“…We regard the presence of two columns of denticles and flanking the mouth as the marquee feature that differentiates Nomasanguinicola from all other blood fluke genera. Other aporocotylids have minute, straight spines typically arranged in concentric rows distributing anterior to the mouth (Meade and Pratt 1965, schell 1974, guidelli et al 2002, Bullard 2012; however, those spines should not be confused with the denticles described herein and diagnostic for Nomasanguinicola. Moreover, we doubt that the denticles of Nomasanguinicola and the concentric, minute spines of aporocotylids are homologous.…”

“…data), we observed minute (< 5 μm in total length), putative spines on the surface of the oral sucker. Although spinous anterior suckers are well-documented among fish blood flukes (Aporocotylidae) (Bullard et al 2008, McVay et al 2011, Bullard 2012, 2013, Truong and Bullard 2013, this is the first report of spines associated with the oral sucker of a TBF. Although materials at our disposal herein precluded an ultrastructural study of these minute spines, a follow-up study treating them is planned once additional specimens have been collected and prepared.…”

The new species is most easily differentiated from its congeners by the combination of having caeca that extend far beyond the genitalia, intercaecal genitalia positioned in the middle portion of the body, a testicular column that nearly abuts the caecal bifurcation, a cirrus sac positioned between the testes and ovary, a massive Mehlis' gland, an elongate, longitudinal metraterm that extends anteriad beyond the level of the ovary, a pre-ovarian genital pore, and a prominent, intercaecal Manter's organ. The specimens of S. cf. scripta differed from the holotype and published descriptions of Spirorchis scripta Stunkard, 1923 by several subtle morphological features, perhaps comprising intraspecific variation, but collectively warranted a detailed description herein. Based on examinations of the aforementioned specimens plus the holotype, paratypes and vouchers of morphologically-similar congeners, Spirorchis MacCallum, 1918 is emended to include the presence of oral sucker spines, a pharynx, lateral oesophageal diverticula ('plicate organ') and a median oesophageal diverticulum ('oeseophageal pouch'). Phylogenetic analysis of the nuclear large subunit rDNA (28S) recovered S. collinsi sister to Spirorchis picta Stunkard, 1923, > 99% similarity between S. cf. scripta and S. scripta, and a monophyletic Spirorchis MacCallum, 1918. No blood fluke infection has been reported previously from these drainages, Alabama, or this turtle species. This is the first new species of Spirorchis to be described from North America in 26 years. Keywords: taxonomy, Spirorchiidae, Spirhapalum, 28S phylogeny, BaracktremaTwenty two species of turtle blood flukes (TBF) ranging in North America are assigned to Spirorchis MacCallum, 1918, Hapalorhynchus Stunkard, 1922, Unicaecum Stunkard, 1925 and Vasotrema Stunkard, 1928. Collectively, they infect 16 species of freshwater turtles: four infect snapping turtles (Chelydridae), ten infect pond turtles (Emydidae), three infect mud/musk turtles (Kinosternidae) and five infect softshell turtles (Trionychidae) (see Platt 1993, 2002, Smith 1997a,b, Orélis-Ribeiro et al. 2014. One third (29 of 86; 34%) of the freshwater turtle species in North America range in rivers and lakes of Alabama (van Dijk et al. 2014, Guyer et al. 2015 and three of the 13 (23%) species of planorbid snails that range in Alabama (Johnson et al. 2013) are known to shed cercariae of Spirorchis spp. elsewhere (Wall 1939, 1940, 1941a,b, Pieper 1953, Goodchild and Kirk 1960, Holliman and Fisher 1968, Holliman et al. 1971). Yet, no TBF infection has been reported from a turtle or snail in Alabama and few (11 of 29; 38%) turtles that occur there are known as TBF hosts elsewhere (Smith 1997a,b).Parasitological examinations of two chicken turtles, Deirochelys reticularia (Latreille in Sonnini et Latreille) from Alabama rivers revealed infections by a new species of Spirorchis and Spirorchis cf. scripta.

“…Cardicola continues to exhibit a remarkable rate of discovery, with 24 new species attributed to this genus since 2000 (Yong et al, 2018; WoRMS Editorial Board, 2018). This is likely a consequence of multiple factors, including the circulatory system historically being overlooked in routine fish dissections (Cribb and Bray, 2011), increased dedicated taxonomic research effort in the northern (e.g., Bullard and Overstreet, 2004; Bullard et al, 2012; Bullard, 2010, 2013) and southern hemispheres (e.g., Nolan and Cribb, 2006, 2014; Yong et al, 2016, 2018), and importance in aquaculture (e.g., Cribb et al, 2000; Ogawa et al, 2010). Recently, Nolan et al (2014) predicted that continued discovery of new Cardicola species would likely reveal a series of radiations in association with particular fish taxa, as well as evidence of host-switching.…”

We describe the first known blood fluke from a marine mammal, the dugong, Dugong dugon (Sirenia: Dugongidae), which represents a new species of aporocotylid, Cardicola dhangali n. sp. (Digenea: Aporocotylidae). Eggs presumed to be of blood flukes have been previously reported from dugongs. This exciting discovery raises questions regarding evolution and host-switching in the Aporocotylidae, which prior to this study were only known to infect actinopterygian and chondrichthyan fishes. The new species has male and female genital pores opening on the right side of the body, with the male genital pore opening posterior to the entire reproductive system and the testis is extra-caecal. The uterus is highly convoluted, and the ovary is irregularly lobate. These features, together with the size and number of the tegumental spines per row, easily distinguish the new species from the most similar congeners Cardicola aurata Holzer et al., 2008, Cardicola chaetodontis Yamaguti, 1970, Cardicola currani Bullard and Overstreet, 2004, Cardicola forsteri Cribb et al., 2000, C. jiingurru Yong et al., 2016, and Cardicola palmeri Bullard and Overstreet, 2004, all of which infect actinopterygian fishes. Given that Cardicola is the most diverse and least host-specific of the marine aporoctoylid genera, it seems credible that a successful host-switch has occurred from an actinopterygian to D. dugon . Further sampling of sirenians and other marine mammals is warranted to gain a more comprehensive understanding of the evolutionary biology and biodiversity of the blood flukes (superfamily Schistosomatoidea Stiles and Hassall, 1898), but presents a substantial challenge with respect to their conservation status and large size.
