Ordo: Coleoptera
Familia: Carabidae
Name
Pediomorphus Chaudoir, 1878 – Wikispecies link – Pensoft Profile
Type species
Pediomorphus planiusculus Chaudoir, 1878: 29, by monotypy.
Selected literature
Review of genus, key to species and synonymies (Will 2010[1], 2015b[2], 2019[3]).
Described species and range
Thirteen species all restricted to Australia.
Adult morphology
Species of Pediomorphus are small, 3.5–8.2 mm (most around 4.5 mm), dorsoventrally depressed, usually pale, flavous or castaneous, usually with crenulate elytral stria. All species have enlarged labial palpomeres with a setose, ventral sensorium, subocular carina, evident elytral plica, and lack elytral discal setae.
Life history notes
Pediomorphus are commonly taken at lights at night and are known from open habitats (Moore 1965[4]), under cow dung and at the edge of swamp (Sloane 1900[5]), and I have found them under matts of dead grass along a flooded ditch (Will 2019[3]).
Discussion
The species included form a well-supported clade sister to Zeodera. In addition to DNA sequence data for the exemplars, the modified palps and derived lack of dorsal puncture on the elytra found in all species are synapomorphies.
