Chenopod Bug Coridromius chenopoderis Tatarnic & Cassis, 2008

(after Tatarnic & Cassis 2008): Coridromius chenopoderis is recognized by the following combination of characters: proepisternum unilobed; metanotum not prominently flared; posterior margin of pygophore biconvex, with prominent fold on left side forming deep U-shaped groove, without small apophysis on right margin of groove. Coridromium chenopoderis, C. monotocopsis, C. pilbarensis, and C. variegatus are all very similar and often difficult to tell apart. Of the four species, C. chenopoderis exhibits the most phenotypic variation in both size and coloration and has the widest variety of known host plants of all Coridromius. It has a somewhat narrower body shape and is typically smaller than the others, though size ranges do overlap. Males can be distinguished from the other species by the relatively shorter left paramere, the much deeper U-shaped fold on the posterior margin of the pygophore, by the lack of a small apical process on the right margin of this fold (found only in pilbarensis) and by the lack of a small rounded lobe on the posterior margin of the metepimeron as found in variegatus.
