Egg shell morphology of an amblyceran louse, Hohorstiella rampurensis (Phthiraptera) infesting ring dove, Streptopelia decaocta

Scanning electron microscopy (SEM) study showed that miniature rice grain like egg shell of Hohorstiella rampurensis was covered by obliquely placed opercular disc. The apophyses were present only on one side of the egg shell. There were 25-35 long elongated rod like apophyses (apically turned), which were arranged in 3-4 rows and occurred in pair. The nature of egg shell of H. rampurensis characteristically differed from that of H. lata (the only species of Hohorstiella studied, so far). The study further indicates about the role of egg morphology as a guide to louse taxonomy.
