Abstract
Pachyrhynchus banglas sp. nov. and P. esperanza sp. nov., two new species of the Entiminae Pachyrhynchini genus Pachyrhynchus Germar, 1823 (Curculionidae) from the Philippines, Mindanao Island, are described. Diagnosis of each taxon is provided, and habitus photographs and illustrations of male and female genitalia are given. The authors also propose a new taxonomical arrangement of two species groups: Pachyrhynchus amabilis species group and Pachyrhynchus schoenherri species group. The new synonymy: Pachyrhynchus elegans Waterhouse, 1842 (= P. eos Heller, 1924, syn. n.) is also established.
