Forcipomyia Meigen, 1818, is the second-largest genus of the family Ceratopogonidae, having medico veterinary and agricultural importance. A few mitogenomes of Ceratopogonidae have previously been available. Here, we aimed to characterize the whole mitogenome of Forcipomyia pulchrithorax Edwards, 1924, collected from Central Anatolia Region of the Türkiye using NGS to contribute to the genetic diversity within this family. The mitogenome of F. pulchrithorax (OR666457) consisted of a circular DNA molecule spanning 15,930 bp and containing 72.7% AT content. It includes 13 proteincoding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and 1 control region. All PCGs exhibited typical ATN start codons and followed the conventional TAN stop codons, except COX1, COX2, COX3, ND1, and ND5, which ended with incomplete codons. The 22 tRNA genes demonstrated the ability to form a cloverleaf structure, except tRNA-Ser1, which lacked DHU arm, similar to most insect mitogenomes. The ML phylogenetic analyses clearly delineated the species of Culicomorpha into well supported monophyletic clades. Forcipomyia pulchrithorax was clustered with the Ceratopogonidae species constituting an outer taxon among the Culicomorpha. The comprehensive mitogenome of F. pulchrithorax will be valuable for future studies focused on the phylogenetic characterization and diversity of Ceratopogonidae within the Culicomorpha.

• Mitogenomes of Turkish tree squirrels were successfully sequenced, assembled and annotated for the first time, including 19 for S. anomalus (from 16,505 bp to 16,510 bp) and one for S. vulgaris (16,511 bp). • Based on mitogenomic dataset for phylogeny of Sciurinae, phylogenetic analyses did not support monophyly of Sciurus and proposed that S. anomalus , the most basal taxa in the Sciurini tribe, had at least five mitogenome lineages, which were also supported by network analysis. • The current study proposed that the use of mitogenomic data for reconstructing the phylogeny of Turkey's Sciurus holds an important value for revealing evolutionary relationships. The genus Sciurus , a member of the family Sciuridae, is widely distributed in the Holarctic region. To better understand mitogenomic characteristics and to reveal internal phylogenetic relationships of the genus, 20 complete mitogenomes of Turkish tree squirrels were successfully sequenced for the first time, including 19 for S. anomalus (from 16,505 bp to 16,510 bp) and one for S. vulgaris (16,511 bp). The mitogenomes of two species were AT-biased. All tRNAs for two species displayed a typical clover-leaf structure, except for tRNA Ser(AGY). The tRNA Serine1 (S1)-GCT structure lacked the dihydrouridine (DHU) loop and stem. Based on mitogenomic dataset for phylogeny of Sciurinae, phylogenetic analyses (Bayesian Inference and Maximum Likelihood) did not support monophyly of Sciurus and proposed that S. anomalus , the most basal taxa in the Sciurini tribe, had at least five mitogenome lineages, which were also supported by network analysis. The dissimilarities among the five lineages of S. anomalus ranged from 0.0042 (0.42%) to 0.0062 (0.62%) using K2P sequence pairwise distances. In addition to this mitogenomic analysis result, phylogenetic analyses using the CYTB + D-loop dataset proposed the existence of at least nine lineages for S. anomalus , which was different than those of the previous studies. The current study proposed that the use of mitogenomic data for reconstructing the phylogeny of Turkey's Sciurus holds an important value for revealing evolutionary relationships.
