利用来自尼日利亚和下萨伊地区的palpalis舌蝇（Robineau-Desvoidy, 1830）（双翅目：舌蝇科）的蝇群，将两个微卫星位点Gpg19.62和Gpg55.3添加到x染色体图谱中，从而使该染色体上的位点数量增加到7个。在定位和其他杂交实验中，发现F-1和回交雄性不育。本研究中发现的不育模式与某些采采亚种杂交过程中发现的不育模式的相似性表明，名义分类群g.p. palpalis可能包含隐分类群。两个种群雄性蜂后卵头宽度的差异与这一结论一致。
Using flies from colonies of Glossina palpalis palpalis (Robineau-Desvoidy, 1830) (Diptera: Glossinidae) that originated in Nigeria and Bas-Zaire, the two microsatellite loci Gpg19.62 and Gpg55.3 have been added to the X-chromosome map, thus increasing to seven the number of loci mapped on that chromosome. During the mapping and other crossing experiments, sterile F-1 and backcross males were found. Similarities between the patterns of sterility found in the present study and those occurring during hybridization of some subspecies of tsetse suggest that the nominal taxon G. p. palpalis may contain cryptic taxa. Differences in the width of the postgonite head of males from the two colonies were consistent with this suggestion.
