Peltochares is a genus of water scavenger beetles in the family Hydrophilidae represented by eight described species. [1] It is distributed across the Afrotropical, Australasian, Indo-Malayan, and Palaearctic realms. [1]

Taxonomy

The genus Peltochares was described for the first time by Maurice Auguste Régimbart in 1907 [2] for a single, large, and morphologically unusual species from Gabon (Peltochares conspicuus). [3]

Thanks to the result of a molecular-based phylogenetic analysis,[4] along with dissections of the male genitalia, several species formerly placed in the genus Helochares were confirmed to belong in the same genus as that large and morphologically unusual species. [1]

Description

Medium-sized to relatively large beetles (6–14 mm), weakly to moderately convex in lateral view, dark brown in coloration. A diagnosis of the genus as currently circumscribed was presented by Girón and Short.[1]

Species

  1. Peltochares atropiceus (Régimbart, 1903) [5]
  2. Peltochares ciniensis (Hebauer, Hendrich, and Balke, 1999) [6]

  4. Peltochares discus (Hebauer, Hendrich, and Balke, 1999) [6]
  5. Peltochares foveicollis (Montrouzier, 1860) [7]
  6. Peltochares longipalpis (Murray, 1859) [8]
  7. Peltochares papuensis (Hebauer, 1995) [9]
  8. Peltochares taprobanicus (Sharp, 1890) [10]
