Etymology

This species is named after Milan Ferran, an enthusiastic caver, discoverer and explorer of the type locality in Ferranova buža (meaning Ferran’s hole), Slovenia.

Material examined

Holotype

Paratype

SLOVENIA • 1 juv.; same collecting data as for holotype; Coll . AS.

Description

BODY. Body length 3.0 mm (holotype) and 2.8 mm (paratype). Epicuticle smooth under optical microscope; body with sparse middle-sized clothing setae, distal two-thirds with thin barbs.

HEAD. Two intact antennae in holotype, slightly longer than body length (3.5/ 3.6 mm), with 32/33 antennomeres, in paratype slightly shorter than body length (2.76/ 2.75 mm), with 32/32 antennomeres. Small, subcylindrical sensillum of third antennomere in ventral position between c and d macrosetae; central antennomeres 1.7× as long as wide, apical antennomere 2.0× as long as wide; cupuliform organ occupies of its length, with 7 or 8 spheroidal olfactory chemoreceptors, each with at least two folds, in cupuliform ⅙ organ; gouge sensilla starting on ventral side of third antennomere, with an apical row of eight gouge sensilla; fourth antennomere with 12 ventral gouge sensilla and 1 dorsal gouge sensillum; fifth antennomere with 12 ventral and 2 dorsal gouge sensilla; sixth antennomere with 13 ventral and 4 dorsal gouge sensilla; seventh antennomere with 15 ventral and 6 dorsal gouge sensilla; eighth antennomere with 14 ventral and 7 dorsal gouge sensilla; ninth antennomere with 12 ventral and 8 dorsal gouge sensilla; after tenth antennomere a complete apical whorl of gouge sensilla on each antennomere, with about 20 on medial antennomeres and 15 on distal ones. Frontal process with nontubercular macrosetae or setae; macrosetae along line of insertion of antennomere and x setae similar in length, with long, thin distal barbs, on distal two-thirds (a/i/p/x with relative lengths of 33/30/26/ 39 in holotype). Small suboval labial palps with a long subcylindrical sensillum, two guard setae, four normal setae and up to 72 neuroglandular setae.

THORAX. Pronotum with 1+1 ma, 2+2 la 2,3, 2+2 lp macrosetae; mesonotum with 1+1 ma, 2+2 la 2,3, 2+2 lp 1,3 macrosetae; metanotum with 1+1 ma, 1+1 la, 2+2 lp 2,3 macrosetae; long notal macrosetae, barbed along distal four-fifths; long marginal setae with barbs along distal two-thirds ( Fig. 193 ). Legs elongated (1.84 mm long in holotype and 1.54 mm in paratype), overpassing end of abdomen. Femur with one long dorsal macroseta, barbed almost from its base, inserted around middle of article. No ventral tibial macrosetae. Calcars with 2–3 rows of long barbs from base, with a smooth and narrow lateral side along each calcar. Dorsal and lateral subapical tarsal macrosetae smooth. Very unequal claws, posterior claw 1.6–1.8× as long as anterior one, including a large backward overhang on posterior claw; ventral surface of claws with grooves, dorsal surface including large lateral crests with thin stripes. Setiform pretarsal processes reaching extremities of claws ( Fig. 194 ).

ABDOMEN. Distribution of abdominal macrosetae on tergites: 1+1 (holotype) or 0+0 (paratype) la, 2+3 post 3,4,5 on urotergite VII; 5+5 post on urotergite VIII; 7+7 post on abdominal segment IX. All post urotergal macrosetae long, robust, barbed on distal four-fifths; la urotergal macrosetae much shorter, barbed along distal half ( Fig. 195 ). Urosternite I with 6+6, urosternites II–VII with 5+5, urosternite VIII with 2+2 macrosetae; all urosternal macrosetae robust, covered by very long barbs along distal half to three-fourths. Pseudoarticulated stylus with barbed setae with long barbs, apical setae shorter than medial and subapical setae.

SECONDARY SEX CHARACTERS. Male urosternite I without glandular g 1 setae, subcylindrical short, enlarged appendages with up to 21 large glandular a 1 setae. Adult female unknown.

Phyletic affinities, habitat and distribution

Plusiocampa (V.) ferrani sp. nov. is the second representative of the subgenus Venetocampa . It is a cavedwelling species closely related to P. (V.) paoletii , found in the vinicity of Belluno, Italian Alps ( Bareth & Condé 1984). Nonetheless, the macrosetal distribution patterns on the nota and urotergites show enough differences to describe these specimens as a new taxon.
