In fact my answer is that the very numerous so-called hybrids might be
specimens of a new species born from the hybridization of L. millepeda and L
 lambis .

Peter , my answer to your question is : " Maybe yes . " but I am definitely
not a Strombidae specialist so I will give you this web link which is
interesting : http://www.jaxshells.org/spider2.htm ...and will SHOUT for
help from Gijs Kronenberg and other Strombidae specialist(s) !!! ;-)) Franck

I don't understand: what are the intermediate specimens between Lambis
lambis and Lambis millipeda if they are not hybrids? How can you have
specimens half-way between two species, especially when they are
sympatric, and not refer to them as hybrids. Would their existence not then
call into
question the validity of the two species?

Hello David ,.Well , you did not mean to be offensive :-) . Harpa
articularis do co-exist almost everywhere in the range of H. major . The
range of Harpa davidis partly overlaps with those of H.articularis and H.
major , however it seems there are no hybrids . As I have specialized in
Harpidae ( as well as , recently , in Haliotidae ) my knowledge of possible
hybrids in other families is somewhat limited however real hybridization in
the wild is extremely rare indeed and according to me should be considered
as truly exceptional ( I guess that you read my most recent post to the list
concerning the conditions to meet for hybridization ? ) and not as a rather
common thing such as the case of the intermediary specimens between Lambis
lambis and Lambis millepeda ( which were mentioned in a recent post ) ..
These intermediary specimens are puzzling but my guess is that they should
not be be assigned to hybridization since the populations of millepeda and
lambis really swarm together in the same areas . A strictly personal comment
now : According to me he word "hybrid " is all too often a selling argument
for some seashell dealers and I do not buy this . Franck
