description: Key to the taxa of the genus Proleonhardella Jeannel, 1910
(modified after Jeannel 1924) (Figs 9–10)
1. Body more elongate, elliptical. Pronotum as wide as elytra, well constricted basally. Pronotal lateral margins well-rounded backwards. Mesosternal carina very low. Elytral punctuation rough and deep (subgenus Pholeuonillus Breit, 1913). Endogean, Mt Treskavica, southern Bosnia and Herzegovina ....................................................................... P. (Pholeuonillus) adolfi (Reitter, 1911)
– Body less elongate, oval. Pronotum narrower than elytra, weakly constricted basally. Pronotal lateral margins weakly rounded backwards. Elytral punctuation fine. Mesosternal carina elevated, angled (subgenus Proleonhardella Jeannel, 1910) ....................................................................................... 2
2. Elytra shorter, more convex, less than twice as long as pronotum (Fig. 10A) ................................. 3
– Elytra longer, less convex, more than twice as long as pronotum (Fig. 10B) .................................. 6
3. Body of oval shape, longer (TL 1.8–2.2 mm). Antennae short, not reaching middle of body. Antennomere III not longer than antennomere V. Antennomere VIII globular in males (Fig. 10C).
