Diagnosis. This species can be recognized by the body length (1.20 – 1.50 mm) and patches of silvery setae on male abdominal mediotergites II and V–VII, and on laterotergites I and IV–VI ( Fig. 3a View Figure 3 ). Fore femur yellow, brownish at apex; row of long brown setae on distal half of posterior surface ( Fig. 3b View Figure 3 ). Paramere curved, long and narrow ( Fig. 3d View Figure 3 ); dorsal vesical sclerite Y-shaped, elongated, broader and bifurcated at apex ( Fig. 3c View Figure 3 ).
Description. Apterous male ( Fig. 3 View Figure 3 ). Body robust, densely covered with setae on dorsum, these longer on abdominal medio- and laterotergites. General color grayish black. Head velvety; dark brown, with basal transverse stripe dark orange brown reaching mesal margins of eyes; impressed longitudinal midline shining; a pair of oblique indentations posteriorly. Antenniferous tubercles swollen, shining brown.Antennomeres I–III yellow to yellowish brown; IV darker brown. Antenna covered by sparse short brownish setae; three long, thicker black setae on antennomeres II–III; antennomeres I–III subcylindrical; I–II slightly thicker than III; IV fusiform, with acute apex, at middle thicker than I–III. Buccula shining brown to dark brown. Article I of labium shining black with lateral brown marks; II–III shining brown; IV shining dark brown to black.
Sides of thorax and abdomen with several long, curved, black setae ( Fig. 3a View Figure 3 ). Thorax punctate dorsally, laterally, and ventrally. Pronotum grayish black, covering remainder of thorax centrally; anterior lobe with two dark orange rounded spots behind head; posterior lobe lighter on longitudinal midline, with a pair of sublateral patches of silvery setae ( Fig. 3a View Figure 3 ). Legs unarmed, without distinct tufts of setae. Fore coxa dark brown; mid coxa brown, darker towards apex; hind coxa brown. Fore trochanter yellow with brown proximal tip; middle and hind trochanters yellowish brown at base, brown at apex. Fore femur yellow, brownish at apex; row of long brown setae on distal half of posterior surface ( Fig.3b View Figure 3 ). Middle and hind femora yellow with a brown mark before middle and brown apex.Fore tibia yellow on proximal 2/3, lighter ventrally; distal 1/3 yellowish brown; wider towards apex; several long black setae on anterior surface; black grasping comb measuring 1/3 of tibial length, surpassing its apex; ventral surface with a weak concavity measuring 1/2 of tibial length.Middle and hind tibia annulate, yellow with brown to dark brown rings proximally, centrally, and distally. Fore tarsus oval, approximately twice as long as wide; proximal half yellowish, apex brownish; claws falcate, measuring 1/3 of tarsal length. Middle tarsus yellowish brown up to base of article II, then brown to dark brown; deeply cleft, with four leaf-like structures inserted on proximal 1/3. Hind tarsus brown; claws falcate, subequal in length to tarsomere I.
Abdomen grayish, with patches of silvery setae laterally on mediotergites II and V–VII, and on laterotergites I and IV–VI ( Fig. 3a View Figure 3 ); mediotergites slightly longer than II–VI; II–VI subequal in length; VII longer than VI; exposed portion of VIII short. Laterotergites slightly raised. Sterna V–VII with longitudinal black stripe at midline. Paramere curved, long and narrow ( Fig. 3d View Figure 3 ); dorsal vesical sclerite Y-shaped, elongated, broader and bifurcated at apex ( Fig. 3c View Figure 3 ).

Comments. Euvelia meta was first described based on a female specimen from Meta Department, Colombia, without any further records ( Molano et al., 2016). It is herein recorded for the first time from Amazonas and Vichada departments ( Fig. 4 View Figure 4 ). This species can be recognized by the body length of 1.20–1.50 mm, maximum width of the female 0.90 mm, and patches of silvery setae on abdominal mediotergites II and V–VII (male) or II–III and V–VII (female), and on laterotergites I and IV–VI. The most similar congener is E. discala Polhemus & Polhemus, 1984, in which the female maximum width is 1.19 mm and patches of silvery setae occur on abdominal mediotergites II and VI–VII, and on laterotergites I and IV.
