A55BB523FFB5FF85FF7B269E08FAD99C.taxon	description	Description of male. Broadly similar to the female (vide Stock, 1997). Integument finely pitted. Trunk (Fig. 1 A), cephalon and lateral processes without any tubercles, but single long, slender setae arising mid-dorsally on posterior margin of cephalon and trunk segments two and three; cephalon widest at mid-length at point of attachment of ovigers, widened anteriorly at point of attachment of chelifores and palps; ocular tubercle absent. Abdomen articulated, slender, reaching distal margin of coxa 1 of fourth leg. Proboscis with conspicuous central constriction. Chelifore scape of one article, relatively flaccid, chela small, functional. Palp 10 - articled, as that of female, but with small gland-like swelling at mid-length of article 5.

A55BB523FFB5FF85FF7B269E08FAD99C.taxon	discussion	Remarks. The only previous record of Ascorhynchus constrictus was that of the female holotype of Stock (1997), collected at 799 – 850 m depth off Vanuatu; that specimen lacked the distal articles of the first pair of walking legs. The discovery of this male, with a complete left first leg has allowed the completion of the description of the species, as well as the description of sexual dimorphism. The male from Solomon Island is broadly similar to the female holotype, but bears conspicuous mid-dorsal setae on trunk segments 1 to 3; it is possible that these were detached in the holotype. Sexual dimorphism is shown by the presence of cement-gland pores in the femora of the posterior three pairs of legs, while the oviger is almost identical to that of the female, the seventh article being proportionately slightly longer. The legs of the first pair were incomplete on the holotype but the left front leg is entire on the present specimen. While the second, third and fourth legs are basically identical in morphology, the first legs (Fig. 1 C, drawn to the same scale as Fig. 1 D) are quite distinct, being 1.8 times as long as the third leg (stretched out), with a tarsus three-quarters as long as the second tibia, and without a main (or accessory) claws. The femur of the first leg is without cement-gland pores. Dimorphism of the legs is shown in a number of Ascorhynchus species: in those species with a one-article chelifore scape, the “ longitarsal ” group (tarsus more than half as long as propodus) includes A. bacescui Stock, 1975, A. ovicoxa Stock, 1975 A. utinomii Nakamura & Child, 1982, A. diethius Child, 2002, A glaberrimus Schimkewitsch, 1913, A. minutus Hoek, 1881 and A. auchenicus (Slater, 1879) with a reduced or “ tiny ” claw on the first legs, but only A. ramipes (Bohm, 1879) and the present species share extremely long first legs lacking a claw (see Child, 2002). A. ramipes is easily distinguished from A. constrictus in having low, rounded dorsodistal tubercles on the lateral processes, low tubercles above the chelifore insertion and in the dorsal trunk midline, and two tubercles on coxa 1 or the legs, inter alia.	en	Bamber, Roger N (2011): The male of Ascorhynchus constrictus Stock, 1997 (Arthropoda: Pycnogonida), with further new records of deep-sea pycnogonids from New Caledonia, the Solomon Islands and Vanuatu.

A55BB523FFB7FF83FF7B230308B8DFB7.taxon	discussion	Remarks. The damage to the anterior of this specimen, and the resulting absence of proboscis or chelifores, precludes complete description and thus naming of this evidently undescribed species, particularly as the number of articles in the chelifore scape is important in the classification of this genus. There are only three described brevitarsal species of Ascorhynchus with rounded median trunk tubercles but no ornamentation on the lateral processes. A. castelli (Dohrn, 1881), a shallow-water Mediterranean and western Atlantic species, differs from the present species in having setose tubercles on the first coxae, much less attenuate tibiae, and no pointed spire on the ocular tubercle, inter alia (e. g. Stock, 1974); A. castellioides Stock, 1957, a shallow-water species from the Gulf of Mexico and the Caribbean (Stock, 1957), is similarly a compact species with much less attenuate tibiae, and distal palp articles little longer than wide; both are without long curved setae on the abdomen or tibia 1. The present species is perhaps closest to A. melwardi Flynn, 1929, a shallow-water species from Indonesia, Singapore and eastern Australia, but that species has the ocular tubercle towards the anterior of the cephalon, long setae on the middorsal trunk tubercles, again has much less attenuate tibiae, and is “ extremely spinous ” (Flynn, 1929) with fine spines along anterior and posterior margins of the lateral processes. This specimen, one of the ten Ascorhynchus species now recorded from Melanesian waters, thus clearly represents an undescribed species, but must await the collection of an anteriorly-complete specimen before completion of its description and its naming.	en	Bamber, Roger N (2011): The male of Ascorhynchus constrictus Stock, 1997 (Arthropoda: Pycnogonida), with further new records of deep-sea pycnogonids from New Caledonia, the Solomon Islands and Vanuatu.

A55BB523FFB2FF80FF7B27EC0D2ADE66.taxon	discussion	Remarks. This very large panoceanic species (adult body length about 25 mm) has been recorded before in the Melanesian region from New Caledonia and Vanuatu (Stock, 1991; 1997) at depths from 844 to 2110 m (globally 420 to 5200 m). However, recently Staples (2007) described Colossendeis tasmanica from the east coast of Australia, a species showing many similarities to C. colossea, with which it may have been confused in the past, and recorded in the present material off the Solomon Islands (see below). It is therefore possible that some of Stock’s (loc. cit.) earlier records from this region may in fact be C. tasmanica. Characteristically, amongst other differences tabulated by Staples (loc. cit.), the terminal oviger claw is fused in C. colossea (as in all the material listed above), but articulated in C. tasmanica.	en	Bamber, Roger N (2011): The male of Ascorhynchus constrictus Stock, 1997 (Arthropoda: Pycnogonida), with further new records of deep-sea pycnogonids from New Caledonia, the Solomon Islands and Vanuatu.

A55BB523FFBCFF8EFF7B27EB0DD7DF45.taxon	discussion	Remarks. Colossendeis tasmanica was distinguished only recently by Staples (2007): it is similar in morphology to C. colossea, but can be distinguished by the articulation of the distal oviger claw (see under C. colossea above). The type and only previous material was from eastern Australia, so the present specimens extend the known range significantly further north. It is likely that re-examination of material identified previously as C. colossea may show the present species to be substantially more widespread in its distribution.	en	Bamber, Roger N (2011): The male of Ascorhynchus constrictus Stock, 1997 (Arthropoda: Pycnogonida), with further new records of deep-sea pycnogonids from New Caledonia, the Solomon Islands and Vanuatu.
