ETHICUS GROUP – CLADE 21

To my knowledge an araneid-like epigynal scape (1 -1, Fig. 55A View Figure 55 ) is present in only eight theridiid species, and these are all closely related, together forming the epigynal scape clade ( Fig. 59 View Figure 59 , clade 23). In addition to the scape the monophyly of this clade is also supported by the sperm duct trajectory switchback I touching (29 - 1), and modification of the stridulatory system, with a straight row of tightly spaced, numerous, stridulatory picks on the abdomen (102 -2, 106 -0, see Agnarsson, 2004: fig. 26D,E). This lineage contains the ethicus group, the third American clade, containing A. ethicus , A. nigriscens (previously subsumed within A. ethicus ), A. rabus Levi, 1963 , and four new species (revised by Agnarsson, 2005). The ethicus group is united by: copulatory ducts encircling spermathecae (8 -1), a bulky theridiid tegular apophysis (51 -0, Fig. 57C View Figure 57 ), with a distal hook (52 -2, Fig. 57B View Figure 57 ) and a simple short Eb (78 -1, Fig. 57C View Figure 57 ).
