Revision of Agathodesmus Silvestri, 1910 (Diplopoda, Polydesmida, Haplodesmidae)
Robert Mesibov
ZooKeys , 2009, DOI: 10.3897/zookeys.12.206
Abstract: Agathodesmus Silvestri, 1910 includes A. baccatus (Carl, 1926) comb. n. from New Caledonia, A. bucculentus (Jeekel, 1986) comb. n. from Queensland, Australia, and A. johnsi sp. n. and A. steeli Silvestri, 1910 (type species) from New South Wales, Australia. A. baccatus and A. bucculentus were formerly placed in Atopogonus Carl, 1926 syn. nov. The identity of the apparently congeneric Inodesmus jamaicensis Cook, 1896 sensu Loomis, 1969 from Jamaica is still uncertain, and Inodesmus Cook, 1896 remains a nomen inquirendum.
A specialist’s audit of aggregated occurrence records
Robert Mesibov
ZooKeys , 2013, DOI: 10.3897/zookeys.293.5111
Abstract: Occurrence records for named, native Australian millipedes from the Global Biodiversity Information Facility (GBIF) and the Atlas of Living Australia (ALA) were compared with the same records from the Millipedes of Australia (MoA) website, compiled independently by the author. The comparison revealed some previously unnoticed errors in MoA, and a much larger number of errors and other problems in the aggregated datasets. Errors have been corrected in MoA and in some data providers’ databases, but will remain in GBIF and ALA until data providers have supplied updates to these aggregators. An audit by a specialist volunteer, as reported here, is not a common occurrence. It is suggested that aggregators should do more, or more effective, data checking and should query data providers when possible errors are detected, rather than simply disclaim responsibility for aggregated content.
A remarkable case of mosaic parapatry in millipedes
Robert Mesibov
ZooKeys , 2011, DOI: 10.3897/zookeys.156.1893
Abstract: The parapatric boundary between Tasmaniosoma compitale Mesibov, 2010 and T. hickmanorum Mesibov, 2010 (Polydesmida: Dalodesmidae) in northwest Tasmania was mapped in preparation for field studies of parapatry and speciation. Both millipede species can be collected as adults throughout the year, are often abundant in eucalypt forest and tolerate major habitat disturbance. The parapatric boundary between the two species is ca 100 m wide in well-sampled sections and ca 230 km long. It runs from sea level to 600-700 m elevation, crosses most of the river catchments in northwest Tasmania and several major geological boundaries, and one portion of the boundary runs along a steep rainfall gradient. The location of the boundary is estimated here from scattered sample points using a method based on Delaunay triangulation.

Robert Mesibov
ZooKeys , 2012, DOI: 10.3897/zookeys.217.3809
Abstract: Three new genera and six new species of Pyrgodesmidae are described from Queensland: Asticopyrgodesmus gen. n., containing A. lamingtonensis sp. n. and A. maiala sp. n. (type species); Nephopyrgodesmus gen. n., with N. eungella sp. n. (type and only species); and Notopyrgodesmus gen. n., with N. kulla sp. n. (type species), N. lanosus sp. n. and N. weiri sp. n. Localities and specimen data are given in an Appendix for undescribed Australian Pyrgodesmidae occurring in wet forests from the Northern Territory south to New South Wales, and on Lord Howe Island.
Known unknowns, Google Earth, plate tectonics and Mt Bellenden Ker: some thoughts on locality data
Robert Mesibov
ZooKeys , 2012, DOI: 10.3897/zookeys.247.4195
Abstract: Latitude/longitude data in locality records should be published with spatial uncertainties, datum(s) used and indications of how the data were obtained. Google Earth can be used to locate sampling sites, but the underlying georegistration of the satellite image should be checked. The little-known relabelling of a set of landmarks on Mt Bellenden Ker, a scientifically important collecting locality in tropical north Queensland, Australia, is documented as an example of the importance of checking records not accompanied by appropriately accurate latitude/longitude data.
New species of Prosopodesmus Silvestri, 1910 (Diplopoda, Polydesmida, Haplodesmidae) from Queensland, Australia
Robert Mesibov
ZooKeys , 2012, DOI: 10.3897/zookeys.190.3276
Abstract: Prosopodesmus crater sp. n., P. kirrama sp. n. and P. monteithi sp. n. are described from the Wet Tropics of north Queensland. The hothouse species P. panporus Blower & Rundle, 1980 is recorded from rainforest on Queensland’s Cape York Peninsula, where it is likely to be native.
