Type material. BRAZIL. Minas Gerais State — Santana do Riacho, Serra do Cipó [19.27616°S / 43.55789°O], 17.IV.1999, (A.L. Melo, J.R.I. Ribeiro): 1 m ( DZRJ 2265 ), holotype GoogleMaps ; 1 f (DZRJ 2265), paratype.
Description. MALE HOLOTYPE. Body length (from apex of head to apex of hemelytra): 17.5; greatest vertex width: 1.85; synthlipsis: 1.4; eye width: 2.1; head length: 1.6; greatest head width: 5.9; pronotum length: 2.3; greatest pronotum width: 6.3; scutellum length: 4.9; scutellum width: 5.4.
Color. Body with general color yellow dorsally ( Fig. 37 View FIGURES 37 – 48 ) and brown ventrally ( Fig. 38 View FIGURES 37 – 48 ). Setae light-brown to dark-brown. Thin setae along lateral margin of connexivum greyish. Two light-brown right triangle-shaped maculae on vertex, in dorsal view, extending to frons. Pronotum with foveate area brown. Hind wings mostly hyaline, with veins yellow to brown ( Fig. 40 View FIGURES 37 – 48 ). All trochanters, mid- and hind femora with dark-brown spots.
External morphology. Head with greatest width about 3.7 times its median length and 3.3 times vertex width; vertex 1.3 times synthlipsis; eye width 1.5 times synthlipsis. Pronotum with median length 1.4 times median length of head; greatest width 2.7 times its median length; posterior margin of pronotum concave medially. Scutellum with greatest width 1.1 times its median length; median length 2.1 times pronotum median length; with rounded superficial punctations ( Fig. 39 View FIGURES 37 – 48 ). Ventral surface of middle femur with short and sparse brown pubescence ( Fig. 41 View FIGURES 37 – 48 ); anteapical pointed protuberance short, rounded with blunt setae at apex ( Fig. 42 View FIGURES 37 – 48 ); lateral margin with 13 peglike setae ( Fig. 43 View FIGURES 37 – 48 ). Hemelytra with nodal furrow short, curved anterad, shorter than the distance between its tip and membranal suture. Metaxyphus with margins convex; apex acute; its surface with two strips of setae ( Fig. 44 View FIGURES 37 – 48 ).
Genitalia. Posterior part of male genital capsule ending in acute angle without process; posterodorsal margin of the genital capsule emarginated. Right paramere with a subquadrate projection anteriorly, forming a straight angle with ventral margin, covered with long fine setae throughout median region ( Fig. 45 View FIGURES 37 – 48 ); posteriorly rounded. Left paramere angled anteriorly, rounded posteriorly, covered with long fine setae near posterior end and dorsal region ( Fig. 46 View FIGURES 37 – 48 ).
FEMALE PARATYPE (n=1). Body length (from apex of head to apex of hemelytra): 16.5; greatest vertex width: 1.8; synthlipsis: 1.1; eye width: 2.2; head length: 1.5; greatest width of head: 5.6; pronotum length: 1.9; greatest pronotum width: 6.0; scutellum length: 4.9; scutellum width: 5.0.
Color. Dorsally, general color similar to male holotype; ventrally lighter than male. Ventral surface of middle femur with brown pubescence ( Fig. 48 View FIGURES 37 – 48 ).
External morphology. Differs from holotype by head greatest width 3.1 times vertex width; vertex 1.6 times synthlipsis; eye width 2.0 times synthlipsis. Pronotum with median length 1.3 times median length of head; greatest width 3.1 times its median length; posterior margin of pronotum almost straight. Scutellum with median length 2.6 times pronotum length. Abdominal sternum VII damaged.
Etymology. Named in honour of Dr. Alan Lane de Melo (Universidade Federal de Minas Gerais, Brazil) for his contributions to the study of Brazilian backswimmer taxonomy.
Taxonomic notes. Enitharoides lanemeloi is similar to E. brasiliensis . The ventral surface of the middle femur of both species is not covered by abundant setae and the anteapical pointed protuberance of the middle femur is not developed. These species are easily differentiated by the shape of parameres and genital capsule. In E. brasiliensis , the right paramere is lightly to not notched near the proximal end, in the left paramere a groove forms along the median region and the posterodorsal margin of the genital capsule is almost straight. In E. lanemeloi , the right paramere is strongly notched, the left paramere lacks a groove along the median region and the posterodorsal margin of the genital capsule is emarginated.
