B746B31BFFB0E73AF1BD614D73BBFC6B.taxon	etymology	Etymology From the Latin viātor (traveller), in reference to its wide, disjunct distribution. The name is a masculine noun in the nominative singular.	en	Recuero, Ernesto, Rodríguez-Flores, Paula C., Giribet, Gonzalo (2024): Surfing in the Eastern Atlantic: a new bristle millipede from Iberia and the Canary Islands with insights into the phylogeny of Lophoproctus (Diplopoda: Polyxenida: Lophoproctidae).

B746B31BFFB0E73AF1BD614D73BBFC6B.taxon	diagnosis	Diagnosis Morphologically similar to Lophoproctus lucidus (Chalande, 1888), particularly in the disposition of basiconic sensilla on antennomere VI (Figures 5 C, 7 B, 8 B) and the ornamentation of the labrum (Figures 4 C, 7 A, 8 A), it differs in the presence of two ventral, basal acute denticles in the claw of telotarsus (Figures 6 H, 6 I, 7 D); also in having the two median pairs of labral linguiform processes with pointed apex (Figures 4 C, 7 A), with only the medianmost pair pointed in L. lucidus (Figure 8 A). In life, L. lucidus shows a conspicuous, elongated red spot on both sides of the head, below the trichobothria, that is not observed or is very faint in L. viator (Figure 2). Lophoproctus pagesi also has paired claw ventral processes, but they are robust while these are slender in the new species; the two species differ in the disposition of basiconic sensilla on antennomere VI (Condé 1981). Both L. jeanneli and L. israelensis differ from the new species by having a denticle in the telotarsus claw and no ventral processes (Condé 1981; Short 2020). Lophoproctus coecus shows a different disposition of the basiconic sensilla on antennomere VI and lacks ventral processes in the claw (Nguyen Duy-Jacquemin 1993; Short 2015).	en	Recuero, Ernesto, Rodríguez-Flores, Paula C., Giribet, Gonzalo (2024): Surfing in the Eastern Atlantic: a new bristle millipede from Iberia and the Canary Islands with insights into the phylogeny of Lophoproctus (Diplopoda: Polyxenida: Lophoproctidae).

Vertex with two paramedian trichome groups formed by single rows of 11 – 12 trichomes plus 1 trichome posteriorly, distance between each pair of rows shorter than their length. Anterior part of vertex homogeneously covered with slender, barbate trichomes. Each side of head with 3 trichobothria arranged in an isosceles triangle; the posteriormost ones thinner and more acute than the anterior one. Gnathochilarium palps with 37 – 41 sensilla in males, 18 – 20 in females. Labrum (Figures 4 C, 7 A) with 10 – 11 linguiform processes on each side; the two median pairs with pointed ends; external surface of labrum ornated with two transverse rows of irregularly shaped, broad ridges. Antennae (Figure 5). Eight antennomeres, relative lengths: III <I = V = VII <II <IV = VIII <VI. Antennomere VIII with 2 apical and 2 subapical striated sensory cones. Antennomere VII with 2 long basiconic papilla (Figures 5 D, 7 C), subequal in length, inserted at the same level. Antennomere VI with 4 long basiconic sensilla (Figures 5 C, 7 B), subequal in length, the first two set at the same level on the antennomere, sensilla 3 rd and 4 th set higher and at slightly different levels; the 4 th may be set higher or lower on the antennomere than the 3 rd. Trunk. (Figure 3). Collum with a subrectangular tergite showing a glabrous central part and two-thirds covered with 42 – 48 trichomes on each side arranged as lateral rosettes; lateral protuberances each with an anterior row of 5 trichomes and 2 posterior trichomes. Remaining tergites with trichomes arranged in a continuous posterior row (Figure 6 A) and lateral transversely ovoid rosettes where trichomes are aligned in three irregular rows: Lateral protuberances with rounded trichome rosettes. Caudal pencil (Figure 6 B) with no sexual dimorphism. Legs. (Figure 6 C – I). Legs with 8 podomeres, except legs 1 with 6 podomeres, lacking trochanter and basitarsus, and legs 2 and 13 with 7 podomeres, lacking trochanter. Coxae with 2 ribbed oval setae, except coxae 1, 2, 12, and 13 with 1; prefemora and femora with 1 ribbed oval setae. Tarsal spine longer than claw. Claw of telotarsus with paired, blunt dorsal tubercles and paired, acute ventral denticles (Figures 6 H, 6 I, 7 D); ventral profile not showing any denticle.	en	Recuero, Ernesto, Rodríguez-Flores, Paula C., Giribet, Gonzalo (2024): Surfing in the Eastern Atlantic: a new bristle millipede from Iberia and the Canary Islands with insights into the phylogeny of Lophoproctus (Diplopoda: Polyxenida: Lophoproctidae).

B746B31BFFB0E73AF1BD614D73BBFC6B.taxon	discussion	Remarks The new species is morphologically similar to Lophoproctus lucidus, matching in several important characters such as the basiconic sensillar arrangement in antennomere VI or the ornamentation of the labrum. For this reason, L. viator sp. n. was initially assigned to L. lucidus by Recuero and Rodríguez-Flores (2023).	en	Recuero, Ernesto, Rodríguez-Flores, Paula C., Giribet, Gonzalo (2024): Surfing in the Eastern Atlantic: a new bristle millipede from Iberia and the Canary Islands with insights into the phylogeny of Lophoproctus (Diplopoda: Polyxenida: Lophoproctidae).
