Haploglenius abdominevittatus Ardila & Jones , n. sp.

Etymology: abdomen, -inis, Latin, abdomen; vitta, -ae, Latin, ribbon, stripe. Literally, striped abdomen, referring to the pale bands encircling the anterior portions of the abdominal segments.

Diagnosis. Costal field of both wings hyaline; subcostal field with translucent brown maculation subtending each subcostal veinlet; pterostigmata dark brown; wing membranes hyaline; forewing axillary angle prominent and acute; posterior margin of the forewing posterad of the axillary angle with a strong concavity; distinct pattern of pale bands running transversely on anterior half of each abdominal tergite. A small and pubescent pronotal flap present.

Description. Holotype. Male. Body length: 29 mm. Forewing length: 36 mm. Hind wing length: 33 mm. Width of head: 6.5 mm. Interocular distance: 2 mm. Antennae length: 28 mm.

Head. Clypeus light brown, labrum ocher, with setae at the distal edge ocher and black. Frons light brown, covered with white setae, prefrontal region brown, with long setae, black and white ( Fig. 1 e). Vertex dark brown, covered with gray and black setae, occiput dark brown. Eyes gray, entire, without transverse groove. Mandible base pale ocher, changing to reddish brown apically, maxillary palps pale ocher, with black setae in the third and fourth palpimere. Galea and lacinia long, densely covered with ocher setae at the apex. Base of labial palps pale ocher, changing to red ocher distally. Antennae long, dark brown, reaching laterally beyond the fourth branch of Rs with 58 to 60 flagellomeres, the first six with short dark brown setae on the distal margin, scape and pedicel light brown, club fusiform, reddish brown dorsally and light brown ventrally, composed of 14 segments, covered with black setae ( Fig. 1 h).

Thorax. Pronotal flap developed, small, dark brown, with long black setae on the distal margin, the rest of its surface with ocher setae. Mesonotum dark brown, covered with long black and ocher setae; metanotum gray-brown with pale ocher setae ( Fig. 1 f). Pteropleuron predominantly dark brown, subalar stripes lacking, with black and ocher setae on the mesopleuron and white setae on the metapleuron ( Fig. 1 g).

Legs. Coxae dark brown, covered with white setae. Trochanter and femur ocher ventrally, becoming brown apically, covered with black setae, setae very long on the femur. Tibial bases brown, changing to ocher apically, covered with long black setae, dorsally ocher. Tibial spurs reddish brown, long, reaching the third tarsomere. The first four tarsomeres reddish brown, the last ocher, all covered with black setae. Empodium tab-shaped, spurs brown, almost as long as fifth tarsomere.

Wings. Fore- and hind wings elongated and narrow, membranes hyaline. Costal area hyaline, subcostal area with a translucent brown maculation subtending each subcostal veinlet. Pterostigma composed of three to four dark brown cross veins in both wings ( Fig. 1 b, c), stigmal membranes translucent brown. Wing apices rounded.

Venation dark brown, 9 presectoral crossveins in forewings, 7 in the hind wings. Rs with six forks in both wings, apical field of both wings consisting of three to four oblique irregular inner rows of cells surrounded by a row of cells lining wing margin. Cubital fork of forewing distinct, starting at the position of the eighth presectoral cross vein. Hind margin of the forewing with an acute axillary angle, followed by a prominent concavity ( Fig. 1 b). CuA fork in the hind wing distinctive, with the posterior branch perpendicular to the wing axis. Hind wing with three rows of anal cells ( Fig. 1 c).

Abdomen. First tergite brown, covered with long black setae, abdominal acrotergite reduced. Second tergite brown, with long brown setae ( Fig. 1 d). Tergites of abdominal segments 3 to 6 pale brown anteriorly, changing to dark brown toward the posterior region. Tergites 7 and 8, dark brown with white spots on both sides of the proximal region near the pleural region. A small pluritocavae in the 7th segment, at the level of spiracle. All segments covered with black setae.

Male Genitalia. Ectoproct brown, covered with long black setae and with a patch of thin and short setae on its surface, three rows of long and dark brown setae on the distal margin ( Fig. 2 a). Sternite 9 covered with black setae, very long on the posterior margin ( Fig. 2 b). Pulvinus short with approximately 20 straight gonosetae, a setimere at the apex about two times longer than this; parameres brown, elongate and acuminate ( Fig. 2 c), gonarcus and apodeme well developed ( Fig. 2 e). Pelta present.

Geographical Record. Colombia (Orinoco), Vichada, Tuparro National Park.

Adult Flight Period. Individual was collected during the month of August.

Bionomic data: The adult specimen described here was collected in a forest gallery neighboring the administrative center of El Tuparro National Natural Park (Parque Nacional Natural El Tuparro). It was taken during the morning hours as it rested in the vegetation near small, lotic water source.

Type Material. Holotype male: Colombia, Vichada, PNN Tuparro, Centro administrativo, 05° 20’ 57” N 67° 51’ 38” S, 140 msnm, 8–28.viii.2000 w. Villalba (ICN-049265)/ Haploglenius abdominevittatus . Det. J.A. Ardila 2010. (Printed on rectangular white paper).

The type specimen is deposited at the National Institute of Natural Sciences (MHN-ICN), Universidad Nacional de Colombia, Bogotá D. C. Holotype condition: good, pinned, wings spread. Male terminalia dissected, stored in a microvial with glycerine.
