THE DOMINGO View in CoL GROUP – CLADE 13

Three species, A. jabaquara , A. domingo and A. dubiosus ( Keyserling, 1891) , belong to this welldefined group. The females are nearly indistinguishable from other Anelosimus externally, but internal female genitalia, and male genitalia, offer easy diagnosis. The clade is supported by four unreversed palpal synapomorphies: finger-like apophysis on the theridiid tegular apophysis (54 -1, Fig. 7A, K View Figure 7 ), whiplike embolus spiral (60 -1, Figs 7A, B, E, F, K, L View Figure 7 , 9B, C, E View Figure 9 ), cup-shaped Eb apophysis (81 -1, Figs 7B, E, L View Figure 7 , 9E View Figure 9 , 11D View Figure 11 , 13E View Figure 13 ), and embolus supported by Eb apophysis (79 -2, Fig. 7B, E, F, L View Figure 7 ). Having sticky silk in the web (142 -0) may be an additional synapomorphy, but absence of sticky silk in most Anelosimus webs remains doubtful (see below). All three species are social and adult females at least sometimes share webs. Anelosimus domingo is a typical social species with permanent colonies and strongly biased sex ratio.
