Michael C. Thomas Festschrift Contribution
Glaresis franki Keller and Skelley new species and Glaresis thomasi Keller and Skelley new species (Coleoptera: Scarabaeoidea: Glaresidae) are described and illustrated. They represent the first record of the family for the West Indies. Both species are placed into the phoenicis species group. A key to the two West Indies species is presented.
Resumen. Se describe e ilustra Glaresis franki Keller y Skelley nueva especie y Glaresis thomasi Keller y Skelley nueva especie (Coleoptera: Scarabaeoidea: Glaresidae). Estas especies representan el primer record de la familia para las indias occidentales. Ambas especies se colocan en el grupo de especies de phoenicis. Sé presenta una clave dicotómica para las dos especies de las Antillas.
The scarabaeoid family Glaresidae Kolbe (1905) has one extant genus, Glaresis Erichson (1848) with 84 species worldwide (Zidek 2015; Paulsen 2016; Král et al. 2017; Král and Hrůzová 2018; Ochi et al. 2019; Ziani et al. 2020). The family is currently known from all continents except for Australia and Antarctica. The genus Glaresis was first revised for North America by Gordon (1970), having species added by Gordon (1974) and Warner (1995), and a subsequent update and expanded revision for all of the Americas by Gordon and Hanley (2014). Gordon and Hanley (2014) reported 35 species from the Western Hemisphere, and Paulsen (2016) added two species from South America. The Nearctic is the most speciose zoogeographical region (31 species; Zidek 2015; Král et al. 2017), while the neotropics have the smallest number of described species (8 species; Král et al. 2017; this paper).
Here we report the first family record from Hispaniola in the West Indies and describe two new species in the genus Glaresis, raising the species total to 86. Specimens were collected in both the Dominican Republic and Haiti and are morphologically distinct from any congeners from the New World.
