1	Elytra with all kinds of punctures relatively large, about the same size and degree of impression, all seemingly longitudinally aligned and uniformly distributed (Fig. 6A, D)	2
–	Elytra with serial punctures either larger, denser or more impressed (or a combination of those features) than the remainder punctures; interserial punctures either similar in size, smaller, denser, longitudinally aligned or irregularly distributed regarding serial punctures (e.g. Figs 7A, D, G, 8A, D, 9A, D, 10A, D)	3
2	Eyes relatively small (ventral face of the eye only slightly wider than antennal club), separated by distance 6 × larger than largest diameter of eye in dorsal view (Fig. 2I)	Tobochares microps
–	Eyes of normal size (ventral face of the eye nearly twice as wide as antennal club), separated by distance 4.5 × larger than largest diameter of eye in dorsal view (Fig. 2H)	Tobochares communis
3	General coloration orange brown with black head (Fig. 7G, H); all elytral punctures similar in size and degree of impression, most equidistant from each other; serial punctures only seemingly longitudinally aligned (Figs 3F, 7G); aedeagus with apex of median lobe emarginate (Fig. 11E)	Tobochares pemon
–	General coloration dark brown; elytral punctation variable; aedeagus with apex of median lobe variable, but never emarginate	4
4	Surface of elytra sharply impressed along rows of serial punctures, forming well-defined striae along posterior 2/3 of elytra (Fig. 8A, D)	5
–	Surface of elytra not or only slightly and uniformly impressed, forming shallow grooves along entire rows of serial punctures (e.g., Fig. 7A)	6
5	Body size around 2.6 mm; elytral striae rather shallow (Fig. 8A, B); mesofemur with a well-defined patch of dense hydrofuge pubescence along anterobasal corner (Fig. 8C); metafemur 2.5 × longer than wide (Fig. 8C)	Tobochares romanoae
–	Body size around 2.0 mm; elytral striae rather broad and deep (Fig. 8D, E); mesofemur with a reduced patch of scanty hydrofuge pubescence on anterobasal corner (Fig. 8F); metafemur nearly 2 × longer than wide (Fig. 8F)	Tobochares akoerio
6	Serial punctures longitudinally aligned and slightly impressed forming shallow grooves (Fig. 7A); interserial punctures somewhat irregularly distributed in a single row (Fig. 7A)	Tobochares anthonyae
–	Serial punctures never impressed to form grooves; interserial punctures variable in distribution	7
7	Serial punctures longitudinally aligned, larger than interserial punctures (Fig. 3B, G); interserial punctures longitudinally aligned, more densely arranged than serial punctures (Fig. 3B, G); median lobe gradually narrowing towards apex from near base (Fig. 11G)	Tobochares atures
–	Serial punctures seemingly longitudinally aligned, more densely arranged than interserial punctures (e.g., Fig. 3C); interserial punctures randomly distributed (e.g., Fig. 3H, I); median lobe broad, only narrowing along apical third (e.g., Fig. 11L–N)	8
8	Elytra with 1 or 2 irregular rows of interserial punctures (elytral punctation moderately dense, Figs 3H, 9A, D); tibiae orange to orange brown in coloration; maxillary palps bright yellow	9
–	Elytra with 2 or 3 irregular rows of interserial punctures (elytral punctation highly dense, Figs 3I, 10A, D); tibiae reddish brown in coloration; maxillary palps tan yellow	10
9	Lateral coloration of pronotum and elytra gradually paler, orange (Fig. 9B); legs orange (Fig. 9C); serial punctures along outer surface of elytra equally impressed as those on dorsal surface (Fig. 9B)	Tobochares kappel
–	Coloration of pronotum only slightly paler along antero-lateral margin (Fig. 9E); legs reddish brown (Fig. 9F); punctures on outer surface of elytra more strongly impressed along apical region than those on dorsal surface (Fig. 9F)	Tobochares kolokoe
10	Elytral punctation sharp and dense (Fig. 10D); apodemes of the median lobe one fourth the length of the median lobe (Fig. 11N)	Tobochares canaima
–	Elytral punctation shallow and relatively sparse (Fig. 10A); apodemes of the median lobe nearly half as long as the median lobe (Fig. 11M)	Tobochares arawak
