Cryptopimpla aspeculosus Kang & Lee sp. n. Fig. 1

Male.

Forewing 7.6 mm (7.6-7.7 mm, n = 2), body 10.3 mm (10.3-10.5 mm, n = 2) long (Fig. 1A).

Head.

In dorsal view, 2.3 times as wide as long, and distinctly narrowed behind, densely and coarsely punctate with coriaceous between punctures. Diameter of median ocellus 0.6 times as long as distance between lateral ocellus and compound eye. Flagellum with 38 elongated flagellomeres; 1st flagellomere 3.5 times as long as wide. Occipital carina narrowly curved from above, reaching hypostomal carina above the base of mandible. Face weakly convex medially, 1.7 times as wide as long, densely and rather coarsely punctate, without carina between antennal sockets (Fig. 1B). Clypeus weakly convex; 2.3 times as wide as long, with sparse punctures and blunt fore ridge. Malar space 0.7 times as long as basal width of mandible.

Mesosoma.

Coarsely and densely punctate on the coriaceous surface; 1.6 times as long as high. Notaulus long and shallow. Epicnemial carina reaches near the ventral hind margin of pronotum, but does not join it. Propodeum slightly straight in lateral view, with posterior transverse, pleural carinae and weak median longitudinal carina; propodeal spiracle moderately large, oval (Fig. 1C). Legs very slender; hind femur 7.1 times as long as wide; hind inner tibial spur 0.42 times as long as 1st tarsal segment; ratio of hind tarsal segments are 5.2:2.3:1.5:1.0:1.3; all tarsal claws simple. Forewing with incomplete 3rs-m; 2m-cu with a single bulla; 1cu-a vein weakly postfurcal; vein 2-Cu as long as 2cu-a. Hindwing with 8 distal hamuli; vein 1/cu about 1.5 times as long as cu-a (Fig. 1E).

Metasoma.

1st tergite 1.7 times as long as wide, with prominent spiracle at basal 0.45 (Fig. 1D). 2nd tergite square. All tergites finely coriaceous. 4th and apical third of 3rd tergite with sparse punctures.

Color.

Body black; basal half of clypeus and mandible, palpi, collar, hind ventral and dorsal angle of pronotum, wide lateral stripe on mesonotum from tegula to mid lobe, tegula, subtegular ridge, fore and mid coxa, fore trochanter from below and hind tarsus, except basal 3/4 of basitarsus and apical half of last tarsal segment yellow; fore and mid femora, tibiae and tarsi reddish, hind tibia and hind basitarsus (except apical 1/4) red; apical half of last tarsal segment of hind leg dark brown.

Female.

Unknown.

Paratype.

1 male, South Korea, GG, Namyangju-si, Bogwangsa, 13 April 1984, J.W. Lee (YNU).

Distribution.

South Korea (new record).

Etymology.

The name comes from Latin “speculo”, aspeculosus meaning "without areolet".

Remarks.

The species is similar to C. brevigena , from which it differs by the presence of pleural and posterior transverse carinae and the entirely black face. Furthermore, the malar space in C. brevigena is 0.3 times as long as the basal width of the mandible while in C. aspeculosus it is 0.7 times. Additionally, this species is easily separated from other two species ( C. carinifacialis and C. pentagonalis ) as follows: the 3rs-m vein in C. aspeculosus is only present in the basal part, while in the other two species have a complete 3rs-m vein.
