The new Australasian goblin spider genus Prethopalpus (Araneae, Oonopidae)
No full textThe new goblin spider genus Prethopalpus is restricted to the Australasian tropics, from the lower Himalayan Mountains in Nepal and India to the Malaysian Peninsula, Indonesia, Papua New Guinea, and Australia. Prethopalpus contains those species with a swollen palpal patella, which is one to two times the size of the femur, together with a cymbium and bulb that is usually separated, although it is largely fused in four species. The type species Opopaea fosuma Burger et al. from Sumatra, and Camptoscaphiella infernalis Harvey and Edward from Western Australia are newly transferred to Prethopalpus. The genus consists of 41 species of which 39 are newly described: P. ilam Baehr (♂, ♀) from Nepal; P. khasi Baehr (♂), P. madurai Baehr (♂), P. mahanadi Baehr (♂, ♀), and P. meghalaya Baehr (♂, ♀) from India; P. bali Baehr (♂), P. bellicosus Baehr and Thoma (♂, ♀), P. brunei Baehr (♂, ♀), P. deelemanae Baehr and Thoma (♂), P. java Baehr (♂, ♀), P. kranzae Baehr (♂), P. kropfi Baehr (♂, ♀), P. leuser Baehr (♂, ♀), P. magnocularis Baehr and Thoma (♂), P. pahang Baehr (♂), P. perak Baehr (♂, ♀), P. sabah Baehr (♂, ♀), P. sarawak Baehr (♂), P. schwendingeri Baehr (♂, ♀), and P. utara Baehr (♂, ♀) from Indonesia and Malaysia; and P. alexanderi Baehr and Harvey (♂), P. attenboroughi Baehr and Harvey (♂), P. blosfeldsorum Baehr and Harvey (♂), P. boltoni Baehr and Harvey (♂, ♀), P. callani Baehr and Harvey (♂, ♀), P. cooperi Baehr and Harvey (♂), P. eberhardi Baehr and Harvey (♂, ♀), P. framenaui Baehr and Harvey (♂, ♀), P. humphreysi Baehr and Harvey (♂, ♀), P. kintyre Baehr and Harvey (♂), P. scanloni Baehr and Harvey (♂), P. pearsoni Baehr and Harvey (♂), P. julianneae Baehr and Harvey (♂), P. maini Baehr and Harvey (♂, ♀), P. marionae Baehr and Harvey (♂, ♀), P. platnicki Baehr and Harvey (♂, ♀), P. oneillae Baehr and Harvey (♂), P. rawlinsoni Baehr and Harvey (♂), and P. tropicus Baehr and Harvey (♂, ♀) from Australia and Papua New Guinea. Three separate keys to species from different geographical regions are provided. Most species are recorded from single locations and only three species are more widely distributed. A significant radiation of blind troglobites comprising 14 species living in subterranean ecosystems in Western Australia is discussed. These include several species that lack abdominal scuta, a feature previously used to define subfamilies of Oonopidae

Baehr, et al. 8–18 Sep. 2015, vertebrate traps; 1 male (QM-S96340) same as previous. Etymology. The specific name is a noun in apposition taken from the type locality.

Ariadna kiwirrkurra can be separated from A. decatetracantha Main, 1954 in having a fovea as an indented pit (A. decatetracantha has no fovea); from A. thyrianthina Simon, 1908 by the oval opisthosoma (opisthosoma cylindrical in A. thyrianthina); from Ariadna burchelli (Hogg, 1900) by the absence of any opisthosomal pattern (A. burchelli has an opisthosomal pattern); from A. octospinata (Lamb, 1911) by PME in line of PLE (PME placed behind the line of PLE in A. octospinata) and from A. dysderina L. Koch, 1873 by the round PME (PME oval in A. dysderina).

Cavisternum barthorum Baehr & Harvey & Smith 2010, new species
No full textCavisternum barthorum, new species Figures 11, 87–89, map 2 TYPE: AUSTRALIA: Queensland : Male holotype from 23 km ESE of Cloncurry near Bishop Creek, 20 ° 47 9 05 0 S, 140 ° 42 9 49 0 E, 210 m (29 June–9 Sep. 2006, R. Raven, B. Baehr, A. Amey) (PBI_OON 00006073), deposited in QM (S75110). ETYMOLOGY: The specific name is a patronym in honor of Heidemarie Barth and her family. DIAGNOSIS: Males of C. barthorum resemble those of C. foxae, with the sternal concavity occupying the whole sternal length (fig. 11) and the epigastric scutum not protruding. However, males of C. barthorum can be easily separated by the rounded anterior margin of the clavate field (fig. 11) and the ovoid cymbium-bulb complex, with a smoothly, medially bent, corkscrew-shaped embolus (figs. 87–89). MALE: Total length 1.08. Carapace 0.49 long, 0.37 wide; abdomen 0.59 long, 0.25 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum longer than wide, with oval field of clavate setae reaching anterior margin, covering about 4 = 5 of sternum length and about K of sternum width, anterior margin with rounded edges, with bare median band (fig. 11). Cheliceral fang elongated, fangs extremely long, thin, bent, and crossed (fig. 11). Abdomen ovoid, epigastric scutum not protruding. Cymbiumbulb complex ovoid with a broadly based and corkscrew-shaped embolus (figs. 87–89). FEMALE: Unknown. DISTRIBUTION: This species is found only at the type locality, in western Queensland (map 2).Published as part of Baehr, Barbara C., Harvey, Mark S. & Smith, Helen M., 2010, The Goblin Spiders of the New Endemic Australian Genus Cavisternum (Araneae: Oonopidae), pp. 1-40 in American Museum Novitates 3684 on page 18, DOI: 10.1206/667.1, http://zenodo.org/record/535876

