( Figs. 3–4 View FIGURES 3 – 6 , 12 View FIGURES 10 ­ 13 , 14–16 View FIGURES 14 ­ 20 , 21–23, 29 View FIGURES 21 ­ 32 , 33 View FIGURES 33 ­ 34 )

Holotype: Male. Length 4.1 mm. Head, pronotum, elytra and underside dark brown with faint metallic sheen; antenna reddish brown, segments 7–9 paler. Legs dark reddish brown. Mouthparts reddish brown, mandibles piceous; with apex of labrum emarginate, with 2 dorsal setae and short row of lateral setae along outer margin. Mandibles with lateral surface smooth and setose. Prothorax distinctly wider than long, L/W = 0.59; pronotum strongly convex, anterior angles acute, directed antero­laterally; lateral margins narrow, rounded, strongly converging in apical third, with widest part of pronotum anterior to middle; disc regularly, finely punctate, with punctures separated by a distance greater than their diameters. Prosternum with long setae, finely punctate, expanded laterally behind coxae; intercoxal process shallowly concave, its posterior margin weakly emarginate, lateral angles of intercoxal process thickened, width of intercoxal process 0.56 x diameter of procoxa. Mesosternum flat between coxae, surface smooth, with long yellow setae. Metasternum narrow between meso­ and metacoxae, weakly alutaceous, with short yellow setae. Elytra inflated, punctate­striate in apical half, more or less evenly punctate in basal half, with punctures in striae separated by distance much less than the diameter of a puncture; surface between punctures smooth with scattered small punctulae; humeri not prominent, broadly rounded, width across humeri 1.1 x width across pronotum; basal calli obsolete; postbasal depression lacking; sides broadly rounded, convergent; apices conjointly rounded. Hind wing reduced to a narrow strap ( Fig. 12 View FIGURES 10 ­ 13 ) Scutellum V­shaped. Abdomen with numerous erect setae, surface of segments smooth. Sternum VII with lateral margins smooth, a weak depression in center. Pygidial surface smooth, lateral margins smooth, with long setae apically. Median lobe in lateral view smoothly curved ( Fig. 14 View FIGURES 14 ­ 20 ); apex pointed ( Fig. 15 View FIGURES 14 ­ 20 ); basal hood long, lightly sclerotized, with apodemes indistinct at lateral margins of hood; subbasal fenestra present; basal spurs prominent; tegmen triangular; apical sclerite small, hook shaped ( Fig. 16 View FIGURES 14 ­ 20 ).

Allotype: Female. Length 5.2 mm; color similar to male. Head with labrum, frons, clypeus, eyes and antennae similar to male; mouthparts similar to male. Prothorax distinctly wider than long, L/W = 0.57; pronotum as in male; evenly punctate on disc; with punctures separated by distance equal to or slightly greater than their own diameters. Lateral arm of prosternum and proepimeron as in male; prosternum similar to male, but with width of intercoxal process 1.17 x diameter of procoxa, broadened behind coxae, posterior angles slightly swollen, posterior margin straight and weakly crenulate. Mesosternum, metasternum and metepisternum as in male. Legs similar in form to male, and basal tarsomere of fore­ and middle legs not expanded. Elytra with punctation and apical intervals similar to male, but with short striae along basal margin of elytra; punctures behind humerus deep and rugose, a weak depression behind humerus. Scutellum V­shaped. Abdomen with segments VIII–XI forming elongate ovipositor ( Fig. 21 View FIGURES 21 ­ 32 ). Sternum VIII with long strap­like basal apodeme; only several setae remain of the apicolateral arms; dorsum of segment VIII with diagonal dorsal sclerites ( Fig. 23 View FIGURES 21 ­ 32 ). Hemisternites with long, thin basal rods, weakly sclerotized apically; paraprocts separated into pair of slender dorsal rods, apically forming hood­like projection above genital orifice ( Fig. 22 View FIGURES 21 ­ 32 ); baculum indistinct, apical, longer than gonocoxae. Gonocoxae short, robust, with long setae at apices; coxostyli very small, with several long apical setae. Spermatheca ( Fig. 29 View FIGURES 21 ­ 32 ) with duct and gland openings adjacent on swollen receptacle; spermathecal duct short, sclerotized, not coiled.

Etymology. This species is named for Jan Bechyné, who described the genus and played a key role in the systematics of Neotropical Chrysomelidae .
