Remarks
. Comprising 39 described species,
Tetanocera
is the fourth largest genus of
Sciomyzidae
. According to
Rozkošný (1987)
and
Vala
et al
. (2012)
, 20 species are known from the Palearctic Region, 30 species are known from the Nearctic Region (with 1 species,
T. plumosa
, extended into the Neotropical Region), and 2 species are known from the Oriental Region.
Before our study, 6 species of
Tetanocera
(
T. arrogans
,
T. chosenica
,
P. elata
,
T. ferruginea
,
T. ignota
, and
T. nigrostriata
) had been recorded from
China
(
Knutson 1977
; Rozkošný &
Elberg 1984
;
Rozkošný 1987
;
Li, Yang & Gu 2001
). The
type
locality of 2 species are in
China
:
P. ignota
, whose
type
locality is
Tibet
, and
T. nigrostriata
, whose
type
locality is Kunming (
Yunnan Province
). During our study we determined about 7 species new to
China
, bringing to at least 13 the number of species known from
China
. Although
Tetanocera
is found in both the Palearctic and Oriental Regions of
China
, most specimens of
Tetanocera
in our study were from the Palearctic Region of
China
.
According to the key of
Rozkošný (1987)
, only
T. latifibula
Frey, 1924
and
T. punctifrons
Rondani, 1868
, are both characterized by having 1 preapical seta on the posterior surface of the midfemur. In our study,
49 specimens
(
15 males
and
34 females
) were found to have this character, which means that each of the specimens is most likely to be either
T. latifibula
or
T. punctifrons
. The
49 specimens
were collected both from the Palearctic Region of
China
, including such areas as
Inner Mongolia
,
Liaoning Province
,
Hebei Province
, and
Beijing
and from the Oriental Region of
China
, and including such areas as
Sichuan Province
,
Henan Province
(Nanyang, Xinyang),
Yunnan Province
,
Guizhou Province
, and
Zhejiang Province
. Both
T. latifibula
and
T. punctifrons
have been reported only from the Palearctic Region before, so our records from the Oriental Region of
China
indicate that
Tetanocera
has a more extensive distribution than had been known.
