description: <i>Baeocera glabra</i> sp. nov. ( Figs 5–7) Holotype &amp;male; MHNG: Mindanao, Araibo, Pantukan, Compostela Valley, 900 m, Candalaga / Mts., 7°16’35.3’’N, 126°10’12.8’’E, 4.5.2019 Shavrin A. Paratypes 3&amp;male; PCAS &amp; MHNG: data as the holotype. Derivatio nominis: The species epithet is a Latin adjective meaning glabrous. Description: Length 0.88–0.91 mm, width 0.63– 0.65 mm. Frons and most of body blackish, apex of abdomen, femora and tibiae reddish-brown, tarsi and antennae ochraceous to yellowish. Body strongly convex dorsally. Bode strongly convex dorsally. Eyes in dorsal view slightly smaller than half of interval between them. Length/width rations of antennomeres as: III 16 /5: IV 17 /5: V 18 /6: VI 17 /5: VII 24 /8: VIII 18 /5: IX 25/10: X 25/10: XI 34 /10. Pronotum and elytra not microsculptured, with lateral contours continuously arcuate. Pronotum very finely punctate, with lateral margins rounded, lateral margin carinae concealed in dorsal view. Scutellum concealed. Elytra not overlapping abdominal apex, moderately narrowed apically, lateral margin carinae not visible in dorsal view, sutural striae entire, parallel, bent along pronotal lobe and extended along bases to form complete basal striae joined to lateral striae. Adsutural areas and sutural striae with few rather distinct fine puncture, discal punctation very fine, as that on pronotum, hardly visible at 100 times magnification. Hind wings fully developed. Hypomera appearing impunctate. Mesepimera about three times as long as wide and somewhat more than two times as long as intervals to mesocoxae. Metaventrite convex and impunctate in middle, with coarse punctures delimiting smooth centre; lateral parts of metaventrite smooth near metacoxae, coarsely and irregularly punctate on remaining surface. Mesocoxal lines slightly convex, with coarse puncture row extended laterally almost to mesepimera; mesocoxal areas about 0.02 mm, as third of shortest intervals to metacoxae. Exposed part of metanepisterna narrow, parallel, about 0.04 mm wide, with distinct, punctate suture. Metepimera each with longitudinal stria. Tibiae straight. Ventrite I without wrinkles, with basal row of coarse, to part slightly elongate punctures not interrupted in middle, punctation posterior of basal row extremely fine, hardly visible at 100 times magnification, as that on following ventrites. Male protarsomere I to III slightly widened. Aedeagus (Figs 5–7) 0.21–0.24 mm long. Differential diagnosis: This new species is a member of the <i>B. lenta</i> species-group and is similar to <i>B. danielae</i> LÖbl, 2012. It may be distinguished by the elytra entirely very finely punctate, in combination with the minute body-size and the internal sac lacking membranous denticles and bearing a proximally widened sclerite (seen in lateral view). [scale bar 0.1 mm].