No full textCavisternum noelashepherdae, new species Figures 22, 158–160, map 3 TYPE: AUSTRALIA: Northern Territory : Male holotype from Calvert Hills Station, 49 km W of Calvert Road turnoff, 16 ° 49 9 23 0 S, 137 ° 08 9 57 0 E, 150 m (6 July–14 Sep. 2006, R. Raven, B. Baehr, A. Amey) (PBI_OON 00006104), deposited in QM (S75164). ETYMOLOGY: The specific name is a patronym in honor of Noela Helene Shepherd. DIAGNOSIS: Males of C. noelashepherdae resemble those of C. ewani, with the sternal concavity occupying most of the sternal length (fig. 22). However, males of C. noelashepherdae can be easily separated from all other species by their greatly reduced fangs (fig. 22), the endites with medially directed triangular lobes (fig. 22) and the row of stiff setae near the anterior margin of the clavate field (fig. 22). MALE: Total length 0.99. Carapace 0.49 long, 0.37 wide; abdomen 0.50 long, 0.29 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum longer than wide, median concavity occupying most of sternal length, with field of clavate setae covering about half of sternum width, median band bare, anterior margin with rectangular rim of short, stiff setae (fig. 22). Chelicerae straight, fang directed medially, reduced, tip unmodified. Endites with medially directed triangular lobes. Abdomen ovoid, epigastric scutum slightly protruding; sperm pore surrounded by circular field of pores. Cymbium-bulb complex bearing a long, medially bent embolus with a broadened basis (figs. 158–160). FEMALE: Unknown. DISTRIBUTION: This species is known only from Calvert Hills Station in northeastern Northern Territory (map 3).Published as part of Baehr, Barbara C., Harvey, Mark S. & Smith, Helen M., 2010, The Goblin Spiders of the New Endemic Australian Genus Cavisternum (Araneae: Oonopidae), pp. 1-40 in American Museum Novitates 3684 on pages 34-36, DOI: 10.1206/667.1, http://zenodo.org/record/535876

TYPE: Male holotype, Museum Paris AR 5730, identified as 2702 Ischnothyreus peltifer E. S. Ceylon. ETYMOLOGY: The specific name is a patronym in honor of Eugène Simon, who misidentified this species as Ischnothyreus peltifer (Simon, 1891), in his paper from 1893 in which a drawing of the male palp was published. DIAGNOSIS: Males can easily be recognized by the ventrally greatly bulged bulb and the inverted T-shaped distal end in dorsal view (fig. 168). MALE (PBI_ OON 23343, figs. 336–342): Total length 1.41. Carapace, sternum, chelicerae, endites, and labium pale orange. Eyes all subequal; ALE-PLE separated by less than ALE radius, PME touching throughout most of their length. Chelicerae slightly divergent; Abdomen: dorsal scutum pale orange, covering more than 3 ⁄ 4 of abdomen length, more than 1 ⁄ 2 to most of abdomen width, not fused to epigastric scutum, middle surface finely reticulate, sides finely reticulate; postepigastric scutum pale orange, almost rectangular, covering about 3 ⁄ 4 of abdominal length. Legs: yellow; patella plus tibia I near as long as carapace. Palp pale orange; patella: L, 0.37; P, 0.23; C, 0.62; H, 0.13; L/ H, 2.8; bulb ventrally greatly bulged bulb and the inverted T-shaped distal end in dorsal view and broad retrolaterally directed fold (figs. 167–169, 340–342). FEMALE: Unknown. OTHER MATERIAL EXAMINED: None.

DIAGNOSIS: Males of C. toadshow resemble C. foxae in having a long sternal concavity, but the patch of clavate setae is anteriorly oval in C. toadshow, does not reach the anterior margin, and is without a median band (fig. 24); the fangs are long and crossed with laterally directed tips (fig. 24). Females can be easily distinguished from all other Cavisternum species by their rectangular dark epigastric field (fig. 169). MALE: Total length 1.15. Carapace 0.50 long, 0.39 wide; abdomen 0.65 long, 0.33 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow.
