Type
species:
Trelleora kryzhanovskiji

Diagnosis (
Gorochov, 2003
):
Body of small to medium size, brownish in colour; head more or less equal to anterior margin of pronotum, rostrum on head between the antennal cavities hardly narrower than scape, ocelli projecting. Pronotum distinctly widened at the posterior with lateral margins roundly bent into paranota, male tegmina with a large longitudinal mirror and long apical area, metanotal gland well-developed. Fore tibiae inner tympanum with a slit-like opening and outer tympanum oval in shape. Male supra anal plate short and rather simple; subgenital plate with apex narrowly rounded. In the male genitalia: the epiphallus is horseshoe-shaped, distinct membranous lobes are present between the lateral epiphallic lobes, ectoparameres are well developed and articulated with base of guiding rod, this base is almost fused with the mold of spermatophore attachment plate, this mold has more or less short apodeme, endoparameral apodemes are moderately long.
Composition:
the generic name
Trelleora
was established by A V
Gorochov (1988)
for the first time with
Trelleora kryzhanovskiji
Gorochov, 1988
as the
type
species by original designation; including 6 species presently (
Cigliano
et al
., 2019
); however, one more species,
Madasumma assamensis
Chopard, 1969
(Eastern
India
) possibly belongs to this group (
Gorochov, 2003
). According to
Gorochov (2003)
there exist two groups in the genus
Trelleora
on the basis of structures of the male genitalia.
Group I:
the long lateral lobes of the epiphallus have small denticles at the apex; large hook-like apical processes are absent; the short guiding rod is without upper processes; and possess comparatively small membranous lobes between the above-mentioned epiphallic lobes.
Species included in this group:
a)
Trelleora kryzhanovskiji
Gorochov, 1988
(Northern
Vietnam
and Southern
China
)
b)
T. suthepa
Ingrisch, 1997
(Northern
Thailand
)
c)
T. sonlensis
Gorochov, 1988
(Northern
Vietnam
)
Group II:
the short lateral lobes of the epiphallus with large hook-like apical processes and without small denticles at apex; the guiding rod with upper processes, which may be very long; and possess large membranous lobes between the epiphallic lobes.
Species included in this group:
a)
Trelleora fumosa
Gorochov, 1988
(Northern
Vietnam
)
b)
Trelleora consimilis
Gorochov, 2003
(
Vietnam
and
China
)
c)
Trelleora gravelyi
(
Chopard, 1928
)
(Northern
India
)
Distribution:
Specifically in the Oriental region.
