JABBASTYGNUS GEN. NOV.

Etymology: Genus name is derived from Jabba the Hutt, a character from Star Wars, complemented by the preexisting genus Stygnus Perty, 1833 . This refers to the shape of male genitalia which resembles the grotesque face of this character. Gender masculine.

Type species: Jabbastygnus huttorum sp. nov.

Diagnosis: The new genus is here primarily compared with three other genera of Stygninae (see Discussion for details). Dorsal scutum outline alpha, but with posterior margin widened (like Ricstygnus , unlike Auranus , rectangular or Stygnus , pyriform or convex without constrictions); interocular mound high, with two short spines in longitudinal row (unlike Ricstygnus , high, with one high spine; Stygnus , only the spine without mound; Auranus , without interocular mound, but with the whole carapace strongly convex); mesotergum divided into 4 areas (as in Ricstygnus , unlike Auranus / Stygnus with 3 areas); scutal area III unarmed (as in Ricstygnus , unlike Auranus / Stygnus , with a pair of high acuminate spines); basitarsomeres IV thickened (unlike Auranus , Ricstygnus , Stygnus ); VP separated from truncus by a deeply multi-wrinkled toroidal region (as in Auranus hehu ; unlike Ricstygnus / Stygnus ); complex truncus-glans co-linear (as in all other Stygninae, except Auranus , where VP arises after an abrupt change in the direction of truncus); lamina parva strongly thickened dorso-ventrally (as in Auranus , Ricstygnus , Stygnus ); lamina parva with a flat, rounded, subquadrangular platform + a pair of erect middorsal lobes (as in Auranus hehu and A. parvus , unlike any other Stygninae); MS A1–A3 forming slanted row widely separated from B, which is ventrally inserted (as in Auranus ; unlike Ricstygnus / Stygnus , with A1– A2 transverse, contiguous with B); MS C1–C3, slender, in transverse sub-distal row (as in Auranus ; unlike most other Stygninae shaped like immense buffalo-horns in longitudinal row); MS E1–E2 elongate, closely set (unlike Ricstygnus / Stygnus , with minuscule E1–E2 inserted close to each other; unlike Auranus , with E1 widely separated from E2, both elongate).
