Checklist of Stomatopoda ( Malacostraca : Hoplocarida ) deposited in the MOUFPE collection , with a new record from Brazil

A total of 39 species of Stomatopoda were previously reported from marine and estuarine habitats of Brazilian waters. The present checklist is based on material deposited in the crustacean collection of Museu de Oceanografia Petrônio Alves Coelho, Universidade Federal de Pernambuco, city of Recife, Brazil (MOUFPE). The collection, deriving primarily from the northern and northeastern coast of Brazil, includes 667 samples and 1.301 specimens, distributed in four superfamilies, seven families, 14 genera and 33 species, including one holotype and two paratype. Apparent distribution gaps for five-species were filled. Two Brazilian endemic species had their southern geographical ranges increased (Neogonodactylus moraisi (Fausto Filho & Lemos de Castro, 1973) and Nannosquilla dacostai Manning, 1970) and one was recorded for the first time from northeast Brazilian waters [Alima neptuni (Linnaeus, 1768)]. There are now 42 species of Stomatopoda recorded from the Brazilian coast.


Introduction
The crustaceans of the order Stomatopoda, commonly known as mantis shrimps, are among the most aggressive crustacean predators and those with the most complex behavior (Ahyong and Harling, 2000).They are cryptic, benthic animals that are most abundant in marine depths less than about 200 m, although some occur in shallow brackish habitats, and others to 1500 m depth in soft or hard substrates (Ahyong et al., 2008).Ahyong et al. (2011) considered for the Manning, 1967; Gonodactyloidea, including the families Hemisquillidae Manning, 1980, Gonodactylidae Giesbrecht, 1910, Odontodactylidae Manning, 1980and Pseudosquillidae Manning, 1977;Lysiosquilloidea, including Lysiosquillidae Giesbrecht, 1910 andNannosquillidae Manning, 1980; Squilloidea with Squillidae Latreille, 1802; Eurysquilloidea comprising Eurysquillidae Manning, 1977 and Parasquilloidea with Parasquillidae Manning, 1995(Gomes Corrêa, 1998;Schram, 2010).In the last decades few studies were published in Brazil, dealing with distribution, diversity and systematic issues (Barreto et al., 2003;Coelho and Santos, 2003;Silva et al., 2003;Rodrigues and Young, 2005;Almeida et al., 2007a;2007b;2008;Bento et al., 2008;Albuquerque and Coelho, 2009;Bento and Melo, 2010;Lucatelli et al., 2012).Nevertheless, these are check-lists for restricted areas or papers dealing with new species.Thus, additional study would be useful in order to achieve a more thorough knowledge of the group in Brazil.The scientific collections are important sources to improve these issues and answer some taxonomic, phylogenetic and biogeographic questions.
There are three most important carcinological collections in Brazil that represent the Brazilian stomatopod fauna: Museu de Zoologia of Universidade de São Paulo (MZUSP), Museu Nacional of Rio de Janeiro (MNRJ) and Museu de Oceanografia Petrônio Alves Coelho of Universidade Federal de Pernambuco (MOUFPE).This paper reviews the identification of species deposited in the Museu de Oceanografia Petrônio Alves Coelho, Universidade Federal de Pernambuco, city of Recife, Brazil (MOUFPE, previously DOUFPE) and provides new records of Stomatopoda from Brazilian waters.
Material deposited in the crustacean collection of the MOUFPE was mainly identified by Petronio A. Coelho, and reviewed by Débora Lucatelli.This collection was started in the late 1950s and presently is the third largest carcinological collection in Brazil, with more than 14,000 samples (Coelho et al., 2008).The collection contains Stomatopoda mostly obtained during surveys along the continental shelf and littoral areas.Several oceanographic expeditions, however, also collected samples on the upper continental slope.The MOUFPE collection includes almost all Brazilian species and all species known from north and northeast regions.
The following information is included for each species: the type material (when available), the list of material examined (number of specimens, station, date, geographical coordinates, depth, voucher/ catalogue number), distribution, habitat and remarks (when necessary).The synonymies are limited to original papers (containing species description) and the first author list of references.
Classification of the species in families and higher taxa was based on Ahyong et al. (2011).The families within each superfamily and the species within each family follow Ahyong et al. (2011).Morphological terminology used for species descriptions follows Ahyong (2001).
Habitat: It was found among calcareous algae, rocks and in coral reefs, at depths from shallow subtidal to 70 m.These records are in agreement with Manning (1969), who reported this species to 73 m depth.
Remarks: The specimens agree with holotype description.The number of antennal articles was analysed, but it is highly variable and can not be used as a diagnostic character, the same was observed by Manning (1969).The number of movable spines varied from 11 to 12 on the specimens analysed, a similar range was found in other species of Neogonodactylus.
Habitat: It was found in coral reef locations, calcareous algae and seagrass beds from shallow subtidal to 85 m (Manning, 1969).Our records are in agreement with Manning (1969), and the lower depth limit is slightly increased from 80 to 85 m.
Remarks: The uropodal endopod outline of type series and additional material studied herein are almost straight instead of sinuous as Manning (1969) reported.Furthermore, most of specimens analysed in this study do not bear a movable apex on submedian tooth of telson, but in some the apex was present, including the female paratype (TL 16 -28 mm), changing the diagnosis given by Manning (1969).
Remarks: The specimens analysed herein showed some morphological variations, as on rostral plate (extending or not until the base of ocular peduncle), carina swollen and telson's proportion.Manning (1969) described males with more swollen carinae than females, but the males analysed in the present contribution present swollen or slender carinae.The apical spinule was found in some males, although this was not mentioned by Manning (1969) or Ahyong and Norrington (1997).
Habitat: Hard substrates such as coral reefs and rock wall, among seagrass and sponges at depths from 0 to 85 m.The lower depth limit provided by Schotte and Manning (1993), 73 m, is herein extended to 85 m.

