Siamaxonopsis Smit 2016, n. gen.
No full textGenus Siamaxonopsis n. gen. Diagnosis — Dorsal and ventral shields present. Dorsal shield fused anteriorly with ventral shield. Dorsal shield with A2, postocularia and four pairs of glandularia, the most posterior pair flanking the excretory pore (the latter fused with dorsal shield) and visible only in posteromedial view. Anterior coxal plates not extending to anterior idiosoma margin, without hook-like structures. Anterior to fourth leg sockets a ridge extending to lateral idiosoma margin. Between fourth leg sockets and genital field with two pairs of glandularia, lying closer to genital field than to fourth leg sockets. Genital field numerous pairs of acetabula. P2 with a large nose-shaped extension. Type species — Siamaxonopsis ypsilon n. sp. Remarks — The only known axonopsine genus with more than three or four pairs of acetabula is Omanaxonopsis Smit and Peši´c, 2010. However, this genus has one pair of glandularia between the fourth leg sockets and the genital field, has no dorsal glandularia flanking the excretory pore, has a truncate lateral projection of the ventral shield and leg claws with dorsal and ventral clawlets (Smit and Peši´c 2010).Published as part of Smit, H., 2016, The water mite family Aturidae Thor, 1900 from Southeast Asia (Acari: Hydrachnidia) with the description of one new genus and 14 new species, pp. 341-365 in Acarologia 56 (3) on page 360, DOI: 10.1051/acarologia/20162248, http://zenodo.org/record/539384

No full textJavalbia rotunda n. sp. (Figure 11) Material examined. Holotype male, Stream near Haewsai Waterfall, Nam Nao NP, Thailand, 16°40.668N 101°41.856E, alt. 425 m a.s.l., 16-xi-2007. Diagnosis — A2 not fused with dorsal shield; postocularia lying anteromedially of dgl-1; dgl-4 absent, only associated setae present; anterior coxae close to anterior idiosoma margin; gonopore nearly rounded. Description — Male: Idiosoma yellowish, dorsally 421 long and 275 wide, ventrally 413 long. Dorsal shield 405 long and 235 wide; excretory pore fused with dorsal shield. A2 not fused with dorsal shield, postocularia lying anteromedially of dgl-1; dgl-4 absent, only associated setae present. Glandularia platelets in dorsal furrow small. Coxae lying far anteriorly, but not reaching anterior idiosoma margin. Coxal suture lines incomplete. Cxgl-4 lying closer to fourth leg sockets than to genital field. Genital field with three pairs of acetabula, fused with ventral shield. Gonopore nearly rounded, 44 long and 40 wide. Vgl-4 fused with ventral shield. Length of P1-5: 20, 40, 30, 56, 29. Length of I-leg-4- 6: 70, 68, 66 (till tip of segment).Length of IV-leg-4-6: 88, 96, 72. Legs without swimming setae. Female: Unknown. Etymology — Named for the nearly rounded gonopore. Remarks — Few Javalbiopsis species have the postocularia anteromedially of dgl-1: Javalbia kinabaluensis Smit and Peši´c, 2014 has the genital field separate from the ventral shield, J. magniseta Smit and Peši´c, 2014 has very large dorsal setae and the coxae lying less anteriorly, J. reticulata Smit and Peši´c, 2014 has a less rounded gonopore and dgl-2 and -3 without glandularia and J. nova n. sp. has dgl-4 with glandularia.Published as part of Smit, H., 2016, The water mite family Aturidae Thor, 1900 from Southeast Asia (Acari: Hydrachnidia) with the description of one new genus and 14 new species, pp. 341-365 in Acarologia 56 (3) on page 357, DOI: 10.1051/acarologia/20162248, http://zenodo.org/record/539384

