Ferreira Jr.): 1 m ( DZRJ 3523 ), holotype. Serra Caraça GoogleMaps – 1880m / MG – Brasil – XI -961/ Kloss, Lenko, Martins & Silva col.: 1 m ( MZUSP), paratype. Espírito Santo State—Domingos Martins, 4-5.VI.1993, (M.R. Gomes, A.M.P.T.C. Silva): 1 m and 1 f, macropterous ( DZRJ 3522 ), paratypes.
Description. MALE HOLOTYPE. Body length (from apex of head to apex of hemelytra): 16.8; greatest vertex width: 1.7; synthlipsis: 1.2; eye width: 2.1; head length: 1.5; greatest head width: 5.8; pronotum length: 1.9; greatest pronotum width: 6.2; scutellum length: 4.6; scutellum width: 5.0.
Color. Body with general color yellow ( Fig. 49 View FIGURES 49 – 61 ). Setae yellow to grey. Two light-brown right triangle-shaped marks on vertex, in dorsal view. Third rostral segment with a brown line along length; fourth segment entirely brown. Foveate area of pronotum dark-brown; pronotum yellow, hyaline. Scutellum with a brown strip on area covered by pronotum and laterally on punctate area ( Fig. 49 View FIGURES 49 – 61 ). Hemelytra hyaline, pale yellow, with membranal suture dark-brown. Hind wings with brown veins, mixed with hyaline and brown areas ( Fig. 52 View FIGURES 49 – 61 ). Legs yellowish with brown spots distributed throughout lateral margin of all trochanters, and along mesal margin of fore- and middle femur ( Fig. 50 View FIGURES 49 – 61 ). Ventrally abdomen yellow, connexivum tinged with brown.
External morphology. Head with greatest width 3.8 times its median length, and 3.5 times vertex width; vertex width 1.4 times synthlipsis; eye width 1.8 times synthlipsis. Pronotum with median length 1.2 times median length of head; greatest width 3.6 times its median length; posterior margin slightly concave medially. Scutellum slightly wider than long; median length 2.4 times pronotum median length; surface with regular, deep punctations in distributed throughout the entire surface except on basolateral angles, delimited by a brown mark at each side ( Fig. 49 View FIGURES 49 – 61 ). Entire ventral surface of middle femur and half of lateral surface of mesotrochanter with conspicuous and dense patch of long setae ( Figs. 53, 55 View FIGURES 49 – 61 ); anteapical pointed protuberance robust and curved at apical margin with a blunt seta at apex ( Fig. 55 View FIGURES 49 – 61 ); lateral margin with seven peg-like setae ( Fig. 55 View FIGURES 49 – 61 ). Hemelytra with nodal furrow curved anterad, almost straight, shorter than distance between its tip and membranal suture. Metaxyphus triangular, with margins almost straight, with two strips of setae ( Fig. 56 View FIGURES 49 – 61 ).
Genitalia. Posterior part of male genital capsule ending in acute angle without process. Right paramere anteriorly truncate, curved ventrally, forming a right angle with ventral margin; dorsal margin straight; posteriorly rounded; patch of setae centered on median region ( Fig. 57 View FIGURES 49 – 61 ). Left paramere angled anteriorly, dorsally straight, covered with long fine setae along dorsal margin ( Fig. 58 View FIGURES 49 – 61 ).
PARATYPES: MALE (n=2) / FEMALE (n=1). Body length (from apex of head to apex of hemelytra): 15.1– 6.1/ 14.4; greatest vertex width: 1.5–1.7/ 1.6; synthlipsis: 1.0–1.2/ 1.1; eye width: 2.0–2.2/ 1.9; head length: 1.5– 1.6/ 1.4; greatest head width: 5.0–5.5/ 5.0; pronotum length: 1.9–2.0/ 1.5; greatest pronotum width: 5.7–6.0/ 5.5; scutellum length: 4.1–4.9/ 3.8; scutellum width: 4.8–5.2/ 4.6.
Color. Male paratypes yellow to brown. Macula on scutellum over punctations, or laterally positioned. Female, in dorsal view, brown, except head and pronotum ( Fig. 59 View FIGURES 49 – 61 ). Labrum, triangle at base of second rostral segment, line along third rostral segment and fourth segment, dark brown. Scutellum brown with yellow macula laterally. Ventrally mostly brown ( Fig. 60 View FIGURES 49 – 61 ).
External morphology. Head with greatest width 3.1 to 3.7 its median length in males, 3.7 in female; vertex width 1.4 to 1.5 times synthlipsis in males, 1.5 in female. Pronotum with median length 1.2 to 1.3 times median length of head in males, 1.1 in female; greatest width of pronotum 3 times its median length in males, and 3.7 in females. Female scutellum with a few punctures apically. Middle femur setose, with setae shorter than in males. Female abdominal sternum VII rounded ( Fig. 61 View FIGURES 49 – 61 ).
Etymology. The specific epithet, tricomerus , refers to the middle femora conspicuously setose, from Greek, trico = hair and merus = thigh.
Taxonomic notes. Enitharoides tricomerus is similar to E. lucasduquei due to the large number of setae on the middle femur ( Figs. 28 View FIGURES 24 – 36 , 53 View FIGURES 49 – 61 ). Although the setae on E. tricomerus femur are longer and more abundant ( Fig. 53 View FIGURES 49 – 61 ), which facilitates the diagnosis, both species can also be distinguished by the anteapical pointed protuberance of the middle femur with curved margins ( Fig. 54 View FIGURES 49 – 61 ); the margins of the metaxyphus almost straight ( Fig. 56 View FIGURES 49 – 61 ); the right paramere dorsal margin is straight and anteriorly truncate, curved ventrally, forming a right angle with the ventral margin ( Fig. 57 View FIGURES 49 – 61 ). E. lucasduquei has abundant but shorter setae on the middle femur; the anteapical pointed protuberance of the middle femur has straight margins ( Fig. 29 View FIGURES 24 – 36 ); the margins of the metaxyphus are convex, tapering in the apical third to a rounded apex ( Fig. 31 View FIGURES 24 – 36 ); the right paramere dorsal margin is sinuous and anteriorly emarginated dorsal and ventrally, making it somewhat projected ( Fig. 32 View FIGURES 24 – 36 ).
