Intertidal burrowing shrimps (Axiidea: Callianassidae, Callichiridae; Gebiidea: Axiannassidae, Upogebiidae) collected along the Brazilian coast

The Axiidea in the Museum of Oceanography Petrônio Alves Coelho, Recife, Brazil, with Some Remarks on the Biology of the Species

“…After its description, this species was never recorded again in the southeastern region of Brazil, being only later reported by Coelho [13] in the northeastern region of the country. Recently Pachelle et al [49] and Hernáez et al [12] reported N. guara from Ceará and Maranhão, respectively. Specimens of N. guara deposited in the MOUFPE collection are in very poor condition.…”

“…Remarks. Lepidophthalmus siriboia is endemic to Brazil (from Pará to Bahia), occurring primarily in estuarine areas of the northeastern region [12,44]. This species is characterized by solitary habits [45].…”

“…This species can be easily distinguished from the other three congeners listed here, viz. N. guara Rodrigues, 1971 [50], N. guassutinga Rodrigues, 1971 [50], N. maryae Karasawa, 2004 [51], by a combination of characters, including frontal margin of the carapace having obtuse rounded anterolateral projections (vs. sharp anterolateral projections in N. maryae and N. guassutinga), and uropodal endopod widening distally (vs. narrowing distally in N. guara) (see [12]).…”

“…The axiidean fauna of Brazil has been summarized (as Thalassinidea) by Coelho [13], de Melo [14] and, recently (as Axiidea), by Hernáez et al [12]. The latter work listed 35 species across seven families [12]. This study provides a comprehensive review of the Axiidea deposited in the zoological collection of the 'Museu de Oceanografia Prof. Petrônio Alves Coelho (MOUFPE)' of the northeastern region of Brazil.…”

“…Axiidean shrimps constitute an important component of the Brazilian benthic communities [11,12]. The axiidean fauna of Brazil has been summarized (as Thalassinidea) by Coelho [13], de Melo [14] and, recently (as Axiidea), by Hernáez et al [12]. The latter work listed 35 species across seven families [12].…”