Inside the gonopore two acetabula (?) are present, probably overlooked in the original description. These acetabula-like structures are also present in H. triscutata, and illustrated by Lundblad (1947) but not discussed. The posteromedial extension of the fourth coxae of H. palustris is of variable width, from very narrow as illustrated in the original description (Smit 1992) till much broader. The species is known from two localities in Queensland among which the type locality (Hasties Swamp) and one locality in Western Australia.Published as part of Smit, Harry, 2014, Australian water mites of the genus Hydrachna Müller, with the description of five new species (Acari: Hydrachnidia: Hydrachnidae), pp. 170-186 in Zootaxa 3827 (2) on page 181, DOI: 10.11646/zootaxa.3827.2.3, http://zenodo.org/record/22523
Aspidiobates unidorsalis Smit 1992
No full textAspidiobates unidorsalis Smit, 1992 Material examined. Holotype male, Darraboola Creek, Lamington NP, Queensland, Australia, 19-vii-1989, leg. H. Smit (S.21120, QM—palp mounted, idiosoma missing). Remarks. As the idiosoma is missing (in the past the holotype was sent from Amsterdam to Brisbane, but upon arrival in Brisbane the idiosoma was lacking), I was able to examine the palp only. Based on the original description, dgl-1 and dgl-2 are at equal distance, with the postocularia anterior to dgl-1. The palp is slender, without setal tubercles and a distinct anteroventral extension of P2. In juvenile Aspidiobates specimens the dorsal and ventral shields are not yet developed, and the dorsal shield appears as entire. As Smit (1992) mentioned the presence of dorsal and ventral shields are present, the holotype is not a juvenile specimen. The only other Australian Aspidiobates species with an entire dorsal shield is A. bidewel Harvey & Cook, 1988, but this species has dgl-1 and the postocularia at the same level and the distance of dgl-1 and dgl-2 is much larger than the distance of dgl-2 and dgl-3 (only slightly larger in A. unidorsalis). Moreover, the male fourth leg of A. bidewel is modified (not modified in A. unidorsalis).Published as part of Smit, Harry, 2019, The water mite genus Aspidiobates Lundblad, 1941 from Australia (Acari: Hydrachnidia: Hygrobatidae) with the description of two new species, pp. 115-122 in Zootaxa 4550 (1) on page 121, DOI: 10.11646/zootaxa.4550.1.5, http://zenodo.org/record/262517
Vicinaxonopsis costata Smit 2016, n. sp.
No full textVicinaxonopsis costata n. sp. (Figure 15) Material examined — Holotype female, Thorntip Waterfall, Kaeng Krachan NP, Thailand, 12°50.952N 99°18.498E, 29-xi-2007. Diagnosis — Eyes absent, venter with distinctive longitudinal ridges. Description — Female: Idiosoma brown coloured, dorsally 489 long and 373 wide, ventrally 467 long; eyes absent. Dorsal shield fused anteriorly with ventral shield, 373 wide; excretory pore fused with dorsal shield. Dorsal shield with A2, postocularia and four pairs of glandularia; due to rugosity of integument associated setae of dorsoglandularia not visible. Body pores of integument arranged in a rounded pattern in anterior part of dorsal shield; anterior part of dorsum with two pairs of large lateral papillae. Anterior coxae not extending to anterior idiosoma margin. Coxal suture lines obliterated. Apodemes of gnathosoma very long. Anterior to the fourth leg sockets a ridge extending to the lateral idiosoma margin. Venter with numerous distinctive longitudinal ridges. Between fourth leg sockets and genital field two pairs of glandularia, lying close to each other. Genital field with three pairs of acetabula; gonopore 60 long and 46 wide. Length of P1-5: 30, 50, 24, 50, 53. P4 stocky and ventrally somewhat bulging, with a long ventral seta; P5 long and slender. Length of I-leg-4-6: 52, 54, 56 (till tip of segment). Length of IV-leg-4-6: 80, 78, 56. Numbers of swimming setae: IV-leg-4 one, IV-leg-5 two. Male: Unknown. Etymology — Named for the distinctive ridges of the venter. Remarks — The