The holotype is card-mounted, complete, except detached genital capsule and right metatarsomeres II + III glued to the same piece of card. The original locality label is quite illegible; the data were reconstructed with help of Novák (2018), and replacement locality label is provided.

Description. Colouration (Figs 88–89). Body above and below, including posterior portion of pygophore, black, except clavus and corium dark brown; connexival segments ventrally with narrow brown stripe sublaterally; acetabula and peritremal surface brownish; antennomeres I–III pale brown, distiflagellum (IV) pale ochraceous; legs brown, femora apically darker; labium and base of pygophore pale ochraceous. Apex of scutellum with large yellowish spot, smaller yellowish callosities on apices of humeral angles, at the end of median furrow on corium, and anterolaterally on metepimeron; dorsal surface of body, especially on corium, with very small yellowish ochraceous callosities. Membrane dark brown, translucent.
Integument and vestiture. Body shining, clavus, corium and evaporatorium matt. Body above covered with dense, coarse, black punctures, except impunctate apex of scutellum; endocorium with punctures sparser but equally large as on exocorium; disc of pronotum (posteromedially) and scutellum (anteriorly) with prominent transverse wrinkles (Fig. 88); head underside and thoracic sterna with dense, coarse punctures; surface of abdominal sternites smooth with fine punctures.
Structure. Head (Fig. 12). Head slightly shorter than wide (length: width ratio 0.79–0.88). Mandibular plates with lateral margins distinctly sinuate in front of eyes above the large antenniferous tubercle, parallel-sided about their midlength, and narrowly rounded anteriorly; mandibular plates not meeting anteriorly, apex of clypeus completely free, apical incisure in front of clypeus wide, trapeziform.Antennomeres from shortest to longest: I <IIa <IV <IIb = III, but ratios of antennal segments highly variable. Scape (I) surpassing apex of head of about its halflength, basipedicellite (IIa) distinctly (1: 1.41‒1.93×) longer than scape and usually shorter than distipedicellite (IIb) (length of IIa: IIb ratio: 1: 1.00‒1.70). Labiomeres from shortest to longest (n = 1): IV (1.23 mm) <I (1.57 mm) <III (1.86 mm) <II (2.06 mm). Labium reaching posterior margin of mesocoxae.
Pronotum (Fig. 88). Lateral tooth on anterolateral angles prominent, directed laterad (Fig. 12). Lateral pronotal margin anteriorly slightly serrate. Humeri rectangular, slightly surpassing laterad over base of corium. Posterior margin slightly concave.
Scutellum (Fig. 88). Disc of scutellum convex in prefrenal portion, its postfrenal portion flat; apex narrowly rounded.
Hemelytra. Costal margin of corium only slightly insinuated basally (Fig. 88).
Thorax. Ostiole large, oval, opening posteriad; median furrow short and wide, not apparent in apical half of peritreme length (Fig. 18). Metasternum medium wide (Fig. 25).
Male genitalia. Genital capsule (Figs 90–94) nearly quadrangular in dorsal/ventral view, longer than wide. Ventral rim deeply incised medially, sharp (Fig. 93); posterolateral projections prominent (Figs 93, 94); ventral rim infolding not visible (Fig. 91). Superior processes of dorsal rim elongate, crescent-shaped (Figs 90–91, 96). Proctiger trapezoid, short, without any constriction (Fig. 95). Parameral socket open (Fig. 91: ps). Paramere (Figs 97–101): basal process (bp) with a lamellate, horizontally oriented semicircular lobe, apically with group of few long setae (Figs 97, 101); apical process (ap) hook-shaped, apically more pointed (Figs 97–99); mesal angle of stem without any additional projection (Figs 97, 99, 101). Phallus (Figs 102–105): A pair of dorsal conjunctival processes (dlc), transversely placed and ending in triangular sclerotised processes (Fig. 105); median penial plates (mpp) or processes of aedeagus fused basally, outer margins broadly and thickly sclerotized, encircling short, curved aedeagus (Fig. 105: ad).
Female genitalia (Figs 32, 36). Laterotergite VIII (lt8) subtriangular. Laterotergites IX (lt9) widely rounded apically, not touching each other medially, segment X visible (Fig. 32). Valvifers VIII (vf8) quadrant with median margins juxtaposed and dorsal margins slightly concave (Fig. 32). Valvifers IX (vf9) fused medially, with indistinct median fusion line, flat. Ring sclerites roughly circular, not apparently sclerotized in the specimen examined (Fig. 36). Spermatheca: dilation in the examined specimen swollen, whitish and not transparent, constricted subbasaly with sclerotized ring (Fig. 33), distal invagination (‘sclerotized rod’; Fig. 33) visible only basally, strongly curved; distal flange (df) tightly attached to apical receptacle (ar) (Fig. 36); apical receptacle subhemispherical (Fig. 36) with one long projection directed proximad and nearly reaching proximal flange (pf), and one short processes directed proximad and reaching distal flange.
Measurements (mm). See Table 2. Holotype (♂): Body length 19.27; head: length 3.43, width (including eyes) 3.92, interocular width 2.45; lengths of antennomeres: I—1.47, IIa—2.35, IIb—2.94, III—2.75, IV—2.45; pronotum: length 4.51, width (across humeri) 10.39; scutellum: length 6.96, width (across basal angles) 5.88; abdomen width (across segment III) 10.69.
Variation. Distribution of small yellowish callosities on dorsal surface of body varies among specimens. Ratios of length of antennomeres IIa to IV highly variable, arranged from shortest to longest: I <IIa <IV <III <IIb (3 specimens), I <IIa = IIb <III (IV missing; 1 specimen), I <IIa <IIb <III (IV missing; 1 specimen), I <IIa <IV <IIb <III (2 specimens), I <IIa <IV <IIb = III (2 specimen), I <IV <IIa <IIb = III (1 specimen).
Differential diagnosis. See key and Table 3. This species is easy to recognize due to its apically free clypeus, scape surpassing apex of head, and blackish-brown colouration with conspicuous whitish unpunctured spot at the apex of scutellum.
Etymology. We are pleased to dedicate this elegant new species to our dear colleague, Professor Jocelia Grazia, with our thanks for her outstanding contributions to pentatomoid systematics, morphology and phylogeny. Distribution (Fig. 139). Peninsular Malaysia (Kelantan, Perak).
