Etymology. The specific name honors Dr. David Kavanaugh (CAS), who collected the type specimens, and is a name in genitive case.

Diagnosis. This species is similar to Lysiteles himalayensis Ono, 1979 , but can be separated from the latter by its blackish brown carapace (yellowish brown in L. himalayensis ), presence of stripes on opisthosoma dorsum (absent in L. himalayensis ), copulatory ducts thick (thin in L. himalayensis ) and spermathecae pearshaped (globular in L. himalayensis ).

Description. Female (holotype): Total length 3.20. Prosoma 1.50 long; 1.30 wide; opisthosoma 2.00 long, 1.80 wide. Carapace blackish brown, with several long bent setae. Both anterior and posterior eye rows recurved. Eye tubercles blackish brown with white rim. ALE tubercles largest. Eye sizes and interdistances: ALE 0.20, PLE 0.15, AME 0.08, PME 0.05, AME-AME 0.19, AME-ALE 0.20, PME-PME 0.25, PME-PLE 0.30; MOA long 0.30, front width 0.35, back width 0.38. Clypeus height 0.25. Sternum cordiform, light gray, darker along margins. Chelicerae, labium blackish brown, gnathocoxae yellowish brown. Legs light yellowish brown. Leg measurements: I 3.70 (1.20, 1.30, 0.70, 0.50), II 4.20 (1.40, 1.50, 0.70, 0.60), III 2.70 (1.00, 0.80, 0.40, 0.50), IV 3.00 (1.00, 1.00, 0.50, 0.50); formula 2, 1, 4, 3. Spination: Femora: I prolateral 1-1-1, I, IV dorsal 0-1-0, II dorsal 1-1-0, III dorsal 1-1-1; Patellae: I-IV 1(weak)-1; Tibiae: I-IV dorsal 1-0-1, retrolateral 0-1- 1, I-II prolateral 1-1-1, ventral 2-2-0, III-IV prolateral 1-1, III ventral 2, IV 1; metatarsi I-IV pro-, and retrolateral 1-1, ventral 2-2, III-IV ventral 2. Opisthosoma subcircular, dorsum yellow, the anterior lightly yellowish brown with yellowish brown claviform stripes on the margin and black claviform stripes on the side. The median with scattered small black and white spots. Venter yellow with small white spots, mesally with a longitudinal black stripe.
