The Eulichas mediocris species complex

The complex comprises two species from Sumatra and surrounding small islands, which should be characterised by the pronotum with sides subbasally parallel, or slightly incised with hind angles prominent. Last antennomere almost rectangular, not distinctly widened. Parameres with subbasal hook developed, but the subapical hook is absent. Body length relatively small (males: 14–19 mm, females: 19–26 mm).
