Polana (Nihilana) pravida DeLong & Foster 1982, comb. nov.

Polana (Nihilana) pravida DeLong & Foster, 1982 comb. nov. Polana (Polana) pravida DeLong & Foster, 1982: 324. Remarks. The median processes of the aedeagal shaft were originally described as follows: “A long slender process arises each side near middle of shaft and extends to the apex”. Therefore P. pravida lacks processes at the base of the aedeagus. Following the key to subgenera provided by DeLong & Freytag (1972), this species cannot be placed in the subgenus Polana. DeLong & Wolda (1982) described five species of Polana, placing them in the subgenera Nihilana, Polana, and Polanana. However, the three species placed in the subgenus Polana, P. tinae, P. divesita, and P. julna lack processes on the pygofer and base of aedeagus, as shown in the descriptions and illustrations provided. Therefore, the three species are transferred to the subgenus Polanana:
