 fThelohania obscura. Kudo, 1929, p. 4, figs. 51-61. 



Developmental stages not studied. Sporont octosporoblastic 

 (fig. 178, il). Spores, when viewed in water after decolorization, 

 are broadly oblong, often with dissimilar extremities, with 

 a thin membrane containing within a rounded mass of homo- 

 geneous and refractile protoplasm showing a small knob 

 at one end and a clear oblong space at the other. The stained

Fig. 178. — Thelohania obscura Kudo. A, sporont containing eight 

 sporoblasts ; B, young spore ; C, mature spore. B and C 

 stained with Giemsa's stain. (After Kudo.) 



spores show a nucleus near one end and a coiled polar filament 

 forming an oblong mass {B, C). 



Dimensions. — Spores measure 4-5-5)u. by 3-3-5 /i. 



Remarks. — The record of T. legeri from India and the 

 descriptions of T. indica and T. obscura are based on material 

 sent to Kudo by M. 0. T. Iyengar from Bengal. As remarked 

 by the latter, these parasites form whitish translucent masses 

 beneath the cuticle of the thorax and the anterior abdominal 

 segments of the larvae. The infected segments show hyper- 

 trophy. None of the larvae showing these symptoms meta- 

 morphosed, and all died before pupation. Those that are 

 hghtly infected would be able to metamorphose into adults. 



Habitat. — Larva of Anopheles varuna Iyengar : BbngaIj.

Eight spores were seen to be closely packed within an oval 

 envelope. Spores were oval, refractive, apparently hard, with 

 a circular vacuole at one focus of the elhpse.
