New North American Diplotaxis 
143 
Diplotaxis statura Cazier, new species 
Rather large, head black, pronotum cupreous black, elytra 
dark reddish-brown, shining; upper surface glabrous; lab- 
rum broadly, arcuately emarginate; mentum strongly de- 
clivous at anterior third, margins without raised line, setae 
absent at middle; hind femora with sparse irregular punc- 
tures between submarginal rows of setigerous punctures, 
hind coxae sparsely punctate in outer half ; pronotum without 
impressed line along anterior margin. 
Head with punctures above separated by about their own 
widths, sparsely punctate along clypeal suture ; clypeus with 
punctures separated by about one-half their own widths, 
margins shallowly reflexed, side and anterior margins shal- 
lowly sinuate medially, clypeal suture entire. Pronotum 
widest at middle, sides nearly straight to base and apex, an- 
terior angles not prominent ; anterior margin narrower than 
posterior ; surface shining, sparsely, finely punctate, punc- 
tures separated by about twice their own widths, interspaces 
minutely punctate. Elytra widest about middle, humeral 
and apical umbones prominent; surface shining, costae dis- 
tinct, intercostal spaces sparsely punctate, punctures sepa- 
rated by about three times their own widths. Undersurface 
sparsely clothed with short golden pile; anterior tibiae tri- 
dentate, basal tooth slightly ante-median, tarsi longer than 
tibiae, inner tooth of tarsal claws median in position, trun- 
cate. Length 12 mm., width 6 mm. 
Holotype in the writer’s collection, taken at Buena Vista, 
Sierra de la Encantada, Coahuila, Mexico, Elevation 6000 ft.,

Diplotaxis statura Cazier is most closely allied to D. den- 
tella Fall and D. completa Cazier. It can be separated from 
D. dentella by its shining, less densely punctate elytra, com- 
plete clypeal suture, and longer tarsi. From D. completa it 
can be distinguished by its less widely reflexed anterior cly- 
peal margins, less prominent anterior pronotal angles, by its 
narrower, less densely punctate elytral intercostal spaces, 
more prominent elytral costse, by the absence of the aluta- 
ceous elytral sculpturing and the median position of the 
tooth on the tarsal claws.
