Acalyptris pyrenaica
Diagnostic description:Diagnosis. A. pyrenaica is characterised by the complete black colour, which separates it from most other European Nepticulidae; it only slightly resembles some Parafomoria species, but these usually with at least some white scaling. The male genitalia resemble other species in this group, but A. pyrenaica has a double uncus and simpler, narrow valva.
Morphology:Description Male. Forewing length 2.0–2.5 mm, wingspan 4.0–5.6 mm. Head: frontal tuft and collar dark grey to anthracite black; scape black with some white scales along frontal edge, forming very small eyecap; flagellum grey, antenna with 36–39 segments. Thorax and forewing dark grey to anthracite black, at forewing tip paler bases of scales are more exposed, yielding speckled appearance. Underside dark grey. Hindwing completely grey on both surfaces, costal bristles present. Abdomen completely black, conspicuous long anal tufts mixed pale grey with black.
Female (from original description). Wingspan 5.l mm, antenna with 33 segments. Further as male.
Male genitalia. Measurements: see Table 3. Vinculum with narrow ventral plate. Tegumen forming blunt pseuduncus. Uncus with several setae laterally and complex sclerotized tip: a posterio-dorsal bilobed element and more ventrad blunt element. Gnathos with narrow, relatively long central element. Valva slender, with almost parallel margins, with slight inner bulge at basis; near tip with many setae. Transtilla with distinct transverse bar and relatively short sublateral processes. Aedeagus distally widened, with pair of dorsolateral carinae, each split in 2–4 points; ventral carina with short distal points, wide apart. Vesica without any cornuti.
Female genitalia. Probably incomplete in slide. Short anal papillae. Apophyses anteriores and in particular posteriores long. Ductus spermathecae with 2 convolutions. Corpus bursae not seen.Associations:Unknown, all adults were taken by sweeping grassland vegetation in May to July. The habitats were limestone grassland in the Eifel mountains and a mountain pasture in the Pyrenees. The hostplant cannot belong to the Plumbaginaceae; although a species of Armeria is present in the type-locality, it does not occur in the German localities.
Distribution:Only known from Spain, Pyrenees and Germany, Eifel.
Citation:This taxonomic description is based on Van Nieukerken (2007).
