Mirax (Centistidea) dilatus sp. n.
(Figs 30–37)
Material examined (2 ff) – Female holotype: Colombia, Boyacá SFF, Iguaque Qda. Carrizal, 5˚25’W / 73˚27’N, 3350 m, taken with Malaise trap, 21 January – 9 February 2001, leg. P. Reina (M 1247). Female paratype: Colombia, Boyacá SFF, Iguaque Cabaña Mamaramos m1, 5˚25’N / 73˚27’W, 2855 m, taken with Malaise trap, 23 May – 8 June 2000, P. Reina (M 146) .
Types condition – Holotype is in good condition: (1) glued on a card point by right metapleuron and middle coxa, (2) missing: left fore leg (except coxa), tarsomeres 2–5 of right fore leg, (3) hind pair of wings apically folded back. – Paratype also in good condition: (1) glued on a card point by right meso- and metapleuron, (2) missing: tarsomeres 4–5 of left middle and hind legs, pair of claws of right hind tarsus.
Types depositories – Holotype is deposited in the Alexander Humboldt Institute, Villa de Leyva , Boyacá, Bogota ( Colombia); paratype in Hungarian Natural History Museum, Hym. Typ. No. 12071
Etymology – The name ”dilatus” refers to the wide pterostigma (Figs 34, 37).
Description of the female holotype –Body 2.1 mm long. Antenna one-sixth longer than body, flagellomeres 1–2 equal in length, first flagellomere six times as long broad preapically (cf. Fig. 1). Head in dorsal view transverse (Fig. 30), 1.7 times as broad as long, eye 1.5 times as long as temple, temple rather receded. Eye in lateral view 0.85 times as broad as temple, i.e., temple almost 1.2 times as broad as eye and evenly broad beyond eye (Fig. 31, see arrows). Inner margin of eyes parallel (cf. Fig. 103, see arrows). Head polished. – Mesosoma in lateral view 1.5 times as long as high, polished. Mesoscutum dull, scutellum subshiny. Metanotum as in Fig. 112. Propodeum along medio-longitudinal carina rugulose with very short transverse carinulae, posteriorly with a transverse carina, otherwise polished (Fig. 32). Hind femur 3.5 times as long as broad medially (Fig. 33). – Fore wing: pterostigma wide, 2.3 times as long as wide, issuing r somewhat proximally from its midpoint, 2–SR somewhat shorter than width of pterostigma (Fig. 34). First discal cell long, 1–M 1.4 times as long as m–cu, 1–SR–M convex, one-sixth longer than 1–M and m–cu curved (Fig. 35). – First tergite as long as broad posteriorly, its sclerotized plate ”angularly” broadening, sclerotized plate of second tergite as in Fig. 36. Ovipositor sheath long, almost as long as hind tarsomeres 1–3 combined. – Antenna brown. Head and mesosoma testaceous, metasoma brownish black, legs yellow. Wings hyaline, pterostigma and veins yellow.
Deviating features of the female paratype – Body 2 mm long. Hind femur five times as long as broad medially. Fore wing: pterostigma 2.5 times as long as wide and issuing r somewhat proximally from its middle, 2–SR as long as width of pterostigma (Fig. 37).
Male and host unknown.
Distribution – Colombia.
Taxonomic position – The new species, Mirax (Centistidea) dilatus , is nearest to M. (C.) carinatus sp. n. considering their common features: body light coloured, receded temple in dorsal view and sclerotization of tergites 1–2; distinction between the two species is presented in key-couplet 9.
The new species is also near to M. (C.) insularis Muesebeck considering their yellow corporal colour and short 2–SR (i.e., not longer than width of pterostigma); the two species differ from each other by the features in the key:
1 Notaulix finely crenulated, extending to nearly anterior half of mesoscutum (Fig. 47). Eye in dorsal view twice as long as temple, temple receded, head in dorsal view 1.8 times as broad as long (Fig. 46). Hind femur 2.8–3 times as long as broad distally (Figs 49, 54). First flagellomere slightly longer than second flagellomere, flagellomeres 2–3 almost equal in length (Fig. 45). Fore wing: pterostigma 2.6 times as long as wide (Fig. 50). Hind half of metasoma brownish. f: 1.3–1.6 mm. – Dominica, Gua- deloupe M. (C.) insularis Muesebeck, 1937 View in CoL
– Notaulix not crenulated, restricted to declivous anterior part of mesoscutum. Eye in dorsal view 1.5 times as long as temple, temple rather receded, head in dorsal view 1.7 times as broad as long (Fig. 30). Hind femur 3.6 times as long as broad medially (Fig. 33). Flagellomeres 1–2 equal in length, third flagellomere somewhat shorter than second flagellomere (cf. Fig. 22 View Figs 14–29 ). Fore wing: pterostigma 2.3 times as long as wide (Fig. 34). Metasoma entirely brown. f: 2–2.1 mm. – Colombia M. (C.) dilatus sp. n.
