- SST (± 0.05 deg C): SST was measured with a thermosalinograph from Seabird (SBE37) which was installed in the ships moonpool next to the inlet pump at approximately 6 m depth.
-Equilibrator temp (±0.05 °C): Due to a broken temperature probe, we used the temperature of an Aanderaa Optode that was placed in a continously flushed water bath next to the equilibrator. We still estimate the accuracy of teh equilibrator to 0.05 deg C.
-SSS (± 0.1 PSU): SSS was measured with a thermosalinograph from Seabird (SBE37) which was installed in the ships moonpool next to the inlet pump at approximately 6 m depth.
-Atmospheric press. (± 0.1 mbar): The atm. pressure was measured by the ships weather station.
-Equilibrator press (± 0.1 mbar): The equilibrator is open to the atmosphere. Here we assume to have atmospheric pressure in teh equilibration chamber.

A Weiss equilibrator was used for teh equilibration. The sample gas stream was firts dried by cooling and then with a Nafion dryer. The gas was first led to the LI-6252 for the pCO2 measurements and then through a LGR N2O analyser. The system is described in detail in Arevalo et al. (2012) and the whole setup is described in Steinhoff (2010). Surface water is pumped continuously (by a torque flow pump) from the intake to the equilibrator. The equilibrator contains a water spray head, and as the water flows through it the dissolved CO2 equilibrates with the headspace. The headspace is dried and xCO2 is determined by an infrared sensor. Calculations were performed following Pierrot (2009) and are described in detail in Steinhoff (2010). The atmospheric xCO2 values are very noisy and are reported as is

Synthorax (Figs 4d, 5d): mesepisternum black, with a large oval pale blue antehumeral shield, the inner edge of which is somewhat irregular and the outer edge of which follows the mesopleural suture. Extent of this blue shield is about two-thirds of the width, and three-fifths of length of mesepisternum. Mesepimeron and mesinfraepisternum black. Metepisternum black with large rectangular pale blue area, which forward reaches proximity of mesocoxa. This blue area with a small rounded excision along its upper margin near the wing base, and with black margin along wing base connecting the black of mesepimeron to the well-defined black line over metapleural suture. Metepimeron bluish white with brown, irregular smudge near coxae, metinfraepisternum black. Legs: coxae and trochanters white. Femur grayish with black stripes.

Within this group it shares the combination of large blue antehumeral shields, bold black lines over mesopleural and metapleural sutures and yellow abdominal tip with <i>C. uenoi</i> (Fig. 25 e–f, 29a–b) and <i>C. phamiha</i>. In <i>C. phamiha</i> the flagella of the genital ligula are directed laterally and posteriorly, before curving inward apically (Phan & Tran 2018), whereas in <i>C. uenoi</i> they are robust and directed first laterally and then anteriorly (Fig. 13). In <i>C. curua</i> the flagella are curved posteriorly, hidden in ventral view under terminal segment, but apical third directed laterally and visible in ventral view (although limited so or not at all in Xuan Son specimens) (Fig. 12). The antehumeral shields of <i>C. uenoi</i> have a characteristic step on the inner margin and are not oval (Figs 25 e–f, 29a–b), and the black lines over the metapleural and mesopleural sutures are narrower. <i>Coeliccia phamiha</i> has even larger antehumeral shields that obviously and suddenly narrow at their center, and has black S9–10, besides structurally different and whitish cerci (Phan & Tran 2018). The caudal appendages of <i>C. curua</i> and <i>C. uenoi</i> are similar in structure (Figs 9, 10).</p> <p> <b>Habitat and ecology.</b> In Ba Be NP <i>Coeliccia curua</i> <b>sp. nov.</b> was found at two different locations in karst mountains with seeps over rocks and forest floor, where it occurred with <i>C. pyriformis</i> and <i>Protosticta nigra</i> Kompier, 2016. In Xuan Son NP it was found at two small and very shallow streams at appr. 900m asl. in degraded primary forest, similarly on karst mountains. Xuan Son NP boasts at least 7 other <i>Coeliccia</i> species, including the similar <i>C. uenoi,</i> but only <i>C. pyriformis</i> was found together with <i>C. curua</i>.</p>Published as part of <i>Kompier, Tom, Dow, Rory A. & Steinhoff, Philip O.

