The epithet conicornis derives from recognition of the cone-shaped (coni-) thoracic horn (- cornis) of the pupa. This remains a discriminatory feature. Remarks. Adult males of C. conicornis can be distinguished by the combination of uniformly dark legs and abdomen and posteriorly projecting inferior volsella. Females also have uniformly dark legs and abdomen, and elongated spermathecal capsules. Pupae can be recognised by the large, apically scaly, yellow-brown thoracic horn and reticulate pattern on abdomen. Larvae can be recognised by the first lateral mental teeth being level with the median tooth, and the relatively short apical mandibular tooth relative to the large first inner tooth. This species is similar in colour pattern to that described by Hergstrom (1974) for C. phaeosomatus. However C. conicornis differs in having the adult male AR much less than the 1.8 of Hergstrom (confirmed on Hergstrom's proposed holotype as 1.9). The distribution of C. conicornis encompasses the tropical and subtropical parts of the continent, but includes some sites in alpine south-east Australia and Tasmania. The species preference seems for clean creeks and moderately healthy rivers.Published as part of Drayson, Nick, Cranston, Peter S. & Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.

Mentum 112–148 µm, mid-brown; 6 pairs laterals, 2 nd slightly reduced. Abdomen. Pc 22–27 µm, A.s. 500–530 µm. Etymology. The epithet ‘ tasmania’, a noun in apposition, derives from its original collections suggesting endemism to Tasmania. We retain the name although there is molecular evidence showing the species presence in high elevation alpine and sub-alpine streams in south-eastern mainland Australia. Remarks. Adults of C. tasmania can be distinguished by their uniformly pale legs, pattern of pale tergites and in the male the A.R. is unusually low. Pupae can be recognised by the presence of spine/spinule fields on TII and by the usual presence of 5 long L setae on VIII. Specimens from mainland Australia seemingly can lack the distinctive 5 th L seta on VIII, but whether this is damage or true absence is unclear. Larvae can be recognised by the mandible having a smooth outer margin, serrate inner margin, and being narrow above the mola. The validity of the colour contrasts used in the key need verification. The adult of this species resembles in colour and pattern C. phaeosomatus described by Hergstrom (1974), but differs in having the A.R. of adult males much less than the value of 1.9 (as inverse 0.53 of Hergstrom, and confirmed by Cranston). Molecular data suggest monophyletic non-Tasmanian specimens are embedded in a diversity of Tasmanian sampled specimens (Krosch et al., submitted). C. tasmania inhabits clean cool streams often at elevation, in south-east Australia including Tasmania where it appears widespread.Published as part of Drayson, Nick, Cranston, Peter S. & Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.

They can be distinguished from <i>C. varicornis</i>, for which the leg pattern is not known, only by the pattern of tergal setation, and the spermathecal capsule shape, both of which features may be unreliable. Pupae are easily recognised by the dark adhesion marks on all abdominal segments. The frontal setae are present on the prefrons, tergites I and II essentially bare of spines or spinules, and mid-paraterga spinulose. From the otherwise similar <i>C. howensis</i>, it can be distinguished by the thoracic horn bearing apical/subapical small tubercles (Fig. 6 E). Larvae can be recognised by the mandible having a moderately elongate apical tooth, crenulate outer and smooth inner margin, antennal blade reaching apex of antenna with large Lauterborn organs, and especially, but not always, the presence of a small 7th lateral tooth on the mentum.</p> <p> As discussed below, Hergstrom (1974) included specimens of <i>C. hillmani</i> in her <i>" C. parbicinctus</i> ". A specimen in the A.N.I.C. collection was identified by Freeman as C. <i>annuliventris,</i> but the thorax, legs and abdomen clearly show it to belongs to <i>C. hillmani.</i></p> <p> <i>C. hillmani</i> is an essentially south-eastern Australian species (including Tasmania) with an anomalous record from far north Queensland. Records are all from rivers and creeks in good water health.</p>Published as part of <i>Drayson, Nick, Cranston, Peter S. & Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.

The epithet refers to the pupa lacking (a-) a thoracic horn (-cornis). Remarks. Adult males of C. acornis sp. n. can be recognised by the combination of uniformly dark abdomen and legs and notched inferior volsella: females can be recognised by uniformly dark tergites and legs and near spherical spermathecal capsules. Pupae lack thoracic horns but otherwise resemble C. parbicinctus in lacking frontal setae, and having non-spinose TI and II. Differentiation can be made based on the presence of small patches of spines/spinules postero-lateral on tergites VI–VI in C. acornis. Note that some pupae of any species can ‘lose’ their thoracic horns during drift post-emergence or in subsequent handling, even in slide preparation, and identity as C. acornis should not be assumed. Larvae can be recognised by the mandible with a crenulate outer margin, smooth inner margin and being wide above the mola. C. acornis sp. n. was collected first from an ephemeral stream that had ceased flow on a subsequent visit. Other records are scarce, from mid-order creeks and rivers in a restricted area of south-eastern Australia. No material for molecular study was collected.Published as part of Drayson, Nick, Cranston, Peter S. & Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.

