Descriptive notes.

Length 33-42 (♂) or 33-51 mm (♀), width of midbody pro- and metazona 2.6-3.6 and 4.0-6.0 mm (♂), 2.9-4.5 and 4.7-6.7 mm (♀), respectively.

Coloration of live animals (Fig. 75A) blackish-brown with contrasting yellow paraterga and epiproct, most of metaterga being light grey-brown; coloration of alcohol material upon long-term preservation blackish-brown to faded dark castaneous brown with contrasting yellow to pallid paraterga, epiproct and hind halves of metaterga (Figs 74, 75B-H & K-M); pattern mostly light creamy-yellowish, including paraterga’s dorsal and ventral parts, with contrasting dark brown to blackish cingulations of prozona and of anterior parts of metaterga. Collum either completely light or also bearing a dark, oblong, transverse, more or less large spot in front 1/3.

Calluses of several midbody and/or posterior metaterga (16-19) can be less strongly convex laterally (Fig. 75L & M).

Tip of solenophore narrowly rounded to sharply dentiform, rather depending on aspect (Figs 76-78).

Remarks.

The original description of this species was complete and detailed enough ( Golovatch 1998) to require no complete redescription. Instead, we provide new illustrations (Figs 74-78) that show the coloration, structural details and gonopod conformation of Orthomorpha subkarschi , based both on the holotype and new samples. Orthomorpha subkarschi appears to be quite widespread in southern Thailand (Map 3).
