Diagnosis.
Laccophilus gentilis suavis
is superficially very similar to
L. ovatus zapotecus
. However,
L. gentilis suavis
may be distinguished by the weak metacoxal file and aedeagus with an enlarged and rounded apex in lateral view (
Fig. 9A
) whereas
L. ovatus zapotecus
has the aedeagus with a subtriangular apex in lateral view (Fig.
273 in
Zimmerman 1970
).
Distribution.
This species is known from
Mexico
through Central America to
Panama
and the West Indies (
Zimmerman 1970
). In
Cuba
,
L. gentilis suavis
has been recorded from the central and eastern parts of the country (
Fig. 15
).
Laccophilus gentilis gentilis
LeConte
occurs along the Gulf Coast of the
United States
.
Ecology.
Laccophilus gentilis suavis
has been collected in the lowlands in permanent lagoons with abundant aquatic vegetation, muddy sediment, and turbid water. According to
Zimmerman (1970)
,
L. gentilis suavis
occurs in coastal plains up to an elevation of
5,000 feet
(ca.
1,524 m
).
Comments.
Laccophilus gentilis suavis
has the metacoxal file weakly impressed, but this file may be lacking in some specimens from North America (
Zimmerman 1970
;
Spangler 1981
).
