A0632F05551B51B9829B94B48E534797.taxon	diagnosis	Diagnosis. — Pronotum with two distinct grooves. Anterior groove smooth, posterior groove sharp. Brachypterous. Last abdominal tergite consisting of 5 – 7 plates. Supraanal plate elongate, triangular. Sub-genital plate bulbous with apical central fold and lateral cercus-like lobes. Cercus slender, same length as supra-anal plate. Cercus and sub-genital plate setulose. Only dorsal (= middle) plate of last abdominal tergite setulose.	en	Husemann, Martin, Schall, Ole-Kristian Odin, Uchida, Kei, Kotthoff, Ulrich (2025): The first Cretaceous Eumastacoidea (Orthoptera, Caelifera) from Burmese amber.

19A194A15E67579E9D7A2C23368C5336.taxon	description	Description. — Body long and slender, about seven times as long as high. Body length (tip of head to tip of abdomen) 7.53 mm; 1.03 mm high (measured right in front of metathoracic leg). Head. — Twice as high as wide and twice as high as body height. Top of head capsule to bottom tip of mouth parts, 2.05 mm; 1.03 mm width at widest point (eye level). Fastigium not elongated. Eyes large, ellipsoid, and laterally protruding from head. Eyes take up almost half the head height and are about twice as high as wide. Eye top to bottom 0.87 mm long, 0.45 mm wide. Distance from bottom of the eye to bottom of the head, 1.2 mm. Interocular distance (measured at top of head), 0.32 mm. Antennae missing except antennal bud, which is 0.32 mm long and reminiscent of a pinecone with scales closed. Antennal bud located right in front of the bottom of the eyes. Lower face slightly oblique in profile with mouthparts forming a cone or almost triangular shape. Right maxillary palpus 7 - segmented, 0.87 mm long in total. Thorax. — Thoracic height 1.06 mm, of which 0.58 mm is covered by the pronotum. Pronotum 1.31 mm long dorso-laterally, slightly shorter at 1.12 mm ventro-laterally. Pronotum saddle-like, covering the thorax with distinct elevation. Pronotum marked by two distinct grooves on its dorsal surface, one smooth anteriorly, second sharp posteriorly. Wings. — Brachypterous. Short wing buds can be seen sticking out from under the posterior margin of the pronotum. Wing buds ca. 0.42 mm long. Legs. — Prothoracic leg: only preserved up to femur. Long and slender. Preserved part 1.64 mm long. Mesothoracic leg: only preserved up to femur. Long and slender. Preserved part 2.36 mm long. Metathoracic leg: femur very long, length / width ratio 4.2 mm / 0.77 mm = 5.5; thinning distally. Tibia thinning further along its length of more than 4 mm (metatibia not fully preserved) until it shares a width similar to pro- and mesofemur. Dorsal margin of metafemur on proximal half with spaced short fine hairs, which are replaced by small spines on distal half. Spines continuing along the dorsal margin of metatibia and getting larger distally (0.03 mm – 0.12 mm). Dislocated object in bottom left area probably left metatibia: 4.04 mm long (including three spines at distal end; these spines may be the apical spines of the metatibia). Abdomen. — Abdomen with a distinct hump at the position of metathoracic legs. Last abdominal tergite made up of five to seven individual plates that cover the dorsal part of the genitalia like a ring. Dorsal (= middle) plate setulose. Supra-anal plate elongate, triangular. Sub-genital plate bulbous with central fold apically and lateral cercus-like lobes. Real cercus slender, ca. 0.47 mm long. Sub-genital plate and cercus setulose.	en	Husemann, Martin, Schall, Ole-Kristian Odin, Uchida, Kei, Kotthoff, Ulrich (2025): The first Cretaceous Eumastacoidea (Orthoptera, Caelifera) from Burmese amber.
