description: Identification key to the genera of Apholeuonus phyletic group
All genera of this phyletic group are found in northern, western and central Bosnia and Herzegovina. The distribution of Parapropus, Haplotropidius and Spelaites extendes to part of Croatia and southern Slovenia.
1 Pronotum approximately wide as elytra width or wider; body shape spherical or elliptical (bathyscioid, Fig. 32a) with pronotum transverse; distinctly wider than long; pronotum lateral edges not sinuate, widest at the base; small species with short legs................................................................................. Bathysciopsis Müller, 1941
- Pronotum narrower than elytra width; body shape sub-pholeuonoid (Fig. 32b), pholeuonoid (Fig 32c,d) or sub-scaphoid (Fig. 32e)with pronotum shorter or longer than wide; bigger species with prolonged legs................................. 2
2 Pronotum slightly narrower than elytra width; body shape sub-pholeuonoid; pronotum wider than long, widest at the posterior edge, lateral sides concave, straight or slightly sinuate....................................................... 11
- Pronotum distinctly narrower than elytra width; body shape pholeuonoid or sub-scaphoid, pronotum distinctly longer than wide, widest at the middle length, lateral sides strongly or slightly sinuate........................................ 3
3 Body shape prolonged sub-scaphoid; pronotum distinctly narrower than half elytra width; mesocoxal cavities confluent; antennae longer than body........................................................... Parapropus Ganglbauer, 1899
- Body shape pholeuonoid; pronotum equally wide or wider than half elytra width; mesocoxal cavities separated by extension of mesoventrite......................................................................................... 4
4 Robust species, body length more than 4.5 mm; second antennomere length sub-equal to third antennomere............. 5
- Slender species, body length less than 4.5 mm; second antennomere distinctly longer than third antennomere............ 7
5 Pronotum approximately wide as head width; prolonged slender body; elytra prolonged; pronotum distinctly longer than wide with sinuate lateral edges; mesosternal keel greatly reduced.................................................... 6
- Pronotum distinctly wider as head width; elytra strongly inflated with surface almost glabrous and with shining effect; pronotum slightly longer than wide; first antennomere two times shorter than second antennomere; mesosternal keel reduced to strong dent..................................................................... Apholeuonus Reitter, 1889
6 First antennomere distinctly shorter but not two times shorter than second antennomere; mesosternal keel strongly reduced, almost atrophied.................................................................. Spelaites Apfelbeck, 1907
- First antennomere two times shorter than second antennomere; mesosternal keel reduced to strong wide dent....................................................................................... Protobracharthron Reitter 1889
7 Pronotum approximately wide as head width; mesosternal cavities separated with an extension of mesoventrite without a keel................................................................................ Antrosedes Reitter, 1912
- Pronotum distinctly wider as head width; mesosternal cavities separated with an extension of mesoventrite with well-developed keel................................................................................................ 9
9 Elytra surface shining, and with sparse long and erected setae................................... Setnikia Breit, 1913

- Elytra strongly, sparsely and deeply faveolated punctate, almost glabrous or cowered with short sparse erected setae; each seta growing from the bottom of a small depressed point; femora distinctly widened at apex; male protarsomeres not dilated... 12
12 Elytra almost glabrous with shining effect; globular body shape with pronotum distinctly wider than its length............................................................................................. Icharonia Reitter, 1912

13 Body length bigger 3.0— 3.5 mm; first antennomere two times shorter than second one; short and pointed spines forming a coarse comb in externo-lateral edge of protibia stretching from apex to the middle of tibia length; suture between mesosternum and mesepisternum almost entire, not atrophied on its anterior side; mesosternal keel elevated, strongly dentate and not straight on its ventral edge; mesothoracic apophysis short and distinctly wider than long; metatergal apparatus reduced, but with long and narrow posterior process...................................................... Charonites Apfelbeck, 1907
- Body length smaller 2.3—2.5 mm; first antennomere distinctly shorter but not two times shorter than second one; flattened short almost triangular spines forming a dense comb in externo-lateral edge of protibia stretching from apex to the end of second third of tibia length; suture between mesosetrnum and mesepisternum partly atrophied on its anterior side; mesosternal keel elevated and straight on its ventral edge; mesothoracic apophysis short and narrow equally wide as long, metatergal apparatus strongly reduced, almost without posterior process..........................................
