“…However, the systematics of the families Camaenidae, Helicidae and Bradybaenidae are complicated and not fully resolved. Systematic and phylogenetic studies based on analyses of morphological versus molecular markers have produced inconsistent results (Scott 1996; Cuezzo 2003; Wade et al 2007; Hirano et al 2014). A final assessment of the systematic relationships of the three families is pending requiring a more complete taxon sampling.…”

The complete mitochondrial (mt) genome of the snail Camaena cicatricosa (Müller, 1774) has been sequenced and annotated in this study. The entire circular genome is 13,843 bp in size and represents the first camaenid mt genome, with content of 31.9%A, 37.9%T, 13.5%C and 16.7%G. Gene content, codon usage and base organization show similarity to a great extent to the sequenced mt genome from Stylommatophora, whereas, gene order is different from them, especially the positions of tRNACys, tRNAPhe, COII, tRNAAsp, tRNAGly, tRNAHis and tRNATrp. All protein coding genes use standard initiation codons ATN except for COII with GTG as start signal. Conventional stop codons TAA and TAG have been assigned to all protein coding genes. All tRNA genes possess the typical clover leaf structure, but the TψC arm of tRNAAsp and dihydrouridine arm of tRNASer(AGN) only form a simple loop. Shorter intergenic spacers have been found in this mt genome. Phylogenetic study based on protein coding genes shows close relationship of Camaenidae and Bradybaenidae. The presented phylogeny is consistent with the monophyly of Stylommatophora.

The land snail Cernuella virgata (da Costa, 1778) is widely considered as a pest to be quarantined in most countries. In this study, the complete mitochondrial genome of Cernuella virgata is published. The mitochondrial genome has a length of 14,147 bp a DNA base composition of 29.07% A, 36.88% T, 15.59% C and 18.46% G, encoding 13 (PCGs)protein-coding genes , 22 (tRNA)transfer RNA genes and two (rRNA)ribosomal RNA genes. The complete nucleotide composition was biased toward adenine and thymine, A+T accounting for 69.80%. Nine PCGs and 14 tRNA genes are encoded on the J strand, and the other four PCGs and eight tRNA genes are encoded on the N strand. The genome also includes 16 intergenic spacers. All PCGs start strictly with ATN, and have conventional stop codons (TAA and TAG). All tRNAs fold into the classic cloverleaf structure, except tRNAArg, tRNASer(UCN), tRNASer(AGN) and tRNAPro. The first three lack the dihydrouridine arm while the last lacks the TψC arm. There are 502 bp long noncoding regions and 418bp long gene overlaps in the whole mitochondrial genome, accounting for 3.54% and 2.95% of the total length respectively. Phylogenetic analyses based on the sequences of the protein coding genes revealed a sister group relationship between the Hygromiidae and the Helicidae.

“…Due to the substantial incongruence among the morphology, taxonomy and molecular phylogeny of the Bradybaenidae, the classification of this family is still ambiguous, especially among the genus Aegista (Hirano et al, 2014). Here, we first determined the complete mitochondrial genome of A. aubryana, providing useful information for further studies of taxonomy and phylogenetic analysis in bradybaenid snails.…”

Aegista aubryana is an endemic land snail in China. The complete mitochondrial genome of A. aubryana was first determined using long PCR reactions and primer walking method (accession number KT192071). The genome has a length of 14 238 bp, containing 37 typical mitochondrial genes (13 protein-coding genes, 22 tRNA genes and 2 rRNA genes). The base composition of the whole heavy strand is A 31.32%, T 37.86%, C 14.46% and G 16.36%. The results of phylogenetic analyses showed that the A. aubryana is most closely related to Mastigeulota kiangsinensis. This new complete mitochondrial genome can be the basic data for further studies on mitogenome comparison, molecular taxonomy and phylogenetic analyses in bradybaenid snails and Molluscs at large.
