Protodacnusa effunda sp. n. f

( Figs 92–98 )

Material examined (1 f). – Female holotype: Mongolia, Chentej aimak, Čandagan tal, 40 km O von Somon Žargaltchaan, 1300 m, 28 August 1965, leg. Z. KASZAB (loc. no. 316) .

Holotype is deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 10729.

Holotype is in good condition: right three legs less to hardly visible owing to their mounting, base of right fore wing sticked to femora 1–2; glued on a pointed card by its mesosternum.

Etymology. – The species name “effunda ” refers to the strongly broadening first tergite.

Description of the female holotype. – Body short, 1.4 mm long. Antenna as long as body and with 15 antennomeres. First flagellomere five times and penultimate flagellomere twice as long as broad. – Head in dorsal view ( Fig. 92 ) transverse, 1.8 times as broad as long, temple 1.4 times length of eye, occiput excavated. Ocelli small, elliptic, far from each other, OOL 1.5 times as long as POL. Head 1.7 times as broad as mesoscutum between tegulae. Eye in lateral view 2.1 times as high as wide, temple also 2.1 times as wide as eye and ventrally somewhat narrowing ( Fig. 93 , see arrows). Mandible just broader between upper and lower teeth than its length, upper tooth strong ( Fig. 94 ). Tentorial pit not reaching eye. Head polished, face dispersely hairpointed.

subdiscal cell of right fore wing, 102 = hind femur

Mesosoma in lateral view stout, 1.25 times as long as high, polished. Pronotum anteriorly uneven, pronope present. Precoxal suture distinct, smooth. Propodeum anteriorly with very dense hairpunctures. – Hind femur four times as long as broad medially ( Fig. 95 ). Hind tibia and tarsus equal in length.

Fore wing as long as body. Pterostigma ( Fig. 96 ) less wide, subcuneiform: parallel-sided and narrowing only at its distal fourth, ten times as long as wide and issuing r near to its basal end of pterostigma; r as long as width of pterostigma; 1–R1 short, 0.34 times length of pterostigma, i.e. marginal cell ending far before tip of wing; 3–SR + SR1 bent as in Fig. 96 . Subdiscal cell distally open, i.e. CU1b missing ( Fig. 97 ).

First tergite ( Fig. 98 ) strongly broadening posteriorly, somewhat (1.2 times) broader behind than long, evenly broadening from base to its end, basally somewhat less than half as broad as apically; converging pair of keels merging into rugosity, i.e. tergite evenly rugose. Further tergites polished. Third tergite somewhat longer than second tergite, border between them almost indistinct ( Fig. 98 ). Ovipositor sheath concealed.

Ground colour of body black. Scape and pedicel dark rusty, flagellum blackish. Mandible brownish yellow, palpi brown. Tegula dark brown, parategula light brown. Tergites (except black first tergite) with faint brownish tint. Legs brown to dark brown, hind coxa black, femora 1–2 apically and tibiae 1–2 proximally pale brownish. Wings hyaline, pterostigma and veins opaque light brownish-greyish.

The new species, Protodacnusa effunda , is nearest to P. ruthei GRIFFITHS considering their open subdiscal cell and more or less broadening first tergite; the two species are distinguished by the following features:

1 (2) First tergite less broadening posteriorly, 1.5–1.7 times as long as broad behind ( Fig. 99 ). Antenna with 21–26 antennomeres. Pterostigma wide, eight times as long as wide, marginal cell long, i.e. ending somewhat nearer to tip of wing ( Fig. 100 ). Subdiscal cell open as in Fig. 101 . Hind femur five times as long as broad medially, parallel-sided ( Fig. 102 ). Mandible rusty brown, tegula black. f: 2.5–3 mm. – Europe (three countries), Mongolia

P. ruthei GRIFFITHS, 1964

2 (1) First tergite strongly broadening posteriorly, somewhat (1.2 times) broader behind than long ( Fig. 98 ). Antenna with 15 antennomeres. Pterostigma less wide, ten times as long as wide, marginal cell short, i.e. ending somewhat less near to tip of wing ( Fig. 96 ). Subdiscal cell open distally as in Fig. 101 . Hind femur four times as long as broad medially ( Fig. 102 ). Mandible brownish yellow, tegula dark brown. f: 1.4 mm. – Mongolia P. effunda sp. n.
