Polana (Hobemanella) chena DeLong & Wolda 1978, comb. nov.

Polana (Hobemanella) chena DeLong & Wolda, 1978 comb. nov. Polana (Polanana) chena DeLong & Wolda, 1978: 229. Remarks. The subgenus Hobemanella is recognized mainly by the following features: (1) head as in the subgenus Polana (slightly narrower than pronotum); (2) pygofer with or without dorsal processes; when present, variable in structure; (3) aedeagus strongly curved near base, with pair of processes arising from the dorsal apodeme.According to the original description and illustrations (DeLong & Wolda 1978: 229, figs 6–10), Polana chena has the three characteristics listed above and therefore is here transferred to the subgenus Hobemanella. DeLong & Foster (1982) described six species of Polana in the subgenera Polana, Polanana and Nihilana. Polana pravida, one of the species placed in the subgenus Polana is similar to P. villara, with processes near the mid-length of the aedeagal shaft, but without processes near base. Therefore, the following combination is proposed:
