title: A New Species Of Glaresis Erichson From The Iberian Peninsula (Scarabaeoidea: Glaresidae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Verdú, José R., Galante, Eduardo (2001): A New Species Of Glaresis Erichson From The Iberian Peninsula (Scarabaeoidea: Glaresidae). The Coleopterists Bulletin 55 (3): 272-278, DOI: 10.1649/0010-065x(2001)055[0272:ansoge]2.0.co;2AbstractGlaresis thiniensis new species is described from material collected at light in littoral sand dunes from eastern Iberian Peninsula. A new record of the other known Iberian species of Glaresis Erichson, G. hispana (Báguena), is provided. Diagnostic characters of both species include the presence/absence of mesotibial fossa in the metasternum, the form of the clypeus and meso­ and metatibia, the number and size of teeth on the metatrochanter and femora and the form of male genitalia. These characters and others as the form of mandibles, length of metatarsomers, and the form of outer horseshoeshaped portion of metatibia can be used to separate G. thiniensis from the North African species: G. mandibularis Petrovitz, G. tripolitana Petrovitz, G. carthagensis Petrovitz, G. pardoi Petrovitz and G. mauritanica Petrovitz. A map with the known distribution of the Iberian species is also provided.The genus Glaresis Erichson, with about 50 species world­wide, is widely distributed and has been recorded on the Iberian Peninsula (Spain), Morocco, Mauritania, Eastern Africa, South Africa, Turkey, Hungary, Ukraine, North Caucasus, eastern Romania, Central Asia, India (Thar desert), western Madagascar, western North America and South America (Argentina) (Panin 1957; Pardo­Alcaide 1958; Martínez et al. 1961; Petrovitz 1968 a, b; Gordon 1970, 1974; Paulian 1981; Scholtz 1983; Scholtz et al. 1987; Ávila 1990; Ávila and Sánchez­Piñero 1992). Generally, most species occur in arid regions and particularly in littoral and continental sandy areas. Larval morphology of glaresid species is unknown and very little is known about their biology. Nearly all Glaresis specimens captured have been taken at artificial light and exceptionally have been collected beating plants (Gordon 1974). One species has been found under sand on roots of plants (Reymond 1950).In the Iberian Peninsula, Glaresis hispana (Báguena) was the only known species of the genus and one of the most rare species of Scarabaeoidea. This species occurs in the most arid and semiarid environments of the Iberian Peninsula. All recorded specimens have been collected at light (Ávila and Sánchez­Piñero 1992).In this paper, Glaresis thiniensis new species, is described from material collected with light traps in littoral sand dunes from eastern Iberian Peninsula (‘‘Albufera Natural Park,’’ Valencia, Spain). Generally, characters of use in identifying species include the form of the clypeus and meso­ and metatibia, the number and size of teeth on the metatrochanter and femora and the form of male genitalia (Gordon 1974).For study of species, heating the specimens in KOH and scrubbing with a brush are usually recommended for remove the covering (Gordon 1970). Generally, ultrasonic exposure of specimens in ether­alcohol (1:1) solution for a few minutes, is also effective.
