Characteristics of Isepeolini and its constituent genera. aMelectoides desiccata Packer & Graham n. sp., allotype female apex of metasomal venter to show apical process of S6 (red line) with apicolateral rows of robust setae and overlapping membranous flap (blue line). Scale bar 0.5 mm (millimetre). bM. desiccata allotype female apex of metasomal dorsum to show membranous extension to posterior margin of T5 (red line). Scale bar 0.5 mm. cIsepeolus luctuosus apex of metasomal venter to show pointed apex to S6 (red line) and absence of both robust setae and large membranous flap. Scale bar 0.5 mm. dI. luctuosus to show absence of membranous extension to posterior margin of T5 (red line). Scale bar 0.5 mm. eI. mankalunthata Packer and Graham n. sp. holotype male face frontal view to show concavity of vertexal area between lateral ocellus and compound eye (red line). Scale bar 1 mm. fM. niveiventris male face frontal view to show lack of distinct concavity between lateral ocellus and compound eye. Scale bar 1 mm
