About Tingena hemimochla (Meyrick, 1884)
The scientific name of this species is Tingena hemimochla (Meyrick, 1884), originally described by Edward Meyrick in 1884. In his original description, Meyrick gave a summary of the species' features as: forewings whitish, dusted with grey, with a blackish oblique mark beneath the fold, two discal dots, a bar from the anal angle, and a sub-apical spot; hindwings whitish-grey; head ochreous-white. His full 1884 description is as follows: This species measures 14+1⁄2 to 16 mm for both males and females. The head is ochreous-white. Palpi are ochreous-white, with the basal two-thirds of the second joint, and the base and apex of the terminal joint suffused with dark fuscous. Antennae are grey. The thorax is ochreous-white, more or less mixed with grey. The abdomen is ochreous-white. Anterior and middle legs are dark fuscous; the central ring of middle tibiae, and the apex of all joints are ochreous-white. Posterior legs are ochreous-white. Forewings are moderate in size, with a moderately arched costa, rounded apex, and very obliquely rounded hindmargin; they are white, irregularly suffused with whitish-ochreous, and sprinkled with grey and a small number of blackish scales. The costal edge is dark fuscous at the base. There is an oblique dark fuscous streak running from the fold before the middle to near the inner margin before one-third, which is generally only distinct on the fold. There is a blackish dot in the disc before the middle, and a larger blackish dot beyond the middle; these dots are sometimes connected to the apex of the oblique streak by a cloudy dark fuscous line. A cloudy dark fuscous bar extends from the anal angle almost or completely to the second discal dot. There is a cloudy dark fuscous apical spot, which is suffusedly extended along the hindmargin. A curved transverse cloudy dark fuscous line near the hindmargin, indented inwards beneath the costa, is sometimes present and is often obsolete. Cilia are whitish, with rows of dark fuscous points that form a cloudy spot at the apex and anal angle. Hindwings are whitish-grey or light grey; cilia are grey-whitish. This species is endemic to New Zealand. It has been observed near Lake Ohia, Pairatahi, Hamilton, Cambridge, Wellington, and Napier.
