Dear colleagues and friends
It is my pleasure to share with you another step of my thesis on the phylogeny
of the Caenogastropoda based on detailed morphology.
This time are the Cypraeoidea, that I have published as a book as below:

SIMONE, L. R. L., 2004. Morphology and phylogeny of the Cypraeoidea (Mollusca,
Caenogastropoda). 1. ed. Rio de Janeiro: Papel Virtual. v. 1. 185p.

Its website, unfortunately still in Portuguese, is the following:

The abstract of the paper is:

With the intention of searching the monophyly and the ground plan of the
Cypraeoidea, including Lamellarioidea, a sample of 28 species of the former and
5 of the latter were studied in detailed comparative morphology. The species are
the following: 1) Cypraeidae: Macrocypraea zebra (Linné) (from Brazil); M.
cervinetta (Kiener) (from Panama, Pacific); Erosaria acicularis (Gmelin) (W.
Atlantic); E. spurca (Linné) (N. Atlantic and Mediterranean); Luria cinerea
(Gmelin) (NE Brazil); Cypraea tigris Linné (SW Pacific) (type species); Lyncina
lynx (Linné) (SW Pacific); Monetaria moneta (Linné) (W. Pacific); M. annulus
(Linné) (W. Pacific); Ravitrona caputserpentis (Linné) (Hawaii); Muracypraea
mus (Linné) (Venezuela); Pseudozonaria arabicula (Linné) (Ecuador); P. robertsi
(Hidalgo) (Ecuador); 2) Ovulidae: Cyphoma signatum Pilsbry & McGinty (W.
Atlantic); C. gibbosum (Linné) (Caribbean); Pseudocyphoma intermedium (Sowerby)
(Brazil); Ovula ovum (Linné) (W. Pacific); Calpurnus verrucosus (Linné)
(Philippines); Simnialena uniplicata (Sowerby) (SE Brazil); Cymbula acicularis
(Lamarck) (Caribbean); Jenneria pustulata (Lightfoot) (Panama, Pacific); 3)
Triviidae: Niveria pediculus (Linné) (Brazil); Trivirostra oryza (Lamarck)
(Australia); 4) Eratoidae: Hespererato maugeriae (Gray) (E. USA); 5)
Pediculariidae: Pedicularia sp1 (Tonga); P. californica Newcomb (California,
USA); P. decussata (Gould) (Bahamas); P. sp2 (Australia); 6) Lamelariidae:
Lamellaria branca n. sp. (SE Brazil); L. mopsicolor Marcus (SE Brazil); L.
patagonica E.A. Smith (S. Argentina); Velutina velutina Müller (W. USA);
Velutina sp (Massachusetts, USA). Each species is described with a formal
taxonomical treatment. A total of 132 characters were searched in 322 states.
They were analyzed under formal cladistic methodology, resulting in a single
most parsimonious tree, with the following indices: length: 281, CI: 68, RI:
89. The tree is the following: ((Velutina velutina (Lamellaria patagonica (L.
mopsicolor – L. branca))) ((Pedicularia sp1 (P. sp2 (P. decussata – P.
californica))) (Hespererato maugeriae ((Niveria pediculus – Trivirostra oryza)
((Jenneria pustulata ((Simnialena uniplicata – Cymbula acicularis) (Ovula ovum
(Calpurnus verrucosus (Pseudocyphoma intermedium (Cyphoma signatum – C.
gibbosum)))))) (Ravitrona caputserpentis ((Pseudozonaria robertsi – M.
arabicula) ((Luria cinerea – Lyncina lynx) ((Cypraea tigris (Macrocypraea zebra
– M. cervinetta)) ((Erosaria acicularis – E. spurca) (Monetaria moneta – M.
annulus))))))))))). The monophyly of the superfamily Cypraeoidea is confirmed,
supported by 34 morphological synapomorphies; the lamellarioideans can be
regarded as part of the taxon. The species presently considered Eratoidae
resulted as 2 successive branches, then paraphyletic; the separation into 2
families is necessary (Eratoidae and Triviidae). The Cypraeoidea groups the
following monophyletic families, respectively distributed along the cladogram:
Lamellariidae, Pediculariidae, Eratoidae, Triviidae, Ovulidae and Cypraeidae,
being the 2 last ones sister taxa. As secondary results are: 1) the
confirmation of the specific separation between Erosaria spurca and E
acicularis; 2) the description of a new species of Lamellaria (L. branca); 3)
the base for specific and supra-specific future revision of the taxa such as
families and genera 4) some new synonyms (Luria cinerea brasiliensis Lorenz &
Hubert, 1993 = L. cinerea; Pseudocyphoma christahemmenae Fehse, 1997, Cyphoma
guerrinii and Pseudocyphoma rosembergi both Fehse, 2001, = P. intermedium;
Simnialena ilhabelaensis Fehse, 2001 = S. uniplicata).

I hope you enjoy it!
With my best whishes, Luiz
