The two species Alpheus inca and Alpheopsis chilensis were frequently found to share the same burrows. In most burrows an heterosexual pair of each species was found. A strong positive correlation between the body length of female and male conspecifics cohabiting in a burrow was found both for Alpheus inca and for Alpheopsis chilensis. Similarly, a positive correlation existed between the mean body length of Alpheus inca and that of Alpheopsis chilensis occurring together in one burrow. Thus, a size-relationship between burrow cohabitants exists both in the intra-specific as well as in the inter-specific association of these shrimps. Most females, regardless of their reproductive stage, were accompanied by males. Within a particular burrow, females of the two species often were in the same reproductive stage, i.e. both were with embryos in a similar developmental stage, or both were without embryos. These data suggest that male and female conspecifics, as well as the pairs of the two species, remain together in the same burrow for relatively long time periods. It is proposed that the intra-specific communication system of snapping shrimp facilitates the development of inter-specific associations, such as the one reported herein.1 aBoltana, S.1 aThiel, M  u<Go to ISI>://00017140830000800429nas a2200133   4500008004100000245006300041210006300104300001400167490000700181100002000188700002500208700001600233856004600249       2004                        eng d00aFeeding habits of the burrowing shrimp Alpheus macellarius0 aFeeding habits of the burrowing shrimp Alpheus macellarius  a1199-12020 v841 aPalomar, N., E.1 aJuinio-Menez, M., A.1 aKarplus, I.  uhttps://alpheidae.myspecies.info/node/10201861nas a2200157   4500008004100000245016300041210006900204260000800273300001200281490000700293520132500300100001401625700001301639700001701652856003401669       2008                        eng d00aRevision of the Alpheus cristulifrons species complex (Crustacea : Decapoda : Alpheidae), with description of a new species from the tropical eastern Atlantic0 aRevision of the Alpheus cristulifrons species complex Crustacea   cMay  a543-5620 v883 aThe taxonomy of the snapping shrimp Alpheus cristulifrons Rathbun, 1900, previously reported from the eastern Pacific and western and eastern Atlantic, is reviewed based on molecular data (COI), morphology and colour patterns. Three species are recognized in the A. cristulifrons species complex. Alpheus cristulifrons sensu stricto is restricted to the western Atlantic, ranging from Florida and the Caribbean Sea to southern Brazil. The eastern Pacific A. cristulifrons sensu Kim & Abele, 1988 corresponds to A. utriensis Ramos & Von Prahl, 1989, ranging from the Gulf of California to Colombia; this species can be separated from A. cristulifrons by the absence of balaeniceps setae on the male minor chela and the presence of bands on the antennular and antennal flogella. The eastern Atlantic A. cristulifrons sensu Crosnier & Forest, 1966 is described as A. xanthocarpus sp. nov. based on recently collcctcd material from the island of Sao Tome in the Gulf Guinea; this species differs from A. cristulifrons by the posteriorly more extending rostral carina and the presence of conspicuous yellow spots on the carpus and chela of the second pereiopod. Molecular data suggest that A. utriensis is the eastern Pacific sister clade to the amphi-Atlntic clade that includes A. cristulifrons and A. xanthocarpus sp. nov.1 aAnker, A.1 aHurt, C.1 aKnowlton, N.  u<Go to ISI>://000257179800014
