Anelosimus salut Agnarsson & Kuntner, 2005 Fig. 4

Notes.

New material of males of this species allowed a more detailed study of the palpal organ and we provide new illustrations and diagnosis of the male; the original description included a single drawing (see Agnarsson and Kuntner 2005, fig. 5D).

Type material.

Holotype male and paratype female, Périnet Special Reserve (P.N. Andasibe Mantadia), Toamasina Province, Madagascar, (18.935°S, 48.418°E), 24.xii.2001, montane forest, 1000 m, col. M. E. Irwin, E. I. Schlinger, H.H. Rasolondalao, in CAS, examined.

Other material.

Additional specimens from same locality, 3-20.iv.2008 and 12-28.xi.2008, col. Agnarsson, Kuntner, and Hanitriniaina.

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. 5J). Males can be diagnosed from all other Anelosimus by the relatively short bifurcated TTA (Fig. 4C) and the bilobed embolic division b that is longer and narrower than in other species (Fig. 4D). Anelosimus salut 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 (38), T(43), T(97), T (369), A (371), T (415), G (460), A (470), A (494), A (568), T (796). 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: A (256, except Anelosimus torfi sp. n. and Anelosimus hookeri sp. n.), T (370, except Anelosimus torfi sp. n.), T (412, except Anelosimus torfi sp. n.), A (469, except Anelosimus torfi sp. n.). A (474, except Anelosimus nazariani ), G (521, except Anelosimus vondrona ), G (541, except Anelosimus sallee and some Anelosimus wallacei sp. n.), A (622, except Anelosimus torfi sp. n.), T (631, except Anelosimus darwini sp. n.), A (754, except Anelosimus torfi sp. n.), T (781, except Anelosimus may and Anelosimus huxleyi sp. n.), T (940, except Anelosimus torfi sp. n.), A (961, except Anelosimus torfi sp. n.), G (994, except most Anelosimus huxleyi sp. n.).

Distribution.

Only known from type locality.

Natural history.

As other species in this group Anelosimus salut appears to be subsocial with colonies consisting of single females and up to 39 spiderlings.
