Macropes bambusiphilus Zheng & Zou, 1982b, 3, 117–118; Hua, 2000, 190. New synonymy Macropes slateri Zheng & Wang, 1987, 6, 66–67. New synonymy
This is a robust species of the Macropes femoralis complex; the habitus is similar to M. uniformis, but larger (5.7 vs. 4.14); the pronotal pubescence is denser; the scutellar non-pruinose area is narrow, confined to the narrow mesal T-shape elevation. It may be separated from M. complanus sp. nov. and M. harringtonae by the characters mentioned in the diagnosis of the new species or as given in the key. Pygophore opening and paramere as shown in Zheng (1982a).
The abdomen of the holotype of M. bambusiphilus Zheng & Zou was missing. We examined the remnants of the holotype, found the pronotum of M. bambusiphilus a little more heavily built than M. robustus; apart from this, there are no distinct difference between these two species.
The genital segments of the holotype of M. slateri Zheng & Wang were missing. The pronotum of the holotype of M. slateri is a little more slender than that of M. robustus. The holotype of M. bambusiphilus and M. slateri are of the same series of specimens, both collected from Mengla, Yunnan, China in September 20 to 25, 1979. When we examined the specimens of these three species, we found that there were transitional forms of pronotum. Here we treat both of M. bambusiphilus and M. slateri as junior synonymies of M. robustus.

Porrorhynchus

description: Porrorhynchus (Subgenus Rhomborhynchus) Ochs, 1926
Discussion. Porrorrynchus species are relatively narrow, angulate, beautifully streamlined gyrinids that are very infrequently encountered along the streams of New Guinea, generally in gravel bottomed creeks and rivers at low to intermediate elevations. In such habitats, they are occasionally syntopic with Dineutus (Rhombodineutus) species. The last taxonomic treatment of Porrorhynchus for New Guinea by Ochs (1955) recognized a single species, Porrorhynchus (Rhomborhynchus) depressus, which was divided into 5 subspecies based on a very limited number of specimens. In aggregate, these subspecies occur throughout New Guinea, and on the closely proximal island of Misool to the west. Large series of two of these subspecies have recently been collected, and are reported below.

Material examined. PAPUA NEW GUINEA, Gulf Prov.: 21 males, 20 females, Kikori River basin, Omo River at Omo, 40 m. [1310 ft.], 6°58'41"S, 144°18'15"E, water temp. 24° C., 28 February 1995, 09:30-14:00 hrs., CL 7001, D. A. Polhemus (BPBM).
Discussion. The holotype male of the nominate subspecies of Porrorhynchus (Rhomborhynchus) depressus was collected by Loria in 1890 at Dilo, on the Kemp Welch River in what is now southern Papua New Guinea (Ochs, 1955), and a second specimen was noted by Ochs (1955) from the Astrolabe Range, near Port Moresby. The species has apparently not been documented since. The new collection reported below comes from the lower Kikori River system, extending the range of this subspecies well to the west (Fig. 1), and implies that this nominate subspecies of P. (R.) depressus may occur in the lower sections of the intervening Purari River basin as well.
The Omo River at the point where this species was collected was a moderately large, smoothly flowing lowland river. The bed consisted mostly of water-rounded cobbles, with alternating riffles and flowing pools, moderately well shaded by disturbed lowland rain forest interspersed with sago palms. Based on known collections, this subspecies occupies the Papuan Gulf Foreland area of freshwater endemism (Area 28) as defined by Polhemus & Allen (2007).
This is the species listed as “ Porrorhynchus sp.” in Polhemus (1995).

