Holotype ♀ ( USNM 1027325 ), associated with Tubipora musica collected in Nosy Bé , Madagascar , 05, January 1964 . Description of female. Urossome 3-segmented ( Fig. 3D ). Genital double-somite fused with fifth pedigerous somite forming genital complex, 150 µm long and maximum width anteriorly, 133 µm , length: width ratio = 1.1:1, vestigial leg 6 located anterolaterally with seta, close to genital openings, at 1/3 of the anterior margin. Setulated groove mid-posteriorly on genital somite, reaching posterior margin. Two postgenital somites present. First and second abdominal somites 52 × 57 and 63 × 61 µm , respectively. Posterior margin of anal somite concave at insertion of caudal rami. Caudal rami convergent, and gradually broadening distally, 110 × 19 µm . Length: width ratio 5.8:1, armed with 6; setae I absent. Leg 5 formed by basal segment, enlarged proximally, armed with small, naked seta on outer margin and distal thin segment with 3 naked setae. All other appendages as in original description by Kim (2004) , except for the antennal exopod and the outer lobe of the maxillula which we were unable to study due to the quality of the slide. Remarks. The female of Entomopsyllus stocki was described by Kim (2004) based on a single specimen dissected and mounted on permanent slide. In this revision only the genital complex showed differences to the original description ( Kim 2004 ), that was described as unfused to the fifth pedigerous somite. A careful reexamination indicates that the fifth pedigerous somite is fused, forming a genital complex. The setuled groove in the mid-posterior region was not described originally, as well.
