Athukorala, litter. 1♀ (IFS _ Oon _142): Sri Lanka: Badulla District, Bandarawela, 06°50ʹ59.5ʺN 81°00ʹ48.1ʺE, 1042 m, 31 December 2011, S. P. Benjamin et al., litter. Deposited in ZFMK.   
 Diagnosis   
Males can be identified by the narrowed, elongated bulb, without tiny conical projection, the slightly curved embolus with a bifid end and a conductor (Figure 2 (b)). Females are recognized by a relatively short anterior receptaculum (Figure 2 (c)).  
 Description   
 Male. Body length: 1.72. Cephalothorax as in Figure 1 (a), pars cephalica strongly elevated, surface of elevated portion of pars cephalica smooth sides smooth. Eyes (Figure 1 (a)), all eyes subequal, circular, ALE-ALE and PME-PME touching, ALE-PLE separated by less than their radius. Sternum longer than wide (Figure 1 (c)), without radial furrows between coxae I–II, II–III, III–IV, surface smooth, with small hairs and few small pits, continuous margin (see arrow in Figure 1 (c)), anterior margin concave, posterior margin extending posteriorly of coxae IV, distance between coxae I–II, II–III, III–IV approximately equal.   
Abdomen as in Figure 1 (e). Dorsal scutum sclerotized, pale orange, without colour pattern, covering about 3/4 of abdomen (Figure 1 (e)), more than 1/2 to most of abdomen width, not fused to epigastric scutum. Postepigastric scutum sclerotized, pale orange, almost rectangular, covering about 1/2 of abdominal length, fused to epigastric scutum. Two brown patches located above the spinnerets. Legs strong spines on leg I and II present, leg I: femur, pv0–0–1–1–1; tibia, v2–2–2–2–2–0; metatarsus, v2–2–0; leg II: femur, pv0–0–0–1–1, tibia, v2–2–2–2–2–0, metatarsus, v2–2–0, claw like setae present on leg III and IV.  
Genitalia. Sperm pore large, circular, situated at level of anterior spiracles. Palp not strongly sclerotized, femur more than two times longer than patella, three trichobothria on tibia. Cymbium pale orange, completely fused with bulb, no seam visible, with distal patch of setae, distal part without tiny conical projection (Figure 2 (a)). Bulb narrowed, elongated (Figure 2 (a)). Embolus slightly curved with a conductor which is shorter than (3/4 of) the embolus (Figure 2 (a), 2(b)).  
 Female. Body length: 2.04. As in male except as noted. Female palpal claws and spines absent, tarsus smooth. Abdomen ovoid, posterior spiracles connected by groove. Dorsal scutum covering 3/4 of abdomen (Figure 1 (f)). Postepigastric scutum only around epigastric furrow, not fused to epigastric scutum.   
Genitalia. Ventral view: anterior margin of postepigastric scutum with a thin, procurved sclerotized ridge (see arrow in Figure 1 (g)). Dorsal view: short anterior receptaculum, with a narrow lumen, without bracket-shaped semicircular sclerotized ridges, apparently without posterior receptaculum (Figure 2 (c)).  
 Etymology   
The specific name is taken from the type locality.  
 Distribution   
Koslanda, Beragala, Namunukula and Bandarawela (Figure 11).
