Barcode Index Number:-

Protasis glitzella Staudinger, 1883 . Stettin Ent. Ztg., 44 (4-6), 185

Type locality: SPAIN: Granada. Lectotype [here designated]: “Lectotypus 1” [red label], “Lectotypus n 9. 1 Pleurota glitzella Stgr. Lvovsky det.”, ”Granada m[ich] 80” [pale blue label], “Origin.” [pink label] ( MFNB, examined from photographs and barcode: DNA sample MFNLEP246, 658 bp [250n]) .

Material studied: SPAIN, ALMERÍA, Sierra de los Filabres, route Purchena-Senés , 1600 m, 1 1 (GP 5637 J. Tabell, DNA sample 25437 Lepid Phyl [barcoding failed]), 16-VI-2007, Jan Sumpich leg. & coll. The species was not treated by Back (1973) .

Diagnosis: A small species, characterized by very short 3 rd palpomere of labial palpus, which is concealed by hairy scales, and long cilia in the forewing with two distinct dark, broad, and slightly concave fringe lines. In the male genitalia, the shape of gnathos, valval lobe and strongly concave outer margin of cucullus distinguish P. glitzella from other species. The female is unknown.

Molecular diagnosis: An old lectotype was sequenced successfully, resulting in a 658 bp DNA sequence [250n]. It exhibits 97.26 % similarity with the sequence of a Spanish still undetermined Pleurota species (n=3, private records).

Description: Adult (faded to brown, originally greyer). Wingspan 11-13 mm (original description). Labial palpus white to pale brownish white above, 3 rd palpomere not visible. Antenna pale brown. Head, thorax and tegula white. Forewing white, dorsal third covered with pale brown scales, blackish brown discal, discocellular and plical spots distinct; no costal line; subcostal line broad, brown, mixed with white. Fringe line V-shaped, formed of blackish brown scales, cilia long, white, with two distinct brown lines, lines slightly concave at dorsal area. Hindwing and cilia pale brown. Abdomen slightly lustrous, pale grey, each segment with a transverse row of ochre scales.

Male genitalia: Uncus triangular from ventral view, lined with several long bristles. Gnathos fluke-shaped from ventral view, tapered towards apex, moderately short, 1.3x length of uncus, surfaced with small nodules medially. Valva upwards oblique; cucullus narrow, ventral margin medially concave, costa slightly bulged basally; valval lobe club-shaped, basally slightly bulged, apical half surfaced with several nodules and short bristles. Anterior extension of juxta straight and narrow, posterior lobe very long, with a small apical tooth. Vinculum U-shaped. Phallus curved, parallel-sided, with a robust plate-shaped cornutus and a long loose bundle of numerous spiniform cornuti.

Female genitalia: Unknown.

Biology: Unknown.

Distribution: Southern Spain.

Remarks: The designation by Lvovsky is unpublished, and according to the ICZN (1999, Article 74.7) it is not valid. Consequently, one original specimen is designated herein as a lectotype.
