MATERIAL EXAMINED. Holotype – ♀, China: Yunnan, [CH07-19] Dehong

Dai Aut[onomous]. Pref. mount[ain] Range, 31 km E Luxi, 2280 m, 24°29'31'' N,

98°52'58'' E, second[ary] pine forest with old deciduous trees, litter sifted, 3.VI 2007,

A. Pütz [ OLML].

DIAGNOSIS. FEMALE. Genal carina distinct, forming tooth at hypostomal carina junction. Scutellar scale narrow, T2 anteriorly with a pair of transversely arranged, circular spots of silver setae, T2 apical band of black setar medially expan-

ded. T3 with interrupted medially band of dense silver setae. Pygidial area carinated laterally, glabrous shiny. Body black; mesosoma laterally, coxae, femora, T2 except posterior band, S2 except posterior band ferruginous-red. MALE unknown.

DESCRIPTION. FEMALE. Body length 7.8 mm. Ratio of head width and pronotal maximal width 98:85. Ratio of mesosoma length and pronotal maximal width

125:85. Mandible bidentate, not excised beneath. Clypeus anteriorly transversely concave, smooth and shiny, posteriorly subtriangular, elevated and punctate, with median tubercle. Antennal tubercle carinate above; first flagellomere 1.2 × as long as its maximal width, 1.4 × as long as flagellomere 2. Genal carina distinct, forming tooth at hypostomal carina junction. Frons, vertex and gena with dense coarse punctures. Humeral angle of mesosoma prominent. Ratios of width at humeral angle,

widest point of pronotum, anterior spiracle, propodeal spiracle and widest point of propodeum 80:85:80:70:80. Scutellar scale narrow. Mesosoma dorsally and posterior propodeal face with coarse dense confluent punctures. Pleuron smotth, propodeum laterally with a few shallow punctures. Lateral and posterior propodeal faces separated by wavy subdentate carina. Legs with sparse suberect whitish and black setae. Meso- and metatibia each with two rows of 4–5 fuscous spines. Metatibio-

tarsal ratios of 90:40:25:18:10:18. T1 with elongate shallow sparse punctures. T2

with separate punctures, posteriorly denser. T3–T5 with fine dense small punctures.

S1 with simple longitudinal carina. S2 with sparse large punctures. S3–S5

posteriorly with fine dense confluent punctures. Pygidial area carinate laterally,

glabrous shiny.

Colour and setation. Body black, mesosoma laterally, coxae, femora, T2 except posterior band, S2 except posterior band ferruginous-red. Mandible, antennae, mesosoma ventrally tinted reddish. Tibial spurs reddish. Frons and vertex with sparse suberect and erect black setae; gena with sparse recumbent greyish setae. Mesosoma dorsally and posterior propodeal face with sparse suberect fuscous to black setae.

Pleuron and propodeum laterally with pale yellow recumbent micropubescence. T1

and T6 with long, sparse erect greyish to black setae. T2 anteriorly with a pair of bilateral circular spots of pale yellow setae, ratios of spot diameter, spot interspace and longitudinal eye diameter 20:40:40, posteriorly with medially widened band of black setae. Felt line on T2 rufous. T3 with interrupted medially band of dense silver setae. T4 and T5 with erect black setae. All metasomal sterna with sparse whitish setae, which form apical fringe on S2 and S3.

DISTRIBUTION. China (Yunnan).

REMARKS. The female of this new species is similar to that of T. basirufus

(Chen, 1957), but differs by having interrupted medially band of silver setae on T2

(non interrupted band in T. basirufus ) by narrower mesosoma before propodeal spiracles (0.82 × maximal mesosomal width in T. cheni vs. 0.90 × in T. basirufus ).

ETYMOLOGY. The specific name is dedicated to Prof. Chen Xue-xin for his contribution to the study of Chinese Mutillidae .
