Diagnosis.
In some morphological characters (number of antennal segments, maxillary and labial palpomeres, central carinae of dorsal petiole), Lipolexis depressiceps sp. nov. is similar to the other three gracilis group species, L. gracilis , L. pelopsi , and L. sulcata sp. nov.. However, it clearly differs from them in having deeply depressed and anteriorly narrowed occipital carina (partially obscured in dorsal aspect, while distinctly visible in other species), distinctly elongated F 1 and F 2 (length / width ratio = 4.7 and 4.3, while <4.0 in other species), shorter pterostigma / R 1 ratio (0.8, while 1.0– 1.1 in L. gracilis , 0.9–1.1 in L. pelopsi and 1.1 in L. sulcata sp. nov.), and more elongated hind femur (length / width = 5.2, while <4.5 in other species).
Description.
Female. Length of body about 3.0 mm (Fig. 2 A View Figure 2 ). Length of forewing 1.5 mm (Fig. 2 J View Figure 2 ).
Head. Width of head 1.5 × its maximum length in dorsal aspect; occipital carina narrow and deeply compressed anteriorly; head 1.3 × wider than mesosoma, with sparse long setae; eye 1.7 × as long as temple in dorsal aspect; ocello-ocular line (OOL) 3.1 × as long as posterior (= lateral) ocellus diameter; ratio of OOL: antero-posterior ocellar line (AOL): postero-ocellar line (POL) = 25: 10: 14 (Fig. 2 G View Figure 2 ). Eyes oval, sparsely setose; face with densely long setae; width / height ratio = 1.1; tentorial index = 0.4; clypeus oval with 12 long setae; malar space 0.1 × as long as longitudinal eye diameter (Fig. 2 D View Figure 2 ). Antenna 12 - segmented; F 1 equal to F 2; F 1 and F 2 4.7 × and 4.3 × as long as their width at the middle, respectively; F 1 with three longitudinal placodes and F 2 with four longitudinal placodes (Fig. 2 B, D View Figure 2 ). Maxillary palp with four palpomeres, labial palp with one palpomere.
Mesosoma. Mesoscutum with notaulices on anterolateral margin, effaced dorsally (Figs 2 E View Figure 2 , 6 E View Figure 6 ). Dorsal surface smooth, with two rows of 9–10 long setae along the dorsolateral part of mesoscutum; scutellum nearly triangular, with 2 long setae on each side (Fig. 2 E View Figure 2 ). The precoxal sulcus is weakly impressed on the anterior part of the mesopleuron (Fig. 6 E View Figure 6 ). Propodeum areolated, areola length / width ratio = 1.1 (Fig. 2 F View Figure 2 ). Pterostigma 2.4 × as long as width; pterostigma 0.8 × as long as vein R 1 (= metacarpus); r and RS vein extended (Fig. 2 J View Figure 2 ).
Leg. Hind femur slender, length / width ratio = 5.2; hind tibia length / width ratio = 11.6; hind femur: hind tibia: hind tarsus = 1: 1.6: 1.8 (Fig. 2 L, K View Figure 2 ).
Metasoma. Petiole elongated, 3.1 × as long as wide at spiracles; distinctly prominent central carinae, situated along the dorsal surface of the petiole, start at the anterior part and bifurcate near spiracles; dorsolateral part of petiole posterior of spiracles concave on each side (Fig. 2 H, I View Figure 2 ). Ovipositor sheath slender and long, wide at base, curved downwards; ratio of ovipositor sheath length / width 3.1 at base and 8.8 at tip (Fig. 2 K View Figure 2 ).
Colour. Antenna brown; scape and pedicel yellowish brown, F 1 at least partly yellowish brown. Head and face black, clypeus with mouthparts yellowish brown. Mesosoma and metasoma brown; mesoscutum black; petiole brown. Legs pale brown with dark apices.
Distribution.
South Korea.
Etymology.
Lipolexis depressiceps sp. nov. is derived from the Latin words depressus (meaning pressed down or flattened) and ceps (meaning ‘ head’), referring to its distinctly anteriorly depressed vertex in dorsal aspect.
