Yasunaga, Tomohide, 2024, Reassessment of characters of the ‘ Orientomiris-group’, with descriptions of three new genera and eight new species of the tribe Mirini from the Oriental Region (Hemiptera: Heteroptera: Miridae), Acta Entomologica Musei Nationalis Pragae 64 (2), pp. 397-426 : 406

Muttiocapsus teradai sp. nov.

( Figs 3–4 , 10−11 , 80, 112–120)

Type material. HOLOTYPE: ♀, INDONESIA: North Sumatra, Prapat (Parapat), 2°39’N 98°56’E, UV lighting, x.1989, local collector ( AMNH _ PBI 00378799 ) ( ZRC).

Diagnosis. Distinguished readily from the other congener, M. cruciger sp. nov., by its darkened apical 1/5 of antennomere I; longer labium reaching apex of mesocoxa; dark basal half of clavus; broader dark macula on corium; and entirely dark brown metafemur without pale base.

Description. Female (holotype).As in generic description. Head dark brown, weakly shining, glabrous. Antenna pale brown; segment I longer than head width across eyes, with smoky brown apical 1/5; apical 2/3 of segment II smoky brown; segments III and IV missing. Labium shiny dark brown, reaching but not exceeding apex of mesocoxa; segment III brown. Pronotum fuscous, weakly shining, with creamy yellow posterior margin; thoracic pleura shiny dark brown, with posterior half of scent efferent system creamy yellow; mesoscutum and scutellum fuscous. Hemelytra pale brown, with dark brown, X-shaped macula (broader than M. cruciger sp. nov., as in Figs 1A, C ) across corium and cuneus; clavus with darkened anterior half and lateral margin; apex of cuneus pale brown; membrane pale grayish brown, with darkened areolar cells. All coxae dark brown; legs and trochanters pale brown; metafemur, metatibia and all tarsi dark brown. Abdomen shiny dark brown. Female genitalia ( Figs 2F–G , 14G–I ) as mentioned in generic description.

Male. Unknown.

Measurements. See Table 1.
