Genus: Antilissus

Diagnostic Features
  • Description: Body cylindrical. Antennae 10-segmented with a distinct, 1-segmented club. Antennal setation sparse. Subantennal grooves present, extending behind eyes. Eyes small coarsely faceted, with scale-like interfacetal setae. Head with small, distinct temples behind eyes. Pronotal disc convex, lateral margins and pronotal disc with distinct network of pits, grooves and channels, raised areas with short, flattened, pale setae. Procoxal cavities closed. Metacoxae narrowly separated, separation less than metacoxal length. Elytra with distinct striae composed of coarse punctures. Abdominal ventrites 1-3 connate, ventrite 5 with a deep preapical groove. Tarsal formula apparently 3-3-3 (actually 4-4-4, tarsomeres 1 and 2 partially fused). Dorsal surface with short, flattened, pale setae.
  • Similar genera: The genus Antilissus is similar to the genus Lobogestoria in having an apparently 3-3-3 tarsal formula and grooved pronotum, but Lobogestoria is easily distinguished by the large, horn-like projections of the pronotum extending well over the head. Superficially, Antilissus resembles the genus Neotrichus, but the 1-segmented antennal club and distinctive network of pits, grooves and channels of the pronotum serve to distinguish Antilissus.
Known Distribution
  • Known only from Hawai'i, USA.
Biology
  • Antilissus aper have been collected off of Sideroxylon (Sapotaceae).

  • Abundance: Rarely encountered.
