Notes about type material. For the holotype, we chose the same specimen that Joaquin Mateu had chosen to represent this new species.

Specific epithet. The word “ deuvei ” is a Latinized genitive eponym, based on the surname of Thierry Deuve, Curator of Coleoptera , Muséum National d’Histoire Naturelle, Paris, France. Mateu recognized specimens of this species as representing a new species in 1995 and labeled them as “ Tetragonoderus deuvei n. sp. ”, but neglected to publish the description. We propose the same name to honor Dr. Deuve, as Dr. Mateu had intended.

Recognition. See the key, and figures noted above. Some specimens of T. deuvei share unicolorous elytra with the southern South American T. viridis and T. chalceus . But the latter two species have dark legs, whereas those of T. deuvei are pale. Some male features differ also, among these species, as noted above ( T. laevigatus , “Recognition”).

Description. Habitus as in Fig. 1 . See Table 1 for values for standardized body length (SBL) and ratios Hl/Hw and Pl/Pw.

Elytra. Bicolored or uniformly dark, with microsculpture mesh pattern slightly transverse, sculpticells slightly wider than long (Fig. 3B and 4B).

Male genitalia. Phallus (Fig. 5C-D) in dorsal aspect slender, shaft subsinuate, distally curved to right, narrowed toward periostial area; latter relatively long, more than one third length of shaft; apical area short, slender, apex narrowly rounded; in lateral aspect shaft relatively straight, apical area short, slender; ventral surface smooth, not ridged. Endophallus, inverted, with prominent microtrichial field, band-like in appearance in both dorsal and right lateral aspects, within medial area.

Notes about variation. Of the 23 specimens in the type series, a single specimen from Bolivia had the pale markings of the elytra much darker than typical ( Fig. 1B ), and 2 specimens from Brazil had completely dark elytra, in other words, no visible pale markings .

Notes about habitat. The Bolivian specimens of T. deuvei were collected in a cultivated grassy area near residences, and in a sand pit, among the roots of dead, standing plants.

Geographical distribution. (Fig. 6). The geographical range of this species is southern, extending from eastern Brazil westward to Paraguay and Bolivia, and northward to Amazonian Peru.

Chorological affinities. The range of this species is overlapped by that of T. quadriguttatus and mostly overlapped by that of T. laevigatus . Specimens of the latter and of T. deuvei were collected in the same place, at the same time, thus indicating that these 2 species are syntopic in at least part of their common range.

Material examined. We have seen only the type series, of 23 specimens. For details, see “ Type material”, above.
