Hydroptila moxica sp. nov.

( Figs 4, 5 )

Material examined. Holotype male: [CAW 764Z, slide], ANGOLA, Moxico Province, Cuando River, Site 8— Cuando campsite bridge, light trap, -13.607, 19.53235, 02/xi/2016, I.S. Ferreira.

Diagnosis. Hydroptila moxica s hows close resemblance to H. maoae and, similarly, groups with H. aegyptia with which it shares the Y-shape form of the ventral plate in the male genitalia. It is distinguished from H. maoae by the sharp right-angled spine on the tip of the phallus and the almost quadrate basal section of the ventral plate and more abruptly formed narrow posterior extension of the ventral plate which is more gradually tapered in H. maoae .

Description. Male. Length of each forewing 1.6 mm (n = 1). Head: antennae damaged, flagellomeres almost square in profile, bearing abundant sensilla placodea on flagellomeres; scent organs visible beneath occipital lobes on dorsal head. Genitalia: Abdominal segment IX with short lobes at apicolateral angles; dorsal plate (segment X) elongate, slightly exceeding length of inferior appendages, round apically; ventral plate in ventral view broadly ‘Yshaped’ with basal half almost quadrate, sharply narrowed to slender distal projection; inferior appendages elongate, rod-shaped, equal width throughout length in ventral view, broader basally in lateral view, with sharp dorsal spur at apex; phallus with median fine titillator and sharply right-angled spine apically.

Etymology. The name ‘ moxica ’ refers to the type locality.

Distribution. Known only from type specimen from Moxico Province of eastern Angola.
