Mirax (Centistidea) carinatus sp. n.
( Figs 22–29 View Figs 14–29 )
Material examined (2 ff) – Female holotype: Colombia, Magdalena PNN, Tayro- na Cañaveral , 30 m, 11˚20’N / 74˚2’W, taken with Malaise trap, 28 July – 14 August 2000, leg. Henriquez (M 565) . One female paratype: Colombia, Amazonas PNN, Amacayacu Matamata , 150 m, 3˚23’S / 70˚6’W, taken with Malaise trap, 20–27 December 2000, leg. A. Parente (M 1119).
Types condition – The two type specimens glued on a card points, holotype by mesosternum, coxae 2–3 and anterior half of sternites; paratype by right side of mesosoma, metasoma strongly creased.
Types depositories – Holotype is deposited in Alexander Humboldt Institute, Villa de Leyva , Boyacá, Bogotá ( Colombia); paratype in Hungarian Natural History Museum, Budapest, Hym. Typ. No. 12070.
Etymology – The species name refers to the strong carination of the propodeum ( Fig. 25 View Figs 14–29 ).
Description of the female holotype – Body 2.2 mm long. Antenna somewhat longer than body. Flagellomeres 1–2 equal in length, first flagellomere 6.2 times as long as broad preapically ( Fig. 22 View Figs 14–29 ). Head in dorsal view transverse ( Fig. 23 View Figs 14–29 ), 1.9 times as broad as long, eye almost twice as long as temple, temple receded. Eye in lateral view 1.25 times as broad as temple, i.e. temple 0.7 times as broad as eye, temple beyond eye evenly broad ( Fig. 24 View Figs 14–29 ). Inner margin of eyes parallel. Head polished. – Mesosoma in lateral view 1.5 times as long as high, polished. Metanotum as in cf. Fig. 111. Propodeum near to hind margin with a transverse carina, along strong medio-longitudinal carina finely rugulose with short transverse carinulae ( Fig. 25 View Figs 14–29 ). Hind femur 4.4 times as long as broad distally ( Fig. 26 View Figs 14–29 ). – Fore wing: pterostigma three times as long as wide, issuing r distally from its midpoint, 2–SR almost 1.4 times as long as width of pterostigma ( Fig. 27 View Figs 14–29 ). First discal cell short, 1–M 1.5 times as long as m–cu, 1–SR–M just concave and m–cu straight ( Fig. 28 View Figs 14–29 ). – First tergite somewhat longer than broad posteriorly, its sclerotized plate spoon-shaped: anterior linear part longer than posterior broadening part, sclerotized medio-linear form of second tergite long as in Fig. 29 View Figs 14–29 . Ovipositor sheath somewhat shorter than hind basitarsus. – Scape and pedicel light brownish, flagellum black, ultimate five flagellomeres straw yellow. Head and mesosoma light brownish, tergites 1–2 yellow, rest of tergites brownish black. Tegula and legs yellow. Wings subhyaline (very faintly brownish fumous), pterostigma and veins yellowish-brownish.
Deviating features of the female paratype – Body 2.1 mm long. Head in dorsal view 1.85 times as broad as long, eye nearly 1.7 times as long as temple. Hind femur four times as long as broad medially (cf. Fig. 4). Fore wing: pterostigma 3.3 times as long as wide.
Male and host unknown.
Distribution – Colombia.
Taxonomic position – The new species, Mirax (Centistidea) carinatus is nearest to M. (C.) striatus (Penteado-Dias) (PenteAdo- DiAs 1999) considering their common features: colour pattern of body, venation of wings and short notaulix; the differences between them are as follows:
1 Eye in dorsal view about as long as temple (Fig. 8 in PenteAdo- DiAs 1999:193). First flagellomere somewhat longer than second flagellomere (Fig. 7 l. c.). Occiput and third tergite striated (Figs 8 and 11 l. c.). Propodeum posteriorly without transverse carina. Sclerotized plate of first tergite: linear part much shorter than broadening part (Fig. 11 l. c.). Antenna brownish, basally somewhat paler. f: 1.6 mm. – Brazil
(C.) striatus (Penteado-Dias, 1999)
– Eye in dorsal view almost twice as long as temple ( Fig. 23 View Figs 14–29 ). First flagellomere as long as second flagellomere ( Fig. 22 View Figs 14–29 ). Occiput and third tergite smooth. Propodeum posteriorly with transverse carina ( Fig. 25 View Figs 14–29 ). Sclerotized plate of first tergite: anterior linear part longer than posterior broadening part ( Fig. 29 View Figs 14–29 ). Flagellum black, ultimate 5(–6) flagellomeres straw yellow. f: 2.1–2.2 mm. – Colombia M. (C.) carinatus sp. n.