Dineutus (Rhomborhynchus) depressus misoolensis Ochs, 1955: 135.
Material examined. INDONESIA, Papua Prov. [= former Irian Jaya Prov.]: 6 males, 15 females, Misool Is., central interior, Tama River, upper trib. to Kasim River, SE of former Fakal village site, 60 m. [200 ft.], 1°51'38.1"S, 129°55'24.1"E, water temp. 26.5° C., 22 April 1999, 10:30–14:30 hrs., CL 7110, D. A. Polhemus (USNM).
Discussion. This subspecies is apparently endemic to the island of Misool (Fig. 1), and was previously recorded in the literature only from the type series (Ochs, 1955). The new record provided below also comes from this island, and based on known collections, this subspecies is confined to the Misool area of freshwater endemism (Area 3) as defined by Polhemus & Allen (2007).
This taxon was taken on Misool at the Tama River, a broad, clear, upland river flowing at moderate speed through alternating riffles and pools in a bed of metamorphic and sedimentary cobbles and gravels, with the channel margins partly shaded by intact upland rain forest. Although many other streams on Misool were sampled during a survey in 1999, individuals of P. depressus misoolensis were found only at this locality, which was also the only collecting site to lie along a stream reach flowing through non-carbonate rocks. Misool is largely an upraised limestone platform, but has a central ridge of metamorphics and sandstones, and it is possible that underlying petrology may influence stream water chemistry and substrate characteristics, and thus the distribution of this gyrinid taxon on Misool.

Dineutus

description: Dineutus (Subgenus Rhombodineutus) Ochs, 1926
Discussion. Rhombodineutus species are moderate sized, broadly ovate gyrinids that are typical inhabitants of rocky upland streams in the foothill and lower montane zones of New Guinea. They may also occur in lowland alluvial forests, but only along the inner margins of alluvial outwash plains where the creeks still retain a reasonable rate of flow velocity upon exiting the adjacent mountain foothills. Species are generally intermittent in their distribution, but often quite abundant along the reaches where encountered. Up to three species may occur at a given site, although in most instances only a single species will be present.

Dineutus (Rhombodineutus) pectoralis: Ochs, 1926: 140.
Material examined. INDONESIA, Papua Prov. [= former Irian Jaya Prov.]: 8 males, 10 females, Vogelkop Peninsula, Arfak Mountains, small rocky stream at Aimasi Hulu, 65 km. SW of Manokwari, 140 m. [450 ft.], water temp. 25° C., 19 Oct. 1991, CL 2649, [0°53'49"S, 133°47'55"E], D. A. and J. T. Polhemus (BPBM).
Discussion. This nominate subspecies of D. (R.) pectoralis has been taken only in the northeastern section of the Vogelkop Peninsula of western New Guinea (Brinck, 1983). In preparing his revision of New Guinea Rhombodineutus, Brinck (1983) was able to study only the single male holotype taken by d’Albertis at Andai in 1872. The new series below thus greatly increases the documented material for this taxon, and extends the range slightly to the west, into interior Vogelkop (Fig. 2). The specimens were taken from a small, clear stream emerging from primary rain forest along the foothills of the Arfak Mountains into an adjacent oil palm plantation. This stream was 0.25–0.50 m. deep, flowing over a bed of igneous rocks and sand through a set of quiet pools alternating with riffles and small cascades.
Based on known collections, this subspecies occupies the Vogelkop Highlands area of freshwater endemism (Area 5) as defined by Polhemus & Allen (2007).

Material examined. INDONESIA, Papua Prov. [= former Irian Jaya Prov.]: 3 males, 15 females, Biak Is., Faknidi River (trib. to Wari River) at Faknidi, 150 m. [500 ft.], 0°53'32"S, 135°59'23"E, water temp. 25.5 °C., 12 January 1997, 14:30–15:30 hrs., CL 7038, D. A. Polhemus (USNM).
Discussion. This subspecies is apparently endemic to the island of Biak (Fig. 2), and was previously known from a total of 6 specimens, the majority taken by J. L. Gressit at Kampong Landbouw (Brinck, 1983), a locality not found on maps but noted by Gressitt as being near the center of the island.
More recent collections have come from the Faknidi River, which was a relatively slow flowing stream with a bed of sand, gravel and cobbles, partially shaded by disturbed upland rain forest growing on a limestone plateau. The gyrinids were taken from a large, deep pool formed at a road crossing. Based on known collections, this subspecies occupies the Biak/Supiori area of freshwater endemism (Area 8) as defined by Polhemus & Allen (2007).

