Genus Odontolytes Kozhantshikov, 1916DiagnosisLength 3.0 – 8.0 mm. Body oval or elongate, dark reddish brown to brown piceous. Head broad, almost as wide as lateral margins of pronotum, variably punctate. Pronotum with variably shaped and distributed punctures; lateral margins, explanate or not, transverse or not. Elytra with humeral denticle developed. Mesoventrite with one or two callosities, or if callosity not present, mesometaventral carina present. Mesoventrite and metatarsus with dense setae on its ventral surface or not.RemarksOdontolytes has 19 recognized species reported from the USA (Florida), Cuba, and several countries from Central and South America (Stebnicka 2009). Stebnicka (2002) presents a key to all species described at the time. Odontolytes waoraniae Stebnicka & Skelley, 2005 and O. tectipennis Stebnicka & Skelley, 2005 were described after Stebnicka (2002) and are absent from the key. The current taxonomic status of Odontolytes was reviewed by Krell et al. (2011).Key to species of Odontolytes from Brazil (adapted from Stebnicka 2002) (Portuguese version in Supp. file 1)1.
