Moldovan, Oana Teodora, Racoviţă, Gheorghe & Dunay, Gejza, 2007, Reconsidering Pholeuon C. Hampe (Coleoptera: Leiodidae: Cholevinae), with the description of a new subgenus, Zootaxa 1449, pp. 31-43 : 38-39

Key to subgenera of Pholeuon (numbers represent average values for the two sexes; see also Table 1 )

1 Median lobe of the aedeagus without dorsal invagination ( Fig. 8 a). Small body (length 3.6–3.8 mm) and small pronotum (length/maximum width ratio 0.91–0.93 mm); ellongated elytra........................................ ........................................................................................................................ Protopholeuon Jeannel, 1923

- Median lobe of the aedeagus with dorsal invagination .................................. Pholeuon C. Hampe 1856 ... 2

2 Dorsal invagination of the median lobe present, more or less deep ........................................................... 3

- Dorsal invagination of the median lobe reduced in its median part ( Fig. 8 b); aedeagus small, but with relatively long basal and apical blades; apex of the parameres thin and slightly inflected. Body small (less than 3.5 mm), with short antennae (less than 2.3 mm); pronotum relatively large (length/maximum width ratio 0.93–0.95 mm), very narrow anteriorly (anterior/maximum widths ratio 0.55–0.56 mm); elytra covered by short and dense pubescence ............................................................................................................. ................................................... Pholeuon (Mesopholeuon Moldovan, Racoviţă & Dunay, new subgenus)

3 Median lobe with deeper dorsal invagination ( Figs. 8 , c-d); apex of parameres thin, inflected and Sshaped. Body robust (length more than 4.3 mm); pronotum relatively large (length/maximum width ratio 0.94–0.98 mm); elytra longer than 3.1 mm, with rare and rough punctation at the apex .. Pholeuon (s. str.)

- Median lobe with less deep invagination ( Fig. 8 e); apex of parameres clubed and not inflected. Body smaller (less than 4.3 mm); pronotum relatively small (length/maximum width ratio 0.86–0.89 mm); elytra narrow (1.75–1.77 mm width) with uniform punctation; very long antennae .................................... ................................................................................................