Discussion. As with Dineutus (Rhombodineutus) heurni, this species was described from material collected by the Archbold Expeditions in the mountains to the south of the Idenberg River in west-central New Guinea. New collections now extend the range of this species westward into the Wapoga River Basin (Fig. 4), where it occurs at elevations slightly lower than those at which D. heurni was encountered (see Table 1).
For ecological notes on this species see the discussion under D. heurni, with which this species is occasionally syntopic at elevations below 300 m. Based on known collections, this species occupies the Mamberamo Foreland area of freshwater endemism (Area 17) as defined by Polhemus & Allen (2007).
This species, in combination with Dineutus (Rhombodineutus) tetracanthus tetracanthus and Dineutus (Rhombodineutus) heurni, was grouped under the composite listing of “ Rhombodinetus sp. undet.” from Station 50 in Polhemus (2000).

Material examined. INDONESIA, Papua Prov. [= former Irian Jaya Prov.]: 4 males, 20 females, rocky stream at PTFI Helipad 60, NE of the head of Etna Bay, 90 m. [300 ft.], 3°56'55"S, 134° 59'02"E, water temp. 24.5° C., 30 March 1997, 08:00–09:45 hrs., CL 7080, D. A. Polhemus (USNM).
Discussion. This species was previously known only from the original type series of 7 specimens collected at Etna Bay in 1904 (Brinck, 1983). New collections area at hand from the same drainage basin (Fig. 5), indicating that D. silenus may be locally endemic to Etna Bay and the immediately surrounding region. Based on captures to date, this species occupies the Vogelkop Anticlines area of freshwater endemism (Area 6) as defined by Polhemus & Allen (2007).
The Helipad 60 collecting site consisted of a moderately small, clear stream flowing in a partially shaded bed of cobble and gravel in a small, tight valley amid the steep hills behind Etna Bay. The locality, which was accessed by helicopter, was also a geology field survey camp for P. T. Freeport Indonesia (PTFI) mining company. This is the species listed as “ Rhombodineutus sp. undet.” in Polhemus (1998).

Discussion. This taxon has a rather broad distribution in the northwestern portion of the main body of New Guinea, occurring from the Bewani and Cyclops Mountains westward along the margins of the Mamberamo Basin to the Wapoga River Basin (Fig. 5).
The Tiri River locality near Dabra at which this species was taken was a moderately swift, sand bottomed stream with pools 0.5–1.5 m. deep, alternating with shallow cobble riffles. The channel width varied from 2– 5 m., with the central portion of the channel unshaded, and the margins half shaded by undisturbed lowland rain forest. For a description of the Tirawiwa River locality listed below see the discussion under Dineutus (Rhombodineutus) heurni. At this latter site, Dineutus (Rhombodineutus) tetracanthus was syntopic with both Dineutus (Rhombodineutus) heurni and Dineutus (Rhombodineutus) sinuaticollis. Based on known collections, this subspecies occupies the Mamberamo Foreland area of freshwater endemism (Area 17) as defined by Polhemus & Allen (2007).
This species, in combination with Dineutus (Rhombodineutus) heurni and Dineutus (Rhombodineutus) sinuaticollis, was grouped under the composite listing of “ Rhombodinetus sp. undet.” from Station 50 in Polhemus (2000).

[3500 ft.], 3°08'41"S, 136°34'25"E, water temp. 19° C., 19 April 1998, 08:00–12:00 hrs., CL 7101, D. A. Polhemus (USNM); 1 male, Wapoga River basin, rocky rainforest tributary to upper Ziwa River at PTFI Wapoga Alpha drilling camp, 1050 m. [3500 ft.], 3°08'41"S, 136°34'25"E, water temp. 20° C., 18 April 1998, 10:00–17:00 hrs.; 19 April 1998, 14:00–18:00 hrs., CL 7100, D. A. Polhemus (USNM).
Discussion. This large species was previously known from the Mamberamo River basin; the new records extend the range of this species into the Wapoga River basin immediately to the west (Fig. 6).
For notes on the Ziwa River locality where this species was taken see the discussion under Dineutus (Rhombodineutus) heurni. In addition to being collected along the main river at this locality, specimens were also collected from a moderately small, clear tributary stream, less than 1 m. deep, with flowing pools, riffles and small cascades partially shaded by tall stature montane rain forest. On this creek, the gyrinids were taken along an open, gravel-bottomed reach bordered by quiet side pools. Based on known collections, this species occupies the West Papuan Central Highlands area of freshwater endemism (Area 20) as defined by Polhemus & Allen (2007).
This is the species listed as “ Merodineutus sp. undet” from sampling stations 56–58 in Polhemus (2000).

