Type material (1). Holotype: Cuernavaca; Mor., Mex / VIII-6-1938; L. J. Lipovksy ( SEMC).

Etymology. The species is named after Professor Cleide Costa, VSF’s MSc advisor and colleague of MAI, in recognition of her many contributions to the study of immature Coleoptera , including fireflies and other bioluminescent beetles.

Diagnosis. Chespirito costae is morphologically similar to Chespirito milleri herein described, being easily separated from it by possessing the last tergite entire, apically round ( Fig. 1H View FIGURE 1 ) (vs. posteriorly notched in C. milleri ), the elytra insertion entirely black ( Fig. 1B View FIGURE 1 ) (vs. yellow in C. milleri ) and by the shape of the male genitalia ( Fig. 3B View FIGURE 3 ).

Description. General color dark brown ( Figs. 1B View FIGURE 1 ), mandibles and last three abdominal segments yellow ( Figs. 1E, 1H View FIGURE 1 ). Head as long as wide, posterior 2/3 covered by pronotum ( Fig. 1B View FIGURE 1 ). Antennae when extended posteriorly reaching apical third of elytra ( Fig. 1B View FIGURE 1 ). Pronotum not constricted medially; anterior angles round; posterior margin bisinuate ( Fig. 1B View FIGURE 1 ); median longitudinal carina strongly visible throughout ( Fig. 1B View FIGURE 1 ). Elytra ca. 3.2× length of pronotum; weakly dehiscent; basally subparallel ( Fig. 1B View FIGURE 1 ); with two weakly developed elytral costae ( Fig. 1B View FIGURE 1 ). Scutellar shield posteriorly round ( Fig. 1B View FIGURE 1 ). Abdomen with tergite VIII entire, apically round ( Fig. 1H View FIGURE 1 ); ventrite 7 with shallow notch posteriorly ( Fig. 1E View FIGURE 1 ); ventrite 8 elongate, fusiform, longer than wide, entire, not notched apically ( Fig. 1E View FIGURE 1 ). Male genitalia with median lobe stout, fusiform, apically fan-shaped, round, in ventral view bearing paired strut-like structure, divergent apically ( Fig. 3B View FIGURE 3 ); parameres bulb-shaped, apically round ( Fig. 3B View FIGURE 3 ), 1/5 shorter than median lobe; phallobase small, longer than wide, posteriorly rounded ( Fig. 3B View FIGURE 3 ).
