Megalothorax incertus

A single male and a moulting female were found co-occurring with M. incertus sensu nov. of the natural reserve of Zingaro (same data as sample CS. 035. IT provided for M. incertus s ensu nov.), with the following characters: 2 + 2 chaetae on the basolateral fields of labium, chaetae on the head vertex not specially thickened, a 3 present on Th. II, presence of abdominal s-chaetae s 3, 2 + 2 chaetae on Abd. IV sternite, serrated mucro, 4 + 4 teeth on the retinaculum. Integumentary channels not seen on head and trunk. The specimen is partially damaged, and no DNA data is available. Combination of characters does not fit any of the three above species. Specimens with the same features have been found in Russia, but so far we do not have sufficient data to discuss the status of the species.
