 Abstract
Background: The genus Heteropoda Latreille, 1804, is ranked as the second within the family Sparassidae Bertkau, 1872. Up to now, sixteen species of this genus have been described from Malaysia.

New information: A new species of this genus in the highlands of Pahang State, Malaysia is described under the name of Heteropoda lebar sp. nov.. Individuals of the new species live in primary forests on forest floor, active in the night on the leaf litter.

Keywords: high diversity, Heteropodinae, sexual colour dimorphism, taxonomy

Heteropoda lebar sp. nov.

Diagnosis: The males of H. lebar sp. nov. can be distinguished from those of all other congeners by the widened apical part of the conductor with retrolaterad, acuminate, triangular and rounded part (Figs 1, 4a–c). Females of H. lebar sp. nov. resemble H. aemulans Bayer & Jäger, 2009 (Bayer and Jäger 2009) by the shape of median septum in ventral view, but can be recognised by the following combination of characters (Figs 2, 3, 4d–e): 1. Width of anterior part of median septum one fifth of maximal width of median to posterior part, 2. Glandular appendages elongate, small rounded in ventral view, situated at lateral margin of first winding, 3. Posterior part of internal duct system wider than long.

 Etymology: The specific name is derived from the Malay word lebar (ليبار), meaning broad and referring to the fact that the males with a widened conductor; adjective.
