The caddis-flies (Trichoptera) of
Cuba and of Isla de Pinos: a synthesis

the fauna of Even a few years ago, caddis-fly Cuba remained very
poorly known. The situation notably improved, especially following
the of collections made the either study throughout Island, by my-
self, or by Cuban entomologists (Botosaneanu & Sykora 1973,
Botosaneanu 1977, Botosaneanuin press).
somewhat less and At present, than 80 species subspecies are known from Cuba (2 Rhyacophilidae Hydrobiosinae, 8 Glossosoma-
tidae Protoptilinae, 6 Philopotamidae, 1 Psychomyiidae Xypho-
centroninae, 6 Polycentropodidae, 6 Hydropsychidae Hydropsy-
chinae and 3 Macronematinae, 31 Hydroptilidae, 3 Leptoceridae, 2
Odontoceridae, 4 Calamoceratidae, 5 Helicopsychidae). But we can
expect some 10 additional species to be discovered. These figures
when those obtained for the are reasonably high compared to other antillean Islands (see especially Flint 1964, 1968a, 1968b): for
Jamaica and Puerto Rico, both well investigated and smaller than
39 and Cuba, the figures are 32 respectively; only 27 species were
quoted from Hispaniola (Haiti, certainly having a rich fauna, is still very poorly known); 44 species have been reported on the whole for the Lesser Antilles. The percentage of endemical taxa is remark-
ably high: 61 from the 76 total. These are species of Atopsyche

tions carried on its caddis-fly fauna allow to distinguish a lot of

the limits of one of these natural regions. Selected are here a few
examples offered by the Cuban fauna for illustrating these 4 dif-
ferent Occ. cases (abbreviations: C. = Cuba; = Occidental region;
Oriental = Central I.P. = Isla de Or. = region; Centr. region;
Pinos; see Fig. 10).

few but rather are relatively phyletically varied. The Polycentropo-
didae are rather well represented (2 Antillopsyche and 3 Polycentro-
pus).
One of the remarkable the most positive features is presence of a
group of 4 nearly related Hydropsyche (these are - together with 2
species from Hispaniola - the only representatives of the genus in
the the otherwise absent from South Antilles, genus being America).

O. islenia Bots., or the 3 species of Neotrichia (alata Flint, pequenita

"lustre" is confered to the Cuban fauna by the Helicopsyche:

The affinities between the Cuban fauna and that of each of the other islands of the Greater Antilles, are approximatively of the
same order. 36
- divided Cuba J. The cuban geographer NUNEZ-JIMENEZ (1972)
in 5 "natural regions": Occidental, Central, Camagiiey-Maniabon,
Oriental, and Isla de Pinos. This division is certainly warranted,
the fauna. the as shown also by caddisfly With the exception of
known Camagiiey-Maniabon region (almost no caddis, and certainly
each a fauna a number very poor fauna), region possesses including of characteristic elements. The richest and best characterized region
known is the Oriental one: 32-33 taxa exclusively from this region.
The 8-9 5 Occidental region follows at a good distance, with taxa.
Isla taxa are exclusively known from the Central region, and 2 from
de Pinos. All this very well reflects the geomorphological, geologi-
cal, and hydrological peculiarities of the different regions.
Rather frequently, a species inhabits Occ. + Centr. (4 cases), Occ.
I.P. 4 -)- (3 cases), or these 3 regions together (2 cases); there are
species inhabiting Or. -f- Centr.; several species are widely distri-
buted the and the be consi- throughout Island, following ones may
dered as being the most frequent and widely distributed: Chimarra
Bks. (Curgia) pulchra (Hag.), Smicridea comma (with some doubt!
further see below), Neotrichia iridescens Flint, Nectopsyche cubana
(Bks.), Oecetis inconspicua (Walk.). To come up again to the vica- riants, this time between different natural regions, the following
examples will be quoted: Cariboptila soltera Bots. (Occ.) - C. guaji-
Bots. and Bots. Macronema Bks. ra C. poquita (Or.); gundlachi

course (competitive exclusion?). 37
TAXONOMICAL AND OTHER PROBLEMS
I have provisionnally reported most of theSmicridea taken in Cuba
but I forced that to the species comma Bks.; am to say practically
each locality, or group of localities, has given a slightly different
morphological type, so that the specific determination remains
doubtful, especially in the absence of dry specimens; Dr. O. S. FLINT,
find the solution of this the other jr., proposes to puzzle. On side, a
quite similar problem is that of a lot of Helicopsyche "populations"
in should be attached the “haitiensis- which my opinion to group”
Prof. H. H. Ross who is Cuban Heli- (according to studying my
copsyche: "They are definitely the most puzzling collections of
Helicopsyche I have ever studied").
The in rather Cuban of androco- occurrence many Trichoptera nial formations and of specialized hairs should also be emphasized.
For instance, Cubanoptila muybonita Bots. is, as far as I know, the
only described Protoptilinae to have in the fore wings of the <$ a
wide zone covered with small, highly specialized hairs; Ochrotri-
chia caramba Bots., and O. villarenia Bots. are probably the only
in - representatives of the genus to have scales the fore and hind
wings of the Oecetis maspeluda Bots. is readily distinguished by
the of fine black hairs in the well groups hind wings (<£, $) as as by
the occurrence ($) of a very long penicillus of black androconial
hairs inserted at the base of the anterior femur; the Helicop-

