This paper describes two new species of goby that were discovered by REEF surveyors during a special training project in the Veracruz Marine Park in Mexico in 2003. Individuals of the two mystery gobies were photographed by REEF's Lad Akins. In cooperation with the marine park, specimens were collected and subsequently described as new species by Dr. Mike Taylor. The new finds include a neon-type goby that hovers in shoals above coral heads (Jarocho Goby, Elacatinus jarocho) and a tiger-striped goby that rests on rocks and coral (Cinta Goby, Elacatinus redimiculus). Both species are currently only known from reefs in southwestern Gulf of Mexico.
