Non-types.

1 ♂, 5 ♀ (CUMZ), Singapore, Central Region, Nature Reserve, Bukit Timah, 1°35'18"N, 104°18'0"E, 25.12.2009, leg. C. Sutcharit.

Descriptive notes.

Length 34–35 (♂) or 3.3–3.6 mm (♀), width of midbody pro- and metazona 2.5–2.6 and 3.9–4.4 mm (♂), 3.4–3.6, and 4.8–4.9 mm (♀), respectively.

Coloration of live animals (Fig. 58A) uniformly blackish brown with only slightly lighter paraterga, venter and legs; coloration of alcohol material upon long-term preservation faded to a light brown (holotype) with contrasting pallid paraterga, venter, legs and antennae (Fig. 57); coloration of rather freshly alcohol-preserved material blackish brown with likewise strongly faded paraterga, venter and legs (Fig. 58B-H).

Remarks.

The original description of this species was so complete and detailed (Hoffman 1973) that no redescription seems to be necessary. Instead, we only provide new illustrations (Figs 59–61) showing the coloration, structural details, and gonopod conformation of Orthomorpha murphyi, based both on the holotype and new samples.
