Etymology. The specific epithet honors Jean-Marc Pouillon who allows the study of the type specimen; it is to be treated as a noun in genitive case.
Material. A complete adult, preserved in a flattened, blurry, reddish amber piece (20 mm × 7 mm × 6 mm); holotype specimen accession number IGR.BU-058, housed in the amber collection of the Geological Department and Museum of the University of Rennes, France (IGR).
Locality and horizon. Noije Bum Hill, Hukawng Valley, Kachin State, Myanmar; upper Albian to lower Cenomanian, mid-Cretaceous.
Diagnosis. Forelegs with stout trochanter, femora with nine spines on outer edge, two spines on inner edge, tibia with parallel sides, probasitarsomeres with around six pairs of black and thick spines; wings elongate and narrow, forewings with costal veinlets simple before ScP and RA fusion, coloration pattern present i.e. with spots of color around crossveins and no marking near wing margin, only 3ra-rp present, scp+ra-rp1 present, RP with four branches, one inner gradate crossvein i.e. 2rp3-rp4 present; hind wings with ra-rp crossvein located proximad separation of RP1 and RP2, four RP branches, inner gradate crossveins present i.e. 2rp2-rp3, 3rp3-rp4. Male genitalia: Tergum IX short, nearly half length of tergum VIII, posteriorly concave; sternum IX bulbous; ectoproct paired, slightly elongate, bulbous, longer than tergum IX; gonocoxites X paired, digitiform, with spinous tip, slightly sclerotized, curved upward and directed laterally; gonostylus X digitifrom, distinctly curved dorsad.
Description. Male. Body length ca. 6.80 mm as preserved (Fig. 1A). Head ca. 1.36 mm wide (including eyes) (Fig. 2A). Vertex covered with fine setae. Eyes large, ca. 0.45 mm wide and ca. 0.48 mm high in ventral view (Fig. 2A), protruding laterally. Antennae with scape slightly elongate, ca. 0.21 mm long and ca. 0.09 mm wide, about twice as long as wide; pedicel about twice shorter than scape, both covered with fine dense setae; flagellum moniliform, with at least 30 flagellomeres, all with scattered fine setae, apical one tapering toward apex (Fig. 1A). Pronotum 2.26 mm long and ca. 0.45 mm wide (near mid-length), elongate, slightly narrower than maximum width of head, covered with sparse, long setae (Fig. 1A). Length of mesothorax + metathorax combined ca. 1.33 mm.
Legs. Procoxa elongate similar to profemur in length. Protrochanter stout and short. Profemur long, ca. 1.61 mm, in lateral view broadest basally and tapering toward junction with tibia, covered with dense fine setae (Fig. 2B), mostly on dorsal surface, with spines of variable lengths forming two rows on ventral edge, nine spines on outer margin (Fig. 2D), two spines on inner margin. Protibia long, ca. 1.47 mm, slender, not thinning in distal third (i.e. with parallel sides), inner edge with row of stout prostrate setae, sharply curved distad and numerous thin setae, dorsal and lateral edges with sparse sedation of variable length (Fig. 2D). All protarsomeres covered with fine setae; probasitarsomere longest, with numerous spines on ventral edged (Fig. 2C), II-IV tarsomeres with a pair of stout spines (Fig. 2C); lengths of tarsomeres from base to apex (in mm) 0.31, 0.09, 0.07, 0.08, ca. 0.14; claws stout, curved. Mesocoxa stout and conical. Mesofemur long, ca. 1.33 mm, slender, covered with dense long setae. Mesotibia long, ca. 2.06 mm, slender, covered with dense long setae, several long stronger setae, with distinct coloration pattern, i.e. three dark stripe (distal one at apex); all mesotarsomeres covered with fine setae, spines or strong setae present on ventral surface; first tarsomere the longest; combined length of tarsomeres ca. 1.01 mm; claws small, curved. Metacoxa similar to mesocoxa. Metafemur long, ca. 1.4 mm, slender, covered with dense long setae. Metatibia long, ca. 2.76 mm, slender, covered with dense long setae, several long stronger setae, with two dark stripes, one distally and one in distal part of basal third; all metatarsomeres covered with fine setae, spines or strong setae present on ventral surface; first tarsomere the longest; combined length of tarsomeres ca. 1.06 mm; claws small, curved.
Forewing (Figs. 1B, 2E, 3) with conspicuous coloration pattern along crossveins and pterostigma, elongate, ca. 7.07 mm long, ca. 1.84 mm wide. Trichosors present nearly along whole wing margin (absent basally); thin setae sparsely present on dorsal and ventral surfaces of longitudinal veins, but absent on crossveins. Humeral veinlet simple; costal space thin; all subcostal veinlets simple before ScP and RA fusion, after forked; ScP fused with RA in apical third; subcostal space with proximal crossvein (1scp-r) located slightly distad R fork; RP divided into four branches; RP1 not deeply forked; crossveins scp+ra-rap1 and 3ra-rp present; no crossvein between RP1 and RP2; 4rp2-rp3 present before RP2 and RP3 branching; 2rp3-rp4 and 4rp3-rp4 present; 1r-m present slightly anteriad 1mcua (Figs. 2E, 3); 1rp-ma slightly distad M fork; 4rp4-ma present between anterior branch of MA and stamp of RP4; M deeply forked, 4ma-mp present; Cu deeply forked, 1mp-cua slightly distad M fork, 3mp-cua present between MP and anterior branch of CuA, 2cua-cup present; 1cup-a1 located anteriad CuP or A1 forks; A1 forked near wing margin; 1a1-a2 crossvein present; A2 with several branches; A3 present simple(?). Hind wing (Figs. 1C, 3) with coloration only around 3ra-rp, elongate-ovoid, ca. 6.50 mm long, ca. 1.58 mm wide. Trichosors nearly present along whole wing margin (absent basally); thin setae sparsely present on dorsal and ventral surfaces of longitudinal veins, but absent on crossveins. Costal space extremely narrow; subcostal veinlets mostly simple until ScP and RA meeting point, then forked; ScP fused with RA in apical third of wing; subcostal space without crossvein; RP divided into four branches; intra-RP crossveins present; one ra-rp crossveins present (3ra-rp) located after dichotomy of RP1 and RP2; 2rp2-rp3, 4rp2-rp3, 3rp3-rp4, and 4rp3-rp4 present; M divided into MA and MP; two crossveins present between RP and M i.e. 2rp4-ma and 4ma-mp, first one slightly anteriad M fork, second between anterior branch of MA and RP4; origin of Cu unclear; CuA and CuP pectinately branched; one crossvein (1cua-cup) present; one mcua crossvein present; one mp-cua crossvein present; anal veins present but hardly discernible.
Abdomen about 2.5-3 mm long, slender, slightly compressed laterally, slightly thinner anteriorly, with moderately scattered setae. Male genitalia: Tergum IX short, nearly half length of tergum VIII, posteriorly concave; sternum IX bulbous; ectoproct paired, slightly elongate, bubous longer than tergum IX; gonocoxites X paired, digitiform, with spinous tip, slightly sclerotized, curved upward and directed laterally; gonostylus X digitifrom, distinctly curved dorsad.
