maternum Zerny, 1931

( Fig. 16 )

Eucereon maternum Zerny, 1931b: 24 (Taf. 1, fig. 24). Holotype male [fixed by monotypy]: PERU, Madre de Dios, 1000m (Garlepp), with two labels “S. Peru, obr. Madre de Dios, 1000m ”, and “ Eucereon maternum Zerny ♂ type ”.

Current combination. Eucereon maternum Zerny, 1931 .

Condition of the type. Tips of the antennae broken. Hindlegs missing.

Remarks. This species is part of a small group of species currently placed in Eucereon , but that certainly do not belong in this genus. This group is here defined as comprising E. maternum , E. fuscoirroratum Rothschild, 1912 , E. birchelli Druce, 1901 , E. perplicatum Draudt, 1917 , E. pometinum Druce, 1894 , E. strix Rothschild, 1912 , E. velutinum Schaus, 1896 , and, possibly, E. irroratum Schaus, 1904 , E. sadana Druce, 1906 , and E. sarisa Draudt, 1917 . These species most likely do not belong in Ctenuchina , but in Phaegopterina , though the same is probably true for the core concept of Eucereon ( Travassos 1959) and though Phaegopterina itself is probably not monophyletic ( Jacobson & Weller 2002). For all these reasons a comprehensive study must be carried out to ascertain the composition of this group, and its phylogenetic placement.
