Bechyné (MPEG). Length: 11mm( holotype); 11–13mm( paratypes) General integument ( Figs 43, 44) dark-brown, some specimens slightly dark reddish-brown; legs and antennae clearer, anterior margin of frons with black contour. Pubescence yellowish, long and moderately dense, masking integument. Frons ( Figs 43, 44) elongate, widened and rounded anteriorly; very prominent, surpassing frontoclypeal region; convex; punctation moderately coarse and dense. Antenna ( Figs 12, 43, 44) surpassing hind angles of pronotum by one segment in male, slightly shorter in female; narrow, subserrate with 11 antennomeres; with longitudinal median carina in both sexes; 3rd antennomere slightly narrower and shorter than 4th. Pronotum ( Figs 13, 43, 44) wider than long (including hind angles), trapezoidal; strongly convex anteriorly, declivous posteriorly from base of hind angles to posterior margin; fore angles prominent; hind angles slightly divergent and strongly carinate; carina near internal margin of hind angles. Prosternum ( Figs 15, 44) moderately convex; punctation moderately coarse, denser near middle. Prosternal spine ( Figs 14, 15) wide and flat between procoxae, compressed laterally near apex; apex rounded directed dorsally with small subapical sharpened tooth. Hypomeron sparsely punctate; smooth at base. Pronotosternal suture ( Figs 15, 44) very wide; prosternal groove well developed. Mesosternal cavity ( Figs 14, 15) V-shaped with borders very wide at base, narrowed apicad; borders raised and horizontal on basal half, vertical near middle and slightly declivous at base. Mesepimeron and mesepisternum forming part of margin of mesocoxal cavity. Metasternum slightly raised between mesocoxae behind mesosternal cavity. Metacoxal plate ( Figs 16, 44) moderately narrowed laterally; free margin with well developed rounded tooth. Tarsomeres 1–3 ( Fig. 44) lamellate beneath in all legs; tibial spurs well developed. Scutellum elongate, slightly narrowed apicad; apex rounded. Elytra ( Figs 43, 44) strongly convex, gradually narrowed apicad; striae weakly marked by row of punctures; apex sharpened with a tiny distal spine. Male. Tergite VIII ( Fig. 18) almost as wide as long, slightly narrowed apicad; distal margin rounded; translucent mediobasally and marginate by fringe of setae of varied sizes. Sternite VIII ( Fig. 19) transverse, bandlike, translucent with one C-shaped yellowish band each side; anterior margin straight; fore angles rounded; setae moderately long on distal third. Sternite IX ( Fig. 17) elongate, basal margin truncate with rounded angles; narrowed on distal third; setae moderately long on distal half. Tergite IX ( Fig. 20) transverse, narrowed apicad; coarsely punctate laterally; distal margin deep- and widely V-shaped emarginated at middle; distal angles rounded and densely setose with long setae. Tergite X almost as long as wide, slightly narrowed apicad; sparse and moderately long setae forming irregular transverse band near middle. Aedeagus ( Figs 21, 22) 2.4 times longer than wide; basal piece long, 0.8 times length of parameres dorsally; parameres with apex cuneiform; cuneiform area with lateral margins rounded, basal angles prominent and rounded and distal angles narrowed; with long dorsal and ventral setae and ventral; median lobe (excluding basal struts) almost as long as parameres dorsally; slightly constricted at base and gradually narrowed apicad; wider area as wide as parameres (dorsally) at base.   Etymology. The specific epithet is a derivative of the Latin word  nigellus(=darkened) referring to the integument.   Paranoplischius nigellus  sp. nov.differs from  P. modestus  sp. nov.especially by (  P. modestusin parentheses): integument dark-brown (reddish-brown); frons elongate (frons as long as wide), hind angles of pronotum divergent (directed posteriorly); apex of prosternal spine rounded and directed dorsally with small subapical tooth (apex rounded with subapical tooth directed ventrally); borders of mesosternal cavity very wide (borders slender).
