Distribution.
West Indies (

,
Jamaica
), Central America (
Costa Rica
,
Guatemala
,
Honduras
,
Panama
), South America (
Colombia
,
Trinidad
,
Venezuela
).
Hosts.
Dactylopiidae
:
Dactylopius

;

:
Diaspis boisduvalii
Signoret.
Remarks.
In the West Indies and
Trinidad
, specimens were collected in urban and natural areas, often associated with
Stachytarpheta
sp. (Verbenaceae)
. In Central and South America, specimens were collected on cultivated fruit crops such as papaya (
Carica papaya
L.), cassava (
Manihot esculenta
Crantz
) and banana (
Musa
sp.
), undoubtedly feeding on the associated scale insects. Interestingly, this species has been collected in various traps, including flight intercept yellow pan traps in coastal desert scrub habitats of Cura
çao
, black light/mercury vapor traps in
Guatemala
and castor oil traps in
Venezuela
. A series of over
50 specimens
were collected in
Honduras
feeding on
Dactylopius
sp. (Datcylopiidae)
, infesting
Opuntia
sp. (Cactaceae)
.
Taxonomy.
Cybocephalus caribaeus
T. R. Smith is treated herein as a synonym of
C. geoffreysmithi
. A large series of this species from
Honduras
was found after the original descriptions of both species were published (
Smith and Cave 2007a
). Additional specimens from
Guatemala
and
Panama
were also examined and compared to the
holotypes
of both species. After a detailed examination of all material, it is clear that these two species are, in fact, one. There is some natural variation in the male genitalia that led to the original separation of the two species; however, the basic structure of the male genitalia is identical, and no differences can be found in the shape of the legs and antennae. The most distinctive characteristic of this species is the notched lateral margins of the median lobe (
Fig. 75, 76
). This characteristic is not found in any other species of
Cybocephalus
in the Western Hemisphere. The apical margin of the basal plate (originally used to separate the two species) varies from rounded, slightly flattened, or slightly emarginate. However, considering that all other morphological aspects of the two are identical, this is regarded as intraspecific variation. Based on these characters,
C. caribaeus
should be treated as a synonym of
C. geoffreysmithi
.
