Basal portion of the left elytron paired with a labeled, schematic representation of configurations of striae and basal setae. Schema after Baehr and Will 2019. s1- stria 1. s2- stria 2. s3- stria 3. pss- parascutellar stria. bs- basal setigerous puncture. abs1- angular base of stria 1. Each image represents a unique state: A. Stria 1 entire and parascutellar striole free. Platynus ovipennis (Motschultsky 1845) (Platynini); B. Stria 1 entire and parascutellar striole joined to stria 1. Amara (Curtinotus) carinata (LeConte 1847) (Zabrini); C. Angular base of stria 1 free and parascutellar striole joined to apical portion of stria 1. Stenolophus (Agonoderus) maculatus (LeConte 1869) (Harpalini); D. Angular base of stria 1 absent and parascutellar striole joined to apical portion of stria 1. Basal setigerous puncture near stria 2. Oxycrepis (Loxandrus) recta (Say); E. Angular base of stria 1 absent and parascutellar striole joined to apical portion of stria 1. Basal setigerous puncture near stria 3. Caelostomus sp. from Indonesia (Drimostomatini); F. Parascutellar stria absent, stria 1 entire. Melaenus piger (Fabricius 1801) (Melaenini).
