Urosternite I with up to 30 macrochaetae (hypertrichia); urosternites II to VII with 5+5 and VIII with 2+2 macrochaetae. Urosternite I of male without glandular g1- setae; subcylindrical appendages with glandular a1 -setae and a2 -setae; female with glandular a1 -setae. Cerci longer than the body, but less than twice as long.
Description. Lengths of body 3.9 to 5.6 mm (males), 3.6‒7.0 mm (females). Cercal length in adults 4.4 to 7.0 mm (n = 4), cercal and body lengths approximately correlated. Epicuticle without ornamentation; clothing setae sparse, glabrous or with short distal barbs.
Antennae with 34 to 41 antennomeres: 34, 35, 36 (1 antenna each); 37 (3 antennae); 38 (7 antennae); 39 (2 antennae); 40, 41 (1 antenna each); regenerated antennae with 28, 31 and 33 antennomeres. Sensillum of third antennomere subcylindrical, short, located ventral between macrochaetae d and e. Central antennomeres 2.5× longer than wide. Apical antennomere about 2.3× longer than wide, its cupuliform organ occupying one-sixth of the length, containing 8 to 10 sensilla with 2 or 3 collarettes, each with a reticulated surface (Fig. 2 B). Sensilla well developed, in cross-section concave-convex (Fig. 2 A); one sensillum on the third antennomere, increasing gradually to about 6 sensilla in the medial antennomeres, to 10 sensilla in the distal antennomeres; on each antennomere the sensilla arranged in distal verticils. Frontal process not developed, with an barbed apical macrochaeta along the distal four-fifths and with several setae with a few barbs. Three macrochaetae along the line of insertion of the antennae and x setae with the following relative lengths: a = 0.53, p = 0.64, i = 0.79, x = 1. Labial palp suboval, with subcylindrical lateral-external sensilla similar to sensilla of maxillary palp and third antennomere, two guard setae, up to 11 setae on the anterior border and 150 neuroglandular setae.
Thoracic nota elongated. Distribution of macrochaetae: pronotum with 1+1 ma, 3+3 la1,2,3, 2+2 lp2,3 (Fig. 3A); mesonotum with 1+1 ma, 3+3 la1,2,3 (3+2 on a female of 7 mm), 2+2 lp2,3 and 1+1 mp; metanotum with 1+1 ma, 2+2 la1,2, 2+2 lp2,3, 1+1 mp. All macrochaetae thin and short with thin barbs along distal two-thirds. Pronotum with 1+1 well developed setae near center of the notum, la 1 and la 2 less differentiated than the other macrochaetae. Marginal setae thin, barbed along their distal half to two-thirds. Elongated legs, length of metathoracic leg reaching or exceeding abdominal segment X. Femur III with long dorsal macrochaeta with thin barbs except basally, inserted near middle of femur. Ventral femoral macrochaeta shorter and more distal than the dorsal macrochaetae. Usually two well-barbed ventral macrochaetae on tibiae I to III; in a few specimens tibia III with 3 or 4 ventral macrochaetae. All tarsal setae barbed, dorsal setae (sda, sdp) and the 3 lateral setae (sla) barbed in the middle, distal and proximal portions glabrous (Fig. 2 C, D), subapical ventral setae thinner than the others and completely barbed. Subequal claws with ridged lateral crests, without elongated talon. Telotarsal process laminar with dense sternal barbs (Fig. 2 C, D).

Urosternite I (Fig. 3B) with up to 30 macrochaetae (hypertrichia); urosternites II to VII with 5+5 macrochaetae, urosternite VIII with 2+2 macrochaetae. Apical setae of styli with basal tooth and 10 to15 distal barbs; subapical and medial sternal setae completely covered with thin barbs. Each cercus with a base divided into 2 or 3 secondary articles, followed by 8 or 12 primary articles.
Male urosternite I without glandular setae on posterior margin (Fig. 3B). Subcylindrical appendages of urosternite I bearing 8 to10 glandular a1 -setae on their apex and a lateral-internal field of 16 to 88 longer, thinner glandular a2 -setae. Spiral of spermatozoid bundles 70 to 90 µm long with one and one-half turns; wider section 4.5 µm. Spiral filament broadly rounded on one end and pointed at other end; pointed end divided or entire (Fig. 3C, D).
Female subcylindrical appendages on the urosternite I similar to those of male but narrower, shorter (12 to 20 µm) and with more glandular a1 -setae (30‒40).

Etymology. This species is named for the Iberian Peninsula, where this species is distributed along the Iberian and Prebetic Mountains..
Geographic distribution. Caves located in the large karstic area occurring along the Castilian-Valencian Branch of the Iberian Mountain Range, which extends to the northwestern Prebetic Mountains and is bordered by Tertiary and Quaternary basins.
Affinities. Cestocampa iberica n. sp. closely resembles C. gasparoi and C. balcanica. The three species share the presence of mp macrochaetae on the meso- and metanotum and the chaetotaxy of the notal and urotergal macrochaetae. In addition, C. gasparoi and C. italica lack a glandular field on the posterior border of urosternite I, but show a lateral-internal glandular setae field on the appendages of the males. Cestocampa iberica n. sp. differs from C. gasparoi by the number of hypertrichia on urosternite I (up to 30 macrochaetae vs. 7+7 or 7+1+ 7 in C. gasparoi) and the number of macrochaetae on urotergites VIII and IX i (7+7, 9+9, vs. 6+6, 8+ 8 in C. gasparoi and C. balcanica; character unknown in C. italica). Further differences are closely related to the more progressive troglomorphy (sensu Christiansen, 2005) of C. iberica n. sp. (longer appendages and increased number of antennomeres and cercal articles, and complexity and high number of sensilla in the cupuliform organ).
