Description of
Planhoogenraadia wuchanica
sp. nov.
Description.
The shell of this species is elongate-elliptical with slight constriction in the aperture region. The shell is grey and consists of mineral particles of variable size embedded in organic cement. The dorsal side of the shell is evenly convex. The transition from the posterior of the shell to the ventral side is a circular arc without any angularity.
The aperture is narrow-elliptical, open on the ventral side. The upper lip of the aperture is extended forming a cap-like structure. This cap-like structure extends several microns (mean=22 µm) beyond the aperture and protrudes beyond the ventral surface of the shell terminating in a blunt lip. The height and the depth of the aperture are variable (from 10 to 38 µm). Coefficients of variation (CV) of shell length and height are less than 10% (
Table 1
), and CV values for most characteristics are lower than 15%, thus
P. wuchanica
can be considered a sizemonomorphic species.
Measurements.
The shell is large, with a mean length of 123 ± 8.3 µm, and mean width of 79 ± 9.5 µm. The shell is widest towards the center of the shell (mean=79 µm).
Habitat.
Soil of subtropical forest with dominated by
Cinnamomum camphora
(camphor tree) and the grass
Deyeuxia langsdorffii
.
Etymology.
The species name ‘
wuchanica
’ is in reference to the region ‘Wuchang’ in Wuhan City where the species was firstly observed.
Type specimens.
The
holotype
specimens of
Planhoogenraadia wuchanica
on which morphometric analyses were based are stored at
China
University of Geosciences, Wuhan,
China
(reference YJS17-1).
Type
locality.
The
type
locality of the new species is surface soil in
Cinnamomum camphora
dominated subtopic forest in the
Nanwangshan
and
Yujiashan mountains
, both are near to
Lake Donghu
(
Qin
et al
. 2013a
) and adjacent to the campus of
China
University of
Geosciences
in Wuhan, central
China
.
Ecology.
Individuals described here were located in subtopical soils in forest dominated by
Cinnamomum camphora
and
Deyeuxia langsdorffii
.
This habitat is similar to known habitats of other taxa in the genus
Planhoogenraadia
, which are abundant in subtropical and wet forest soils (
Table 2
).
