Differential diagnosis

Males differ from those of all other co-generic species in the palpal bulb morphology with a conspicuous subapical curvature (ca 120°) in the embolus ( Fig. 7 ). Additionally, they differ from those of P. celiae and P. manauara by the absence of subapical triangular tooth on the embolus and from those of P. papilligera by the absence of a baso-retrolateral conical process on tibia I. Females differ from those of all other species of Paratropis in the spiral morphology of the spermathecae receptacles ( Fig. 8E ).

Etymology

The specific epithet is a noun in apposition which refers to the nickname of Sir Paul McCartney, creative motor of the legendary band The Beatles and an icon of contemporary culture.

Labio-sternal groove with two lateral mounds. Maxillae longer than wide, with the anterior prolateral lobe very elongated, conical; with 36/40 cuspules spaced, largely spread over prolatero-ventral border from the inner edge to anterior lobe. Sternum: length 4.33, width 4.97; three pairs of sigillae, anterior subcircular, median and posterior sigillae oval; anterior and median sigillae marginal, posterior submarginal. Anterior edge of sternum with a semicircular area slightly elevated (joined to labio-sternal groove). Legs: cuticle normal. Leg and palpal segments measurements provided in Table 5 .
