description: Sanaungulus kirstenaeweissbachae sp. nov.   
(Fig. 13)  
 Holotype. Female, adult specimen in a Burmese (Kachin) amber piece: Catalog number SNHM­6007 in the Staatliches Naturhistorisches Museum Braunschweig (ex Müller’s collection number: BUB4483).   
 Type locality. Myanmar: Kachin state, Myitkyina District, Hukawng Valley.   
 Type horizon. Lowermost Cenomanian (98.79 ± 0.62 Ma), mid­Cretaceous.   
 Differential diagnosis. Sanaungulus kirstenaeweissbachae sp. nov. differs from Sanaungulus troelsikloevedali Fanti & Damgaard, 2019 based on its head that is slightly more transverse and a wider pronotum (Fanti & Damgaard 2019). Sanaungulus ghitaenoerbyae Fanti, Damgaard & Ellenberger, 2018 has the last antennomeres more robust and shorter than Sanaungulus kirstenaeweissbachae sp. nov. (Fanti et al. 2018). Sanaungulus kirstenaeweissbachae sp. nov. differs from Sanaungulus emarginaticollis Y.Yang, Liu & Bai in Y.Yang, Zhao, Geiser, W. Zhang, Ren, Bai & Liu, 2022 by its more transverse and different shape of the pronotum (Yang et al. 2022).   
 Description. Adult, winged, rather robust. Female, defined on the basis of the large last sternite. Body length 3.0 mm. Entirely brown.   
Head very transverse, constricted (triangular­shaped) behind the eyes, surface irregular with shallow punctation. Eyes prominent, very large, sub­elliptical, inserted in the lateral part of the head. Mandibles elongated, falciform. Maxillary palps 4­ segmented with the last palpomere elongated and securiform. Labial palps 3­ segmented, with the last palpomere securiform. Antennae 11­ segmented, pectinate, long, slightly surpassing the apex of elytra, antennal insertion far from the eyes; scape club­shaped, elongated, very robust; antennomeres II–III short, subequal in length, swollen apically; antennomeres IV– VII extremely long, each equipped at apex with an antennal process which is very long and thin with an emarginate apex; antennomeres VIII– X shorter than previous ones, not enlarged and robust, without the antennal process at apex; antennomere XI filiform, not enlarged and robust, long, with rounded apex; all the antennomeres slightly pubescent. Pronotum very transverse, approximately as wide as head, anterior margin undulate and slightly bordered, posterior margin almost straight and feebly bordered, sides rounded, corners obtuse, pronotum disc irregular with very shallow punctation. Scutellum narrow, triangular­shaped, pointed at apex. Elytra short which reveals some abdominal segments, at humeri wider than pronotum, posteriorly parallel­sided and very slightly dehiscent apically, rounded apexes, surface presenting a very coarse and wide punctation gathered in evident striae visible for the entire elytral length. Metathoracic wings transparent, longer than elytra, not reaching the last abdominal segment. Sternum very robust with margin almost straight; sternites transverse, wide and pubescent; last sternite very large and robust, rounded. Legs rather robust, relatively long, slightly pubescent; coxae massive; trochanters very elongated, robust, with rounded apex; femora almost straight, sub­cylindrical, slightly sturdier than tibiae; tibiae, thin, sub­cylindrical, with a small spur near the apex, protibiae approximately as long as profemora, mesotibiae longer than mesofemora, metatibiae shorter than metafemora. Tarsal formula 5­ 5­ 5; first metatarsomere extremely long, about 2.3 times longer than second; third tarsomere short; fourth strongly bilobed; fifth tarsomere elongated, thin, cylindrical and curved; claws simple, pointed, without denticle at the base.  
 Etymology. Named in honor of Kirsten Weissbach, dear friend of the second author (Patrick).   
 Syninclusions. Air bubbles, detritus, anAlydidae.   
 Remarks. Piece of clear, golden amber in Cabochon that measures 14x10x 4 mm. The inclusion is complete, with the head partially covered by emulsion.