Discussion. This very large species is widely distributed at higher elevations in the Owen Stanley Range (Fig. 6). At the Om Creek locality this species was found on a moderately swift, clear creek traversing a cleared valley floor in a bed of dark, water-rounded rocks and boulders, bordered by steep, grassy banks and partially shaded by remnant trees. The water here was 0.3–1.0 m. deep, occupying a channel 2– 3 m. wide, with the gyrinids occurring on shaded pools.
Based on known collections, this subspecies occupies the Owen Stanley Mountains area of freshwater endemism (Area 31) as defined by Polhemus & Allen (2007). The records above were also provided in Kraus et al. (2006).

Discussion. Members of this subgenus are moderately small gyrinids with spinose projections on the posterior margins of the elytra, and occur across a range of habitats in New Guinea, from swampy lowlands to rocky upland mountain streams. Because the constituent species exhibit broad distributions within such zones and do not exhibit strong regional endemism, they are not informative in regard to the areas of freshwater endemism defined by Polhemus & Allen (2007)

Discussion. This species is widespread across the northern margin of Australia and in southern New Guinea. The record below is the first from rivers draining to the Arafura Sea between the Merauke and Etna Bay, and fills a major gap in the distribution records for this taxon (Fig. 8).
This is the species listed as “ Dineutes neohollandicus ” in Polhemus & Polhemus (1998).

Discussion. This species is widely distributed in the Owen Stanley Range (Fig. 7), but appears to prefer elevations slightly lower than those inhabited by Dineutus (Merodineutus) macrochirus, with which it is occasionally syntopic. At the Hane River locality this species was taken from a swift, clear mountain creek running in a bed of water-rounded boulders and cobbles, with a water depth of 1.0–1.5 m. and a channel width of 3– 4 m.
Based on known collections, this species occupies the Owen Stanley Mountains area of freshwater endemism (Area 31) as defined by Polhemus & Allen (2007). The records above were also provided in Kraus et al. (2006).

Tumidochelia

description: Genus Tumidochelia Knight, Larsen & Heard, 2003
Diagnosis. Female (modified from Knight et al. 2003). Body elongate. Antennule article 1 shorter than rest of antennule, article 2 almost as long as article 1. Antenna with five or six articles, article 3 with or without fusion line. Mandible molar pointed but not quite as much as in Leptognathia, with small apical spines. Cheliped with inflated “shield-like” expansion of the inner distal side of the carpus. Pereopod 1 carpus shorter than merus Pereopods 1–3, propodus longer than dactylus and unguis combined. Pereopods 4–6, propodus longer, or as long as dactylus and unguis combined. Pleopods small but present. Uropod bearing spiniform distal process on inner margin of basal article; endopod and exopod each with 2 articles.
Male. Listed as ‘unknown’ by Knight et al. (2003) but one male is reported by Hansen (1913:84, pl.VIII, 4f–i) belonging to L. uncinata (transferred to Tumidochelia below). This male is of the ‘swimming male’ type with no functional mouthparts, reduced pereon, and multiarticulated antennule with multiple aesthetacs, but differing from the leptognathid male by a biarticulated uropodal exopod. It is not certain that his male belongs to Tumidochelia as other species (leptognathids) were found in the same sample.
Type species. Tumidochelia randyi Knight, Larsen & Heard, 2003 by monotypy.
Gender. Feminine.
Remarks. With the finding of the new species, described below, and the transfer of Leptognathia unicinata Hansen, 1913 and L. dentifera G.O. Sars, 1896 there can be no doubt as to the validity of the genus Tumidochelia. There is, however, some doubts as to the family designation of the genus. While currently placed in the family Colletteidae the genus is probably better placed in the Leptognathiidae but this transfer will have to await a comprehensive phylogenetic analysis. The basis for this statement is the pointed nature of the mandibular molar.

