Material.

Holotype female, Moldova, Kišinev, 26.VI.1960, unknown aphid host and host plant, leg. Adaškevič; deposited in the IECR collection, slide mounted.

Diagnosis.

The new species differs clearly from all known Paralipsis species in having a strongly rugose propodeum (Figure 18) and scutellum (Figure 17) that are irregularly deep carinated, while other Paralipsis species are characterized by a smooth propodeum, sometimes with moderately expressed rugosities. Also, P. rugosa sp. n. is with F1 longer than F2 (the ratio between F1 and F2 is approximately 1.15) (Figure 16), while P. enervis , P. brachycaudi sp. n., and P. planus have F1 equal or subequal to F2. An exception is P. tibiator , which has much longer F1 than F2 (the ratio of F1 and F2 is about 1.4). Further, F1 and F2 are very short (proportion of length and width of F1 and F2 are 1.76 and 1.50, respectively) (Figure 16).

Description.

Female: Head rounded, smooth, narrower than mesosoma at tegulae, bearing dense setae (Figure 15). Head 1.1 times wider than long medially. Eyes oval, small, with scarse and long setae. Tentorial index 0.67. Clypeus with ten long setae (Figure 15). Maxillary and labial palpi with one palpomere each. Ocular-ocelar line: diameter of posterior ocellus: Postocelar line =12:4:14. Malar space: height of eye =11:13. Antenna 15-segmented, slightly thickened at apex (Figure 16). Scapus subapically with subparallel side at lateral view. Pedicel subspherical. F1 (Figure 16) longer than F2 and about 1.76 times as long as its maximum width at the middle, and F2 and F3 about 1.50 times as long as its maximum width at the middle. F1 and F2 without longitudinal placodes. Penultimate flagellomera 1.6 times as long as wide. F1, F2 and F3 without, and F4 with one short longitudinal placode. Flagellomeres covered uniformly with short appressed and semi-erect setae (Figure 16).

Mesosoma: Mesoscutum smooth, sculptured laterally, with very dense setae laterally. Mesoscutum 1.4 times as long as wide. Scutellum subspherical, strongly rugose with about 15 setae (Figure 17). Propodeum (Figure 18) extremely rugose. Upper and lower parts of propodeum with 5-6 long setae on each side. Fore wing (Figure 21) densely pubescent, with long lower marginal setae, longer than those on fore wing surface. Pterostigma triangular, 1.62 times as long as its width. Vein 2-1A sclerotized. Metacarpus absent. Secondfourth segments (Figure 19) of fore tarsus in dorsal view distinctly longer than wide (1.4-1.8 times as long as wide) and medium sized of apical bristles. Hind tibia medially and femur subbasally parallel-sided (Figure 20).

Metasoma: damaged.

Length: head and mesosoma combined about 1 mm; fore wing about 1.7 mm.

Coloration: General body color brown. Head brown. Mouthparts light-brown. Scape and pedicel brown with small yellow terminal part. F1 and F2 yellow, remaining parts of antennae brown. Mesosoma brown to light-brown. Legs yellow to light-brown.

Male: unknown.

Etymology.

The name of the new species refers to the very rugose propodeum and scutellum.
