Abstract

Dinopelma Bates, 1889 species from Mindanao Island, Philippines, are reviewed. Examination of material representing the two species previously described from Mindanao showed that they represent immature and mature forms of the same species. Therefore, the following synonymy is established: Dinopelma lineola Andrewes, 1932 = D. marginatum Andrewes, 1932 syn. nov. Dinopelma pandanicola sp. nov. is described from two localities on Mindanao Island. Owing to the absence of basolateral pronotal setae, the new species resembles D. angustum Andrewes, 1931 from Borneo, but it differs in its larger body size, more broadly rounded lateral margins of the pronotum, and male genitalia. A lectotype is designated for D. marginatum Andrewes, 1932. The two species currently known from Mindanao are diagnosed, and their habitus and male genitalia are illustrated. We also briefly discuss characters distinguishing the genera Dinopelma and Hexagonia Kirby, 1825. Leaf axils of various Pandanaceae are recorded as a preferred habitat of hexagoniine ground beetles in Mindanao.
