Fig. 16 Type material. Holotype female from Montagne d'Ambre National Park ( 12.516972°S , 49.178778°E ), 1005 m alt, Antsiranana district, Madagascar, 4.iv.2008, montane forest, col. Agnarsson and Kuntner, in NMNH. Etymology. The species epithet is a Madagascan aphorism or motto meaning 'no rush' or 'take it easy' . Diagnosis. Anelosimus moramora females can be diagnosed from all other species except Anelosimus ata by the relatively small and pointy shape of the septum and from Anelosimus ata by its smaller size. Anelosimus moramora can be diagnosed from other Madagascan Anelosimus on the basis of the following unique mtDNA nucleotide substitutions at the following standard DNA barcode alignment positions (note that only a short fragment of the divergent Anelosimus moramora barcode is available starting at position 824): C (843), C (888), T (897), A (901), C (906), A (914), C (924), C (939), C (967), A (979). It can also be diagnosed from all Anelosimus except Anelosimus torfi based on A (943). Figure 16.
