Diagnosis.

Cochylimorpha callosana is externally characterized by an extensive and conspicuous straw-yellow reticulate pattern with a scattered admixture of brown scales, and yellowish white spots of ground colour which are indistinct and of irregular size and form. In the male genitalia the tegumen has convex margins and a long terminal process; the valva is wide; the median process of the transtilla is long and wide with concave margins and a truncated apex; the caulis has deep ventro-lateral folds; and the phallus is ventrally curved at about 30 degrees with a latero-basally attached and ventrally curved cornutus, about ½ as long as the phallus. In the female genitalia the papillae anales are lanceolate and densely covered with short setae; the apophyses are stout; the ductus bursae is short; and the corpus bursae is long with the signa posteriorly consisting of a large sclerotized plate and in the median part of the bursa with a large group of thorns.

Molecular data

(Fig. 36 ). BIN URI: BOLD: ADI 3050 . The intraspecific divergence of the DNA barcode region is 0.15 % (n = 2). The minimum distance to the nearest neighbour, C. dorsimaculana , is 3.12 %, to C. perfusana 3.13 %, to C. bucegiana sp. nov. 4.43 %.

Habitat.

Dry and stony open hilly meadows and semi-open mountain slopes on limestone substrate, from 350 to 1500 m.

Biology.

Poorly known. Adults fly in the daytime ( Mann 1854: 576) and evening ( Mann 1857: 165). The most recently collected specimens were taken in the evening and early morning by net, usually around places where Centaurea ( Asteraceae ) species grow, but some specimens were also attracted to light (J. Junnilainen personal observation). Moths are on wing from mid-May to mid-June.

Distribution

(Fig. 48 ). Widespread in the north-western part of the Balkan Peninsula ( Croatia and Slovenia) and north-eastern Italy, localized in eastern France (Prémanon), and known only from historic records from Corsica ( France) and Hungary. The type locality is Rijeka (formerly Fiume) in north-western Croatia ( Herrich-Schäffer 1856: 157). Razowski (1970: 162; 2002: 43; 2009: 37) erroneously gives Lower Austria: Schneeberg or only Austria as the type locality of the species, but these records refer to C. perfusana ( Herrich-Schäffer 1851: 183) .

We examined voucher material from north-western Croatia (Rijeka; Velebit Mountains: Velebitski, Baške Oštarije, 1100 m; Istria: Mt. Maggiore), south-western Slovenia (Nanos; Senožeče; Kozina; Komen), north-eastern Italy (Trieste; Trentino; Friuli; Udine), Corsica and Hungary (Budapest, Csillebérc, as Jambory). These are the first country records for Slovenia and Hungary (for explanations see below). Further material was identified from figures in the literature or available on the world wide web (all as C. perfusana unless otherwise mentioned): Yugoslavia without further details ( Razowski 1987: 250 figs 70–72, 313 figs 562–563 as Stenodes perfusana ; 2001: 37; 2002: 43, pl. 5 fig. 91, pl. 47 fig. 91; 2009: 37, pl. 9 fig. 97, pl. 40 fig. 97); north-eastern Italy (Monte Bondone, Viotte, 1500 m; Val. Venzonassa, Malga Confin; Trieste, Basovizza, 440 m) ( Klimesch 1951: 24; P. Huemer in BOLD and pers. comm.; R. Bryner in Lepiforum as Phalonidia acutana ( Kennel, 1913)) ; Hungary (Budapest) ( Fazekas 1994: 40 fig. 1); and the first record from mainland France (Prémanon, 26. v. 2022) (G. Mainguy in iNaturalist).

Literature records.

