<I>Bathysquilla Microps</I> BULLETIN OF MARINE SCIENCE, 61(3): 929–933, 1997 BATHYSQUILLA MICROPS (MANNING, 1961), A DEEP-SEA MANTIS SHRIMP NEW TO THE BRAZILIAN FAUNA (CRUSTACEA: STOMATOPODA: BATHYSQUILLIDAE) Marcos Tavares and Joel Braga de Mendonça, Jr. Thirty-five species of mantis shrimps are known from Brazil, Uruguay and Argentina (Lemos de Castro, 1955; Manning, 1969; Gomes Correia, unpubl.; Boschi, Fischbach and Iorio, 1992), however, no bathysquillids have been recorded from that area. Deep-sea surveys conducted off the coast of Brazil in 1987 by the “Marion Dufresne” as part of an agreement between Universidade Santa Úrsula, Rio de Janeiro, and the Muséum national d’Histoire naturelle, Paris, for the study of the deep-sea fauna (Guille and Ramos, 1988; Manning, Tavares and Albuquerque, 1989; Tavares and Albuquerque, 1990a; 1990b; Tavares, 1991a; 1991b), revealed the presence of Bathysquilla microps (Manning, 1961) in southeastern Brazil. The only specimen obtained was a male dredged at depths be- tween 750 and 785 m, which is deposited in the collections of the Museu Nacional do Rio de Janeiro (MNRJ). Terminology and propodal index used below are those discussed in Manning (1969). Abbreviations used include: st, station; CP, beam trawl; tl, total length; mm, millimeters.

Previous accounts.— Manning (1961; 1968; 1969): descriptions; drawings of anterior portion of body, rostral plate, male accessory organ, and outline of telson; photographs of body in dorsal and ventral views, and of raptorial claw. Manning and Struhsaker (1976): outline of front, carpus of claw and basal prolongation of uropod. Takeda (1983): color photograph of the entire body in dorsal view. Bruce (1988): additions to previously pub- lished descriptions; outline of front and of sixth thoracic sternite. Moosa (1985): draw- ings of anterior part of body; exposed thoracic sternites and first two abdominal somites in lateral view, raptorial claw, fourth to sixth abdominal somites, telson and uropod.

Variations.— In B. microps the mandibular palp is typically three-segmented (Man- ning, 1961), but in our specimen palp from left mandible has only two segments (Fig. 1 E). Because the proximal and distal segments of the two-segmented palp have the charac- 929 930 BULLETIN OF MARINE SCIENCE, 61(3): 929–933, 1997 Fig. 1a-c, e,f. Bathysquilla microps (Manning, 1961).

Scales: A-B, 10 mm; E-F, 3 mm. teristic shape and setal types of the distal and proximal segments of a typical three-seg- mented palp (Fig. 1F), it seems that the penultimate segment did not differentiate. According to Manning (1969) and Moosa (1985) shape of eyes and abdomen ornamen- tation in B. microps are correlated with age, small specimens (tl 53 mm) have more globular eyes than the larger ones (tl 141 mm); also the abdominal spination is more pronounced in adults. The number of teeth on the raptorial claw varies from 13 to 15 in B. microps. The Western Atlantic specimens examined by Manning (1961: 694, Fig. 3; 1969: 96, Fig. 26c; Manning and Struhsaker, 1976: 445) had 13-15 teeth on the claw. Moosa (1985: 373) reported a large male (tl 141 mm) with 13 teeth on the raptorial claw, and a small male (tl NOTES 931 53 mm) with 14 teeth, both from Philippines. The claw with 12 teeth illustrated in Moosa (1985: 372, Fig. 1c) may not be accurate. The right claw of the Brazilian specimen has 14 teeth, while left claw has 15 teeth, including a very small proximal spine (Fig. 1 B). Variation in the number of teeth claw has also been reported in B. crassispinosa, 9 - 11 (Fukuda, 1910: 146; Manning, 1969: 98; 1991: 3; Moosa, 1985: 371; Bruce, 1988: 88). Manning (1991) observed that not only the late larva but also the adults of B. crassispinosa can have nine teeth. Propodal index for our material (pi 075; tl 152 mm) is within the variation found by Manning and Struhsaker (1976) for males from Western Atlantic (pi 074 to 092; tl 68-255 mm). The western South Atlantic and the Caribbean material agree in almost all regards, however in the Brazilian specimen the last movable spine on the outer margin of penultimate uropod segment does not extend beyond the midlength of the distal segment (Fig. 1A), whereas in the Caribbean specimens it does extend beyond the midlength of the distal segment (Maning, 1969). Remarks.— The family Bathysquillidae contains two genera and four species as fol- lows: Bathysquilla wetherelli (Woodward, 1879) from the Eocene of England (Quayle, 1987: 609), and the Recent species Bathysquilla crassispinosa (Fukuda, 1909), B. microps, and Altosquilla soelae Bruce, 1985. The Indo-West Pacific species Indosquilla manihinei Ingle and Merret, 1971, previously included in the Bathysquillidae, has been recently moved into a new family, Indosquillidae (Manning, 1995). B. crassispinosa and B. microps are closely related species, differing in: (a) the number of teeth on the raptorial claw, 13-15 in B. microps and 9-11 in B. crassispinosa; (b) the shape of the eyes, slender in B. microps and globular in B. crassispinosa; and (c) the number of dorsal spines on the carpus of the raptorial claw, one dorsal spine in B. microps and two in B. crassispinosa (Manning, 1969). Perhaps the most striking difference be- tween B. microps and B. crassispinosa is the presence, only in B. crassispinosa, of a strong and sharp ventral spine (Fig. 1C,D) on the basal segment of the uropod (Gordon, 1929; Manning, 1969), and an acute ventral spine on the proximal segment of the exopod (Fig. 1C,D). Geographic and bathymetric range.— B. microps is known from both Western Atlantic (Bahamas, Florida, Gulf of Mexico, Suriname, French Guiana, and southeastern Brazil, this report), and Indo-West Pacific (Hawaii Islands, Mariana Islands, Australia and Phil- ippines), while its Indo-West Pacific counterpart, B. crassispinosa, occurs only in scat- tered localities in Japan, South China Sea, Philippines, Australia, Madagascar, Mozambique, and South Africa (Manning, Kropp and Dominguez, 1990; Bruce, 1988). B. microps is found between 604 and 1519 m, whereas B. crassispinosa has been re- corded in depths between 200 and 400 m. It seems that there is no correlation between body size and depth range in these two species, as large and small specimens can occur in similar depths (Manning, Kopp and Dominguez, 1990; Moosa, 1985: 371, material).

