Aleiodes (Aleiodes) subcompressus sp. n.

( Figs 31–34 , 40–41)

Material examined – Female holotype: Korea, prov. Pyongyang , Samji-yon, Park, taken with lamp at night, 5 June 1985, leg. A. Vojnits et L. Zombori, loc. no. 1005. Holotype is in good condition: glued on card point by its mesosternum.

Type depository – Holotype is deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 12273.

Etymology – The new species received the name ”subcompressus” refering to the weakly and laterally compressed metasoma.

Description of the female holotype – Body 4.8 mm long. Antenna as long as body and with 35 antennomeres. First flagellomere 1.8 times as long as broad, further flagellomeres shortening and attenuating so that penultimate flagellomere twice as long as broad (Fig. 41). – Head in dorsal view transverse ( Fig. 31 ), 1.9 times as broad as long, eye somewhat protruding and 2.5 times as long as temple, temple receded. Ocelli large: POL shorter than greatest diameter of an ocellus (5:6). Eye in lateral view 1.7 times as high as wide and twice wider than gena ( Fig. 32 see arrows). Malar space as long as basal width of mandible. Face 1.7 times wider than high.

Mesosoma in lateral view 1.6 times as long as high. Notaulix weakly distinct. Mesosoma coriaceous. Propodeum rugulose with a medio-longitudinal carina. Hind femur 3.8 times as long as broad medially ( Fig. 33 ). Hind basitarsus as long as tarsomeres 2–3 combined.

Fore wing somewhat shorter than body: 4.2 mm long. Pterostigma 3.3 times as long as wide, issuing r proximally from its middle, r shorter than width of pterostigma (9:12), 3– SR 1.8–1.9 times longer than 2–SR, 2–SR 2.7 times longer than r, SR1 straight and reaching tip of wing (Fig. 40). 2–CU1 twice longer than 1–CU1.

First tergite somewhat longer than broad (40:35) and evenly broadening posteriorly, second tergite long, 1.3 times as long as broad and narrowing posteriorly ( Fig. 34 ). Metasoma beyond second tergite laterally weakly compressed. Third tergite quadrate: as long as broad basally. Tergites 1–3 longitadinally striated, interstriations rugulo-subrugulose, further tergites coriaceous. Ovipositor sheath short, as long as hind basitarsus.

Antenna proximo-distally testaceous to dark brown. Body testaceous. Palpi and tegula yellow. Legs ochre. Propodeum and first tergite with blackish suffusion. Wings subhyaline, pterostigma brownish, basally yellow. Veins brownish.

Male and host unknown.

Distribution – Korea.

Taxonomic position – The rogadine new species, Aleiodes (Aleiodes) subcompressus sp. n., is close to A. (A.) angustatus (Papp) considering their common features: long second tergite, less broadening first tergite, less transverse head in dorsal view and testaceous ground colour of body; the distinction between the two species is keyed:

1 (2) Metasoma laterally not compressed, dorsally broadening posteriorly ( Fig. 35 ). Hind femur thin, 6–7 times as long as broad distally ( Fig. 36 ). Second tergite somewhat longer than broad basally (35:32) and broadening posteriorly. Third tergite transverse, clearly twice as broad basally as long medially, suture and its crenulation distinct between tergites 2–3 ( Fig. 35 ). Eye in lateral view 1.6 times as high as wide and 1.5 to 1.3 times wider than gena ( Fig. 37 see arrows). Head in dorsal view: eye slightly less large, temple less receded ( Fig. 38 ). Antenna with 44–49 antennomeres. Pterostigma yellow. f: 7–7.2 mm. – Mongolia Aleiodes (Aleiodes) angustatus ( Papp, 1971)

2 (1) Metasoma postero-laterally weakly compressed, dorsally narrowing posteriorly ( Fig. 34 ). Hind femur less thin, 3.8 times as long as broad medially ( Fig. 33 ). Second tergite 1.3 times longer than broad behind and narrowing posteriorly. Third tergite as long as broad basally, suture missing between tergites 2–3 ( Fig. 34 ). Eye in lateral view 1.7 times as high as wide and twice wider than gena ( Fig. 32 ). Head in dorsal view: eye slightly larger, temple receded ( Fig. 31 ). Antenna with 35 antennomeres. Pterostigma brownish with yellow basal third. f: 4.8 mm. – Korea Aleiodes (Aleiodes) subcompressus sp. n.

The new secies is also close to A. (A.) pallidator (Thunberg) considering their common traits: receded temple in dorsal view ( Figs 31 , 43), posteriorly distinctly broadening first tergite ( Figs 34 , 42) and testaceous coloured body. Their distinctive features are as follows:

1 (2) Second tergite transverse, 1.3 times broader posteriorly than long, broadening backwards (Fig. 42). Metasoma not compressed laterally, broadening posteriorly (cf. Fig. 35 ). Gena in lateral view narrow: eye four times wider than gena ( Fig. 39 see arrows). Head in dorsal view: eye large and 3.5 times longer than temple, temple straightly receded (Fig. 43). Hind femur broad, 3.5–3.6 times as long as broad (Fig. 44). Penultimate flagellomere 2.5–2.6 times as long as broad (Fig. 45). f: 4.5–6 mm. – Holarctic region Aleiodes (Aleiodes) pallidator (Thunberg, 1822)

2 (1) Second tergite long, 1.3 times longer than broad posteriorly, narrowing backwards ( Fig. 34 ). Metasoma weakly compressed postero-laterally, narrowing posteriorly ( Fig. 34 ). Gena in lateral view less narrow: eye twice wider than gena ( Fig. 32 see arrows). Head in dorsal view: eye less large and 2.5 times longer than temple, temple rounded receded ( Fig. 31 ). Hind femur less broad, 3.8 times as long as broad ( Fig. 33 ). Penultimate flagellomere twice as long as broad (Fig. 41). f: 4.5 mm. – Korea Aleiodes (Aleiodes) subcompressus sp. n.
