The South American genus Diapontia is revised to include nine species: Diapontia uruguayensisKeyserling, 1877 (= Diapontia senescens Mello-Leitão, 1944 syn.n.; D. infausta Mello-Leitão,1941 syn.n.; D. pourtaleensis Mello-Leitão, 1944 syn.n.; D. albopunctata Mello-Leitão, 1941syn.n.) from northern Paraguay, southern Uruguay, north-central Argentina and southern Chile;D. niveovittata Mello-Leitão, 1945 from southern Paraguay, north-central Argentina andsouthern Brazil; D. anfibia (Zapfe-Mann, 1979) comb.n. (= Lycosa artigasi Casanueva, 1980)from central and southern Chile and southwestern Argentina, transferred from Pardosa C. L.Koch, 1847; D. securifera (Tullgren, 1905) comb.n. from northern Chile and northwesternArgentina, transferred from Orinocosa Chamberlin, 1916; D. arapensis (Strand, 1908) comb.n.,from Peru, transferred from Hippasella Mello-Leitão, 1944; D. calama sp.n. from northernChile; D. songotal sp.n. from southern Bolivia; D. chamberlini sp.n. from central and southernPeru; and D. oxapampa sp.n. from northern Peru. The sister-group relationship betweenDiapontia and Hippasella, and their placement in the subfamily Sosippinae, were supported byphylogenetic analyses based on four molecular markers (28S, 12S, NADH1 and COI), usingBayesian inference and maximum-likelihood. We tested whether DNA barcoding techniqueswere able to corroborate the identity of four Diapontia species. Diapontia securifera and D.anfibia were successfully identified using COI; however, D. niveovittata and D. uruguayensiswere found to share identical haplotypes and thus could not be discriminated.
