Brunner's grasshopper

Paratylotropidia brunneri is a of -throated in the , first described by Scudder in 1897. The species has been the subject of cytogenetic study due to its unusual structure, with 19 chromosomes in male including four V-shaped multiples. It is found in North America, primarily in the north-central United States.

Chromosomal characteristics

P. brunneri exhibits an unusual karyotype with 19 in male and 20 in females. Four chromosomes are V-shaped multiples. When counting each arm of the multiples separately, the count matches the typical complement of 23 in males and 24 in females. The has an XO sex determination system in males, with one V-shaped multiple limited to males showing differential heteropycnosis during meiotic prophase.
