Etymology

The specific name is Latin for axe and refers to the shape of the anterior lobe of the bulb.

Differential diagnosis

The male differs from that of other species in having an unique anterior lobe of the bulb, broadening distally, with a small triangular process on the prolateral edge at mid-length ( Fig. 11E ). The female is easily recognized from congeners by the unique structure of the epigyne with relatively weakly sclerotized atria and long seminal ducts ( Fig. 12A–B ).

Description

Male

DIMENSIONS. Cephalothorax: length 2.2–2.3, width 1.7–1.8, height 1.1–1.2. Eye field: length 1.0–1.1, anterior width 1.6–1.7, posterior width 1.4–1.5. Abdomen: length 1.9–2.1, width 1.4–1.5.

COLOUR AND BODY. General appearance as in Fig. 11A . Carapace dark brown, black line along edges of carapace, white hairs on slopes and on foveal area. Anterior median eyes lack black rings but encircled by fawn scales, fawn hairs on eye field ( Fig. 11B ). Clypeus brown. Chelicera with an unusually large promarginal tooth ( Fig. 11C ). Mouthparts brownish, sternum yellow. Abdomen greyish beige to dark brown, with yellow serrated band medially ( Fig. 11A ), venter dark with four lines formed by white dots. Spinnerets dark. First pair of legs dark brown, metatarsus and tarsus lighter. Other legs brownish with darker femora. Coxae and trochanters of all legs pale.

GENITALIA. Pedipalps brown, cymbium clothed in dense pale hairs. Palpal organ as in Fig. 11D–H , bulb with characteristic wide anterior lobe. Dorsal apophysis slightly broader than in other species.

Female

DIMENSIONS. Cephalothorax: length 1.9–2.0, width 1.5–1.7, height 0.9–1.0. Eye field: length 1.0–1.1, anterior width 1.4–1.5, posterior width 1.3–1.4. Abdomen: length 1.7–2.2, width 1.3–1.6.

COLOUR AND BODY. Similar to male, slightly lighter coloured. Anterior median eyes encircled by grey scales, grey hairs on eye field. Abdomen yellowish.

GENITALIA. Epigyne rounded, less sclerotized than in other species ( Fig. 12A–B ). Atria small, weakly sclerotized, copulatory canals long ( Fig. 12C ).
