Etymology. This species is named in honor of Dr. Santiago Zaragoza Caballero. Professor Zaragoza is one of the greatest Mexican entomologists who dedicated his life to the study of Elateroidea ‘cantharoid’ beetles in his prolific career at the Instituto de Biología, Universidad Nacional Autónoma de México ( UNAM ). Professor Zaragoza was responsible for inspiring and mentoring generations of students in Mexico and is a role model and an example of dedication in the world of coleopterology in Latin America. Gender masculine. Diagnosis. This species can be separated from its congenerics by the pronotum strongly constricted medially (vs weakly or not constricted pronotum) ( Fig. 1C ), by the ventrite VIII elongate, longer than wide, bifurcated posteriorly ( Fig. 6F ) (vs entire in other species), the strongly dehiscent elytra (vs weakly or moderately dehiscent in other species) and by the unique shape of genitalia as illustrated in Fig. 6C . Description. General color dark brown ( Fig. 1C ), coxae, trochanter, and last ventrite light yellow ( Figs. 1C and 3C ). Head longer than wide ( Fig. 5A ), integument dorsally alveolate ( Fig. 5A ), posteriorly partially covered by pronotum. Pronotum strongly constricted medially, anterior angles slightly bisinuate, longitudinal carina present, with disc area in posterior 2/3 smooth, posterior margin bisinuate ( Fig. 1C ). Mesosternum medially elevated, carinated. Elytra 2.5× the length of pronotum, strongly dehiscent ( Figs. 1C and 3C ) with two weakly developed elytral costae ( Fig. 1C ). Scutellum entire ( Figs. 1C and 5C ). Legs: trochanters tubular, moderately elongate; meso- and metafemora subequal in length ( Figs. 1C and 5D ). Abdomen with ventrite VII as long as wide and extremely reduced, posteriorly entire, without notch; ventrite VIII elongate, longer than wide, bifurcated posteriorly ( Fig. 6F ). Male genitalia with median lobe stout, fusiform, apically acuminate ( Fig. 6C ); in ventral view bearing a plate-like structure, bifurcated apically ( Fig. 6C ); parameres apically blunt ( Fig. 6C ), 1/6 shorter than median lobe; phallobase large, transverse, anterior margin shallow, round, posteriorly round ( Fig. 6C ). Length (exposed portion of head+pronotum+elytra). 2.6 mm . Width (across humeri). 0.6 mm . Distribution. Mexico , Chiapas ( Fig. 7 ).
