Translation of the original description:

89. Lithocoiletis [sic] helianthemella m.—f. 115.

[According to my analytical table it is near L. acerifoliella , but certainly different from it. The pattern on the forewing does not consist of 3 golden, “broken” transverse bands, edged on both sides with black and basally coloured golden, but of 4 black chevrons which do not reach either the costa nor the dorsum; in the apex a black transverse line and a black dot.

The larva mines in September and early October on the underside of Helianthemum vulgare , mainly the larger leaves, in rocky, shadow-rich localities near Regensburg. It is 2” long; yellow, with faint green transparent gut; with single, fine hairs; head and first 3 legs brownish; head black, last abdominal segments brown; ventral side yellow with central row of brown dots (shining gut canal). In mid-September or October it makes an oval, flat, whitish spinning on a leaf in which it pupates after a few days before hibernating; from 29 larvae only 1 made its cocoon inside the mine.

The larva of the summer generation is full-grown at the end of June and the adult emerges mid-July; only this have we reared thus far, and moreover just 1 specimen, but we await more in springtime (Ottm. Hofmann).]

Lectotype designation. Gottlieb August Wilhelm Herrich-Schäffer (1799–1874) was an occasional insect dealer of mainly Lepidoptera , who sold insects either directly or sometimes via Zoologische-Mineralogische Verein Regensburg. His private collection via Otto Staudinger and Andreas Bang-Haas was sold in parts and can be found in the following museums: 1) via the collection of O. Staudinger to the Museum für Naturkunde der Humboldt-Universität, Berlin; 2) via the collection of M. J. Bastelberger to the Zoologische Staatssammlung, Munich; 3) via the collections of O. Hofmann and Th. Walsingham to the Natural History Museum, London (Horn & Kahle 1935–1937). Five specimens (3 males and 2 females) were found in the collection of ZMHB which belonged to the collection of Staudinger, and were identified as ‘ helianthemella ’ and were collected and reared in Regensburg without indication which specimen is the name bearing type. We believe that these five specimens were originally collected by Gottlieb August Wilhelm Herrich-Schäffer and sold to Otto Staudinger ( Figs 11–15 ). The phenotype of the male specimen bearing the label of the genitalia slide TRB3935♂ most closely resembles the original description. Therefore, we designate it as the lectotype ( Fig. 11 ).

Here we designate the following male specimen as the lectotype of Lithocolletis helianthemella Herrich-Schäffer, 1861 :

♂, [1]‘Rgsbg.’[handwritten]; [2]‘ex coll. Staudinger’; [3] genitalia slide TRB3935♂, in ZMHB ( Figs 11 , 17 ). Paralectotypes: 2♂, 2♀:

♂, [1] ‘Regensburg’ [handwritten]; [2] ‘ex coll. Staudinger’; [3] genitalia slide TRB3945♂, in ZMHB ( Figs 12 , 18 ) ♂, [1] ‘Regensb’. [handwritten]; [2] ‘ex coll. Staudinger’, in ZMHB ( Fig. 13 ).

Remarks: the sub-triangular shape of the distal half of valva in the male genitalia is variable within the type series ( Figs 17, 18 ).

♀, [1] ‘Regensburg’ [handwritten]; [2] ‘ex coll. Staudinger’, in ZMHB ( Fig. 14 ). ♀, [1] ‘Regensburg’ [handwritten]; [2] ‘ex coll. Staudinger’, [3] ‘Coll. Led.’, in ZMHB ( Fig. 15 ).
