Identification
Types have not been examined. Narayan (1915) illustrates and describes the unique chelicerae of this species, aiding positive identification.
Material examined
Sri Lanka, Eastern Province, 1 male, Ampara District, Inginiagala, 250 ff, Samudra gardens, 22–23 November 1976, G.F. Havel, R.E. Dietz IV, S. Karunaratne, USNM .
Diagnosis
Very similar to M. bicurvata , however, males are easily separated by the chelicerae. The distal half of the chelicerae of M. ramunni is wider than the proximal half ( Figure 2E View Figure 2 ). The inner and outer sides of the proximal half are parallel, whereas the distal half has convex outer sides and parallel inner sides. M. bicurvata has parallel inner and outer sides ( Figure 2A, C View Figure 2 ). The RTA of the male palp is broad base and tapered to a point in one corner. In M. bicurvata the RTA is hook-shaped with a constriction at the base ( Figure 3B, E View Figure 3 ).
Description
Male: total length: 6.8; prosoma length: 4.4, width: 1.2. Leg I: femur 1.6, patella 0.6, tibia 1.6, 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 2E, F View Figure 2 ). Opisthosoma oval, almost as wide as long, with no clear constriction ( Figure 2E, F View Figure 2 ). Dorsally sclerotized, ventrally softer. Chelicerae are characteristically long and stout, distal half is wider than the proximal half ( Figure 2E, F View Figure 2 ). The distal half is hammer-shaped. The inner and outer sides of the proximal half are parallel, whereas the distal half has convex outer sides and parallel inner sides. Chelicerae dentition not examined. Leg formula 4132. Leg spination not examined. Palps as in Figure 3E, F View Figure 3 . Female: remains unknown, but see Dyal (1935) for a description of a female attributed to this species.
Natural history
Borges et al. (2007) associated the ant Myrmicaria brunnea with this species (spiders identified as Myrmarachne morphospecies 3).
Distribution
India, Pakistan, Sri Lanka.
