Review of the clavatus group of the lanternfly genus Pyrops (Hemiptera: Fulgoromorpha: Fulgoridae)
(2017)
The clavatus group of Pyrops Spinola, 1839 is reviewed and redefined. The new combination Pyrops atroalbus (Distant, 1918) comb. nov. is proposed, as atroalbus is reinstated as a full species from status of subspecies of Pyrops watanabei (Matsumura, 1913). Pyrops nigripennis (Chou & Wang, 1985) and Pyrops clavatus mizunumai (Sato & Nagai, 1994) are proposed as junior synonyms of P. clavatus (Westwood, 1839). The Philippine species P. polillensis (Baker, 1925) is removed from the group and not attributed to any of the currently defined species groups. Hence, the clavatus group is restricted to continental Southeast Asia and Taiwan and contains three species: P. atroalbus comb. nov., P. clavatus and P. watanabei. A key to the species of the group and illustrations of the male genitalia are provided. The intraspecific colour variation in the group is discussed and illustrated. The genus Pyrops is removed from the subfamily Fulgorinae and not attributed to any of the currently defined subfamilies of Fulgoridae.
The species group effusus of the genus Pyrops Spinola, 1839 is reviewed and the nomenclatural history of the genus Pyrops is briefly summarized. One new species from eastern Borneo, Pyrops synavei sp. nov., is described. P. gunjii (Satô & Nagai, 1994) stat. nov. is proposed as a valid species instead of a subspecies of P. whiteheadi (Distant, 1889). P. maquilinganus (Baker, 1925) is removed from the effusus group and placed back into the candelaria group. P. cyanirostris (Guérin-Méneville, 1845) is removed from the group and not attributed to any of the currently defined species groups. An illustrated key to the species of the group with the addition of P. intricatus (Walker, 1857) and a distribution map are given. The effusus group is restricted to Borneo and adjacent Laut Island and presently contains 4 species: P. effusus (Distant, 1891), P. gunjii (Satô & Nagai, 1994) stat.nov., P. synavei sp. nov. and P. whiteheadi (Distant, 1889). Trophobiosis observations with the gecko Gehyra mutilata (Wiegmann, 1835) (Reptilia: Squamata: Gekkonidae) and two species of cockroaches (Insecta: Blattodea), one Dorylaea sp. and an unidentified species of Pseudophyllodromiinae, are reported and illustrated for P. whiteheadi; observation with a cockroach, Dorylaea sp., is reported for P. intricatus.
