67. Trechus [Bradycellus] Tibialis, Kirby.—Length of body 2 3/4 lines. Only a single specimen taken.[47] Body black, somewhat glossy. The tip of the palpi and scape of the antennæ are rufous; the prothorax is rather wider than long, but nearly square; the short basilar furrows observable in Argutor distinguish species from the succeeding ones: elytra lightly furrowed, furrows impunctured; in the usual situation adjacent to the second furrow a little beyond the middle of the elytrum a very minute puncti from impression is just discernible ; the lateral margin and suture at the apex of the elytra are reddish: the tibiæ are rufous but the cubit is black, at the tip , the tarsi are darker, the hand has four dilated joints as in the other species of the genus.

Abstract Propagurus haigae (McLaughlin, 1997), a relatively large-sized species of Paguridae, is reported for the first time from Japanese waters based on a single specimen collected from a depth of 620 m off Ie Island, central Ryukyu Islands, southwestern Japan. It is the third species of the genus Propagurus McLaughlin & de Saint Laurent, 1998 known from Japanese waters. The present specimen greatly extends the distribution range of P. haigae, because the previous northernmost record was the Molucca Sea in Indonesia.

A New Species

A new species of the genus Munida Leach, 1820, is described and illustrated based on a single specimen from the deep-sea hydrothermal vent on the Eastern Pacific Rise. Munida alba sp. nov. closely resembles M. ampliantennulata Komai, 2011, M. watatsumin Komai, 2014. and M. magniantennulata, but differences in the morphologies of the third maxilliped, pollex of the cheliped and the third segment of the antennal peduncle readily distinguish the new species from the three relatives. The new species is the fourth of the genus occurring at the hydrothermal vent areas.

The Quagga shark Halaelurus quagga (Alcock, 1899) is one of the poorest known scyliorhinid (Carcharhiniformes) sharks of the world, described from a single specimen collected from the Arabian Sea coast of India (off Malabar). Since its description, the only other published reports of this species are of specimens from Somalia. This paper reports on H. quagga from Indian waters, more than 100 years after its description, and only the third report of specimens of this species globally. A re-description of H. quagga is also provided based on the recent Indian specimens.

Computer Based

ABSTRACTA detailed account of the morphology and ontogeny of the late Middle Cambrian crustacean †Henningsmoenicaris scutula is presented. Ten successive ontogenetic stages could be recognised in the material collected from various localities in Sweden. Morphogenetic changes include the development of a pair of stalked lateral eyes and the increase in the number and size of appendages and their setal armature. Notably, early stages lack ‘proximal endites’ on all post-antennular appendages; such a spine-bearing endite has previously been thought to appear simultaneously on these limbs. In †H. scutula a single functional endite appears on the third limb in an advanced stage; an additional endite appears on the second limb and, subsequently, further endites appear on more posterior limbs. Furthermore, a single specimen of †Sandtorpia vestrogothiensis gen. et sp. nov. is described. Based on this new information and data of other ‘Orsten’ taxa, particularly those assigned already to the early evolutionary lineage of Crustacea, a small-scale computer-based phylogenetic analysis was performed. This resolved the basal branchings of Crustacea s. l. as follows: †Oelandocarididae (=†Oelandocaris oelandica+†H. scutula+†S. vestrogothiensis)+(†Cambropachycopidae (=†Goticaris longispinosa+†Cambropachycope clarksoni)+ (†Martinssonia elongata+Labrophora (=†Phosphatocopina+Eucrustacea))). Plotting ontogenetic data on the phylogram and comparing the ground pattern at every node led to the detection of three peramorphic heterochronic events in the evolutionary lineage towards Eucrustacea.

