Holotype, ♂, China: Guizhou Province, Fanjingshan Mountain, Jinding, 1993.VII.12, collected by Xuexin Chen. Paratype: 3♂, same data as holotype .</p><p>Diagnosis. This new species resembles A. caeruleus Wu and Zhou, 1987 in having the thorax and propodeum with a blue metallic luster, the free margin of the clypeus straight and the apical margin of the pygidial plate straight. It can be distinguished from the latter by the following characters: only pronotum and propodeum with blue metallic luster (thorax entirely with blue metallic luster in A. caeruleus); in male, gastral tergum II with pair of round yellowish spots (no yellowish spot in A. caeruleus); pronotal collar, scutum and scutellum with evidently larger punctures (with evidently smaller punctures in A. caeruleus); propodeal enclosure as long as propodeal dorsum, with about 16 oblique longitudinal rugae (propodeal enclosure about as long as 5/6 of propodeal dorsum, with about six oblique longitudinal rugae in A. caeruleus).</p><p>Description. Male: Body length 6.1–7.5 mm. Head and thorax black, with the following yellow parts: clypeus except median brown spot at base, base of mandible, labrum, maxillary palpus, labial palpus, subantennal sclerite, spots on lower frons laterally, long spot between antennal sockets, scape beneath, and terminal portion of pronotal lobe; flagellum yellowish brown beneath, dark brown dorsally. Legs pale brown to dark brown except fore coxa largely, fore trochanter, fore femur, fore tibia beneath, mid coxa largely, mid trochanter, hind coxa apically, and hind trochanter pale yellowish brown. Wings pale yellowish brown, forewing with pale brown band on portion of submarginal cell II. Gaster brown or dark brown, with pair of round yellow spots on tergum II anterolaterally, pygidial plate yellowish brown. Pronotum with inconspicuous and propodeum with well-defined blue metallic luster. Clypeus and lower frons with sparse, short white setae, upper frons and vertex with dense, short pale yellowish brown or yellowish brown setae; thorax (except propodeal enclosure glabrous) with sparse or dense, white to pale brown, short setae; gastral terga I and II with few pale yellowish or pale brown long setae, remaining terga with sparse or dense pale yellowish brown or pale brown long setae (Fig. 1A).</p><p>Head. Vertex with dense, large punctures medially, with sparse, large punctures laterally. Upper frons with dense, large punctures, lower frons with sparse, median sized punctures; frons median furrow inconspicuous (Fig. 1B). Clypeus length: width = 14: 42, with sparse, median sized punctures, slightly bulging anteromedially, free margin of clypeus straight (Figs 1B, 1C). Mandible with one subapical inner tooth (Fig. 1C). Flagellomere I: II = 9: 11, apical segment of flagellum depressed on inner side (Fig. 1D). POL: OOL: OD = 10: 14: 6.</p><p>Mesosoma. Pronotal collar with dense, large punctures (Fig. 1E). Mesoscutum with dense, large punctures, admedian and parapsidal lines evident (Fig. 1E); scutellum with sparse, large punctures, median furrow shallow (Fig. 1F); mesopleuron with sparse, large punctures, upper portion with broad, transverse furrow. Metanotum with sparse, large punctures; metapleuron with sparse, small punctures, upper area with several transverse rugae. Propodeum with triangular enclosure, pointed at end, as long as propodeum dorsally; enclosure with about 16 oblique longitudinal rugae and about 6 short transverse rugae posteriorly, propodeum outside of enclosure with about 15 oblique transverse rugae; posterior surface of propodeum with longitudinal median ridge and several short, oblique rugae (Fig. 1F); lateral surface of propodeum with sparse, large punctures and several short, oblique rugae. First recurrent vein received by junction of submarginal cells I and II, second recurrent vein received by submarginal cell III (Fig. 1G); hindwing vein M diverging at point of cu-a (Fig. 1H).</p><p>Metasoma. Terga I and II polished, with few small punctures; terga III–VI with dense, small punctures (Fig. 1I); pygidial plate with dense, large punctures, terminal edge straight (Fig. 1J).</p><p>Female: unknown.</p><p>Distribution. China (Guizhou Province).</p><p>Etymology. The new specific name, cyanotaeniatus, is derived from the cyan- (blue, Greek origin) and - taeniatus (banded, Greek origin), referring to the fact that only pronotum and propodeum have the blue metallic luster, which is one of the important identifying characters of this species.</p></div>	https://treatment.plazi.org/id/038C87D2A3205A30EAA0FC1721955BBB	Public Domain	No known copyright restrictions apply.

