Campodea (Campodea) zuluetai Silvestri, 1932: 128 , fig. VI.

Diagnosis ( Silvestri 1932a; Condé & Mathieu 1957)

Body length 2.5–5.0 mm; epicuticle without microdenticles; long, smooth clothing setae; antennae with 20–29 antennomeres; sensillum of third antennomere in dorsal or ventral position; long, barbed notal macrosetae with barbs along the distal two-thirds distal; marginal setae with long apical barbs; 1+1 ma macrosetae on I–VII urotergites with very variable length (all ma macrosetae short or slightly longer form the anterior urotergites to the posterior ones, the short ma macrosetae less barbed than longer

ones); 1+1 la, 1+1 lp on V–VII urotergites; 1+1 mp, 3+3 lp on VIII urotergite and 1+1 mp, 5+5 lp on IX abdominal segment; cerci covered in long macrosetae almost from basis and a few clothing setae.

Specimens from populations inhabiting cave habitats have antennae with 30–41 antennomeres, and moreover six to eight complex olfactory chemoreceptors inside the cupuliform organ ( Condé 1951b; Sendra & Moreno 2004). Other specimens from different populations collected at several localities in the southeast of the Iberian Peninsula show the la macrosetae on V–VII urotergites in a backward insertion, almost medial posterior position ( Sendra 1989b, Sendra & Moreno 2004). Two types of spermatozoid fascicles in two different populations of C. zuluetai have been described: the specimens from Ariège ( France) with 24–29 antennomeres, sensillum of third antennomere in ventral position and ma urotergal macrosetae reaching the basis of marginal setae from the IV urotergite, and the specimens from the southeast of the Iberian Peninsula with la macrosetae of urotergites in backward position. Both have similar spermatozoid fascicles: small spermatozoid fascicles with 30–40 μm in diameter and 3 μm thick, spiral filament with 1½ to 2 spirals, 200–250 μm long and round shaped with 1 μm in widest section ( Bareth 2006; Sendra 1988). It is clear to conclude that such a high degree of variability in different populations in C. zuluetai will need to be throroughly reviewed.

Habitat and distribution

Inhabits soil and cave environments. It has been collected in caves and found under scree slopes (MSS) in Ariège, Pyrenées ( Bareth 1983) and Guadarrama National Park ( Sendra et al. 2017a). Some specimens collected in caves show hyperthrophy of the cave-adapted traits. It was also found at high-altitude, 2785 m a.s.l. in the Cangou peak, Pyrenees ( Condé & Mathieu 1957). It is distributed in a large area in the eastern Iberian Peninsula, from the French Pyrenees to the Baetic Mountains, including the Central System Massif ( Condé 1951b; Condé & Mathieu 1957; Sendra & Moreno 2004). It was also found in two caves in Menorca, and in Sardinia where it seems to be abundant in the soil ( Bareth 1980).