MZCROPS AND B. CRASSZSPZNOSA BY RAYMONDB. MANNINGAND PAUL STRUHSAKER Smithonian Institution, Washington, D.C. 20560, and National Marine Fisheries Service, Honolulu, Hawaii 96812 During the sampling program of the National Marine Fish- eries Service (NMFS) aboard the NOAA research vessel TOWNSENDCROMWELL in 1972, one specimen of an unusual stomatopod was taken by trawl off Maui, Hawaiian Islands, at a depth of 731-786 m. It proved to be an adult female of the rare BathysquiUa microps (Manning, 1961), then known from only three specimens taken in 732-952 m off southeastern Florida and the Bahamas (Manning, 1969a). Bathysquilla microps was the second species of bathy- squillid to be recognized, the first being B. crmsispinosa (Fukuda, 1909), originally described from Japan and subse- quently recorded from additional localities in the western Indian Ocean. It occurs in depths between 230 and 310 m. A third bathysquillid representing another genus, Zndosquilla manihinei Ingle and Menett, 1971, was described from a unique specimen taken off Cosmoledo Atoll, Indian Ocean, in a depth of 420 m. Apparently bathysquillids are restricted to moderate depths of the outer shelf and upper slope (Fig. 2). The bathysquillids live in far greater depths than the major- ity of known stomatopods. The deepest record given by Kemp (1913) in his monograph of the Indo-West-Pacific stomato- pods was 370-419 fm (677-767 m) for Squilloides kptosquilb from the “Investigator” collections.

(1997) Numbers of Hawaiian Species: Supplement 2, Including a Review of Freshwater Invertebrates i LUCIUS G. ELDREDGE^ & SCOTT E. MILLER (Hawaii Biological Survey, Bishop Museum, 1525 Bernice Street, Honolulu, Hawaii 96817, USA) This is Supplement 2 to our earlier tabulation of species known from Hawaii (El- dredge & Miller, 1995; Miller & Eldredge, 1996; also see Mlot, 1995). The Hawaii Bio- logical Survey continues to work on the compilation of checklists and bibliographies; some short lists of invertebrates are included in this supplement, especially for those species inhabiting freshwater. This supplement should be viewed as a further interim report subject to future change. See Eldredge & Miller (1995) for definitions and scope and see Allison et al. (1995) for review of marine species. From literature and unpublished sources, 22,077 species have been recorded from the Hawaiian Islands and surrounding waters. Of these, 8,805 are endemic to the Ha- waiian Islands, and 4,373 are nonindigenous species. This is an ongoing count of the biota, e.g., the completed checklist of the foraminiferans totaled 755 species, rather than the 1000+ in the original estimate. Particular interest has been paid to the freshwater ani- mals in this supplement [see Table 2 for taxa and citations]. Hawaii Biological Survey is in the process of posting species checklists in search- able interfaces for the Hawaiian organisms on the Internet at: http://www.bishop.hawaii.org/bishop/HBS/ More than 15,000 species are currently available (including terrestrial arthropods, native and alien land and freshwater snails, Foraminifera, flowering plants, amphibians, reptiles, birds, and mammals; with more taxa to be added).

