Type material.
Holotype: South Korea • ♀; 1549, Chusan-ri , Ongnyong-myeon, Gwangyang-si, Jeollanam-do; 35°01.8'N, 126°36'E; 12–27 Oct. 2019 by malais trap; leg. S. Kim; GenBank: PV 165859 ( Ap 23018 ) GoogleMaps . Paratype: South korea • 1 ♀; same location as for holotype; 24 Sep. – 08 Oct. 2019 by Malaise trap; leg. S. Kim; GenBank: PV 165860 ( Ap 23022 ) GoogleMaps .
Diagnosis.
In some morphological characters (number of antennal segments, maxillary palps, and labial palps, central carinae of dorsal petiole), Lipolexis sternaulata sp. nov. is similar to the other three gracilis group species, L. gracilis , L. pelopsi , and L. depressiceps sp. nov. However, it clearly differs from them in having distinctly developed sternaulus (= precoxal sulcus) on the anterior part of the mesopleuron, not reaching the metapleuron (while weakly impressed in other species), shorter tibia than L. gracilis and L. pelopsi (length / maximum length ratio = 8.6, while 14.0 and 17.4 in L. gracilis & L. pelopsi ), elongated ovipositor sheath (length / width ratio = 3.2–4.0 at base and 9.7–10.6 at tip, while 3.1 at base and 9.1 at tip in L. pelopsi , 2.9 at base and 9.6 at tip in L. gracilis and 3.1 at base and 8.8 at tip in L. depressiceps sp. nov.), and elongated pterostigma (length / width ratio = 2.6–2.7, while 2.3–2.6 in other species).
Description.
Female. Length of body about 2.4 mm (Fig. 3 A View Figure 3 ). Length of forewing 1.3 mm (Fig. 3 K View Figure 3 ).
Head. Width of head 1.5 × its maximum length in dorsal aspect; occipital carina gently concave; head 1.3 × wider than mesosoma, with sparse long setae; eye 1.6 × as long as temple in dorsal aspect; OOL 3.1 × as long as posterior ocellus diameter; ratio of OOL: AOL: POL = 26: 10: 10 (Fig. 3 G View Figure 3 ). Eyes oval, sparsely setose; face with sparse long setae; width / height ratio = 1.2; densely long setae around antennal socket; tentorial index = 0.3; clypeus oval and with 7 long setae; malar space 0.2 × as long as longitudinal eye diameter (Fig. 3 D View Figure 3 ). Antenna 12 - segmented; F 1 equal to F 2; F 1 and F 2 3.4–3.6 × and 3.5–3.8 × as long as their width at the middle, respectively; F 1 and F 2 with three longitudinal placodes (Fig. 3 B, C View Figure 3 ). Maxillary palp with four palpomeres, labial palp with one palpomere.
Mesosoma. Mesoscutum with notaulices on anterolateral margin, effaced dorsally (Figs 3 E View Figure 3 , 6 F View Figure 6 ). Dorsal surface smooth, with two rows of 6–8 long setae along the dorsolateral part of mesoscutum, respectively; scutellum nearly triangular, with three and four long setae on each side (Fig. 3 E View Figure 3 ). The precoxal sulcus is present on the anterior part of the mesopleuron, not reaching the metapleuron (Fig. 6 F View Figure 6 ). Propodeum areolated, areola length / width ratio = 1.3 (Fig. 3 F View Figure 3 ). Pterostigma 2.6–2.7 × as long as width; Pterostigma 1.1 × as long as vein R 1 (= metacarpus); r and RS vein extended (Fig. 3 J View Figure 3 ).
Leg. Hind femur length / width ratio = 4.3; hind tibia length / width ratio = 11.3; hind femur: hind tibia: hind tarsus = 1: 1.6: 1.7 (Fig. 3 L, M View Figure 3 ).
Metasoma. Petiole elongated, wide at base, slightly narrowing towards the apex; 3.1–3.3 × as long as wide at spiracles; distinctly prominent central carinae, situated along the dorsal surface of the petiole, and bifurcate near of spiracles; dorsolateral part of posterior spiracles is concave on each side (Fig. 3 H, I View Figure 3 ). Ovipositor sheath elongated, wide at base, curved downwards; ratio of ovipositor sheath length / width = 3.2–4.0 at base and 9.7–10.6 at tip (Fig. 3 K View Figure 3 ).
Colour. Antenna brown; scape and pedicel yellowish brown, F 1 yellowish brown at least basal 1 / 3 partly yellowish brown, gradually brown to apex. Head, face and clypeus with mouthparts pale brown. Mesosoma pale brown and metasoma brown; mesoscutum brown; petiole pale brown. Legs pale brown with dark apices.
Distribution.
South Korea.
Etymology.
Lipolexis sternaulata sp. nov. is derived from the Latinised form of the precoxal sulcus, referring to its distinctly developed precoxal sulcus on the mesopleuron.
