Salticus bicurvatus O. Pickard-Cambridge, 1869: 67 , plate 6, figures 57–60. Myrmarachne bicrivata: Sherriffs, 1931: 539 (lapsus).

Type material

Holotype of Salticus bicurvatus : male from Sri Lanka ( OUMNH 1735.2 ), no more data given, examined. Pickard-Cambridge (1869) says that the single specimen in OUMNH was captured in Sri Lanka by Mr G.H.K. Thwaits. Exact locality unknown.

Diagnosis

Very similar to M. ramunni ; however, males are separated by the shape of the male chelicerae: with chelicerae in dorsal view, outer margins of chelicerae are weakly convex in M. bicurvata , but distinctly convex in M. ramunni ( Figure 2A, B View Figure 2 ). The RTA of the male palp in M. bicurvata is apically hooked and strongly curved at the base ( Figure 3B–D View Figure 3 ).

Description

Male from Lahugala: total length: 5.6; prosoma length: 3.6, width: 1.2. Leg I: femur 1.6, patella 0.4, tibia 1.2, metatarsus 0.8, tarsus 0.4. The cephalic part of the prosoma is elevated and rounded on all sides. The thoracic part is lower than the cephalic, the highest point being the centre ( Figure 2A–D View Figure 2 ). Opisthosoma oval, slightly longer than wide, with no clear constriction ( Figure 2A–D View Figure 2 ). Opisthosoma dorsally sclerotized, venter softer. Chelicerae are almost the length of the carapace, lateral sides almost parallel; distal half is a bit wider than the proximal half ( Figure 2A–D View Figure 2 ). Chelicerae dentition not examined. Leg formula 4132. Leg spination not examined. Palps as in Figure 3A–D View Figure 3 . Female remains unknown.

Distribution

Known only from Sri Lanka.