The earliest record of the species, which predates Herrich-Schäffer’s (1856: 157) formal description, is from Gradischa in the historic southern Carniolia (= Krain in German) by Mann (1854: 576 as Cochylis Callosana Mihi. [probably Mtzn., error during digitalization]). This historic locality name currently is known as Gradisca d’Isonzo in the north-eastern part of modern Italy. Another record, which also predates the formal description, is given by Mann (1855: 552 as Cochylis Callosana Mann i. l. H. S.) from Corsica (Lazareth peak on the road from Ajaccio to Tavaco). There are two historic voucher specimens labelled as Corsica, one in ex coll. O. Staudinger in MfN, Berlin (Viola Richter pers. comm.) and another in ex coll. A. Caradja in MGAB, Bucharest (M. Stănescu pers. comm.). Molecular studies of recently collected material from Corsica will be necessary for the certain identification. Mann (1857: 165) recorded it from Fiume (= Rijeka) in Croatia. According to Staudinger and Wocke (1871: 242), the species is distributed in southern Carniolia and Corsica ( France), both repetitions of the data of Mann (1854: 576; 1855: 552). Kennel (1913: 284) mentions Corsica ( France), southern Carniolia, Istria, Dalmatia ( Croatia) and Wallis ( Switzerland). The first two are repetitions of the previous references. We examined voucher material from Croatia, but we cannot confirm the record from Wallis because the studied figures of adults from Switzerland posted on different websites all proved to be C. perfusana (see above).

Klimesch (1951: 24) recorded it as Euxanthis callosana HS. from Italy, Trentino, Monte Boldone, Viotte, 1500 m, this is the highest recorded elevation for the species. It has been reported from Hungary by Gozmány (1968: 277 as Stenodes callosana HS ) without further data. Subsequently, two historic specimens collected from Budapest (Jambory = Csillebérc, Zs. Bálint pers. comm.) and deposited in ZSM were recorded as C. perfusana by Fazekas (1994: 40). Later the species was also mentioned in the checklists as C. perfusana , from the first ( Szabóky et al. 2002: 68) to the latest ( Pastorális and Buschmann 2018: 135), but recently the two historic specimens deposited in ZSM have been ignored, and the species deleted from the Hungarian checklist by Fazekas (2022: 118; 2023: 24, 28). In Razowski’s works (1970: 163; 2001: 37; 2002: 43; 2009: 37, all as C. perfusana ) only records from Italy and Croatia (Dalmatia) are of C. callosana . Trematerra (2003: 51) recorded C. perfusana from northern Italy, but the data from north-eastern Italy (Friuli-Venezia Giulia) refer to this species, the other records need re-examination (for details see C. perfusana above). The record of C. perfusana f. callosana from Romania (Bucegi Mountains) by Kovács and Kovács (2005: 61, 64 fig. 53, 70 fig. 72, 87, 88) was erroneous and is of C. bucegiana sp. nov. Lesar and Godevič (2010: 77) list C. perfusana from Slovenia based only on two old literature sources, Mann (1854) and Staudinger and Wocke (1871), however, as we already demonstrated above, all these historic records under the name C. callosana refer to modern Italy. The latter authors mention also C. perfusana , but from Serbia. As a consequence, all of these data for C. perfusana and C. callosana are not part of the Slovenian fauna. Glerean et al. (2022: 60 as C. perfusana ) published data from the Prealpi Giulie Natural Park (Gruppo del Monte Plauris) in Friuli, north-east Italy. We were not able to examine the voucher specimens, but we presume that the record may refer to C. callosana , because all of the specimens examined from north-eastern Italy proved to belong to the latter species.

As a consequence, confirmed data of C. callosana are recorded herewithin for the first time from the Slovenian fauna as the previous records refer to Italy. The species also replaces C. perfusana in north-eastern Italy, and the records from north-western Italy require re-examination ( Trematerra 2003: 51; Stoch 2003). We report C. callosana again from Hungary as recently Fazekas (2022: 118; 2023: 24, 28 all as C. perfusana ) deleted it from the checklist, claiming lack of evidence.

Taxonomic notes.

Cochylis callosana was described based on an unspecified number of specimens from Fiume (currently Rijeka in Croatia) by Herrich-Schäffer (1856: 157) in the sixth volume of his Systematische Bearbeitung der Schmetterlinge von Europa as a species related to C. perfusana (“ Der Perfusana am nächsten, ... ”), the latter species was mentioned in the fourth volume ( Herrich-Schäffer 1851: 183). Also in the sixth volume, but in the Index of the fourth volume, both species were mentioned and both cross-referenced to the same page: “ * callosana ( Cochylis ) Mtzn. pp. 183 ” and “ ** perfusana ( Cochylis ) FR. p. 183, HS 247, 248 ” ( Herrich-Schäffer 1856: Index 7, 32). These similar references have probably been the starting point of the subsequent confusion and taxonomic problems, because at the specified page, 183, there is only the description of C. perfusana .

