- Orthomorpha unicolor – Jeekel 1963[3]: 265 (M); 1964[4]: 361 (M); 1968[5]: 45 (M); Hoffman 1973[6]: 362 (M); 1977[7]: 700 (M); Golovatch 1998[8]: 42 (D, M).
Holotype
♂ (NHMW-3508), Indonesia, central Java, Sarangan, 09.12.1928, leg. A. F. Thienemann & H. J. Feuerborn.
Redescription
Length ca 29 mm, width of midbody pro- and metazona 2.2 and 3.3 mm, respectively. Coloration of alcohol material upon long-term preservation rather uniformly brown (Fig. 39) (vs very dark brown, as given in the original description (Attems 1930a[1])).
All other characters as in Orthomorpha hydrobiologica, except as follows.
Collum with three transverse rows of setae, 4+4 anterior, 2+2 intermediate, and 2+2 posterior setae; caudal corner of paraterga subrectangular, narrowly rounded (Fig. 39A & B). Postcollum metaterga with two transverse rows of setae traceable as insertion points: 2+2 in anterior (pre-sulcus) row, 4+4 in posterior (postsulcus) one, the latter borne on small tubercles. Paraterga strongly developed (Fig. 39A-G), mostly subhorizontal and lying below dorsum, on postcollum segments extending increasingly beyond rear tergal margin, always pointed, on segments 16–19 tips strongly curved mesad. Calluses on all paraterga delimited by a sulcus only dorsally, rather broad, especially so on pore-bearing segments. Paraterga 2 broad, anterior edge rounded, lateral edge with only one small incision near midway (Fig. 39A). Transverse sulcus complete on metaterga 5–18, shallow, not reaching bases of paraterga, ribbed at bottom, slightly sinuate anteromedially (Fig. 39A, C & F). Pleurosternal carinae complete crests only on segments 2–4 (Fig. 39B), each with an evident sharp denticle caudally, thereafter increasingly strongly reduced until segment 10.
Sterna sparsely setose, with neither modifications nor knobs between ♂ coxae 4 (Fig. 39H & I). Gonopod aperture damaged during removal of gonopods. Legs long and slender, midbody ones ca 1.3–1.4 times as long as body height, prefemora without modifications, tarsal brushes present until ♂ legs 10.
Gonopods (Fig. 40) with prefemur enlarged, about 2 times shorter than femorite + “postfemoral” part.
Remarks
This variety was elevated to a full species by (Jeekel (1963[3], 1964[4], 1968[5]), also treated as such by Hoffman (1973)[6] and Golovatch (1998)[8].
