Molecular Phylogenetic Position of the New Zealand Sentinel Crab, Macrophthalmus (hemiplax) Hirtipes (jacquinot, in Hombron

چکیده
The systematic position of the New Zealand sentinel crab Macrophthalmus (Hemiplax) hirtipes (Jacquinot, in Hombron & Jacquinot, 1846) has been questioned because the zoeal morphology is incongruent with that of other species assigned to the genus. A molecular phylogeny based on the mitochondrial large subunit (16S) rRNA gene indicates M. hirtipes is distinct from other macrophthalmid species, and found to be more closely related to the New Zealand varunids Austrohelice crassa, Hemigrapsus crenulatus, and Hemigrapsus sexdentatus. This indicates that the genus Macrophthalmus Desmarest, 1823 needs to be revised.

Behavioural and Molecular Evidence for the Systematic Position of Macrophthalmus (hemiplax) Hirtipes Hombron & Jacquinot, 1846, with Comments on Macrophthalmine Subgenera (decapoda, Brachyura, Macrophthalmidae)
The analysis of 16s rRNA data from the New Zealand sentinel crab, Macrophthalmus (Hemiplax) hirtipes (Jacquinot & Hombron, 1846) (Macrophthalminae: Macrophthalmidae) shows that it is the most basal species in the genus Macrophthalmus, and behavioural trait mapping suggests that ancestral behaviours included extended cheliped fighting. Other behaviour found in some sentinel crabs, such as allocl...
متن کاملLarval spirurida (Nematoda) from the crab Macrophthalmus hirtipes in New Zealand.
Previously undescribed third-stage larvae of two species of Spirurida were found in the haemocoel of the stalk-eyed mud crab Macrophthalmus hirtipes (Heller) (Ocypodidae) in New Zealand. Examinations by light and scanning electron microscopy showed that the larger larvae (about 7 mm long) belonged to a species of Ascarophis van Beneden, 1871 (Cystidicolidae), the genus including parasites of fi...
متن کاملField evidence of the impact of two acanthocephalan parasites on the mortality of three species of New Zealand shore crabs (Brachyura)
The effects of the acanthocephalan parasites Profilicollis antarcticus and P. novaezelandensis on the fecundity and mortality of three species of shore crab (Macrophthalmus hirtipes, Hemigrapsus edwardsi and H. crenulatus) are examined. The number of eggs produced by female crabs was strongly correlated (all P<0.05) with carapace width; parasite load was not a significant determinant of female ...
متن کاملEffect of acanthocephalan parasites on hiding behaviour in two species of shore crabs.
The effect of acanthocephalan parasites (Profilicollis spp.) on the hiding behaviour during low tide of two species of shore crabs (intermediate hosts), Macrophthalmus hirtipes (Brachyura: Ocypodidae) and Hemigrapsus crenulatus (Brachyura: Grapsidae), was examined at Blueskin Bay, South Island, New Zealand. Exposed M. hirtipes were found to have significantly higher infection levels than did hi...

We quantified the clonal diversity of the New Zealand marine trematode Maritrema novaezealandensis (n = 1250) within Zeacumantus subcarinatus snail (n = 25) and Macrophthalmus hirtipes crab (n = 25) intermediate hosts using four to six microsatellite loci, and investigated the potential biological and physical factors responsible for the observed genetic patterns. Individual snails harboured on...
