F55BC91937A15F348681EE1283FCDD22.taxon	description	Description. Body length from clypeus to the last abdominal segment (excluding urogomphi) 2.41 mm. For other measurements see Table 3. Body habitus and pubescence (Fig. 1 A, B): Body elongate, whitish, sclerotized parts brown. Head capsule, urogomphi and dorsal part of abdominal segment IX heavily sclerotized, dark brown (urogomphi lighter than tergite IX); prosternum, protergum and mesotergum with sclerotized brown plates; metathorax and abdomen up to segment VIII whitish. Cranium with long sparse pubescence dispersed irregularly (c. 50 - 60 setae on dorsal side and c. 20 setae on ventral side); dorsum of thoracic segments with c. 10 - 15 long setae; legs with few long setae; abdominal segments I-VIII with dorsally about 2 - 4 long and laterally about 5 setae; sides of abdominal segments IX-X with dense and long pubescence, urogomphi also with long setae. Ventral sides of thoracic and abdominal segments with shorter and sparser pubescence. - Head: Cranium approximately as wide as long, lateral sides weakly rounded (convex), its anterior margin wider than base (Table 1; Figs 1 C, 4 C); five stemmata occur on each side with the formula 2 + 3 (two posterior and three anterior) (Fig. 2 C); frontal arms distinctly Y-shaped, with branches curved at half their length and divergent (Fig. 4 C); median endocarina absent (Fig. 1 C); frontoclypeal suture present (Fig. 1 A, C); gular sutures widely separated, subparallel, virtually extending to anterior part of cranium (Fig. 5); hypostomal rods absent; paragular sclerites absent. Gular region membranous and pale, its middle part nearly reaching midpoint of cranium so that the maxillolabial complex reaches slightly beyond half of cranium; head capsule is ventrally open, without bridge along anterior margin (Figs 1 D, 5). - Antennae (Figs 1 D; 2 B, D): 3 - segmented, 1 st antennomere shorter than 2 nd, the latter obliquely truncated and shorter than 3 rd; sensory appendix relatively short and stout, triangular, not extending behind one quarter of 3 rd antennomere, which is relatively slender and long, with long seta on apex. - Mandible (Figs 1 D, 2 A): bidentate (Fig. 2 A), that is with two apical teeth situated side by side; other mandibular structures not visible in fossil. - Maxilla (Figs 2 D, 5): mala small, triangular, with at least 3 thick long setae along outer margin; pedunculate seta not observed; palpi 3 - segmented, 1 st and 2 nd palpomeres equal in length, terminal palpomere coniform and longer than 1 or 2; cardo and stipes distinctly separated; cardo narrow and transverse, much smaller than stipes (Fig. 5). - Labium (Figs 1 A, 2 A, 5): ligula small, pale, membranous, ciliate, rounded; palpi 2 - segmented, terminal palpomere cylindrical, about twice as long as basal palpomere; prementum in single part (not divided); border of postmentum not conspicuous. - Labrum (Figs 1 C, 2 E, 5): free; anterior margin wide and convex, with about 6 long setae (Fig. 5); other details not visible. - Thorax (Fig. 1 A, B, C): protergum heavily sclerotized and pigmented, with single large tergal plate longitudinally divided by medial suture; mesotergum with pair of small but distinctly pigmented and sclerotized tergites; structure of metatergum the same as that of mesotergum, but sclerites slightly smaller (Fig. 1 C). Ventral part of pro-, meso- and metathorax without distinctly pigmented sclerites. - Legs (Fig. 1 B, C): Coxae projecting; trochanters rather triangular; femora longer than tibiae; tarsunguli without visible setae. - Abdomen: segments I-VIII membranous, their terga without sclerites (tergites) or pigmented plates (Figs 1 A, 2 E); segment IX with single tergite (not transversely divided into two parts) bearing a pair of slender hooked urogomphi (Fig. 2 E); median process or glandular openings on or between urogomphi not visible, but it is possible that a pair of membranous appendages are present approximately at the centre of tergite IX; urogomphi without large tubercles, relatively slender, conspicuously turned upwards, well-developed (Fig. 1 E; cf. Fig. 3 B, D).	en	Kolibac, Jiri, Rosova, Katerina, Prazak, Jan Simon, Hammel, Joerg U., Prokop, Jakub (2023): The first larva of the cucujiform superfamily Cleroidea from the Mesozoic and its ecological implications (Coleoptera).

BA3CA54E53B3506BB248A9808FA65395.taxon	diagnosis	Diagnosis. Cranium weakly trapezoidal, approximately as wide as long, its anterior margin wider than base (Figs 1 C, 4 C); head capsule ventrally open, with long gular sutures (Figs 1 D, 5); five stemmata present on each side, with formula 2 + 3 (Fig. 2 C, D); terminal antennomere slender and longer than the previous one (Figs 2 D, 5); dorsal side of prothorax with single sclerotized tergal plate divided longitudinally with suture; meso- and metatergum with a pair of distinct tergites (Fig. 1 A, C); urogomphi slender, hooked (Fig. 1 E), without distinct glandular openings, processes or tubercles (a pair of membranous appendages might be present at centre of abdominal tergite 9).	en	Kolibac, Jiri, Rosova, Katerina, Prazak, Jan Simon, Hammel, Joerg U., Prokop, Jakub (2023): The first larva of the cucujiform superfamily Cleroidea from the Mesozoic and its ecological implications (Coleoptera).

BA3CA54E53B3506BB248A9808FA65395.taxon	etymology	Etymology. The generic name is composed of the prefix creto - (derived from Cretaceous period) and the root rhadalus that denotes the supposed affiliation of the new genus with the family Rhadalidae, not a relationship with the nominate genus. Gender of name is masculine.	en	Kolibac, Jiri, Rosova, Katerina, Prazak, Jan Simon, Hammel, Joerg U., Prokop, Jakub (2023): The first larva of the cucujiform superfamily Cleroidea from the Mesozoic and its ecological implications (Coleoptera).
