Etymology. The new species is named after our friend and mentor Dr. Mario García-París, in recognition for his outstanding dedication to the study of life. The name is a noun in the genitive case.

Diagnosis. Dolistenus garciaparisi sp. with transverse furrow almost continuous, clearly interrupted in D. savii , absent in D. humicolus and D. iberoalbus ( Fig. 4 ). Coloration in life variable from pink to reddish brown, yellow in D. savii , whitish in D. iberoalbus ( Fig. 1 ). Metazonites narrow, about twice as long as wide, not 2.5 – 3 X long as wide as in D. savii . Antennal micropores of two sizes, only one size in D. savii and D. iberoalbus ( Fig. 3-a3, b3, c3 ). Anterior gonopod with medial process of sternite broad and widely produced anteromedially as to reach coxae of leg pair 7, smaller and less produced in D. savii and D. iberoalbus ( Fig. 5 ).

Description. Male holotype 13 mm long, 0.6 mm maximum wide (including paranota), with 47 rings including collum, one apodous penultimate ring and telson (preanal ring). Length of male paratypes 12–17 mm, width (including paranota) 0.6 mm, 42–59 body rings including telson. Length of female paratypes 13–22 mm, width (including paranota) 0.6–0.7 mm, 45–66 body rings including telson. Coloration in life pink to reddish brown, with a subtriangular patch of dark reddish color at vertex. Coloration, after one to twelve years in alcohol, with a pale reddish background, more intense in paranota and spot at vertex still marked.

Head densely covered with minute setae, oval-shaped, clearly longer than wide, length-width ratio = 1.2 ( Fig. 3-a 1 ). Antennae short, clavated, elbowed between antennomeres 3 and 4; relative length of antennomeres 6>2>5>3=4>7>1; antennomere 6 enlarged, appearing much larger relative to others ( Fig. 3-a 2 ). Four apical sensory cones. Antennal tegument densely covered by setae and by micropores of two different sizes, the smaller ones with higher density than larger ones ( Fig. 3-a3 ).

Collum as wide as head, trapezoidal, about 2 times as broad as long, posterior margin wider, lateral angles rounded.

Body rings with a longitudinal, medial sulcus starting on ring 2. Prozonites without setae, marked by a series of 4 or 5 rows of scale-like flat tubercles forming circular striae and, closer to the metazona, 2 or 3 rows of papillae. Metazonites from ring 5 backwards ( Fig. 4a ) with a transverse, broad furrow barely interrupted along medial sulcus. Surface of furrows densely covered with papillae, elevated areas with minute setae. Paranota small, covered with minute setae and papillae, in rings 2–5 directed forward; in midbody rings subquadrate with anterior angle more rounded than posterior one; in rings from last third of body posterior angles are produced backwards, more so in terminal rings. Metazonal limbus dentated, tooth-like tabs almost obsolete in the middle part ( Fig. 4a ) Ozopores with thin peritremata, opening marginally and close to posterior angle, except first pair in ring 5 which is centered at margins. Pleura covered with large, scale-like papillae.

Legs short, a little longer than half of width of midbody rings, composed of 6 podomeres sparsely covered with setae, and a single claw. Leg pairs 1–4 with tarsal combs. Sternites with single, medial digitiform processes. Coxal sacs present.

Males with two pairs of gonopods directed anteriad, form typical of Dolistenus ( Fig. 5a ). Anterior gonopods irregularly covered with long setae; medial process of sternite broad, widely produced anteromedially as far as coxae of leg pair 7. Podomere 2 (prefemur in Mauriès 2015) lacking of any parasagittal expansion. Podomere 6 (metatarsus in Mauriès 2015) ending in a broad, rounded lamella. Posterior gonopods also 6-segmented, covered with sparse long setae. Coxite much broader than other podomeres. Telopodites abruptly curved mediad between podomeres 2 (prefemur) and 3 (femur) and anteriad at base of podomere 6 (metatarsus). Podomere 6 ends in a long, fragile forked lamella with no flagella.
