Eupalaestrus weijenberghi (Thorel, 1894)

Distribution: Uruguay

Adult male.

Two unequal tibial apophyses of leg I in adult male.

Male palpal bulb (prolateral and retrolateral view) with four apical keels PS, PI, A, R and one subapical SA (PS, PI, A and R keel are convergent) (terminology follows Bertani, 2000).

Adult female.

Spermathecae of adult fe male.

Notes: Males of Eupalaestrus weijenberghi lack scopulae on retrolateral face of femur IV differently from the other representatives of the genus. The males of E. weijenberghi have no incrassate tibium IV in spite of the fact that this character is one of the diagnostic characters of the genus Eupalaestrus Pocock, 1901 (Pérez-Miles et al., 1996). Schmidt, 2003 states that both sexes of E. weijenberghi lack scopulae on retrolateral face of femur IV and incrassate tibia IV.
