The malagasy species of the crevice weaver genus Andoharano (Araneae: Filistatidae)

Abstract

The Malagasy species of the filistatidspider genus Andoharano Lehtinen are revised. Thefour previously known species, all from caves, areredescribed and have their type material illustrated.The paratypes of A. milloti Legendre are notconspecific with its holotype and are herein describedas A. rollardae sp. nov. The first epigean representativesof the genus on the island are recorded, and afurther six species are described: A. simoni sp. nov.,A. zonsteini sp. nov., A. woodae sp. nov., A. lehtinenisp. nov., A. griswoldi sp. nov., and A. ramirezi sp.nov. Interestingly, each of the species occurring incaves is morphologically similar to a different epigeanspecies, suggesting repeated invasions of the subterraneanrealm. The fine morphology of the genus isillustrated, including the first scanning electronmicroscopy images of genitalia, spinnerets, and otherstructures.
