Metajalysus horvathi: Henry 2002: 189(in part, hosts, distribution)
Holotype.Male. ECUADOR: Loja Prov., Univ. Nac., Lojacampus, 04º2.27’S, 79º12.31’W, ca 1900 m, 15 Feb. 2002, T. J. Henry& P. S. F. Ferreira, ex Lycopersicon esculentum(held in trust at USNM). Paratypes: 1♂, Chinchipe Prov., 26 kmE of Loja, along road to Zamora, 03º58.66’S, 79º05.44’W, 1750 m, 16 Feb. 2002, T. J. Henry& P. S. F. Ferreira( USNM); 20♂♂, 7♀♀, same data as for holotype ( MLP, USNM); 11♂♂, 3♀♀, Loja Prov., 24 kmE of Loja, along rd. to Zamora, 03º58.66’S, 79º5.44’W, ca 1750 m, 16 Feb. 2002, T. J. Henry& P. S. F. Ferreira( USNM).
Etymology.This specific epithet denotes the long, erect setae on the appendages.
Diagnosis. Metajalysus pilosus( Figs. 10–12) is distinguished by the uniformly black head (except for the median and lateral carinae on the frons and vertex), extensively black abdomen, usually with only the ventral areas of segments 5–7 pale (except for a black ventral median line), the long femoral and tibial setae, and the distinct inverted V-shaped process ( Figs. 28–30) on the male genital aperture. This species is most similar to M. horvathi( Figs. 7–9) in having a similarly black head and markings on the abdomen. It differs from M. horvathiin having consistently longer setae on the antennae and legs, a distinct inverted V-shaped process on the genital aperture ( Figs. 28–30), and a more stout down-curving arm on the parameres ( Fig. 31).
Description. Male(n = 5; holotypemeasurements in parentheses): Length 3.23–3.62 mm( 3.30 mm), width 0.80–0.83 mm( 0.82 mm). Head: Length 0.42–0.50 mm( 0.48 mm), width across eyes 0.35–0.37 mm( 0.35 mm), interocular width 0.24–0.26 mm( 0.24 mm). Labium: Length 1.15–1.18 mm( 1.15 mm). Antenna: Scape length 1.70–1.92 mm( 1.85 mm); pedicel, 0.64–0.74 mm( 0.74 mm); basiflagellomere, 1.25–1.41 mm( 1.41 mm); distiflagellomere, 0.51–0.58 mm( 0.51 mm). Pronotum: Median length 0.67–0.70 mm( 0.69 mm), posterior width 0.58–0.61 mm( 0.61 mm). Femoral lengths: Pro- 1.15–1.31 mm( 1.28 mm); meso- 1.31–1.50 mm( 1.47 mm); meta- 1.86–2.08 mm( 2.08 mm). Tibial lengths: Pro- 1.38–1.47 mm( 1.47 mm); meso- 1.66–1.76 mm( 1.76 mm); meta- 2.62–2.88 mm( 2.88 mm). General color yellowish brown, with extensive black areas. Head: Black, except for lateral and median (when present) carinae; each lateral carina with one long seta and middle carina or midline with a row of 3 or 4 setae; eyes and ocelli reddish brown. Labium: Yellowish brown, segment I darker brown except at apex, extending to base of metasternum. Antenna: Scape, pedicel, and basiflagellomere uniformly yellowish brown, distiflagellomere black except for brown apex; scape and pedicel with widely spaced setae two to three times diameter of segments, basiflagellomere with shorter more dense setae subequal to diameter of segment. Pronotum( Fig. 16): Yellowish brown, calli darker brown, anterolateral angle and lateral margin along carina black, carinae yellow to yellowish brown; each side of disc with 3 to 5 long erect setae, point of each posterior tubercle with 2 or 3 setae. Scutellum: Yellowishbrown, raised tubercle yellow. Hemelytron: Translucent; veins brown to dark brown, with a slender to quadrate brown spot on either side of middle; membrane with brown patches between veins. Ventral surface: Thorax shiny black; basal three quarters of abdomen black, apical third to one quarter and genital capsule yellow or pale yellowish white, with evenly scattered, somewhat thickened setae. Ostiolar evaporative area: Uniformly whitish yellow. Legs: Coxa brown to dark brown, with apices paler; femora yellowish brown, with long erect setae subequal to or longer than diameters of segments, tibiae yellowish brown with apices darker brown, with long erect setae 2 or more times the diameter of segments. Male genitalia: Genital capsule ( Figs. 28–30) with middle ventral margin of aperture with an inverted V-shaped process; parameres ( Fig. 31) with smaller hind arm elongate, curved, and directed upward. Female(n = 5): Length 3.56–4.08 mm, width 0.83–1.01 mm. Head: Length 0.48–050 mm, width across eyes 0.38–0.40 mm, interocular width 0.26–0.27 mm. Labium: Length 1.20–1.36 mm. Antenna: Scape length 1.73–2.08 mm; pedicel, 0.61–0.74 mm; basiflagellomere, 1.25–1.47 mm; distiflagellomere, 0.51–0.54 mm. Pronotum: Median length 0.72–0.80 mm, posterior width 0.64–0.72 mm. Femoral lengths: Pro- 1.22–1.44 mm; meso- 1.38–1.66 mm; meta- 1.95–2.43 mm. Tibial lengths: Pro- 1.38–1.66 mm; meso- 1.73–2.05 mm; meta- 2.78–3.42 mm. Similar to male in general color, texture, and vestiture.
