Figs. 17–19, 21–23 View FIGURES 17–25 , 26 View FIGURE 26 .
External diagnosis ( Corrêa 1947). Very similar to Dolichoplana striata in size (up to 20 cm in length) and color pattern (olive-brown background and longitudinal stripes). Specimens can have six stripes, being identical to Dolichoplana striata , or only five stripes, with a single median stripe more conspicuously marked than the paired median stripes of specimens with six stripes. Specimens with five dorsal stripes have a pale venter with three brownish or grayish stripes, a fine median stripe and a broader lateral stripe on each side.
The absence of a head plate differentiates it from both species of Bipalium . The paired eyes differ from the multi eyed species of Caenoplanini as well as Geoplana multipunctata . The large size and the number of stripes differ it from Rhynchodemus sylvaticus and Diporodemus yucatani .
Remarks. Dolichoplana carvalhoi was originally described based on specimens that are externally identical to Dolichoplana striata , but whose copulatory apparatus presented some small variation ( Corrêa 1947). Specimens with only five stripes were found later, and a karyotype analysis revealed that six-striped specimens are triploid (3n) while five-striped specimens are diploid (2n) ( Álvarez & Almeida 2007). Dolichoplana carvalhoi is likely a junior synonym of Dolichoplana striata and, although this has already been suggested ( Froehlich 1967), the synonymization was never formally presented.Since the six-stripe pattern is identical in both species of Dolichoplana , these specimens are often identified as Dolichoplana striata , while five-striped specimens are determined as Dolichoplana carvalhoi solely because this pattern was never formally recorded in Dolichoplana striata . Here we use the name Dolichoplana striata for the six-striped specimens and Dolichoplana carvalhoi for the five-striped specimens. However, we believe that these two names indeed represent a single species.
