Lestes forficula
Rambur
is known from the surrounding countries French Guiana (
Selys, 1862
;
Machet, 1989
as
Lestes forficulus
),
Brazil (
Selys, 1862
) and Venezuela (
Racenis, 1958
;
De Marmels, 1990
).
A male of this species has also been collected by me during a trip through Brazil (State of Bahia, Santo Amoro, 31.vii.1992,1
♂
)
. It is highly probable that the species occurs in Surinam.
Lestes forficula
is somewhat similar to the newly described species
Lestes basidens
,
but the former is characterized by having the inner side of the male superior caudal appendages with a median dilatation and in having the pectoral colour pattern only with a pair of metepimeral spots. In this respect the pectoral colour pattern of
Lestes forficula
resembles that of
Lestes bipupillatus
Calvert, 1909
, which seems to be its nearest ally. Some specimens of
Lestes forficula
have a weakly developed mid-ventral posterior metasternal spot (fig. 3).
I add illustrations of some specifically important details of the male and female of
Lestes forficula
.
The dimensions of the specimens studied by me are: Male.— Total length ca. 37; abdomen 29-31; hind wing 19-20; costal edge of stigma in fore wing 1.2 1.4. Female.— Total length ca. 37; abdomen 29-30; hind wing 21-22; costal edge of stigma in fore wing 1.3-1.5.
