Mesocentrus reptus sp. n. m

( Figs 29–36 )

Material examined (1 m). – Male holotype: Papua New Guinea, Haus Copper Wau , Mt. Missim, 22–24 April 1965, leg. J. BALOGH et J. SZENT-IVÁNY. – Holotype is deposited in the Hungarian Natural History Museum (Department of Zoology) Budapest, Hym. Typ. No. 10703. – Holotype is in good condition: glued on a pointed card by its mesosternum, left antenna damaged (having only six flagellomeres), right middle tarsus missing .

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

Description of the male holotype. – Body 3.1 mm, fore wing 3 mm long. Antenna with 15 antennomeres (right antenna) as long as head, mesosoma and first tergite combined. First flagellomere four times, penultimate flagellomere 3.7 times as long as broad, flagellum attenuating distally. Antennal sockets twice as far from each other as one socket to eye. – Head in dorsal view ( Fig. 29 ) transverse, 1.85 times as broad as long, eye slightly protruding and nearly twice as long as temple, temple somewhat more rounded, occiput deeply excavated. OOL one-third longer than POL, ocelli large. Eye in lateral view 1.9 times as high as wide, temple 0.6 times as wide as eye, temporal carina angularly bent towards occipital as well as hypostomal carinae ( Fig. 30 , see arrows). Maxillary palp as long as height of head. Malar space just shorter than basal width of mandible. Head coriaceous; temple polished, its lower third uneven to subcoriaceous.

Mesosoma in lateral view twice as long as high. Precoxal suture rugulose with a few crenulae, mesopleuron polished. Mesoscutum granulose (a bit finer than that of head), postero-medially rugo-rugulose; scutellum polished. Propodeum rugose-scabrose, hind pair of areolae almost smooth and shiny. – Fore femur less thick, 2.8 times ( Fig. 31 ) and hind femur 3.1 times ( Fig. 32 ) as long as broad distally and medially, respectively. Claw of hind leg as in Fig. 33 .

Fore wing ( Fig. 34 ): Pterostigma 3.3 times as long as wide, issuing r distally from its middle, r just longer than width of pterostigma; second submarginal cell long, 3–SR twice as long as 2–SR, SR1 weakly arched and 1.4 times as long as 3–SR ( Fig. 34 ). First discal cell elongate, 1–M 1.9 times as long as m–cu ( Fig. 35 ).

discal cell of fore wing, 36 = tergites 1–2

First tergite ( Fig. 36 ) 1.6 times as long as broad behind and evenly broadening posteriorly, with four strong longitudinal striae, i.e. laterotergite visible in dorsal view (see arrows in Fig. 36 ), interstriation uneven and shiny. Second tergite long, trapeziform, 1.35 times as broad behind as long medially, suture between tergites 2–3 straight, subcrenulate. Second tergite with strong longitudinal striation, third and further tergites polished.

Body variably coloured. Head, mesoscutum and scutellum ochre; rest of mesosoma light brownish. Propodeum and first tergite dark rusty, rest of metasoma rusty. Scape and pedicel ochre, flagellum darkening ochre. Ocellar field black. Palpi light ochre. Legs yellow, fore and middle coxae and trochanters whitish. Wings faintly infuscate, pterostigma light brown, basally yellow; veins brownish.

Female and host unknown.

Distribution: Papua New Guinea.

The new species, Mesocentrus reptus , is nearest to M. baloghi sp. n., their distinction see in the key at couplets 13(14)–14(13).
