( Figs. 2 View FIGURE 1 – 4 , 5–7 View FIGURE 5 – 10 , 11 View FIGURE 11, 12 , 13–16 View FIGURE 13 – 20 )
Diagnosis. Recognized by the following characters: Body ( Fig. 2 View FIGURE 1 – 4 ) much slenderer than congeners. Antennal segment III ( Figs. 2 View FIGURE 1 – 4 , 6, 7 View FIGURE 5 – 10 ) black except for pale yellow base and apex. Hemelytra ( Fig. 2 View FIGURE 1 – 4 ) black to brownish black except for off–white on outer half of clavi, almost all of embolium, and part along embolial suture in corium; membrane semi–transparent, centrally with blackish stripes. Pygophore ( Fig. 13 View FIGURE 13 – 20 ) turbinate; flagellum ( Figs. 13–15 View FIGURE 13 – 20 ) basally bifurcate, nearly straight. Copulatory tube ( Fig. 16 View FIGURE 13 – 20 ) noticeably elongate, bulbous at apical 1/3.
Description. Coloration. Body ( Fig. 2 View FIGURE 1 – 4 ) generally black, shiny on dorsal and ventral surfaces. Head, thorax, and abdomen uniformly black. Eyes and ocelli reddish black. Antennae ( Figs. 2 View FIGURE 1 – 4 , 6, 7 View FIGURE 5 – 10 ) black to brownish black except for pale yellow base and apex of segment III in male, entirely pale yellow segment III in female; segment IV apically tinged with reddish black. Rostrum uniformly black. Hemelytra ( Fig. 2 View FIGURE 1 – 4 ) black to brownish black except for off–white on outer half of clavi, almost of embolium, and part along embolial suture in corium; membrane semi–transparent, medially with blackish stripe. Legs generally black; fore tibia pale yellow except for black at base; mid– and hind tibiae mostly black; tarsi pale yellow, gradually darkened toward apex.
Structure. Body ( Fig. 2 View FIGURE 1 – 4 ) elongate, much slenderer than the other congeners. Head ( Figs. 2 View FIGURE 1 – 4 , 5 View FIGURE 5 – 10 ) elliptical, smooth on dorsal surface, about 1.2 times as long as head width across eyes, sparsely clothed with silky, short, recumbent setae; pairs of long, erect setae laterally on tylus, on anterior part of inner margin of eye, and between eye and ocellus; ante-ocular region about 1.2 times as long as length of eye in dorsal view; vertex about 2.0 times as wide as eye in dorsal view; postocular portion distinctly long, not constricted; eyes with short setae; ocelli small. Antennae ( Figs. 6, 7 View FIGURE 5 – 10 ) densely clothed with short recumbent and long suberect setae; long suberect setae slightly longer than or as long as width of segment; segment I almost reaching apex of head, sparsely clothed with short setae; segment II cylindrical in male, slightly thickened toward apex, as long as head width across eyes; segment III approximately 0.57 times as long as segment II; segment IV weakly flattened, approximately 1.4 times as long as segment III. Rostrum stout, not reaching fore coxae, sparsely clothed with silky, short, erect setae; segment II thicker than the other segments; segment III about 4.0 times as long as segment II; segment IV about 0.6 times as long as segment III.
