038887CDFFB5FFB3FC9A00DAFE29561A.taxon	description	Description. Body elongate, parallel-sided, 1.93 mm long, 0.54 mm wide, covered with distinct setae. Head (Fig. 4 A, B) prognathous, without distinct neck; dorsal surface with a pair of longitudinal protuberances. Compound eyes lateral, entire, with short interfacetal setae. Antennal insertions dorsally located (Fig. 4 A), separated by less than twice diameter of antennomere 1. Antennae 11 - segmented, long, almost reaching elytral apex when posteriorly directed; antennomere 1 long and wide; antennomere 2 shorter; antennomere 3 – 8 elongate; antennomeres 9 – 11 short, asymmetrical (serrate in 9 – 10), forming a club (Fig. 4 E). Mandibles apically with two vertically arranged teeth (Fig. 4 B). Maxillary palps relatively long; apical palpomere fusiform. Labial palps present; apical palpomere cylindrical. Pronotal disc quadrate; lateral margins straight, denticulate; anterior and posterior angles right- angled; surface with a pair of longitudinal elevated platforms. Hypomera without antennal grooves or impressions. Notosternal sutures not evident, probably absent. Prosternal process raised. Procoxae seemingly countersunk, concealed by prosternal process. Scutellar shield (Fig. 4 C) with anterior margin slightly emarginate; posterior margin rounded. Elytra elongate, parallel-sided; each with five subtle carinae (including sutural carina); scutellar striole present. Mesocoxae longer than wide; separated by approximately width of mesocoxae. Mesocoxal cavities not evident, probably closed laterally. Metacoxae separated by intercoxal process. Tibiae with two spurs. Tarsi 4 - 4 - 4 (Fig. 4 F – H); tarsomeres 1 – 3 similar in form, together shorter than tarsomere 4. Pretarsal claws simple. Abdomen with five ventrites, separated by wide and deeply impressed sutures.	en	Li, Yan-Da, Huang, Di-Ying, Cai, Chen-Yang (2021): An aberrant colydiine-like tenebrionoid beetle from mid-Cretaceous Burmese amber (Coleoptera: Tenebrionoidea: Zopheridae).
