( Figure 4A–J View Figure 4 , Table 1)

Specimen examined

Holotype. [Korea] ( YNU): 1 male, Yongsan-dong , Jeongeup-si, JB Jeollabuk-do, South Korea, 19 May–19 June 2004, MT, M.K. Yun leg.

Description (male)

Colour. Body testaceous to black. Head black except mandible dark testaceous; antenna testaceous except pedicel pale testaceous. Mesosoma dark testaceous; forewing hyaline, wing veins yellow except pterostgima testaceous; legs testaceous except tibia and tarsi yellow. Metasoma testaceous.

Morphology. Body ( Figure 4A View Figure 4 ) 3.27 mm long.

Head ( Figure 4B–D View Figure 4 ): 1.0 × as long as wide with straight posterior margin and sides of head converging from eye to posterior margin in full face view; frons and vertex microreticulate with small and shallow punctures, separated each other by 3.0–5.0 × as their diameters; mandible with four teeth, outer surface with some hairs; anterior margin of clypeus short and small with median lobe convex ( Figure 4C View Figure 4 ); from scape to flagellomere III in ratio of 2.5: 1.0: 1.5: 1.3: 1.4 in length; from scape to flagellomere III and XI 2.8, 1.3, 1.7, 1.5, 1.8 and 3.0 × as long as wide respectively ( Figure 4D View Figure 4 ); compound eye 0.24 mm, long and smooth without hairs; LE 0.9 × as wide as OOL; WF 1.7 × as wide as WOT; anterior angle of ocellar triangle obtuse; POL 2.0 × as wide as AOL; OOL 1.2 × as wide as WOT ( Figure 4B View Figure 4 ).

Mesosoma ( Figure 4E, G View Figure 4 ): pronotum 0.3 × as long as wide, micro-reticulate with a few small and shallow punctures, posterior margin concave broadly; notaulix welldeveloped and divergent anteriorly, scutellum with anterior transverse deep groove; metanotum well-developed; propodeal disc short, 0.8 × as long as maximum width with convex lateral margin and concave posterior margin in dorsal view, median, lateral and transverse carinae present, submedian and sublateral carinae absent, anterior one-third of disc with irregular rugose, median longitudinal area depressed with median carina ( Figure 4F View Figure 4 ), remaining area smooth and shiny; propodeal declivity without longitudinal carina. Forewing: metacarpus present, about 2.5 × as long as pterostigma ( Figure 4G View Figure 4 ).

Metasoma ( Figure 4H View Figure 4 ): petiolate and shining, without punctures, with few hairs in latero-distal parts of each tergum in dorsal view.

Genitalia ( Figures 4I, J View Figure 4 ): paramere long and thick, longer than aedeagus, distal margin narrowly rounded with dense hairs; aedeagus bottle-shaped, basal margin broadly concave, thickest at distal one-third part; digitus shorter than aedeagus, inner margin and distal part of aedeagus well sclerotized ( Figure 4J View Figure 4 ), hypopygium long, median projection well developed with two pairs of small projections, distal margin concave, median area well sclerotized ( Figure 4I View Figure 4 ).

Measurements. See Table 1 for biometric measurement data.

Distribution

South Korea (JB).

Etymology

The specific name is derived from the diagnostic characteristic of four mandibular teeth.

Diagnosis

This species is similar to P. ishana Terayama, 2006 from Japan, but can be distinguished by its four mandibular teeth (five teeth in P. ishana ); convex median lobe of clypeus (broadly round in P. ishana ); scape 2.0 × as long as wide (3.0 × as long as wide in P. ishana ); notauli anteriorly divergent (parallel in P. ishana ); propodeal disc short, 0.8 × as long as maximum width (1.3 × as long as width in P. ishana Terayama ).
