Hapalogenius Hagedorn

Beaver, Roger A, 2010, Taxonomic notes on the afrotropical genera Hapalogenius Hagedorn, Hylesinopsis Eggers, and Rhopalopselion Hagedorn (Coleoptera, Curculionidae, Scolytinae), ZooKeys 56, pp. 157-170 : 159-160

Hapalogenius Hagedorn Fig. 1

Hapalogenius Hagedorn 1912: 352. (Type species: Hapalogenius globosus Hagedorn, monobasic).

Pseudohylesinus Eggers 1920a: 234. (Type species: Pseudohylesinus togonus Eggers, monobasic, preoccupied by Swaine 1917: 11).

Metahylesinus Eggers 1922: 165. (Type species: Pseudohylesinus togonus Eggers, automatic, replacement name for Pseudohylesinus Eggers nec Swaine).

Pseudophloeotribus Eggers 1933: 18. (Type species: Pseudophloeotribus africanus Eggers, original designation). (The subsequent designation by Schedl 1960: 75 was unnecessary).

Glochicopterus Schedl 1954: 75. (Type species: Glochicopterus baphiae Schedl, monobasic).

Hapalophloeus Schedl 1966: 363. (Type species: Metahylesinus brincki Schedl, original designation).

Hemihylesinus Schedl 1967: 224. (Type species: Hemihylesinus endroedyi Schedl, monobasic). Aridiamerus Schedl 1982: 284. (Type species: Aridiamerus angolensis Schedl, monobasic). ( Hylesinopsis angolana Wood 1988a: 32 is an unnecessary replacement name.)

Eggers (1927), having compared the types of Phloeotribus fuscipennis (Chapuis, 1869) and Hapalogenius globosus , concluded that the species were identical. Chapuis’ name had priority, but the species did not belong in Phloeotribus and was transferred to Hapalogenius . This conclusion was accepted by Schedl (1963a). Wood and Bright (1992: 94) placed Phloeotribus fuscipennis and its synonym Hapalogenius globosus in Hylesinopsis , overlooking the fact that Hapalogenius has priority, but they also ( Wood and Bright 1992: 96) cited Hapalogenius , with its type species, Hapalogenius globosus , as a synonym of Rhopalopselion . As noted above, Alonso-Zarazaga and Lyal (2009) reinstated Hapalogenius as the correct name for the species treated by Wood and Bright (1992) under Hylesinopsis . I consider that Hapalogenius is a valid genus, but that it is distinguished from Rhopalopselion and Hylesinopsis by the characters given in the key above, and with the synonymy given. I have examined the type species of all the genera involved. In addition to the type species listed above, the following 30 nominal species can be assigned to the genus: Hapalogenius acaciae Schedl*, Hapalogenius congonus Schedl, Hapalogenius immaturus Schedl*, Hapalogenius lesnei Eggers, Hapalogenius lonchocarpae Schedl*, Hapalogenius maculatus Schedl*, Hapalogenius occidentalis Schedl*, Hapalogenius primus Schedl, Hapalogenius rufus Schedl*, Hapalogenius senegambiensis Schedl, Hapalogenius subseriatus Schedl*, Hapalogenius suturalis Schedl*, Hylesinopsis kenyae Wood, Hylesinopsis kenyae ugandae Wood*, Hylesinus horridus Eggers, Hylesinus pusillus Gerstaecker, Metahylesinus brincki Schedl*, Metahylesinus dimorphus Schedl, Metahylesinus hispidus Eggers, Metahylesinus orientalis Eggers*, Metahylesinus quadrituberculatus Schedl, Metahylesinus striatus Schedl*, Metahylesinus sulcatus Eggers*, Pseudophloeotribus africanus Eggers*, Pseudophloeotribus oblongus Eggers*, Pseudophloeotribus rhodesianus Eggers*, Pseudophloeotribus seriatus Eggers, Pseudophloeotribus squamosus Eggers*, Pseudophloeotribus variegatus Eggers*, Rhopalopselion atakorae Schedl* (* - type(s) examined). The genus clearly belongs in the tribe Hylesinini sensu Wood (1986a), but this tribe seems likely to be paraphyletic (e.g. Farrell et al. 2001, Jordal et al. 2008, McKenna et al. 2009), and may need to be redefined.
