Apterodela unipunctata
(Fabricius, 1775)
,
new combination
Rivalier (1950)
described
Apterodela
as a subgenus of
Cylindera
and designated
C
.
ovipennis
Bates, 1883
as the type. Given the polyphyly of
Cylindera
(
Gough et al. 2019
; this study) and a monophyletic and morphologically distinct
Apterodela
(
Sota et al. 2011
)
, we recognize the clade as a full genus.
The Nearctic species,
A. unipunctata
, is strongly supported (Bootstrap = 98) as sister to
A
.
ovipennis
in our phylogeny (
Fig. 1
) and is remarkably similar in morphology to species of
Apterodela
from Asia. Like the other members of the genus, it is large (14–18 mm), with a coarsely striated concave frons, flattened ovate elytra with reduced maculations, dark infuscations and prominent subsutural foveae.
Ecologically,
A
.
unipunctata
is unlike any other species of Nearctic
Cicindelini
. Adult beetles are typically found when they cross forest trails and openings, but they also frequent darker closed-canopy forested areas where they may hunt in or on the leaf litter. The first author has collected beetles in dense late-succession oak forest in areas that were over 100m from a trail or opening. It is quite likely that most casual observations of this species are biased towards edges, as it is more likely to be seen when crossing trails and light gaps. Asian
Apterodela
species share similar forest-dwelling natural history and affinity for leaf litter (

).
