Ordo: Polydesmida

Name
Eustrongylosoma mirabile Golovatch & Stoev, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype♂(NMNHS),Papua New Guinea, West Sepik Province, Telefomin area, 1700 m, September 1975, B.S.E. (leg. P. Beron). – Paratype: 1 ♂ fragment(NMNHS), same locality, together with holotype.
Name
To reflect the beautiful appearance.
Diagnosis
Distinguished by the rugulose to rugose caudal halves of metaterga and the relatively thin paraterga (see also Key below).
Description
Length ca 20 mm (holotype), width of pro- and metazona 1.5 and 2.0 mm, respectively (both holo- and paratype). Coloration uniformly light yellow-brownish to brownish.
In width, head >> collum = segment 3 = 4 < 2 < 5–16. Head densely setose, only vertex with 1+1 setae. Antennae rather short, slightly clavate, reaching midway of segment 3 dorsally; antennomere 2 longer than 6th. Collum transversely oval, lateral flaps small, regularly and broadly rounded. Tegument generally smooth and shining, only below paraterga faintly microgranulate; rear halves of metaterga rugulose to rugose longitudinally. Paraterga of postcollum segments relatively well developed (Figs 55, 56), narrow, only slightly thicker in pore-bearing segments than in poreless ones, set low (at about 1/2 midbody height), with a clear undulation in front of ozopore near caudal third to quarter; paraterga 2 with a small anterolateral indentation, following ones often with a minute indentation or puncture near midway. Caudal corners of postcollum paraterga mainly nearly pointed to pointed, beak-shaped, mostly not or only barely extending beyond rear tergal margin, evidently extending behind it only on segments 16–19. Lateral calluses of paraterga medium-sized, somewhat narrower in poreless segments, delimited by a sulcus dorsally, in pore-bearing segments ventrally in caudal 1/3–1/4 as well. Ozopores lateral, placed inside an ovoid groove. Tergal setae mostly abraded, medium-sized (ca 1/3 metatergal length), setation pattern traceable at least as 1+1 paramedian insertion points in front row. Axial line weak, traceable only on some metaterga, especially so in caudal halves. Transverse sulcus on metaterga rather superficial, incomplete, not reaching bases of paraterga, visible on metaterga 5–18. Stricture between pro- and metazona evidently beaded. Pleurosternal carinae small, well visible only in segment 2, reduced in 3rd, thereafter entirely missing. Epiproct (Fig. 57) short, flattened dorsoventrally, digitiform; apical papillae small, tip narrowly subtruncate; subapical papillae very small, removed from tip. Hypoproct (Fig. 58) semi-circular, setigerous paramedian knobs at caudal margin well-separated and very small.
Sterna rather sparsely setose; a rather high, linguiform, roundly subtruncate, ventral, setose lamina only between coxae 4 (Fig. 59). Legs long, midbody ones ca 1.9–2.0 times longer than body height, apparently somewhat incrassate and longer compared to ♀; ♂evident tarsal and distotibial brushes increasingly well reduced towards legs of segment 19.
Gonopods as in Figs 60 & 61. Distal third of solenophore split into a lateral lobe (k) and a large branch/lobe (j) of irregular shape. Apicolateral lobe (l) of femorite rounded, rather low.
