Mycetocylapus pacificus: Carvalho & Lorenzato 1978: 124 , Fig. 10 ; Carvalho & Froeschner 1987: 184; Schuh 1995: 31; Gorczyca 2006: 54

Diagnosis. Distinguished by having the following combination of characters: dorsum dark, reddish or castaneous; antenna dark; pronotum with distinct, pale, longitudinal stripe medially; anterior lobe sometimes distinctly narrower than posterior lobe ( Fig. 2 G). M. pacificus resembles M. major by having a similar body size. However, it can be easily distinguished by the darker coloration and the scutellum devoid of pale stripes laterally ( Fig. 2 G).

Redescription. Female. COLORATION ( Fig. 2 G). Dorsal surface varying from dark reddish to castaneous. Head. Uniformly dark red, sometimes tinged with yellow and pale red, always with yellowish longitudinal stripe along incision in medially of vertex; antenna dark; antennal segment I yellowish, darker, reddish apically; segment II brownish, darker apically; antennal segment III dark brownish; segment IV brownish; rostrum pale, yellowish with darker, reddish or brownish areas; labial segment I varying from entirely yellow to dark brown. Thorax. Pronotum. Usually uniformly castaneous with slightly paler, yellowish or brownish areas; anterior lobe often slightly darker than posterior lobe, with small yellowish or reddish tinge contiguous to medial portion of collar; posterior margin with narrow, pale stripe along its length. Mesoscutum and scutellum. Usually uniformly dark castaneous, paler, reddish laterally. Hemelytron. Ranging from reddish to dark castaneous, with yellowish, transverse stripe beneath base; cuneus varying from reddish to brown, inner angle pale, yellowish; membrane gray, veins darkened, brown. Thoracic pleura. Proepimeron dark brown, metepisternum usually dark brown, sometimes paler dorsally; evaporative areas reddish. Legs. Brown, with contrastingly pale, yellow coxa. Abdomen. Dark brown. STRUCTURE AND VESTITURE ( Fig. 2 G, 5G, H). Head. Rostrum distinctly surpassing abdomen medially, sometimes reaching apex of abdomen. Pronotum. With distinct incision in medially continuous with longitudinal sulcus on posterior lobe; anterior lobe distinctly narrowed; pronotal calli shining, only slightly raised; posterior lobe rugose. Hemelytron. Impunctate, with rugose areas.

Male. According to Carvalho (1956) similar to female. Parameres as pictured in Carvalho (1956, Figs 46c–e).

Measurements. Ψ: body length 3.4–3.9, width 1.4–1.73; Head. Length 0.58, width 0.7–0.84, diameter of eye in dorsal view 0.17–0.22. Antenna. Length of segment I 0.4–0.63, II 0.9–1.21, III 1.2–1.28, IV 1.2–1.58.

Labium. Length of segment I 0.55–0.66, II 0.63, III 0.71, IV 0.38. Pronotum. Length 0.5–0.7, width of anterior margin 0.64, length of lateral margin, 0.64–0.66, width of posterior margin 1.0–1.32.

Biology. Unknown.

Distribution. Indonesia (Sulawesi: Dumoga-Bone National Park), the Caroline Is. ( Palau), Papua New Guinea.
