Mirax (Centistidea) fuscus sp. n.

(Figs 38–44)

Material examined – Female holotype: Colombia , Santander, Virolin Costilla de Fara , 6˚6’N / 73˚13’W, 1800 m, taken with Malaise trap, 29–31 March 1999, leg. E. Gonzales (M 286). – Holotype is in good condition: glued on a card point by right mesosoma side. Holotype is deposited in Alexander Humboldt Institute, Villa de Leyvá, Boyacá, Bogota ( Colombia) .

Etymology – The species name ”fuscus” refers to the brown corporal colour.

Description of the female holotype – Body 1.8 mm long. Antenna slightly longer than body. First flagellomere one-fourth (1.3 times) longer than second flagellomere and 3.6 times as long as broad preapically (Fig. 38), penultimate flagellomere 2.4 times as long as broad. Head in dorsal view transverse (Fig. 39), twice as broad as long, eye twice as long as temple, temple receded. Inner margin of eyes parallel. Head polished. – Metanotum as in cf. Fig. 111. Propodeum along medio-longitudinal carina with fine transverse carinulae, posteriorly with a transverse carina as in Fig. 40. Hind femur thick, three times as long as broad medially (Fig. 41). – Fore wing: pterostigma 2.8 times as long as wide, issuing r from its midpoint, 2–SR 1.4 times as long as width of pterostigma, 1– R 1 0.25 times as long as length of pterostigma (Fig. 42). First discal cell fairly high, 1–M nearly 1.6 times as long as m–cu (Fig. 43), parallel nerv less distinct. – Sclerotized (brown) plate of first tergite wide spoon-form, that of second tergite fairly wide and ”angled” as in Fig. 44. Ovipositor sheath short, as long as second tarsomere of hind tarsus. – Scape and pedicel yellowish brown, flagellum brown. Body brown. Tegula light brown. Oral organs and legs yellow, hind leg with brown(ish) pattern. Wings hyaline, pterostigma brown, veins light brown.

Male and host unknown.

Distribution – Colombia.

Taxonomic position – The new species, Mirax (Centistidea) fuscus , is near to M. (C.) insularis Muesebeck viewing their receded temple in dorsal view, the two species are distinct by the features as follows:

1 Head in dorsal view 1.8 times as broad as long, temple slightly less receded (Fig. 46). Hind femur 2.8(–3) times as long as broad distally (Figs

49, 54). Fore wing: r less distinct, 2–SR as long as width of pterostigma

(Fig. 50). Ground colour of body yellow with light brownish to brown pattern. f: 1.3–1.6 mm. – Dominica, Guadeloupe

M. (C.) insularis Muesebeck, 1937

– Head in dorsal view twice as broad as long, temple receded (Fig. 39). Hind femur three times as long as broad medially (Fig. 41). Fore wing: r distinct, 2–SR 1.4 times as long as width of pterostigma (Fig. 42). Ground colour of body brown. f: 1.8 mm. – Colombia M. (C.) fuscus sp. n.
