Fig. 2 View FIGURE 2 I–L

Holotype: SIO-BIC A3651 hologenophore (1 spm: ½—in 70% ethanol after formalin fixation; ½—95% ethanol). Padoz Reef, Madang Harbor, Papua New Guinea (5° 9' 34.8006"S, 145° 48' 46.2096"W), 5– 20 m. Collected using scuba on 27 November 2012 by MMS and GWR. Genbank (COI—KM014176).

Host. Clarkcomanthus alternans (Carpenter) ( Comatulidae , Comatulida , Crinoidea). MNHN-IE-2013-8114 (dried voucher); SIO-BIC E5879 (tissue subsample in 95% ethanol). Genbank (COI—KM491773).

Paratypes: SIO-BIC A3652 syngenophores (3 spms: 2—in 70% ethanol after formalin fixation; 2—95% ethanol). Same location as holotype. Genbank (COI—KM491743). Host: Clarkcomanthus mirabilis (Rowe et al.) , MNHN-IE-2013-8174 (dried voucher) & SIO-BIC E5880 (tissue subsample in 95% ethanol); Genbank (COI—KM491774). SIO-BIC A3653 syngenophores (2 spms: 95% ethanol). South Padoz Reef, Madang Harbor, Papua New Guinea (5° 9' 43.1994"S, 145° 48' 59.3922"W), 5– 20 m. Collected using scuba on 1 December 2012. Genbank (COI—KM491744). Host: Comatella nigra (Carpenter) , MNHN-IE-2013-8064 (dried voucher) & SIO- BIC E5891 (tissue subsample in 95% ethanol); Genbank (COI—KM491775).

Etymology. Named for Deborah Lanterbecq, who first sequenced DNA from a Mesomyzostoma and led the work resulting in the first molecular phylogeny for myzostomids ( Lanterbecq et al. 2006).

Diagnosis and description. Located within host’s coelom. Holotype body thin and elongate. Length ~ 2.5 mm following fixation (specimen cut and curled) [paratypes 2–4 mm]. Body margin acirrate. Mouth and cloaca terminal. Five pairs of small parapodia, with large hooks ( Fig. 2 View FIGURE 2 L). Color cream in life, white in preservative.

Remarks. There are nine other species of Mesomyzostoma —two described, Mesomyzostoma katoi Okada, 1933 and Mesomyzostoma reichenspergeri Remscheid, 1918 , and four currently being described Eeckhaut et al. (in prep) and three undescribed species in Summers & Rouse (2014). All of these species have a similar body form and occupy the coelom and/or gonads of feather star crinoids. The species are best distinguished by molecular data, followed by host use. This is likely a highly undersampled lifestyle due to the requirement of dissection.