  • RECORDS of the HAWAII BIOLOGICAL SURVEY for 1996 Part 1: Articles
    RECORDS OF THE HAWAII BIOLOGICAL SURVEY FOR 1996 Part 1: Articles Editor’s Preface We are pleased to present the third annual compilation of Records of the Hawaii Biological Survey. The number and diversity of taxa reported in these issues attest to the value of the Records as part of the ongoing effort to inventory the Hawaiian biota. The Hawaii Biological Survey, established by the Hawaii State Legislature in 1992 as a program of the Bishop Museum, is an ongoing natural history inventory of the Hawaiian Archipelago. It was created to locate, identify, and evaluate all native and non- native species of flora and fauna within the State and maintain the reference collections of that flora and fauna for a wide range of uses. In coordination with related activities in other federal, state, and private agencies, the Hawaii Biological Survey gathers, analyzes, and disseminates biological information necessary for the wise stewardship of Hawaii’s biological resources The discovery of a new noctuid moth from the mountains immediately behind the urban environment of Honolulu demonstrates that much remains to be learned about the native biota. At the same time, the continuing parade of new records of naturalized non- native plants and alien arthropods is alarming. Some of the highlights of Records of the Hawaii Biological Survey for 1996 include: • an update of numbers of species in Hawaii, including a review of freshwater inver- tebrates; • an overview of the history of spread and current status of the invasive pest weed, Miconia calvescens; • new records of plants, insects, and other invertebrates resulting from field surveys and continued curation of Hawaiian collections at Bishop Museum and else- where; • a summary and bibliography of a checklist of Hawaiian Foraminifera (755 species), the checklist of which will be published elsewhere; • a catalog of the nonindigenous land and freshwater snails and slugs of Hawaii, to supplement the recently published catalog of native species.

A hyoNg Australian Museum, 6 College St., Sydney, NSW 2010, Australia, and School of Biological, Earth & Environmental Sciences, University of New South Wales, Kensington, NSW 2052; email: [email protected] Abstract . The endemic hawaiian mantis shrimp, Parvisquilla sinuosa (Edmondson, 1921), is redescribed based on the holotype and additional specimens. The new material includes the first known male of the species, whose morphology confirms the presence of sexual dimorphism in uropo - dal protopod length, as observed in other species of Parvisquilla . of the three known species of Parvisquilla , P. sinuosa is unique in having a dorsally carinate rather than dorsally tuberculate telson characteristic of its congeners, P. multituberculata (Borradaile, 1898) and P. dominguez Ahyong & Erdmann, 2003. Introduction Twenty species of mantis shrimp (Stomatopoda) are currently known from the hawaiian Islands (Eldredge & Miller 1997, Ahyong 2002), of which one species, Parvisquilla sinuosa (Edmondson, 1921), is apparently endemic. Parvisquilla sinuosa , however, is poorly documented, having neither been adequately described nor figured. The species is redescribed and figured here based on the holotype and other material. The present study is dedicated to the memory of Lu Eldredge for his major contributions to hawaiian zoology and for making the holotype of P. sinuosa available for study before his unfortunate passing. Methods Morphological terminology largely follows Ahyong (2001, 2012a).

  • The Evolutionary History of Stomatopoda (Crustacea: Malacostraca) Inferred from Molecular Data
    The evolutionary history of Stomatopoda (Crustacea: Malacostraca) inferred from molecular data Cara Van Der Wal1,2, Shane T. Ahyong2,3, Simon Y.W. Ho1 and Nathan Lo1 1 School of Life and Environmental Sciences, University of Sydney, Sydney, Australia 2 Australian Museum, Sydney, Australia 3 School of Biological, Earth and Environmental Sciences, University of New South Wales, Kensington, Australia ABSTRACT The crustacean order Stomatopoda comprises seven superfamilies of mantis shrimps, found in coastal waters of the tropics and subtropics. These marine carnivores bear notable raptorial appendages for smashing or spearing prey. We investigated the evolutionary relationships among stomatopods using phylogenetic analyses of three mitochondrial and two nuclear markers. Our analyses recovered the superfamily Gonodactyloidea as polyphyletic, with Hemisquilla as the sister group to all other extant stomatopods. A relaxed molecular clock, calibrated by seven fossil-based age constraints, was used to date the origin and major diversification events of stomatopods. Our estimates suggest that crown-group stomatopods (Unipeltata) diverged from their closest crustacean relatives about 340 Ma (95% CRI [401–313 Ma]). We found that the specialized smashing appendage arose after the spearing appendage ∼126 Ma (95% CRI [174–87 Ma]). Ancestral state reconstructions revealed that the most recent common ancestor of extant stomatopods had eyes with six midband rows of hexagonal ommatidia. Hexagonal ommatidia are interpreted as plesiomorphic in stomatopods, and this is consistent with the malacostracan ground-plan. Our study provides insight into the evolutionary timescale and systematics of Stomatopoda, although further work is required to resolve with confidence the phylogenetic relationships among its Submitted 25 July 2017 superfamilies.
