( Figs 4 View FIGURES 1–6 , 10 View FIGURES 7–12 )
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 GoogleMaps . Paratypes: Same data as for the holotype, 8 exx. NMPC, 1 ex. SMNS GoogleMaps . Burma, Mandalay Region, Bagan , 21°09’N 94°53’E, 80 m, 2–8. V GoogleMaps .2016, leg. R. Fouquè , 5 exx. NMPC , 3 exx. SMNS.
Description. Body length 4.3–4.5 mm. Integument matt, blackish. Head short, round, length from cervical constriction to clypeus 0.9x as maximal width between genae, slightly rounded from cervical constiction to eyes, genae distinctly surpassing eyes, with distinct and longitudinal bent impression, anterior margin of clypeus straight, symmetrical, frons without medial keel or impression, surface with separate punctures, punctures diminishing on clypeus, without distinct setae except microsetae at temporta. Eyes not prominent, completely in conture of head. Antennae 11-segmented and thick, shape of antennomeres as in Fig. 4 View FIGURES 1–6 , antennomere 2 1.7x as wide as long, antennomere 3 1.4x as wide as long. Pronotum subquadrate, 1.1x as long as wide, widest at anterior corners, sides slightly sinuated, posterior corners rectangular, anterior corners rounded, disc medially with longitudinal elevation bearing an oval impression, without keels, disc punctured as on head, punctures sparser near lateral margins, surface without distinct setation; prothoracic hypomera with similar punctures as on disc and without setation. Elytra elongate-oval, widest in middle, 1.8x 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 not larger and denser than on anterior ventrites, punctures without setation. Legs without peculiarities. Aedeagus as in Fig. 10 View FIGURES 7–12 . apicale basally constricted and with rounded apex, basale broader.
Diagnosis. Gebieniella matthiasi sp. nov. can be recognised mainly by small body size below 5 mm, by genae distinctly surpassing eyes, and by pronotum without keels but disc medially with longitudinal elevation bearing an oval impression. For separation of the species see also key and photographs in Ferrer & Lemaire (2019). The aedeagi cannot be compared, because the aedeagi of nearly all Oriental species (except Gebieniella ellenae sp. nov.) are unknown.
Etymology. Named after the son Matthias of René Fouquè.
Remarks. Several specimens were mounted by René on a card together with ants, so very probably this species can be considered as myrmecophilous.
