Anelosimus tita Agnarsson, Kuntner & Jencik View in CoL sp. n. Fig. 10

Type material.

Holotype female from Ambohitantely Special Reserve (18.161°S, 47.302°E), 1500 m alt, Analamanga region, Ankazobe district, Madagascar, 28.iv.2008, montane forest, col. Agnarsson and Kuntner, in NMNH.

Other material.

Only known from holotype.

Etymology.

The species is a noun in apposition named in the honor of the first author’s mother-in-law Yadira Collado Ulloa, affectionately known to her grandchildren as ‘Tita’.

Diagnosis.

Anelosimus tita can be diagnosed from other Madagascan Anelosimus by the triangular shape of the septum (Fig. 10E) and on the basis of the following unique mtDNA nucleotide substitutions at the following standard DNA barcode alignment positions: T (30), G (37), T (80), T (81), T(82), A(83), G (109), G (214), T(220), G (319), T (328), T (586), T (625), G (873), G (883), A (903), G (919). 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 hookeri and Anelosimus huxleyi ), T (121, except Anelosimus nazariani ), G (190, except some Anelosimus huxleyi ), G (262, except Anelosimus nazariani ), T (532, except some Anelosimus huxleyi ), T (553, except Anelosimus andasibe ).
