( Figs. 1 View FIGURE 1 C, 4, 6, 7)

Diagnosis. Distinguished from other congeners by its rather small size, fuscous, subparallel-sided body, weakly shining dorsum, somewhat disarranged silvery, scalelike setae on hemelytron, and form of male genitalia.

Description. Body generally fuscous, subparallel-sided, weakly constricted (HCR more than 0.8); dorsal surface weakly shining, partly matt. Head with sparsely distributed, simple, semierect setae and short, scalelike setae; base of vertex with dark, stiff setae. Antenna pale brown; segment I more or less darkened at base; segment II weakly terete with reddish apical 1 / 3 − 1 / 2; segments III and IV dark brown, with pale extreme bases. Labium pale reddish brown, reaching base of mesocoxa; segment I and apical part of segment IV darkened. Pronotum somewhat roughened, with uniformly distributed, dark, short, semierect setae; pleura dark brown, pruinosed, with sparsely distributed, scalelike setae along posterior margin of epimeron; scutellum flat, shallowly and transversely rugose, sparsely with scalelike setae anterolaterally. Hemelytron partly matt anteriorly, with 2 somewhat zigzagged fascia of scalelike setae (posterior fascia sometimes more scattered) and with uniformly distributed, dark, simple, reclining setae; membrane dark smoky brown. All coxae, except for dark apical half of procoxa, creamy yellow; femur dark brown, partly reddish; bases of meso- and metafemora creamy yellow; tibia generally reddish brown; tarsi pale brown, except for each tarsomere III widely darkened. Abdomen shiny fuscous; lateral parts of abdominal sterna V and VI each with a bunch of scalelike setae. Male genitalia ( Figs. 6–7 View FIGURE 6 View FIGURE 7 ): Left paramere with rather broad dorsal protuberance. Endosoma nearly C-shaped, subapically with a bifurcate, somewhat flattened process.

Measurements. ♂/♀: Total body length 2.6−2.7 / 2.8−2.9; length from apex of clypeus to cuneal fracture 2.03−2.09 / 2.18−2.32; width of head across eyes 0.70−0.75 / 0.75−0.78; head height 0.52−0.60 / 0.60−0.64; width of vertex 0.35−0.36 / 0.36−0.42; lengths of antennal segments I −IV 0.18−0.20, 0.85−0.88, 0.36−0.38, 0.36 − 0.36 / 0.16−0.23, 0.76−0.89, 0.37−0.42, 0.37−0.41; basal width of pronotum 0.82−0.84 / 0.80−0.86; minimum width across hemelytron 0.75−0.78 / 0.74−0.81; maximum width across hemelytron 0.86−0.90 / 0.88 −1.00; and length of metatibia 1.34−1.44 / 1.32−1.42.

Etymology. From Latin, sub-parallelus, referring to the nearly parallel-sided, not much constricted body form.

Biology. No information is currently available, as all specimens were collected by light trap. Collection records suggest this new species has at least two generations per year.
