Biology. Unknown. All the specimens were collected at night attracted to a light trap (bulb “ MIX ” - type 250 W, E 40) in the ecotone zone of the rainforest (see Malipatil et al. 2022, Fig. 8).

description
Description. Female. Body ellipsoidal, dorsoventrally flattened, length 3.2 mm (Figs 1, 2 A, C). Coloration. Body generally fuscous (Fig. 1 A). Eyes silver-reddish. Apical part of fourth antennomere brownish. Labrum brown; labium yellowish-brown, fourth segment darker in distal part. Hemelytral membrane smoky brown. Legs yellow except coxa black (Fig. 1). Abdomen black. Surface and Vestiture. Body shining, impunctate, slightly rugose, with uniformly distributed, dense, short, pale pubescence (Figs 1 A, 2 A, B); head with delicate erect pubescence, vertex and buccula with long, reclining setae (Fig. 2 A – D); antennae with adherent and erect setae; thoracic pleura partially glabrous (Fig. 2 A); coxae with dense patches of hairlike microtrichia; profemur with long yellow setae; tibia with yellow setae and rows of short dark spines; abdominal segment IX with long, brown setae (Fig. 1 B). Structure. Head: short and oblique, somewhat porrect, eyes removed from anterior margin of pronotum, lacking sensory setae, and with ommatidia flat (Fig. 2 B); vertex weakly carinate posteriorly; neck-like occipital region present; buccula narrow, parallel-sided (Fig. 2 D). Antenna: inserted at ventral margin of eye, antennomere I short, weakly thickened, subconical, II thick, fusiform, antennomeres III and IV thinner than II, fusiform, combined length, shorter than II. Labium: thick and very short, not exceeding middle of procoxa; segment I very short, almost completely retractable under clypeus, subequal in length to buccula (Figs. 1, 2 B, C). Thorax: pronotum trapeziform, short, lateral margins without carina, posterior margin deeply concave; calli barely visible; propleuron covering almost entire procoxa (Figs 1 B, 2 C); mesoscutum largely exposed; scutellum flat. Metathoracic spiracle visible. Metathoracic scent efferent system: evaporatory area triangular; ostiolar peritreme large, tongue-like. Mesosternum greatly enlarged, shieldlike. Metasternum narrow, subrectangulate. Hemelytron generally flat; lateral margin rounded; cuneus distinct, weakly reflexed at costal fracture; single membrane cell (Figs 1 A, 2 A). Legs: short; procoxae cylindrical, contiguous medially; pterothoracic coxae in close proximity; femora robust, femoral trichobothria very short, without trichome; spiculae present (Fig. 1 E); tibia short, slightly longer than femora; tarsi expanded distally; hindtarsal tarsomeres I and II subequal in length, together equal to tarsomere III (Fig. 2 F); claws broad, angulate, strongly toothed at base; parempodia broad, lamellate, strongly convergent distally; pulvillus triangulate, well-developed (Fig. 2 G, H). Abdomen: as wide as hemelytron. Genitalia: as in Fig. 3; bursa copulatrix membranous with weakly distinct elements; seminal depository large; sclerotized rings thick-rimmed, with distinct lateral infoldings; gonapophysis 9 ramus toughened, without an inner, triangular process anterodorsally; gonapophyses 8 and 9 serrate, gonapophyses 8 with apex sharpened, gonapophyses 9 with apex blunt. Measurements (in mm) (n = 3). Body. Length, clypeus-apex of membrane: 3.20; width: 1.26. Head. Length in dorsal view, excluding collar: 0.42; width, including compound eyes: 0.88; interocular space: 0.50; eye dorsal width: 0.20; length in dorsal view: 0.29. Antenna. Length of antennomeres: I: 0.21; II: 0.40; III: 0.25; IV: 0.26. Labium. Total length: 0.68; length of segment I: 0.16; II: 0.19; III: 0.15; IV: 0.21. Pronotum. Mesal length: 0.49; posterior maximal width (straight): 1.11. Mesoscutum. Mesal length: 0.21. Scutellum. Anterior width: 0.62; mesal length: 0.52. Hind leg. Femur length: 0.75; femur width 0.27; tibia length: 0.86; tarsus length: 0.24; length of tarsal segment I: 0.07; II: 0,06; III: 0.14. Hemelytron. Claval commissure: 0.44; heme length: 2.22; corium length: 1.31; outer cuneal margin length (straight): 0.41; cuneus width: 0.54.
diagnosis
Diagnosis. Readily distinguished from congeners by the following combination of characters: body shape ellipsoidal, pronotum more than twice as wide as long, pro- and metafemur without robust spines and all legs yellow. Sclerotized rings thick-rimmed, with distinct lateral infoldings; gonapophysis 9 ramus toughened, without an inner, triangular process anterodorsally.
