Wolski, Andrzej, Gorczyca, Jacek, Yasunaga, Tomohide, indra, Zdenek & Herczek, Aleksander, 2018, Taxonomic review of the bifenestratus species group of the genus Fulvius Stal with descriptions of two new species (Hemiptera, Heteroptera, Miridae, Cylapinae), ZooKeys 796, pp. 107-129 : 107

Fulvius tumidipennis Wolski, Gorczyca & Yasunaga sp. n. Figs 9, 25, 26, 35-38

Diagnosis.

Eyes contiguous with pronotal collar (Figure 9); corium covered with dense setae, with yellow patches basally and apically (Figure 9). Male genitalia as in Figs 25, 26.

Remarks.

Fulvius tumidipennis is most similar to F. flavicornis and F. subnitens in having a yellow patch basally and apically on the corium (Figs 5-7), but it can be distinguished by the structures of the male genitalia.

Description.

Male. Coloration (Figure 9). Dorsal surface varying from brown to dark brown, with yellow and orange areas. Head. Dark brown; maxillary and mandibular plates sometimes slightly tinged with red; antennal segment I varying from reddish to dark brown; segment II dark brown, weakly tinged with red at basal one third, apical two thirds yellow; segments III and IV dark brownish; IV sometimes slightly yellowish apically; rostrum ranging from dark yellow to dark brown. Thorax. Pronotum. Ranging from brown to dark brown, almost black. Mesoscutum and scutellum. Varying from brown to dark brown. Thoracic pleura. Ranging from brown, sometimes slightly tinged with red to dark brown. Hemelytra. Clavus and corium with yellow patch basally and apically; corium with orange patch apically, contiguous with orange patch on apex of embolium; cuneus ranging from brown to dark brown; membrane brownish, sometimes tinged with gray. Legs. Mostly dull yellowish, often tinged with red; coxae usually paler than remainder of leg, yellow, slightly darkened apically; femora dull yellowish, often tinged with red; tibia and tarsus yellow, rarely darkened. Abdomen. Dark brown, usually tinged with yellow, rarely with red. Structure and vestiture (Figs 9, 35-38). Dorsal surface covered with dense, relatively long, almost decumbent setae. Head. Posterior margin of vertex with row of long, erect setae, present also on posterior margin of each eye; eyes slightly removed from pronotal collar; antennae covered with dense, semidecumbent setae; rostrum distinctly surpassing half of abdominal length, sometimes reaching apex. Abdomen. Apical portion of abdomen flattened ventrally. Male genitalia (Figs 25, 26). Left paramere (Figure 25). Apical process and paramere body forming obtuse angle; paramere body relatively thick, left margin convex in sinistrolateral view, arcuate, right margin weakly sinuate, concave; apical process when viewed sinistrolaterally with basal two thirds cylindrical and apical third weakly tapering toward apex, ventral margin with distinct subapical spine. Aedeagus (Figure 26). Endosoma tumid, membranous, divided into two, large lobes apically, sclerotized portion of ductus seminis inside endosoma relatively long, tapering toward apex.

Female. Similar to male in coloration, structure, texture, and vestiture.
