On Apeba Martins & Galileo, 1991 and LycidolaThomson, 1864
Thomson (1864) created Lycidola for Lycidola palliata ( Klug, 1825 ) . According to Thomson (1864) , Lycidola were defined as follows (translated): “Antennae shorter than body; antennomere III very long, antennomeres 3–4 widened; elytra enlarged; legs moderate.” Thomson (1868) added L. togata ( Klug, 1825 ) to the genus. Later, the following species were described and also added to the genus: L. simulatrix Bates, 1866 , L. beltii Bates, 1872 , L. felixWaterhouse, 1880 , L. flavofasciataWaterhouse, 1880 , L. retiferaWaterhouse, 1880 , L. expansa Bates, 1881 , L. unicolor Bates, 1885 , L. isabellina Bates, 1885 , L. eximia Bates, 1885 , L. laevipennis Gahan, 1892 , L. batesiAurivillius, 1923 , and L. palliata ab. nigrohumeralisTippmann, 1960 . According to Bates (1881a) , “Nine species of this very remarkable genus are known, all, with the exception of the one recorded below [ L. beltii ], South- American.” Bates (1881b) subsequently listed the following 10 species to Lycidola : L. palliata ; L. togata , L. simulatrix , L. beltii , L. flavofasciata , L. felix , L. retifera , L. expansa , L. mimica (Bates, 1866) , and L. capillacea (Bates, 1881) .
Martins & Galileo (1991a) divided Lycidola into six genera, with five of them ( Acabanga , Tetamauara , Icupima , Iarucanga and Apeba ), newly described. Lycidola and Apeba were separated in the alternative of couplets “5” (translated): “Each elytron with 4 carinae… Lycidola / Each elytron with 2 carinae…… Apeba .” They included L. palliata (type species), L. batesi , L. beltii , L. expansa , L. felix , L. flavofasciata , and L. simulatrix in Lycidola , and also moving L. togata (type species), L. antiquaWaterhouse, 1880 (transferred from LycaneptiaThomson, 1868 ), L. isabellina , and L. barauna to Apeba . Latter, Galileo & Martins (2006) described Lycidola popeba , and Martins & Galileo (2012) described L. affinis .
According to Martins & Galileo (1991a) , the prosternal process in Lycidola is as wide as a procoxa, and in Apeba 1/3 the width of a procoxa. Evidently, they were talking about the central area of the prosternal process. However, the prosternal process in Lycidola , although usually wider than in Apeba , is never as wide as a procoxa ( Figs 2, 4, 6, 8 ), and sometimes is slightly wider ( Fig. 4 ) than in Apeba ( Figs 10, 12, 14 ). Thus, this feature cannot be used as a differential character.
We propose to redefine Lycidola as having four carinae on each elytron ( Figs 1, 3, 5 7 ), with the second and third (from suture to outer side) fused at apical third (Y-shaped). Apeba is then comprised of species with just two or three elytral carinae ( Figs 9, 11, 13 ) and none fused.
