3.4 Overlapping Sequences and Intergenic Spacers
There are 11, 8 and 5 gene overlapping regions in A.virgata ,H.nephele and O.maga mitogenomes, respectively, all ranging in size from 1 to 10 bp. The total lengths of the 3 mitogenomes ranges from 21 to 48 bp (Table 2). The longest of A.virgatamitogenomes is 10 bp located between nad4 and nad4L , the longest of H.nephele is 25 bp located betweentrnL1 -rrnL , while the longest of O.maga is 8 bp located between trnW-trnC . Four identical overlapping regions, namely the nad2-trnW (2 bp), trnW-trnC (8 bp),atp8-atp6 (7 bp) and atp6-cox3 (1 bp) are all present in these 3 mitogenomes (Table 2). Nineteen, thirteen and sixteen intergenic spacers, ranging from 1 to 77 bp, from 2 bp to 53 bp and 1 bp to 78 bp, with their longest (77bp, 53bp, 78bp), are located between trnQand trnW , are existed in O.maga , A.virgata andH.nephele mitogenomes, respectively (Table 2).
