Abstract

The mangrove cricket Apteronemobius asahinai is endemic to mangrove forest floors in China, Southeast Asia and the Ryukyu archipelago (Amamiohsima, Okinawa, Miyako, Ishigaki and Iriomote Islands) of Japan. We developed six polymorphic microsatellite markers for the mangrove cricket from genomic DNA libraries enriched for CA, GA, AAG and ATG motifs. The M13-tailed primer method was used in the process of screening of amplification and polymorphism of primers. A total of 64 specimens from two populations (one from Okinawa and the other from Iriomote) were genotyped for allelic diversity. The average number of alleles per locus was 4.67 and 6.67 for Okinawa and Iriomote populations, respectively. A significant genetic differentiation was detected between the two populations (pairwise FST 0.2404). These polymorphic microsatellite loci will be useful in ongoing studies of the population genetic structure of the mangrove cricket including several populations in the Ryukyu archipelago.
