Diagnosis

A species of Geotypodon gen. nov. in which the gonopod coxal metaplica is produced mesad in a thin lamella, a small longitudinal lamella, perpendicular to the other, is present on the anterior part of the metaplica, the telomere is apically divided into two lobes of approximately equal size, and the limbus lobes are multi-cusped, hand-like. Shares these characters with G. millemanus gen. et sp. nov., but differs from that species in smaller size, bicuspid mesal margin of metaplical lamella and presence of a spine-like process on the posterior apical telomeral lobe.

Etymology

The name is a Latin adjective referring to the habitat.
