Type species : Quedius oculatus Fauvel , fixed by original designation in Blackwelder (1952) . The genus Indoquedius can be easily recognized by the following characters: Head: dorsal surface of head (and pronotum) very smooth and glossy, lacking microsculpture, two or three setiferous punctures between anterior and posterior frontal setiferous punctures along medial side of eye; labial palpomere II bearing numerous long setae on medial side forming a setal brush ( Fig. 1A ), last maxillary and labial palpomeres sparsely setose; antennomeres I–III only bearing sparse large setae, lacking dense pubescence, all antennomeres obviously longer than wide ( Fig. 1B ). Thorax: pronotum usually with two, rarely three, setiferous punctures in each dorsal row, one setiferous puncture and sometimes another less obvious and smaller puncture in each sublateral row; prothorax with additional posterior ventral plate, which divided into two pieces by median longitudinal suture ( Fig. 1C ), or entire with anterior median longitudinal ridge ( Fig. 1 D). Legs: protarsomeres I–IV strongly dilated, with ventral surface covered with dense adhesive setae. The genus Indoquedius is distributed in the Oriental and the Eastern Palaearctic regions ( Fig. 2 ). In China , six species (numbers 2, 8, 13, 19, 20 and 21) are present in the southwestern area of the country near the Himalayan region, and four (numbers 3, 5, 8 and 17) in the Island of Taiwan (of them three species are endemic). No species of this genus are known from a large territory of North-Eastern and Southern China . Only one species (number 22), described here, occurs in South-Eastern China .
