Note. This species was described based on three males and two females collected in Nuwara Eliya , Sri Lanka, but one of the female syntypes was not congeneric with the remaining specimens. We describe this specimen as Devendra amaiti sp. nov.

Diagnosis. Males of D. seriatus can be diagnosed from other male Devendra by having the palpal tibia with the RTA median, short and unarmed ( Fig. 12A, B ), the embolus cylindrical ( Fig. 12A, C ) and the median apophysis not extending proximad of its joint with the tegulum ( Fig. 12A ). Females of D. seriatus can be diagnosed from other female Devendra by having the epigynum with the median lobe truncate posteriorly ( Fig. 12D ), vulva with the head of the spermathecae arising from elongate tubercles on main body of spermathecae and the opening to copulatory ducts narrow ( Fig. 12E, F ).

DesCription. Male (lectotype): Total length 5.00. Markings typical for the genus. Carapace 2.62 long, 1.87 wide, 0.85 high; clypeus 0.08 high. Eye diameters: AME 0.06, ALE 0.10, PME 0.11, PLE 0.11. Chelicerae 0.92 long; sternum 1.24 long, 1.05 wide; labium 0.44 long; palpal coxae 1.00 long. Spination as in genus description. Leg measurements (Femur + Patella + Tibia + Metatarsus + Tarsus = [Total]): I: 2.10 + 0.82 + 1.83 + 1.75 + 1.50 = 8.00; II: 1.75 + 0.75 + 1.45 + 1.50 + 1.15 = 6.60; III: 1.66 + 0.70 + 1.25 + 1.85 + 1.00 = 6.46; IV: 2.15 + 0.90 + 1.75 + 2.60 + 1.40 = 8.80. Leg formula 4123. Palp: tibia with almost the same length of cymbium, RTA positioned close to the middle of tibia, with tapered apex ( Fig. 12A, B ); cymbium tapering gradually to base; oval tegulum ( Fig. 12A ); MA origin central, with prolateral basal projection ( Fig. 12A ); short, hyaline conductor ( Fig. 12A ); embolus convex, unmodified, gradually tapering to pointed apex ( Fig. 12A–C ).

Female (paralectotype): Total length 6.15. Markings typical for the genus. Carapace 3.10 long, 2.10 wide, 1.10 high; clypeus 0.10 high. Eye diameters: AME 0.08, ALE 0.12, PME 0.12, PLE 0.13. Chelicerae 1.35 long; sternum 1.32 long, 1.16 wide; labium 0.55 long, palpal coxae 1.20 long. Spination as in genus description. Leg measurements (Femur + Patella + Tibia + Metatarsus + Tarsus = [Total]): I: 2.10 + 0.90 + 1.75 + 1.60 + 1.25 = 7.60; II: 1.90 + 0.90 + 1.40 + 1.50 + 1.10 = 6.80; III: 1.80 + 0.75 + 1.25 + 1.70 + 1.10 = 6.60; IV: 2.25 + 0.90 + 1.80 + 2.70 + 1.50 = 9.15. Leg formula 4123. Epigynum: oval epigynal plate; curved fold dividing median lobe and lateral lobes ( Fig. 12D ). Spermathecae rounded with apical projection with glandular opening ( Fig. 12F ). Material examined. Only the types.

Variation. Male (N= 3): total length 4.65–5.35; carapace length 2.60–2.75; femur I 1.90–2.15. Distribution. Known only from the type locality at Nuwara Eliya in Sri Lanka ( Fig. 14 ).
