Types condition – Holotype and paratypes are in good condition: holotype is glued on a card point by its right mesosoma side; paratypes also glued on card points either by right mesosomal side or by mesosternum or by coxae 2–3.

Type depositories – Holotype and three female + one male paratypes in Alexander Humboldt Institute, Villa de Leyva , Boyacá, Bogotá ( Colombia); two female paratypes are in Hungarian Natural History Museum, Budapest. Hym. Typ. Nos 12068–12069.

Etymology – The species name ”adjunctus” indicating its close similarity (adjuncta =

joining) to M. (C.) malcolmi Marsh.

Description of the female holotype – Body 2.1 mm long. Antenna slightly longer than body. Flagellomeres 1–2 equal in length, first flagellomere seven times as long as broad preapically (Fig. 1). Head in dorsal view transverse (Fig. 2), 1.7 times as broad as long, eye 1.3 times as long as temple, temple receded. Inner margin of eyes parallel. Head polished. – Mesosoma in lateral view 1.3 times as long as high, shiny, mesoscutum subshiny. Precoxal suture missing. Metanotum as in Fig. 111. Propodeum with a medio-longitudinal carina, laterally from it rugo-rugulose, posteriorly with a transverse carina (Fig. 3). Metanotum as in Fig. 111. Hind femur four times as long as broad distally (Fig. 4). – Fore wing: pterostigma 2.6 times as long as wide, issuing r just proximal of its midpoint; 2–SR one-fourth (or 1.3 times) longer than width of pterostigma (Fig. 5). – Sclerotized plate of first tergite broadening and that of second tergite as in Fig. 6. Ovipositor sheath as long as hind tarsomeres 2–3 combined. – Head and mesosoma black, metasoma blackish brown. Orbit rusty, palps yellow. Tegula and legs yellow, hind tibia and tarsis blackish fumous. Membranous part of tergites 1–2 dirty whitish, that of third light brownish. Wings hyaline, pterostigma and veins yellow.

Description of four female paratypes (nominate form) – Similar to the female holotype. Body 2–2.2 mm long. Head in dorsal view 1.7–1.8 times as broad as long, eye 1.3–1.5 times as long as temple. Hind femur 4.4–4.6 times as long as broad either (just) distally (Fig. 7) or medially (Fig. 4). Fore wing: pterostigma 2.3–2.6 times as long as wide.

Description of two female and one male paratypes (melanic form) – Similar to the nominate form except corporal colour: body blackish, membranous part of tergites 1–2 brown. Legs brownish yellow (1 f).

Host unknown.

Distribution: Colombia.

Taxonomic position – The new species, Mirax (Centistidea) adjunctus , is nearest to M. (C.) topali Papp ( PAPP 1993) considering their less broad head in dorsal view, relatively long ovipositor sheath and dark corporal groundcolour; the two species are distinguished by the features in the following key:

Figs 1–13. 1–7: Mirax (Centistidea) adjunctus sp. n. (female): 1 = flagellomeres 1–3, 2 = head in dorsal view, 3 = propodeum, 4 = hind femur (holotype), 5 = pterostigma and 2–SR of right fore wing, 6 = tergites 1–2, 7 = hind femur (paratype). – 8–10: Mirax (Centistidea) topali Papp : 8 = fla- gellomeres 1–3, 9 = head in dorsal view, 10 = hind femur. – 11–13: Mirax (Centistidea) malcolmi

Marsh: 11 = head in dorsal view, 12 = pterostigma and 2–SR of fore wing, 13 = tergites 1–2.

1 First flagellomere 1.3–1.4 times as long as second flagellomere (Fig. 8). Eye in dorsal view almost twice as long as temple, temple rounded (Fig. 9). Hind femur 3.3–4 times as long as broad, somewhat more broad medially (Fig. 10). Antenna yellow, apically brownish. fm: 1.8–1.9 mm. – Argentina M. (C.) topali Papp, 1993

– Flagellomeres 1–2 equal in length (Fig. 1). Eye in dorsal view 1.3–1.4 times as long as temple, temple receded (Fig. 2). Hind femur 4.4 to 4.6 times as long broad, somewhat less broad medially (Figs 4, 7). Scape and pedicel rusty brown, flagellum dark to blackish brown. f: 2–2.2 mm, m: 2.2 mm. – Colombia M. (C.) adjunctus sp. n.

The new species is also near to M. (C.) vertus sp. n., they distinguishing features are presented in the treatment of M. vertus .

On the basis of its original description and of named specimens (4 ff + 1 m det. J. Papp) M. (C.) malcolmi Marsh ( MArsh 1979) is also similar to M. (C.) adjunctus , they distinctions restrict to a few features, see key-couplet 10.