Anal appendages (Fig. 22f). Cerci blackish brown, half as long as S10, ovipositor blackish brown, extending almost the length of S10 beyond cerci. Measurements (in mm). HW 26; abdomen incl. appendages 37. Differential diagnosis. The structure of the genital ligula, with apico-lateral flagella and apical flap (Fig. 11 gh), places Coeliccia caerulea in the pyriformis -group. It differs clearly in coloration from C. curua, C. uenoi and C. phamiha, which have large blue antehumeral shields, and in the case of C. curua and C. uenoi yellow S9–10. The coloration of its thorax (Figs 4a, 5a, 26 a–b) is more similar to C. mientrung and C. pyriformis. The slightly curved blue antehumeral stripes are similar to those of the generally larger C. pyriformis, whereas in C. mientrung they are clearly shorter (Kompier & Phan 2017). Both these species have yellow S9–10 and C. pyriformis also has bicolored compound eyes in life, lacking green. Its yellow cerci have the ventral expansion placed slightly further distally than in C. caerulea, where it is placed one-fourth of cerci length back from the apex. The genital ligula of C. pyriformis has flagella with hammerhead shaped apices. The male of C. mientrung has similar genital ligula as C. caerulea, but the ventral expansion of its cerci is placed even further distally than in C. pyriformis. Coeliccia mientrung also has larger white spots laterally on the middle pronotal lobe of the prothorax. Coeliccia cyanomelas has blue abdominal tip, different thoracic pattern and shape of the cerci (Yu et al. 2019). The female of C. caerulea shares the general structure of the prothorax with the females of C. pyriformis, C. phamiha and C. mientrung. The posterior pronotal lobe has a rounded central part (Fig. 21d), which is similarly rounded or more triangular in C. mientrung and C. phamiha, but squarish in C. pyriformis. Unlike in these species, S9 is completely dark, without a prominent yellow dorsal spot (Fig. 22f). In C. mientrung the labrum is largely yellow, whereas in C. pyriformis the yellow from the genae generally does not continue as far over the antefrons above the postclypeus. The yellow spot laterally on the middle pronotal lobe of the prothorax is much reduced compared to both C. mientrung and C. pyriformis, which are largely yellow laterally, whereas in C. phamiha the middle pronotal lobe appears to be completely yellow. Coeliccia uenoi differs for instance by the shape of the extension of the posterior pronotal lobe, with has raised lateral corners (Asahina 1997) and the largely yellow middle pronotal lobes. Coeliccia cyanomelas has no central extension of note on the posterior pronotal lobe of the prothorax. Habitat and ecology. Coeliccia caerulea sp. nov. was found in degraded primary forest along a rocky and fast flowing mountain stream, along which C. coronata sp. nov., C. poungyi dasha Kosterin, 2016, and C. rolandorum also occurred.Published as part of Kompier, Tom, Dow, Rory A. & Steinhoff, Philip O.

Trigeminal evoked potentials and sensory deficits in atypical facial pain - a comparison with results in trigeminal neuralgia
No full textTrigeminal evoked potentials (TEPs) and sensory deficits in eighty-three patients admitted for first surgical treatment of facial pain were retrospectively analysed. Thirty-seven patients suffered from trigeminal neuralgia (TN), 10 from symptomatic TN (sTN), and 36 from atypical facial pain (AFP). Eighteen percent of the TN patients reported sensory deficits on the pain side, but 35% had delayed ipsilateral N13 waves. Of the sTN patients, 60% had either sensory deficits or a pathological corneal reflex and 62.5% a pathological N13. Of the AFP patients, 61% complained of sensory deficits, but only 31% had a pathological N13. The percentage of pathological P19 waves was slightly lower (20%, 50%, and 11%, respectively), but showed a similar trend. Normal TEPs were found even in the presence of a sensory deficit (reported only in the AFP group). These findings may add weight to the hypothesis of underlying psychiatric disorders in AFP
