Figures 125–134 in New picobuthoid scorpions (Scorpiones: Buthidae) from Oman

Figures 125–134: Picobuthoid trichobothriotaxy. 125. Schematic showing trichobothrial nomenclature for right pedipalp chela (dorsoexternal aspect) of Microbuthus used by Vachon (1952, 1974). 126. Schematic showing revised trichobothrial nomenclature for right pedipalp chela fixed finger (dorsoexternal aspect) of picobuthoids, including Microbuthus, based on homologies with other buthids derived from locations of trichobothria relative to landmark carinae. Trichobothrial sockets visible on dorsal and external surfaces are shown as circles with solid outline, those hidden on internal surfaces as circles with dotted outline. 125–126, with holotype of M. gardneri as example. 127–132, stylized schematics of upper sides of right pedipalp chelae of Microbuthus and representatives of five other buthid genera, comparing placements of fixed finger trichobothria with respect to landmark carinae. Carinal terminology after Soleglad & Sissom (2001), i.e. E = external, D1 = digital, D3 = dorsal secondary, D4 = dorsal marginal, D5 = dorsal internal. Solid lines indicate strong carination, dotted lines weak carination. 127. Microbuthus gardneri, sp. nov., adult female paratype from type locality (Jabal Bani Jabir). 128. Tityus ecuadorensis Kraepelin, 1896, adult male. 129. Isometrus melanodactylus (L. Koch, 1867). 130. Lychas marmoreus (C.L. Koch, 1844). 131. Orthochirus scrobiculosus (Grube, 1873). 132. Androctonus crassicauda (Olivier, 1807). 133–134, fluorescence images of the right pedipalp patella of Microbuthus species from Oman, dorsal aspect, showing positions of dorsal trichobothria, and the tendency for placement of d3 towards external side of dorsomedian carina (for illustrative purposes, fluorescence contrast of trichobothrial sockets was enhanced). 133. Microbuthus gardneri, sp. nov., female paratype (Al Khod). 134. Microbuthus kristensenorum, sp. nov., female paratype (Jabal Qamr). Scale bars in Figs. 129–130: 0.50 mm.
