Types. Lectotype of Brixia migratoria here designated, ɗ, AUSTRALIA, Qld: F.P. Dodd (BMNH). Lectotype of Leirioessa tortricomorpha , here designated, ɗ, AUSTRALIA, Qld: Kuranda, viii.1904 (BPBM). Paralectotype: AUSTRALIA, Qld: 1 Ψ, Cairns, viii.1904 (BPBM).

Remarks. Distant’s (1907) original description of Brixia migratoria does not specify whether the type series consists of more than one specimen. Only one specimen has been found in the BMNH and it is here designated as lectotype in order to clarify the identity of the species. A lectotype and paralectotype for Leirioessa tortricomorpha are here designated to give a diagnostic reference for that name. Holzinger et al. (2002: 124) listed Leirioessa as a synonym of Andes without listing the included species.

Colour. Vertex light or mid brown with two longitudinal, white stripes; frons mid or dark brown, lateral carinae paler, without dots; pronotum light brown; mesonotum light to mid brown; legs light brown; forewing hyaline, colourless, with transverse band (tb1) wide, mid to dark brown, extending to immediately basad of pterostigma, covering fork CuA1+CuA2 and terminating at CuP, forewing with transverse band (tb2) narrow, mid to dark brown, around basal cell reaching into clavus, forewing with mid or dark brown marks scattered across wing, apical half of wing with light brown patches; veins concolorous with cells, tubercles mid brown, pterostigma light brown; abdominal sternites light or mid brown.

Morphology. Body length: ɗ 5.6–6.6 mm, Ψ 6.1–7.1 mm.

Head: Vertex 0.8–1.0 x as long as wide. Junction of vertex and frons slightly angular and distinctly produced in lateral view. Frons 2.5–3.1 x longer than wide; median carina incomplete, covering 1/3 to 1/2 of length of frons; lateral carinae not extending laterally, not concealing base of antennae; median ocellus separated from frontoclypeal suture by less than its own diameter. Rostrum slightly or distinctly surpassing hind coxae.

Thorax: Forewing 2.4–2.7 x longer than wide; CuA1+CuA2 forking 1/5–1/6 away from apex of clavus; costa with 11–16 tubercles. Hind leg: tibia with 2–6 small to medium sized lateral spines; 1st tarsomere with 8–9 apical teeth; 2nd tarsomere with 7–8 apical teeth and 1–3 very fine setae underneath row of apical teeth.

Male genitalia: Anal tube as in Figs 7 D–E; genital styles and ventromedian process as in Figs 7 F–G. Aedeagus ( Figs 7 A–C): phallotheca with long, very slender cucullus, shaped as in Fig. 7 A, rim of cucullus smooth, in left lateral view convex ( Fig. 7 A); flagellum unarmed; virga elongated, sinuate.

Remarks. The structure of the male genitalia, in particular the shape of the cucullus, is shared with Andes brunneus Muir (1925) and A. indistinctus Muir (1925) from Borneo. In A. brunneus , however, the cucullus is smaller, covering only the apical third of the phallotheca, whereas in A. migratorius half to 3/4 of the phallotheca is covered by the cucullus. Andes indistinctus differs from A. migratorius in the shape of the anal tube, which bears a triangular process with an acute apex on its apical lobes.

Andes migratorius can be distinguished from all other Australian Andini by the unique combination of a long, very slender cucullus and an unspotted face.
