Dacnusa (Aphanta) kaszabi View in CoL sp. n. fm
( Figs 34–40 View Figs 34–43 , 44 View Figs 44–50 )
Material examined (2f + 1 m). – Female holotype and one female + one male paratypes: Mongolia, Uvs aimak, S Rand des Sees Örög nuur, 1500 m, 28 VI – 5 VII 1968, leg. Z. KASZAB (loc. no. 1036). – Holotype and two paratypes (1 f + 1 m) are deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. Nos 10666 (holotype) and 10667–10668 (paratypes).
Holotype is in good condition: specimen glued on a pointed card by its left mesosomal side, left legs more or less immerged in glue. Two paratypes are mounted similar to the holotype.
Etymology. – The new species is dedicated to Dr. ZOLTÁN KASZAB (1915–1986), collector of the new species and world-wide known explorer of the insect etc. fauna of Mongolia.
Description of the female holotype. – Body 2.1 mm long. Antenna somewhat longer than body and with 23 antennomeres. Flagellum filiform, first flagellomere 1.4 times as long as second flagellomere, further flagellomeres gradually shortening so that penultimate flagellomere twice as long as broad. – Head in dorsal view ( Fig. 34 View Figs 34–43 ) twice as broad as long, eye hardly longer than temple, temple rounded. OOL 2.3 times as long as POL. Eye in lateral view 1.5 times as high as wide, temple beyond eye 0.8 times as wide as eye. Mandible with three teeth, middle tooth spiky ( Fig. 35 View Figs 34–43 ). Head polished, face laterally uneven.
Mesosoma in lateral view 1.2 times as long as high. Notaulix shallow and reaching middle of mesoscutum, hind middle fovea short linear and deep. Precoxal suture narrow, finely crenulate. Propodeum rugose, pubescent. Metapleuron densely hair-punctured, less pubescent. – Hind femur ( Fig. 36 View Figs 34–43 ) five times as long as broad distally. Hind tarsus one-fifth shorter than hind tibia.
Fore wing somewhat longer than body. Pterostigma ( Fig. 37 View Figs 34–43 ) cuneiform, five times as long as wide, issuing r from its proximal fourth. Vein 1–SR–M missing (subgeneric feature), r as long as width of pterostigma, 3–SR + SR1 bent and ending fairly far before tip of wing, 1–R1 as long as length of pterostigma. First subdiscal cell quadrate, 3–CU1 + CU1b relatively thick ( Fig. 37 View Figs 34–43 ).
First tergite ( Fig. 38 View Figs 34–43 ) a bit longer than broad behind, evenly broadening posteriorly, pair of spiracles just before middle of tergite, pair of keels reaching middle of tergite; hind half of tergite rather longitudinally rugose, further tergites polished. Third tergite almost one-third longer than second tergite ( Fig. 38 View Figs 34–43 ). Ovipositor sheath short, in lateral view half as long as hind basitarsus ( Fig. 39 View Figs 34–43 ).
Scape and pedicel light brown, flagellum brown. Head dark brown, clypeus brown, mandible yellow, palpi pale yellow. Mesosoma brownish black, tegula dark brown, parategula light brown. Metasoma brown, tergite dark brown. Legs yellow with faint brownish suffusion. Wings hyaline, pterostigma and veins yellowish brown.
Description of the two paratypes (1 f + 1 m). – Similar to the female holotype. Body 2 mm long. Antenna with 22 antennomeres. Temple of male slightly swollen beyond eye ( Fig. 40 View Figs 34–43 ). Male: first tergite less broadening posteriorly; pterostigma wide, 2.8 times as long as wide proximally, 1–R1 just shorter than pterostigma ( Fig. 44 View Figs 44–50 ), pterostigma dark brown; head and mesosoma also dark brown.
Host unknown.
Distribution: Mongolia.
The new species, Dacnusa (Aphanta) kaszabi , is nearest to D. (A.) sasakawai TAKADA, 1977 ( Japan, Russia: Far East Maritime Territory and European part, Hungary), the series (2 f + 1 m) of the new species is compared to the pair of the paratypes (1 f + 1 m) housed in the Hungarian Natural History Museum purchased by exchange (and redescribed by FISCHER 1994: 260):
1 (2) Head in dorsal view ( Fig. 41 View Figs 34–43 ) 1.8 times as broad as long, temple somewhat less rounded. First tergite beyond pair of spiracles parallel-sided ( Fig. 42 View Figs 34–43 ).
TAKADA: 41 = female head in dorsal view, 42 = tergites 1–3, 43 = mandible
Middle tooth of mandible less spiky ( Fig. 43 View Figs 34–43 ). Female: pterostigma eight times as long as wide and parallel-sided ( Fig. 45 View Figs 44–50 ). Male: pterostigma less narrowing distally ( Fig. 46 View Figs 44–50 ). Female + male: SR1 concave, 1–R1 shorter than length of pterostigma. Legs yellow. f: 1.5–1.7 mm, m: 1.3–1.5 mm
2 (1) Head in dorsal view ( Fig. 34 View Figs 34–43 ) twice as broad as long, temple somewhat more rounded. First tergite evenly broadening posteriorly ( Fig. 38 View Figs 34–43 ). Middle tooth of mandible spiky ( Fig. 35 View Figs 34–43 ). Female: pterostigma 5–5.5 times as long as wide and narrowing distally ( Fig. 37 View Figs 34–43 ). Male: pterostigma narrowing distally ( Fig. 44 View Figs 44–50 ). Female + male: SR1 convex, 1–R1 almost as long as length of pterostigma. Legs yellow with faint brownish suffusion. fm: 2–2.1 mm
D. (A.) kaszabi sp. n.
The new species is related to D. (A.) hospita (FÖRSTER, 1862) (Europe) considering the evenly broadening first tergite of the two species, however, they are distinct by the features keyed:
1 (2) First tergite less broadening posteriorly, 1.3 times as long as broad behind ( Fig. 47 View Figs 44–50 ). Temple of female in dorsal view rounded ( Fig. 48 View Figs 44–50 ). Pterostigma of female subparallel-sided, six times as long as wide, 3–SR + SR1 curved at its middle ( Fig. 49 View Figs 44–50 ). Mandible with pointed teeth 1 and 3 ( Fig. 50 View Figs 44–50 ). Metasoma black, tergites 2–3 brownish. fm: 1.8–1.9 mm D. (A.) hospita (FÖRSTER)
2 (1) First tergite more broadening posteriorly, a bit longer than broad behind ( Fig. View Figs 34–43
38). Temple of female in dorsal view more rounded ( Fig. 34 View Figs 34–43 ), that of male somewhat swollen ( Fig. 40 View Figs 34–43 ). Pterostigma of female narrowing distally, five times as long as wide ( Fig. 37 View Figs 34–43 ). Mandible with rounded teeth 1 and 3 ( Fig. View Figs 34–43
35). Metasoma brown, first tergite dark brown. fm: 2–2.1 mm
