Hemming (1967) stated:-
Halpe is a genus which was based on a misidentified type-species. The circumstances are as follows. Halpe was established with five included nominal species but none of these was designated as type-species. One of these, the nominal species Hesperia beturia Hewitson, 1868 (Descr. One Hundred New Spec. Hesp. (2) : 36), was selected as the type-species by Watson in 1893 (Proc. zool. Soc. Lond. 1893 : 93). In the same paper (loc. cit. : 109) Watson described an allied species under the name Halpe moorei. Watson added (: 110) that this species usually stood in Indian collections as beturia Hewitson owing to the fact that Hewitson himself had confused the taxon occurring in the Nilgiris (now named moorei by Watson) with a quite different species occurring in Celebes. This piece of synonymy which corresponds with the evidence afforded by the type-specimens of beturia and moorei in the British Museum, has been accepted by all subsequent authors. Unluckily, one aspect of this case was overlooked by Watson when he selected Hesperia beturia Moore to be the type-species of the genus Halpe ; this was that, when in 1878 Moore established Halpe and placed in it what he then identified as beturia Hewitson, this was the Indian species (later named moorei by Watson) and not the true beturia from Celebes. Thus, through Watson's action Halpe became a genus based on a misidentified species. This was first pointed out by Swinhoe in 1913 (in Moore, Lep. ind. 10. (119) : 264) who thereupon cited Halpe moorei Watson as the type-species. The same course was followed by Evans in 1949 (Cat. Hesp. Europe Asia Australia Brit. Mus. : 257, 260, 265). Under the Code however it is incorrect to accept as the type-species of a genus any nominal species not cited as belonging to the genus at the time when the generic name concerned was originally published. Accordingly, the Commission is being asked to regularize the position by designating Halpe moorei Watson to be the type-species of this genus under the Misidentified-Type-Species Procedure laid down in Article 70 of the Code. For the sake of continuity the name Halpe is here provisionally treated as though the action indicated above had already been taken by the Commission.
It must here be noted that in 1925 (Ann. ent. Soc. Amer. 18 : 88) Lindsey advanced the view that the nominal species Halpe ceylonica Moore, 1878, (Proc. zool. Soc. Lond. 1878 : 690, pl. 45, fig. 9) had been selected as the type-species of the genus Halpe by Kirby in  (in Zool. Rec. 15 (year 1878) (Ins.) : 188). Lindsey's statement is incorrect in every respect, and must have been due to some confusion in his notes, for Kirby did not designate a type-species for this genus and indeed did not cite Halpe ceylonica at all.
Finally, it must be noted that in 1949 (loc. cit. : 260) Evans treated the taxon represented by the nominal species Halpe moorei Watson as being the same as that represented by the older-established nominal species Hesperilla porus Mabille, 1876 (Bull. Soc. ent. Fr. (5) 6 : cxcix).

Halpe moorei Watson, 1893 was designated as the type-species for Halpe Moore, 1878, using the plenary powers of the Commission. Halpe moorei was placed on the Official List of Specific Names in Zoology and Halpe on the List of Generic Names in Zoology, (Opinion 828), The Bulletin of Zoological Nomenclature, 24 (4) : 228.
HALPE was included within the subfamily HESPERIIDAE: HESPERIINAE by Ackery et al., in Kristensen (1999).
The higher classification used here follows Lamas (2008).
