A mountain of millipedes VI. New records, new species, a new genus and a general discussion of Odontopygidae from the Udzungwa Mts, Tanzania (Diplopoda, Spirostreptida, Odontopygidae) Author Enghoff, Henrik text European Journal of Taxonomy 2018 2018-01-11 394 1 29 journal article 31016 10.5852/ejt.2018.394 54a11801-d3d3-4b76-9f6c-7a9c27677825 1146158 94028C61-FAC5-4A21-BF2D-A75BBF3CCC4D Hoffmanides dissutus ( Hoffman, 1963 ) Figs 7–8 Spinotarsus dissutus Hoffman, 1963: 1 . Hoffmanides dissutus – Kraus (1966) : 135 . Material studied (total: 6 ♂♂) TANZANIA : 6 ♂♂ , Iringa–Morogoro Regions , Udzungwa National Park , 350 m a.s.l. , 8 Dec. 1995 , Steven Liselli leg. ( VMNH ; 1 ♂ , ZMUC ). Description Male Based on studied specimens. Details from previous descriptions ( Hoffman 1963 ; Kraus 1966 ) in parentheses. Considering that two detailed descriptions of H. dissutus are thus available, and that the studied specimens agree completely with both of them, only a few details are highlighted here. SIZE. Diameter 3.5–3.9 mm ( 3.7 mm ); 61–64 podous rings, no apodous rings in front of telson (“56 Segmente”). HEAD. Without peculiarities. Five supralabral setae (6). COLOUR. After 22 years in alcohol, overall yellowish ( Fig. 7 ); prozonites from ozopore level up to ca ⅔ of distance to midline blackish; also a thin blackish midline, i.e., dorsum with two paramedian yellow bands. Fig. 7. Hoffmanides dissutus ( Hoffman, 1963 ) , ♂, from Udzungwa Mts National Park. Photograph by A. Illum. Scale bar = 5 mm. ANAL VALVES ( Fig. 8A–B ). Dorsally drawn out into pointed, triangular, spine-like process, ventrally with small protruding knob; mesal margin raised, setiferous tubercles, especially middle one ( stu ) on pronounced “ravelins”.

Gonopod telopodite, posterior-mesal view. Abbreviations: ssb = spine-like side branch of solenomere, nested in cavity of telomere; stu = middle setiferous tubercle on “ravelin”; tm = tip of telomere. Scale bars: A–B, D = 0.2 mm; C = 0.001 mm; E = 0.1 mm. LIMBUS ( Fig. 8C ). With long, spine-like lobes. GONOPOD COXA ( Fig. 8D ). As illustrated by Hoffman (1963) and Kraus (1966) . GONOPOD TELOPODITE ( Fig. 8E ). As illustrated by Kraus (1966) . In some specimens the solenomere is hidden within the telomere ( Fig. 8E ), but in others the solenomere has come free (due to preservation?), and the long, spine-like branch ( ssb ) arising from it, overlooked by Hoffman (1963) but illustrated by Kraus (1966: fig. 358) , is obvious. Female Unknown. Distribution Helicochetus dissutus was described from “ Morogoro ” ( Hoffman 1963 ); this does not necessarily refer to the city of Morogoro , ca 150 km NE of Udzungwa National Park, but possibly to anywhere in the Morogoro Region . Enghoff et al. (2016) also recorded the species from the Morogoro Region , Uluguru Mts, Morningside.
