Myrmarachne aff. tristis ( Simon, 1882) View in CoL
( Figure 38A–D View Figure 38 )
Salticus tristis Simon, 1882: 212 .
Remarks
Provisional identification is based on the description of the tristis -group by Wanless (1978).
Diagnosis
Small spiders, separated from all other Sri Lankan species of the genus by the chelicerae: shorter than the prosoma, fangs with a bulbous base ( Figure 38A, B View Figure 38 ). Further, the disk-shaped male palp, with the embolus positioned on the borders of the tegulum ( Figure 38C, D View Figure 38 ) is characteristic.
Male. total length: 5.6; prosoma length: 3.2, width: 1.2. Leg I: femur 1.2, patella 0.4, tibia 1.2, metatarsus 0.6, tarsus 0.4. Prosoma oval, almost as wide as long. The cephalic part of the prosoma is elevated and sides parallel. Posterior half rounded. Prosoma laterally with dark markings ( Figure 38A, B View Figure 38 ). All eyes surrounded by dark rings. Opisthosoma oval, longer than wide, with a clear constriction in the centre of the anterior half ( Figure 38A, B View Figure 38 ). Dorsally, sclerotized, ventrally softer. Chelicerae constricted at the base, thickest at the centre ( Figure 38A, B View Figure 38 ). Male palps disk-shaped, with the embolus positioned on the borders of the tegulum ( Figure 38C, D View Figure 38 ). Chelicerae dentition not examined. Leg formula 4132. Leg spination not examined. Females have not been found from Sri Lanka.
Distribution
