Campodea (Dicampa) catalana Denis, 1930: 28, figs 7–13.

Diagnosis (Denis 1930; Condé & Mathieu 1957; Sendra & Jiménez 1983; Sendra & Moreno 2006)

Body length 2.5–4.0 mm; epicuticle with microdenticles; short, smooth clothing setae; antennae with 18–26 antennomeres, with up to 31 in populations inhabiting shallow subsurface habitats, such as the MSS (Sendra et al. 2017a); sensillum of third antennomere in dorsal position, smaller and in ventral position in several populations in the northeast of the Iberian Peninsula; cupuliform organ with four simple olfactory chemoreceptors but increasing in number in specimens from MSS habitats; short ma and la notal macrosetae with a few barbs and long lp notal macrosetae with barbs along distal half; marginal setae with long apical barbs; 3+3 lp macrosetae on VIII urotergite, 5+5 lp on IX abdominal segment; cerci shorter than body and covered in long macrosetae with barbs along distal half to twothirds and a few shorter, smooth setae, but in proximal articles with latero-interior macrosetae ending in sharp shape to slightly swollen.

Taxonomic notes

The studied material (Supplementary file 2) has allowed to photograph some structures under SEM (Figs 2–4, 19–22).

Habitat and distribution

Soil-dwelling species inhabiting all layers of the soil, and the MSS on scree slopes (Sendra et al. 2017a), from the sea level to the highest mountains of the Iberian Peninsula under Mediterranean climate (Denis 1930; Condé & Mathieu 1957; Sendra & Jiménez 1983; Sendra & Moreno 2006).
