(Figures 1 to 12, 26 and 27)
Diagnosis. The male imago of Atopophlebia pacis, sp. nov., can be distinguished from the other species of the genus by the following combination of characteristics: 1) Eyes meeting on meson of head; 2) Fore wings hyaline, veins yellow (Fig. 2); 3) Fore tibia completely tinged with black; 4) Abdominal segments yellowish, terga VIII with conspicuous triangular anterolateral black mark (Fig. 1); 5) Apical projection of penis lobe short (Fig. 4). The nymph can be distinguished from the other species of the genus by the following combination of characteristics: 1) Labial palp segment I strongly widened, 0.7 times as wide as long (Fig. 10); 2) Abdominal color pattern as in male imago (Fig. 5).
Description of male imago (in alcohol). Lengths: body: 7.25 mm; fore wings: 7.6 mm; hind wings: 1.0 mm.
General coloration: yellowish.
Head: Eyes meeting on meson of head. Head yellowish orange. Lateral ocellus surrounded with black. Upper portion of turbinate eyes orange, lower portion dark grey.
Thorax: General color yellowish with three black lines in the pronotum mid-part; pleural sclerites washed with dark grey. Forewing (Fig. 2): maximum width 0.4 times maximum length; membrane hyaline, veins yellow; vein MP2 attached at base to MP1; IMP attached at base to veins MP1 and MP2. Hind wing (Fig. 2) base pigmented with gray; costal projection located on apical 0.65, apex of wing roundly acute; 3 cross veins present. Fore femur orange; fore tibia completely tinged with black. Middle and hind legs orange; middle and hind tibiae washed with brown. Patella-tibial suture absent on all legs.
Abdomen: yellowish with intersegmental membrane between segments I to VIII tinged with diffuse black; terga I with lateral margin tinged with diffuse black, terga VIII with black anterolateral triangular mark and anteromedial black spot (Fig. 1). Abdominal sterna pale yellowish; subgenital plate and forceps yellow (Figs. 3 and 4). Penes fused in basal 1/3 with lobes 0.3 times as wide as long; each lobe with an apical short projection directed ventro-laterally (Figs. 3 and 4). Cerci and terminal filaments brownish tan.
Description of nymph (immature). Head: yellowish brown, vertex diffusely tinged with black; area anterior to median ocellus yellow, triangular (Fig. 5). Labrum (Fig. 6) with lateral margins slightly angled, distal margin with broad and flat denticles, except for the median denticle, which is narrower and rounded apically (Fig. 7). Mandible (Fig. 8) diffusely tinged with black on exposed dorsal surface. Maxilla (Fig. 9) with outer margin of stipe tinged with black. Hypopharynx with apex of superlingua strongly curved. Labium (Fig. 10): labial palp segment I strongly widened, 0.7 times as wide as long.
Thorax: yellowish brown with black marks on anterior and lateral margins of mesonotum (Fig. 5). Legs (Figs. 11 and 12) yellowish white; fore femur with subapical pale brown mark; mid femur missing; hind femur almost completely pigmented by pale brown. Foreleg (Fig. 11): femur with outer margin with row of long and fine setae along distal ¾ and row of spatulate setae, little shorter than fine setae, on distal ½; anterior surface with few short blunt setae on distal ½. Hind leg (Fig. 12): femur with few fine setae on outer margin, spatulate setae present from base to apex; anterior surface with short blunt setae more numerous and more spread than in foreleg; tibia with few spatulate setae on outer margin. Tarsal claws with a row of 5–8 denticles, the apical denticle larger than the others.
Abdomen: yellowish brown with black markings as in male imago, except that segment II is tinged as segment I and conspicuous marks on segments VIII are also present on segment VII (Fig. 5). Gills grayish, tracheae black, a large basal lobe on inner lamella; seventh gill much reduced. Caudal filaments yellowish.
Etymology. The epithet of the new species is derived from the latin word for peace and is a reference to the peace process between the Revolutionary Armed Forces of Colombia (FARC) and the Colombian government. Thanks to that, this taxon could be finally collected, identified as a new species and properly described.
Life cycle association. Nymphs and adults were collected in the same area and both share the same and conspicuous abdominal color pattern.
