Diagnosis

Carapace subreniform, surface smooth. Calcified inner lamella narrow posteriorly, wider anteriorly. Muscle scar imprints seems typical for Candoninae, although poorly visible. Antennula 4-segmented. Segments En2, En3, En4 and En5 fused. Small suture and seta En3a present between En3 and En4. Antenna in females with 4-segmented endopod, while 5-segmented in males. Male sexual bristles (t2 and t3) present. Claws G1 and G3 on male antenna reduced to setae; z1 and z2 transformed into claws, former one considerably shorter; z3 seta-like. Mandibula with 6 rays in vibratory plate. Mandibular palp 4-segmented; second segment with 1 seta externally, 3+2 setae in bunch internally; penultimate segment with 3 setae extero-distally. Terminal segment of Md-palp with broadly fused central claw; L : W of same segment equals 1.1 : 1. Maxillular palp with rectangular terminal segment, and with 6 appendages. First thoracopod with symmetrical palps, subterminal sclerified structures thin, only one well developed, another one very small and hardly visible. Second thoracopod 5-segmented, basal segment without any seta. Third thoracopod 5-segmented; basal segment with all setae present (dp, d1 and d2); setae Te and Tg present, while seta Tf missing; terminal segment with 2 long (Th2 and Th3) and 1 short seta (Th1). Caudal ramus without posterior seta, anterior setae present, both claws present and long. Hemipenis with all lobes developed. Lobe "a" with two extensions: one dorsal and one distal; dorsal much smaller than distal. Lobe "h" small and rounded; lobe "b" with one ventral, finger-like part. Part "g" very poorly sclerified. Zenker's organ with seven whorls of spines. Genital field rounded and without extensions.
