Drilus frontalis Schaufuss, 1867

Drilus frontalis Schaufuss, 1867: 84 .

Type material. Not available.

Type locality. Turkey, Mersin.

Diagnosis and remarks. According to the original description (Schaufuss 1867), Drilus frontalis is very similar to D. rectus . Kundrata et al. (2014b) argued that the morphological characters used for separation of those species (e.g. body size, pronotum shape and emargination of the penultimate ventrite) are variable even within D. rectus populations. Both types are probably lost and we failed to find specimens of either species from Mersin (the type locality of D. frontalis), so we retain the species status of D. frontalis until more material is available. Female and immature stages are unknown.

Distribution. Southern Turkey (Mersin Province; Fig. 55).
