Treatment

Phalaena limbaria Fabricius, 1775, Syst. Ent. 624, Anglia [England].

Geometra conspicuata [Denis & Schiffermüller], 1775, Ankündung syst. Werkes Schmett. Wienergegend: 316, [Germany, Hesse: Frankfurt am Main]. Syntype(s) from the collection Gerning (Frankfurt a. M., 1745-1802). The taxon limbaria s. str. is not recorded from Vienna; in Lower Austria and in neighbouring Moravia only the taxon roraria occurs.

Ph [alaena] Geom [etra] auroraria Hübner, [1787], Beitr. Gesch. Schmett. 1 (2): 27, pl. 4, fig. Y, 1, 2. According to Scoble (1999) it is a synonym both of limbaria and roraria : Hübner’s figures clearly show that it is limbaria .

Phal [aena] Geom [etra] circumdataria Villers, 1789, Linn. ent. 2: 330, pl. 6, fig. 10, Europe, Gallia [France].

Phalaena Geometra conspicuaria Borkhausen, 1794, Natur. eur. Schmett. 5: 465, Europe.

Geometra spartariaria Hübner, [1799], Samml. Eur. Schmett. 5 Geometrae (1): pl. 22, fig. 116, Europe.

Ph [alaena] Geom [etra] conspicuaria Esper, [1801], Die Schmett. 5 (5): 124, pl. 24, figs 5-7, Syntype(s), [Germany, Hesse]: Frankfurt am Main, Darmstadt; Switzerland; Hungary [patria falsa?]. Junior primary homonym of conspicuaria Borkhausen, 1794. Synonym of roraria according to Scoble (1999) and Skou and Sihvonen (2015); the syntypes were identified by Hacker (1999) as I. limbaria limbaria ; the same author designated as paralectotype a male from the Esper collection (ZSM Munich) and as lectotype one from the Gerning collection (LMW Wiesbaden). In Hungary only the taxon roraria occurs.

Fidonia limbaria ab. quadripunctaria Fuchs, 1899, Jb. nassau. Ver. Naturk. 52: 150, [Germany], [Rhineland-Palatinate]: Loreley district [infrasubspecific: each wing with black discal spot].

Fidonia conspicuata ab. fumata Mathew, 1907, Entomologist’s Rec. J. Var. 19: 21, [England]: Suffolk [infrasubspecific].

Fidonia limbaria ab. nigricaria Bubacek, 1915, Verh. zool.-bot. Ges. Wien 65: (109), [France], Pyrénées-Orientales: surroundings of Vernet-les-Bains 2200 m [infrasubspecific].

Fidonia limbaria var. infuscata Thierry-Mieg, 1916, Miscnea. ent. 23: 50, Europe [infrasubspecific].

Fidonia limbaria f. nigrostriata Heydemann, 1938, syn. n., Ent. Z. Frankf. a. M. 52 (3): 23, pl. 1, figs 21, 22, [Germany]: southern Holstein [infrasubspecific]. Valid at subspecies rank according to Scoble (1999); however, according to the original description it co-exists with f. quadripunctaria ["it appears here in a percentage up to almost 45% among the quadripunctaria Fuchs"]; also Lempke (1952) considers it an individual form, frequent in the Netherlands.

Isturgia limbaria f. postnigrescens Lempke, 1952, Tijdschr. Ent. 95: 208, Netherlands: Harendermolen, Nijmegen, Roermond, Steenwijk, Winterswijk, Montferland, Veenendaal [infrasubspecific: "hind wings unicolorous blackish"].

Isturgia limbaria f. postclara Lempke, 1952, Tijdschr. Ent. 95: 208, Netherlands: Wehl, Tilburg [infrasubspecific: "hind wings as clear as the fore wings"].

Isturgia limbaria f. postdemarginata Lempke, 1952, Tijdschr. Ent. 95: 208, Netherlands: Roermond [infrasubspecific: "hind wings without the dark marginal band"].

Material examined.

Spain: 1 ♂, 1 ♀, Aragon: province of Huesca, Fanlo, 1.vi.2007, Perez leg. (RCCF). Belgium: 1 ♂, 1 ♀, Comblain[-au-Pont], 14.v.2000, Evrard leg. (RCCF). Germany: 1 ♂, 1 ♀, North Rhine-Westphalia: Wuppertal 12.v.2006, Hager leg. (RCCF); 1 ♂, Thuringia: Treffurt, Eichsfeld, ex l. 12.ix.1992/2.iii.1993, E. Friedrich leg. (RCEF) (digital images of both sides on Lepiforum). Switzerland: 1 ♂, 1 ♀, Valais: district of Sierre, Val d’Anniviers, 1.vii.2005, Chapelle leg., (RCCF).

Colour images of specimens from Great Britain are shown in Ford (1972: pl. 29, figs 13-15): from Ipswich in England (upperside and underside) and from Achanalt in Scotland (upperside).

Diagnosis

(Figs 3 View Figures 3–12 , 8 View Figures 3–12 , 13 View Figures 13–17 , 18 View Figures 18–22 ). Dark terminal fascia almost always well developed on the four wings. Hindwing often densely covered with dark scales, sometimes unicolorous blackish. Hindwing underside more or less densely covered with dark scales, except the whitish radiating streaks.

In the female genitalia signum small (0.7-1 mm). Bullae tympani with a roundish lobe (visible only in one bulla in a female from Spain).

Distribution.

Great Britain (Scotland and eastern England, now extinct), part of Germany (cf. Skou and Sihvonen 2015: map on page 97), Benelux, France (excluding the southern Alps), northern Spain (eastern Aragonese, Andorran and Catalan Pyrenees). Our specimens from Valais confirm the occurrence of the species in Switzerland, where only old records existed (cf. Reser 2010).

Remarks.

According to Skinner (1984) the specimens from Ross-shire (Scotland) are larger and paler than those from southern England; the difference is also evident in the images in Ford (1972).