Holotype, ♂, China: Ningxia Autonomous Region, Erlonghe Forest Farm, Botanical Garden, 2008. VI.3, collected by Ma Li.</p><p>Diagnosis. This new species resembles A. ratzeburgi Dahlbom, 1843 in having median furrow of frons conspicuous and reaching anterior ocellus, and all legs yellow or brown except hind coxa largely black. It can be distinguished from the latter by the following characters: free margin of clypeus depressed medially (free margin of clypeus straight in A. ratzeburgi); propodeal enclosure as long as propodeal dorsum (propodeal enclosure about as long as 4/5 of propodeum in A. ratzeburgi); clypeus largely black, long spot on lower frons laterally light gray white, fore coxa brown, pair of round spots on gastral tergum II anterolaterally light yellowish brown and evidently smaller (clypeus yellowish, long spot on lower frons laterally yellowish, fore coxa largely yellowish, pair of irregularly oval spots on gastral tergum II anterolaterally yellowish and evidently larger in A. ratzeburgi).</p><p>Description.

Head and thorax black; free margin of clypeus, labrum, base of mandible, maxillary palpus, labium, galea, flagellum beneath, and terminal portion of pronotal lobe yellowish brown; long spot on lower frons laterally light gray white. Largely yellowish brown are: fore coxa apically, fore trochanter, fore femur beneath, fore tibia beneath, mid coxa apically, mid trochanter beneath, mid femur beneath, mid tibia beneath, hind tibia beneath, and all tarsi; hind coxa largely black; remaining legs brown. Tergum I black, pair of round spots on gastral tergum II anterolaterally light yellowish brown, pygidial plate yellowish brown, remaining gaster brown or dark brown. Head and thorax (except propodeal enclosure glabrous) with sparse or dense, white to light brown, short setae; terga I and II with sparse, yellowish brown or light brown, long setae, remaining terga with sparse or dense, yellowish brown or light brown, long setae (Fig. 2A).</p><p>Head: Vertex with dense, large punctures; frons with dense, median sized punctures, median furrow shallow (Fig. 2B). Clypeus length: width = 10: 43, with dense, small punctures, slightly bulging anteromedially, free margin of clypeus straight (Figs 2B, 2C). Free margin of labrum with broad, deep depression medially (Fig. 2C). Mandible with one subapical inner tooth (Fig. 2C). Flagellomere I slightly shorter than II, apical segment of flagellum depressed on inner side (Fig. 2D). POL: OOL: OD = 5: 6: 3.</p><p>Mesosoma. Pronotal collar with dense, large punctures (Fig. 2E).

First recurrent vein received by submarginal cell II, second recurrent vein received by submarginal cell III (Fig. 2G); hindwing vein M diverging after cu-a (Fig. 2H).</p><p>Metasoma: Terga I and II polished, with sparse, small punctures; terga III–VI with dense, small punctures (Fig. 2I); pygidial plate with dense, large punctures, terminal margin slightly arcuately protruded (Fig. 2J).</p><p>Female: unknown.</p><p>Distribution. China (Ningxia Autonomous Region).</p><p>Etymology. The new specific name, labrisectus, is derived from the labr- (labrum, Latin origin) and— sectus (dissected, Latin origin), referring to the central portion of the labrum free margin with a broad, deep depression medially, which is one of the important identifying characters of this species.</p></div>	https://treatment.plazi.org/id/038C87D2A3265A32EAA0FCD021B058BF	Public Domain	No known copyright restrictions apply.
