The complete mitogenome of scaly thrush Zoothera aurea (Passeriformes, Turdidae).

The complete mitochondrial genome of scaly thrush Zoothera aurea was obtained by next-generation sequencing. The circular genome was 16,712 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. The overall nucleotide composition was A: 29.67%, T: 23.32%, C: 32.21%, and G: 14.80%. Nine genes were encoded on the light strand, and the remaining 28 genes were encoded on the heavy strand. Most of the PCGs began with the ATG as the start codon, and six kinds of termination codons were used in this mitogenome. This study improves our understanding of the mitogenomic characteristics and its phylogenetic relationships within Turdidae.

Urogonimus turdi (Digenea: Leucochloridiidae) from the White's Thrush, Zoothera aurea, in the Republic of Korea.

Avian trematodes, Urogonimus turdi (Digenea: Leucochloridiidae), were collected from the intestine of wild birds, Zoothera aurea, 2013-2017 in the Daejeon Metropolitan City, Korea. The body was ellipsoidal, attenuated and/or round ends, 1,987-2,120 long and 819-831 µm wide. The oral sucker was subterminal, rounded anteriorly, and 308- 425×351-432 µm in size; the prepharynx and esophagus were almost lacking; pharynx was well-developed, 142- 179×78-170 µm in size; intestine narrow, bifurcating just after pharynx, ascending to the oral sucker before looping posteriorly and terminating near the posterior end; ventral sucker larger, in almost median, 536-673×447-605 µm and approximately 1.5 times larger than oral sucker. A phylogenetic tree constructed with 18S ribosomal RNA showed inter- and intraspecific relationships. Based on these morphological and molecular findings, we report here a U. turdi from White's thrushes in Korea.
