Equestrigonus gen. n.

Diagnosis.

Like Amastigogonus and Victoriocambala Verhoeff, 1944 in having greatly reduced posterior gonopods with a single lateral process, and relatively simple, two-branched anterior gonopods with the prostatic groove entering a pseudoflagellum on the telopodite. Distinguished from the other two genera by the form of the anterior gonopods (Figs 11A, 13A): coxite process a bluntly pointed rod, longer than telopodite; telopodite slender with a distal, spreading crown of setae. Distinguished from all other Tasmanian Iulomorphidae by the posteroventral extension of the cardo (Fig. 12B; ce) in males.

Type species.

Equestrigonus tasmaniensis sp. n., by present designation.

Name.

From Latin equestris, genitive singular of equester, pertaining to horse-riding, plus -gonus, a suffix commonly used in millipede names, referring to the gonopods; masculine gender. The tips of the anterior gonopod of the type species (Fig. 11A) resemble the ends of prick and rowel spurs.
