Metapocyrtus (Orthocyrtus) orbiferoides Schultze, 1918

Yoshitake, Hiraku, 2017, Macrocyrtus imomzodai Barševskis, 2016, a new synonym of Metapocyrtus (Orthocyrtus) orbiferoides Schultze, 1918 (Coleoptera: Curculionidae: Entiminae), Zootaxa 4254 (3), pp. 375-376 : 375-376

Metapocyrtus (Orthocyrtus) orbiferoides Schultze, 1918

Metapocyrtus (Orthocyrtus) orbiferoides Schultze 1918: 374 , pl. 1, fig. 7, female (type locality: “ LUZON, Ilocos Norte, Mount Nagapatan ”).— Schultze 1925: 180 (diagnosis).

Macrocyrtus imomzodai Barševskis 2016: 156 , fig. 1A, B, female (type locality: “ Luzon Isl., Ilocos Norte, Pagudpud ”). NEW SYNONYMY.

Specimens examined. Holotype, female, "Luzon, Ilocos N./Mt.Nagapatan/W.Schultze" (typed on beige card); " Orthocyrtus / orbiferoides / Schultze / Type /Det.W.Schultze" (hand-written on red card, partially typed); "Coll. W. Schultze/ Ankauf 1942" (typed on pale yellow card); "Staatl. Museum für/Tierkunde Dresden" (typed on white card) ( Figs. 1–3 ). No type specimens were examined for Macrocyrtus imomzodai but the habitus images published with the original description clearly support the proposed synonymy.

Distribution. Philippines (Luzon: Ilocos Norte).

Comments. The tribe Pachyrhynchini comprises more than 400 species belonging to 15 genera ( Yoshitake 2013). Presently, however, the classification of the tribe is rather confused with several ill-defined genera and subgenera, as well as with many species and subspecies placed in inappropriate taxonomic positions after their original descriptions. In addition, there are some Pachyrhynchini species placed in some genera belonging to different tribes of the Entiminae. Therefore, one must be very careful to conduct a thorough taxonomic review of Pachyrhynchini weevils prior to description of any new taxa. Comparing the habitus images of the female holotype of Macrocyrtus imomzodai ( Barševskis 2016, p. 156, Fig. 1 A, B) with that of Metapocyrtus (Orthocyrtus) orbiferoides ( Figs. 1, 2 ), there is no doubt that both specimens belong to the same species. The description of M. imomzodai by Barševskis (2016) was inadequate in lacking an overview of known taxa in the entire tribe. The generic and subgeneric placement of M. (O.) orbiferoides warrants attention as well, but its current placement is here retained since redefinitions of the genera Macrocyrtus Heller 1912 , Metapocyrtus Heller 1912 , Nothapocyrtus Heller 1912 , and several subgenera under the three genera are additionally required to resolve these taxonomic issues. The taxonomic position of this species should be revised in a comprehensive revision of the generic and subgeneric classification system of the tribe Pachyrhynchini .
