Treatment

Speocera ankalana Li & Li View in CoL sp. nov. ( Figs 3–4 View Figure 3 View Figure 4 , 55B View Figure 55 )

Material examined. Holotype ♂ ( IZCAS), Madagascar, Antsiranana Province, Ambilobe District, Ankalana National Park (12º57.010′S, 49º07.021′E), elev. 140 m, 16.XII.2016, leg. H. Zhao. Paratype 1♀ ( IZCAS), same data as holotype GoogleMaps .

Etymology. The specific name is derived from the type locality; noun.

Diagnosis. The new species is similar to S. transleuser Deeleman-Reinhold, 1995 , but males can be distinguished by the laterally strongly excavated chelicerae ( Fig. 55B View Figure 55 ) and the elliptical palpal bulb ( Figs 3A–B View Figure 3 ), and the females by the very short, straight afferent spermathecae ( Fig. 4A View Figure 4 ). S. transleuser males have antero-posteriorly compressed chelicerae and a nearly flattened palpal bulb, and females have long, curved afferent spermathecae (Deeleman-Reinhold, 1995: figs 257– 260).

Description. Male. Total length 0.96; carapace length 0.47; carapace width 0.41; abdomen length 0.45; abdomen width 0.28. Prosoma: carapace pyriform, narrowing gradually anteriorly, anterior margin smoothly curved in dorsal view; light yellow, suffused with purplish pattern ( Fig. 4C View Figure 4 ); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, as long as wide. Endites light yellow suffused with purplish tinge; with serrula; labium light yellow suffused with purplish tinge. Clypeus nearly vertical; short. Chelicerae light yellow; external margin strongly excavated; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles ( Fig. 55B View Figure 55 ). Eyes: six contiguous eyes surrounded by black pigmentation, PME smallest, PLE largest ( Fig. 4C View Figure 4 ). Opisthosoma oval; purplish. Legs missing. Genitalia ( Fig. 3 View Figure 3 ). Palpal femur long; palpal tibia elongated, about 1.6 times as long as cymbium ( Figs 3A–B View Figure 3 ). Cymbium conical, without prolateral extension. Bulb elliptical, much longer than wide. Embolus short, black, associated sclerites beltlike; sperm duct initially medium sized, becoming very narrow distally ( Fig. 3D View Figure 3 ).

Female. Total length 1.23; carapace length 0.48; carapace width 0.40; abdomen length 0.70; abdomen width 0.56. Similar to male in color and general features ( Figs 4C–D View Figure 4 ) but larger. Chelicerae unmodified. Legs light yellow; I, II, IV missing; III 1.46 (0.41, 0.14, 0.38, 0.29, 0.23). Genitalia. Internal genitalia with afferent spermathecae short, straight, not extending past the sides of the abdomen; tip of the afferent spermathecae question mark shaped ( Fig. 4B View Figure 4 ); spermathecae oval ( Fig. 4A View Figure 4 ).

Distribution. Known only from the type locality.
