Colouration of live animals ( Fig. 6A View Figure 6 ) black-brownish with contrasting dark yellow to orange paraterga and epiproct, head and antennae brownish, legs pale brownish; colouration in alcohol, after one year of preservation, faded to black-brown ( Fig. 6 B–H View Figure 6 ), paraterga and epiproct pale whitish yellow or pale brown, legs whitish to pale brown distally.
Remarks.
This species has recently been redescribed ( Likhitrakarn et al. 2011), based on type material. The new specimens agree nearly fully with the available descriptions except for the ♂ tarsal brushes being present until legs 7 or 8 vs. legs 5. One variety, grandis var. nov., is more disjunct morphologically, but not genetically, being treated separately below.
This species seems to be widespread, occurring in Vietnam and northern Laos ( Fig. 19 View Figure 19 ), and in two places it was found coexisting with O. rotundicollis (Attems, 1937) (see also above).
According to IS’ field observations, the millipedes occupy a wide range of habitats, including riparian forests with flooding occurring every year and non-flooding mixed forests on slopes. They also appear in a forestless farm area, usually being found on the forest floor and at bases of tree trunks. They occupy many microhabitats in lower forest strata. The activity is mainly restricted to the night time, but some individuals keep it up in daylight as well.
