Alignment of highly conserved splice leader sequences (bases 1–40 of mini-exon gene) of H. muscarum and other species from the Leishmaniiae clade.

The variable AT-rich region (positions 11–19, bold) is shown by genus. Herpetomonas sp. appear to have an additional A or T residue, dependant on species at position 11.

可变AT富集区（AT-rich region）按属分类展示，其对应序列位置为第11至19位，已以加粗格式标注。短膜虫属（Herpetomonas）的物种似乎在第11位携带额外的腺嘌呤（A）或胸腺嘧啶（T）残基，该残基的类型因物种不同而存在差异。
