A species with forewing shades of ochreous and a light line along the costa. Judging from the structure of the genitalia it belongs to the Palearctic group of Coleophora vulnerariae Zeller, 1849 (23rd speciesgroup of Toll’s system). The male genitalia resemble those of C. semicinerea Staudinger, 1859 , and the female genitalia those of C. christenseni Baldizzone, 1983 , with obvious differences. This is the only Afrotropical Coleophora species of which we know the foodplant and the larval case. Description. The original description of the adult as given by Meyrick is correct: “Male and female. 15-16 mm . Head, palpi and thorax whitish, second joint of palpi with moderate rough apical tuft. Antennae white ringed with fuscous, basal joint with moderate tuft of rough projecting scales along anterior edge. Abdomen pale silverygrey, anal tuft whitish. Forewings very narrowly lanceolate, long-pointed, acute; yellow-ochreous, tinged with brown on costal half; a slender white costal streak from base to 4/5, edged beneath with fuscous suffusion continued to apex; submedian fold suffused with whitish towards base; cilia light grey. Hindwings and cilia grey”. ( Meyrick, 1920b: 91 ). Male genitalia ( Figs. 83–86 ): Gnathos knob ovular. Tegumen stretched. Pedunculus rounded. Transtilla small, curved. Valvula large, rounded, indistinct. Cucullus long, slender, slightly wider at apex than at base, apex rounded. Sacculus rounded, with curved fold at inner margin; a small sclerotized turned-down tooth at dorso-caudal angle. Phallotheca conical, tapering into an acute sclerotized apex. Cornuti: some tiny spines. FIGURES 83–87.

Female genitalia ( Figs. 88–90 ): Papillae anales ovular. Apophysis posterioris about 1.5 times longer than anterioris. Sterigma subtrapezoid, longer than wide, deeply excavated towards ostium bursae. Ostium bursae square. Colliculum cup-shaped, with medial line, gradually narrowing into ductus bursae. First segment of ductus rather straight, with sclerotized medial band enveloped in a sleeve speckled with tiny spikes, about 5 times longer than sterigma; second segment transparent, gradually merging with sack-like corpus bursae. Signum small, leaflike. Abdominal apodemes ( Fig. 87 ): No posterior lateral struts. Transverse strut with convex distal margin, medially thinner, proximal margin convex, medially thickened. Tergal disk about 2.5 times longer than wide, covered with about 30 tiny spikes. Bionomy. Several larvae were collected on the seedheads of Trifolium semipilosum Fresen.The plant belongs to the family Fabaceae and is widespread in Eritrea , Ethiopa, Kenya , Tanzania , Malawi , Uganda and Yemen . There is no information on how the larva feeds or how the case is constructed, but it is probable that the larva feeds on the seeds and constructs a case out of a flower and silk. The case of the specimen mentioned above was collected on 16.X.1998 and the adult emerged on 31.X.1999 .The larval case ( Figs. 12, 13 ): 7 mm ., red-brown, cylindrical, roughly covered with fragments of the foodplant. Anal opening tri-valved. Oral opening at about 30° to 45° to length axis. Distribution. Kenya , Tanzania and eastern Congo .
