A mountain of millipedes I: An endemic species-group of the genus Chaleponcus Attems, 1914, from the Udzungwa Mountains, Tanzania (Diplopoda, Spirostreptida, Odontopygidae) Enghoff, Henrik European Journal of Taxonomy 2014 2014-10-24 100 100 1 75 TH7L Enghoff, 2014 Enghoff 2014 [629,859,1412,1439] Diplopoda Odontopygidae Chaleponcus Animalia Spirostreptida 64 65 Arthropoda species tintin sp. nov.   urn:lsid:zoobank.org:act: E350A221-3166-45FA-B897-F5A36A31A900  Figs 9, 31, 34    Diagnosis Small. Distinguished from all other species in the  C. dabagaensisgroup by the hook-like tip of the gonopod coxa ( Fig. 9). Gonopod coxa without a lateral process; metaplical shelf-spine long.    Etymology The name is a noun in apposition and refers to a cartoon character developed by the Belgian author Hergé because of the (somewhat remote) resemblance of the shape of the gonopod cucullus to Tintin’s hairstyle.   Material studied(total: 1 ♂)    Holotype  TANZANIA: ♂, Iringa District, Udzungwa Mts, Chervemba, Mufu forest, Ndundulu forest, Udekwa village,  2100 m, montane evergreen forest, in dead wood,  6 Sep. 1991, Louis Hansenleg.

Posterior (-mesal) view. al= anterior telomeral lamella, cu= cucullus, mfp= metaplical flange process, ms= metaplical shelf, mss= metaplical shelf-spine, pl= posterior telomeral lamella, plb= basal branch of pl, ps= proximal spine on solenomere. Scales 0.1 mm.   Type locality  TANZANIA: Iringa District, Udzungwa Mts, Chervemba, Mufu forest, Ndundulu forest, Udekwa village, 2100 m, montane evergreen forest.   Description(male) DIAMETER. 1.6 mm, 41 podous rings. COLOUR. After 23 years in alcohol almost uniform pale brownish, with traces of a pale dorsal band. ANAL VALVES. Each with a strong dorsal spine and a very small ventral one; marginal rim raised, setiferous tubercles inconspicuous, not on ‘ravelins’. LIMBUS. With triangular lobes; lobes slightly longer than wide, striate on outer surface. TARSAL SETATION. Normal GONOPOD COXA ( Figs 9, 31). About 3 × as high as wide. Lateral margin straight, apically curving mesad at right angles, cucullus ( cu) produced in characteristic laterad-curving hook. Metaplical flange ending in triangular process ( mfp). Metaplical shelf ( ms) small and simple; metaplical shelf-spine ( mss) short, thin, sinuous, pointing mesad. GONOPOD TELOPODITE ( Fig. 31). Solenomere with a very small proximal spine ( ps). Telomere with two branches: • a relatively small, subrectangular anterior lamella ( al), • a more elaborate posterior lamella ( pl) with strongly spiny margins and with a basal branch ( plb) ending in long spine; plincluding plbcurving anteriad and best visible in anterior view.    Distribution and habitat The unique holotypewas found in Udzungwa Mts, Chervemba, Mufu forest, Ndundulu forest, Udekwa village.Altitude: 2100 masl (the highest accurate record of the  C. dabagaensisgroup). Habitat: montane evergreen forest, in dead wood.    Coexisting species No further species of the  C. dabagaensisgroup is known from Ndundulu forest. However,  C. basiliscus sp. nov.,  C. circumvallatus sp. nov.,  C. gracilior sp. nov.,  C. ibis sp. nov.and  C. netus sp. nov.also occur in West Kilombero FR to which Ndundulu forest belongs. 2626747312 1991-09-06 ZMUC Louis Hansen Tanzania Udzungwa Mts 2100 Mufu forest Chervemba 64 65 1 1 Iringa District holotype