Pronotum ( Figs. 2 View FIGURE 1 – 4 , 5 View FIGURE 5 – 10 ) trapezoidal, highly polished, impunctate, sparsely distributed with silky, short, recumbent setae, bearing four distinct corner setae and a pair of long erect setae at anterior angle of callus; anterior margin nearly straight, slightly longer than mesal length; lateral margin weakly curved and strongly carinate at anterior 2/3; posterior margin shallowly concave, approximately 2.2 times as wide as anterior margin; collar long, weakly rugose, with sparse, silky, short setae; posterior half of pronotum weakly depressed, with transverse rugae. Scutellum ( Fig. 2 View FIGURE 1 – 4 ) levigate, extremely swollen on anterior half and depressed on posterior half, with a pair of long, erect setae on basal 1/4 of lateral margin. Hemelytra ( Fig. 2 View FIGURE 1 – 4 ) narrowed toward apex, impunctate, with poorly distributed, silky, short, recumbent setae; apical part of corium approximately 2.5 times as wide as that of embolium; cuneal margin about 0.75 times as long as embolial margin; cuneus with short setae at apex. Ostiolar peritreme ( Fig. 11 View FIGURE 11, 12 ) accompanied with narrow, smooth, shining area anterior to gutter and broad alutaceous area posterior to gutter; outer margin of ostiolar peritreme posterolaterally a little raised above level of surrounding evaporative area; smooth shining area slightly broader than that of M. bellatula ; evaporative area subtriangular. Legs densely covered with yellow, recumbent setae; fore tibia slightly thickened toward apex, furnished with a row of 18–20 short teeth along entire ventral surface in male; hind tibiae weakly depressed; hind coxae separated. Abdomen clothed with rows of short setae on ventral surface of each segments; seventh and eighth sterna laterally with pairs of long, suberect setae; scissure on abdominal tergite reaching end of posterior margin of third segment.
Male genitalia ( Figs. 13–15 View FIGURE 13 – 20 ): Pygophore ( Fig. 13 View FIGURE 13 – 20 ) turbinate, posteroventrally covered with 8–10 long and stout setae; paramere ( Figs. 14, 15 View FIGURE 13 – 20 ) broadened in general shape; cone ( Figs. 14, 15 View FIGURE 13 – 20 ) wide, acute at apex in dorsal view, abruptly elevated at apex in lateral view; flagellum ( Figs. 14, 15 View FIGURE 13 – 20 ) basally bifurcate, long, nearly straight, tapering, approximately 1.5 times as long as width of cone.
Female genitalia ( Fig. 16 View FIGURE 13 – 20 ): Copulatory tube ( Fig. 16 View FIGURE 13 – 20 ) mesally located at sternum VII, very close to base of ovipositor, elongate, accompanied by strongly sclerotized basal part leading into membranous and blossom– like apex; strongly sclerotized basal part bulbous at anterior 1/3.

Distribution. Indonesia (Bali Island).
Etymology. The species epithet, a noun in the genitive, is dedicated to Dr. Tadashi Ishikawa, who collected the type specimens of this new species.
Remarks. This new species is most similar in general aspect to M. moraguesi , from which it can be distinguished easily by the male antennal segment III being black to brownish black except for pale yellow base and apex ( Fig. 6 View FIGURE 5 – 10 ) (in M. moraguesi , uniformly pale yellow); the rostrum being uniformly black (vs. segment III pale yellow); the corium being black to brownish black except for off–white along embolial suture ( Fig. 2 View FIGURE 1 – 4 ) (vs. mostly clear); cone being wide ( Fig. 14 View FIGURE 13 – 20 ) (vs. much narrower); and the flagellum being basally bifurcate and nearly straight ( Figs. 14, 15 View FIGURE 13 – 20 ) (vs. not bifurcated and roundly curved). This new species also resembles M. sawtellense in having similar coloration of male antennal segment III and a basally bifurcated flagellum. However, M. ishikawai is readily separable from M. sawtellense by the male fore tibiae being furnished with a row of 18–20 short teeth on whole of ventral surface (in M. sawtellense , 15–16 long teeth); the femora without teeth (vs. 5–7 long teeth); the flagellum being nearly straight ( Fig. 14 View FIGURE 13 – 20 ) (vs. slightly curved); and the copulatory tube being elongate and bulbous at anterior 1/3 of sclerotized basal part ( Fig. 16 View FIGURE 13 – 20 ) (vs. weakly sclerotized cylinder merging into longer, slightly convoluted tubule).
