description: Key to the species of the subgenus Paralister Bickhardt, 1917 of the genus Margarinotus Marseul, 1853 from the Balkans
1. Elytral epipleuron impunctate or only with scattered microscopic punctures; elytra in most cases with red maculae; occasionally entirely reddish-brown (Fig. 5)........................... Margarinotus (Paralister) purpurascens (Herbst, 1792)
1’. Elytral epipleuron always with dense punctures; elytra always entirely black, without red maculae (Fig. 1)............... 2
2. Lateral pronotal stria distanced from lateral pronotal margin, straight, often stopping short of pronotal base (Fig. 6); body outline short, rounded..................................... Margarinotus (Paralister) ventralis (Marseul, 1854) (Fig. 7)
2’. Lateral pronotal stria always slightly sinuate (Fig. 8), never straight, not particularly distanced from the lateral pronotal margin; body outline usually more elongate................................................................... 3
3. Marginal prosternal stria not attaining suture between prosternal keel and lobe (Fig. 9)............................... 4
3’. Marginal pronotal stria attains suture between prosternal lobe and keel (Fig. 12)................................... 5
4. Apical pronotal angles with distinct punctures (Fig. 10); smaller species, PEL: 4.50–6.00 mm.............................................................................. Margarinotus (Paralister) ignobilis (Marseul, 1854) (Fig. 11)
4’. Apical pronotal angles impunctate; large species, PEL: 8.00 mm. Margarinotus (Paralister) longus (Bickhardt, 1910) (Fig. 1)
5. Prosternal keel with distinct carinal prosternal striae (Fig. 13); punctures of pygidium large and dense, separated by less than their diameter (Fig. 14)............................. Margarinotus (Paralister) punctiventer (Marseul, 1854) (Fig. 15)
5’. Prosternal keel without carinal prosternal striae (Fig. 12), at most these are faintly impressed between procoxae; punctures of pygidium not so dense, separated by their own to several times their diameters (Fig. 17)............................. 6
6. Shortly oval, round species, PEL usually shorter than 4.50 mm; 4th dorsal elytral stria usually not reaching ¾ elytral length basally; aedeagus with large basal piece (Fig. 18); median lobe and armature (Fig. 19).................................................................................. Margarinotus (Paralister) carbonarius (Illiger, 1798) (Fig. 16)
6’. Oval, elongate species, PEL usually larger than 4.50 mm; 4th dorsal elytral stria usually surpassing ¾ of elytral length basally, occasionally almost complete; aedeagus with smaller basal piece (Fig. 21); median lobe and armature (Fig. 22)............................................................... Margarinotus (Paralister) neglectus (Germar, 1813) (Fig. 20)
