( Figs 3 , 9 ) Type material: Holotype : Burma : ♂ , Mandalay Region , Bagan , 21°09’N 94°53’E , 80 m , 10–14. & 22–24.X.2014 , leg. R . Fouquè, NMPC . Paratypes : Same data as for the holotype, 270 exx. NMPC , 7 exx. SMNS . Burma , Mandalay Region , Bagan , 21°09’N 94°53’E , 80 m , 2–8. V .2016, leg. R . Fouquè , 85 exx. NMPC . Description. Body length 4.0– 4.8 mm . Integument matt, blackish. Head short, round, length from cervical constriction to clypeus 1.3x of maximal width between eyes, rounded from cervical constriction to eyes, genae not surpassing eyes, with distinct, longitudinal bent impression, anterior margin of clypeus straight, symmetrical, frons without medial keel or impression, surface with dense but not confluent punctures, punctures diminishing on clypeus, each puncture with a light decumbent broad but acute seta. Eyes not prominent, completely in conture of head. Antennae 11-segmented, robust, shape of antennomeres as in Fig. 3 , antennomere 2 1.6x as wide as long, antennomere 3 1.4x as wide as long. Pronotum long, 1.3x as long as wide, widest at anterior corners, sides distinctly sinuated, posterior corners rectangular, anterior corners rounded, disc with two distinct parallel keels, keels punctured and with setation as on head, punctures sparser near lateral margins, surface besides keels without distinct setation; prothoracic hypomera with similar punctures as on disc and without setation. Elytra elongate-oval, widest in middle, 2.2x as long as wide, humeral corners protruding forward but not tooth-like, intervals 3, 5 and 7 with distinct complete keels, keel 2 shortened anteriorly and posteriorly, keels 1 and 3 not conjunct posteriorly, keels crenulated, suture slightly elevated, punctures in eight elytral rows distinctly larger than on pronotum, surface without distinct setation; scutellar strioles lacking; epipleura with a row of large punctures along entire length. Ventrites with finer and sparser punctures than on pronotum, punctures on last ventrite larger, denser than on anterior ventrites, punctures without setation. Legs without peculiarities. Aedeagus as in Fig. 9 . apicale parallel and with rounded apex, basale broader. Diagnosis. So far, three congeners are known from continental south-eastern Asia, which differ as follows: The widespread Gebieniella stenosides (Pascoe, 1862) ( type species of the genus) is larger, body length 6–7 mm , head longer, straight conical from cervical constriction to eyes, pronotum longer parallel and sides not sinuated, elytra with tooth-like humeral angles, aedeagus unknown. Gebieniella korshunovi Medvedev, 2009 , described from Thailand , is also larger, body length 6.2 mm , genae surpassing eyes, first antennomere very short, pronotal keels sinuated, aedeagus unknown. Gebieniella fouquei Ferrer & Lemaire, 2019 ), described from Cambodia , differs mainly by non-parallel pronotal keels, by the elytral keel 2 extremely shortened apically, aedeagus unknown. For separation of the species see also key and photographs in Ferrer & Lemaire (2019) . For differences to G. matthiasi sp. nov. see description below and Figs 3, 4 , 9, 10 . Etymology. Named after the daughter Ellena of René Fouquè. Remarks. Some specimens were mounted by René on a card together with ants, so very probably this species can be considered as myrmecophilous.
