ANELOSIMUS – CLADE 30
The results corroborate the monophyly of Anelosimus s.s. (excluding Kochiura and Selkirkiella , see Agnarsson, 2004), Figures 58 and 59. Agnarsson (2004) found marginal support for Anelosimus , based on a single synapomorphy: ridges on the surface of the epigynal plate (4 -1, Figs 48A, B, 53B). With more species in the analysis this synapomorphy supports the subsidiary Eb clade within Anelosimus (see Fig. 58 and below). Here Anelosimus synapomorphies are: an entire conductor (37 -1, Fig. 8C), lack of pars stridens on prosoma

Abbreviations sp. 1–7 refer to undescribed Anelosimus spp. numbered as in the text and figures.
(90 -0, Figs 14G, 15A), three palpal tibial trichobothria (118 -1, Fig. 15G), robust femur I (119 -1, Fig. 55G) and communal (subsocial) behaviour (145 -1). The clade excluding Anelosimus sp. 1 (this undescribed species differs so much in genitalia from other species that it substantially changes the diagnosis of the Anelosimus and may, for the sake of clarity, later be placed in a new genus) is supported by: elongate (wide) epigynal plate (3 -1, Figs 19C, D, 44C, D, I, K), incised cymbial mesal margin (15 -1, see e.g. Agnarsson, 2004, fig. 22A), terminally ridged theridiid tegular apophysis (57 -1, Fig. 55D), lobed embolus tail (68 -1, Fig. 28B), abdomen pattern (98 -1, Figs 27H–M, 49E), and absence of sticky silk in web (142 -1, but see Discussion on character 142).
