Aristovia gen. nov., here designated.	en	STOROZHENKO, SERGEY YU., GRÖHN, CARSTEN (2023): A new family of grylloblattids (Insecta: Grylloblattida) from mid-Cretaceous Burmese amber. Palaeoentomology 6 (2): 165-173, DOI: 10.11646/palaeoentomology.6.2.8, URL: http://dx.doi.org/10.11646/palaeoentomology.6.2.8
03C02B74631B1E40FF2C78FBFCD8F8D5.taxon	diagnosis	Diagnosis. The new family is most similar to the Early Permian – Middle Triassic Megakhosaridae and the Middle Permian – Middle Jurassic Blattogryllidae in the large head with relatively large compound eyes and three small ocelli, filiform multi-segmented antennae, orthopteroid mouthparts, 5 - segmented tarsi, and wing venation, but differs from both by lacking the paranotalia (lateral expansions of the pronotum) and by Sc ending on RA near the apex in both fore- and hind wings. In Megakhosaridae and Blattogryllidae, the ring of paranotalia is always present and Sc ends in C. The new family is also similar to the wingless Grylloblattidae but easily recognizable from it by the lack of the strong transverse furrow separating the anterior part of pronotum from its posterior part, the character typical for all known extant species of Grylloblattidae.	en	STOROZHENKO, SERGEY YU., GRÖHN, CARSTEN (2023): A new family of grylloblattids (Insecta: Grylloblattida) from mid-Cretaceous Burmese amber.

CuA – CuP area without crossveins. Anal veins simple. Legs (Fig. 4 C, D).

Mid leg similar to fore leg; femur 2.4 mm long; tibia 2.7 mm long, tarsus 5 - segmented, apical segment with long tarsal claws, length of claw 0.5 times 5 th segment (Fig. 4 D).

Eggs (Figs 2 B, 4 E, D). Lengths 1.5 – 1.6 mm. Capsule elongate; in lateral view, the ventral side S-shaped while dorsal side almost straight; lateral sides with three low longitudinal ridges. Operculum broadly oval. Composition. Family consists of a type genus only. Stratigraphic range. The lowermost Cenomanian, mid-Cretaceous, ca. 98.79 ± 0.62 Ma (Cruickshank & Ko, 2003).	en	STOROZHENKO, SERGEY YU., GRÖHN, CARSTEN (2023): A new family of grylloblattids (Insecta: Grylloblattida) from mid-Cretaceous Burmese amber.
