C230AFB9C2AE531DE0A269C3F4697743.taxon	diagnosis	Diagnosis. Males are diagnosed from other species by the shape of the theridiid tegular apophysis, bifurcated with the lower branch longer than the upper (Fig. 2 G) and the voluminous Eb (Fig. 2 E). Females differ from others of the Madagascar group, except Anelosimus ata sp. n. by the anchor-shaped septum (Fig. 2 H) and from Anelosimus ata sp. n. by the more acute curving of the copulatory duct (Fig. 2 I). Anelosimus may 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: A (31), A (223), A (274), G (517), G (529). It can also be readily diagnosed from most other Anelosimus based the following partially shared nucleotide substitutions, and all other species by their unique combination: T (58, except Anelosimus huxleyi sp. n.), G (100, except Anelosimus hookeri sp. n., and some Anelosimus darwini sp. n.), T (181, except Anelosimus ata sp. n.), G (244, except Anelosimus darwini sp. n.), T (352, except Anelosimus sallee and Anelosimus darwini sp. n.), T (355, except Anelosimus ata sp. n.), T (484, except Anelosimus torfi sp. n. and Anelosimus nazariani), T (781, except Anelosimus huxleyi sp. n. and Anelosimus salut sp. n.), G (805, except rarely Anelosimus nazariani), A (871, except Anelosimus nazariani), G (973, except Anelosimus sallee).	en	Agnarsson, Ingi, Jencik, Brian B., Veve, Giselle M., Hanitriniaina, Sahondra, Agostini, Diego, Goh, Seok Ping, Pruitt, Jonathan, Kuntner, Matjaz (2015): Systematics of the Madagascar Anelosimus spiders: remarkable local richness and endemism, and dual colonization from the Americas.

C87AB8F1821009FD8A5FA11CB688E15A.taxon	diagnosis	Diagnosis. Anelosimus salut females can be diagnosed by having a broad ' inverted T-shape' septum that differs from Anelosimus vondrona in not extending the entire length of the epigynum (Fig. 5 J). Males can be diagnosed from all other Anelosimus by the relatively short bifurcated TTA (Fig. 4 C) and the bilobed embolic division b that is longer and narrower than in other species (Fig. 4 D).

E5EC094D99C3631A8A9F11BB12E0FE02.taxon	diagnosis	Diagnosis. Anelosimus nazariani differs from other species in being distinctly the largest Anelosimus species recorded to date with female total length exceeding 7 mm, with other species ranging from 1.9 - 5.5 mm. The males are easily diagnosed by the dark, bulky, and comparatively smooth Eb (Fig. 5 E-F), and all but Anelosimus sallee by the very elongated upper branch of the TTA (Fig. 5 D-E). The TTA differs in shape from that of Anelosimus sallee, being less curved. The epigynum differs from all but Anelosimus andasibe, Anelosimus buffoni sp. n., and Anelosimus wallacei sp. n. by the W pattern on the septum, and from these three by the larger distance between the septum and the epigynal margin (Fig. 5 A). Anelosimus nazariani 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: T (24), T (45), T (100), T (202), G (322), T (424), G (583), T (814), T (859).

A4CFFA57F8905C92270DBE9D9CDA60C4.taxon	diagnosis	Diagnosis. Males are readily diagnosed from all species other than Anelosimus nazariani by the elongate upper branch of the TTA (Fig. 6 B) and from Anelosimus nazariani by the greater curvature of this branch.

