F12341AD0D1D5F9D980EA9789EB1EC84.taxon	diagnosis	Diagnosis. Larva. This new genus is distinguished by a combination of the following characters: A) body elongate and slender (Figs 24 a, 25 b); B) antennal scape distally with short, stout setae (Fig. 15 i); flagellum with basal segments parallel sided and thereafter inclined, giving the impression of a spiral arrangement (Fig. 5 a); C) labrum subrectangular, dorsally with a pair of long, simple submedian setae and a submarginal arc of long, simple setae (Fig. 14 a); D) right mandible with blade-like incisor, prostheca stick-like with distolateral dentation (Fig. 6 b); E) left mandible with blade-like incisor, prostheca robust, distally with denticles and comb-shape structure (Fig. 6 a); F) maxillary palp 2 - segmented, apex of segment II pointed; with accessory gill outside laterally between stipes and cardo (Figs 1 a, 18 h-j); G) labium with glossae basally broad, narrowing towards apex, shorter than paraglossae; paraglossae laterally slightly undulated, distally truncate and slightly bent inwards; labial palp with small to medium protuberance at segment II (Fig. 14 j); H) femora with stout setae both on anterior and posterior side, dorsal margin with row of medium to long, spine-like setae and straight row of medium, fine setae (Figs 3 a, b, 15 a, d); claw robust, pointed, with one row of denticles and usually a long, subapical seta (Figs 7 k, 15 e); femoral patch reduced on fore and middle legs, well developed on hind legs (Fig. 7 d-i); I) finger-like accessory gill ventrally between coxa and prosternum (Fig. 1 b); J) hind protoptera present, well developed; K) paraproct with spines at posterior margin (Fig. 15 h); L) seven pairs of tergalii (abdominal gills) on segments I-VII, anal margin with alternate short and long, fine setae (Fig. 15 g); M) subimaginal gonostyli developing under cuticle of last instar larvae folded in the following way: segment II sharply bent towards middle, last segment sharply bent laterally (Figs 4 a-d, 10 a, b). Imago. Forewing with double intercalary veins longer than the distance between corresponding longitudinal vein; pterostigma with numerous cross veins (Fig. 9 a, c). Hind wing with three longitudinal veins and well developed triangular costal projection (Fig. 9 d, e). Imaginal gonostyli: segment I of gonostylus with projected blunt angle proximad of its middle; segment III short and triangular (Fig. 10 d, e). Sterno-styligeral muscle present and thin (Fig. 10 f). The imago is known for a single species (B. javanicus comb. nov.). Therefore, it is unclear, which of its characters are species-specific and which can be considered as diagnostic for the new genus. The structure of hind wing and the presence of a thin sterno-styligeral muscle are also revealed for B. sabahensis comb. nov., based on details developing in last instar larvae.	en	Kaltenbach, Thomas, Kluge, Nikita J., Gattolliat, Jean-Luc (2022): A widespread new genus of Baetidae (Baetidae, Ephemeroptera) from Southeast Asia.

Imago. Forewing with double intercalary veins longer than distance between corresponding longitudinal vein; pterostigma with numerous cross veins (Fig. 9 a, c). Hind wing with three longitudinal veins and well developed triangular costal projection (Fig. 9 e). Imaginal gonostyli: segment I of gonostylus with projected blunt angle proximad of its middle; segment III short and triangular (Fig. 10 d, e). Sterno-styligeral muscle clearly developed, but thin (Fig. 10 f). The imago is known from a single species (B. javanicus comb. nov.). Therefore, it is unclear, which of its characters are species-specific and which are generic (e. g., shape of turbinate eyes). Ulmer (1913, 1924) and Mueller-Liebenau (1981) described imago and subimago and a complementary description is given below under B. javanicus comb. nov.	en	Kaltenbach, Thomas, Kluge, Nikita J., Gattolliat, Jean-Luc (2022): A widespread new genus of Baetidae (Baetidae, Ephemeroptera) from Southeast Asia.
