Diagnosis.
Paraleochara
can be distinguished and characterized from the other genera within the tribe
Aleocharini
as follows: body medium sized, pubescent, and strongly glossy; ligula elongate, somewhat acute apically; carina on each side of ventral side of head absent; each elytron with posterolateral corners not sinuate; legs long and slender, with 5-5-5 tarsal formula; intercoxal process of mesoventrite very short and wide, with broadly truncate posterior margin; intercoxal process of metaventrite exceptionally long, much longer than that of mesoventrite; female spermatheca with large spherical head, fused with its neck.
See
Cameron
(1920
,
1939
) and
Park & Ahn (2010a)
for further taxonomic information and references. Mouthpart characters of
P. fungivora
(as
Paraleochara translata
), the
type
species of the genus, have been described in detail (
Sawada, 1982
).
Comments.
This genus includes only the
type
species from the Oriental region [
Sri Lanka
,
Singapore
, Borneo, Sulawesi, New
Guinea
(
Pace, 2014
); the Malay Peninsula (present study)] but we found another species from
East Asia
, discussed below.
Paraleochara
belongs to the
Tetrasticta
generic group, which consists of eight genera (see
Maruyama, 2004b
;
Maruyama
et al
., 2011
).
