Erwin, Terry L., 2000, Arboreal Beetles Of Neotropical Forests: Agra Fabricius, A Taxonomic Supplement For The Platyscelis Group With New Species And Distribution Records (Coleoptera: Carabidae, Lebiini, Agrina), The Coleopterists Bulletin 54 (1), pp. 90-119 : 103

001. Agra howdenorum Erwin

( Fig. 9)

Geographical Distribution ( Fig. 9). Previously known from only Trinidad. A misidentified specimen (ADP 69350) from Obidos, Para, Brazil reported in Erwin (1982b), is, in fact, A. howdenorum .

Variation. There are two detectable differences between the specimens of Trinidad and Obidos, Brazil. The former has absolutely flat elytral intervals and a slightly lobed margin between the apical point of the elytra. The latter specimen has slightly convex intervals and a straight margin. Otherwise, I could find no difference between the two represented populations.
