New country records for Macroscython granulosus Otto, 2016 (Coleoptera: Eucnemidae: Dromaeolinae: Dromaeolini), with redescription of the female Author Otto Jiří Háva, Robert L. text Insecta Mundi 2024 2024-11-29 2024 83 1 4 journal article 10.5281/zenodo.14719367 1942-1354 14719367 97C2B633-7D6C-4497-8E83-B9F18BAEFC42 Macroscython granulosus Otto, 2016 Figures 1–2 Macroscython granulosus Otto 2016: 305–306 , fig. 125. Differential diagnosis. The darker coloration of the integument along with granulose pronotal surfaces will readily separate M. granulosus from M. coomani . Specimens examined. Two specimens were studied: China : Yunnan Province : CHINA : S-Yunnan / (Xishuangbanna) / 20 km NW Jinghong / Man Dian (NNNR-office) // 22°07.80N , 100°40.05E / 740m , 26.V.2008 / leg. A.

Otto / 2022 ( 1 ♂ , NKME ) ; Nepal : Gandaki Province : Nepal , Gandaki prov. / Besishahar town 1.6.2023 / lgt. M. Janata & R . Sehnal ( 1 ♀ , JHAC ) . Redescription. Female. Length, 11.0 mm. Width, 3.5 mm. Body subcylindrical, elongate; uniformly dark reddish brown to dark brown; antennae and legs dark reddish brown; head, pronotum and elytra clothed with short, yellowish recumbent setae. Head. Subspherical; frons convex; apical margin of frontoclypeal region evenly rounded, less than 2.0 times wider than base; surfaces dull, granulose; mandibles stout, bidentate, densely punctate and rugose. Antennae. Strongly serrate, extending nearly as long as 1/2 the length of body; flagellomere I longer than wide, slightly longer than II; flagellomere II longer than wide, slightly longer than III; flagellomeres III–VIII each longer than wide, subequal. Pronotum. Basal 3/4 parallel-sided, apical 1/4 arcuate; wider than long, with moderate, sharp hind angles; disc convex; surfaces dull, granulose; base sinuous. Scutellar shield. Somewhat shiny, closely punctate, oblong, subtriangular and distally rounded. Elytra. Strongly striate; interstices elevated with close, dense punctations. Legs. First tarsomere shorter than the combined lengths of the remaining four on mesothoracic and metathoracic tarsi; tibiae rounded in cross section; metathoracic tarsomeres I–III simple; metathoracic tarsomere IV excavate-emarginate; metathoracic tarsomere V elongate; pretarsi with basally toothed claws. Venter. Sparsely punctate, with very short, yellowish recumbent setae; prothoracic hypomera with shallow, medially vaguely defined, posteriorly open lateral antennal grooves; metathoracic episterna parallel-sided; metathoracic coxal plates medially 3.0–6.0 times wider than laterally. Distribution. This rarely encountered eucnemid species has been previously taken in and reported only from Laos and Thailand . New records are here confirmed for China and Nepal . Figures 1–2. Macroscython granulosus Otto , female. 1) Dorsal habitus. 2) Antenna (body length 11.0 mm). Biology. Developmental stages remain unknown for this species. Adults from Laos were taken from a northern annamites rainforest, northern Indochina subtropical forests and southern annamites montane rainforests ( Dinerstein et al. 2017 ). One specimen was taken at light in China . Note. An interactive map (ecoregions2017.appspot.com) was embedded within the article written by Dinerstein et al. (2017) , which allowed for identification of the general ecoregion from which the eucnemid species was taken in Laos .