This is no longer a discriminatory feature but the name is retained.</p> <p> <b>Remarks.</b> Adults of <i>C. brevicornis</i> <b>sp.n.</b> can be recognised by the unique colour pattern of the abdomen (Fig. 1 D). Pupae have frontal setae on the prefrons, weak pattern on TII, no paratergal spinules, and stout D4 seta on TIII. Larvae can be recognised by the mandible uniquely amongst Australian <i>Cricotopus</i> being smooth on both inner and outer margins, and with small Lauterborn organs and 2nd antennal segment subequal to combined 3rd and 4th segments. These features however are shared with larvae of two or more Australian members of the genus <i>Paratrichocladius</i>. From ‘M1/FNQ1’ <i>brevicornis</i> is separated by the normal-length apical mandibular tooth, but separation from a taxon <i>Paratrichocladius</i> ‘SW QLD’ is very difficult, and features used in the key may not hold up (see Comments below).</p> <p> <i>C. brevicornis</i> is widespread in warmer parts of Australia, absent from Tasmania and present in Victoria only in the north-east on the Murray River. The species tolerates elevated temperatures and nutrient levels, in both larger rivers and creeks.</p>Published as part of <i>Drayson, Nick, Cranston, Peter S. & Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.

Health Hazard Evaluation Report: HETA-89-035-1999: Cranston General Hospital (Osteopathic); Cranston, Rhode Island
No full textIn response to a request from the Assistant Administrator of the Cranston General Hospital (SIC-8062), Cranston, Rhode Island, an investigation was made of possible hazardous working conditions due to exposure to nitrous-oxide (10024972). The hospital has three active operating rooms with as many as nine employees potentially exposed to the gas at any one time. Operating room personnel complained of headaches and tiredness. The company supplying the anesthetic equipment conducted an on-site evaluation of the equipment and indicated leaks were detected at the absorber. A recommendation was made that all rubber hose connections be changed. Air quality measurements were then taken by the hospital insurance company and found to be in excess of the NIOSH recommended limit of 25 parts per million (ppm). Corrective action was then taken by the management of the hospital. Five area samples collected subsequently by NIOSH during three different surgical procedures indicated nitrous-oxide levels of less than or equal to 10ppm. The author concludes that a health hazard did not exist from exposure to waste anesthetic gases. The author recommends that the hospital's existing program for controlling exposure to waste anesthetic gas and vapor be strengthened

Cosmophasis waeri Hurni-Cranston & Hill 2021, new species
No full text12. Cosmophasis waeri, new species Figures 51-52, Map (Figures 1-2) #60 Type material. The holotype ♀ (HC-BB5 f) was collected by the senior author on a small potted Codiaeum variegatum plant at Waer, on the eastern side of Banda Besar (Banda Island), in the Banda Islands (collected 8 FEB 2016, specimen preserved in alcohol 18 FEB 2016). This specimen will be deposited in the Florida State Collection of Arthropods (FSCA), Gainesville. Etymology. The species name, waeri is a reference to the fact that this species was found at Waer on Banda Besar. Diagnosis. The female C. waeri most closely resembles C. squamata, also found on Banda Besar. However the epigynum is completely convex, lacking the two parallel furrows characteristic of C. squamata. In addition, a small orange spot is present at the center of each darker area on the dorsal opisthosoma of C. waeri. Below each light-yellow or off-white marginal band on either side of the opisthosoma, there is only a narrow and irregular dark brown line in the female C. waeri. This dark line is much wider in C. squamata. The carapace of our specimen appears to be rubbed in the eye region, but there is no sign of the pair of dark transverse bands that cross the carapace of C. squamata. The male is not known. Description of female (Figures 51-52). Length about 5 mm (Figure 52:1-2). Chelicerae typical for genus, dark amber in colour, mostly glabrous. A single large, unidentate, triangular tooth is present, toward the median, on both the anterior and posterior margins of each fang groove (Figure 52: 3-4). White scales surround the anterior eyes below, orange scales above. Scale cover of eye region not known. Narrow white band present around the margin of the carapace, a shorter narrow band just above this near the front. Carapace dark brown, with dense cover of iridescent green-gold scales around the sides and to the rear of the PLE. Dorsal opisthosoma covered with dense array of dark brown, rounded, overlapping scales, with a wide marginal band of light-yellow or off-white, rounded, overlapping scales extending from the front around most of the length of each side. Below this on either side a narrow, interrupted, brown line is present. Three transverse bands of these scales cross the dorsal opisthosoma, where a less regular and interrupted median tract of the same scales is also present. A small orange spot is present at the center of each dark-brown area. At the rear of the dorsal opisthosoma, and on the dorsal surfaces of the posterior lateral spinnerets, iridescent violet scales are present. Below, the opisthosoma is light yellow-brown, with two pairs of large white spots on either side, and a dark then light transverse band at the rear (Figure 52:2). The spinnerets are grey and unremarkable. Legs as shown in Figure 50, with some iridescence and indistinct longitudinal stripes. The epigynum (Figure 52:5-9) is convex and triangular, similar in outline to that of C. squamata but otherwise distinctive. Figure 52:9 (and to a lesser degree, Figure 52:5) best illustrates the pair of convex, diagonal lobes on either side of the septum, each behind a longer but narrower transverse lobe.Published as part of Hurni-Cranston, Tiziano & Hill, David E., 2021, Three new jumping spiders of the genus Cosmophasis from Wallacea (Araneae: Salticidae: Chrysillini), pp. 1-84 in Peckhamia 228 (1) on page 58, DOI: 10.5281/zenodo.717190
