Tribe Ablaberini

Among the type material of Ablaberini described by C.P. Thunberg and L. Gyllenhal in the Stockholm Museum of Natural History, only species of the genera Camenta Er- ichson, 1847 and Ablabera Erichson, 1847 were found. Species of both genera await a comprehensive taxonomic revision and consequently, little can be said about the current status of the species at this moment. Thus, we decided to not include any redescription because a broader taxonomic knowledge of these genera is needed.

Ablabera analis ( Thunberg, 1818)

( Fig. 3A–D )

Melolontha analis Thunberg, 1818: 427 .

Ablabera analis : Blanchard 1850: 101; Péringuey 1904: 86; Dalla Torre 1912: 75.

Type material examined. Lectotype (here designated). ♀ “ Uppsala Univ. Zool. Mus. Thunbergsaml. nr. 14777 Hoplia analis TYP ” ( UUZM).

Additional material examined. 1 ♀ “ Uppsala Univ. Zool. Mus. Thunbergsaml. nr. 3326 Hoplia analis TYP ” ( UUZM) .

Remarks. The exact identity of this species and its potential synonymy is difficult to establish as male speci- mens are not available.

The specimen nr. 3326 of the supposed type series was not designated as paralectotype as not an Ablabera species, but appears to be a female of Maladera holosericea (Scopoli) which was mislabeled and which possibly is not part of the type series.

Ablabera clypeata ( Gyllenhal, 1817) stat. rev.

( Fig. 4A–E )

Melolontha clypeata Gyllenhal, 1817: 70 .

Ablabera clypeata : Blanchard 1850: 101; Burmeister 1855: 137; Péringuey 1904: 78; Dalla Torre 1912: 76.

Type material examined. Lectotype (here designated). ♀ “ Uppsala Univ. Zool. Mus. Gyllenhal saml. Typ nr. 1453/ a” ( UUZM).

Remarks. The here designated lectotype specimen was the only available syntype specimen. No other syntype specimen was present in the Stockholm Museum.

Ablabera clypeata and A. totta ( Thunberg, 1818) were listed by Péringuey (1904) as junior synonyms of Ablabera splendida (Fabricius, 1781) . However, the examination of both Thunberg’s type specimens revealed that the types belong to different species and they are not A. 28 Dirk Ahrens et al.

splendida . Since there is no evidence in previous works that either Péringuey (1904) or other authors examined the type of any of the tree species, it seems reasonable to treat them as valid taxa until the group is comprehensively revised.
