Neofedrizzia Womersley 1959

Neofedrizzia Womersley, 1959: 30 . Type species: Neofedrizzia gayi Womersley, 1959 , by original designation.

Diagnosis. Both sexes: dorsal shield without large pores; with separate ventral and ventrianal shield; CxIVmarginal suture present ( Fig. 40 ); lateral setae on ventrianal shield small, <15 long; exopodal region heavily sclerotised ( Figs 39–40 ) or with striped pattern ( Figs 37–38 ); pores laterad CxIV usually clustered; seta pv1 on femur III–IV spine-like ( Fig. 8 ); femur III–IV with lamellae ( Figs 7–8 ); femur IV not elongated; spur on palp trochanter without accessory spine; seta av1 on palp trochanter barbed ( Fig. 4 ); seta h1 branched or barbed, curved inwards ( Figs 4 , 32 ); corniculi usually not on hypostomal tubercles ( Fig. 4 b); one non-filamentous excrescence often modified into a short barb-like process ( Fig. 43 ). Female: pore stp x anterior of stp2; sternogynial shield generally semi-ovular, evenly rounded posteriorly, usually with slight inward curve anteriorly ( Figs 2 b, 3b). Male: often without tetartosternum bearing st1 ( Fig. 13 c), if absent, then often with small presternal processes ( Figs 13 d–f, 14); base of tritosternum much broader than female; anterior valve of genital opening subequal to posterior valve ( Fig 21 b), often flanked by several pores; CxI larger than female CxI.
