Etymology.
The generic name is an arbitrary combination of letters.
Diagnosis.
The new genus seems to be closely related to
Breda
by the dentition and similar loop in the rotated bulb, which is covered by the large embolar base (
Figs 17
,
96
), but can be distinguished by having two distinct, well developed apophyses in the male palp, one ventro-retrolateral in the same position of that present in species of
Breda
(RvTA), and one curved, dorso-retrolateral (
Figs 97–98
), and by the epigynal plate of the female projecting posteriorly and with no atrium (
Fig. 99
).
Description.
Large salticids (
10–13mm
); slightly low carapace; chelicera short and vertical in both sexes, with five to seven teeth on promargin and one on retromargin; leg I longest in males, IV longest in females; tarsal claws short; abdomen slightly longer than carapace;
palp:
femur unmodified; tibia with long barbed white hairs, with two distinct, well developed apophyses, one ventro-retrolateral, short and almost straight (RvTA), and other dorsoretrolateral, short and curved prolaterally (
Figs 97–98
); cymbium oval; tegulum and subtegulum reduced (
Fig. 17
); sperm duct forming a loop in the tegulum (
Fig. 17
); embolus very elongated, broad and spiraled around the tegulum and subtegulum, with a well developed base covering the tegulum and subtegulum ventrally (
Figs 96–97
);
epigyne:
epigynal plate large, with a large posterior projection and a pair of well separated semicircular openings (
Fig. 99
); internally, the copulatory ducts begin towards the anterior part and spiral backwards to the center, leading to the small spermathecae (
Fig. 100
); fertilization ducts easily seen in dorsal view, running laterally (
Fig. 100
).
