Dacus (Lophodacus) kurrensis sp.n.

Figures 78 – 83 .

Diagnosis. Differs from D. seguyi in having a red-brown (fig. 78) rather than black scutum, and a deeper costal band (fig. 83).

Description. Size. Small, wing length, 5.7 mm. Head (fig. 80). Pedicel+first flagellomere not longer than ptilinal suture. Face, antennal furrow with a dark spot; ovate, slightly taller than broad. Frons, frontal setae 2, orbital setae 1. Thorax (figs 78, 81). Scutum predominantly red-brown, with indistinct fuscous areas pre- and postsuturally either side of mid-line; postpronotal lobe yellow; notopleural callus yellow; notopleural xanthine wedge shaped (connected to notopleural callus); lateral and medial postsutural vitta absent. Scutellum without any dark patterning (except for basal dark margin). Anepisternum with a narrow yellow stripe from notopleural callus to katepisternum; extended onto katepisternum. Laterotergal xanthine confined to katatergite. Thoracic setae. Anterior notopleural seta present but reduced (thin black on left side; thin white on right side); anterior supra-alar seta absent. Wing (fig. 83). Basal cells bc and c without an almost complete covering of microtrichia; cell bm without microtrichia; narrow subbasal raised section of cell br with extensive covering of microtrichia, apically confined to anterior two-thirds. Crossvein R-M beyond middle of cell dm. Costal band complete; shallow, only slightly extending below vein R2+3 before wing apex; apically expanded into a spot which reaches about one-third depth of cell r4+5. Anal streak absent. Cells bc and c hyaline. Without any crossbanding. Legs (fig. 82). Femora bicoloured, yellow basally; fore- and hindfemur red-brown in apical third; midfemur red-brown in apical half. Abdomen (fig. 79). Predominantly red-brown; tergite II yellow apically; tergite III indistinctly fuscous basally. Tergites I – V all fused. Male. Unknown. Female. No data (aculeus retracted and not dissected).

Etymology. Geographic name meaning from Kurra Falls, Nigeria.

Material. NIGERIA: Holotype female, Plateau State, Kurra Falls, 60km s.e. Jos, 5 – 7.xii.1987, F. Kaplan ( TAU).

Remarks. In the absence of a male it is impossible to place this species with certainty. It is similar to D. acutus sp.n. but differs in the shallower costal band and lack of dark abdominal markings.
