Specimen examined. [ CNU] Holotype : 1♂, Bach Ma National Park (16.2281, 107.8583), Loc Tri, Phu Loc distinct, Thua Thien Hue province, Vietnam, 21.vi.2023, by light trap, J. Jeon leg.; [ CNU] GoogleMaps Paratypes: 1♂ 1♀, same data as holotype; [ ZCDTU] GoogleMaps Paratypes: 2♂ 2♀, same data as holotype GoogleMaps .

Host. Unknown.

Distribution. Vietnam (Central).

Etymology. Named after combination of Latin words, ruber (red) and uniformis (uniform), referring to the almost uniformly reddish-brown coloration of dorsum unique within the genus Pseudoloxopidea .

Diagnosis. Recognized by the mostly reddish dark brown body with dense dark punctures, densely covered with silver and dark setae; head relatively large; compound eye width more than 1/2 vertex width in female; hemelytra mostly dark reddish brown tinged with sanguineous areas; inner part of cuneus with sanguineous marking; vein tinged with sanuineous apically; tibia entirely pale brown, without dark basal spots; left paramere sinuate with processes, sensory lobe narrow with serrated process, hypophysis narrow and vertically curved with basal process; right paramere rod-shaped with serrated projection subapically; endosoma sclerotized with one long and curved spicule, its apex tapered and sharp ( Fig. 2A–F View FIGURE 2 ).

Description. MALE: Body elongated-oval, length 3.01–3.07, mostly reddish brown with sanguineous parts. Coloration: Head: mostly pale brown with dark spots (from the punctures); vertex and frons brown; clypeus pale brown; juga and antennal socket with reddish markings; antennae mostly pale brown except for first segment; first segment mostly reddish brown, subapical part pale brown; labium entirely pale brown. Thorax: pronotum mostly brown, lateral margin slightly sanguineous; scutellum slightly paler than pronotum and hemelytra, with two reddish longitudinal stripes mesially; hemelytra mostly dark brown with sanguineous parts; clavus entirely dark brown; corium tinged with sanguineous except for posterolateral areas; embolial margin sanguineous; cuneus mostly tinged with sanguineous; membrane entirely grayish; veins tinged with sanguineous; legs mostly pale brown; apical parts of fore- and mid-femur with tiny reddish spots; hind-femur pale with reddish markings subapically; tibia entirely pale brown; tarsus entirely pale brown, except for dark claw. Abdomen: mostly brown with sanguineous area anteriorly. Surface and vestiture: body somewhat glossy, densely covered with two types of silvery and dark setae, with dense dark punctures; head punctate; vertex and frons glabrous; clypeus densely covered with dark setae; pronotum with dense dark punctures, sparsely covered with silvery and dark setae; scutellum sparsely punctate; hemelytra densely covered with silvery and dark setae, with dense dark punctures. Structure: Head: somewhat prognathous; vertex width more than single compound eye width; antennae linear, subequal to body length; first segment thickest, shorter than head length, subequal to single compound eye width; second segment much longer than combination of third and fourth segments; third segment longer than fourth segment; proportion of first to fourth antennal segments 0.3: 1.7: 0.6: 0.4; labium reaching apex of hind coxae. Thorax: pronotum trapezoid, longitudinal length shorter than 1/2 basal maximal width, posterior margin straight; calli slightly swollen; pronotal collar medial length shorter than first antennal segment diameter; scutellum somewhat large, anterior width longer than 1/2 basal pronotal width, longitudinal length more than pronotum longitudinal length, subequal to commissure; lateral margin of hemelytra almost straight; cuneus triangular, not elongate, anterior width subequal to cuneal length. Abdomen: rounded, not reaching to apex of cuneus. Genitalia: pygophore asymmetrical with concave and straight margins ( Fig. 2A View FIGURE 2 ); left paramere sinuate with serrated process and fin-liked process, sensory lobe narrow with serrated process, hypophysis vertically curved with process basally ( Fig. 2A, B View FIGURE 2 ); right paramere rod-shaped with serrated projection subapically ( Fig. 2A, C View FIGURE 2 ); endosoma membranous and largely sclerotized, with one spicule ( Fig. 2D, E View FIGURE 2 ); spicule long and curved, its apex tapered and sharp ( Fig. 2F View FIGURE 2 ).

FEMALE: No sexual dimorphism found. Body elongated-oval, length 3.34–3.42. Coloration: as in male. Surface and vestiture: as in male. Structure: as in male, except for wider vertex width and shorter compound eye width, vertex width subequal to 1.7x single compound eye width. Genitalia: not examined.

Measurements (in mm). Male (n=4)/Female (n=3) Body length, clypeus–apex of membrane: 3.01–3.07/3.34– 3.42; head length, excluding collar: 0.41–0.42/0.44–0.45; head width, including compound eyes: 0.82–0.84/0.85– 0.87; vertex width: 0.33–0.34/0.39–0.40; 1 st antennal segment length: 0.31–0.32/0.32–0.33; 2 nd antennal segment length: 1.71–1.73/1.73–1.75; 3 rd antennal segment length: 0.63–0.64/0.64–0.66; 4 th antennal segment length: 0.44– 0.45/0.45–0.46; total antennal length: 3.09–3.14/3.14–3.20; mesial pronotal length: 0.44–0.45/0.47–0.49; posterior pronotal maximal width (straight): 1.19–1.22/1.27–1.29; anterior scutellar width: 1.02–1.04/1.06–1.09; mesial

scutellar length: 0.65–0.67/0.69–0.72; commissure length: 0.64–0.66/0.68–0.70; maximal width across hemelytron: 0.65–0.66/0.70–0.72.

Remarks. This species is distinguished from another congener, Pseudoloxopidea pinicola Yasunaga, 1999 by somewhat larger and broader head; hemelytra and vein partly tinged with sanguineous; entirely pale tibia without any dark spots at the base of spine; a sinuate left paramere with processes, sensory lobe with serrated process, curved hypophysis with basal process; a rod-shaped right paramere with a serrated projection; and a sclerotized endosoma with a long and curved spicule.
