38 (see Figure 786) first segment crescent-shaped, produced at posterior corners to envelope anterior half of second segment; segments measure (1 X w) 1.01 X 1.50 mm, 1.02 X 1.10 mm respectively. Caudal rami longer than wide (0.65 X 0-43 mm) similar to E. brachyptera. First antenna (Figure 78
NUMBER 311 39 a partially dissected male was in the vial when we received it from the Australian Museum. Examination of this specimen and Heegaard's figures of the female lead us to believe that this species was erroneously placed in the Euryphoridae by the author. His basis for doing so was the presence of dorsal plates covering the fourth thoracic segment. His figures do not indicate these and the male specimen does not have them. Unfortunately, lacking the female, we could not resolve the problem of its true taxonomic position. We hope that additional material of this interesting species will be collected eventually and its taxonomic position made clear. We have refigured the male maxilliped (Figure 80c), sternal furca (Figure SOd), leg 1 (Figure 80*), and leg 2 (Figure 80f). The original collection was made from the body surface of Euthynnus affinis (reported as E. alletteratus) from Howick Island, north Queensland, Australia. The total length of the male is 3.35 mm. Tuxophorus Wilson, 1908 Tuxophorus cybii Nunes-Ruivo and Founnanoir, 1956 FIGURE 81a Tuxophorus cybii Nunes-Ruivo and Fourmanoir, 1956:76. Tuxophorus solandri Kurian, 1961:72. We did not collect this species but we have reproduced the figure of the female based on the illustration of Nunes-Ruivo and Fourmanoir. In 1961 Kurian described a new species, T. solandri, based on a single specimen from the body surface of Acanthocybium solandri from India. Kurian was apparently unaware of the description of T. cybii earlier as he made no mention of it. Comparisons of the 2 descriptions leave no doubt that they represent the same species and, consequently, we have placed Kurian's T. solandri in synonymy with T. cybii. Furthermore, we suspect that T. cervicornis of Heegaard (described below) may also be a synonym of T. cybii. The only difference we find between Heegaard's species and T. cybii and T. solandri is the highly developed processes on the outer distal corners of T. cervicornis (absent in the other 2). This could be accounted for if the descriptions of T. cybii and T. solandri are based on immature specimens. Each description is based on a single specimen and neither Nunes-Ruivo and Fourmanior or Kurian show egg strings in the illustrations (Heegaard does). One of our collections of T. cervicornis is from Pakistan, extending the range of that species to within the known range of T. cybii. Since we did not collect specimens of T. cybii or immature T. cervicornis we feel it would be premature to place T. cybii in synonymy. We trust that future collection will bear out our suspicions regarding the synonymy of these 2 species. Tuxophorus cervicornis Heegaard, 1962 FIGURE 81 b-g Tuxophorus cervicornis Heegaard, 1962:172. MATERIAL EXAMINED.—2 collections containing 2 9 from the body surface of Scomberomorus commerson from Coffs Harbor, New South Wales, Australia, and Karachi, Pakistan. FEMALE.—Body form as in Figure 81fe. Total length 6.80 mm. Greatest width 3.15 mm. Cephalon slightly longer than wide (3.10 X 3.15 mm). Thoracic segment bearing leg 4 with dorso-lateral winglike plates. Genital segment slightly wider than long (2.10 X 2.25 mm, including posterior processes) ; outer posterior corners produced. Abdomen 3-segmented. Caudal ramus about 6.5 times longer than wide (1.95 X 0.30 mm). Oral appendages as in T. collettei except sternal furca with pointed tines (Figure 81tf) rather than spatulate. Leg 1 as in T. collettei except spinules on terminal spines thicker in T. cervicornis. Legs 2-3 as in T. collettei. Leg 4 (Figure 81g) exopod 3-segmented, terminalmost spine shorter (relative to adjacent spine) than in T. collettei. MALE.—Unknown. REMARKS.—This species has been reported from Scomberomorus commerson from northern Australia and Pakistan. See the discussion following the description of T. cybii for comparisons with that species.
