Genus Dusmadiores Jocqué, 1987

Updated diagnosis. Representatives of Dusmadiores are small Zodariidae (1.5–3.2) recognized by the femoral organ with grooved, sometimes also barbed, setae on all legs ( Fig. 7 C) and the modified uniseriate setae along the prolateral side of the last palpal segment, both in males and females ( Fig. 6 A). Abdomen without a row of setae in front of the tracheal spiracle. The male palp is characterized by its complexity with a large median apophysis and conductor and long, flattened embolus ( Fig. 6 A). Females have widely separated spermathecae and atria of variable size between the spermathecae ( Fig. 6 C).

Remark. The structure of the male palp of zodariids is very variable and complicates the statement about homology of the sclerites. Some researchers have solved the problem by defining different sclerites according their position. Jocqué & Baehr (1992) recognized a distal tegular apophysis and a ventral tegular apophysis. For the very complex palps in the genera around Asteron, Baehr & Jocqué (2001) added the lateral tegular apophysis and the prolateral tegular apophysis. This procedure avoids the necessity to imply a homology for the different sclerites. In Dusmadiores , the male palp is characterized by the large, broad and rigid embolus and the presence of one large complex sclerite that is most often positioned in the centre of the tegulum, sometimes accompanied by a less complex structure in the centre of the tegulum. The former is sometimes wrapped around the embolus and could then be considered a conductor as is the case in D. elgonensis . In other species, as in D. deserticola , it is positioned in the centre of the tegulum and independent from the embolus. In that case it can be seen as a median apophysis. We have therefore named the large complex sclerites with regard to their position and function.