combination of absence of eyes and the presence of longitudinal ridges is characteristic for the new species. Vicinaxonopsis caeca (Smit and Peši´c, 2014) from Borneo has reduced lateral eyes and a different patterns of the anterior dorsal shield (Smit and Peši´c 2014). Despite the absence of eyes, the distinctive brown colour of the idiosoma shows that this species is not hyporheic.Published as part of Smit, H., 2016, The water mite family Aturidae Thor, 1900 from Southeast Asia (Acari: Hydrachnidia) with the description of one new genus and 14 new species, pp. 341-365 in Acarologia 56 (3) on pages 362-364, DOI: 10.1051/acarologia/20162248, http://zenodo.org/record/539384
Interview with Zus Haagen-Smit
No full textThis interview in 2000 with Zus (Maria) Haagen-Smit, widow of Caltech biologist Arie Jan Haagen-Smit (1900-1977), describes their early education at the University of Utrecht, his work on terpenes with Leopold Ruzicka, and the cooperation between Caltech and Utrecht in studies of plant hormones. In 1936, as war loomed in Europe, Arie Haagen-Smit was invited for a year to Harvard by Kenneth Thimann; in 1937, he was invited by T. H. Morgan to join the faculty of Caltech's Biology Division, where he continued his work on terpenes and plant hormones. Recollections of Dutch group at Caltech: Frits Went, Herman Dolk, Johannes van Overbeek, and Anthonie van Harreveld. Advent of World War II; opening of butadiene plant in Los Angeles, 1943, and consequent smog problems in Los Angeles. She recalls her husband's pioneering work in analysis of smog and measures to reduce it; and his consultancies with L.A. County Air Pollution Control District, Southern California Edison Co., auto industry, and California Air Resources Board. She reads extensively from Arnold Beckman's tribute to him and the history of Los Angeles County's battle to reduce air pollution. Summarizes the awards and honors he received toward the end of his life

Legs: dL of I-L-5–6: 88, 89; I-L-6 H 32, dL/H I-L-6 ratio 2.76. Male: unknown. Etymology. Named after Sunda Shelf; major landmasses on the shelf include the Malay Peninsula, Sumatra, Borneo, Java, Madura, Bali and their surrounding smaller islands. Discussion. The subgenus Allotorrenticola includes six species from Asia, i.e., Neoatractides abnormipalpis (Lundblad, 1941) (Burma, Malaysia, Brunei; Wiles 1997), N. bahtilli (Wiles, 1991) (Malaysia, Thailand; Wiles 1997, Pešić & Smit 2009a), N. malayensis (Wiles, 1991) (Malaysia, Thailand; Wiles 1997, Pešić & Smit 2009a), N. suvarna (Cook, 1967) (India, Cook 1967), N. farmerae Wiles, 1999 (Borneo, Wiles 1999) and N. calidus Pešić & Smit, 2012 (South Iran, Pešić et al. 2012a), and N. erato Pešić & Smit, 2014 (West Africa, Pešić & Smit 2014). The shape of dorsal shield with the shoulder platelets fused to the large dorsal plate, makes the new species most similar to Neoatractides erato, a species recently described from Ghana (Pešić & Smit 2014). The latter species can easily be distinguished by the series of different character states: gnathosoma with conspicuous oral papillae (sensu Wiles 1997), P-2 maximum height at distal margin, P-3 stout with short ventral seta located in the distal half, P-4 almost equal in length with P-3, cheliceral claw relatively long, gnathosomal bay moderately deep (see Pešić & Smit 2014). Two Allotorrenticola species previously reported from Borneo (Wiles 1999), N. abnormipalpis and N. farmerae can easily be distinguished from N. sundaensis n. sp. in addition to the shoulder platelets not fused to the large dorsal plate, by P-1 partially fused with P-2 (see Wiles 1999). Habitat. Sandy/bouldery streams, shaded by rain forest (Fig. 43D). Distribution. Borneo; known only from the locus typicus.
