Ordo: Coleoptera
Familia: Curculionidae
Name
Peltophorus Schoenherr, 1845: 451 – Wikispecies link – Pensoft Profile
- [[|]] = Apatorhynchus Desbrochers, 1891: 40 [Syn.: Champion 1906b[1]: 20]. Type species: Zygops leopardinus Desbrochers, 1891 [by monotypy].
- [[|]] = Opalocetus Desbrochers, 1910: 126 [unjustified replacement name for Peltophorus (Champion 1910b[2]: 211)].
Type species
Peltophorus polymitus Boheman, 1845 [by original designation].
Gender
Masculine.
Diagnosis
This genus is similar only to Zygops with the large exposed pygidium that is visible in dorsal view and the sulcate subapical pronotal constriction, and can be readily distinguished from Zygops by the following characters: the shape of the eyes, which in Peltophorus are generally not as large and not extending as laterally on the head as in Zygops, the distal setal comb of the metatibia that extends more than a third to the base of the tibia (Champion 1906b[1]: 20; Fig. 33) the femora always with one large triangular tooth (with one or several smaller teeth in Zygops) and the unique mesoventrite that is ventrally protruding along the posterior margin (Fig. 16), and differs from the mesoventrite of Zygops which is usually unmodified (or with small posterolateral processes in a few species).
Notes
See Böving (1926)[3] for description of larval and pupal morphology and González-Hernández et al. (2015)[4] and Figueroa-Castro et al. (2016)[5] for an overview of the feeding damage of P. polymitus Boheman and P. adustus (Fall) in Mexico.
Keys
Sleeper 1963[6]: 216 (to U.S. species), Casey 1892[7]: 459 (to U.S. species).
Phylogenetic relationships
Related to Zygops and the South American genera Parazygops and Colpothorax due to the exposed pygidium, large metepimeron, transverse scutellum, and sulcate subapical pronotal constriction.
Host associations
The species of Peltophorus are associated with several species of Agave L. (Asparagaceae Juss.), including Agave palmeri Engelm. (Sleeper 1963[6]: 216, González-Hernández et al. 2015[4], Figueroa-Castro et al. 2016[5]).
Described species
Three.
Range
Southwestern U.S.A., Mexico, Honduras.
