(Figs 45–54)

Mirax insularis Muesebeck, 1937: 139 fm, type locality: ” Guadeloupe, West-Indies”, female holotype (and female + male paratypes) in The Natural History Museum (London), female and male paratypes in The University, Puerto Rico (San Juan), one female and one male paratypes in Hungarian Natural History Museum, Budapest (by exchange, examined). – Shenefelt 1973: 677 (literature up to 1958). PenteAdo- DiAs 1999: 192 (in Note).

Material examined (1 f + 1 m paratypes and 1 f: all three specimens in Museum Budapest) – 1 m and 1 f paratypes (Hym. Typ. Nos 11676–11677): Dominica, 1936 (f) and 12 July 1936 (m), ex Leucoptera coffella Guérin , leg. et educ. F. Sein, Jr. 1 f: Dominica, Ridgefield, November 1963, leg. F. Bennett (No. 646) .

Additional features to the original description – f. Body 1.5–1.7 mm long. First flagellomere slightly (1.1 times) longer than second flagellomere, first flagellomere four times as long as broad preapically (Fig. 45), penultimate flagellomere three times as long as broad. Head in dorsal view 1.8 times as broad as long, eye twice as long as temple, temple receded (Fig. 46). Inner margin of eyes parallel (cf. Fig. 103). Head dull. – Mesosoma in lateral view 1.6 times as long as high, dull. Notaulix shallowing, finely crenulate-subcrenulated and extending to anterior half of mesoscutum (i.e. pair of notaulices not meeting posteriorly as in Fig. 47). Precoxal suture short, crenulated. Metanotum as in cf. Fig. 111. Propodeum with transverse carinulates and rugulae (Fig. 48). Hind femur thick, 2.8–3 times as long as broad distally (Figs 49, 54). Claw as in Fig. 110. – Fore wing: pterostigma 2.6–2.8 times as long as wide and issuing r from its middle, 2–SR as long as width of pterostigma (Fig. 50). First discal cell less high, 1–M 1.25 times as long as m–cu, 1–SR–M 1.2 times as long as 1–M, 2–CU1 somewhat longer than 1–CU1 (Fig. 51). – Sclerotized plate of first tergite spatulate, that of second tergite rather ridge-shape as in Fig. 52. Tergites 1–2 dull, rest of tergites subshiny. Ovipositor sheath shorter than hind basitarsus (Fig. 53). – Antenna yellow, distally darkening. Head and mesosoma yellow, mesoscutum and scutellum light brownish; tergites 1–2 pale yellow, rest of tergites brown(ish); legs straw yellow. Wings hyaline, pterostigma and veins yellow.

m. Similar to the female. Body 1.5 mm long. First flagellomere a bit shorter than second flagellomere, first flagellomere five times as long as broad preapically, penultimate flagellomere three times as long as broad. Head in dorsal view 1.9 times as broad as long. Hind femur less thick, three times as long as broad distally (Fig. 54). Fore wing: pterostigma 2.6 times as long as wide and issuing r somewhat proximally from its middle. Meta- soma beyond tergites 1–2 brown.

Host – Leucoptera coffeella Guérin (Lep. Lyonetiidae ).

Distribution – Dominica, Guadeloupe.

Taxonomic position – Mirax (Centistidea) insularis Muesebeck is nearest to M. (C.) brasiliensis Brues , their shared features are the presence of notaulix on dorsal side of mesoscutum ( Figs 16 , 47) and light colour of body: to distinguish them see key-couplet 5.
