External morphology. Body elongate with parallel margins. Anterior tip blunt and posterior end pointed (Figs 1, 2). Dorsal surface light olive green, stippled with dark gray fine spots, and body margins and cephalic region pigmented dark gray (Fig. 1). Ventral surface whitish with margins grayish. After fixation, the dorsal color pattern became paler with lighter gray fine spots. Eyes distributed from the anterior tip to the posterior end. They surround the cephalic region and extend uniserially on body margins along 1-2 mm from the anterior tip, continuing pluriserially over the dorsal surface, being surrounded by clear halos. Eyes occupy about 30% of body width on each side of the dorsal surface at pre-pharyngeal region. Behind the pharynx, they decrease in number and at the level of the copulatory apparatus become uniserial

The numbers given in parentheses represent the position relative to body length (%). Thickness (µm) of cutaneous (CM) and parenchymatic (PM) musculatures at pre-pharyngeal region. CMI (cutaneous muscular index): ratio between height of cutaneous musculature to body height. PMI (parenchymatic muscular index): ratio between height of parenchymatic musculature to body height. Both indices measured at pre-pharyngeal region.
