Yamada; 1 Ψ, same locality, 13.v. 2005, light trap, K. Yamada. Distribution. Vietnam, Thailand, Malaysia (Peninsular Malaya). Etymology. From the Latin “ atratus ” (= black, dirty black), referring to the mostly black body color; an adjective. Comments. This new species is closely allied to B. crassicornis in general appearance, but it is separable from the latter by the rostral segment III being blackish brown and pale yellow at apex (Fig. 5) (basally darkened in B. crassicornis, as shown in Fig. 6), all femora being entirely blackish brown (fore and mid femora almost yellowish brown or faintly darkened in B. crassicornis), the paramere being apically modified into a acute projection and swollen portion (Figs. 9, 10) (apically hooked in B. crassicornis, as shown in Figs. 13, 14), the paramere being somewhat thickened near apex in dorsal view (Fig. 9) (not thickened in dorsal view in B. crassicornis, as shown in Fig 13), and the omphalus being erect and shortened (Fig. 12) (more elongate and extending toward anteriorly in B. crassicornis, as shown in Fig. 15). The new species also resembles B. novaecaledoniae from New Caledonia in having similar coloration of antenna and femora, but can be distinguished from it by the clavus being of a blackishbrown tinge (stramineous and apically brownish black in B. novaecaledoniae), the pygophore lacking a parameroid process (with weakly developed parameroid process in B. novaecaledoniae), and the paramere being somewhat thickened apically and medially narrowed in dorsal view (thickened toward apex in B. novaecaledoniae). Biology. The present new species was collected from dead leaf clusters of branches of shaded evergreen forest and dead drooping banana leaves in the Malay Peninsula. A single specimen was attracted to artificial light.Published as part of Yamada, Kazutaka & Hirowatari, Toshiya, 2007, A new Buchananiella Reuter (Hemiptera: Anthocoridae) from Indochina and the Malay Peninsula, with a note on B. crassicornis Carayon, pp. 29-36 in Zootaxa 1398 on pages 30-32, DOI: 10.5281/zenodo.17536

Taiwanocapsus Yasunaga & Yamada & Tsai 2023, n. gen.
No full textTaiwanocapsus n. gen. Diagnosis: Externally most similar to Eocalocoris or Miyamotoa, the present new genus can be distinguished by the following characters: dorsal surface only with uniformly distributed, simple, reclining setae and lacking silvery sericeous setae (Fig. 13A–B); male total length greater than female; labium short, not exceeding posterior margin of mesepisternum; parameres remarkably specialized in form (Figs. 7A–B, 13G–J); sclerotized rings enlarged, contiguous to each other mesally (Figs. 7F, 14H); and reduced, narrow interramal lobe (Figs. 7D, 14G). Description. Male: Body elongate oval, tumid, relatively large-sized; basic coloration dark reddish brown; dorsum weakly shining, faintly punctate, with uniformly distributed, simple, reclining setae, lacking sericeous or silvery vestiture. Head: Vertical, rather short; eyes small, contiguous to pronotal collar; vertex with a shallow, faint median sulcus; clypeus weakly projected. Antenna: Generally short; segment I much shorter than head width across eyes, longer than IV; segment II gradually clavate, shorter than basal width of pronotum; segments III and IV equally filiform. Labium: Relatively slender, short, not exceeding posterior margin of mesepisternum. Thorax: Pronotum comparatively shining, not carinate laterally, sparsely and shallowly punctate, with uniformly distributed, simple, reclining setae; collar about as thick as basal part of antennal segment II; calli not clearly demarcated; scutellum moderately elevated; scent efferent system small, with ear-like peritreme (Fig. 13C–D). Hemelytron: Weakly shining, rather declivous at cuneal fracture, with uniformly distributed, pale, simple setae. Legs: Moderate in length; tibial spines short and sparsely distributed; meta-tarsomere III longer than I or II (Fig. 13E); pretarsal structure as in Fig. 13F; parempodia rhombic, relatively long. Genitalia (Figs. 7A–C, 13G–L): Parameres remarkably modified in shape (Figs. 7A–B, 13G–J); left paramere bifurcate, with apically spinulate basal branch (Fig. 13I); right paramere elongate, J–shaped, much longer than left, with a sharp process at middle (Fig. 7B, 13J); vesica widely membranous, elongate, with a single lobal sclerite that is tapered toward apex and spinulate sclerite on right side of membrane (Fig. 7C); ductus seminis inflated subapically. Female: Similar to male in coloration and structure, but body ovoid, shorter and wider. Genitalia (Figs. 7D–F, 14H–K): Sclerotized rings enlarged, contiguous to each other mesally (Figs. 7F, 14H); posterior wall with widened dorsal structure and narrow interramal lobe (Figs. 7D, 14J–L); interramal lobe with uniformly distributed spinules (Fig. 14L). Etymology. Named for Taiwan, combined with the mirine generic name Capsus Fabricius; gender masculine. Type species. Taiwanocapsus luteocordatus Yasunaga, Yamada & Tsai, new species. Distribution. Currently known only from Taiwan. Discussion. The present new genus is at first sight similar to Eocalocoris or Miyamotoa, as having the similar dorsal color pattern and body shape (cf. Fig. 2A–C). Based on the unique male genitalic structure, however, Taiwanocapsus is assumed to be related to Fangumellus Yasunaga, Oh & Lee, described from Laos (cf. Yasunaga et al. 2016). The former can be distinguished from the latter by the larger size, almost uniformly dark reddish brown dorsum, smooth vertex that is not carinate basally, longer antenna, weakly shining and shallowly punctate pronotum, remarkably bifurcate left paramere, and J-shaped, elongate right paramere with the sharp median process.Published as part of Yasunaga, Tomohide, Yamada, Kazutaka & Tsai, Jing-Fu, 2023, New genera and new species of remarkably large-sized or uniquely-shaped mirine plant bugs from Taiwan (Heteroptera: Miridae: Mirinae), pp. 264-288 in Zootaxa 5278 (2) on pages 275-282, DOI: 10.11646/zootaxa.5278.2.3, http://zenodo.org/record/790611
