( Figs. 1 , 2–7 , 35, 36 , 82–84 )

Diagnosis. Cyrtocapsus lazelli ( Figs. 1 , 35, 36 ) is recognized by black dorsum, with the clypeus, underside of the head, antennae, legs (including the coxae), the apical third of the cuneus, the ovipositor, and last segment of the female abdomen white.

It is similar to several other black species with pale antennae and legs, such as C. elutipes ( Figs. 20–22 ) and C. rostratus ( Figs. 49–51 ) but is readily distinguished by the white undersurface of the head and apical third of the cuneus, the latter of which is unique in the genus.

Description. Male ( Fig. 35 ) (n = 5; plus holotype measurements in parentheses): Length to apex of membrane 2.82–3.23 mm (3.10 mm), length to base of cuneus 1.82–2.14 mm (2.02 mm), widest width across hemelytra 1.23– 1.46 mm (1.23 mm). Head: Width 0.70–0.74 mm (0.70 mm), interocular width 0.38–0.40 mm (0.40 mm). Labium: Length 0.86–0.96 mm (0.91 mm). Antenna: Segment I length 0.35–0.38 mm (0.35 mm); II, 0.42–0.43 mm (0.38 mm); IV, 0.26–0.32 mm (0.30 mm). Pronotum: Median length 0.61–0.69 mm (0.61 mm), basal width 1.04–1.15 mm (1.02 mm).

Coloration: Head with vertex and frons black, including inner margins of eyes; clypeus and underside pale yellowish white to white. Labium pale yellowish white to white, apex of segment IV pale brown. Antenna pale yellowish white to white. Pronotum and scutellum black. Hemelytron black, cuneus black with apical third white; membrane white, veins white distally, inside of areole and part of vein level with dark area of cuneus black. Ventral surface black; female ovipositor and surrounding segments usually pale yellowish white. Legs uniformly pale yellowish white to white, claws pale brown.

Texture and vestiture: Head weakly shiny, rugose, frons transversely striate, with relatively fine, silvery, sericeous setae at base, along median and inner margins of eyes, and across striations. Labium long, extending nearly to bases on hind coxae. Pronotum dull, densely and finely punctate, punctures on calli and collar finer and more sparse, with relatively slender, silvery sericeous setae, setae on disc shorter and finer. Scutellum uniformly black. Hemelytron dull, impunctate, with scattered, fine, short, silvery, sericeous setae.

Male genitalia: Left paramere ( Fig. 82 ) somewhat C-shaped, with a slender stem, an elongate main body, and narrowed, curving apex. Endosoma ( Fig. 83 ) as in generic description. Right paramere ( Fig. 84 ) L-shaped with a slender basal stem and an elongate tapering main body.

Female ( Fig. 36 ) (n = 5): Length to apex of membrane 2.74–3.10 mm, length to base of cuneus 1.82–1.98 mm, widest width across hemelytra 1.23–1.38 mm. Head: Width 0.67–0.74 mm, interocular width 0.38–0.40 mm. Labium: Length 0.80–0.94 mm. Antenna: Segment I length 0.32–0.40 mm; II, 0.40–0.42 mm; III, 0.24–0.27 mm; IV, 0.27–0.35 mm. Pronotum: Median length 0.59–0.67 mm, basal width 1.01–1.12 mm.

Etymology. I am pleased to name this new species after Dr. James ‘Skip’ Lazell, who kindly supported my fieldwork to Guana Island in 2007, 2008, 2009, and 2012, and who has been the leader in studying the biodiversity and promoting the conservation of the flora and fauna of this small British Virgin Island ( Lazell 2005).

Host. Solanum polygamum Vahl [ Solanaceae ]. Adults and nymphs were abundant in all areas of Guana Island where S. polygamum grew, causing extensive foliar chlorosis.

Distribution. Cooper Island and Guana Island, British Virgin Islands, Puerto Rico, and St. Thomas, U.S. Virgin Islands.

Type material. Holotype ♂: BRITISH VIRGIN ISLANDS: Guana Island : North Beach at maintenance and supply area, 18º 28.815’N, 64º24.521’W, 17 Oct. 2009, T.J. Henry & A.G.
