Sulawesifulvius thailandicus Wolski, Yasunaga & Gorczyca

Wolski, Andrzej, Yasunaga, Tomohide, Gorczyca, Jacek & Herczek, Aleksander, 2017, Sulawesifulviusthailandicus - a new species of the genus Sulawesifulvius Gorczyca, Cherot & Stys from Thailand (Hemiptera, Heteroptera, Miridae, Cylapinae), ZooKeys 647, pp. 109-119 : 110-112

Sulawesifulvius thailandicus Wolski, Yasunaga & Gorczyca sp. n. Figures 2-4, 12-17, 18-21, 22-25

Diagnosis.

Recognized by the following set of characters: dorsum yellow with large dark brown and red areas (Figs 2-3); parameres as described below and depicted in Figs 14-17; endosoma with three well-developed sclerites (Fig. 13).

Sulawesifulvius thailandicus is most similar to Sulawesifulvius schuhi and Sulawesifulvius yinggelingensis in having large red markings on the dorsal surface (Figs 2-3, 20, 23; Mu and Liu 2014) (only slightly tinged with red in Sulawesifulvius indicus ) ( Yeshwanth and Chérot 2015). Sulawesifulvius thailandicus can, however, be easily distinguished by the characteristic shape of the parameres (as depicted in Figs 14-17) and the endosoma with three endosomal sclerites (Fig. 13).

Description.

Coloration (Figs 2-4, 22-25). Dorsum yellow extensively mottled with dark brown and red. Head. Ground coloration yellow; vertex and frons moderately tinged with brown; vertex with two blackish patch posteriorly, each bordering inner margin of eye; tubercles on vertex and frons each with small dark brown patch; mandibular and maxillary plates and clypeus tinged with red; mandibular plates with two small, dark brown patches basally; antennal segments I and II yellow broadly tinged with red; segment dark brownish; labium dirty yellow tinged with red. Thorax. Pronotum. Yellow broadly tinged with brown and red; calli tinged with black. Mesoscutum and scutellum. Mesoscutum dark brown with small yellow tinges; scutellum mostly yellow, dark brown basally, with brown triangular pattern apically and with small, brown, longitudinal patch at extreme apex. Thoracic pleura. Proepimeron yellowish, weakly tinged with red; mesepimeron and metepisternum dark castaneous; scent gland evaporative area dirty yellow. Hemelytron. Yellow, extensively tinged with dark brown, brown, and red; apical half of exocorium and basal portion of cuneus with marking composed of black, longitudinal, curved patches bordering R+M vein and inner half of basal margin of cuneus (Fig. 2, arrow); membrane fuscous mottled with yellow. Legs. Dirty yellow with dark brown, brown and red tinges. Abdomen. Dark brown. Structure, Texture, and Vestiture (Figs 2-4, 18-25). Head. Vertex and frons each with pair of relatively large tubercles; labial segments I and II subdivided. Pronotum. Calli small. Mesoscutum and scutellum. Scutellum flat.

Male genitalia (Figs 12-17). Genital capsule (Fig. 12). Weakly flattened dorsoventrally; dorsal wall long, only weakly shorter than ventral wall; proctiger narrow; genital opening terminal in orientation; lateral margin immarginate. Aedeagus (Fig. 13). Ductus seminis relatively broad and rather short; sclerotized part of ductus seminis inside endosoma (dss) ovoid; secondary gonopore clearly present; endosoma with three sclerites (es1, es2 and es3); each sclerite sharply pointed; es1 nearly cylindrical at basal three fourths, apical one fourth tapering toward apex; sclerites es2 and es3 strongly curved; es2 tapering toward apex; es3 weakly broadened apically. Right paramere (Figs 14-15). Apical process relatively short, tapering toward apex, with protruding, hook-shaped process subapically; paramere body broad, covered with relatively long, semierect setae dorsally; basal process triangular. Left paramere (Figs 16-17). Apical process strongly broadened toward apex, with protruding hook-shaped process apically; paramere body long and thin, its lateral margins sinuate; sensory lobe and basal process strongly developed, elongated, tapering toward apex and sharply pointed