Neogonodactylus
Remarks: These specimens are either juveniles or damaged and identification to species level was not possible.
Remarks: The specimens agree very well with the description given by Manning (1969).The color was almost faded, but the dark band pattern cited by Schotte and Maninng (1993) was preserved.
Habitat: In coral reefs, rocky walls and burrows on sandy substrates, at depths from shallow subtidal to 28 m (Schotte and Manning, 1993).The deepest bathymetric limit is increased to 37 m.

Remarks:
The specimens analysed are in agreement with Manning's (1969) description.The mandibular palp was absent and the fused ocular scale showing a square shape.
Habitat: Back reef area on sandy patches and tidal flats exposed at low tide, from intertidal to 70 m (Schotte and Manning, 1993).
Remarks: Alima neptuni was described based on a larva of A. hyalina (Leach, 1817), which lead to a huge confusion when the adult forms were analysed (see Ahyong, 2001;Schotte and Manning, 1993).Manning (1962) studying larval development, synonymized A. alba with A. hyalina and Ahyong (2001) placed A. hyalina as junior synonym of A. neptuni, based on presence of two rounded lobes between terminal spines on uropodal protopod.Because the larval holotype of A. neptuni was lost and the description given by Linnaeus (1768) insufficient, Holthuis (2000) selected the lectotype of Squilla alba Bigelow, 1894 as the neotype of A. neptuni, making the two species objective synonyms, to fix the identity of the species.Alima neptuni is part of the genus group (with A. pacifica Ahyong, 2001) that share the following characters: six teeth on the dactylus of the raptorial claw, sharp telson denticles in adults and the uropodal protopod bears two lobes between the terminal spines (for more details, see Ahyong, 2001;2012).The specimens examined herein agree well with description by Ahyong (2001).

Conclusions
This paper records new distribution ranges for nine species.Squilla grenadensis was registered further north than the previously known occurrence in Rio Grande do Norte.
southernmost distribution limit was also increased for Neogonodactylus moraisi (to Rio Grande do Norte), Nannosquilla dacostai (to Rio Grande do Norte and Pernambuco).In other cases, the distribution gaps were filled to the north: Alachosquilla floridensis (to Rio Grande do Norte and Pernambuco), Bigelowina biminiensis (to Rio Grande do Norte), Eurysquilla plumata (to Pernambuco), and Meiosquilla tricarinata (to Rio Grande do Norte).Alima neptuni (Rio Grande do Norte and Paraíba) was recorded for the first time from Brazilian waters.
Furthermore, the collection contains some rare species, such as Nannosquilla dacostai Manning, 1970, Neogonodactylus moraisi (Fausto Filho andLemos de Castro, 1973) and Neogonodactylus minutus (Manning, 1969), which are endemic to Brazilian coast.Accordingly, there are now 42 species recorded for Brazil of which 33 are deposited in the MOUFPE collection.New records and new species should be found as additional samplings are made unraveling the biodiversity of these important but cryptic benthic animals.
. separate with a bilobed shape, as in the lectotype.The mandibular palp is present as cited byManning (1969).
Manning (1970)g (1969)selected the most intact male from syntypes as lectotype.The specimens agree with the lectotype identified byBigelow (1893).Manning (1969)incorrectly reported fused ocular scales in B. biminiensis; the ocular scales in the present series are Habitat: From 23 to 44 m depth.Remarks:Manning (1970)described the median prominence flanked laterally by obtusely rounded lateral projection, but the specimens analysed in this study do not present this feature.Otherwise the characters agree well with the original description.
