TYPE LOCALITY: Myanmar: Kachin: near Tanai Village . Albian-Cenomanian boundary .

TYPE: Holotype AMNH Bu-1418, alate male in a 4 × 7 × 1.5 mm rectangular, yellow, transparent polished amber piece with a large crack passing through the specimen; specimen well preserved but only lateral views observable. Myanmar, Kachin, Tanai Village, on Ledo Road, 105 km NW Myitkyna), Leeward Capitol Corp coll., deposited in the American Museum of Natural History.

ETYMOLOGY: The epithet is from Latin glaesum to mean “of amber”.

DIAGNOSIS: As for genus.

DESCRIPTION: Body small, total length 1.37 mm long, widest width not measurable. Head (fig. 16A): Frontally flat ca. 290 μm wide, 140 μm long. Head structures not visible except for an ocular sclerite that surrounds head, each bearing seven pairs of large, protruding simple eyes. Antenna (fig. 16B): 10-segmented, total length 950 μm; segment lengths (in μm): scape ca. 45 μm long; pedicel, 80 μm long, with several whorls of long setae (ca. 65 μm); segments III–X all filiform: III 93; IV 122; V 100; VI 95; VII 115; VIII 100; IX 100; X 100. Antennal setae longer than segment width (55–65 μm long). Differentiated setae on apical segment not observed. Thorax: Head and thorax separated by a narrow neck constriction. Prothorax membranous. Ridges on prothorax not observable. Dorsally: prescutum round and bulging anteriorly, other thoracic structures not clear. Wings (fig. 15A): Forewings well developed, round with broad base and a rounded apex; 1.28 mm long, 640 μm wide; subcostal ridge extending from base of wing to more than 3/4 wing length. Cubital ridge 200 μm from wing base, extending to same level as subcostal ridge. Posterior flexing patch not observable Wing covered with microtrichia; alar setae present, sensoria not observed. Alar fold present. Hamulohalteres broad, each with two hamuli. Legs (fig. 16C): Long and slender, all of subequal length; prothoracic leg: coxa triangular, 70 μm long; trochanter and femur fused, ca. 300 μm long, 30 μm wide on prolegs; tibia: 280 μm long, 28 μm wide, with multiple tarsal spurs, tarsus 2-segmented, 160 μm long, and 20 μm wide, tarsal digitules absent; claw narrow almost straight, 30 μm long, claw digitule spinelike, claw denticle absent. Abdomen: Cylindrical, 700 μm long (440 μm without genital segment). Setae are visible but frequency and distribution uncertain. Abdominal segment VIII with a pair of glandular pouches laterally, each extruding two long wax filaments. Genital segment (fig. 16D): Penial sheath elongate triangular, about 245 μm long, with a few setae anteriorly. Aedeagus narrow, almost as long as penial sheath, pointed.
