Nesidiorchestes Kirkaldy View in CoL New tribal assignment

Nesidiorchestes Kirkaldy, 1902: 139 View in CoL (gen. n.); Carvalho, 1958: 21 (cat.); Schuh, 1995: 62 (cat.). Type species: Nesidiorchestes hawaiiensis Kirkaldy, 1902 View in CoL by monotypy.

Diagnosis: Recognized by the small size; the brachypterous hemelytron; the large incrassate hind femur and long hind tibia; the pale yellowish brown ground color with variable reddish brown to brown blotches ( Figs. 1 View FIGURE 1 A, B); the trifurcate vesica with medial and ventral spicules with apically dendritic rami ( Fig. 3 View FIGURE 3 ); the phallotheca with a long, narrow process on the left surface ( Fig. 3 View FIGURE 3 ); and the medially converging, strongly serrate interramal lobes ( Fig. 5 View FIGURE 5 ).

Redescription. Male: Short, small. COLORATION: Dorsal aspect patterned with pale yellowish brown and somewhat variably shaped brown to dark reddish brown areas ( Figs. 1 View FIGURE 1 A, B). SURFACE AND VESTI- TURE: Surface dull, covered with microtrichia; dorsum with mixed vestiture composed of dense, pale and dark sericeous setae depending on surface coloration and relatively sparse, reclining pale and dark simple setae ( Figs. 2 View FIGURE 2 B, G); anterior margin of pronotum and posterior margin and frons with long, dark, bristlelike setae ( Fig. 2 View FIGURE 2 A); antenna with dense, reclining pale setae, segment I with four pale bristlelike setae with length slightly longer than diameter of segment; venter and legs with sparse, moderately long, reclining, pale simple setae; dorsal subapical surface of hind femur with several long, dark, bristlelike setae ( Fig. 2 View FIGURE 2 E); forecoxa with a few long, black bristlelike setae; tibiae with two rows of long, pale spines and two lateral rows of short black setae. STRUCTURE: Head: Transverse, triangular in dorsal view ( Fig. 2 View FIGURE 2 B); clypeus slightly prominent, smooth, not visible in dorsal view ( Figs. 1 View FIGURE 1 A, B, 2A, B); frons broadly convex, extending anteriorly beyond clypeus ( Fig. 2 View FIGURE 2 A); vertex slightly convex, posterior margin not elevated; head projecting below ventral margin of eye by slightly more than height of eye; mandibular plate triangular, flat, maxillary plate elongate, surface of both plates smooth; gena long, smooth; buccula reaching posterior margin of head, length about half that of labial segment I; gula obsolete; anterior margin of eye not emarginate, smoothly continuing curvature of frons laterally, eye ovoid, about half height of head in lateral view, adjacent to anterior margin of pronotum and reaching dorsal margin of head; dorsal margin of antennal insertion level with middle of eye and slightly removed from anterior margin of eye in lateral view ( Fig. 2 View FIGURE 2 A); labrum narrow; labium reaching base of abdomen, labial segments I and II subequal in length, III and IV subequal in length, their combined length equal to length of II; antennal segment I less than width of vertex about 87% and reaching ventral margin of head, greatest in diameter, II approximately twice as long as width of head across eyes; about four times as long as I, diameter of II narrower than I, III three-fifths as long as II, its diameter less than that of II, IV approximately 70% of III. Thorax: Transverse, trapezoidal; minute upturned collar barely visible in dorsal view; pronotum nearly flat, lateral margin rounded; anterior and posterior margins very slightly concave medially; anterolateral and posterolateral angles rounded; calli large but faintly differentiated from disc of pronotum; mesoscutum broadly exposed, but weakly differentiated from scutellum; scutellum forming an equilateral triangle; proepisternum small, narrow, slightly protruding laterally, glabrous; propleuron concave; lateral surface of prothorax with dense microtrichia ( Fig. 2 View FIGURE 2 D); mesothoracic spiracle recessed, without evaporative area ( Fig. 2 View FIGURE 2 D); metathoracic scent-gland efferent system with peritreme located medially on evaporative area, slightly protruding, dorsal margin of evaporative area reaching level with dorsal margin of metacoxa ( Fig. 2 View FIGURE 2 D). Hemelytra: Flat; costal margin gently convex, posterior margin weakly sinuate, posteromedial margin separated; claval suture, cuneus, and membrane absent; greatest width of hemelytra greater than width of pronotum at posterior margin. Legs: Coxae cylindrical, elongate, subequal to one-half length of fore and middle femora, approximately equal to one-third length of hind femur; trochanter subtriangular; fore and middle femora elongate ovoid, gently tapering apically, slightly compressed laterally, hind femur incrassate ( Figs. 1 View FIGURE 1 A, B, 2B, E); tibiae slender, length of hind tibia 48% of fore tibia, 58% of middle tibia, and 20% longer than hind femur; first tarsal segment shortest, second and third subequal in length ( Fig. 2 View FIGURE 2 F); pretarsus as in Fig. 2 View FIGURE 2 C. Abdomen: Stout, about twice as long as genital capsule. Genitalia: Genital capsule relatively large ( Figs. 1 View FIGURE 1 A, 2B, H, 3), broadly conical, caudal margin slightly produced in lateral view ( Fig. 3 View FIGURE 3 ); aperture subcircular, reclined; small, simple process dorsal to left paramere socket, projecting posterodorsally ( Fig. 3 View FIGURE 3 ); proctiger not surpassing apex of genital capsule; subgenital plate U-shaped, not reaching apex of genital segment ( Fig. 3 View FIGURE 3 ); left paramere vaguely L-shaped in lateral view ( Figs. 2 View FIGURE 2 H, 3); right paramere flattened, broadly triangular ( Figs. 2 View FIGURE 2 H, 3); phallotheca well sclerotized, somewhat attenuate distally and curved to right side; left margin of aperture with basally broad, elongate process, with narrow curved apex ( Fig. 3 View FIGURE 3 ); aperture dorsal and turned to right side; vesica with single trifurcate spiculum attached to conjunctiva on dorsal left side of sclerotized region of ductus seminus; dorsalmost lobe of spiculum most robust of three lobes ( Fig. 4 View FIGURE 4 ); medial and ventral lobes more narrow and longer than dorsal lobe, both strongly ramified with many thin, dendritic projections.

Female: Very similar to male in structure, vestiture, and coloration, except for slightly wider vertex. STRUCTURE: Genitalia ( Fig. 5 View FIGURE 5 ): Subgenital plate with length equal to 70% of width, apex curved; base of ovipositor located anterior to longitudinal midpoint of abdomen; posterior wall with interramal sclerite strongly sclerotized, ovoid; interramal lobe densely covered with numerous, relatively long, acute microtrichia; dorsal region of posterior wall with anterior surface microserrate; posteromedial surface of wall with sclerotized medial process adjoining base of ovipositor; dorsal labiate plate with medial region faintly sclerotized, area ventral to rings with numerous microtrichia; posterior margin with a few obvious microtrichia, lateral margins small, infolded; sclerotized rings D-shaped, medial margin of ring straight, parallel to long axis of body; anterior wall of vestibulum asymmetrical, formed by protruding and convoluted posterior margin of ventral labiate plate and right side of gonapophyses 8; left side of gonapophyses 8 not protruding.
