Cryptopimpla pentagonalis Kang & Lee sp. n. Fig. 4

Female.

Forewing 9.3 mm (8.8-9.3 mm, n = 7), body 9.8 mm (9.5-9.8 mm, n = 7), ovipositor sheath 2.6 mm (2.4-2.6 mm, n = 7) long (Fig. 4A).

Head.

In dorsal view, 3.4 times as wide as long, narrowed behind distinctly, densely punctate between punctures. Diameter of median ocellus 0.77 times as long as distance between lateral ocellus and compound eye. Flagellum with 42 (in paratypes 41-43, n = 6) elongated segments; 1st flagellomere 5.0 times as long as wide. Occipital carina weakly curved from above, reaching hypostomal carina at base of mandible. Face slightly convex medially, 1.4 times as wide as long, densely and rather coarsely punctate (Fig. 4) without carina between antennal sockets (Fig. 4B). Clypeus convex; 1.8 times as wide as long with sparse punctures and blunt fore ridge. Malar space 0.6 times as long as basal width of mandible.

Mesosoma.

Densely and coarsely punctate on the coriaceous surface, 1.6 times as long as high. Notaulus short and very weak. Epicnemial carina reaching near ventral hind margin of pronotum. Propodeum convex in lateral view, with only posterior transverse and pleural carinae; spiracle moderately large, oval (Fig. 4C). Legs slender; hind femur 6.5 times as long as wide; hind inner tibial spur 0.42 times as long as basitarsus; ratio of hind tarsal segments 6.0:2.7:1.8:1.0:1.3; tarsal claws fully pectinate. Forewing with pentagonal areolet; vein 3rs-m distinctly present; 2m-cu with two bullae; 1cu-a vein weakly postfurcal; vein 2-Cu slightly longer than 2cu-a. Hindwing with 9 distal hamuli; vein 1/cu about 2.0 times as long as cu-a, reclivous (Fig. 4E).

Metasoma.

1st tergite 2.5 times as long as wide apically, without median and lateral carinae; spiracle situated before middle (Fig. 4D). 2nd tergite 1.0 times as long as apical width. Ovipositor sheath 0.63 times as long as hind tibia. Ovipositor straight and compressed, with subapical dorsal notch.

Color.

Black. Inner face of orbit, ventral part of frontal orbit, spot on top of eye orbit opposite to lateral ocellus, facial orbit, fore ridge of pronotum medially, thin lateral stripe on antero-lateral portion of mesonotum and 2nd to 4th tarsal segments of hind leg yellow. Apical half of clypeus, fore tibia, and tarsus reddish-brown.

Male.

Unknown.

Specimens examined. Holotype:

South Korea: female, GW, Jeongseon-gun, Gohan-eup, Haiwongil, Mountain condo, 9 July 2010 (YNU).

Paratypes.

2 females, GW, Jeongseon-gun, Gohan-eup, Haiwongil, Mountain condo, 9 July 2010 (YNU); 3 females, GW, Jeongseon-gun, Gohan-eup, Mt. Baegunsan, 9 July 2010 (YNU); 1 female, GW, Wonju-si, Panbu-myeon, Mt. Baegunsan, 25 May– 26 July 2012, H.Y. Han (YNU).

Distribution.

South Korea (new record).

Etymology.

The name comes from Latin “Pentagonum”, pentagonalis means "pentagon areola".

Remarks.

With the pentagonal areolet, black metasoma, hind coxa and femur, this species is similar to Cryptopimpla henanensis Sheng, but differs in the propodeum structure and body coloration; in C. pentagonalis the mesosoma is entirely black while in C. henanensis it has more yellow spots. The latter species also has more flagellomeres; in C. henanensis with 46 segments while in C. pentagonalis with an average of 42 segments.
