Isospora albogularis sp.nov. (Apicomplexa: Eimeriidae) from the yellow-headed gecko, Gonatodes albogularis (Reptilia: Gekkonidae)

Steve J. Upton, Paul S. Freed

Come spesso accade nelle feci degli animali in libertà, sono presenti frammenti di prede, in particolare di piccoli insetti o crostacei.
Grazie a questi frammenti il Dr. Steve J. Upton e il Dr. Paul S. Freed in Costa Rica, hanno classificato una nuova specie di isopode (Isospora albgularis sp. nov.), rilevata negli escrementi di un piccolo geco Gonatodes albogularis (Sphaerodactylidae).

ABSTRACT

Canadian Journal of Zoology, 1990, 68(6): 1266-1267, 10.1139/z90-188

A new species of isosporan was recovered from the fecal contents of three of five yellow-headed geckos, Gonatodes albogularis, collected from Liberia, Guanacaste Province, Costa Rica. Sporulated oocysts of Isospora albogularis sp.nov. are subspherical, 29.5 × 26.9 (26.4–32.0 × 22.4–30.8) μm, with a shape index (length/width) of 1.1 (1.0–1.3). A micropyle, oocyst residuum, and polar granule are absent. Sporocysts are ovoid, 14.9 × 10.8 (13.6–16.0 × 10.2–11.4) μm, with a shape index of 1.4 (1.3–1.5). Both Stieda and substieda bodies are present, and the end opposite to the Stieda body is normally tapered slightly.
