Hypotrabala lunda Takano & László, 2024 View in CoL , Ecologica Montenegrina View in CoL , 72, 42. Type locality: “ ZAMBIA 1147m / Lukwakwa, West Lunga NP., / (Cryptosepalum forest/Dambo) / 12°39’40”S, 24°26’13”E ”. HT: ♂, GS LG 6313 (African Natural History Research Trust).

Note on distribution ( Fig. 1 View Figure 1 ). The species was described based on two males from one locality in Zambia . We examined additional material that expanded the distribution area to Zimbabwe and the DRC.

Description of hitherto undescribed morphologic features. Male ( Figs 10, 13–15 View Figures 10–15 ). The head ( Fig. 34 View Figures 33–35 ). The frontoclypeus does not bear any outgrowths. The eyes are naked. The maxillary palpus is very short. The labial palpus is three-segmented, with the proximal segment about two times smaller than the medial one and the distal segment about five times smaller than the medial one. The antenna bipectinate consists of 54–55 flagellomeres. The rami are densely covered with short sensilla chaetica, which rapidly elongate in the proximal one-seventh of the antenna and then rapidly shorten in the apical one-seventh. The legs ( Fig. 34 View Figures 33–35 ). The tibial spur formula is 0-2-2; the epiphysis is about the length of the longest rami, approximately 1.9 mm. Note on vesica. In the original species description, Takano & László (2024) mentioned that the left longitudinal serrated plate on the vesica is twice as long as the right one. That is not visible on the photos of the phallus they provided ( Takano & László 2024, Fig. 85). In our preparations (n = 4), both plates are of equal length ( Figs 31–34 View Figures 27–32 View Figures 33–35 ), but other features are similar to the original description. Female ( Figs 11–12 View Figures 10–15 ). Reminiscent of the male in coloration, but overall larger, has approximately 4.5 times shorter rami and the epiphysis of 0.4 mm ( Fig. 35 View Figures 33–35 ), and a dark brown discal spot instead of the silverish one. Forewing length 27–32 mm. The genitalia ( Figs 36– 37 View Figures 36–39 ). The papilla analis is somewhat oval, densely covered with chaetae, and ventrobasally, near the base of the posterior apophysis, has a wrinkled, sclerotized area. The posterior apophysis is about one-third longer than the anterior one. The sterigma is heavily sclerotized and shield-like, with an anterior cup-like extension near the ostium, which is hidden with a beak-like outgrowth, and lateral arms about half of the sterigma’s length. The ductus bursae is heavily sclerotized, semioval, and flat, about two times smaller than the bursa copulatrix. The bursa copulatrix is membranous, somewhat pear-shaped, and dorsomedially bears a small transversal plate-like signum with lateral minute dents. Wing pattern and coloration variability. The forewing background color varies from yellow ( Fig. 14 View Figures 10–15 ) to orange ( Fig. 15 View Figures 10–15 ) in males, and dark speckles and dark-colored areas may be more ( Figs 12, 15 View Figures 10–15 ) or less intense ( Figs 11, 14 View Figures 10–15 ) in both sexes.
