Diagnosis. Z. westerduijni sp. nov. is distinguishable from all other species of the genus by the almost entirely black body. It also differs from other species by the slightly angulate postcoxal line and the extremely narrow penis, about 50 times longer than wide, typically 35–40 times in other species of the genus.

Description of holotype, male. Length 4.0 mm; width 3.4 mm. Body oval, rounded, convex ( Figs. 18–19 ). Head and pronotum black, latter with narrow yellow stripe on anterior border; antennae and mouthparts brown, apex sometimes darker; pubescence grayish white, short, irregularly distributed ( Fig. 20 ). Prothorax black; pubescence light brown, short. Scutellar shield black. Elytra entirely black, shiny; pubescence light brown except for central area, with inconspicuous dark-brown pubescence; this pubescence lacking in some areas, probably due to rubbing ( Figs. 18–21 ). Epipleuron black, inner carina extending more than half distance to outer margin. Meso- and metaventrite brown. Legs brown. Abdominal postcoxal line curved posterolaterally, reaching posterior margin of ventrite for short distance, then redirected anteriorly toward base of ventrite in lateral third ( Fig. 22 ). Posterior margin of ventrite V with smooth notch. Posterior margin of ventrite VI with deep triangular emargination ( Fig. 23 ). Phallobase short, half length of tegminal strut, two times longer than wide ( Fig. 24 ). Penis guide triangular in dorsal view, two times longer than wide, with rounded apex ( Figs. 25–27 ); in lateral view, triangular in basal 3/5, parallel-sided and narrow in distal 2/5 ( Figs. 28–29 ). Penis guide projecting beyond parameres ( Fig. 25 ), parallelsided in ventral view, slightly projected apically ( Fig. 27 ); regularly curved in lateral view and tapering from base to apex, the latter with small truncated widening ( Figs. 28–29 ). Sparse, very short setae at end of paramere ( Fig. 29 ). Penis narrow, more than 50 times longer than wide, semicircular in basal third, gently curved in middle third, and straight in apical third ( Fig. 30 ), ending in pointed apex, membranous areas in distal 1/20 of apex, on lower side ( Fig. 31 ); inner branch of penis capsule slightly curved inward and truncated, outer branch subtriangular, tapered with hook, inconspicuous membranous projection on outer margin ( Fig. 30 ).
