Key to species of Sesaspis Casey

1 Elytral sculpture reduced, at most a faint straight elevation of the 3 rd or 5 th elytral interval, and weak elevation at start of declivity; apex of elytra almost smooth, if weakly emarginate not swollen along suture....................................... 2

- Elytral sculpture well developed with any combination of distinct parallel or arcuate ridges and large nodules; apex of elytra weakly to strongly emarginate, if weakly emarginate then swollen along suture ......................................... 3

2 Elytra with faint elevation in 5 th interval; lateral margin of apical declivity smooth. Mexico, Nuevo Leon. Fig. 19 View FIGURES 16–19 ... ......................................................................................................................................... S. doyeni (García-París et al.)

- Elytra with faint elevation in 3 rd interval; lateral margin of apical declivity weakly serrate. Mexico, Hidalgo. Fig. 18 View FIGURES 16–19 ................................................................................................................................................. S. ashei NEW SPECIES

3 Elytra with two distinct almost straight parallel ridges from base to declivity, ridge in 3 rd terminating in small nodule before apical margin; apex of elytra strongly emarginate; antennomere 3 short and transverse subequal in size to 4; male nodules absent on all femora. Texas, New Mexico. Tamalipas. Fig. 27 View FIGURES 26–29 ............................. S. emarginata (Horn)

- Ridge in 3 rd elytral interval weak, indistinct, or series of disconnected nodules for most of length, ridge in 5 th if present strongly arcuate; apex of elytra weakly emarginate; antennomere 3 slightly to obviously elongate, longer than 4; male nodules present on at least pro and mesofemora..................................................................................... 4

4 Elytral ridge in 3 rd interval reduced medially, distinct apically, extending almost to apical margin; apex of elytra only slightly emarginate; nodule at start of apical declivity weak, connected to ridge; vestiture of dense bristle-like setae. Mexico. Fig. 17 View FIGURES 16–19 ........................................................................................................................... S. denticulata (Solier)

- Elytral ridge in 3 rd interval reduced to almost absent, or consisting of series of rounded nodules; 3 rd interval terminating in large round or arcuate nodule at start of apical declivity; vestiture tomentose ................................................. 5

5 Ridge in 3 rd elytral interval formed by disconnected round nodules; elytral suture at apex not swollen; nodules at start of declivity strongly rounded or conical; subgenal ridge strongly thickened with enclosed median depression or pit. Mexico, Chiapas and Central America. Fig. 26 View FIGURES 26–29 ....................................................... S. triplehorni NEW SPECIES

- Ridge in 3 rd elytral interval indistinct, elytra flattened dorsally; elytral suture strongly to weakly swollen; nodules at start of declivity arcuate; subgenal ridge well developed but with distinct posterior bend ......................................... 6

6 Apical margin of elytra bifid with two distinct nodules, suture weakly swollen; posterior angles of pronotum obtuse and rounded; dorsal surface of head with apical margin of frons flat, margin of suprantennal ridge slightly emarginate, channels at base of suprantennal ridge straight. Mexico, Oaxaca. Fig. 28 View FIGURES 26–29 ............................................................. ...................................................................................................................................................... S. lutosa (Champion)

- Apex of elytra with single nodule, suture strongly swollen with short ridge; posterior angles of pronotum expanded, sharpened to approximately 90° angle; dorsal surface of head with apical margin of frons concave, margin of suprantennal ridge rounded, channels at base of suprantennal ridge arcuate. Mexico. Fig. 29 View FIGURES 26–29 .. S. sylvatica (García-París et al.)
