( Figs 102–104 , 120 , 126A , 128A , 130 , 134 ) Etymology The specific epithet refers to Malaysia , terra typica of this species. Diagnosis The species belongs to the lawrencei species-group, and so is distinguishable from the other Scolytocis by the smooth posterior margin of pronotum and the concave prosternum. It differs from all the other species in this group by the surfaces of the prosternum, metaventrite and abdominal ventrites, which have a distinct microreticulation in high relief. Description Holotype . ( Fig. 102–104 ) Measurements in mm: TL 1.05; PL 0.42; PW 0.42; EL 0.63; EW 0.47; GD 0.47. Ratios: PL/PW 1.00; EL/EW 1.33; EL/PL 1.50; GD/EW 1.00; TL/EW 2.22. Body black; antennae, mouthparts and legs dark yellowish brown. Head sparsely punctate; punctures shallow, interstice finely microreticulate. Each antenna ( Fig. 126A ) with nine antennomeres (FL 0.068mm ; CL 0.125mm ; CL/FL 1.85); length of the antennomeres (in mm) as follows: 0.060; 0.028; 0.030; 0.013; 0.013; 0.013; 0.033; 0.038; 0.055. Eyes with greatest width 1.2X the basal width of scutellum. Pronotum with coarse, sparse, shallow punctation; puncture irregular, separated by a distance of two to three puncture widths, interstice conspicuously microreticulate; anterolateral margins straight; posterolateral angles broadly rounded; posterior margin without a rugose border. Scutellum impunctate; basal width 0.16X the EW. Elytra with subseriate punctation; punctures coarser and shallower than those of pronotum; border of punctures indistinct, interstice slightly rugose; elytral apex rounded, glabrous, its declivity with a weak concavity, cuticular globules absent. Each hindwing ( Fig. 120 ) with apical area without conspicuous pigmented lines. Prosternum concave, without longitudinal carina; surface with distinct rugosity. Metaventrite glabrous, finely rugose; discrimen one-fourth the length of the metaventrite at midline. Abdominal ventrites glabrous, rugosity similar to that of prosternum and metaventrite. Each metatibia ( Fig. 128A ) near 3X as long as broad; outer apical and outer lateral edges forming an almost perpendicular angle that is rounded; outer edge with spines (around 15) regularly distributed at apical two-thirds, then getting sparser. Male genitalia (in a paratype ). ( Fig. 130 ) Genitalia barely sclerotized; apex of tegmen acute; median lobe extremely membranous and elongate, around 1.8X longer than tegmen. Type series Holotype .

Variation Measurements in mm (n = 5, including the holotype ): TL 1.00–1.16 (1.08 ± 0.06); PL 0.37–0.42 (0.40 ± 0.03); PW 0.42–0.47 (0.43 ± 0.02); EL 0.63–0.74 (0.66 ± 0.05); EW 0.42–0.53 (0.47 ± 0.04); GD 0.42–0.47 (0.44 ± 0.03). Ratios: PL/PW 0.88–1.00 (0.93 ± 0.07); EL/EW 1.20–1.56 (1.41 ± 0.14); EL/PL 1.50–1.86 (1.66 ± 0.16); GD/EW 0.89–1.00 (0.94 ± 0.06); TL/EW 2.10–2.44 (2.30 ± 0.14). Distribution Known only from Malaysia ( Fig. 134 ). Host fungi Ganoderma sp. (Ganodermataceae) , Phellinus sp. (Hymenochaetaceae) . Comments The placement of this species in the lawrencei species-group is justifiable, since it resembles other species of the group not only by external morphological features but also by the morphology of male genitalia (compare Figs 78 and 130 ).
