Diagnosis.

This species is readily distinguished from all other species of Tytthus by the dark brown to fuscous head, pronotum, and scutellum; pale translucent hemelytra; pale yellow legs; and especially the pale first antennal segment having a broad, dark band through the middle. No other species has a broad band on antennal segment I with the base and apex pale. Males and females of this species are always macropterous.

As noted in the diagnosis of Tytthus juturnaiba , a photograph of the holotype stored in the PBI Heteroptera Species Database contradicts the color of antennal segments I and II described in the original description. If my interpretation of the banded antennal segment I in the photograph is correct, the two species probably are conspecific. A final decision, however, must await examination of the holotype of Tytthus juturnaiba .

Description.

Male (n = 10) (26, 63, 64): Length to apex of hemelytron 2.40-2.60 mm, length to base of cuneus 1.68-1.80 mm, width across hemelytra 0.82-0.83 mm. Head: Length 0.27-0.29 mm, width across eyes 0.54-0.59 mm, interocular width 0.27-0.29 mm. Labium: Length 0.94-1.07 mm. Antenna: Segment I length 0.24-0.29 mm, II 0.75-0.96 mm, III 0.37-0.51 mm, IV 0.32-0.34 mm. Pronotum: Length 0.32-0.34 mm, basal width 0.74-0.77 mm.

Coloration: Head (Figs 65-67: Uniformly black, with an indistinct, pale yellow, interocular spot near inner margin of each eye; eyes reddish brown. Labium: Pale yellow, with apical half of segment IV brown. Antenna: Segment I pale or whitish on apical and basal fourth, with a broad, uniformly dark brown to fuscous band through middle and a very narrow dark brown ring at base; segments II–IV uniformly dark brown to fuscous. Pronotum: Uniformly dark brown to fuscous. Mesoscutum: Uniformly dark brown to fuscous. Scutellum: Uniformly dark brown to fuscous. Hemelytron: Translucent, highlighted or tinged with pale brown on clavus and inner half of corium, inner half of clavus along claval commissure accented with darker brown; translucent dusky brown. Ostiolar evaporative area (Fig. 68): Dark reddish brown. Ventral surface: Thorax and abdomen uniformly dark reddish brown to fuscous. Legs: Coxae pale yellow, with bases reddish brown; femora pale yellowish, with metafemur sometimes accented with pale orange; tibiae, tarsi, and claws (Fig. 70) pale yellow.

Structure, texture, and vestiture: Head: Shiny, impunctate, wider than long; buccula narrow, tapering posteriorly, ending near hind margin of eye; set with scattered, relatively long, semierect setae. Labium: Extending just beyond metacoxae to base of abdomen; segment I extending past base of head to middle of xyphyus before procoxae. Antenna: Segment I with short, relatively sparse, recumbent setae and two or three erect, subapical, bristlelike setae; segment II evenly set with short, recumbent setae. Pronotum: Shiny, impunctate; calli weakly swollen, entire area covered with a glaucous sheen; anterior angles rounded; lateral margins concave, strongly flaring at posterior angles; posterior margin weakly sinuate; evenly set with recumbent and semierect setae, especially on disc. Mesoscutum: Broadly exposed; set with scattered semierect setae. Scutellum: Impunctate, equilateral; set with scattered, relatively long, semierect setae. Hemelytron: Macropterous, cuneus and membrane fully developed, extending well beyond apex of abdomen; evenly set with recumbent setae.

Male genitalia (Fig. 69): Left paramere (Fig. 156): Mitt-shaped; right arm long and broad, tapering to a point apically; left arm shorter, pointed. Right paramere (Fig. 157): Elongate oval. Endosoma (Fig. 158): Strongly C-shaped. Phallotheca (Fig. 159): Relatively slender, apically acute.

Female (n = 10) (Fig. 27): Length to apex of hemelytron 2.66-3.01 mm, length to base of cuneus 2.02-2.18 mm, width across hemelytra 0.96-1.04 mm. Head: Length 0.29-0.32 mm, width across eyes 0.56-0.61 mm, interocular width 0.27-0.32 mm. Labium: Length 1.06-1.17 mm. Antenna: Segment I length 0.26-0.27 mm, II 0.70-0.86 mm, III 0.45-0.54 mm, IV 0.43-0.45 mm. Pronotum: Length 0.32-0.35 mm, basal width 0.80-0.86 mm.

Similar to males in overall appearance, differing primarily in the slightly broader body form.

Hosts.

No specific host known. Associated with grass savannas and marshes and pine-oak sand scrub.

Distribution.
