Muttiocapsus gen. nov.
Type species: Muttiocapsus cruciger sp. nov., here designated.
Diagnosis. This new genus can be distinguished from other mirines and those included in the Orientomiris- -group by the following characters: almost glabrous dorsum ( Figs 1A View Fig , 13A View Fig ); vertical head with flattened frons and clypeus ( Fig. 13C View Fig ); relatively large eyes; grayish white hemelytra with dark, X-shaped macula posteriad ( Figs 1A, C View Fig ); short labium not exceeding mesocoxa; broadened hypophysis of left paramere ( Fig. 13L View Fig ); reduced, tiny right paramere ( Fig. 2B View Fig ); and developed, wide, mesally overlapped interramal lobes ( Fig. 14H View Fig ).
Description. Body elongate, parallel-sided, rather small- -sized in Orientomiris -group, with total length 6.0– 6.5 mm; basic coloration dark brown to fuscous; dorsal surface rather weakly shining, impunctate, smooth, with sparsely distributed, short, simple setae ( Fig. 13A View Fig ). Head vertical, slightly rounded in front, glabrous, minutely wrinkled or roughened ( Figs 13C View Fig , 14A View Fig ); eyes relatively large; vertex with shallow, longitudinal sulcation mesally ( Fig. 13B View Fig ); frons and clypeus flat. Antenna long, almost linear; segment I about as long as head width across eyes; segment II about as thick as segment I, much longer than metafemur; segment III shorter than basal width of pronotum; segment IV shorter than I. Labium short, reaching procoxa but not exceeding apex of mesocoxa. Thorax. Pronotum fuscous, smooth, impunctate, nearly glabrous, with creamy yellow posterior margin; calli indistinct, not clearly demarcated; mesoscutum fuscous, densely covered with minute, velvety pilosity ( Fig. 13F View Fig ); scutellum uniformly shiny fuscous, somewhat roundly inflated, with shallow wrinkles and serrate lateral margin ( Fig. 13F View Fig ); thoracic pleura dark reddish brown, with yellowish brown scent efferent system. Hemelytron grayish white, somewhat matte, with X-shaped dark macula across posterior half of corium and cuneus ( Figs 1A, C View Fig ), almost glabrous, densely covered with reticular microstructures ( Fig. 13F View Fig ); lateral margin of exocorium (embolium) serrate as in Figs 13D–E View Fig and 14C–D View Fig . Legs long, generally slender; metafemur with field of plectra ( Figs 12C–D View Fig , 13G–H View Fig , 14E View Fig ); tarsi relatively short (Fig. 105); pretarsal structure as in Fig. 106. Male genitalia ( Figs 2A–E View Fig , 6A–C View Fig , 13K–O View Fig ). Pygophore with small, triangular process at base of left paramere ( Fig. 6B View Fig ); parameres small-sized; left paramere C-shaped, with broad, spoon-shaped hypophysis ( Figs 2A View Fig , 6B View Fig , 13K–L View Fig ); right paramere reduced, tiny, much smaller than left paramere, with small hypophysis ( Figs 2B View Fig , 6A View Fig , 13M View Fig ); vesica composed of two membranous lobes ( Fig. 2C View Fig ), with small, apical, serrate sclerite ( Figs 2D–E View Fig ), short spicule in middle ( Figs 2C View Fig , 6C View Fig ) and basal spinulate lobes ( Fig 13K–L View Fig ); secondary gonopore relatively small and rounded. Female genitalia ( Figs 2F–G View Fig , 14G–I View Fig ). Sclerotized rings elongate ovoid, relatively contiguous to each other ( Fig. 2F View Fig ); ovipositor (gonapophysis I) sword-like apical part ( Figs 2G View Fig , 14I View Fig ); posterior wall with developed, uniformly spinulate interramal lobes that overlap each other in middle ( Figs 14G–H View Fig ).
Etymology. From Latin, muttio (= mutter, mumble, murmur) combined with mirid generic name Capsus F., 1803, referring to possession of stridulatory device; masculine.
Biology. Unknown.
Distribution. Indonesia (Sumatra), Malaysia (Perak); this new genus is considered to comprise typical Sundaland elements.
