Mycetocylapus minor Poppius 1914: 126

Mycetocylapus major: Bergroth 1920: 73 ; Carvalho 1956: 16, 1957: 32, Schuh 1995: 31; Gorczyca 2006: 54

Diagnosis. Most closely related to M. major , but can be easily distinguished by the smaller body and with a scutellum without pale stripes laterally ( Fig. 2 E)

Redescription. Male. COLORATION ( Fig. 2 E). Dorsal surface yellow, with brownish and reddish areas. Head. Almost entirely yellow; gula with brownish patches bordering ventral margin of each eye; antenna yellow with reddish and brownish areas; segment I entirely yellow, sometimes tinged with red apically; segment II yellow with brownish rings: one situated slightly beyond base, second occupies apical one-third; segments III and IV brownish; rostrum yellow; apical two-thirds of segment IV brownish. Thorax. Pronotum. Yellow, brownish along lateral margins. Mesoscutum and scutellum. Mesoscutum apparently paler than scutellum, dull yellowish brown; scutellum brownish with hardly visible, small, yellowish areas. Thoracic pleura. Proepimeron yellow, slightly darker than pronotum; remaining pleura dark brownish, sometimes slightly tinged with yellow; evaporative areas and peritreme contrastingly pale yellow. Hemelytron. Varying from yellow with large pale brownish red patch on apex of corium to dull yellowish with clavus and basal portion of corium pale brownish and with large, reddish patch apically; cuneus with reddish stripe along its inner margin, sometimes occupying almost entire surface of cuneus. Legs. Yellow; tibiae slightly darker than other segments. Abdomen. Yellow, more or less distinctly tinged with red or brown. STRUCTURE AND VESTITURE ( Figs. 2 E, 5C–F). Head. Rostrum reaching abdomen medially. Thorax. Pronotum. Anterior lobe not distinctly narrowed; posterior lobe of pronotum, smooth. Hemelytron. Shallowly and sparsely punctate.

Male genitalia ( Fig. 6 ). Sclerotized portion of ductus seminis inside endosoma relatively long; endosoma with single, broad sclerite, distinctly narrowed, nearly pointed apically.

Female. Unknown.