Material. Holotype, non-ovigerous female, (ZMUC CRU- 8518), Davis Strait, Ingolf Sta. 36, 61°50’N, 56°21’W, 2702 m. Paratype, 1 juvenile (ZMUC CRU- 9275), Ingolf Sta. 103, 66°23’N, 8°52’W, 1090 m.
Remarks. Leptognathia unicinata is transferred to Tumidochelia due to the special structure of the cheliped carpal shield and the biramous uropod with a spiniform process on the basal article. It also conforms to the other diagnostic characters: antennule article 1 shorter than rest of antennule, article 2 almost as long as article 1, and the pereopod 1 carpus shorter than merus.

Material. Syntypes, 8 non-ovigerous females, 1 ovigerous female, (NHMO F15188), Christiania Fjord (Olso Fjord) 113– 188 m.
Supplementary description (appendages of dissected paratype).
FEMALE.
Mouthparts. Labrum apex curved and setose (Fig. 3 A). Right Mandible (Fig. 3 B) incisor with three acute denticles. Labium (Fig. 3 C) with one pair of lobes, without process at outer corners. Maxillule (Fig. 3 D) endite with eight terminal spiniform setae of which two are setulose; palp not recovered. Maxilla (Fig. 3 E) narrow and fairly large (half as long as maxillule endite). Maxilliped (Fig. 3 F) endites with blunt distal process, fairly wide (almost as wide as basis). Basis fused. Palp article 1 naked; article 2 with two inner setae; article 3 with three inner setae; article 4 with four setae.
Cheliped (Fig. 3 G). Attachment via large sclerite. Basis naked, narrow in posterior part, approximately as long as carpus. Merus with one ventral seta. Carpus widening distally, with small dorsodistal seta and one simple ventrodistal seta, ventrodistal part inflated, extending distally past propodus articulation. Propodus shorter than basis, with two simple ventral setae mid-length, and three small distal setae proximal to dactylus. Fixed finger displaying two spines and three setae on inner margin. Dactylus naked.
Remarks. Tumidochelia dentifera is very close to T. knighti, but apart from the large distance between the type localities, the obvious fusion line on the antenna article 3 and the longer uropodal exopod of T. dentifera is sufficient to discriminate between these species.
As with the species above L. dentifera is here transferred to Tumidochelia due to the biramous uropod with a spiniform process on the basal article; the short antennule article 1 and long article 2. The cheliped carpal shield is not described (G.O. Sars 1896:30) and the illustration (G.O. Sars 1896:p.142, pl1) is not clear regarding this character. However, examination of the syntypes confirms the presence of this character (Fig. 3 G) in all specimens and we suspect that Sars illustrated the inner side of the cheliped, thus obscuring this character.

description: Biarticulata n. gen.
Diagnosis. Female. Cheliped fixed finger and dactylus simple. Uropodal exopod with two articles.
Etymology. The genus is named for the presence of a biarticulated uropodal exopod.
Remarks. The new leptognathidean genus Biarticulata is here erected to accommodate the species listed below. It is freely admitted that the phylogenetic evidence for erection of this genus is weak, as it is dependant on only one character (which is probably homoplastic). However, as a working taxon, this organization seems to work.
Most of the species in this genus are too poorly described to construct a key. Furthermore, all the slides of the species described by Kudinova-Pasternak have been lost (Dr. M. BłaŻewicz-Paszkowycz, pers. comm.). This unfortunate fact is severely obstructing any attempts to revise the Leptognathia complex.
This genus currently composes of: Leptognathia arctophylax (Norman & Stebbing, 1886); L. distincta Kudinova-Pasternak, 1981; L. elegans Kudinova-Pasternak, 1965; L. greveae Kudinova-Pasternak, 1976; L. mironovi Kudinova-Pasternak, 1981; L. parabranchiata Kudinova-Pasternak, 1977 *; L. paraelegans Kudinova-Pasternak, 1970; L. tuberculata (?) Hansen, 1913 and L. voeringi (G.O. Sars, 1877).
