FIGURES 74, 75.
Erythmelus (E.) tingitiphagus
(female). 74. Antenna (Barquisimeto, Lara, Venezuela). 75. Forewing (Belém, Pará, Brazil). Scale bars = 0.1 mm.
Diagnosis.
Erythmelus (E.) tingitiphagus
was only provisionally assigned to the
flavovarius
species group by
Triapitsyn (2003)
. It indeed belongs in there. This distinctive, minute species (body length
440–510 µm
) was redescribed and illustrated by
Triapitsyn (2003)
. It is somewhat similar to
E. (E.) pastoralis
Ogloblin
from
Argentina
. The relative length of the longest marginal cilia to the greatest width of the forewing (1.8– 2.1:
1 in
E. (E.) tingitiphagus
and about 1.4:
1 in
the
holotype
of
E. (E.) pastoralis
), and especially the number and distribution of the setae on the forewing blade (
Figs. 75
,
89
, respectively) allow for separation of these two species. The funicle of the female antenna is normally 6–segmented (
Fig. 74
) but often it is 5–segmented due to a fusion of any two neighboring funicular segments or a loss of one of the funicular segments, usually of F3 or F4 (
Triapitsyn 2003
).
Distribution.
Argentina
,
Brazil
,
Venezuela
(
Triapitsyn 2003
), and
Colombia
(new record).
Hosts.
Tingidae
:
Corythaica cyathicollis
(Costa)
,
C. monacha
(Stål)
,
Gargaphia lunulata
(Mayr)
,
Leptodictya tabida
(Herrich-Schaeffer)
,
Leptopharsa heveae
Drake & Poor (
Triapitsyn 2003
)
, and also
Leptopharsa gibbicarina
Froeschner
(new record). According to the labels on several slides with the specimens collected by A.A. Ogloblin in Loreto,
Misiones
,
Argentina
, some of them were reared from eggs of an unidentified species of
Tingidae
.
