Mesocentrus baloghi sp. n. m

( Figs 4–11 )

Material examined (1 m). – Male holotype: Australia, New South Wales, environment Murvillumbach , 7 March 1965, leg. J. BALOGH. – Holotype is deposited in the Australian National Insect Collection, Canberra. – Holotype is in fairly good condition: glued on a pointed card by its mesosternum, right antenna damaged (having only four flagellomeres), hind pair of wings and tarsomeres 2–5 of left hind leg missing .

Etymology. – The new species is dedicated to the late Prof. Dr. JÁNOS BALOGH (1913–2002), zoologist and naturalist, explorer of the nature of Australia and Oceania, and the collector of the holotype specimen.

Description of the male holotype. – Body 3.6 mm, fore wing 3 mm long. Antenna with 16 antennomeres as long as head and mesosoma combined. First flagellomere 4.5 times, penultimate flagellomere 4.3 times as long as broad, flagellum attenuating distally. Distance between antennal sockets a bit greater than that between socket and eye. – Head in dorsal view ( Fig. 4 ) 1.66 times as broad as long, eye somewhat protruding and 1.5 times as long as temple, temple rounded, occiput excavated. OOL twice the length of POL. Eye in lateral view 1.9 times as high as wide, temple 0.8 times as wide as eye, temporal carina bent angularly towards occipital and hypostomal carinae ( Fig. 5 , see arrows). Maxillary palp somewhat longer than height of head. Malar space 0.8 times the basal width of mandible. Head coriaceous, frons with transverse rugulosity, temple polished.

tal part of right fore wing, 10 = first discal cell of fore wing, 11 = tergites 1–2

Mesosoma in lateral view twice its height. Precoxal suture crenulate, mesopleuron finely coriaceous and matt. Mesoscutum and scutellum granulose, propodeum rugulose. – Fore femur less thick, three times ( Fig. 6 ), hind femur 3.6 times ( Fig.7 ) as long as broad medially and proximally, respectively. Claw of hind tarsus as in Fig. 8 .

Fore wing ( Fig. 9 ): Pterostigma 3.6 times as long as wide, issuing r just distally from its middle, r a bit longer than width of pterostigma. Second submarginal cell less long, 3–SR 1.4 times as long as 2–SR, SR1 arched and nearly twice as long as 3–SR. First discal cell elongate, 1–M 1.4 times the length of m-cu ( Fig. 10 ).

First tergite ( Fig. 11 ) 1.3 times as long as broad behind and evenly broadening posteriorly, longitudinally striate, interstriations subshiny, laterotergite in dorsal view visible (see arrows in Fig. 11 ). Second tergite long, trapeziform, 1.3 times as broad behind as long medially, suture between tergites 2–3 faintly convex; second tergite and anterior three-fourths of third tergite with longitudinal striation (similar to that of first tergite). Tergites 4–5 with fine transverse substriation.

Ground colour of body testaceous. Face and clypeus yellow. Oral parts, palpi and cheek straw yellow. Tegula ochre yellow. Mesopleuron above, fore margin of metapleuron, propodeum laterally brownish; keel of laterotergite blackish. Antenna weakly darkening yellowish to brownish yellow. Legs pale yellow; hind coxa almost entirely, hind femur medially and hind tibia distally brownish to brown. Wing faintly infuscate. Pterostigma yellow, its lower part brownish, veins also brownish.

Female and host unknown.

Distribution: Australia (New South Wales).

The new species, Mesocentrus baloghi , is nearest to M. reptus sp. n., their distinction see in the key at couplets 15(16) – 16(15). – The distinction between M. baloghi and M. gilvus sp. n. is presented at the latter species.
