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 : 404-405

Muttiocapsus cruciger sp. nov.

( Figs 1A–B , 2A− E , 6A–C , 12C , 13A–O )

Type material. HOLOTYPE: J, MALAYSIA: Perak, Bukit Larut [= Maxwell Hill], 1,100 m alt., 4.8624˚N, 100.7999˚E, UV (mercury bulb) light trap, 14.vii.1989, T. Yasunaga ( AMNH _ PBI 00378798 ) ( ZRC).

Diagnosis. Currently known only from the holotype male. Recognized by characters mentioned in the generic diagnosis above and distinguished from the other congener, M. teradai sp. nov., by its uniformly pale antennomere I; narrower reddish fascia on corium ( Fig. 1A ); pale basal 1/3 of metafemur; and almost uniformly reddish brown abdomen ( Fig. 1B ).

Description. Male (holotype). As in generic description. Head velvety fuscous brown, weakly shining, glabrous; vertex narrow, less than quarter as wide as head across eyes. Antenna reddish brown; segment I creamy yellow, shorter than head width across eyes, with slightly dark apex; basal 1/3 of segment II, basal half of segment III and base of segment IV creamy yellow; segment III longer than labium. Labium shiny chocolate brown, reaching but not exceeding base of procoxa. Pronotum fuscous, weakly shining, with creamy yellow posterior margin; thoracic pleura coffee brown, with creamy yellow scent efferent system; mesoscutum and scutellum fuscous. Hemelytra grayish white, with dark brown, X-shaped macula across corium and cuneus ( Fig. 1A ); clavus with dark brown lateral margin and claval commissure; apex of cuneus creamy yellow; membrane pale grayish brown. All coxae shiny chocolate brown; legs and trochanters pale brown; apical 2/3 of metafemur, entire metatibia and all tarsi dark brown; metatarsomere II as long as III ( Fig. 13I ); pretarsal structure as in Fig. 13J . Abdomen shiny castaneous brown. Male genitalia ( Figs 2A–E , 6A–C , 13K–O ) as mentioned in generic description.

Female. Unknown.

Measurements. See Table 1.

Etymology. From Latin, cruciger (= having cross, cross- -career), referring to the dark X-shaped macula on the hemelytra of this new species; noun in apposition.

Biology. A single male specimen was collected using UV (mercury) light trap set in primary tropical rainforest zone. No other information is available.

Distribution. Malaysia (Perak).
