Protodacnusa meriva sp. n. f

( Figs 83–90 )

Material examined (3 f). – Female holotype: Mongolia, Central aimak, Tosgoni ovoo, 10 km N von Ulan –Baator, 1700–1900 m, 23–24 Juli 1967, leg. KASZAB (loc. no. 926a). – One female paratype: Mongolia, Zavchan aimak, 24 km O von Somon Songino, 2000 m, 12 Juli 1968, leg. KASZAB (loc. no. 1095). – One female paratype: Mongolia, Zavchan aimak, Choit chunch, 26 km ONO vom See Telmen nuur, 2150 m, 13 Juli 1968, leg. KASZAB (loc. no. 1104) .

Holotype and two paratypes are deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. Nos 10697 (holotype) and 10698–10699 (paratypes).

Holotype is in good condition: glued on a pointed card by its right mesopleuron. Two paratypes are in fairly good condition: one paratype (No. 10698) glued on a pointed card by its mesosternum, left middle and hind legs missing; one paratype (No. 10699) glued on a pointed card by its right side, right fore and middle legs almost invisible owing to the mounting.

Etymology. – The species name “meriva ” is a phantasy name.

Description of the female holotype. – Body 1.8 mm long. Antenna about as long as head and mesosoma combined and with 19 antennomeres. First flagellomere three times and penultimate flagellomere 1.3 times as long as broad, flagellum distally thickening. – Head in dorsal view ( Fig. 83 ) subcubic, 1.5 times as broad between temples as long, i.e. head behind eyes swollen; temple 1.6 times longer than eye, occiput weakly excavated. OOL clearly three times as long as POL. Mandible as in Fig. 84 , second tooth spiky. Head polished.

Mesosoma in lateral view 1.7 times as long as high. Notaulix less distinct and restricted to declivous part of mesoscutum. Mesoscutum hairy except hind lateral two sides, its hind fovea linear and faintly distinct. Precoxal suture absent. Propodeum smooth, along hind margin rugulo-uneven. – Hind femur 4.1 times as long as broad medially ( Fig. 85 ). Hind basitarsus as long as tarsomeres 2–3 combined.

Fore wing somewhat longer than body. Pterostigma ( Fig. 86 ) elongate and parallel-sided, 6.5 times as long as wide and issuing r from its proximal third; r as long as width of pterostigma, 3–SR + SR1 ending far before tip of wing, 1–R1 half as long as pterostigma. Vein m–cu antefurcal, CU1b of subdiscal cell present, i.e. cell distally closed.

First tegite ( Fig. 87 ) 1.3 times as long as broad behind, evenly broadening posteriorly, pair of spiracles before middle of tergite, pair of carinae extending up to spiracles, tergite longitudinally rugulose. Further tergites polished. Ovipositor sheath in lateral view as long as hind tarsus, and upcurved. ( Fig. 88 ).

Body black with faint brownish tint. Scape dark brown, flagellum black. Mandible yellow, teeth brown. Palpi light brown. Legs brownish black with light coloured pattern. Wings hyaline, pterostigma and veins brown.

Description of the two female paratypes. – Similar to the female holotype. Body 2–2.1 mm long. Antenna with 19 and 21 antennomeres. Hind femur 3.6 times as long as broad medially ( Fig. 89 ). First tergite ( Fig. 90 ) more broadening behind, 1.1 times as long as broad behind. Ovipositor sheath in lateral view as long as hind basitarsus (1 f).

Male and host unknown.

Distribution: Mongolia.

The new species, Protodacnusa meriva , is nearest to P.orientalis TOBIAS, 1998 ( Russia: Far East Maritime Territory) and to P. aridula (THOMSON, 1895) (Europe). The distinction between P. meriva and P. orientalis is presented subsequently (the distinction of the latter species is restricted to its short description, cf. TOBIAS 1998: 315–316, i.e. I do not know P. orientalis in nature):

1 (2) Male: Pterostigma four times as long as wide, r clearly shorter than width of pterostigma (Fig. 119: 9 in TOBIAS 1998: 313). Second tooth of mandible less spiky (Fig. 119: 8 l. c.). Second tergite with two rows of piles. Scape, palpi and legs brownish yellow. m: 3.5 mm P. orientalis TOBIAS

2 (1) Female: Pterostigma 6–7 times as long as wide, r as long as width of pterostigma ( Fig. 86 ). Second tooth of mandible spiky ( Fig. 84 ). Second tergite bare. Scape dark brown, palpi light brown and legs brownish black. f: 1.8–2.1 mm P. meriva sp. n.
