 Description. Body length: males 7.35–7.45 mm (holotype 7.35 mm); females 7.30– 9.10 mm.   
Male. Body flattened, subparallel, glabrous. Head yellow, base with dark collar, well visible behind eyes and disappeared behind vertex. Antennomeres 1–3 yellow, antennomeres 4–5 gradually darkened, remaining antennomeres black. Pronotum yellow with five small brown spots (two on disc and very small median one and two larger lateral ones before base). Scutellum yellow. Elytra yellow with narrow, parallel-sided metallic green stripe extending from humeral callus to before apex; suture in posterior two thirds and apical angle of elytra narrowly darkened. Prosternum yellow. Mesosternum yellow, sometimes darkened medially. Metasternum and abdomen black. Legs yellow, all femora and tibiae with black stripes on outer side, bases of procoxae usually also darkened, all tarsi dark brown to black.  
Labrum transverse, anterior part covered with several long pale setae, anterior margin slightly concave. Anterior part of head semiopaque, almost glabrous, only anterior part of clypeus with long pale setae, several setae also in front of antennal insertions. Frontal tubercles semiopaque, large, subtriangular, slightly elevated, covered with microsculpture, separated from each other by distinct furrow. Interantennal space as wide as transverse diameter of antennal insertion. Vertex semiopaque, covered with fine punctures, glabrous, with only one long pale seta behind each eye. Antennae filiform, 0.90 times as long as body, length ratios of antennomeres 1–11 equal to 14-5-8-17-14-15-15-15-14-13-15.  
Pronotum tranverse, 1.70–1.80 times as broad as long, widest at anterior third. Surface lustrous, covered with very small punctures, glabrous, moderately convex, with two longitudinal lateral depressions and impressed median line. All margins distinctly bordered. Anterior margin moderately concave, posterior margin almost straight in middle and rounded on sides. Lateral margins rounded anteriad, nearly straight, convergent posteriad. Anterior angles acute, rounded, slightly produced anteriad, posterior angles obtusely angulate. All angles with setigerous pore bearing one long pale seta.  
Scutellum triangular with rounded apex, lustrous, glabrous, covered with microsculpture.  
Elytra lustrous, slightly divergent posteriad, almost glabrous, posterior quarter scarcely covered with very short, indistinct setae. Humeral calli well developed. Elytral surface covered with small and very dense confluent punctures. Epipleura broad in anterior fourth, gradually narrowed towards apex. Macropterous.  
Ventral surface semiopaque, finely punctate and covered with pale hairs. Last ventrite feebly impressed in middle, posterior margin nearly straight.  
Hind tarsomere 1 as long as two following tarsomeres combined. Aedeagus as in Fig. 19.  
Female. Last ventrite widely subtriangular. Abdomen robust. Spermatheca as in Fig. 16.  
 Variability. Brown spots on pronotum sometimes smaller or missing. Elytral pattern variable, with the metallic green stripe in dark specimens broader, slightly divergent posteriad and reaching the apex.   
 Differential diagnosis. Mimastra jelineki sp. nov. resembles M. limbata Baly, 1879, M. kremitovskyi sp. nov., M. maai and M. malvi in the presence of the longitudinal metallic stripe on the elytra. This stripe is, however, very narrow (other species have the stripe much broader and usually covering most of the disc with only elytral margins remaining pale). Moreover, M. limbata differs by the hook-shaped protarsomere in male.   
 Etymology. Dedicated to Josef Jelínek (Czech Republic, Prague), an excellent specialist in Nitidulidae.   
 Biology. Unknown.   
 Distribution. Indonesia: Java and Bali.
