Diagnosis

The species has a fissident chelicera, which is characteristic for the genus. The female differs from Longarenus brachycephalus Simon, 1903 in having an epigyne with the anterior heart-shaped depression. The course of the seminal ducts is also different (compare Fig. 40D with Wesołowska & Edwards 2012: fig. 59).

Etymology

The specific epithet is a noun in apposition and refers to the type locality.
