Lubbockia squillimana Claus 1863
Description
Lubbockia squillimana Claus, 1863
Figures 9–17
Synonymy (Heron and Bradford 1995): Lubbockia minuta Marukawua 1927; Lubbockia marukawuai Mori, 1937.
Material examined. One female, dissected (UARC 294- UARC 301M).
Remarks. Body slender, elongate (Fig. 9). Body length = 1325 µm. The Colombian specimens bear the diagnostic features of L. squillimana as reported by Boxshall (1977) and Boxshall and Halsey (2004) and can be easily recognized by: 1) antennule 5-segmented (Fig. 10), 2) maxilliped with large denticles on the basis (Figs 11, 12), 3) P1-2EXP3 with 2 outer spines (Figs 13, 14), 4) P5 elongate, reaching beyond posterior margin of genital double-somite (Figs 15, 16), 5) genital double-somite much longer than succeeding postgenital somite (Fig. 16), 6) P6 represented by single setal element (Fig. 17).
Lubbockiids are oceanic copepods, occurring in open waters and often at great depths (Heron and Damkaer, 1978). Lubbockia squillimana is epipelagic (Heron and Bradford-Grieve 1995) but has been also found at mesobathypelagic depths (Berdugo and Kimor 1968). In the Caribbean Sea, L. squillimana can be confused with L. aculeata Giesbrecht, 1891; they can be separated by: 1) the structure of the female P5 which reaches the posterior border of the genital double-somite in L. squillimana and is shorter in L. aculeata, 2) L. squillimana female maxilliped lacks inner spinous processes on the basis whereas such processes are present in L. aculeata.
Variability. The right maxilliped of our specimen bears 2 large denticles instead of 4 (Fig. 12). Heron and Damkaer (1969) reported a similar variation of the maxilliped in L. wilsonae.
Distribution. Lubbockia squillimana has a tropical distribution, but it is also found outside tropical waters (Heron and Damkaer 1978). In Colombia this species has been reported in Providence and Santa Catalina islands (Martínez-Barragán et al. 2009). This is the first record of this species in the Magdalena department, northern Colombia.
