Notes:
Hemming (1967) stated:-

There was a serious defect in the way in which this name appeared in Kaye's paper, for the correction of which it has been necessary to submit an application to the Commission. The name Iaspis was introduced by Kaye in a catalogue of the butterflies of Trinidad, where it appeared in the portion relating to the family Lycaenidae. Kaye designated as the type-species of this genus the nominal species Symmachia (?) temesa Hewitson, 1870. It is here that the difficulty arises, for the above species is not a Lycaenid but a Riodinid, and does not agree in any way with Kaye's description of his genus Iaspis. The explanation of this extraordinary event was provided by Druce in 1906 (Ann. Mag. nat. Hist. (7) : 17 : 334-335) in a "Note on the genus Iaspis Kaye". After drawing attention to Kaye's mistake, Druce-went on to observe that at almost exactly the same time Hewitson had established a nominal species in two different genera, to each of which he gave the specific name temesa. One of these was the Riodinid Symmachia (?) temesa Hewitson, 1870 (Descr. New Spec. Equat. Lep. : 52), a taxon which was redescribed and figured by Hewitson in the following year (1871) (Ill. exot. Butts. 4 : [85], pl. [46], figs 17, 18); the other species was the Lycaenid Thecla temesa Hewitson, [1869] (for which the reference has been given at the head of the present note). Druce concluded - no doubt, correctly - that it was the Lycaenid species and not the Riodinid which Kaye had intended to designate - and which he believed he had designated - as the type-species of the genus Iapsis.

Subsequent authors have interpreted Iaspis in accordance with the undoubted intention of Kaye, that is, as a Lycaenid, but, as matters stand, this is undoubtedly incorrect, for Kaye unequivocally designated the Riodinid Symmachia temesia Hewitson as type-species. It is to regularise the situation described that the Commission has been asked to use its Plenary Powers to designate as the type-species of the genus Iaspis Kaye the Lycaenid nominal species Thecla temesa Hewitson, [1869], thus giving valid force both to Kaye's original intention and also the practice of later authors.

Cowan (1968) made the following comment for this and other genera

Opinions published in September and December 1967 in Bull. zool. Nomencl. 24, parts (4) and (5) CONFIRMED the forecasts given in the List [Hemming, 1967] for the following genera;

Adopaeoides Godman; Op. 825
Arisbe Hübner; Op. 823
Artines Godman; Op. 826
Gegenes Hübner; Op. 827
Halpe Moore; Op. 828
Iaspis Kaye; Op. 821
Napaea Hübner; Op. 820
Papias Godman; Op. 829
Phanes Godman; Op. 830
Phrissura Butler; Op. 824
Telicota Moore; Op. 831
Ypthima Hübner; Op. 819

Thecla temesa Hewitson, [1868] was designated as the type-species for Iaspis Kaye, 1904 after designation under the plenary powers and placed on the Official List of Specific Names in Zoology (Opinion 821), The Bulletin of Zoological Nomenclature, 24 : 214. Iaspis was placed on the Official List of Generic Names in Zoology.

The higher classification used here follows Lamas (2008).
