Genus Ugandatrichia Mosely, 1939

Ugandatrichia Mosely, 1939 , 36, Kenya. Type species: Ugandatrichia minor Mosely , by original designation. Moselyella Kimmins, 1951, 195–196. Type species: Ithytrichia violacea Morton , by original designation and monotypy. Synonymized by Schmid (1960).

Ugandatrichia: Marshall, 1979 , 195, 198–199.

Adult. Head with pairs of large ellipsoidal dorsal setal warts, gently curved long dorso-lateral warts and small round postero-lateral warts; antennae usually long, 30–37 segments, ocelli 3. Maxillary palpi 5-segmented, 2 basal segments short, other segments cylindrical, apical segment longest; labial palpi 3-segmented, basal segment short, other segments cylindrical. Pronotum with pairs of round mesal warts and round lateral warts; mesoscutellum diamond-shaped.

Wings relatively broad but still long and acuminate as typical of the Hydroptilidae , forewings with apical forks II and III and often discoidal cell, hindwings with apical forks II, III and V and often discoidal cell, crossveins often indistinct, forewings with dense dark setal coverings and sometimes with oval patch of creamcoloured scalelike hairs (androconia according to Hsu & Chen 2002). Spur formula 0, 3, 4.

Male with pair of long, membranous eversible processes (scent organs) arising laterally between tergite and sternite of segment II in some species. A small semi-membranous ventral process present in both sexes, on sternum VII in male and sternum VI in female.

Male genitalia. Segment IX well developed, variously with dorsal and ventral posterior and anterior excisions; segment X variable in development, from bearing median lobe and lateral processes to difficult to discern; inferior appendages large, broad and elongate in some species, bifurcate at apical half in some species, with few spurs mesally or meso-dorsally in some species, without superior or inner lobes; phallus slender, with distinct proximal and distal regions, divided by constriction adjacent to spiral titillator.

Female genitalia. Known for few species. Sternite VII with diagnostic patch or row of setae in some species; sternite VIII with sclerotized process or some other distinctive marking.

Final instar larva. Known for few species. Cylindrical or flattened dorsoventrally. Head dark. Thoracic legs short and stout. Abdominal segments I to VII with some tergal and pleural sclerites, presence and shapes of sclerites appearing to be species specific.
