Diagnosis. Coleophora nyanzaensis   is ochre with white streaking along the veins. The male genitalia do not resemble those of any other known species due to the robust rounded protuberance in the ventral corner of the sacculus and the small protuberance in the dorsal corner. The phallotheca is also characteristic, with one of the two juxta rods harpoon-shaped.

Description. Wingspan 10–11 mm. Head white, slightly suffused ochre dorsally. Antenna white; scape without erect scales. Labial palpus white on inner side and brown on lower part of outer side; second segment about twice as long as third. Proboscis normal, slightly longer than labial palpus. Thorax and tegula white, slightly tinged with ochre. Forewing ochre, white streaked more evident along costa, anal fold, and dorsum; costal fringe ochre, dorsal fringe light ochre-grey. Hindwing light grey with light ochre-grey fringe. Abdomen dirty white.

Male genitalia ( Figs. 56–58 View FIGURES 56–59 ): Gnathos knob globular. Tegumen stout, narrow in middle, pedunculus slightly dilated outside. Transtilla thin and elongated, slightly curved. Valvula small, curved on ventral edge. Cucullus short, narrower at base. Sacculus strongly curved on ventral edge with a robust rounded protuberance on ventral corner and a short and thin protuberance on dorsal corner. Phallotheca with two juxta rods, shorter curved and pointed at apex, longer terminating in shape of a harpoon. Cornuti short, consisting of an elongated structure with numerous small spines.

Female genitalia: Unknown.

Abdominal structures ( Fig. 59 View FIGURES 56–59 ): No posterior lateral struts. Transverse strut slightly curved and thicker on distal edge. Tergal disk about 5 times longer than wide, covered by about 25 spines.

Bionomy. The early stages and the foodplant are unknown.

Distribution. The species is known from Uganda and Tanzania.

Etymology. The name derives from the word Nyanza, which in the Kyniarwanda language refers to Lake Victoria, because the collection sites are part of the region surrounding the lake.
