Abstract Revealing the mechanisms underlying community organization has long been a central interest for ecologists and biogeographers.

Potamanthidae belongs to the superfamily Ephemeroidea but has no complete mt genome released in NCBI (except for two unchecked and one partial genome). Since sister clade always been controversial, we sequenced seven genomes of (two species from Rhoenanthus five Potamanthus) order rebuild phylogenetic relationships this study. The divergence time was also investigated by utilizing fossil calibration points because indeterminate origin time. In addition, coreanus Potamanthus luteus are low-temperature environments, aimed explore whether these were under positive selection at level. Amongst 13 PCGs, CGA used as start codon COX1, whereas other genes conformed initiating with an ATN codon. From analysis, UUA (L), AUU (I), UUU (F) had highest usage. Furthermore, DHU arm absent secondary structure S1 all species. By combining PCGs 2 rRNAs, reconstructed relationship within Ephemeroptera. monophyly supported results. + (Ephemeridae Polymitarcyidae) recovered a high prior probability. times traced be 90.44 Mya (95% HPD, 62.80–121.74 Mya), originated approximately 64.77 43.82–88.68 thus belonging late Pliocene Epoch or early Miocene Epoch. data indicated that R. negative ATP8 ND2 evolutionary rate.

Heptageniidae are known for their flat heads and bodies divided into three subfamilies. Despite the extensive diversity within this group considerable efforts made to understand evolutionary history, internal classifications origin time of remains controversial. In study, we newly sequenced 17 complete mitogenomes reconstruct phylogenetic positions family. Because ambiguous origin, our study also estimated divergence based on five fossil calibration points. The results BI ML trees all highly supported monophyly relationship Rhithrogeninae + (Ecdyonurinae Heptageniinae) was recovered. showed that originated from 164.38 Mya (95% HPD, 150.23–181.53 Mya) in mid-Jurassic, 95.54 73.86–120.19 mid-Cretaceous. Ecdyonurinae Heptageniinae began diverge at 90.08 68.81–113.16 middle Cretaceous. After morphological identification, analysis mitogenome’s composition, genetic distance calculation, analysis, suggest two different populations Epeorus montanus collected Aksu, Xinjiang Uygur Autonomous Region (40°16′ N, 80°26′ E) Xinyuan, (43°20′ 83°43′ China cryptic species E. montanus, but further detailed information characteristics is needed fully identify them.
