0.79, 0.13, 0.38, 0.27, 0.22); III 1.20 (0.34, 0.13, 0.29, 0.25, 0.20); IV missing. Genitalia. Internal genitalia with afferent spermathecae short, straight, not extending past the sides of the abdomen; tip of the afferent spermathecae shaped like a large question mark ( Fig. 48B View Figure 48 ); spermathecae long, tubular ( Fig. 48A View Figure 48 ).

Distribution. Known only from the type locality.
