Orientomiris shoheii, Yasunaga, 2024

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 : 412-416

Orientomiris shoheii sp. nov.

( Figs 7G–H , 8F , 9D− F , 12H , 19A–F )

Type material. HOLOTYPE: J, TAIWAN: Kaohsiung Hsien, Meishan- - Tinchi , 800–2,300 m alt., 23°17′N 120°52′E, 29.vi.1986, K. Baba ( NMNS) ( AMNH _ PBI 00378805 ).

Diagnosis. This is one of the largest species among known congeners and most similar in size and external features to O. eurytus (Yasunaga, 1988) ( Figs 12I , 17G–I ), from which the present new species can be readily distinguished by even shorter antennae, labium and legs; short antennomere I shorter than head width across eyes; uniformly brown antennomere III; entirely pale pro- and mesofemora; different shape of metafemoral plectra ( Figs 12H , 19D vs. 12I, 19I); and longer pygophoral process at base of left paramere ( Figs 9E , 19F ).

Description. Male (holotype). Body almost uniformly fuscous, parallel-sided, large-sized; dorsal surface weakly shining, with rather sparsely distributed, pale, simple, semierect setae ( Fig. 7G ). Head shiny dark brown; vertex wide, 0.39 times as wide as head across eyes. Antenna brown, shorter than total body length (9.33 mm); segment I shorter than head width across eyes; basal 2/3 of segment II dark brown, with pale brown basal 1/3 and brown base; segment III about as long as basal width of pronotum; base of segment IV creamy yellow. Labium pale brown, exceeding apex of metacoxa and reaching abdominal sternum V; apical half of segment IV darkened. Pronotum including collar pale castaneous brown, darkened posteriorly; pleura orange brown, darkened ventrally; metathoracic scent efferent system creamy yellow on posterior half, relatively narrow and triangular ( Fig. 19B ); mesoscutum and scutellum dark brown. Hemelytron uniformly dark brown; exocorial serration as in Fig. 191; membrane smoky brown. Coxae and legs pale brown; metafemur and basal half of metatibia darkened; metafemoral plectra as in Figs 12H , 19C ; tibial spines dark brown; pretarsal structures as in Fig. 19E . Abdomen dark brown, partly speckled with reddish brown. Male genitalia ( Figs 8F , 9D–F , 19F ): pygophore with long process at base of left paramere ( Figs 9E , 19F ); right paramere short, about as long as hypophysis of left paramere ( Fig. 9D ); vesica with developed membranous lobes, with generally small lobal sclerites as in Figs 8F , 9F .

Female. Unknown.

Measurements. See Table 1.

Etymology. This giant, remarkable new species is named after Shohei Ohtani, a world famous Japanese or Asian- -born baseball slugger (Los Angeles Dodgers, US Major League Baseball), in honor of his conspicuous, miraculous record-breaking performances in recent years; a noun in the genitive case.

Biology. Unknown.

Distribution. Taiwan (Kaohsiung).
