Euvelia mazzucconiae sp. nov.

( Figs. 1–6 )

Diagnosis. Large species, with length greater than 2.7 mm; antennomere IV slightly curved, with acute apex; male fore femur with a tuft of brown setae on anteroventral third ( Fig. 6 ); female pronotum with longitudinal shining area, subequal in width to antennomere I ( Fig. 4 ).

Apterous male ( Figs. 2–3 , 6 ). Body elongated; length 2.76; width on prothorax 1.23. General color grayish black.

Head black, with basal transversal stripe slightly lighter; antennomeres covered by sparse short brownish setae; proximal 1/3 of antennomere II with three long black setae, with about half the length of I; base of antennomeres I and II yellowish, III, IV and apex of II brownish; length of antenomeres I–IV 0.32-0.34-0.44-0.37; antennomeres I- III cylindrical, IV slightly curved, with acute apex. Articles I–III of rostrum yellowish, IV brown; length of articles I–IV 0.15-0.1-0.25-0.15.

Pronotum grayish black, width/length ratio = 1.6, completely covering the mesonotum; anterior lobe with yellowish transversal macula centraly behind head; anterolateral angle of anterior lobe with long brownish setae, remaining areas with short golden setae; pronotum, pro-, meso-, and metasternum punctate.

Legs yellowish ventrally, dorsally brownish and covered by golden setae. Coxae and trochanters yellowish, middle trochanter longer than others; proximal half of middle femur yellow, rest brownish, anteroventral 1/3 with a tuft of brownish setae ( Fig. 6 ); middle and hind femora dorsally yellowish on base then brown, ventrally yellowish, middle femur with slightly darker stripe on inner surface. Fore tibia with proximal 2/3 brown, distal 1/3 light brown, proximal 1/3 of middle tibia slightly darker. Fore tarsus oval, approximately twice as long as wide, proximal half yellowish, apex brownish, claws curved, measuring 1/3 of tarsal length. Middle and hind tarsus brown, length of middle tarsomere I subequal to II, which has four leaf-like structures inserted on proximal 1/3; hind tarsomere II twice as long as I, with claws subequal in length to tarsomere I.

Abdomen grayish, tergite I longer than II; III–V subequal in length; VI–VII subequal, longer than previous tergites. Tergite II with dull areas on sides, VII and apex of connexives yellowish; abdominal sternites II–VI with longitudinal black stripe. Genitalia yellowish.

Proportions of legs: fore femur/ tibia/ tarsomere I = 0.8-0.7-0.46; middle femur/ tibia/ tarsomere I/ tarsomere II = 1.56-1.34-0.5-0.6; hind femur/ tibia/ tarsomere I/ tarsomere II =1.06-0.98-0.15-0.35.

Apterous female ( Figs. 4–5 ). Body length 3.0, width on prothorax 1.41. Similar to the apterous male, except for the pronotum with a shining glabrous longitudinal stripe subequal in width to antennomere I ( Fig. 4 ); fore femur without tuft of brownish setae on anteroventral 1/3; outer portion of abdominal tergites and inner portion of connexives with dull areas; and outer margin of connexives with long seate. Genitalia dark.

Proportions of legs: fore femur/ tibia/ tarsomere I/ tarsomere II = 0.8-0.7-0.38; middle femur/ tibia/ tarsomere I/ tarsomere II = 1.54-1.40-0.5-0.6; hind femur/ tibia/ tarsomere I/ tarsomere II = 1.04-0.96-0.15-0.35.

Material examined. HOLOTYPE (♂) ( ICN): ‘ Colombia, Antioquia Mpio: Necoclí, Mar Caribe en el Golfo de Urubá, Ciénaga La Marimonda. 7/IX/95. Col: Hernán Aristizábal-Garcia. 297 ejemplares.’. PARATYPES (40 ♂, 40 ♀) ( ICN) same data as holotype; PARATYPES (50 ♂, 50 ♀) (EQ) same data as holotype.

Etymology. This species is named in honor of Dra. Silvia A. Mazzucconi, in recognition of her important contributions to the systematics of Neotropical aquatic Heteroptera .
