Key to species of Gonaphodiopsis

1. Pronotal dual punctation dense and almost uniformly scattered throughout ( Fig. 105 , 115 ) .. 2

— Pronotal dual punctation sparse and rather irregularly scattered ( Fig. 111 , 122, 126 ) ............ 3

2(1). Elytra elongate, feebly widened posteriorly ( Fig. 106 ); interstriae feebly convex on disc, somewhat more convex on preapical declivity. Reddish brown, pronotum and elytra shadowy darker on disc. Length 4.0-4.5 mm. Mexico (Oaxaca, Puebla, San Luis Potosí, Tamaulipas, Veracruz) ............................................................................................................. G. deloyai new species

Mexico (Veracruz) ... .................................................................................................. G. montesdeocai new species

3(1). Basal margin of pronotum with a belt of coarse contiguous punctures crenulating a sort of thick edge ( Fig. 111 ); lateral margins of pronotum slightly inwardly sinuate before hind angles; truncation of hind angle inwardly sinuate; elytral interstriae slightly convex on disc, subcariniform on preapical declivity. Chestnut brown more or less dark. Length 5.0-5.5 mm. Mexico (San Luis Potosí, Tamaulipas, Veracruz) ............................ G. hypogea new species

— Basal margin of pronotum without such a belt of punctures ...................................................... 4

4(3). Large pronotal punctures moderately coarse, very sparse on sides and widely lacking medially; small punctures almost imperceptible on disc ( Fig. 122 ); elytral striae fine, superficially punctured, faintly crenulate; interstriae almost flat on disc, very feebly convex on preapical declivity, almost impunctate. Piceous or blackish. Length 5.0-5.5 mm. Mexico (Chiapas) .... .......................................................................................................... G. pachecoi new species

— Large pronotal punctures strongly coarse and rather dense on sides; small punctures distinct also on disc, even if therein more superficial ( Fig. 126 ); elytral striae rather deep, coarsely punctured, crenulate; interstriae convex on disc, subcariniform on preapical declivity, sparsely finely punctured. Reddish brown, pronotum disc and elytra somewhat shadowy darker. Length 4.5-5.0 mm. Guatemala, Mexico (Chiapas) ............................. G. teopiscaensis new species
