Pseudophilotes fatma

On 20-IV-2024, A.A. photographed a male Pseudophilotes fatma (Fig. 2A) mud-puddling on soil at Djebel Refaa (35°32'19.3"N, 5°51'46.4"E; 1,696 m asl), Province of Batna, northeastern Algeria. Subsequently, on 18-V-2024, E.B. photographed another male specimen (Fig. 2B) nectar feeding approximately 4 km north of the first location (35°34'27.1"N, 5°52'53.8"E; 1,675 m asl). Both observation sites are meadows within Atlas cedar forests, where the species’ larval host plant, Salvia argentea, is present (Fig. 2C). Both localities are subject to significant overgrazing (Fig. 2D). Climatic data for these localities, extracted from the WorldClim database at ~ 1 km ² resolution (Fick & Hijmans 2017), indicate that both sites fall within the superior semi-arid Mediterranean bioclimatic zone, characterised by cold winters and a mean annual precipitation of 500 mm. The new locality records are situated approximately 35 km northwest of the type locality and 15–18 km west of the nearest most recently confirmed locality, Col de Telmet in the Belezma Biosphere Reserve (Fig. 3). The latter locality was reported in the literature (Tennent 1996; Tolman & Lewington 1997), based on an original record by the French lepidopterist Guy Barragué (pers comm. to J.T.). Part of Barragué’s collection is currently housed at the Muséum des Sciences Naturelles d'Angers, France (MHNAn), although it remains the property of the “Groupe d'Information de Recherche et d'Animation sur les Zygaenidae ” (GIRAZ) (Benoît Mellier, pers comm.). This collection includes several unvouchered specimens of P. fatma from Algeria and Morocco (see Tab. 1), including the aforementioned specimen collected from Col de Telmet in 1953 (Fig. 4). This specimen represents the most recent known record of P. fatma in Algeria prior to our observations, indicating a 71-year gap in the species’ records for the country. Newly reported occurrences of P. fatma indicate minimal changes to its known range, as they fall within the IUCN species distribution range (van Swaay et al. 2015). The updated distribution map (Fig. 3) suggests that although the IUCN inferred limits of P. fatma in Algeria encompass the entire Aurès Mountains range, the actual current distribution of the species appears to be more restricted, confined primarily to the western part of the Aurès Mountains, within Batna Province. In Morocco, the species is predominantly found in Ifrane Province, with fewer occurrences reported in Khénifra, Midelt, and Séfrou. ......Continued on the next page Tarrier (2020) reported that Fatma’s Blue has become extinct in several localities in Morocco and is endangered in others (Tab. 1). In Algeria, the status of the species remains uncertain in most localities and it may be extinct in the Belezma Biosphere Reserve, where recent targeted surveys failed to detect its presence (Berkane et al. 2019). In this study, newly identified localities for the species fall outside protected areas, rendering them vulnerable to threats such as livestock overgrazing (Fig. 2D). The precarious conservation status of P. fatma necessitates immediate conservation actions. These should include the implementation of area-based management plans in historical distribution sites to prevent further decline and ensure the species’ persistence. The bulk of Oberthür’s collection is now in the NHM, London, and contains a long series of fatma including, judging from the labels, many reared by the French lepidopterist Guy Barragué in France. The two specimens provided to Oberthür by Staudinger are among these specimens. Oberthür (1890: 19) did not designate a type specimen; we here formally designate and illustrate a lectotype, and recognise a paralectotype, as follows: Lectotype ♂ (Figs. 5A–C), with the labels (1) handwritten “ Lycaena Bavius - Fatma Obthr. Etud. d’Ent. XIIIe livon pl. 7. Fig. 50 Djebel Aurès (Staudinger) 1887”; (2) printed / handwritten “John Tennent Butt. of Morocco, Algeria & Tunisia Pl. 11 Fig. 53”; (3) red-bordered, circular, printed “Type”; (4) printed “Lectotype: Lycaena Bavius var. Fatma Oberthür, 1890 (designated by Bouam & Tennent, 2024)”; (5) purple-bordered, circular, printed “Lectotype”. Paralectotype ♂ (Figs. 5D–F), with the labels (1) handwritten “ Lycaena Bavius - Fatma Obthr. Etud. d’Ent. XIIIe livon pl. 7. Fig. 51 Djebel Aurès (Staudinger) 1887”; (2) yellow-bordered, circular, printed “Paratype”; (3) printed “Paralectotype: Lycaena Bavius var. Fatma Oberthür, 1890 (designated by Bouam & Tennent, 2024)”; (4) blue-bordered, circular, printed “Paralectotype”.
