Figure 20. Anelosimus cf. jucundus, male palp. A, mesial; note deep cymbial incision, an Anelosimus synapomorphy (25-1). B, ventral; note ectal outgrowth of the tegulum (arrow, closer view in D, 46-1). The embolus spiral is split along nearly its entire length, forming a thin sclerotized part containing the duct (the E) and the large embolic division b (Eb, 99-1). C, distal tip, ventral. D, details of basal portion of E, the tegular outgrowth unique to A. cf. jucundus. E, apical part. F, details of ridge on E, Eb; note forked E tip (arrow, 88-1). Scale bars: A-D, 100 Mm; E, F, 50 Mm.
