Tajikacelis tajikai n. sp.
( Figs 1A View FIGURE 1 , 2A View FIGURE 2 , 3 View FIGURE 3 , 10A View FIGURE 10 )
Diagnosis. Species of Tajikacelis with a curved stylet, 58–63 μm long (N=5), with a proximal opening of 30–34 μm, narrowing to 8–10 μm at around 1/3 of its length and 3–4 μm wide close to its end and widening again to around 5 μm. With a truncated distal opening. Testes in a single row, 12–13 in front of the ovaries and about 30 from ovaries to the pharynx. Postpenial widened female duct with a dorsal vagina.
Occurrence. South George Beach , Point Lookout, Stradbroke Island, Queensland Australia (27°26’10.8”S; 153°32’36.2”E), lower intertidal in a slightly protected area of the beach, with medium sand (type locality)(13 August 1996 by M.C-G.) GoogleMaps .
Material studied. Several animals studied alive, five whole mounts, one of which holotype ( QM G23851); the other four and 11 sectioned individuals are paratypes ( CZM809-823 ) .
Etymology. the species name honors Dr. K-I. Tajika.
Additional remarks. With a thin band of brown pigment running from the tip of the snout to the statocyst. The common female duct, widened into a bursa, is surrounded by a weak muscle layer and lined with a rather high epithelium that becomes lower towards the pore. Between the pore and the level of the copulatory organ, a dorsal vagina is present. The vaginal duct is short and broad, lined with a low epithelium. Just in front of the copulatory organ a cluster of glands opens at the ventral surface. The female cement glands around the female pore are exceptionally large. A short genito-intestinal duct behind the female pore leads directly to the intestine, whose posterior end shows resorbing features.
Karyology. n=7. With five pairs of chromosomes slightly differing in size: three pairs of which are metacentric, and two pairs acrocentric; and with two much smaller chromosome pairs, one of which metacentric, the other acrocentric ( Fig 3E–F View FIGURE 3 ).