A new family (Lacantuniidae), genus and species of catfish, Lacantunia enigmatica, is described from the Río Usumacinta basin of Chiapas, México. This odd siluriform is diagnosed by five distinctively autapomorphic and anatomically complex structures. The fifth (last) infraorbital bone is relatively large, anteriorly convex and remote from a prominent sphenotic process. The lateral margin of the frontal, lateral ethmoid and sphenotic bones are thick at the origins of much enlarged adductor mandibulae and levator arcus palatini muscles; otherwise the skull roof is constricted and flat. One pair of cone-shaped "pseudo-pharyngobranchial" bones is present at the anterior tips of enlarged cartilages medial to the first epibranchial. A hypertrophied, axe-shaped uncinate process emerges dorsally from the third epibranchial. The gas bladder has paired spherical, unencapsulated diverticulae protruding from its anterodorsal wall. Lacantunia enigmatica cannot be placed within or as a basal sister lineage to any known catfish family or multifamily clade except Siluroidei. This species may represent an ancient group, perhaps of early Tertiary age or older, and it adds another biogeographic puzzle to the historically complex Mesoamerican biota.

This parasite approaches Neumann's Haematopinus (Polyplax) maniculatus, but is immediately recognised by the truncate proboscis, by the “ olecranon process ” of the hind pair of legs, and by the remarkable “ comb ” which terminates the abdomen of the ♀. Perhaps a new genus should be made to receive it.Linear, abdomen about four times the length of the head and thorax together. Head very broad, proboscis truncate, its lateral margins diverging to as far as the antennae, behind which the head enlarges at right angles. Post-antennal area rectangular, broad ; the occipital margin a little convex. At each posterior angle a long hair ; on the under surface, at about the level of the antennae, two short bristles, one on each side. Antennae of five segments, the first being thick and stout, the second narrower and the longest, the third short, and the fourth broad with a sharp prominence at the post-axial distal corner. Adjoining the prominence a small circular sense-organ which crosses the joint and occupies part of the base of the terminal segment. The latter is longer than the third or fourth, and has several spines at the end. Thorax broader than the head and broader behind than in front. A large flattened spheroidal spiracle at each lateral margin.

This spccies is extlemely similar to C. maxillosus, and its American representative. The following circumstances principally distinguish them. The anterior angles of the prothorax in C. maxillosus are thinly cloathed with shortish black hairs; in C. villosus, these hairs are cinereous, longer, mole numerous, and cover a larger portion of the angle; in the former, the band of the elytra is whiter and wider than in the latter; in the former also the back of the abdomen, especially the third and fourth segments, is mottled with cinereous hairs; in the latter the second and third have each a cinereous band interupted in the middle; again the four first ventral segments in C. maxillosus are thickly covered with decumbent cinereous hairs, with each a lateral black spot on both sides, while in C. villosus

AbstractThe phylogenetic relationships of the diving beetle (Dytiscidae) genus Leuronectes Sharp are revised based on a cladistic analysis of seven Agabinae genera and 54 morphological and chaetotaxic characters from larvae. For this purpose, larvae of L. curtulus Régimbart are described and illustrated in detail for the first time, with particular emphasis on morphometry and chaetotaxy. The results show that Leuronectes is well placed within Agabinae based on the absence of natatory setae on tibia and tarsus in instars II and III, the urogomphus composed of two urogomphomeres, and the absence of secondary setae on urogomphus. Leuronectes is resolved as part of a basal polytomy along with Platynectes Régimbart and a clade formed by the remaining agabine genera. Leuronectes shares with Platynectes the setae UR2, UR3 and UR4 not inserted contiguously, with Platambus Thomson the anterolateral lobes of frontoclypeus not projected beyond anterior margin, with Hydrotrupes Sharp the seta AB9 inserted dorsolaterally, and with Ilybius Erichson the seta LA10 inserted submedially. Leuronectes is unique within Agabinae in having the apical lateroventral process of the third antennomere not protruding and additional ventroapical pores on third antennomere, and is unique within the dytiscid genera studied in having the seta LA12 inserted submedially and one additional spine-like seta inserted on the lateral margin of abdominal segment VIII.
