Diagnosis. As for the family, see above.

Description. Species with 39+t trunk rings in adult males.

Head, gnathochilarium and antennae typical of order. Antennae with accessory sensillae on antennomere six ( Fig 3 View FIGURES 2 – 7 ).

Collum ( Fig 2 View FIGURES 2 – 7 ) with short, roughly triangular paranota. Trunk rings with prominent paranota ( Figs 4–7 View FIGURES 2 – 7 ), nearly horizontal, angular; metazonites appearing broadly rectangular.

Epiproct not concealed by penultimate ring, with two spinnerets; epiproct process with deep indentation between spinnerets ( Fig 11 View FIGURE 11 ). Paraprocts obliquely divided into small dorsal and larger ventral sclerite, with many scattered setae.

Dorsal surfaces of trunk rings finely setose, with scattered longer setae.

Spiracles displaced anteriorly, greatly reduced.

Gonopods ( Figs 16 View FIGURES 14 – 16 , 18–20 View FIGURES 17, 18 View FIGURES 19 – 22 ) with complete sternum, coxae protruding from aperture, basally constricted by aperture; coxa with flagellum; flagellum distally with multiple hastate teeth; telopodite reduced, with few setae, distal acuminate process, not divided into prefemur and acropodite, not modified to sheath coxal flagellum.
