“…Adults share the main external diagnostic characters with other species of Udeus while being easily distinguished by colour and pilosity. Like other species of Eugnomini, there is marked sexual dimorphism with a mucronate tibia in males only (Bondar 1957; Cawthra 1966; Champion 1902; Kuschel 1952) and a central metasternal concavity extending into the first and second ventrites in males (Champion 1902). New sexually dimorphic characters reported here include longer setae at the base of tibiae and femora in males and a markedly distinct shape of ventrite V, trapezoidal in males and triangular in females.…”

“…Udeus is the most diverse genus of Neotropical Eugnomini with 11 known species reported from Mexico (one species), Guadeloupe (one species), Martinique (one species), Panama (one species), French Guiana (three species), Bolivia (one species), Paraguay (one species), and Brazil (three species) (O'Brien & Wibmer 1982; Rheinheimer 2018; Rheinheimer 2019; Wibmer & O'Brien 1986). The three known species of Udeus from Brazil are distributed in the Atlantic Forest (Bondar 1957; Voss 1941). These weevils are recognised by a set of characters similar to other Eugnomini, such as large eyes, elongate head, exodont mandibles, flexible maxillae with long palps, contiguous procoxae, femora with an internal tooth, mucronate tibiae, and ventrites with straight posterior margins (Caldara, Franz, & Oberprieler 2014; Cawthra 1966; Champion 1902).…”

Nonetheless, the main diagnostic character of Udeus is the elongate tarsi with the last tarsomere longer than tarsomeres I–IV together (Bondar 1957; Champion 1902).…”

“…The first report on the biology of the genus registered U. cecropiae (Bondar) and U. sergioi (Bondar) associated with inflorescences of two species of Cecropia Loefl. (Urticaceae) (Bondar 1957). More recently, Mendonça (2014) recorded the association of two Udeus species with the female and male inflorescences of Cecropia glaziovii Snethl., suggesting they may be pollinators of this species.…”

Udeus Champion, 1902 is a weevil genus in the tribe Eugnomini associated with the inflorescences of Cecropia Loefl. (Urticaceae), with 11 valid species distributed in the Neotropics. Species of Udeus are generally rare in collections and their biology is poorly known, despite a high abundance in nature. Here, we describe Udeus cerradensis Lira, de Medeiros & Grossi, sp. nov. from the Brazilian Cerrado, including the first descriptions of larvae and pupae for a Neotropical eugnomine. We assess their role as potential pollinators of their host plant Cecropia saxatilis Snethl. and find that adults do not visit pistillate flowers and therefore are unlikely to be pollinators. This contrasts with previous reports in a different pair of species in Cecropia‐Udeus, suggesting that pollinator agents vary between species in this plant genus. Finally, we provide notes about the predation of larvae of U. cerradensis by social wasps Synoeca surinama (L.) and Protopolybia aff. sedula (Saussure), revealing that, in this instance, an endophytic larva does not prevent predation by a behaviourally flexible predator. This study is the first of a series on the natural history of Udeus and their specialised interactions with host plants.
