Chelicerae Description: “No distinct mesal tooth on movable cheliceral finger, fondal teeth graded in size I,II, III, IV for both rows, and two denticles in fondal notch; ECCS shown at 140x” (Muma, 1989, p. 22).


Palpal Description: “An elongate scopula of 30-40 papillae in palpal metatarsus which is 3 times length of tarsus” (Muma, 1989, p. 22).


Operculum Description: “Opercular structure is most similar to iviei and malkini” (Muma, 1989, p. 23).


Diagnosis: “Species distinguished from iviei by longer scopula on palpal metatarsus with a greater number of papillae (30-40 as opposed to 20-30), and only palpal tarsus and metatarsal tip dusky; distinguished from medialis by presence of scopula and 6 abdominal ctenidia and reduced dusky markings on palpal metatarsi” (Muma, 1989, p. 22).
