Issus frontalis Fieber, 1876

Issus frontalis Fieber, 1876: 264 , [separata 1876: 254] Issus novaki Dlabola 1959: 152 , syn. n.

Issus truncatus sensu Holzinger, Kammerlander & Nickel 2003: 451 , fig. 247. (Fig. 2)

Type material examined. 3, lectotype (here designated) ( MNHN (EH)7476), with hand-written label: “Görz” (NLC); 3, paralectotype ( MNHN (EH)7477), with Noualhier’s hand-written label: “ Type Fieber” (NLC).

Note. Fieber mentioned Italy, Southern France, and Tyrol as type localities for the species. According to Fieber’s manuscript he studied at least a male and a female. Two males from NLC correspond to Fieber’s drawings (male genitalia are figured). The male from Görz ( Austria, Tyrol) is here designated as the lectotype and another male without geographical label is here recognised as a paralectotype. Apparently the last male was figured by Fieber, because it has genitalic complex exposed and accordingly this male is from Croatia as written on the drawing. We prefer to designate the specimen from Görz as the lectotype because Tyrol was mentioned as one of the type localities while Croatia was not. In NLC and PC there are also females in a row “ Issus frontalis ”, but their taxonomic position is unclear, because identification is only possible for males. These may be the female specimens mentioned by Fieber (1876) in his original description of the species and, if so, are paralectotypes.

The synonymy of I. frontalis and I. muscaeformis proposed by Löw (1883) and supported by Holzinger, Kammerlander & Nickel (2003) is incorrect.
