Type material (2). Holotype: ARIZONA: Cochise Co.; Huachuca Mts. , 5700’; Ramsey Can. 7.viii-93; B&B Valentine, colls. ( USNM) . Paratype: ARIZONA: Cochise Co.; Huachuca Mts. , 5700’; Ramsey Can. 7.viii-93; B&B Valentine, colls. ( MTEC) .
Etymology. The species is named after Richard S. Miller (1945–2021), who first identified these specimens as a new genus and species but never described them. Rich worked primarily on Lycidae but was knowledgeable about a wide range of beetles and other insects, including all other ‘cantharoids’. Rich was a close friend and colleague of MAI and a role model and source of inspiration to VSF.
Diagnosis. Chespirito milleri can be separated from other Chespirito spp. by the combination of a dorsally unicolorous pronotum and elytra ( Fig. 1C View FIGURE 1 ) (vs. pronotal disc in C. ballantynae yellow), the pronotum not constricted medially ( Fig. 1C View FIGURE 1 ) (vs. constricted in C. zaragozai ), the last three abdominal segments distinctly yellow ( Fig. 1F, 1I View FIGURE 1 ) (vs. dark brown in C. lloydi or not distinctly yellow in C. zaragozai ) and by having ventrite 8 posteriorly entire and apically round ( Fig. 1F View FIGURE 1 ) (vs. notched in C. zaragozai ) and tergite VIII posteriorly notched ( Fig. 1I View FIGURE 1 ) (vs. tergite VIII entire in C. costae and C. hintoni ).
Description. General color dark brown ( Figs. 1C View FIGURE 1 ), mandibles, elytral insertions, trochanters, tarsi and last three abdominal segments yellow ( Figs. 1C View FIGURE 1 ). Head as long as wide; posterior 2/3 covered by pronotum ( Fig. 1C View FIGURE 1 ). Antennae when extending posteriorly reaching apical third of elytra ( Fig. 1C View FIGURE 1 ). Pronotum not constricted medially; anterior angles round; posterior margin bisinuate ( Fig. 1C View FIGURE 1 ); median longitudinal carina strongly visible throughout ( Fig. 1C View FIGURE 1 ). Elytra 3.2× length of pronotum, moderately dehiscent, basally subparallel ( Fig. 1C View FIGURE 1 ), with two weakly developed elytral costae ( Fig. 1C View FIGURE 1 ). Scutellar shield posteriorly round ( Fig. 1C View FIGURE 1 ). Abdomenal tergite VIII with distinct median notch ( Fig. 1I View FIGURE 1 ); ventrite 7 shallowly notched posteriorly ( Fig. 1F View FIGURE 1 , 2D View FIGURE 2 ); ventrite 8 elongate, fusiform, longer than wide, entire posteriorly ( Fig. 1F View FIGURE 1 ). Male genitalia with median lobe stout, fusiform, apically round, in ventral view bearing paired strut-like structure, divergent apically ( Fig. 3C View FIGURE 3 ); parameres apically acuminate, acute ( Fig. 3C View FIGURE 3 ), 1/2 shorter than median lobe; phallobase small, longer than wide, posteriorly rounded ( Fig. 3C View FIGURE 3 ).
Length (exposed portion of head+pronotum+elytra). 3.3 mm. Width (across humerus): 0.9 mm.
Distribution. Known only from the Huachuca Mountains in southeast Arizona, USA ( Fig. 4 View FIGURE 4 ).
