Figs 1‒2

Material. Holotype, male, Nigeria, Kajela , 7.vi.1974, leg. Dr. Politzar (MSW, slide: MSW 2015/24 Coss).

Description. Male. Antenna short (3 times shorter than fore wing), bipectinate, setae 2 times longer than antenna rod diameter. Length of fore wing 14 mm. Fore wing relatively short, with bluntly rounded apex, brown, with black thin wavy lines from postdiscal area to outer margin of wing, dense black transverse strokes from wing base to postdiscal area and from costal magrin to medial trunk. Hind wing light-brown without pattern. Fringe brown, unicolorous.

Male genitalia. Uncus long, apically beak-like; gnathos arms long, thick; gnathos compact; valve of medium length, apically blunt, poorly developed strongly sclerotized crest on costal margin closer to apex; transtilla process very long, uncinately bent, apically acute; juxta strongly sclerotized, with very long lateral processes diverged at right angle; saccus semicircular, small. Phallus slightly shorter than valve, straight, with poorly extended distal end, apex obliquely cut, vesica aperture in dorso-apical position, about 1/4 of phallus, vesica without cornuti.

Female unknown. Diagnosis. The new species differs from G. minettii , G. timora and G. zhiraph in the poorly developed pattern on the fore wing (in the species listed above, there are bright developed brown portions on the fore wing postdiscally and submarginally, and the pattern of thin black lines is more developed). Externally, the new species is closer to G. konkistador from Southern Sudan, which also has poorly modified pattern on the fore wing, but has a significant difference from it in the male genital structure: the crest on the costal edge of the valve is poorly developed (in G. konkistador the crest is robust), the valve is apically blunt (in G. konkistador the apex of the valve is narrowing and semicircular), the lateral processes of the juxta are diverged at a right angle (in G. konkistador the lateral processes of the juxta are diverged at an acute angle).

Etymology. Mungo Park (1771–1806) was a Scottish explorer of West Africa. After the exploration of the upper Niger River around 1796, he wrote a popular and influential travel book titled Travels in the Interior Districts of Africa in which he theorized the Niger and Congo merged to become the same river. He was killed in the modern territory of Nigeria during the second expedition, having successfully traveled about two-thirds of the way down the Niger.
