Taxonomic Remarks

Forms a cryptic species complex with co-occurring Micrurides sp. SMTM030 and SMTM031, from which it can only be distinguished by COI sequence data (>10% divergence). The clade also includes a morphologically similar undescribed species from Oman, Lineidae sp. SMOM073 (Maslakova et al. 2025 PeerJ 13e:19438). The clade is tentatively affiliated with Micrurides based on the preliminary phylogenetic analyses, and presence of the transverse cephalic furrows.

Description of Material

Body 3-6 mm long, 0.3-0.6 mm wide; slender when stretched out, widest at posterior margin of cephalic slits, gradually tapering toward a short caudal cirrus; semi-transparent; background colour dilute orange, deeper dorsally, especially on cephalic lobe, gradually fading to flesh colour in the posterior 1/2 of body. Cephalic lobe about three times as long as it is wide, shaped as a rounded rectangle, with a band of opaque white at anterior tip (visible from all sides). White colour reaches to about 1/5th of the length of cephalic slits. Cephalic margins translucent. Inconspicuous transverse furrows present at posterior margin of lateral cephalic slits. Ocelli lacking.

Ecology

Associated with coral rubble.

Distribution

Only known from Atauro Island, Timor-Leste.
