Ventral surface of stipes with single proximal and one distal seta. Galear portion of mala in dorsal aspect beside large falcate uncus with four to ¿ve large stiff and three to ¿ve medium sized hair-like setae respectively. Lacinial part of mala with around 15–20 mostly long and stiff setae. Lacinial apex with single triangular uncus with two short conical, stout setae at the base and another single long, conical setae next to it. Ventral surface of mala with two longitudinal rows of three to four (seven) setae; setae of the exterior row long and stiff, setae of the interior row shorter and stout. Hypopharyngeal sclerome (Fig. 5B). Around ¿ve tegumentary expansions (phoba-like processes) present on the left lateral lobe of hypopharynx, the presence of tegumentary expansions on right medial portion scleroma individually variable. Ligula (Figs 5B; 13B). Dorsal surface with two lateral groups of around 10 hair-like setae, two paramedial setae at the apical margin and central group of setae and sensilla. This group is composed of two paramedial rows of approximately three stout and conical setae, and transverse, basomedial row with seven to eight conical setae. Thorax (Figs 2B; 6Q; 7T; 9N). Prothoracic sclerite with four (three) setae on the anteroventral margin and another single seta in the posterio-dorsal area. Each sublobe of prothorax dorsally with one or two rows of mostly short or medium-long setae interspersed with few long, hair-like setae. Thoracic spiracle (Fig. 6Q) 0.93 × 0.59 mm (height × width), bullar opening narrow, arms of respiratory plate almost concealed. Respiratory plate with approximately 30 holes across diameter. Venter of thorax and legs with spatulate setae. Pretarsus (Fig. 7T) conical with large falcate tip and two apical setae. Abdomen (Figs 2B; 10B; 11B). Each dorsal sublobe of abdominal segments I–VIII with two to three rows of setae. Setae in anterior row(s) short or medium-sized, posterior row also with several long setae. Dorsum of abdominal segment IX–X, as well as the entire ventral part of abdomen covered with spatulate medium-long setae. Spiracles on abdominal segments I–VI elongate, similar to thoracic spiracle, abdominal spiracles on segments VII–VIII almost circular. Raster (Figs 10B; 11B). Rows of pali absent, tegilla fused, covered with numerous short or medium-long spatulate setae.Published as part of Vendl, Tomáš, VONDRÁýEK, Dominik, Kubá, VítČzslav & Šípek, Petr, 2014, Immature stages of Taenioderini (Coleoptera: Scarabaeidae: Cetoniinae): a report of hidden morphological diversity, pp. 571-604 in Acta Entomologica Musei Nationalis Pragae 54 (2) on pages 580-582, DOI: 10.5281/zenodo.530116
