Holotype : Real de Arriba ; Temescaltepec; Mex. VII-33/ H. E. Hinton ; R. L. Usinger ; Collectors. / Hinton Coll.; B.M. 1939-583 ( BMNH ). Etymology. The species is named for Howard Everest Hinton (1912–1977) one of the coleopterists of the twentieth century, who was born and raised in Mexico , and collected the unique holotype . In a coincidence, he started his university education at the same institution as one of us (MAI), Modesto Junior College in Modesto, California. Diagnosis. Chespirito hintoni can be separated from other Chespirito by the combination of a unicolorous brownish pronotum and elytra ( Fig. 1A ) (vs. the yellow pronotal disc in C . ballantynae ), the pronotum not constricted medially ( Fig. 1A ) (vs. constricted in C . zaragozai ), the last three abdominal segments distinctly yellow ( Fig. 1D, 1G , 2A ) (vs. dark brown in C . lloydi or not distinctly yellow in C . zaragozai ) and by having ventrite 8 notched medially ( Fig. 1D ) (vs. entire in C . lloydi , C. milleri and C . costae ) and tergite 8 entire, round apically ( Fig. 1G ) (vs. tergite VIII notched apically in C. milleri ). Description. General color dark brown ( Figs. 1A ); mandibles and last three abdominal segments yellow ( Figs. 1D , 2A ); tarsi and metaventrite slightly lighter than remaining ventrites of the body. Head as long as wide, nearly covered by pronotum, only anterior 1/4 visible ( Fig. 1A ). Antenna short and stubby, when extending posteriorly barely surpassing humeral region ( Fig. 1A ). Pronotum not constricted medially; anterior angles round; posterior margin bisinuate ( Fig. 1A ); with median longitudinal carina strongly visible throughout ( Fig. 1A ). Elytra ca. 4× length of pronotum; moderately dehiscent; basally subparallel ( Fig. 1A ); with two weakly developed elytral costae ( Fig. 1A ). Scutellar shield round posteriorly ( Fig. 1A ). Tergite VIII entire, apically round ( Fig. 1G ). Posterior margin of abdominal ventrite 7 with a deep V-shaped notch ( Fig. 1D ); ventrite 8 elongate, fusiform, longer than wide, medially notched apically ( Fig. 1D ). Male genitalia with median lobe stout, slightly fusiform, apically rounded, in ventral view bearing paired strut-like structure ( Fig. 3A ); parameres apically rounded ( Fig. 3A ), 1/5 shorter than median lobe; phallobase missing. Length (exposed portion of head+pronotum+elytra): 3.2 mm . Width (across humerus): 0.7 mm . Distribution. Mexico state, Mexico ( Fig. 4 ).
