Mesocentrus crassipes SZÉPLIGETI, 1900 View in CoL : Természetrajzi Füzetek 23: 56 fm, type locality: “Friedrich-Wilhelmshafen” (= Madang) Papua New Guinea, female lectotype (and one male paralectotype in the Hungarian Natural History Museum, Budapest. – SHENEFELT 1969: 443, 1978: 1871 (literature up to 1969). VAN ACHTERBERG 1995a: 32 (redescription).

Remark. – The type-series (female lectotype and one male paralectotype) of this species was borrowed by Dr. A. AUSTIN (Adelaide) in 1989 and up to 2004 he had not returned it despite my repeated demand. Hence I could examine only the single female specimen from Australia (see subsequently).

Material examined (1 f). – One female: Australia, New South Wales, Kiola State Forest, taken with soil trap, 4 January 1979, Collector of the Australian Museum , Sydney. – The female specimen is deposited in the Department of Zoology , Hungarian Natural History Museum , Budapest .

Redescription of the female. – Body 3.1 mm, fore wing 2.7 mm long. Antenna with 17 antennomeres as long as head, mesosoma and tergites 1–2 combined. First flagellomere 2.1 times, penultimate flagellomere 1.75 times as long as broad, flagellum not attenuating. Antennal sockets a bit less that twice as far from each other as one socket from eye. – Head in dorsal view ( Fig. 12 View Figs 12–19 ) transverse, twice as broad as long, eye twice as long as temple, temple constricted, occiput excavated. OOL twice as long as POL, ocelli of average size. Eye in lateral view 2.2 times as high as wide, temple 0.8 times as wide as eye; temporal carina curved (i.e. not angular) towards occipital and hypostomal carinae ( Fig. 13 View Figs 12–19 ). Maxillary palp about one-fifth shorter than height of head. Malar space a bit longer than basal width of mandible. Head above rugulo-granulose, frons rugulose, face transversely rugulose, temple polished.

Mesosoma in lateral view twice as long as high. Precoxal suture granulose, mesopleuron polished. Middle lobe of mesoscutum rugulose, lateral lobes granulose. Propodeum areolate-rugose. – Fore femur thick, 2.3 times ( Fig. 14 View Figs 12–19 ), hind femur 2.9 times ( Fig. 15 View Figs 12–19 ) as long as broad medially. Claw of hind tarsus as in Fig. 16 View Figs 12–19 .

Fore wing ( Fig. 17 View Figs 12–19 ): Pterostigma three times as long as wide issuing r somewhat distally from its middle, r as long as width of pterostigma, second submarginal cell long, 3–SR 1.7 times as long as 2–SR, r 0.8 times as long as 2–SR, SR1 weakly arched and 1.5 times as long as 3–SR. First discal cell elongate, 1–SR–M twice as long as 1–M, 1–M 1.5 times as long as m–cu ( Fig. 18 View Figs 12–19 ).

First tergite ( Fig. 19 View Figs 12–19 ) moderately broadening posteriorly, 1.2 times as long as behind, longitudinally striate, interstriation uneven, subshiny. Second tergite wide trapeziform, 1.85 times as broad behind as long medially, almost entirely striate (striation somewhat less strong than that of first tergite); further tergites polished. Suture between tergites 2–3 straight, shallow, smooth. Ovipositor sheath in lateral view as long as tarsomeres 1–2 of hind leg.

Head and mesosoma testaceous, tergites rusty. Antenna testaceous to darkening brown, flagellomeres 10–14 yellowish. Prosoma brownish. Tegula and parategula yellow. Mesopleuron dark brown. Propodeum black, first tergite blackish. Fore leg yellow, middle and hind legs light testaceous, coxae and trochanters whitish, hind femur with a brown ring. Wings subhyaline, pterostigma brown with a pale yellow spot basally, veins brownish to light brown.

Host unknown.

Distribution: Australia (New South Wales), Papua New Guinea (Madang). 18 = first discal cell of fore wing, 19 = tergites 1–2

Mesocentrus crassipes SZÉPLIGETI is nearest to M. rutilus sp. n., their distinction is presented in the key at couplets 4(5)–5(4).

Remark. – See also SHENEFELT’ s (1969: 443) and VAN ACHTERBERG’ s (1995 a: 32, 194) redescription and figures of this species, their redescriptions cover several morphological features which are omitted here.
