| Geographical distribution of the species of Entimus | |
Entimus is a genus of broad-nosed weevils belonging to the family true weevil and the Entiminae subfamily.
The species of the genus Entimus can reach a length of about 12–45 millimetres (0.47–1.77 in). They usually have green, blue and gold iridescent scales. [1]
These species can be found from Mesoamerica to northeastern Argentina.
This genus includes the following eight species:
The following cladogram represents the diversification of Entimus genus according phylogenetic analysis based on external morphology. It shows two vicariant events, where E. arrogans (Mesoamerican) diverged from South American species. Later, E. granulatus (Amazonian). [1] [2]

Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than 6 mm in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
Otiorhynchus is a large genus of weevils in the family Curculionidae. Many species of the genus, particularly the black vine weevil and the strawberry root weevil, are important pests, both as larvae and as adults. Larvae feed on plant roots. Adults are flightless with fused elytra and feed at night on plant foliage. In many species of the genus at least some races are polyploid and parthenogenetic, while the rest of the races and species are diploid and bisexual. Otiorhynchus weevils, particularly O. scaber, have been a popular subject for studies of the evolution of parthenogenesis. The genus is native to the Palearctic region. However, sixteen species were inadvertently introduced to North America and have become widespread there.
The Entiminae are a large subfamily in the weevil family Curculionidae, containing most of the short-nosed weevils, including such genera as Entimus, Otiorhynchus, Phyllobius, Sitona, and Pachyrrhynchus. In comparison with their stunning diversity, only a few of these weevils are notorious pests of major economic importance. Entimines are commonly encountered in the field, including urban environments, and abundant in entomological collections.
Entimus splendidus is a species of broad-nosed weevils belonging to the family true weevil and the Entiminae subfamily.
Rhynchophorus, or common name palm weevils, is a genus of beetles in the weevil family, Curculionidae. Palm weevils are major pests of various trees in the family Arecaceae throughout the tropics including: coconut, Areca catechu, species of the genus Phoenix, and Metroxylon sagu. Two species are invasive pests outside their native ranges, Rhynchophorus ferrugineus and Rhynchophorus palmarum.
Entimini is a Neotropical weevil tribe in the subfamily Entiminae that includes 46 described species.
Eustylini is a primarily Neotropical weevil tribe in the subfamily Entiminae.
Geonemini is a weevil tribe in the subfamily Entiminae.
Ophryastini is a weevil tribe in the subfamily Entiminae.
Pachnaeus opalus, the northern citrus root weevil, is a species of broad-nosed weevil in the family Curculionidae. It is found in North America.
Pandeleteius is a genus of broad-nosed weevils in the family Curculionidae. There are over 150 described species in Pandeleteius, distributed across the Americas. Most species in the genus were described by Anne Howden.
Pachnaeus is a genus of broad-nosed weevils in the family Curculionidae. There are about seven described species in Pachnaeus.
Artipus is a genus of broad-nosed weevils in the beetle family Curculionidae. There are about 10 described species in Artipus.
Myllocerus is a genus of oriental broad-nosed weevils in the beetle family Curculionidae. There are at least 330 described species in Myllocerus.
Neomastix is a genus of true weevils in the family of beetles known as Curculionidae. It is found in the Nearctic realm. The type species is N. solidaginus.
Rhinostomus frontalis is a species of weevils, previously placed in a genus called Yuccaborus and known as the yucca weevils.
Brachyolus is a genus of broad-nosed weevil in the family Curculionidae.
Namaini is a tribe of soil-associated weevils from South Africa in the subfamily Entiminae.
Lachnopus is a genus of broad-nosed weevils in the family Curculionidae distributed in the Caribbean Region.
Pteroptyx is a genus of fireflies in the subfamily Luciolinae found in Southeast Asia. It has long been noted for the ability to perform synchronous flashing, though not all species synchronize. These synchronizing species have been found on so-called 'firefly trees' and created a growing firefly-watching tour industry in some regions. Species of the genus have been identified in Malaysia, Thailand, the Philippines, and Hong Kong.
