590 PROTOZOOLOGY 



Suborder 2 Adeleidea Leger 



The Adeleidea are on the whole similar to Eimeridea in their 

 habitat and development, but the micro- and macro-gametocytes 

 become attached to each other in pairs during the course of develop- 

 ment into gametes (Fig. 253), and each microgametocyte produces 

 a few microgametes. The zygote becomes oocyst which produces 

 numerous sporoblasts, each of which develops into a spore with 2 or 

 4 sporozoites.

Family 1 Adeleidae Leger 



Genus Adelea Schneider. Zygote develops into a thinly walled 

 oocyst with numerous flattened spores, each with 2 sporozoites; in 

 arthropods. 



A. ovata S. (Fig. 253). In the gut of Lithobius forficatus; merozoites 

 17-22^ long; oocysts elongate oval, 40-50/z by 30-40m; 17-33 or 

 more spores; spores circular, flattened, 20m by 4/z (Hesse, 1910a). 

 Life cycle (Schellack and Reichenow, 1913, 1915). 



Genus Adelina Hesse. Oocyst thick-walled; spores spherical, com- 

 paratively small in number; in the gut or coelom of arthropods and 

 oligochaetes (Hesse, 1910, 1910a). 



A. dimidiata (Schneider) (Fig. 254, a). In the gut of Scolopendra 

 cingulata and other myriapods; oocysts with 3-17 spores (Schellack, 

 1913). 



A. octospora H. (Fig. 254, b). Spherical oocyst contains spores; in 

 the coelom of Slavina appendiculata (Hesse, 1910a). 



A. deronis Hauschka and Pennypacker. In peritoneum of Dero 

 limosa; oocyst contains 12 (10-14) spores; meiosis at the first zygotic 

 nuclear division; haploid chromosome number 10; the life cycle is 

 completed in 18 days at room temperature (Hauschka, 1943). 



Genus Klossia Schneider. Oocyst with numerous spherical spores, 

 each with 3-10 sporozoites. Several species. Life cycle (Xabih, 1938). 



K. helicina S. In the kidneys of various land-snails, belonging to 

 genera Helix, Succinea, and Vitrina; oocyst with a double envelope 

 120-180/z in diameter; spores 12/x in diameter, with 5-6 sporozoites 

 (Debaisieux, 1911). Cytology and development (Naville, 1927). 



Genus Orcheobius Schuberg and Kunze. Macrogametes vermi- 

 form; oocyst with 25-30 spores, each with 4 (or 6) sporozoites.
