Cathormiocerus inflatiscapus Escalera, 1918

Material examined. 1 ♂, Flood pool by Burgos-Valladolid, Rd 24 km from Burgos, 16.v.74, R. B. Argus lgt. (BMNH); 14 ♂♂ and ♀♀, Spain, Puerto El Collado, Sierra de la Demanda, H. Franz lgt. (NHMW).

Remarks. This species was known only from two females from the type locality Sierra de las Canales (Spain, Logroño), to which three species are closely related: the bisexual C. longithorax Borovec & Bahr, 2006, and the assumed parthenogenetic C. cylindrus Borovec & Bahr, 2006 and C. sinuatiscapus Pic, 1915. All four species are known exclusively from the Iberian peninsula. The two sexes of C. inflatiscapus are easy to distinguish because of the different shape of the antennae which in males are much slenderer than in females (Figs 20, 21). Although the antennae, primarily the funicles, are extremely robust, males have a slenderer scape, funicle segment one 1.6–1.7 times as long as wide; segment two 1.5–1.6 times as long as wide; segments three to six 1.1–1.2 times as wide as long and segment seven 1.3–1.4 times as wide as long, whereas females have segment one 1.1 times as long as wide; segment two isodiametric; segments three to five 1.7 times as wide as long; segment six 1.6 times as wide as long and segment seven 1.5 times as wide as long. The penis is illustrated here for the first time (Figs 30, 31).
