Stilbum calens westermanni Dahlbom, 1845

Stilbum westermanni Dahlbom, 1845: 16 . Holotype ♂; Greece: Rhodes Is. (NHRS).

Stilbum calens ab. subcalens Mader, 1933: 126. Type series unknown; Croatia: Dalmatia, Krk Is. (Vienna). Unavailable name (ICZN 1999: Article 45.6.2).

Stilbum calens var. subcalens Linsenmaier, 1951: 107 . Based on the description of Stilbum calens ab. subcalens Mader, 1933.

Stilbum calens subcalens: Linsenmaier 1968: 123 ( Lebanon, without locality).

Material examined. N. Lebanon: Kadisha Grotto , 1670 m, 21.vi.1960, 2♂, leg. G.A. Mavromoustakis, Stilbum calens wesmaeli det. Linsenmaier ( NMLU) .

Distribution. Lebanon. From Mediterranean countries to Iran ( Linsenmaier 1968).

Remarks. Linsenmaier (1951, 1959, 1968) treated the unavailable name Stilbum calens ab. subcalens ( Mader, 1933) as subspecies of Stilbum calens , and thus made this name available as species-group name (ICZN 1999, article 45.6.3). As Linsenmaier was the first author to make the name available, he became the author of Stilbum calens subcalens (ICZN 1999, article 50.3.1.). Later Linsenmaier (1997, 1999) identified the same taxon as Stilbum calens wesmaeli Dahlbom, 1845 without type examination and without any discussion. After type examination, Rosa & Vårdal (2015) observed that Stilbum wesmaeli is closely related to Stilbum cyanurum and not to Stilbum calens as supposed by Linsenmaier (1997: 287). The first available name for this taxon is therefore Stilbum calens westermanni Dahlbom, 1845 (= Stilbum calens subcalens Linsenmaier, 1959 ) ( Rosa & Vårdal 2015), the subspecific name which was ignored by Linsenmaier (1959, 1968, 1997, 1999).
