Remarks
The species is similar externally to Monema flavescens, but is well distinguished by male genitalia: gnathos is narrowing and very long; juxta is long and ending in a tuft of long spines at each side. In female genitalia, base of ductus bursae of the new species is narrow and membranous, while that of Monema flavescens is sclerotized.
Etymology
The name is derived from Greek “Tanaos” (=Long) and “gnathos” (Greek for jaw), corresponding to the long gnathos in the male genitalia.
