Description of a New Species Hepatozoon quagliattus sp. nov. (Apicomplexa: Adeleorina: Hepatozoidae), infecting the Sleep Snake, Dipsas mikanii (Squamata: Colubridae: Dipsadinae) from Goiás State, Brazil

Description of an intramonocytic haemoparasite, Hepatozoon lainsoni sp. nov. (Apicomplexa: Adeleorina: Hepatozoidae), infecting Ameiva ameiva lizard (Reptilia: Squamata: Teiidae) in northern Brazil

“…With regards to other species from host lizards, H. lainsoni sp. nov. have a similar size range to those of H. caimani Carini, 1909 (12.15 × 4.3 μm 2 ) from the caiman Caiman c. crocodilus (Lainson et al ., 2003 b ), Hepatozoon terzii Sambon and Seligman, 1907 (12.3 × 4.3 μm 2 ) from snake B. constrictor (Paperna and Lainson, 2004 ), Hepatozoon quagliattus Úngari, Netherlands, Silva and O'Dwyer, 2021 (13.58 × 6.22 μm 2 ) from the sleep snake Dipsas mikanii (Úngari et al ., 2021 ) and are smaller than H. musa Borges-Nojosa, Borges-Leite, Maia, Zanchi-Silva, da Rocha Braga and Harris, 2017 (18.9 × 3.8 μm 2 ) from snake Philodryas nattereri (Borges-Nojosa et al ., 2017 ).…”

A 50-year-old redescription: molecular and morphometric characterization of Hepatozoon carinicauda Pessôa and Cavalheiro, 1969 in the brown-banded water snake Helicops angulatus (Linnaeus, 1758)

“…Furthermore, the phylogenetic relationships in our study were quite similar to those obtained by Úngari et al . (2021) and Zechmeisterová et al . (2021), but diverged from the positioning of some lineages in the study by Guitiérrez-Liberato et al .…”

“…The 18S rRNA nuclear marker is very popular, and it is used almost exclusively, in phylogenetic analyses of haemogregarines (Hrazdilová et al ., 2021). It has proven useful for molecular screening of Hepatozoon and species descriptions in snakes (O'Dwyer et al ., 2013; Borges-Nojosa et al ., 2017; Ùngari et al ., 2018, 2021), including in our study. Yet, in recent years the need for the improvement and employment of other genetic markers capable of responding more clearly to the phylogenetic relationships of the group has been discussed (Abdel-Baki et al ., 2014; Maia et al ., 2016; Cook et al ., 2018; Gutiérrez-Liberato et al ., 2021; Hrazdilová et al ., 2021).…”

“…Nineteen sequences retrieved from GenBank (MN833641, MF435047, MF435048, KX880079, MF497763, MF497764, MF497765, MF497766, MF497767, KC342524, MF497769, MF497770, KC342526, MW241134, MW241135, KC342525, MF322538, MF322539, MW591599) and aligned using the MAFFT software package (version 7) (Katoh et al ., 2019), resulting in an alignment of 461 bp, were used to evaluate the genetic diversity of the 18S rRNA gene from Hepatozoon spp. detected in the snake in the present study and in reptiles from previous studies in Brazil (O'Dwyer et al ., 2013, Borges-Nojosa et al ., 2017; Bouer et al ., 2017; Úngari et al ., 2018, 2021; Picelli et al ., 2020). Nucleotide diversity (Pi), haplotype diversity (Hd), number of haplotypes (h), total number of mutations (Eta) and average number of nucleotide differences (k), using DnaSP v5 software (Librado and Rozas, 2009), were calculated.…”

“…40 spp.) in snakes (Pessôa et al ., 1974; Smith, 1996; Úngari et al ., 2018, 2021), only the sequences of 5 species were available to date: Hepatozoon cevapii O'Dwyer et al ., 2013 reported in Crotalus durissus Linnaeus, 1758 (O'Dwyer et al ., 2013) and Thamnodynastes lanei Bailey et al ., 2005 (De Paula et al ., 2021); Hepatozoon cuestensis O'Dwyer et al ., 2013 and Hepatozoon massardii O'Dwyer et al ., 2013 described in C . durissus (O'Dwyer et al ., 2013; Úngari et al ., 2018); Hepatozoon musa Borges-Nojosa et al ., 2017 from Philodryas nattereri (Steindachner, 1870) (Borges-Nojosa et al ., 2017), C. durissus and Epicrates crassus Cope, 1862 (Úngari et al ., 2018); and Hepatozoon quagliattus Úngari et al ., 2021 in Dipsas mikanii (Schlegel, 1837) (Úngari et al ., 2021).…”
