Diagnosis

Female

empodia I-IV = short, strongly curved claw, shorter than proximoventral hairs; lower proximoventral hair significantly longer and thicker than others (Figs 1-3)
pregenital striae entirely longitudinal
dorsal setae set on tubercles (Fig. 4)
peritreme ending in small rounded expansion (Figs 5, 6)
lobes on dorsal striae small, triangular, closely spaced (Fig. 7; see also Fig. 15) 
dorsal setae strongly but finely barbed
dorsal setae f1 much longer than h1 & f2 (Fig. 8)
dorsal setae h1 and f2 subequal in length (Fig. 8)
tarsus I with the sockets of three tactile setae and one solenidion proximal to, and two tactile setae overlapping, the socket of the proximal duplex seta
tarsus II with the sockets of two tactile setae and one solenidion proximal to, and two tactile setae overlapping, the socket of the duplex seta

Male (Fig. 9) as per female plus:

• empodia I-IV as in female (Figs 10-12)
• empodium I with lower proximoventral hair strong, shortened and thickened (Figs 10, 11)
• peritreme ending in a simple bulb (Figs 13, 14)
• dorsal cuticle with minute lobes, closely spaced; cuticle with spiculate appearance (Fig. 15)
• dorsal setae f1 much longer than h1 & f2, as in female (Fig. 16)
• dorsal setae h1 & f2 subequal in length, as in female (Fig. 16)
• tarsus I with the sockets of three tactile setae and three solenidia proximal to the socket of the proximal duplex seta
• tarsus II with the sockets of two/three tactile setae and two solenidia proximal to the socket of the duplex seta
• aedeagus dorsally directed, finely tapered with no anterior or posterior projections; shaft abruptly tapering to form dorsal projection; dorsal margin of shaft at 45° angle to ventral margin, broadly curving dorsally at 60-70° angle, then tip curving posteriorly at 45° angle; dorsal projection elongate, finely tapered towards tip (Figs 17-20)
