description: Myrmarachne paludosa (Simon, 1900) comb. nov.   
(Figures 13A, B, 14A–G, 15A–H, 16A–D)   Panachraesta paludosa Simon, 1900: 405    Type material   
 Syntypes of Panachraesta paludosa: 6 females and 4 juveniles, Sri Lanka, Colombo, no more data given (MNHN 20511/2306). Examined.    Diagnosis   
 Myrmarachne paludosa (Simon, 1900) comb. nov. could be separated from other Sri Lankan Myrmarachne species by the shape of the chelicerae: proximal half of chelicerae not constricted, outer sides more or less parallel, curved dorsum. Further, the black coloured body covered with fine white hairs (Figures 14A–G, 15A, B) and the upward pointing, tapering RTA is diagnostic. Females may be separated by the elongated S that partly surrounds CO, connecting to it at the bottom margins (Figure 15E–H).    Description   
Male from Thawalamtenne: total length: 8.0; prosoma length: 5.6, width: 1.6. Leg I: femur 1.6, patella 0.7, tibia 1.6, metatarsus 0.8, tarsus 0.5. Prosoma oval, somewhat longer than wide. Opisthosoma oval, longer than wide. Uniformly black coloured, preserved specimens dark reddish brown. Legs a light reddish brown with black rings. All eyes surrounded by dark rings. Leg formula 4132. Leg spination not examined. Palps as in Figure 16A–D. Female: total length: 5.6; prosoma length: 1.6, width: 1.4. Leg 1: femur 1.6, patella 0.8, tibia 1.6, metatarsus 0.8 tarsus 0.4. Morphology as above, except for the lighter coloured prosoma and opisthosoma. Leg formula 4132. Leg spination not examined. Epigynum and vulva as in Figures 13B, 15E–H. S elongated and partly surrounds CO, connecting to it at the bottom margins (Figure 15E–H).   Distribution   
Known only from Sri Lanka. Probably endemic as it occurs only in primary forest of the wet zone and is absent in the surrounding dry forest and coastal regions.   Natural history   
 The specimen from Gilimale was collected together with ants of the genus Camponotus. However they are different to the Camponotus species associated with M. prava.    Other material examined
