Hadrosticta Kraatz, 1892

Hadrosticta Kraatz 1892: 378 . Type species: Hadrosticta viridiflua Kraatz 1892: 378 , by monotypy.

Description. Form elongate, subparallel, slen- der, slightly dorsoventrally flattened. Length 14–18 mm. Color of dorsum an opaque, enameled, or weakly metallic bright green or yellowish green with infusions of ochre or orange and with numerous, irregularly spaced, large black spots surrounding many punctures; venter similar but more metallic and with bluish green (depending on angle of illumination); abdominal ventrites 2–5 each with central, piceous to black, round to transverse spot. Head: Head without armature, clypeal apex bilobed, each lobe broadly rounded, not reflexed. Antenna with 10 antennomeres, club slightly longer than antennomeres 2–7. Pronotum: Subtrapezoidal, widest near base, gradually convergent to anterior angles, basomedian lobe strongly produced posteriorly, lobe covering all but tip of scutellum. Sides lacking marginal bead. Elytra: Widest at base, posthumeral emargination distinct. Bead present on lateral margins. Surface with punctures minute to small, sparse to moderate in density, most small punctures setigerous, surrounded by large, round, black spot, spots irregular in distribution, often coalescing. Pygidium: Surface similar to that of elytra, punctures denser near base, setae short (not minute). Venter: Setae long, tawny. Mesometasternal process, in lateral view, produced forward and slightly downward with acute apex recurving upwards ( Fig. 12 ). Legs: Protibia in both sexes slender, with apical tooth, and occasionally with slight swellings indicating second and third teeth. Parameres ( Figs. 14–15 ): Subtriangular in caudal view, apices broadly rounded, curving towards one another.
