Diagnosis. Anomologa dispulsa is externally a rather variable species, but has a predominantly white forewing with a narrow, irregularly shaped medial fascia and a distinct black spot at the forewing apex. The forewing color and pattern in combination with the light-grey to white hindwing are characteristic ( A. hobohmi is darker, more greyish-black, with the medial fascia broad, joining in middle with subapical dark pattern; its hindwings are dark grey). Male genitalia are characterized by the sacculus having a distinct medial ridge, with a straight or weakly medially directed ventral margin, moderately long saccus that slightly extends anteriorly even with or not reaching the pedunculus, and comparatively short phallus (2/3 length of valva) with a short subapical tooth (in A. hobohmi the sacculus has a distinctly pointed apex, the saccus extends well beyond the pedunculus, and phallus as long as valva with large triangular subapical tooth). Female genitalia with thick and apically inflated apophyses anteriores, whereas apophyses posteriores are slender (both apophyses are dilated distally in A. hobohmi , or slender, not dilated apically in A. terminata sp. nov.).

Redescription ( Figs 3–5 View FIGURES 2–11 , 14, 15 View FIGURES 12–19. 12–17 ). Wingspan 19–24 mm. Head light brown, frons yellow, labial palpus light brown mottled with dark brown. Antennal scape and flagellum light brown. Thorax and tegulae white mixed with brown. Forewing white, basal fascia subtriangular, narrowing towards dorsal margin, medial fascia slender, interrupted in middle, subapical fascia slender, oblique, narrowed from costal margin to tornus, termen black, apical streak distinct, fringe white, brown tipped; hindwing covered with white, brown-tipped scales, fringe light grey.

Male genitalia ( Figs 21–23 View FIGURES 20–27 ). Uncus lobes elongate, ovate, extends to 2/3 length of valva; tegumen subrectangular in basal 1/3, then trapezoid shaped, anteromedial emargination triangular, extending to 1/3 length of tegumen; valva gradually broadened through 3/4 length, apex rounded; sacculus twice as broad as adjacent part of valva, subovate, with distinct medial ridge, apex with short pointed tip, extends to 1/3 length of valva; vinculum slender, band-shaped; juxta lobes rounded, separated by slender V-shaped incision; saccus subrectangular, extending anteriorly slightly beyond pedunculus; phallus length 2/3 length of valva, narrowed in middle on one side, subapical tooth short.

Female genitalia ( Fig. 28 View FIGURES 28–30 ). Papillae anales subtriangular, slightly longer than segment VIII, densely covered with short setae in distal half, top of ovipositor broad, densely granulated; apophyses posteriores slender, slightly longer than segment VIII; segment VIII subrectangular, about 2.5 times broader than long, tergum evenly sclerotized, sternum deeply emarginated posteriorly, well sclerotized laterally and along anterior margin; subostial plate rounded; apophyses anteriores thick, distinctly broadened at the top, 1/2–1/3 length of segment VIII; ductus bursae and corpus bursae unknown (most likely have been dissolved during maceration).

Biology. Hostplant and larval stages unknown. Adults have been collected from November to February.

Distribution. Namibia and South Africa.

Remarks. Anomologa dispulsa was described based on single male collected in Slypsteendrift, Limpopo Province, South Africa. The species from Brandberg mentioned as “Genus 9, spec. 1” ( Bidzilya 2007: 117, figs 59–61; 271: pl. 9, fig. 62) is identified here as A. dispulsa .
