Memoan fruhstorferi comb. nov. (Pic, 1942)

Photinus fruhstorferi Pic, 1942: 16; McDermott 1966: 39

Memoan ciceroi Silveira & Mermudes, 2013: 80 syn. nov.

Remarks.

After studying Maurice Pic’s collection at the MNHN, we found that the holotype P. fruhstorferi of examined had all the diagnostic traits of Me. ciceroi (e.g., antenna with 10 antennomeres, apical antennomere subdivided, labial palp with one palpomere; Silveira and Mermudes 2013). Therefore, we propose that Me. ciceroi is a subjective junior synonym of P. fruhstorferi Pic, 1942.

Pic (1942: 16) described P. fruhstorferi as follows: " angustatus et elongatus, testaceus. Long. 6 m, Bresil , - Character par sa coloration claire jointe à sa forme élancée ". The current definition of Photinus is controversial, as pointed out by several firefly specialists (e.g., McDermott 1964), and needs taxonomic revision. In fact, P. fruhstorferi does not have characters normally found in Photinus , such as simple antennae shorter than 1/2 body length, pronotum with sides white and laterally expanded, abdominal tergites rounded, and phallobase relatively long ( McDermott 1964). Therefore, we transfer P. fruhstorferi to Memoan , generating Me. fruhstorferi (Pic, 1942) comb. nov. and synonymize it with Me. ciceroi , syn. nov., over which it has priority.
