Atopocelyphus is a monotypic genus of beetle flies (family Celyphidae) and is the only genus of this family known to occur in the Neotropical region.[2] The genus was described by Stephen D. Gaimari in 2017.[3]
The genus is represented by the single species Atopocelyphus ruficollis (Macquart, 1844).[2] It has been recorded in French Guiana and in the state of Amapá, Brazil.[2] Specimens have been collected in well-preserved forest environments near small streams, suggesting that adults may be active throughout the year.[2]
While specific morphological traits of Atopocelyphus are documented in scientific literature, the available images from the TreeOfLife-200M dataset are of preserved museum specimens, which limits the observation of live coloration and soft-tissue structures.[1]
The terminalia of A. ruficollis provide diagnostic characters. In males, the epandrium is subquadrate and forms a complete ring, and the phallus contains six thin ejaculatory ducts.[2] Females possess an enlarged, convex, canoe-shaped sternite 8 and three brown, globular spermathecae.[2] The eggs are ovoid, approximately 0.88 mm long, and feature a distinct anterior tubercle and a posterior knob-like swelling.[2]
