Diagnosis. Elachista bazaensis is a unicolorous white or pale yellow species. It is very close to E. vartianae, which is larger and more narrow-winged. Their male genitalia are similar to each other, and the length of the digitate process appears to be the only difference: it is longer than the juxta lobes in E. vartianae, shorter than the juxta lobes in E. bazaensis. Female genitalia are characterized by the short ductus bursae that is only about 3 times as long as apophyses posteriores.
Molecular characterization. The analyzed six specimens of E. bazaensis showed a maximum variability of 0.15 %. Average distance between the specimens was 0.05 %. The genetically closest species was E. vartianae with 7.44 % minimum distance to E. bazaensis.
Redescription. Wingspan 9–11 mm. Labial palpus fuscous white, length 1.2 times diameter of head. Head, neck tuft and thorax fuscous, scape of antenna varying from white to brownish grey, pedicel and flagellum grey. Foreleg inwardly leaden grey, legs otherwise ochreous white except spurs of hind legs that are ochreous grey. Forewing ground colour varying from nearly white to pale yellow with concolorous fringe, base of costa narrowly black. Hindwing pale grey, fringe along anterior margin darker grey, otherwise concolorous with wing colour. Underside of wings grey with creamy white with conclorous fringe, except along anterior margin darker grey.
Male genitalia. Uncus lobes broad, 1.5 times as long as wide at their widest point, sickle-shaped, mesial margin convex, apex pointed, lateral margin concave. Spinose knob of gnathos oval-shaped. Valva nearly 1.5 times as long as tegumen + uncus, 4.5 times as broad as long, parallel-sided; cucullus elongate. Digitate process tongue-shaped, 0.2 times as long as valva, medially and distally with stout setae. Juxta lobes devoid of setae, somewhat laterally produced, mesial and distal margin rounded without distinct limit. Phallus 0.75 times as long as valva, bent, basally broad, gradually tapered toward pointed and reinforced apex; basal opening posteriorly oriented, caecum absent; one small cornutus with oval and plate-shaped part and apically directed small spine, the cornutus sometimes absent.
Female genitalia. Apophyses posteriores slender, straight, twice as long as papillae anales. Apophyses anteriores about half the length of apophyses posteriores. Ostium bursae invaginated in sternum 8, narrow; colliculum as wide as ostium bursae, with elongate lateral sclerotzations; distance between ostium bursae and inception point of ductus seminalis 1.5. times as long as apophyses anteriores; ductus bursae + colliculum about 3 times as long as apophyses posteriores, tubular, widest in its posterior third, membranous, anterior half granulose, with longitudinal foldings, incepted in corpus bursae with distinct border; corpus bursae fairly small, oval-shaped, with small internal granules in median area; signum rather short, dentate, boomerang-shaped. Biology. Unknown.
Distribution. Spain.
