Bellamy/ Repaired with; ethanol soluble; adhesive, 1993/ HOLOTYPE ; C. ballantyneae ; new species; Ferreira det. 2020 ( CMNH ). Etymology. This species is named in honor of the Australian firefly researcher Dr. Lesley Ballantyne. Dr. Ballantyne is the current world expert of the subfamily Luciolinae and has spent decades revising the Asian and Australian genera. Gender feminine. Diagnosis. This species can be separated from its congenerics by the absence of a longitudinal carina ( Fig. 1A ) (vs presence of a longitudinal carina in other species), by the disc region yellow (vs dark brown in other species) ( Fig. 1A ) and the unique shape of genitalia as illustrated in Fig. 6A . Description. General color dark brown ( Figs. 1A and 3A ), pronotal disc, prosternum, legs, and ventrites VII–VIII yellow ( Figs. 1A , 2A , 3A ). Head as long as wide ( Fig. 1A ), integument dorsally smooth, posteriorly partially covered by pronotum. Antennae absent in specimen. Pronotum not constricted medially, anterior angles round, longitudinal carina absent ( Fig. 1A ). Elytra 3× length of pronotum, moderately dehiscent, basally subparallel ( Figs. 1A and 3A ), with two weakly developed elytral costae ( Fig. 1A ). Scutellum slightly bifurcated posteriorly ( Fig.1A ). Legs:femora slightly shorter than tibiae ( Fig. 2A ). Abdomen with ventrite VII with shallow posterior notch ( Fig. 2A ), ventrite VIII elongate, longer than wide, entire, not notched apically ( Fig. 6D ). Male genitalia with median lobe stout, fusiform, apically acuminate, in ventral view bearing a strud-like structure, bifurcated APICALLY ( Fig. 6A ); parameres apically acuminate, acute ( Fig. 6A ), 1/3 shorter than median lobe; phallobase small, longer than wide, anterior margin deeply v-shaped notched, posteriorly round ( Fig. 6A ). Length (exposed portion of head+pronotum+elytra) . 2.5 mm . Width (across humerus) : 0.5 mm . Distribution. Mexico , Puebla ( Fig. 7 ). Notes. The specimen was damaged in transport and its head and pronotum were lost.
