Diagnosis.
(See also the identification key of incerta subgroup, section 3.4. 2.). This species can be distinguished from the other known members of the incerta subgroup by the combination of the following characters of the male and female genitalia: tegumen with small peniculi; vinculum u-shaped at the outer margin with a large sized saccus, rectangular; sacculus with a narrow and short apical extension, curved inwards, strongly club-shaped; juxta large, the inferior plate shaped like a rounded triangle produced into a sharp point, the sides rounded, the superior plate broad and short, shortly bifid terminally; phallus short and thick; vesica with a small semi-circular flat cornutus; ventrolateral plates of female segment A 8 very large, trapezoidal, the anterior side triangle-shaped, as long as wide; ostium bursae large, funnel-shaped, sclerotized, with pointed tip on each side, ductus bursae with two narrow posterior sclerotized areas, at least 10 times longer than wide.
Description.
(Fig. 7 M – P). The general shape of the female forewing is more elongated than that of the male; wing patterns similar in both sexes, but males are generally darker. Also, the ground colour of the forewing is variable from cartridge-buff to dark ochraceous according to the specimens, however most available specimens are rather ochraceous. Antenna ochraceous, serrate in the male, filiform in the female, flagellum adorned dorsally with buff scales in both sexes; palpus brown; eyes dark brown. Head and thorax covered with long light ochraceous hairs. Abdomen buff heavily suffused with fuscous scales. Forelegs light brown, otherwise ochraceous suffused with fuscous scales. Forewing ochraceous suffused with brown and fuscous scales; three more or less distinct dark brown spots, one antemedial, one at apex of cell and one postmedial; a more or less distinct longitudinal fuscous fascia along lower margin of cell, partly within, partly without cell from base of cell to the subterminal line; one subterminal line with brown elongated markings on the veins; outer margin adorned with brown spots between the veins, fringe ochraceous heavily suffused with brown and fuscous scales, basal line of fringe light ochraceous. Hindwing white extensively suffused with fuscous scales over its entire area, veins suffused with brown scales, four more or less visible brown elongated markings on the veins, fringe concolor (white), basal line of fringe buff. Underside of forewing ochraceous, heavily suffused with brown and fuscous scales over its entire area but more heavily in the medial area, fringe ochraceous heavily suffused with fuscous scales, in males; underside of forewing pale ochraceous slightly suffused with brown and fuscous scales, lore heavily in the costa, fringe ochraceous suffused with fuscous scales, in females. Underside of hindwing white suffused with brown scales, particularly in costal and apical areas, outer margin adorned with more or less visible brown spots between the veins, fringe concolor (white). — Forewing length: male 26–33 mm (x ̅ = 29.1 mm, N = 13); female 27–35 mm (x ̅ = 32.5 mm, N = 13). — Male genitalia (Fig. 8 D, O). Tegumen with small peniculi; vinculum u-shaped at the outer margin and w-shaped at the inner margin without indentation, with a large saccus, rectangular. Valve with sacculus and cucullus separate; costa short and narrow, heavily sclerotized, ending with a stout and short straight spine, with two apical teeth; sacculus heavily sclerotized rounded at base, a narrow and short apical extension, curved inwards, strongly club-shaped, bearing numerous short and stout spines; cucullus longer than sacculus, weakly sclerotized, slightly clavate at apex, with scattered and papillated hairs; juxta large and conical, the inferior plate shaped like a rounded triangle produced into a sharp point, the sides rounded, the superior plate broad and short, shortly bifid terminally; uncus angled and stout at base, narrowed in distal part, pointed at apex, tufted with long hairs on upper side; phallus short and thick, a bit curved in the middle; lamina ventralis with an elongate carinal crest, produced into paired lateral lobes; vesica with a small semi-circular flat cornutus. — Female genitalia (Fig. 9 D). Apophyses anteriores with spatulate tips; ventrolateral plates of segment A 8 very large, sclerotized, trapezoidal, the anterior side triangle-shaped, as long as wide; ostium bursae large, funnel - shaped, sclerotized, with pointed tip on each side; ductus bursae long and narrow, with two posterior sclerotized areas at least 10 times longer than wide; corpus bursae pyriform, without signa; ovipositor lobes at least 2.2 times longer than wide with dorsal surface bearing numerous short and stout setae, the ventral side of each lobe slightly curved; apophyses posteriores more slender than apophyses anteriores. — L 5 instar larva (Fig. 5 G). Length 30–35 mm, width 4.0 mm; head smooth, orange brown, prothoracic shield light brown, body with ground colour pearl yellow, pinacula and caudal plate light brown. Young larvae are similar in appearance to mature ones.
Etymology.
Named after Kamba, the name of the tribe who live in the southern part of the Eastern Province in Kenya; treated as a noun in apposition.
Distribution.
Ethiopia, Kenya, Mozambique, Tanzania and Uganda. Known from many localities in different vegetation mosaics (‘ East African coastal Zanzibar-Ihambane’ (Mosaic # 16 a), ‘ Somalia-Masai acacia- Commiphora deciduous bushland and thicket’ (Mosaic # 42), ‘ East African evergreen bushland and secondary acacia wooded grassland’ (Mosaic # 45)) (White 1983) (Fig. 10) belonging to the Congolian, Ethiopian and Zambezian bioregions (sensu Linder et al. 2012).
Ecology.
Larvae were collected from young stems and shoots of 17 host plants (Table S 4) belonging to the following genera: Andropogon L., Cenchrus, Chloris Sw., Digitaria, Hyparrhenia, Hyperthelia Clayton, Megathyrsus, Panicum, Setaria, Snowdenia C. E. Hubb., Sorghum Moench and Sporobolus growing in grasslands. It should be noted that 70 % of the larvae were collected on Megathyrsus maximus (1414 larvae reared from this host plant and found in 80 of the 131 collection sites for this species), which suggests that S. kamba shows a preference for this host plant.
