Giant Water Bug in white pot. In the present study, the chromosome complement and the behavior of meiotic chromosomes of L.

lthocerus For standard staining, the fixed testes stained with lacto-acetic orcein were squashed on slides. The presence of an m-chromosome pair was claimed to be a characteristic of the family Belostomatidae Ueshima Four testicular cell types found in each testis of Lethocerus indicus. The arrangement of bivalents did not form a particular pattern. Occurrence Occurrence Occurrence Records.


Large ponds with emergent vegetation such as Typha sp.

Length less than 20 mm; tylus not prominent; color pale brown or testaceous; head only slightly longer than front lobe of pronotum.

However, in meiotic cells at diplotene stage, the neo-XY bivalent was clearly seen to be composed of two chromosomes joined together, with one side bigger than the other. Curiously, Kraus reported indius in the absence of sufficient size males, eggs will also be indicue on backs of females. Enumerates geographic entities where the taxon lives.

Second, the chromosome number difference might be due to the occurrence of chromosome polymorphism. Instead, the occurrence of m-chromosome univalents was the result of desynapsis, not of asynapsis Nokkala and Nokkala In the case of autosomal univalents, they behave in the same way as sex chromosome univalents do.