area covered with black scales; Helicopsyche comosa Kings, and a
in the of new, not yet described, species, are certainly unique limits
the the dense hairs their genus, by covering of long on gonopods.
GEOGRAPHICAL DISTRIBUTION (SEE TABLE)
the The close analysis of geographical distribution on one side, of the "sister relationships" on the other side, leads to the following conclusions (see also Ross 1967 and FLINT 1977).
— number of bear a) A great species a quite distinct "Antillean
which stamp", belonging to genera or to species groups are strictly 38
all Antillean (or even Cuban). Some examples: the Protoptilinae,
Chimarra (C.) cubanorum Bots. and C. (C.) garciai Bots., the two
Antillopsyche, Polycentropus nigriceps Bks. and P. turquino Bots,
Alisotrichia fundorai (Bots. & Syk.), A. chiquitica Bots. and A.
Ochrotrichia insularis and O. islenia alayoana Bots., ayaya Bots.
Bots., Helicopsyche granpiedrana Bots. & Syk.
b) -If the somewhat more remote affinities of the taxa are also considered, we find that, in many instances, the taxa show more or less distinct relationships with elements of continental Central Ame- rica and/or of S (especially SE) North America (if there is not simply identity). Some examples: Polycentropus criollo Bots., all the
Hydropsyche, Leucotrichia cf. tubifex Flint, Ochrotrichia caramba
Bots. and O. villarenia Bots., Orthotrichia americana Bks. and O. cristata Mort. Loxotrichia glasa Ross, the 5 Oxyethira, the 4 Hydrop- tila, all the Helicopsyche excepting granpiedrana.
- On the the c) contrary, taxa certainly or possibly belonging to trends of South American origin, are extremely seldom, but never- theless highly interesting. Examples: Atopsyche cubana Flint and
A. vinai Syk. & Bots., Chimarra (Curgia) pulchra (Hag.) and C.
(Curgia) alayoi Bots., C. (C.) guapa Bots. It is now a demonstrated fact that the trichopteran fauna of Cuba does not belong to the
"faunal circle" represented in the Lesser Antilles northern
South America + southern continentalCentral America, but to that including the Greater Antilles + southern North America + north- ern continental Central America.
Much interest is being now displayed for the Mexico Bay-Carib-
bean Sea much and areas, including geological, geomorphological, paleogeographical research, the results of these studies having im- plications on the problem of the origin and evolution of the fauna inhabiting the lands of the area. More and more publications are accumulating on this item (see, for instance, the comprehensive
of ROSEN with conclusions often di- paper 1975), being extremely

attachment fanatical to a certain theory. What is now of outmost importance, is to obtain the most possible information from the 39
many-sided investigation of as varied groups as possible. The re-
of "excellent" sults obtained up to the present from the study an
like the entitle to consider the most group caddisflies, us as being plausible the following scheme for the origin and evolution of the
Greater Antilles and of their faunas: ejection in the direction of the
Atlantic of a "proto-Antillean kernel" starting from continental
Central America; fragmentation of this "kernel"; repeated contacts between its different fragments, as well as between them - and es-

tion, at certain moments, of lineages starting from northern South
America, via the stepping stones represented by the Lesser Antilles.
isolation Dispersal (+ dispersion) on one side, geographic on the other side, played equally significant parts in the building up of the
present caddisfly fauna.
ECOLOGY (see Plates I-IV)
As far as the ecology is concerned, the following ideas should be
considered only as "landmarks". The mountains of the Oriental region, with their dense hydrographic network, and still protected
by a primary or secondary forest cover, are inhabited by the richest and the most diversified fauna. Unfortunately, almost nothing is
about the known Trichoptera of an altitudinal zone comprised be-
tween 1000 and 2000 which is often m (the highest elevation) prac-
tically inaccessible. The Oriental mountains are followed by those of the Occidental region, then by Sierra Escambray in the Central one. Theremaining areas of Cuba have a considerably impoverished fauna, with region Camagiiey-Maniabon being the poorest. Indus- trial water polution is almost inexistent, but the deforestation has

Cienaga de Zapata, are still poorly known). Most of the species are
