Diagnosis. Prorostrum distinctly narrowing apicad, measured in its mid-length in ♂ 0.90 ×, in ♀ 0.80 × as broad as metarostrum ( Figs. 190, 192 View FIGURES 187–199 ). Third elytral interval between middle and posterior two-thirds raised to form low rib evidently higher than neighbouring intervals ( Fig. 194 View FIGURES 187–199 ), the rib ending abruptly at small yellowish patch of integument. Spermatheca as in Fig. 228 View FIGURES 212–228 .

The remaining characters as in the above genus description.

Remarks. Variation. The only specimen from Western Cape (Wilderness) differs from locotypical series in the much larger basal lightening of elytra, fully encompassing humeral calli and elytral base, and extending apicad as a uniform triangular yellowish fleck, narrowly contiguous with the median crescentic mark along the sutural interval. It is not distinct from the series from Port St. Johns in the shape of rostrum, and it shares the presence of an elevated rib on the 3 rd elytral interval. Further material from the most southern part of the area of L. crinalis   is necessary to shed more light on the taxonomic relevance of this difference in colour pattern.

Biology. In the locus typicus (Port St Johns: Silaka Reserve) this species was recently collected in numbers from flowering Apodytes dimidiata   , while practically absent from non-flowering trees. This suggests its development occurs in generative parts of the plant, but it has not yet been confirmed by direct observations and the preimaginal stages await discovery.

Distribution. South-eastern R.S.A. (Eastern Cape, Western Cape) ( Fig. 294 View FIGURES 289–296 ).
