- Abstract
Summary: A new species of the genus Talanema , T. maculatum sp. n., collected in a natural enclave of Iran, is characterised on the basis of morphological and molecular data. It is distinguishable by its 1.82-2.20 mm long body, lip region offset by constriction and 20-23 μ m wide with perioral liplets, odontostyle 21.5-28 μ m long, guiding ring double, neck 394-525 μ m long, pharyngeal expansion occupying 44-49% of the total neck length, uterus tripartite and 308-441 μ m long or 5.1-6.8 body diam., vulva transverse (V = 54-58), presence of abundant cuticle irregularities at the perivulval area, tail similar in both sexes, conical with a dorsal concavity (31-45 μ m, c = 46-71, c′ = 0.9-1.1), spicules 70-75 μ m long, and 14-18 shortly spaced ventromedian supplements ending at level of the anterior end of spicules, with hiatus. Molecular analysis of 28S-rDNA gene confirms the monophyly of Talanema and the difficulties in elucidating its external evolutionary relationships.
