Pelegrina flavipes

University of Alberta E.H. Strickland Entomological Museum

SeasonalityFound most commonly in the months of May and June. Can be found as late as August (Kanston, 1996). IdentificationAll species of Pelegrina are easily distinguished from relatives by the male embolus which have two rami placed retrolaterally to the opening. This characteristic is more easily seen in P. flavipes than in any other Pelegrina species, whose ridge between these rami is the deepest. In addition, the retrolateral rami’s relative thickness is diagnostic. Males of the species sport strong and well-defined cheek bands above the side line of the head, 3 white spots above the large anterior eyes, and a small black spot on top of each of the chelicerae. Setae of two different colours overhang the chelicerae: white on the medial portion and brown on the lateral portion. Legs, chelicerae and carapace are yellow. Unlike many species of salticids, the head is not particularly bulbous or wide. Females are much more difficult to distinguish, but their best diagnostic character is their overall brassy sheen, the product of transparent scales covering the spider’s body. Beige spots can be seen above and between the anterior median eyes. The clypeus is densely covered in white scales. Also, the fourth pair of white spots on the abdomen have come together to form a chevron. On the ventral portion, the epygynum has two thickened flaps, a characteristic trait of all Pelegrina. In P. flavipes the flaps are flat and lie parallel to each other with the first curve of the duct broad while the second curve is narrow (Maddison, 1996). Males: avg. body length 3.7 mm, carapace length 1.9 mm; females: avg. body length 4.7 mm, carapace length 1.8 mm (Maddison, 1996).
