Libanobelostoma calineae Boderau, Nel, Maksoud, Abi-Saad & Azar, 2024, sp. nov.

Libanobelostoma calineae sp. nov. Figs 2–3 urn:lsid:zoobank.org:act: E7DC5698-97C5-42A7-828D-5348CAAA37BE Type material. Holotype I-26247/2A and B (part and counterpart of entire body), housed at the Natural History Museum of the Lebanese University. Diagnosis. As for the genus (vide supra). Etymology. The specific epithet honours Caline Abi Saad, wife of PAB, who found the new fossil. Locality and horizon. Lower Late Cenomanian, Haqel, Caza Byblos, Governorate Jbeil-Kesserouan, Central Lebanon. Description. Body rounded and flattened (Fig. 2A–B), 28.5 mm length; 10.6 mm, greatest width across abdomen; coloration pattern poorly preserved. Head short, ca. 1.6 mm long, 4.3 mm wide; one triangular eye preserved (Fig. 1A); anteclypeus rounded, ca. 8 mm long; clypeus triangular, two times shorter than anteclypeus; rostrum preserved ventrally (Fig. 1C–D; Fig. 2A–B), with three segments visible, lengths of rostrum segments one to three: 1.8 mm, 1.3 mm, and 0.3 mm. One antenna poorly preserved ventrally, three antennomeres with finger-like projections preserved for first two. Thorax 10.2 mm long. Pronotum with slightly convex lateral margins; pronotum and mesonotum subequal in length (0.21 mm). Scutellum triangular and longer than pronotum + mesonotum. Hemelytra incompletely preserved, with clavus and corium distinguishable, 15.8 mm long, no visible cells or veins, membranous area corresponding to at most one-third of wing. Forelegs raptorial-shaped with elongate and stout femur (4.55 mm), foretibia about twice shorter than forefemur and subequal in width with foretarsi, three tarsomeres; one preserved simple long claw (Fig. 2C–D). Middle legs poorly preserved with only middle femur visible, slightly enlarged, and one middle tibia. Hind legs long (ca. 12 mm), metacoxa conical, firmly united with metapleuron, femur slightly enlarged at base and narrower at apex, tibia apparently flattened, bearing few poorly preserved setae (Fig. 2F), hind tarsus short, with segmentation difficult to state. Abdomen robust and broad, 14.1 mm long, only abdominal segments V–-VIII distinguishable (Fig. 2E), air siphon incomplete, short, probably ca. 3.8 mm long.
