Protodacnusa cubiceps sp. n. m

( Figs 78–82 , 87–88 )

Material examined (1 m). – Male holotype: Mongolia, Central aimak, SO von Somon Bajazogt, 1600 m, 11 Juni 1966, leg. Z. KASZAB (loc. no. 519) .

Holotype is deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 10728.

Holotype is in good condition: right antenna apically damaged, i.e. with 22 antennomeres; hind pair of wings distally somewhat shrivelled; glued on a pointed card by its mesosternum between coxae 1 and 2.

Etymology. – The species name “cubiceps ” refers to the cubic form of the head in dorsal view.

Description of the male holotype. – Body 3.3 mm long. Left antenna about as long as head, mesosoma and first tergite combined and with 27 antennomeres. First flagellomere 2.6 times and penultimate flagellomere 1.5 times as long as broad. – Head in dorsal view ( Fig. 78 ) less transverse, 1.6 times as broad as long, temple 1.8 times length of eye, occiput hardly excavated. Ocelli small, elliptic, OOL three times as long as POL. Head 1.5 times as broad as mesoscutum between tegulae. Eye in lateral view twice as high as wide, temple also twice wider than eye, vertex high ( Fig. 79 ). Mandible 1.3 times as long as broad between upper and lower teeth, upper tooth strong and fairly long ( Fig. 80 ). Tentorial pit not reaching eye. Head polished.

Mesosoma in lateral view 1.4 times as long as high. Mesoscutum, scutellum and mesopleuron polished. Precoxal suture long, reaching anterior margin of mesopleuron, narrow and finely crenulate. Pronotum uneven with rugulose-subrugulose elements, pronope present. Propodeum evenly rugose. – Hind femur 4.2 times as long as broad medially ( Fig. 81 ). Hind tibia and tarsus equal in length.

Fore wing somewhat shorter than length of body. Pterostigma ( Fig. 87 ) cuneiform, eight times as long as wide, issuing r clearly proximally from its middle; r longer than width of pterostigma but shorter than length of pterostigma between its basal end and emitting point of r; 1–R1 half as long as pterostigma; marginal cell ending before tip of wing. Subdiscal cell distally open, i.e. CU1b missing ( Fig. 82 ).

First tergite ( Fig. 88 ) broad, 1.2 times as long as broad behind, beyond pair of spiracles subparallel-sided, pair of converging keels merging into rugosity, i.e. tergite evenly rugose. Further tergites polished. Third tergite almost 1.4 times longer than second tergite, border between them hardly distinct.

Ground colour of body black. Mandible rusty, palpi brownish yellow. Scape, pedicel and flagellomeres 1–2 brownish, flagellum blackish brown. Tegula black, parategula brown. Tergites 3–4 with faint brownish suffusion. Legs 1–2 brownish yellow. Hind leg: coxa black, trochanters and femur rusty brown, tibia yellowish brown and distally dark fumous, tarsus also fumous. Wings hyaline, pterostigma and veins opaque light brownish-greyish.

Female and host unknown.

Distribution: Mongolia.

The new species, Protodacnusa cubiceps , is nearest to P. amurensis (TELEN-

GA), the two species are distinguished by the features keyed:

1 (2) First tergite as long as broad behind, posteriorly finely striated ( Fig. 89 ). Upper tooth of male mandible less strong and pointed ( Fig. 83 ), that of female as in Fig. 84 . Head in dorsal view between temples clearly (m, Fig. 85 ) and less clearly (f, Fig. 86 ) broader than between eyes. Pterostigma parallel-sided

(m, Fig. 90 ) and cuneiform (f, Fig. 91 ), six times as long as wide, 1–R1 0.3

times as long as pterostigma ( Figs 90–91 ). Scape and tegula yellow. m:

2.8–3.2 mm, f: 3 mm. – Asiatic Russia (Amur Region), Mongolia

P. amurensis ( TELENGA, 1934)

2 (1) First tergite 1.2 times as long as broad behind, rugose ( Fig. 88 ). Upper tooth of mandible strong and less pointed ( Fig. 80 ). Head in dorsal view between temples and eyes almost equal in breadth ( Fig. 78 ). Pterostigma cuneiform, eight times as long as wide, 1–R1 half as long as pterostigma ( Fig. 87 ). Scape brown, tegula black. m: 3.3 mm. – Mongolia P. cubiceps sp. n.
