Description
. Body length
7.1–7.7 mm
. Head, pronotum, elytra, and abdomen mostly dark brown; apex of head reddish; lateral margins, suture, and apex of elytra reddish; abdomen reddish laterally and apically; antennae, palpi, and legs reddish; femora dark brown. Microsculpture very strong, isodiametric. Iridescence absent. Dull, without metallic luster.
Head
. Labrum strongly transverse, subtruncate anteriorly. Antennae subfiliform, very long: segment 1 (scape) moderately long, about 2x longer than its maximum width. Frontal furrows wide, shallow, convergent. Eyes strongly convex; two setiferous punctures on inner side of each eye. Tempora not inflated. Mentum: medial tooth entire, acute apically, moderately shorter than lateral lobes. Paraglossae membranous, prominent, about as long as ligula.
Thorax
. Pronotum slightly convex, impunctate, wrinkled across base, subquadrate, widest about middle; apex emarginate; anterolateral angles well developed, obtusely rounded; anterior bead incomplete, obsolete medially; sides moderately rounded, slightly sinuate posteriorly; lateral grooves very deep, very long (about as long as adjoining foveae); a single setiferous puncture on each side (posteriorly); posterolateral angles rectangular; posterolateral carinae blunt, very long (longer than adjoining foveae); laterobasal foveae well defined, impunctate, moderately deep, very wide, oblong, prolonged forward, simple; posterior bead absent; base emarginate, about as wide as pronotal apex and elytral base.
Legs
. Moderately long.
Elytra
. Moderately convex, subovate, widest about middle. Basal margin incomplete, reaching about interval 4. Shoulders obtuse. Sides moderately rounded. Scutellar striole obsolete. Striae almost complete, feebly impressed, shallow, finely punctate; stria 3 or interval 3 with three setiferous punctures. Recurrent stria long, sharp, directed apically toward stria 6. Intervals depressed. Sutural apices strongly rounded.
Abdomen
. Last visible sternum (sternum VII): male with two apical ambulatory setae; female with four apical ambulatory setae.
Aedeagus
. Lateral view (
Fig. 66
): unusually strongly arcuate, widest medially, narrowed in apical half; base strongly convex dorsally; middle strongly convex dorsally, strongly concave ventrally, with dorsal membranous area narrow (wide in other
Zolus
species
) and short; apex slender, moderately concave dorsally, slightly concave ventrally, with extreme tip unusually slender. Dorsal view: moderately wide, asymmetrical (ostium of membranous area deflected to right); apex straight; basal orifice narrow, closed anteriorly, very distant from membranous area. Parameres with four apical setae.
