Type
species
:
Smicromyrme taiwanus
Tsuneki, 1993
, ♂,
Taiwan
, by original designation (junior subjective synonym of
Mutilla friekae
Zavattari, 1913
, ♂,
new synonym
).
Gender.
Masculine (Article 30.2.4 of the
ICZN
1999;
Lelej & Brothers 2008
). Because the gender of
Taiwanomyrme
is masculine the endings of adjectival specific names are changed to agree where necessary.
Diagnosis.
MALE. Mandible basally beneath neither emarginated nor toothed. Scape beneath with one or two carinae (usually one stronger); flagellomere 1 subequal to flagellomere 2. Mesoscutellum evenly convex, not at all gibbous, without median longitudinal carina. Tegula long, extending beyond posterior margin of mesoscutum. Metasomal tergum 2 with well developed lateral felt line; sternum 2 with short lateral felt line (sometimes reduced to a few microsetae). Volsellar cuspis long, shorter than gonostylus, with small paracuspis; penial valve apically swollen or hook-like. FEMALE. Clypeus anteriorly transversely concave, posteriorly triangularly elevated, punctate. First flagellomere 1.5 × as long as flagellomere 2; antennal tubercle carinate above. Scutellar scale present, narrow or wide. Metasomal sternum 1 with simple longitudinal carina. Pygidial area smooth or microstriate, laterally carinate.
Mesosoma
black, metasoma black with segments 1–3 and legs ferruginous-red.
Distribution
. Palaearctic and Oriental
China
(Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Hunan, Sichuan, Guizhou, Yunnan,
Taiwan
).
Species included
. Five species:
T. friekae
(
Zavattari, 1913
)
, ♂,
T. impressus
(
Chen, 1957
)
, ♂,
T. impressoides
Tu, Lelej et Chen
,
sp. nov.
, ♂,
T. basirufus
(
Chen, 1957
)
, ♂, ♀ and
T. latisquamula
Tu, Lelej et Chen
,
sp. nov.
, ♀.
Sex association
. The female of the
type
species has not been recognized; the female of another species was associated and identified as
Smicromyrme basirufus
(
Chen 1957
)
.
Remarks.
This genus is placed in the tribe Petersenidiini and includes males with symmetrical genitalia. The male of
Taiwanomyrme
is similar to that of
Radoszkowskitilla
Lelej, 2005
from
India
and
Sri Lanka
by having the mandible beneath without a large basal tooth, but differs by having metasomal sternum 2 with a very short lateral felt line (metasomal sternum 2 without any lateral felt line in
Radoszkowskitilla
), the scape beneath with two carinae (scape beneath polished in
Radoszkowskitilla
), the volsellar cuspis long with a small paracuspis (volsellar cuspis only slightly longer than penial valve, without a paracuspis in
Radoszkowskitilla
). The male of
Taiwanomyrme
is similar to that of the Oriental genus
Promecidia
Lelej,
1996
in the tribe Trogaspidiini (
Lelej 1996
,
2005
) by having the mandible not excised beneath basally and by the simple mesoscutellum, but differs in the long symmetrical penial valves (short slightly asymmetrical penial valves in
Promecidia
). In the tribe Petersenidiini the female of
Taiwanomyrme
is similar to that of
Radoszkowskitilla
by having black
mesosoma
, but easily differs by having not elongated
mesosoma
(1.4 × as long as its maximum width
vs.
1.85 × in
Radoszkowskitilla
), disc of metasomal tergum 2 neither flattened nor carinate laterally (disc of metasomal tergum 2 flattened and longitudinally carinate laterally in
Radoszkowskitilla
). The differences of female of
Taiwanomyrme
from other ones of the tribe Petersenidiini with the similar shape of pygidial area are given in the key below.
Females may be added to the key to Oriental genera of the tribes Petersenidiini and Trogaspidiini (
Lelej 2005, p. 151
) as follows (additional couplet in bold):
