Ardozyga Key

I have been working on a key for Ardozyga (not yet fully complete or tested) Species at the bottom still to be looked at:

Happy for people to look and add comments:

E. Meyrick Original key page 333 – 338 in Proceedings of the Linnean Society of New South Wales Sydney, v29, Descriptions of Australian Micro-Lepidoptera, XVIII.

This Key then adds species identified by Meyrick, Turner, Lower and others at later dates.

Terms have been modernised to try to make the key clearer. The biggest issue with this key is the identification using the hind-wing unless open and seen, often unable to be determined. (I might at a later date look for a more visible characteristic). Please be aware that this is my interpretation based on others descriptions of the species, always once you reach a species look for the taxonomic description to see if its other characteristics match.

Lobesia in Australia

Lobesia are a difficult group in Australia. The following are the original descriptions for the various species (not including undescribed species on BOLD Taxonomy). These descriptions have been modified to modern language in the hopes that this will help people to identify their images to species level (for example using the word 'band' instead of the word 'fascia'. There does appear to be character differences between each of the species, which should allow for an effective key to be developed.

Cnephasia arescophanes n. sp. [Lobesia arescophanes]
♀, 12 mm. Head and thorax brownish. Palpi 2; brownish. Antennae pale brownish. Abdomen grey. Forewings with costa gently arched, apex sub-rectangular, termen straight, slightly oblique; grey with brown markings; basal patch large, posterior edge angled, grey with brown transverse lines; a narrow band from mid-costa to 3/5th dorsum; a series of costal marks; a circular subterminal spot connected by slender lines with tornus and mid-termen; a dark brown apical dot; cilia grey. Hindwings and cilia pale grey.

North Queensland.

Capua discotypa, Steriphotis extrusana, Grapholita extrusana n. sp.
[Lobesia extrusana]
♀, 12 - 16 mm. Head and thorax brown (fuscous). Palpi 3; brown (fuscous). Thorax dorsally suffused with dark fuscous. Antennae pale brownish, with narrow blackish rings. Legs whitish; anterior and middle tibiae and tarsi fuscous, with ochreous-whitish annulations. Forewings elongate, posteriorly dilated, costa straight, towards apex gently arched, apex rounded (obtuse), termen slightly rounded; brown-whitish, closely set with fine fuscous transverse lines and some dark-fuscous irroration; costa and dorsum finely marked with dark-fuscous; basal patch slightly darker, forming a suffused dark fuscous spot on dorsum towards base, outer edge angulated near costa; a strongly curved anteriorly convex blackish-fuscous streak rising from dorsum beyond middle, extending 2/3rd across wing, its extremity strongly curved over posteriorly; a small slightly darker spot on middle of costa; a large fuscous apical patch, becoming darker fuscous anteriorly, its edge running from 2/3rd of costa to tornus, including two pairs of whitish costal marks, a whitish dot on termen above middle, and some indistinct pale markings towards apex: cilia rather dark fuscous, with rows of whitish points. Hindwings dark fuscous; towards base thinly scaled; cilia whitish-fuscous, with darker sub-basal line.

Queensland.

Steriphotis peltophora [Lobesia peltophora]

♂ ♀ 12 - 13 mm. Head light fuscous. Palpi fuscous mixed with dark fuscous, tip whitish. Thorax light fuscous sprinkled with white, anteriorly, and posteriorly mixed with dark fuscous and blackish. Forewings elongate, posteriorly dilated, costa hardly arched, apex obtuse, termen slightly rounded, somewhat oblique: whitish-fuscous with bluish-violet iridescence, with some scattered dark fuscous markings; costa and
dorsum marked with dark fuscous, costa with pairs of whitish marks: markings brown partially edged and marked with black: a narrow basal band, widest on dorsum; a straight slightly oblique transverse streak about 1/3rd, hardly reaching dorsum, less developed in ♂; central band well-marked, little oblique, moderate, narrowed towards costa, posterior edge prominent or angulated in middle ; a small spot on costa at 2/3rd, and one at apex; a rounded blotch before termen in middle, connected with middle of termen, and with a suffused striga or undefined branch running to tornus: cilia fuscous with obscure indications of violet-whitish bars. Hind-wings fuscous, thinly scaled towards base, darker posteriorly and on veins; cilia whitish-fuscous, with fuscous subbasal line.

Queensland: Brisbane.
