( Figs 1 View FIGURE 1 f, 2e, 3e, 4c, 5e, 6e)
Diagnosis. Body black, except tergites 2 onwards reddish brown; mesoscutum polished, almost without hairs; metapleuron coarsely rugose-punctate; propodeum with additional transverse carinae, superomedia area closed, petiolar divided into three subareas by longitudinal carinae; fore and mid femora normal, without median ventral tooth.
Description. (Holotype male). Body length 6.2 mm, fore wing 4.7 mm. Head. Antenna with 24 flagellomeres, first flagellomere 1.4x length of second; diameter of lateral ocellus 0.7x ocellar-ocular distance; frons polished, with sparse hairs; inner margins of eyes weakly concave above antennal sockets, parallel ventrally; face 0.8x as high as wide, pubescent; clypeus convex, about 0.5x as high as wide, separated from face by weak clypeofacial suture, apical margin round; malar space equal to basal width of mandible; mandible upper tooth slightly longer than lower tooth; palpi formula 5:4; occipital carina complete, meeting hypostomal carina about 1.4x basal mandible width from base of mandible, forming flange ventrally after meeting hypostomal carina.
Mesosoma . Pronotum polished, with some hairs on posterior corner; mesoscutum polished, impunctate; mesoscutum 1.2x as long as wide at anterior level of tegulae; scutellum strongly convex, pubescent, lateral carina present at base; mesopleuron densely setose except concave area near mesopleural suture bare and polished, epicnemial carina present on lower half of mesopleuron; metapleuron coarsely rugose-punctate, pubescent, submetapleural carina complete, forming small lobe anteriorly; propodeum moderately convex, dorsally striate, lateral longitudinal, lateromedian longitudinal and posterior transverse carinae present, many transverse striations attached to lateromedian and lateral longitudinal carinae, petiolar area foveolate by carinae, pleural area rugose, pubescent. Legs unmodified, fore and mid femora without teeth ventrally; fore femur 4x as long as wide; hind leg with femur 4.7x as long as wide, length 0.7x tibia, tibia 10x as long as apical width; basitarsus 0.3x tibia, 0.35x tarsus, 1.6x second tarsomere, fifth tarsomere longer than third. Fore wing with vein Rs&M basad of cu-a, vein cu-a strongly inclivous, 2 rs-m about 0.8x distance between 2 rs-m and 2 m-cu, vein Cu 1 a separated from 1 m-cu by 1.25x length of vein Cu 1 b; hind wing with vein M+Cu strongly curved, first abscissa of vein Cu 1 1.3x as long as vein cu- a, second abscissa of vein Cu 1 present.
Metasoma. Tergites polished, with scattered short hairs; first tergite 1.7x as long as apical width, dorsolateral carina complete, median longitudinal carina extending over oblique groove; second tergite 0.8x length of first tergite, 0.85x as long as apical width; third tergite shorter than second, basal and apical oblique grooves of tergites 2–3 moderately deep, rhombic areas convex; first sternite rugose, extending to level of spiracle, round convex apically.
Colour. Black, except mandible, palpi, tegula, subalar prominence, legs reddish brown; metasomal tergite 2 onwards reddish except smooth transverse apical bands black; wings yellowish brown.
Female. Unknown.
Comparison. This species belongs to the quadrisculpta group ( Townes & Townes 1960). It is similar to A. carinator (Aubert) in its petiolar area divided into three sub-areas by carinae. However, the propodeum of the new species has an additional, anterior transverse carina, the metasoma is partly red (all black or dark brown in A. carinator ) and the fore femur is slenderer than in A. carinator (strongly swollen in A. carinator ).
Etymology. This species is named after Mark Shaw, who has reared so many British polysphinctines and substantially improved our knowledge of their biology.
Distribution. Currently known only from Sa Pa, Lao Cai Province, North of Vietnam ( Fig. 8 View FIGURE 8 ).
Ecological notes. The single specimen was collected in montane evergreen forest at an elevation of 1,700 m a.s.l.
Material examined. Holotype: 3 ( OMNH), Lao Cai, Sa Pa, 1700 m a.s.l, 30.v.1997, hand net, R. Matsumoto leg.
