Figures 158-160 in Review of Grosphus Simon 1880 with description of Teruelius gen n a new buthid genus from Madagascar (Scorpiones Buthidae)

Figures 158-160. Comparative intensity of UV fluorescence in Grosphus and Teruelius gen. n. Figure 158. Horizontal histograms comparing relative fluorescence emission intensities measured by photodiode current, for Grosphus and Teruelius species. Histogram bars are means, error bars are SE, species averages over all samples, male and female (sexes not significantly different, P> 0.05). Sample sizes: G. hirtus, 1♂, 1♀; G. sp. nr hirtus, 6♀; G. madagascariensis, 9♂, 1♀; G. voahangyae, 4♂, 1♀; T. ankarafantsika, 2♂, 2♀; T. ankarana, 1♂, 1♀; T. flavopiceus, 1♂, 1♀; T. grandidieri, 1♂, 1♀; T. limbatus, 6♂, 5♀; T. mahafaliensis, 2♂, 2♀; T. olgae, 1♂, 1♀. Sample means may not reflect single specimen intensities recorded in Figs. 145–157. Figure 159. Time course of photodiode current in UV fluorescence emission measurement for T. limbatus (upper curve), and two specimens of G. madagascariensis (middle and lower curves) over 620 s. Arrow indicates time of shutter opening to initiate UV excitation.160. Photobleaching time course for UV fluorescence emission of T. limbatus (middle curve) and G. madagascariensis (upper and lower curves) over 600 s following shutter opening (see Fig. 159). Ordinate is percentage bleaching relative to initial fluorescence after shutter opening. Blue curves are mono-exponential fits with decay time constants: T. limbatus, 640.2 s; G. madagascariensis, #1 654.4 s and #2 347.5 s.
