B02BD8CBB01D5895816C4E9FB695D8A7.taxon	description	Description. Body elongate, covered with rounded tubercles. Head prognathous, elongate, constricted posteriorly to form a neck; dorsal surface without prominent posterior protuberances (Fig. 3 A). Compound eyes protruding laterally (Fig. 5 H). Antennal insertion area located anterolaterally. Antennal grooves absent. Postocular temples not prominent. Antenna 11 - segmented, short, extending beyond anterior prothoracic margin when posteriorly directed, but not reaching posterior prothoracic margin, with thin and short setae; antennomere 1 wider than other antennomeres; antennomere 2 distinctly small, subquadrate, about as wide as long; antennomere 3 elongate, 2.6 times as long as 4; antennomeres 4 - 10 short, subequal in length; antennomere 11 tapering apically. Mandibles probably with vertical cutting edges (Fig. 5 A). Gula sutures long, (almost) reaching posterior edge of head (Fig. 4 A). Pronotal disc subtrapezoidal, with maximum width near base, distinctly narrower than hind body (Fig. 3 B); lateral edges dentate (Fig. 5 D). Pronotal hypomeron very narrow. Propleura reaching anterior margin of prothorax (Fig. 4 B). Prosternum (Fig. 4 B) comparatively large, quadrate; prosternal process short. Procoxae contiguous. Elytra elongate; each elytron with probably ten longitudinal rows of transverse maculated window punctures on disc and two rows of larger maculated window punctures on explanate epipleuron (Fig. 3 C-F); longitudinal ridges (elytral veins) indistinct, with rounded tubercles (Fig. 5 F). Mesoventrite with discrimen on posterior half (Fig. 4 C). Mesocoxae contiguous. Metaventrite subtrapezoidal, with discrimen and katepisternal suture (Fig. 4 D). Metacoxae transverse, contiguous. Abdomen broad, with five coplanar ventrites, separated by distinct grooves; ventrites 2 - 5 subequal in length (Fig. 4 E, F); ventrites 5 with a slightly raised non-tuberculate circular region in the middle (Fig. 5 I).	en	Li, Yan-Da, Tihelka, Erik, Pang, Hong, Huang, Di-Ying, Cai, Chen-Yang (2021): Limnomma, a new genus of Ommatidae from the Middle Jurassic Daohugou beds (Coleoptera, Archostemata).
