contents <p><b><i>Silba ungulifera</i> McAlpine, 1964</b></p><p>(Figs 34–37)</p><p>Originally described, but not illustrated, by McAlpine (1964: 709) on the basis of the holotype male and two females collected at Antongil, Maroantsetra, 20–25. iii.1958, by B. Stuckenberg. The holotype was deposited in the Museum National d’Histoire Naturelle, Paris, but when contacted as part of the research for this paper they were not able to locate the specimen. However, based on the description of the very distinctive male genitalia by McAlpine (1964) it is possible to attribute specimens to this species.</p><p>Additional notes on the male terminalia: Posterior margin of surstylus at base of cerci with 2 large, posteriorly directed processes arising from a common, raised, setulose base. Each process with 2 very strong talon-like apical spines, outer spine approximately 0.3× size of the inner. Phallus partly bi-segmented, short and stout with spicules apically and on outer margin of basal section. The male genitalia are figured here for the first time (Figs 34–37).</p><p><b>Material examined:</b> 1♂ Ambohitra, Joffreville, 800 m, 9–12.iv.1991, A. Freidberg & F. Kaplan (SMNHTAU); 1♂ Maroantsetra, ix.1959, J. Valdon; 4♂ Maroantsetra, 1962, J. Valdon (RBINS).</p>
