R. Cave. – Condition of the types are good. Holotype: glued on a pointed card by its right meso- and metapleuron. Three female and one male paratypes: glued like the holotype, one female (collected 30 August 1995): left flagellum apically deficient (i.e. with 19 flagellomeres).

D e p o s i t o r y: Female holotype and two female + one male paratypes are deposited in the Zoologisk Museum, Lund; one female paratype in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 12023 .

E t y m o l o g y: The species name "subparallelus" of the new species refers to the weakly broadening first tergite ( Fig. 28 ).

D e s c r i p t i o n of the female holotype: Body 3.2 mm long. Antenna somewhat longer than body and with 26 antennomeres. First flagellomere 2.5 times, further flagellomeres shortening and attenuating so that penultimate flagellomere 1.8 times as long as broad. Head in dorsal view transverse (Fig. 20). twice as broad as long, eye slightly protruding and 1.3 times as long as temple, temple receded, occiput weakly excavated. Ocelli middle-sized, elliptic, near to each other. Eye in lateral view nearly round (Fig. 21), 1.3 times as high as wide, slightly wider than temple, temporal and occipital carina strong. Malar space a bit longer than basal width of mandible. Face twice as wide as high, inner margin of eyes parallel. Clypeus 3.3 times as wide as high, its ventral margin truncate. Distance between tentorial pits one-third longer than distance between pit and lowest point of eye. Head polished, face medially rugose.

Mesosoma in lateral view 1.5 times as long as high, polished. Pronope present, medially divided by a keel. Notaulix distinct, evenly deep, crenulated. Prepectal carina distinct. Precoxal suture crenulated, margin of mesopleuron also crenulated. Propodeum: areola basalis distinct, areolae smooth, at most rugulose-uneven, pair of spiracles lateromedially ( Fig. 25 ). Hind femur thin, five times as long as broad distally (Fig. 22). Hind pair of spurs short, shorter than fourth tarsomere. Basitarsus of hind leg as long as tarsomeres 2-3 combined.

Forewing as long as body. Pterostigma ( Fig. 26 ) 3.6 times as long as wide and issuing r from its middle, r somewhat shorter than half width of pterostigma. Second submarginal cell fairly large, 2-SR 1.3 times as long as r-m, 3-SR somewhat shorter than r-m and 0.6 times as long as 2-SR; SR1 straight, almost five times as long as 3-SR and reaching tip of wing. 2-R1 short, somehat longer than r and 1-R1 1.5 times as long as pterostigma. 1-SR (or petiole) of first discal cell short, 1-M twice as long as m-cu and 1.6 times as long as 1-SR-M; 1-Cu1 short, m-cu antefurcal ( Fig. 26 ). First subdiscal cell distally just open, i.e. CU1b amost missing ( Fig. 26 , see arrow). First and second anal veins (2A and a) present. Hind wing: M + Cu 1.5 times as long as 1-M, cu-a straight ( Fig. 27 ).

First tergite ( Fig. 28 ) long, less broadening posteriorly: 1.5 times as long as posteriorly, pair of spiracles before middle of tergite, pair of basal carinae short, scutum longitudinally rugo-rugulose. Tergites 2-3 transverse, third tergite somewhat longer than second tergite, together with further tergites polished. Ovipositor sheath long, as long as hind tibia + basitarsus combined.

Scape and pedicel brown, flagellum dark brown. Head, mesosoma and first tergite black, metasoma brown. Oral organs pale yellow. Tegula yellow. Mesoscutum with brownish suffusion. Coxae and trochanters whitish yellow, legs 1-2 brownish yellow, hind leg brown. Wings subhyaline, pterostigma and veins light brown.

D e s c r i p t i o n of the three female paratypes: Similar to the female holotype. Body 2.9-3 mm long. Antenna with 25 antennomeres. Head in dorsal view 2-2.2 times as broad as long. Forewing: r-m 1.3 times as long as 3-SR (1. Hind femur 4.5 times as long as broad distally (1). First tergite 1.7 times as long as broad posteriorly (1). Mesosoma dorsally with brownish suffusion. (1).

D e s c r i p t i o n of the male paratype: Similar to the female. Body 4 mm long. Antenna with 29 antennomeres. Head in dorsal view 2.1 times as broad as long. Hind femur 4.5 times as long as broad distally. First tergite 1.5 times as long as broad behind. Head and mesosoma black, tegula brown.

Host unknown.

D i s t r i b u t i o n: Honduras.

T a x o n o m i c p o s i t i o n: The new species, Topaldios subparallelus , is nearest to T. porrectus PAPP ( PAPP 1995: 111) , the two species are distinguished by the following features: 1 (2) Female: first tergite somewhat broader behind than long (Fig. 29), male: first tergite one-sixth longer than broad posteriorly (Fig. 30). Temple in dorsal view rounded (Fig. 23). Propodeum: areola basalis wide, its carination as in Fig. 31. Forewing: pterostigma issuing r clearly distally from its middle; 1-M (of discal cell) short, 0.7 times as long as 1-SR-M; first subdiscal cell distally closed (see arrow in Fig. 32); 1- R1 approaching tip of wing, 2-R1 somewhat longer than r (Fig. 32). Hind femur thick, 3.3 times as long as broad (Fig. 24). Legs reddish yellow.: 4.5 mm,: 4-4.5 mm. Argentina............................................................................... T. porrectus PAPP 1995 2 (1) Female and male: first tergite 1.5 times as long as broad posteriorly ( Fig. 28 ). Temple in dorsal view receded (Fig. 20).
