Etymology. The new species is dedicated to the Bullón family, owners of the Cueva de la Pileta de Benaoján, Málaga, the type locality.

Description. Maximum size male 3.4 mm, female 3.6 mm. Body unpigmented. Eyes absent. Body ovoid; outline slightly stepped between pereon and pleon ( Figs 2A View FIGURE 2 , 6 View FIGURE 6 A–C, 7). Pereon tergites ( Fig. 2B View FIGURE 2 ) very convex, with fine honeycomb basal structure ( Fig. 6D View FIGURE 6 ). First pereon epimera directed obliquely forward; 2–4 expanded towards outside, 5–7 directed obliquely backwards. Cephalon ( Figs 2C View FIGURE 2 , 6B View FIGURE 6 ) with triangular frontal lobe, with rounded tip raised upwards; lateral lobes rounded, directed obliquely forward; central tubercle large, subconical, divided into 2 lobes and with 2 other accessories subapical; central posterior tubercle smaller, bilobate; two less prominent lateral protuberances; two small prominences between front and central lobe. Pereonites 1–6 ( Fig. 2B View FIGURE 2 ) with four raised tubercles (2+2); central tubercles larger than external ones; two rugosities on each side. Pereonite 7 ( Figs 2B View FIGURE 2 , 6C View FIGURE 6 ) with 2 large, closely, central tubercles, separated basally, and 2 lateral accessory rugosities. Pleonites 3–5 ( Fig. 6C View FIGURE 6 ) smooth, with moderately developed epimera distally rounded and directed backwards. Telson trapezoidal, with slightly concave hind margin. First antenna ( Fig. 2D View FIGURE 2 ) tri-articulated; basal article, largest; articles 2–3, subequal; distal article with 3 aesthetascs. Second antenna ( Fig. 2E, F View FIGURE 2 ): flagellum indistinctly tri-articulated with groups of 2–3 aesthetascs in articles 2 and 3. Right mandible ( Fig. 3D View FIGURE 3 ) with 1 free penicil near lacinia mobilis; left mandible ( Fig. 3E View FIGURE 3 ) with 2 free penicils. Maxillula ( Fig. 3A View FIGURE 3 ): outer branch with 5+5 teeth and slender seta; internal branch with 3 penicils and hairy distal lobe; smallest penicil inserted laterodistally. Maxilla ( Fig. 3C View FIGURE 3 ) with bilobed distal part; internal lobe with 14–15 sensillae; external lobe with 3–4 sensillae and fine hairs; internal lobe approximately twice as wide as external one. Maxilliped ( Fig. 3B View FIGURE 3 ): endite with 1 thick subconical penicil and strong subapical seta; basal article of palp with 2 setae and rounded distal part with numerous sensillae forming 3 groups. Pereopods ( Figs 4A, B View FIGURE 4 , 5A, B View FIGURE 5 ): see male sexual characteristics. Uropod sympodites dorsoventrally flattened, reaching pleotelson hind margin; endopod shorter than exopod.

Male. Pereopod 1 ( Fig. 4A, B View FIGURE 4 ) without modifications. Pereopod 7 ( Fig. 5A, B View FIGURE 5 ) not modified. Pleopod 1 ( Fig. 4C View FIGURE 4 ): exopodite subtriangular with posterior lobe rounded distally, shorter than basal part; tip reaching half of endopod length; thick endopod, with subconical tip asymmetrically striated. Pleopod 2 ( Fig. 4D View FIGURE 4 ): exopod with concave outer margin; internal margin convex, with rounded posterior tip reaching one third of endopod length; endopod with thin distal seta. Genital papilla ( Fig. 4E View FIGURE 4 ) distally setose.
