Fingulus rubricatus Yasunaga & Yamada, n. sp.
(Figs. 2 A–B, 3D, 4C)
Diagnosis. Recognized readily by its carmine red general coloration. Most closely related to F. atrocaeruleus Distant known from Australia, based on similarity in the shape of the left paramere; easily distinguished by its larger size, carmine red general coloration, punctate pronotal collar, and longer antennal segment II greater than basal width of pronotum.
Description. Holotype Male: Body generally carmine red, comparatively large in size; dorsal surface shining, with densely distributed, fuscous punctures. Head shining, impunctate, longer than width across eyes; vertex narrowly darkened on basal carina; tylus moderately produced, slightly deflexed medially; neck inflated posteriorly to eyes. Antenna uniformly pale brown, except for wholly shiny carmine segment I that is about as long as an eye in dorsal view. Labium pale brown, reaching between mesocoxae; apex of segment IV dark brown. Pronotum including collar punctate; calli shiny, smooth, slightly infuscate mesially; mesoscutum fuscous, matte; anterior margin of scutellum narrowly darkened, slightly elevated above surface of hemelytron; pleura almost entirely fuscous, with dusty reddish white ostiolar peritreme; propleuron and epimeron punctate; episternum ventrally dark red, transversely wrinkled. Hemelytron weakly rounded laterally, not much slanted at cuneal fracture, with uniformly distributed punctures except on smooth cuneus; clavus narrowly infuscate along claval commissure; anterior inner corner of cuneus fuscous; membrane pale grayish brown, semitransparent, roundly suffused with fuscous along posterior margin of dark veins. Coxae and legs red; procoxa, all trochanters and bases of all femora creamy white; more than half apical part of each tibia and all tarsi whitish brown. Abdomen shiny fuscous. Male genitalia: Left paramere with sensory lobe rounded; hypophysis rather short, flattened and weakly curved, with bifurcate apex (Fig. 4 C). Structure of endosoma could not be confirmed well, as the single available specimen seems not to have been sexually matured. Female: Unknown.
Measurements. ♂: Total body length 3.92; length of head 0.68; width of head across eyes 0.62; width of vertex 0.11; lengths of antennal segments I −IV 0.47, 1.64, 0.87, 0.70; length of labium 1.43; mesal length of pronotum including collar 1.05; basal width of pronotum 1.24; maximum width across hemelytron 1.35; and length of metafemur, tibia and tarsus 1.26, 1.84, 0.31.
Etymology. From Latin, rubricatus (= red colored), referring to the bright red coloration of this new species. Biology. Unknown; only a single male was collected at UV light trap.
