Taxonomic Remarks

Forms a cryptic species complex with co-occurring Micrurides spp. SMTM029 and SMTM030, from which it can be distinguished by COI sequence data. 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. Most closely related to Micrurides sp. SMTM030, from which it differs by COI sequence divergence of 8-9%.

Description of Material

Body up to 18 mm long, 0.25-0.4 mm wide; slender when stretched out, widest at posterior margin of cephalic lobe, gradually tapering toward a short caudal cirrus; background colour dilute orange, somewhat darker dorsally, especially on cephalic lobe, fading to flesh colour toward ventral and posterior. Cephalic lobe about 3-4 times as long as it is wide, shaped as a rounded rectangle to trapezoid (slightly wider at its posterior), with a band of opaque white at anterior tip. Width of white band about 1/6th of the length of cephalic slits. Cephalic margins translucent. Inconspicuous transverse furrows present at posterior margin of lateral cephalic slits. Ocelli lacking.

Ecology
