Enghoff, Henrik & Reboleira, Ana Sofia P. S., 2019, The genus Jeekelosoma Mauriès, 1985 - Moroccan cave millipedes (Diplopoda, Polydesmida, Paradoxosomatidae), European Journal of Taxonomy 523, pp. 1-16 : 2-3

Genus Jeekelosoma Mauriès, 1985 stat. nov.

Jeekelosoma Mauriès, 1985: 52 , as subgenus of Eviulisoma Silvestri, 1910 , type species: Eviulisoma (Jeekelosoma) abadi Mauriès, 1985 .

Diagnosis

A genus of small, depigmented species ( Fig. 1 ) of the tribe Eviulisomatini sensu Enghoff (2018) . Differs from contribal genera by the strongly modified peritremata bearing the ozopores and by the horizontal or oblique row of denticles on each side of each podous body ring. Further differs from contribal genera except Boreviulisoma Brolemann, 1928 , by having three transverse rows of setae on postcollar rings.

Included species:

Jeekelosoma abadi ( Mauriès, 1985) comb. nov.

Jeekelosoma heptarachne sp. nov.

Jeekelosoma viginti sp. nov.

Distribution

Morocco, in caves.

Key to the species of Jeekelosoma

1. Adults with 20 ‘segments’ (17 podous rings + 1 apodous ring + telson) ................ J. viginti sp. nov.

– Adults with 19 ‘segments’ (16 podous rings + 1 apodous ring + telson) ......................................... 2

2. Peritremata ovoid, mushroomlike ( Fig. 2G ), leg femora shorter than body height, gonopod solenophore with a curved terminal appendage ( Fig. 4 ) ........... J. abadi ( Mauriès, 1985) comb. nov.

– Peritremata cylindrical ( Fig. 6 G–H), leg femora longer than body height, gonopod solenophore without a terminal appendage ( Figs 7–8 ) ..................................................... J. heptarachne sp. nov.
