Hemiceratoides hieroglyphica vadoni Viette, 1976 . Bulletin mensuel de la Société Linnéenne de Lyon 45 (6): 227.

Type material: ♂ holotypus, by original designation, in MNHN (examined). Type locality (verbatim): Madagascar Est, baie d’Antongil, base de la presqu’île Masoala , Hiaraka , 500 m.

Diagnosis: Hemiceratoides vadoni is straightforwardly distinguishable from other orange-hindwinged congeners by the combination of its pattern, which is as in H. sittaca , i.e. with slender, dark coloured forewing and hindwing with well-expressed fuscous elements (these being, however, sharper in sittaca ), and the male antenna, which has long pectinations as in H. hieroglyphica and H. ornithopotis sp. nov.. In the male genitalia, the median saccular lobes of the left and right valva are similarly shaped and sized, although differently oriented, there is no constriction between valvula and cucullus, and the valvae are terminated by three processes as in H. hieroglyphica , though in H. vadoni the median one is much longer than in the other Madagascan endemic; the mastigojuxta is long, flexible, and bears spines on either sides in its distal fourth ( Fig. 9B View Figure 9 ); the phallus has a long, narrow coecum and only a thin sclerotized strip in place of the auriculate carina, and shows vesical diverticula as in Fig. 10B View Figure 10 . The female is unknown.

Distribution: A rarely collected species endemic to Madagascar. Previously only reported from the Baie d’Antongil area in the North-East of the island, where it has been collected from mid-October to January at elevations between 200 and 1000 m (Viette 1976; MNHN collection data: N = 4), the specimen illustrated here in Fig. 7D View Figure 7 (ex coll. C. Oberthür, in NHMUK) is labelled instead as from ‘Sud de Madagascar, 1922’. Similarly labelled specimens of other species seem to originate from other regions of Madagascar, being nowadays known as ‘microendemics’ of particular areas, but the remarkable environmental changes introduced in the island over the last century may have altered the distribution of species that were once more widespread ( Green and Sussman 1990, Harper et al. 2007, Schüssler et al. 2018, Vieilledent et al. 2018).

Molecular resources: None.

Remarks: Described as, and supposed to be, the oriental Madagascan subspecies of Hemiceratoides hieroglyphica by Viette (1976); the same author subsequently upgraded vadoni to specific rank without providing any comments (Viette 1990).