16865FC07744AC9D5759D3903A3DC364.taxon	diagnosis	Diagnosis. Anelosimus andasibe differs from all but Anelosimus nazariani, Anelosimus buffoni sp. n., and Anelosimus wallacei sp. n. by the W-shaped septum (Fig. 6 E), and from Anelosimus nazariani by the small distance between the septum and the epigynal margin and by being smaller. Clear diagnostic features separating females of the very similar Anelosimus andasibe, Anelosimus buffoni sp. n., and Anelosimus wallacei sp. n. have not been established, however, we predict they will be readily diagnosable based on palpal organs once males are discovered. Anelosimus andasibe can be diagnosed from Anelosimus wallacei sp. n. by lacking substitution A (241), and from Anelosimus wallacei sp. n. and Anelosimus buffoni sp. n. by lacking substitution G (249). It 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: C (124), G (415), G (496), G (769). It can also be readily diagnosed from most other Anelosimus based the following partially shared nucleotide substitutions, and all other species by their unique combination: G (79, except some Anelosimus lamarcki sp. n.), G (184, except Anelosimus buffoni sp. n. and Anelosimus wallacei sp. n.), G (202, except most Anelosimus ata sp. n.), T (479, except Anelosimus nazariani), G (511, except Anelosimus buffoni sp. n. and Anelosimus wallacei sp. n.), T (553, except Anelosimus tita), T (709, except Anelosimus ata), G (772, except Anelosimus lamarcki), (796, except Anelosimus buffoni and some Anelosimus may), G (838, except Anelosimus darwini).	en	Agnarsson, Ingi, Jencik, Brian B., Veve, Giselle M., Hanitriniaina, Sahondra, Agostini, Diego, Goh, Seok Ping, Pruitt, Jonathan, Kuntner, Matjaz (2015): Systematics of the Madagascar Anelosimus spiders: remarkable local richness and endemism, and dual colonization from the Americas.

A5DAA06EA7A104F984BB3F5DE0066574.taxon	diagnosis	Diagnosis. Anelosimus huxleyi females can be diagnosed from all other species except Anelosimus vondrona, by the relatively broad septum that extends the entire width of the epigynum (Fig. 14 D-E) and from Anelosimus vondrona by the more heavily sclerotized lower margin of the epigynal plate (Fig. 14 D-F). Anelosimus huxleyi 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: A (283), A (418), T (760), G (784). It can also be readily diagnosed from most other Anelosimus based the following partially shared nucleotide substitutions, and all other species by their unique combination: T (22, except Anelosimus tita and Anelosimus hookeri), T (58, except Anelosimus may), A (133, except Anelosimus darwini), G (181), T (139, except Anelosimus sallee), G (619, except Anelosimus vondrona), G (625, except Anelosimus torfi and Anelosimus ata), T (781, except Anelosimus may and Anelosimus salut), G (817, except Anelosimus torfi), T (838, except Anelosimus sallee).	en	Agnarsson, Ingi, Jencik, Brian B., Veve, Giselle M., Hanitriniaina, Sahondra, Agostini, Diego, Goh, Seok Ping, Pruitt, Jonathan, Kuntner, Matjaz (2015): Systematics of the Madagascar Anelosimus spiders: remarkable local richness and endemism, and dual colonization from the Americas.

Anelosimus buffoni females can be diagnosed from all other species expect Anelosimus andasibe and Anelosimus wallacei by the W pattern of the septum (Fig. 15 B-C) and from Anelosimus wallacei by lacking substitution A (241), from Anelosimus andasibe by having substitution G (349), and by both by having substitution A (559). Anelosimus buffoni 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: G (742), T (769). It can also be readily diagnosed from most other Anelosimus based the following partially shared nucleotide substitutions, and all other species by their unique combination: G (364, except some Anelosimus salut), G (184, except Anelosimus wallacei and Anelosimus andasibe), G (511, except Anelosimus andasibe and Anelosimus wallacei), G (796, except Anelosimus andasibe and some Anelosimus may), G (799, except Anelosimus vondrona).	en	Agnarsson, Ingi, Jencik, Brian B., Veve, Giselle M., Hanitriniaina, Sahondra, Agostini, Diego, Goh, Seok Ping, Pruitt, Jonathan, Kuntner, Matjaz (2015): Systematics of the Madagascar Anelosimus spiders: remarkable local richness and endemism, and dual colonization from the Americas.
