Differential diagnosis. Sanaungulus nilsi sp. nov. differs from other species of Sanaungulus with filiform antennae by its very elongated pronotum.
Description. Adult, winged, slender. Female, defined on the basis of short antennae and large abdomen. Body length 3.3 mm. Entirely brown with testaceous abdomen.
Head rounded, slightly constricted (triangularshaped) behind the eyes, equipped with dense pubescence and shallow punctation. Eyes prominent, large, roundish, inserted in the upper and lateral part of the head. Mandibles elongated, falciform, without teeth. Maxillary palps 4 segmented with the last palpomere very elongated and securiform. Labial palps 3 segmented, with the last palpomere elongated and securiform. Antennae 11segmented, filiform, robust, short, reaching half of elytra and the first abdominal segment, antennal insertion in the eyes proximity; scape robust, clubshaped; antennomeres II–III short, subequal, thinner than first; antennomere IV elongated, the longest; antennomeres V–X slightly shorter than antennomere IV, subequal, with antennomeres V– VIII sturdier than others; antennomere XI filiform, longer than previous ones, enlarged in the middle, rounded at apex; all the antennomeres with short pubescence. Pronotum very elongated, subrectangular, as wide as head, concave in the middle, anterior margin straight, posterior margin slightly undulated and strongly bordered, sides straight and bordered, corners obtuse, pronotum disc concave and pubescent. Scutellum triangularshaped. Elytra short which reveals various abdominal segments, at humeri slightly wider than pronotum, posteriorly parallelsided and slighty dehiscent apically, rounded apexes, surface pubescent and with a very small rugosity. Metathoracic wings longer than elytra, slightly surpassing the half of abdomen. Sternum elongated with posterior margin rounded, sternites large and transverse, last tergite elongated with rounded apex and narrower than penultimate tergite which is large and transverse, last sternite wide and enlarged at sides and slightly pointed apically. Legs thin, relatively long, pubescent; coxae massive; trochanters elongated, with rounded apex; femora slightly curved, more robust than tibiae, slightly flat; tibiae flattened, thin, with spurs near the apex, protibiae as long as profemora, mesotibiae slightly longer than mesofemora, metatibiae longer than metafemora. Tarsal formula 5 5 5; first tarsomere long, about 0.4 times longer than second; third tarsomere short and slightly bilobed; fourth strongly bilobed; fifth tarsomere elongated, thin, slightly flat and curved; claws simple, without denticle at the base.
