Description. Length 3.5–5.5 mm, width 1.5–2.1 mm. General color brown, sometimes lateral margins of pronotum darkened; elytra with two pairs of transverse dark stripes near base and behind middle, widened towards lateral margin (Fig. 13 E), reduced in some individuals (Fig. 13 F). Antenna filiform, antennomere I not modified in males (Fig. 15 A), length ratios of antennomeres I–XI 1.0: 0.4: 0.5: 0.8: 0.9: 0.8: 0.9: 0.8: 0.8: 0.8: 0.8, length to width ratios of antennomeres I–XI 4.2: 2.1: 3.2: 4.8: 5.5: 5.4: 5.5: 5.5: 5.5: 5.1: 6.0; relatively slender than female (Fig. 15 B), length ratios of antennomeres I–XI 1.0: 0.3: 0.6: 0.8: 0.8: 0.8: 0.8: 0.8: 0.8: 0.8: 0.8, length to width ratios of antennomeres I–XI 4.5: 2.0: 3.3: 4.9: 4.7: 4.9: 5.1: 5.0: 5.0: 4.7: 4.9. Elytra 1.8 x longer than wide, surface sparsely mixed with short, elongate, erect, yellowish brown setae, and fine punctures. Apical margin of last abdominal ventrite with two well developed incisions in male (Fig. 15 G); slightly depressed in female (Fig. 15 H). Penis (Figs 15 C–15D) slender, 8.5 x longer than wide, gradually narrowed towards apex; apex of dorsal surface with deep notch below ventral surface; apex of ventral surface with shallow notch; slightly curved in lateral view, apex with deep notch between dorsal and ventral surface; ventral surface smooth. Internal sac with median endophallic spiculae short, about 0.5 x as long as penis, apex tapering and ventrally curved in lateral view, with two elongate spiculae at middle, apices rounded; five pairs of longitudinally oriented, tapering spiculae at base, basal pairs well sclerotized and others weakly sclerotized. Gonocoxae (Fig. 15 E) extremely slender, 7.6 x longer than wide, sides narrowed at apical 1/10; apices narrowly rounded; inner margins approximate from apex to midpoint, apex with nine setae; extremely slender from midpoint to base but abruptly widened at base. Ventrite VIII (Fig. 15 F) well sclerotized; spiculum elongate; apex square, apical margin truncate, with dense short setae; disc with several elongate setae at sides. Receptacle of spermatheca (Fig. 15 I) as wide as pump, narrowly separated from pump; pump strongly curved and apically narrowed; proximal spermathecal duct short, distinctly narrower than receptacle, apically widened, shallowly projecting into receptaculum.
Differential diagnosis. See diagnosis Doryscus luzonensis sp. nov.
Remarks. Seven specimens collected from the Philippines were misidentified as Doryscus testaceus by Weise (1924). They are members of D. luzonensis sp. nov. and D. mindanaoensis sp. nov., respectively.
Etymology. This new species is named for its type locality.
Distribution. Philippines (Mindanao).
