Morphological diagnosis.

Batrachedra confusella sp. nov. (Fig. 3 ) and B. pinicolella (Fig. 4 ) cannot be separated externally with certainty though it is remarkable that none of the 56 specimens of B. confusella with images in BOLD has a spot at about the one-third the length of the forewing fold, a character commonly present in B. pinicolella . All 47 specimens of Norwegian dissected or barcoded specimens of B. confusella sp. nov. are without the spot on the fold. In eight of 20 dissected or barcoded Norwegian specimens of B. pinicolella the spot is present. Thus, the presence of the spot in the fold strongly indicates that the actual specimen belongs to B. pinicolella . With a wingspan of 11.0-12.0 mm, B. pinicolella is slightly larger than B. confusella sp. nov. on average. In the male genitalia we found a diagnostic character in the shape of the valva and the uncus. On average B. pinicolella (Fig. 7 ) has a longer and more slender valva than B. confusella sp. nov. (Fig. 5 ). The uncus is slightly different in the two species in shape and width. In B. confusella sp. nov. the lateral sides are smoother and with finer and longer setae than in B. pinicolella . In B. pinicolella the uncus is laterally distinctly rugose with coarse setae. The tip of the phallus in B. confusella sp. nov. (Fig. 6 ) is armed with a distinct cornutus. In B. pinicolella (Fig. 8 ) the cornutus is narrower and often will appear merely as a fold inside the phallus. The gnathos tends to be broader distally in B. pinicolella than in B. confusella sp. nov. In the female genitalia, the two species differ in the length of the signum. In B. pinicolella (Fig. 10 ) the signum is in the range 290-380 μm. In B. confusella sp. nov. (Fig. 9 ) the length of the signum ranges from 490 to 600 μm. In B. pinicolella the sclerotized portion of the ductus bursae is narrower and straighter than in B. confusella sp. nov. Fig. 22 of the female genitalia given by Koster and Sinev (2003) represents B. pinicolella in the present interpretation of the name.

Molecular diagnosis.

Sequences of B. pinicolella and B. confusella sp. nov. form two well-defined clusters which received separate Barcode Index Numbers (BIN-codes): AAF0078 and AAF0077 respectively. The DNA barcode region of B. confusella sp. nov. shows 0.95% intraspecific divergence and a minimum divergence of 6.82% to its closest relative B. pinicolella (Fig. 11 ). The latter species shows no intraspecific variability in our material (the slight apparent variation in the neighbor-joining tree results only from variation in sequence lengths). Therefore, DNA barcodes allow safe identification of the two species. The 407-bp long fragment of the nuclear MDH gene differs by 5.8% from that of B. pinicolella . The 506-bp long fragment of EF-1a differs by 3.1% from that of B. pinicolella . Therefore, both examined nuclear genes support the status of the two species and permit their identification by these markers as well. All examined five specimens were infected by Wolbachia , while none of the specimens of B. pinicolella were infected, suggesting a difference between the two species also in this regard.

We generated a genomic dataset from nine individuals of B. pinicolella using ddRAD sequencing. We obtained 1.24 million reads per individual on average after quality filtering steps. After clustering 88% sequence similarity, we recovered 19,292 clusters per sample were retained with an average of 82.26 per sample for cluster depth (Table 1 ). A total length of ddRAD data is 926,224 bp, of which 9,242 are single nucleotide polymorphisms (SNP). Phylogenetic analysis using SNP data produced robust support for the relationship between the individuals (Fig. 12 ). The two revealed lineages corresponding to B. confusella sp. nov. and B. pinicolella , which have 100% bootstrap support. STRUCTURE also identified two genetic clusters (Fig. 11 ).

Description.

Male (Fig. 3 ). Wingspan 10-11 mm. Labial palp 2.3 times diameter of eye, cream, porrect, slightly curved, second segment longer than third, outer side with brownish suffusion, third segment on outer side with two bands. Head cream, with appressed scaling. Antenna glabrous, with appressed scales, pale ochreous brown, weakly ringed, rings becoming more distinct distally. Thorax ochreous yellow. Forewing ochreous yellow, with scattered dark brown scales, denser distally and on costa, discal spot small; cilia brownish grey; hindwing grey, cilia grey. Legs cream, inner sides with brownish suffusion, which on tarsi forms bands. Abdomen cream, with lateral grey suffusion.

Female. Externally similar to male.

Male genitalia (Figs 5 , 6 ) Uncus gradually narrowed towards tip, slightly concave at two-thirds length, medially with lateral setae, lateral margins smooth, with fine hairs; gnathos gradually narrowed, becoming parallel-sided before distal end, distal end spinose; valva nearly parallel-sided, dorsal margin curved distally, costa angled or slightly hooked at distal end; anellus lobes rounded; phallus long and slender, sub-distally with bulge, cornutus near distal end distinct, tapered proximally.

Female genitalia (Fig. 9 ) Papillae anales broad with short setae; apophyses posteriores and anteriores of similar length, apophyses anteriores with basal fork; antrum funnel-shaped with medial ridge; ductus bursae with medial portion sclerotized and curved, anterior portion with two or three coils; corpus bursa with long (490-600 μm) and oval signum; signum with numerous short, transverse ridges.

Etymology.

The species’ name, Batrachedra confusella , indicates the confusion with its sister species, B. pinicolella .

Biology.

Due to the confusion of the two species, the biology is insufficiently known. Batrachedra confusella sp. nov. is the well-known species affecting Pinus , and it has been found in several localities of pure pine forests. However, a female beaten from an artificial afforestation of Larix at a lowland locality in Switzerland without Pinus in the nearby surroundings (Bryner in litt.) also belongs to B. confusella sp. nov., indicating that Larix may be an additional host-plant. Batrachedra pinicolella , in contrast, seems to be restricted to forests of Norway spruce ( Picea abies ), which is considered to be the host-plant. This hypothesis is proved by a dissected Finnish female specimen bred from Picea .

Bolov and Sinev (1990) recorded outbreaks of B. pinicolella on Picea orientalis , P. abies , P. pungens , Abies sp. ( “European”), A. nordmanniana , and less frequently on Pinus sp. ( “eastern”), P. silvestris , and P. pityusa from the Kabardino-Balkaria republic in northern Caucasus. Possibly both species were involved.

Distribution.

The species pair B. confusella sp. nov. and B. pinicolella is widely distributed in Europe but seems to be absent from the Mediterranean (http://www.faunaeur.org; accessed on 25.iv.2021). However, as former records have been summarized among the latter taxon, a detailed study of distribution of both species is required for future studies. From our sequenced and/or genitalized material, B. confusella sp. nov. together with its major hostplant, Pinus sylvestris , is distributed in the temperate zones between the Alps in the South and Fennoscandia in the north. Batrachedra pinicolella in concordance with its major host-plant, Picea abies , shows a boreo-montane distribution pattern with isolated records from the Alps and mountainous areas of Central Europe as well as northern and north-western Europe. A barcoded specimen of B. confusella sp. nov. from Armenia (coll. ZMUC) confirms the presence of this species in Caucasus. According to images of genitalia on the mothdissection.co.uk website, both species are present in the United Kingdom (https://mothdissection.co.uk/species.php?Tx=Batrachedra_pinicolella; accessed on 30.iv.2021)
