Phylogeny reconstructions based on mtDNA and nDNA have become the standard in studies on relationships between taxa. Difficulties in obtaining material, for example because of small endemic distributions, often lead to gaps in datasets. Collections in natural history museums can provide us with material to fill these gaps, but extracting DNA from historical specimens can be challenging. We used a PCR protocol for small amounts of sample material and high PCR yield on eggs of specimens of the coral-dwelling gall crab family Cryptochiridae collected in 1984, including material from the eastern Atlantic species Detocarcinus balssi. We obtained DNA sequences from seven older museum specimens using newly developed primers, which we combined with COI sequences from recently collected material. Results show that D.balssi is closest to the Indo-Pacific species Utinomiella dimorpha and not closely related to one of the other three Atlantic Cryptochiridae species. The remaining newly acquired DNA sequences from museum material cluster with the respective sequences from recently collected specimens.
