Locris johannae var. nigrolimbata Lallemand, 1910: 47 (description)

Note.

When Lallemand (1910) described the species Locris johannae (from the southwest bank of Lake Tanganyika ) he described as well a variety Locris nigrolimbata from Madagascar. According to article 45.6.4 of the International Code of Zoological Nomenclature ( ICZN 1999), Locris johannae nigrolimbata should be regarded as a subspecies (Fig. 4 ). This subspecies supposedly differs by the colouration of the tegmina. Locris j. johannae has completely red tegmina while L. j. nigrolimbata bears some black at their apex ( Lallemand 1910). Our studies of material from Tanzania and Kenya, showed that the specimens with the black apex tegmina have the same male genitalia as the holotype of L. j. nigrolimbata while the specimens with the entire red tegmina have different male genitalia. This led us to consider L. j. nigrolimbata as a valid species and here change its rank to L. nigrolimbata comb. nov. However, we remain for now with only one specimen of this species from Madagascar, the other specimens were collected on the African continent .

Distribution.

Madagascar and eastern Africa

Description of the male terminalia

(Fig. 5 ). Pygofer (Fig. 5A ), in lateral view, dorsal margin straight and perpendicular to anterior margin, posterior margin generally convex. Aedeagus consist of two parts, first basal part, representing 3/4 of total length with a base elbow shaped before widening ventrally then curving up dorsally and narrowing into a tubular structure almost of same thickness to its regular rounded dorsal apex; second part, hanging from first, its width is regular for most of its length with apex in shape of a swan, neck oriented posteriorly (Fig. 5B ). Parameres prolonged apically by two little structures, inner one curved into a spine and external one rounded (Fig. 5C ). Subgenital plates wide at base then abruptly narrowing in a long filament shape curved downward at its apex (Fig. 5D ).

Body length: 8-10.5 mm.
