Hyposoter carbonarius insulator Aubert, 1960 : lectotype ♀, here designated, in MZLS. Label details: TYPE; ♀ ; HYPOSOTER CARBONARIUS Ratz. INSULATOR Aub. J.F.AUBERT 15.8.1959 AJACCIO ( CORSE) . Syntype 1/3 (3) Hyposoter carbonarius insulator Aubert 1960 g, labelled by S. Klopfstein 2009. GBIFCH 00832765.

This was described by Aubert (1960) as a subspecies of Hyposoter carbonarius Ratzeburg , though in Aubert (1961) he makes clear that he was uncertain whether to describe the specimens as a new species or a subspecies of carbonarius . Horstmann examined the syntype series and it is clear from his notes and his draft key that he intended to elevate the taxon to full species status. We have examined one of the syntypes (that designated as lectotype above). The type series is well distinguished from carbonarius , inter alia by the yellow tegulae and palps, the quadrate to elongate area superomedia and the partly smooth speculum and rather finely granulate mesopleuron, with no visible punctures. We therefore here raise it to species status.

The partly smooth speculum should also distinguish insulator from other species in this part of the key. The seventh tergite is not emarginate in the female, as it is in ebeninus and rhodocerae .

The biology is unknown, and the species is known only from Corsica.
