Material. IV0000261316 (Holotype DNA sample HY11) mature, sketched and dissected from Jeombongsan Mt , (37̊01′16.39′′N 128̊25′6.36′′E), collected by Dr H.-Y. Seo, 25 th July, 2013 ; IV0000261317 (Paratype), superficially similar mature, same details; plus sample contained a mature M. hilgendorfi specimen IV0000261315 with everted male pores (confirming its correct allocation to genus Metaphire ). Other sample batch with same details contains three specimens (IV0000216318-20) that agree superficially except they may have three instead of two papillae in 7 and 8, the longest is 120 mm; two other samples are IV0000216321 and sympatric specimen described successively below .

Etymology. Derived from Morse code for its spermathecal markings: “.. - ..”=ITI.

Description. Length 111 mm (both H & P). Reddish iridescent dorsum body tapers to tail. Epilobous. First dorsal pore 12/13. Perichaetine with 50-60 setae. Clitellum 14-16. Spermathecae in 6/7/8 just above intersegment in lateral dark patches with transverse row of two sets of two GM papilla below and median to each pore (sets of two and three in some specimens). Female pore single, central on clitellum. Male pores just behind setal line in dark elongate patches two rows of about six papillae above and medial to each porophore. Spermathecal ampullae deflated with clavate diverticulum on muscular duct and GM glands nearby. Prostates racemose on muscular duct. GM glands correspond internally to the male GM papillae. Seminal vesicles large in 11 and 12. Caeca manicate in 27.

Remarks. The nearest Blast result for HY11 is also just 87% for Metaphire communissima (Genbank AB542623.1 from Hyogo-ken, Japan), and HY11 vs. HY9=568/653 (87%).

Distinctive characters of A. iti are the markings that also resemble nesting birds (see figure) and the slightly off-line position of the spermathecal and male pores. DNA data helps confirm this identity amongst taxa tested.