Two arguments support our presumption that the name C. callosana might be a commonly used manuscript name before the Herrich-Schäffer’s formal description. In the Index of the fourth volume, Herrich-Schäffer (1856: 7) mentions “ Mtzn. ” (= Metzner) as the author of the species name, and the second is that Mann (1854: 576; 1855: 552) twice used the name callosana to record a well-defined moth from southern Carniolia and Corsica before the description of the species by Herrich-Schäffer (1856: 157). Cochylis callosana was defined by Herrich-Schäffer (1856: 157) as having a short forewing, straw-yellow coloured markings with only two black spots on the forewing, neither on costal margin nor on termen (remarks: the black spots are the scattered spots formed by the admixture of brown scales). All these characters fit the material examined in this study from Croatia, Slovenia, Italy, France and Hungary. It has also been treated as a valid species, Phalonia callosana HS. , by Kennel (1913: 283–284, pl. 12 fig. 85). Kennel’s description also fits the original one, except for the figure which, as mentioned by Kennel himself, is too light yellow (“ Taf. XII, fig. 85 ♂ (zu hochgelb) ”) ( Kennel 1913: 283); however, this feature characterizes worn specimens. This species has also been treated by Klimesch (1951: 24) as Euxanthis callosana HS. In the monograph on the Palaearctic Cochylini, Razowski (1970: 38, 162, colour pl. 8, pl. 50, pl. 127) mentions a lectotype deposited in MfN Berlin, but incorrectly gives Schneeberg in Lower Austria as the type locality. Neither the lectotype nor the paralectotype possesses locality data. Razowski confused and synonymized C. callosana with C. perfusana , and gave the reference as: “ Cochylis callosana Herrich-Schäffer, 1851 , Systematische Bearbeitung der Schmetterlinge von Europa 4: 183 ”, however, this is wrong and in fact it refers to C. perfusana . The correct reference is: Cochylis callosana Herrich-Schäffer, 1856 , Systematische Bearbeitung der Schmetterlinge von Europa 6: 157 (different year, volume and page), where Fiume (= Rijeka, Croatia) is specified as the type locality. Razowski figured two male adults, one of C. perfusana and another of C. dorsimaculana (as perfusana f. dorsimaculana), and the genitalia of both sexes of C. perfusana . In his subsequent works Razowski (2001: 13; 2002: 43; 2009: 37) continues using the incorrect data and taxonomic status, and figures the adult male of C. perfusana , the female of C. dorsimaculana , and the genitalia of both sexes of C. callosana , all under the name C. perfusana .

The reasons why Cochylimorpha callosana ( Herrich-Schäffer, 1856) , sp. rev. is reinstated to species rank are:

the divergence in the DNA barcodes: the DNA barcoded specimens cluster in a separate BIN (BOLD: ADI 3050 ), at a minimum distance of 3.12 % to the nearest neighbour C. dorsimaculana , at 3.13 % to C. perfusana and 4.43 % to C. bucegiana sp. nov.

the different external morphology: straw-yellow reticulate pattern with scattered admixture of brown scales and grey hindwing characterizes C. callosana , in contrast to the olive-green reticulate pattern without an admixture of brown scales and the light grey hindwing of C. perfusana .

the clear differences in the structure of the genitalia of both sexes: the male with slightly concave margins and truncated apex of the median process of the transtilla and ventrally curved phallus of C. callosana , in contrast to C. perfusana male with a parallel sided and tapering apex of the median process of the transtilla and straight phallus; and female with a long corpus bursae and signa consisting of a large sclerotized plate posteriorly with weak longitudinal folds and in the middle of bursa a large group of tiny thorns of C. callosana , in contrast to C. perfusana female with a short corpus bursae and the signum being a very weakly sclerotized plate in the posterior 1 / 3 of the bursa, with distinct longitudinal folds.

the clear differences in the habitat and distributional pattern: C. callosana inhabits meadows at lower elevations (from 350–1500 m) and is widespread only in the north-western Balkan Peninsula and north-eastern Italy, and is local in eastern France, Corsica and Hungary, in contrast to the montane meadows (between 550–2100 m) of the mountain ranges inhabited by the even more widely distributed C. perfusana , from the Carpathians and the Pirin Mountains through the Austrian Alps and Switzerland to the Hautes Alpes in France.
