locality of some of the
types
; noun in apposition.
Diagnosis.
Females of

resemble those of

(

) by the vulva with internal ducts with FW postero-laterad, GP posteriad and spermathecae ovoid. They are distinguished from the latter species by the epigyne with MS narrow, three times longer than wide, widest posteriorly and EP with anterior margin reaching one fifth MS length (MS roughly two times longer than wide, widest medially and EP with anterior margin reaching half MS lenght in
M. jaraua
spec. nov.
). Males are unknown.