New species of Asphalidesmus Silvestri, 1910 from Australia (Diplopoda, Polydesmida, Dalodesmidea)
Robert Mesibov
ZooKeys , 2011, DOI: 10.3897/zookeys.93.1255
Abstract: Asphalidesmus allynensis sp. n. and A. dorrigensis sp. n. are described from New South Wales, A. otwayensis sp. n. from Victoria, and A. bellendenkerensis sp. n., A. carbinensis sp. n., A. magnus sp. n. and A. minor sp. n. from Queensland. The previously endemic Tasmanian genus Asphalidesmus Silvestri, 1910 is now known from 16°S to 43°S in eastern Australia, a north-south range of ca 3000 km. Asphalidesmus spp. throughout this range are very similar in overall appearance. Three of the new species are able to coil in a tight spiral.
A new millipede genus and a new species of Asphalidesmus Silvestri, 1910 (Diplopoda, Polydesmida, Dalodesmidea) from southern Tasmania, Australia
Robert Mesibov
ZooKeys , 2009, DOI: 10.3897/zookeys.7.111
Abstract: Noteremus summus n. gen., n. sp. occurs at 1100-1300 m on the summit of Mt Weld, southern Tasmania, while its congener N. infimus n. sp. is troglobitic in caves in the Junee-Florentine karst, 30-40 km to the northwest. Like species of Paredrodesmus Mesibov, 2003 and Procophorella Mesibov, 2003, Noteremus spp. have a head + 19 rings, no sphaerotrichomes and pore formula 5, 7-18, and are not assigned to family within the suborder Dalodesmidea. Asphalidesmus golovatchi n. sp. occurs in caves and in forest litter in far southern Tasmania, and the adults have paramedian and median tergal projections. Asphalidesmus Silvestri, 1910 is removed from Polydesmidea, Haplodesmidae and placed in Dalodesmidea without family assignment.
Improving Psychiatric Hospital Care for Pediatric Patients with Autism Spectrum Disorders and Intellectual Disabilities
Robin L. Gabriels,John A. Agnew,Carol Beresford,Mary Ann Morrow,Gary Mesibov,Marianne Wamboldt
Autism Research and Treatment , 2012, DOI: 10.1155/2012/685053
Abstract: Pediatric patients with autism spectrum disorders (ASD) and/or intellectual disabilities (ID) are at greater risk for psychiatric hospitalization compared to children with other disorders. However, general psychiatric hospital environments are not adapted for the unique learning styles, needs, and abilities of this population, and there are few specialized hospital-based psychiatric care programs in the United States. This paper compares patient outcomes from a specialized psychiatric hospital program developed for pediatric patients with an ASD and/or ID to prior outcomes of this patient population in a general psychiatric program at a children’s hospital. Record review data indicate improved outcomes for patients in the specialized program of reduced recidivism rates (12% versus 33%) and decreased average lengths of inpatient stay (as short as 26 days versus 45 days). Available data from a subset of patients ( ) in the specialized program showed a decrease in irritability and hyperactivity behaviors from admission to discharge and that 35 previously undetected ASD diagnoses were made. Results from this preliminary study support specialized psychiatric care practices with this population to positively impact their health care outcomes. 1. Introduction There is a growing need to establish and evaluate innovative specialized psychiatric healthcare programs for psychiatric patients diagnosed with an autism spectrum disorder (ASD) and/or an intellectual disability (ID). This population is at risk for psychiatric hospitalization due to the fact that psychiatric disorders are highly prevalent in individuals with an ID [1–3]. In addition, psychiatric comorbidities have been reported to be as high as 72% in a pediatric population of individuals with an ASD [4] with increased rates of psychopathology in children and adolescents who are diagnosed with both an ASD and an ID [5–7]. Specifically, there are high rates of affective (depression) and anxiety disorders in the ASD population [4, 7–10]. Factors that may put children with an ASD at higher risk for psychiatric hospitalization include living in a single-parent home, being diagnosed at an older age, engaging in self-injurious and aggressive behaviors, and being diagnosed with depression or obsessive compulsive disorder [11]. This information, combined with the rising ASD prevalence rates [12–14], suggests a growing need for psychiatric preventative and crisis care management options for the ASD population at all ages. An added complication is the fact that the ASD/ID population often lacks the social
