Aspilanta voraginella (Braun, 1927), comb n. Figs 5, 12, 24, 33, 80-83

Antispila voraginella Braun, 1927b: 191. Holotype ♂: USA: [Utah: Washington County] "B1206/Zion Canyon/Utah i.iv.9 [1926]- Antispila / voraginella / Type Braun.", Genitalia slide EJvN 3916 [reared from mines on Vitis arizonica] (ANSP) [examined].

Antispila voraginella; Needham et al. 1928: 290; McDunnough 1939: 91; Davis 1983b: 4; Powell and Opler 2009: 39; van Nieukerken et al. 2012: 54; Eiseman 2019: 732.

Differential diagnosis.

Wingspan ca. 4.7-5.4 mm, forewing length 2.3-2.6 mm. Externally separated from A. oinophylla and ampelopsifoliella by the darker brassy brown head scaling, the absence of a fringe line and the overall less shining metallic pattern. Relatively similar to A. argentifera, but unlikely to be sympatric with that species. Male genitalia with distinctly bilobed tegumen, fewer pecten sensilla (8-10) and phallotrema with smaller spines only.

Host plant.

Vitaceae: Vitis arizonica, unidentified Vitis .

Leafmines.

(Figs 80-83) Yellowish white blotches, without any linear part; greenish black frass irregularly in centre; mine usually formed from the confluence of several mines; as many as twenty or twenty-five pupal cases may be cut from a single leaf.

Larva.

Pale yellowish, head and prothorax hardly darker, mouthparts stand out as darker brown; a row of 5-7 brown spots on abdomen visible (Fig. 80). Larvae gregarious.

Life history.

Larvae found between 4 June and 9 August (Arizona); in all cases the adults emerged the next spring (April to June), suggesting that the species is univoltine.

Distribution.

USA: Arizona, Texas (west), Utah.
