ʻ Glischrochilus ʼ janthinus ( Reitter, 1877)

Ips janthinus Reitter, 1877: 130 (original description; Tasmania).

Glischrochilus (?) janthinus: MILLER & WILLIAMS (1981) : 5 (new combination).

Comments to classification. Ips janthinus Reitter, 1877 was described from Tasmania by REITTER (1877). As for the depository of types he wrote ‘In meiner Sammlung. Soll sich unter obigem Namen in Berliner Museum befinden’ [= In my collection. Should be under the above name in the Berlin museum]. The description fits Thallis ianthina Erichson, 1842 (Erotylidae) from Tasmania [Van Diemenland]. There are more specimens of the latter in the Grouvelle and Oberthür collections (Muséum National d’Histoire Naturelle, Paris, France), one of them in Oberthür’s coll. labelled ‘ Thallis janthina Er. // Schaum, ex col. Reitter’, but none explicitly labelled as the type of Ips janthinus Reitter. The reference in Reitter’s description to the Berlin museum, depository of the Erichson collection, suggests that Reitter, not aware of the description by ERICHSON (1842), repeatedly described his Thallis ianthina , this time in a wrong combination. That’s probably the reason why Ips janthinus Reitter, 1877 was omitted from the Catalogue of Nitidulidae by GROUVELLE (1913) and appeared again only as ‘ Glischrochilus (?)’ in the bibliography of the genus by MILLER & WILLIAMS (1981). As a formal solution, we therefore propose to consider the name Ips janthinus Reitter, 1877 a junior synonym of Thallis ianthina Erichson, 1842 .
