(Fig. 4)
Holotype ♂ (GP Wf 5436) “ KENYA | Lake Naivasha | Fisherman camp | 20-II-1989 | 1900 m | leg. R. Schouten 85”, “shore with Acacia trees | at light”, ex coll. Wf, coll. Bldz.
Paratype: 1 ♀ (GP Wf 5437) idem, ex coll. Wf, coll. Bldz.
Diagnosis. This species has a characteristic appearance due to the colour of the forewing: light ochre, shaded brown at the apex and along the dorsum and with a spot in the cell. The male genitalia are different from all the known species on the basis of the undifferentiated cucullus, the large triangular valvula, the glomerulus-shaped protuberance in the dorsal corner of the sacculus, the short phallotheca, and the length of the two cornuti. The female genitalia are similar to those of some African species, many of which have not yet been described. The most distinguishing feature is the sclerotized central part of the colliculum.
Description. Wingspan 10 mm. Head and antennae light ochre, scape without erect scales. Labial palpus light ochre on the inner side and brown on the outer side; the second segment about 0.5 times longer than third. Proboscis very short, almost vestigial. Thorax and tegula light ochre. Forewing narrow, light ochre, tinged with brown at base of dorsal fringes and along dorsum; small, brown, oval spot in cell; costal fringes light ochre, dorsal fringes brown. Hindwing light grey, fringes light ochre. Abdomen pale ochre.
Male genitalia (Fig. 18): Gnathos knob globular. Tegumen broad, medially constricted, pedunculus dilated externally. Transtilla narrow and elongated. Valvula very large, triangular, outer margin curved. Cucullus short, not clearly separated from valvula. Sacculus small, with an oblique outer edge, in dorsal corner a rounded protuberance covered with short blunt spines. Phallotheca short, cylindrical, sclerotized only on outer margins; vesica long and robust with two very long, needle-like cornuti.
Female genitalia (Figs. 19, 20): Papillae anales large, length about twice their width. Apophysis posterioris about twice that of apophysis anterioris. Sterigma elongated trapezoidal, curved on proximal edge. Ostium bursae oval. Colliculum cup-shape, restricted in center, sclerotized in distal part and at sides of the ostium. Ductus bursae short, not sclerified. Bursa copulatrix round, without signum.
Note: The genitalia preparation was performed without separating the genitalia from the abdomen, and furthermore it was not cleaned of frustules present in various parts. Unfortunately its condition does not allow a new preparation.
Abdominal structures (Fig. 19): No posterior lateral struts. Transverse strut slender, slightly curved in middle. Tergal disk about 6 times their width, covered by 18–20 conical spines.
Bionomy. The early stages and the foodplant are unknown.
Distribution. The species is known only from Kenya.
Etymology. The species name is a patronym for its collector, Dr. Rob T. A. Schouten, Head of Department Collection and Production of MUSEON, Museum of Science and Culture, The Hague, Netherlands.
