Elachista griseifrons Sruoga & Kaila, 2026, sp. nov.

Elachista griseifrons sp. nov. Figs 1 D, E, 3 A – D, 4 E Material examined. Holotype. Ethiopia • ♂; Addis Ababa; 8.9506°N, 38.8256°E; 1–3 Feb. 1974; H. Silfverberg leg.; gen. prep. VS 627; MZH. Diagnosis. Elachista griseifrons externally closely resembles E. silfverbergi, known from the same locality, but it differs in a more grey frons and longer labial palpus compared to the width of the head. Also, the male genitalia are very similar to those of E. silfverbergi. However, the digitate process is reduced to a bluntly triangular lobe in E. griseifrons, whereas in E. silfverbergi it is well developed and about twice as long as in E. griseifrons. Description. Male. (Fig. 1 D, E). Forewing length 3.9 mm; wingspan 8.4 mm (N = 1). Head: frons whitish-grey, vertex greyish-brown intermixed with whitish-grey, some scales with darkened tips, neck tuft greyish-brown; labial palpus 1.75 times as long as width of head, whitish-grey above and greyish-brown below; scape, pecten, and flagellum brownish-grey. Thorax dark grey-brown, tegula grey-brown. Forewing: strongly mottled with scales basally off-white and distally grey-brown; wing slightly darker beyond middle; antemedian transverse fascia blurred, incomplete, present as small, greyish-white spot at fold, small costal and tornal spots blurred, greyish-white; fringe brownish-grey. Hindwing and its fringe brownish-grey. Female. Unknown. Male genitalia (Fig. 3 A – D). Uncus lobes widely apart from each other, longer than wide, broadest before middle, tapered distally, setae on ventral surface dense, scale-like near apex and along lateral margin, becoming longer and thinner in mediobasal part. Socius with a few long setae. Spinose knob of gnathos large and rounded, as large as width of uncus lobe at its widest point, proximal margin shortly pointed. Valva long and narrow, about four times as long as wide at costal hump; basal fold of costa extended to 1 / 2 of valva, beyond it with small, broad hump; cucullus long, slightly bent towards costa. Median plate of juxta with a pair of large dorsally directed lateral pockets. Juxta lobes large, separated from each other with shallow incision; median margin straight, joining straight distal margin at right angle, distal margin convex, ventral surface distally with long setae. Digitate process glabrous, reduced to a small, bluntly triangular lobe. Vinculum V-shaped, saccus not prominent. Phallus about 0.7 as long as valva, straight, caecum small, apex acute and curved to form strongly sclerotized hook; ventral surface with band of proximally directed small spines in apical 1 / 3; vesica without cornuti. Biology. Unknown. Flight period. The single specimen was collected in early February. Distribution. So far, this species is known only from central Ethiopia. Etymology. From the Latin griseus, meaning “ grey ” and frons, meaning “ forehead ”, in reference to the grey forehead of the moth. The name is a noun in apposition. Remarks. The forewings of this specimen are somewhat abraded. Therefore, the description is approximate.
