Thriniulus Chamberlin, 1940:21 . Loomis, 1968a:76. Jeekel, 1971:178. Hoffman, 1980:108; 1999:165.

Type species. Paraiulus leucoclius Chamberlin, 1922, by original designation.

Diagnosis. Coxal process of anterior gonopods tapering slightly distad but broad throughout length, obscuring apices of telopodites in anterior view; telopodites leaning strongly mediad. Posterior gonopod with anterior branch narrowing abruptly at midlength and continuing into long, curvilinear prolongation overlying caudal branches; solenomere with narrow, curvilinear subbranch arising from caudal margin, overlying breadth of structure and extending anteriomediad beyond level of lamellate, spinulate expansion.

Component species. One

Distribution. Known only from the type locality of the lone component.

Remarks. Nothing remotely resembling T. leucoclius is currently known in the Parajulini, so at present, Thriniulus is regarded as a monotypic genus.
