Mitrapus Song & Chen 1976
No full textGenus Mitrapus Song & Chen, 1976 The validity of Mitrapus as a generic level taxon needs testing as it shares multiple character states with Lernanthropus. The females are currently distinguished from female Lernanthropus only by the marked disparity between the lengths of the endopodal and exopodal lobes of leg 4. Given that the relative lengths of the rami of leg 4 can vary between species within both genera, this character is not robust. The males differ but male characters were not used in the phylogenetic analysis of Ho & Do (1985).Published as part of Boxshall, Geoff A., Bernot, James P., Barton, Diane P., Diggles, Ben K., Q-Y, Russell, Atkinson-Coyle, Toby & Hutson, Kate S., 2020, Parasitic copepods of the family Lernanthropidae Kabata, 1979 (Copepoda: Siphonostomatoida) from Australian fishes, with descriptions of seven new species, pp. 1-103 in Zootaxa 4736 (1) on page 79, DOI: 10.11646/zootaxa.4736.1.1, http://zenodo.org/record/366974
Lernanthropidae Kabata 1979
No full textFamily Lernanthropidae In the family Lernanthropidae characters relating to the gross body morphology of the adult female have proven valuable in the discrimination of both generic and species level taxa. At the generic level in particular, the general form of legs 1 to 4 provides important characters, as well as the presence and shape of the dorsal trunk plate(s) on the fourth pedigerous somite, and the form of the egg sacs in the adult female. Older descriptions tended to focus on gross morphology, so characters relating to the details of cephalosomic limbs are often not available. Fortunately, gross morphology is unusually informative in this family, even at the species level, so the taxonomy of lernanthropids is relatively robust. Although some species have been transferred to other genera, 148 of the 167 nominal species formally described in the family remain valid, with only 19 species (11 %) recognized as synonyms. Males of ten species are described here for the first time, including five previously unknown males and five from new species.Published as part of Boxshall, Geoff A., Bernot, James P., Barton, Diane P., Diggles, Ben K., Q-Y, Russell, Atkinson-Coyle, Toby & Hutson, Kate S., 2020, Parasitic copepods of the family Lernanthropidae Kabata, 1979 (Copepoda: Siphonostomatoida) from Australian fishes, with descriptions of seven new species, pp. 1-103 in Zootaxa 4736 (1) on page 7, DOI: 10.11646/zootaxa.4736.1.1, http://zenodo.org/record/366974
Sagum petersi
No full textSagum petersi (van Beneden, 1857) Syn: Lernanthropus petersi van Beneden, 1857 Paralernanthropus petersi (van Beneden, 1857) Pseudolernanthropus petersi (van Beneden, 1857) Material examined: none. Differential diagnosis: Cephalothorax about as long as wide, with evenly convex lateral margins. Trunk irregularly subrectangular, wider than cephalothorax: anterior part of trunk (second and third pedigerous somites) wider than long, produced into tapering posterolateral processes extending about 30% of distance along lateral margins of dorsal trunk plate. Posterior part of trunk covered by broad dorsal trunk plate with rounded hexagonal shape. Dorsal surface of cephalothorax and trunk lacking ornamentation. Urosome formed from fifth pedigerous somite, genital complex and abdomen, all fused. Egg sacs loosely coiled beneath dorsal trunk plate. Paired caudal rami short, tapering towards tip. Leg 2 biramous, with unimerous rami. Leg 3 trilobate, with large, lamellate exopodal lobe orientated horizontally across ventral surface, reaching to posterior end of body, connecting via long posteriorlydirected, flagellum-like middle lobe to smaller rounded inner lobe; flagellate middle lobe extending well beyond posterior margin of dorsal trunk plate. Leg 4 bilobate; with inner and outer lobes long and tapering, distal flagellate parts of both lobes extending well beyond posterior margin of dorsal trunk plate. Body length of ♀ about 5.8 mm (from Kabata, 1979a). Distribution: This species was originally described from Epinephelus fuscoguttatus (Forsskål, 1775) (as Serranus goliath) caught off Mozambique (van Beneden, 1857). It was also listed as occurring on an unidentified host caught off Zaire by Brian (1939), but in the absence of any voucher specimens or description, this record is in need of confirmation. Kabata (1979a) reported S. petersi on Epinephelus lanceolatus (as Promicrops lanceolatus) from Queensland waters. Remarks: This species is not well characterized but the trilobate state of the third leg, with the middle flagellum-like lobe extending beyond the posterior margin of the dorsal trunk plate, as described by Kabata (1979a), is unique within the genus.Published as part of Boxshall, Geoff A., Bernot, James P., Barton, Diane P., Diggles, Ben K., Q-Y, Russell, Atkinson-Coyle, Toby & Hutson, Kate S., 2020, Parasitic copepods of the family Lernanthropidae Kabata, 1979 (Copepoda: Siphonostomatoida) from Australian fishes, with descriptions of seven new species, pp. 1-103 in Zootaxa 4736 (1) on pages 88-89, DOI: 10.11646/zootaxa.4736.1.1, http://zenodo.org/record/366974
Sagum Wilson 1913
No full textGenus Sagum Wilson, 1913 Remarks: The genus Sagum was established by Wilson (1913) to accommodate a new species, S. flagellatum Wilson, 1913, found on the gills of a serranid Epinephelus adscensionis (Osbeck, 1765) caught off Jamaica. The new genus was distinguished from Lernanthropus by “the rostrum and wings of the cephalothorax, by the long endopods of the third legs, and by the lash-like tips of the fourth legs.” The two female syntypes of S. flagellatum lacked egg sacs, so the form of the egg sacs was not included in the original generic diagnosis. In his revision of the North American Dichelesthiidae, Wilson (1922) transferred Lernanthropus angulatus Krøyer, 1863 into Sagum as S. angulatum and gave a revised generic diagnosis which included as a key feature, the possession of coiled egg sacs entirely contained within the space enclosed between the dorsal trunk plate and the third and fourth legs. In their phylogenetic analysis of the lernanthropid genera, Ho & Do (1985) grouped Aethon, Norion and Sagum together on the basis of the possession of coiled egg sacs. They distinguished Aethon by its highly modified second legs and grouped Sagum and Norion by the shared possession of bilobate fourth legs with lobes that are lamellate proximally and flagellate distally. Although used by Wilson (1922) is his original diagnosis of the genus, this latter character is not robust since at least half of Sagum species (see Table 4) have tapering bilobate fourth legs rather than legs with flagellate tips on the exopodal and endopodal lobes. The loss of leg 2 was used to characterize Norion species whereas the form of leg 3, described as “divided into 3 branches; lamelliform or cylindrical”, was used to diagnose the Sagum branch. This latter character is also not robust, applying only to a minority of species. Given the difficulty in using some of these traditional characters, it is clear that the relationships between the currently recognized lernanthropid genera need to be reassessed using a wider range of characters from both sexes.Published as part of Boxshall, Geoff A., Bernot, James P., Barton, Diane P., Diggles, Ben K., Q-Y, Russell, Atkinson-Coyle, Toby & Hutson, Kate S., 2020, Parasitic copepods of the family Lernanthropidae Kabata, 1979 (Copepoda: Siphonostomatoida) from Australian fishes, with descriptions of seven new species, pp. 1-103 in Zootaxa 4736 (1) on page 82, DOI: 10.11646/zootaxa.4736.1.1, http://zenodo.org/record/366974
