Waterhouseana delicata , new species Plate 7, Figures 42 , 43 A–D

DIAGNOSIS: Recognized by small size, and lack of dark setae on surface of hemelytron posterior to apex of clavus as found in W. illustris .

DESCRIPTION: Male: Macropterous, small, medially constricted. Total length 2.73– 2.77, width pronotum 0.71–0.72, maximum width across hemelytra 0.74. COLORA- TION: Castaneous and dark brown. Head: Castaneous. Eyes silver to dark purple. Labium golden. Antennal segment 1 golden ventrally, dark brown anteriorly, segment 2 brown with lightening on medial M, segment 3 golden proximally and dark distally to completely golden, segment 4 brown. Thorax: Pronotum, scutellum, and thorax castaneous to dark brown. Dorsolateral margin of metepisternum and scent gland continuous in coloration with thoracic pleura. Legs: All coxae pale brown, procoxa sometimes more golden brown. All femora castaneous to brown with ventral surface paler golden, all tibiae basally dark brown to castaneous, distally golden, metatibia with parallel rows of dark spicules and long, obvious golden setae. Basal tarsomeres golden, distally dark brown. Hemelytra: Primarily castaneous to dark brown with anterior of corium castaneous to golden brown, clavus castaneous with medial area darker brown, transparent areas on posterolateral margins of corium adjacent to apex of clavus with dark posterior margin that transverses entirety of hemelytron (pl. 7), white patch along medial margin of corium posterior to clavus and anterior part of hemelytral membrane surrounded with dark brown margin, corial margin golden brown medially, dark brown apically. Anterolateral margin of cuneus white for nearly J total area of cuneus, posterior dark brown. Membrane pale brown with veins lacking pigmentation. Abdomen: Abdominal sternite 1 yellowish with dark posterior margin, second abdominal sternite white to transparent, remaining segments dark brown. SURFACE AND VESTITURE: Dorsal surface, including eyes covered with long, erect pale brown setae. Head, pronotum and scutellum distinctly shiny. Hemelytron punctate also with erect, black, evenly distributed setae. Reflective patches on clavus and cuneus. Gena and gula with long, dense, black setae. STRUC- TURE: Head: Wide, flat, lateral margins including eyes obscuring anterior margin of pronotum in lateral view. Clypeus flush with anterior margin of frons in lateral view, not visible in dorsal view. Vertex convex, posterior margin shelflike, width nearly equal to L width of one eye. Dorsal margin of eyes continuous with vertex, height nearly encompassing total height of head, vertex visible in lateral view. Antennal segment 1 invertedcoke-bottle shaped, surpassing apex of head, segment 2 long and equal to in diameter to antennal segment 1, increasing in diameter distally, length segment 2 nearly1.2 times head width, segments 3 and 4 slender and less than half length of segment 2. Labial segment 1 not quite attaining posterior margin of head, apex of labium surpassing apex of procoxa. Thorax: Pronotum longer than wide with medial constriction forming an hourglass appearance, posterior lobe swollen and appearing strongly convex in lateral view; pronotal collar narrow and flat. Mesoscutum hidden by posterior margin of pronotum, scutellum swollen anteriorly. Scent gland approximately J total area of metepimeron. Legs: Moderate length, slen- der, metafemur widest subapically and appearing kneelike. Claws of moderate length and width, pulvilli less than half of claw length and small. Parempodia parallel and setiform. Hemelytra: Dorsally flat; lateral margin strongly medially constricted, swollen anterior to cuneal fracture forming lobelike process. Cuneus triangular, lateral margin cweakly swollen in area occupied by white pigmentation, mesial margin weakly convex, total length greater than M total length of hemelytral membrane, cuneal fracture angled anteromesially. Abdomen: Narrow anteriorly, widening posteriorly, petiolate. Abdominal sternite 1 longer than wide. GENITALIA (fig. 43): Pygophore: Small, with spinelike process on dorsalposterior margin, occupying about one-fifth length of abdomen, ventral margin weakly sloping upward toward apex. Endosoma: Minute, slender, twisted, S-shaped. Secondary gonopore small, horse-collar shaped, located at apex of endosoma (fig. 43A). Phallotheca: Small, L-shaped, apex gently tapering toward a point and directed ventrally (fig. 43D). Right Paramere: Small, elongate, and parallel sided, nearly equal in size with left paramere, apex rounded (fig. 43B). Left Paramere: Small; posterior process slender and strongly curving ventrally, with sensory pits, relatively elongate compared to anterior process; anterior

process stout, dorsal surface nearly reaching to dorsal margin of posterior process; dorsomedial margin convex (fig. 43C).

Female: Unknown.

ETYMOLOGY: Named for its delicate, small size.
