Leucocytozoon ibisi n. sp.

(gures 5, 6)

Type host. Threskiornis molucca Cuvier (white ibis).

Type locality. Currumbin , Queensland, Australia .

Basis of description

Macrogametocyte. A parasite with small round morphs only, not exceeding about 13 m m in diameter ( table 1), exhibiting the usual staining characteristics of the genus. Nucleus slightly ovoid occupying a central to subcentral position with a small round karyosome visible; cytoplasm granular with a few hyaline vacuoles sometimes present. Host–parasite complex indicates a maximum diameter of about 15 m m; host cell nucleus occupies a peripheral position around a quarter to onethird of the parasite circumference (gure 5).

Microgametocyte. Similar to the macrogametocyte but more variable in shape and slightly smaller in overall dimensions ( table 1); exhibiting the usual diOEerentiating characteristics of the genus. The host cell nucleus covers slightly more of the parasite circumference (gure 6). No distinctive karyosome visible in dispersed parasite nucleus. Ratio of macrogametocyte s to microgametocyte s is 3:2.

Hapantotype. IRCAH:G46312 5 from Threskiornis molucca , coll. Lederer, 20 November 1998, Currumbin , Gold Coast, Queensland, Australia .
