GENUS BASEODISCUS DIESING, 1850 View in CoL View at ENA

Polia Delle Chiaje, 1822 View in CoL in Delle Chiaje (1822–29) (see Remarks below); not Polia Ochsenheimer, 1816: 73 (Lepidoptera) .

Baseodiscus Diesing, 1850: 243 View in CoL ; type species Polia delineata Delle Chiaje, 1822 , fixed by monotypy.

Taeniosoma Stimpson, 1857: 162 View in CoL ; type species not fixed (either Taeniosoma aequale Stimpson, 1857 or Taeniosoma septemlineatum Stimpson, 1857 View in CoL ).

Eupolia Hubrecht, 1887: 10–11 View in CoL ; type species Polia delineata Delle Chiaje, 1822 , fixed by original designation.

Balanocephalus Kennel, 1891: 282 View in CoL ; type species Balanocephalus pellucidus Kennel, 1891 View in CoL , fixed by monotypy.

Nematodemus Graff, 1899: 513 View in CoL ; type species Nematodemus lumbricoides Graff, 1899 View in CoL , fixed by monotypy.

Diagnosis: Given by Gibson (1994: 114). An additional feature is the proboscis musculature consisting of inner circular, middle diagonal, and outer longitudinal layers ( Magarlamov & Chernyshev, 2011).

Remarks: The publication year of the generic name Polia Delle Chiaje is 1822 rather than 1825 (e.g. Gibson, 1995: 475) or 1827 (e.g. Neave, 1940: 844) as previously regarded, in accordance with Article 12.2.7 of the Code ( ICZN, 1999); the type species has not been fixed. The name Polia Delle Chiaje was first used for the following six nominal species, originally appearing as captions for plates supposedly published in 1822, while the written descriptions for these species were supplied in Volume 2 (issued in 1825 or 1827) (see Remarks for Baseodiscus delineatus below) or Volume 3 (issued in 1828): Polia caerulescens Delle Chiaje, 1822 (pl. XLIII, fig. 9) (description in Volume 3 as ‘ P. cilestra ’: 172–173); Polia delineata Delle Chiaje, 1822 (pl. XXVIII, fig. 4) (description in Volume 2 as ‘ P. lineata ’ on p. 409 and as ‘ P. delineata ’ on pp. 427–428; the specific name also appears on p. 444 in the explanations for plates); Polia geniculata Delle Chiaje, 1822 (pl. XLIII, fig. 10; LXXVIII, figs 5, 6) (description in Volume 3: 177); Polia oculata Delle Chiaje, 1822 (LXXVIII, fig. 8) (description in Volume 3: 172, 177; the name also occurs on p. 181 in the explanations for plates); Polia punctata Delle Chiaje, 1822 (pl. LXVIII, figs 7, 11) (description in Volume 3, as ‘ P. punteggiata ’ on p. 172 and ‘ P. punctata ’ on p. 177; the name also occurs on p. 181 in the explanations for plates); and Polia siphunculus Delle Chiaje, 1822 (pl. XXVIII, figs 1–3) (description in Volume 2, as ‘ P. sipuncolo ’ on pp.406–408 and ‘ P. sipunculus ’ on p. 427). However, these complications do not overturn precedence of the senior homonym Polia Ochsenheimer, 1816 ( Lepidoptera : Noctulidae) over Polia Delle Chiaje, 1822 .
