DISTRIBUTION. — Eastern tropical Pacific , From Punta Eugenia, Baja California Sur, México to the Galápagos Islands, from intertidal to 45 m depth, in sandy or mixed bottoms.

DIAGNOSIS. — Hesione  with prostomium slightly curved laterally; parapodia with dorsal cirri basally cylindrical, dorsal cirrophore twice as long as wide; larger acicula blackish; acicular lobe single, long, tapered, lower tine rounded, small; neurochaetal blades bidentate, 3-8 times as long as wide; subdistal tooth smaller than distal one, with guards approaching distal tooth.

DESCRIPTION

Holotype, USNM 19379, complete, tapered, colorless in ethanol, slightly macerated with several dorsal cirri and ventral cirri damaged or lost; chaetae from chaetiger 1 lost; body integument finely annulated dorsally, annulations not continued into lateral cushions, especially behind chaetal lobes ( Fig. 33AView FIG). Body 39 mm long, 5 mm wide.

Prostomium as long as wide, anteriorly narrower, expanded towards posterior margin; anterior margin projected, posterior margin with a small furrow ( Fig. 33BView FIG). Antennae minute, blunt, slightly as long as wide. Eyes barely pigmented, anterior ones placed by the middle of the prostomium, slightly larger and farther apart than posterior ones, displaced posteriorly.

Tentacular cirri damaged, longest ones reaching chaetiger 4. Lateral cushions projected, corrugated in anterior region, divided into two sections in posterior region.

Parapodia with dorsal cirri damaged; cirrophore annulated, about twice as long as wide; cirrostyle macerated, looking smooth. Ventral cirri with cirrophores small, indistinct; cirrostyle longer than chaetal lobe. Chaetal lobe thick, with parallel sides, slightly tapered, annulated basally ( Figs 33CView FIG, 34D, EView FIG).

Neuraciculae blackish, two, one markedly thicker than the other. Acicular lobe single, tapered, rarely directed upwards, mostly projected laterally, sometimes with a round basal projection, upper tine (eroded) 3 times longer than lower one (basal tine not visible in other specimens, Fig. 34EView FIG).

Neurochaetae about 16 neurochaetae per bundle, blades bidentate, slightly shorter ventrally, 8 times as long as wide, with a small subdistal tooth, guard usually passing it ( Fig. 33DView FIG) (other specimens with blades 3-7 as long as wide, Fig. 34DView FIG).

Pygidium with integument smooth; anus projected as a short, distally expanded cylinder ( Fig. 33EView FIG); about 8 short, digitate anal papillae.

Pharynx not exposed. Oocytes not seen.

Pigmentation

Body with longitudinal, dorsal, irregular, discontinuous thin dark green or pale brown bands ( Fig. 34AView FIG), restricted to first 2-3 anterior chaetigers, alternating with small, round spots, and completely replaced by them in medial and posterior chaetigers, expanded into lateral cushions, but not into pygidium.Tentacular and dorsal cirri colorless; cirrophores pale in anterior chaetigers, yellowish in posterior ones; chaetal lobes pale. Prostomium with thin irregular marginal lines. Longitudinal bands progressively thinner ( Fig. 34BView FIG); all chaetigers with an irregular middorsal spot, irregularly ovoid, as long as wide, along chaetigers 1-6, becoming as long as wide in following chaetigers, connected by a thin, darker middorsal line continued to the last achaetous segment. This thin middorsal line bordered by paler areas, short in anterior and medial segments, becoming longer, running throughout all dorsal segmental surface in posterior segments. Pigmentation remaining visible after 8 years in ethanol ( Fig. 34CView FIG).

REMARKS

Hesione panamena Chamberlin, 1919  , reinstated, resembles H. pantherina Risso, 1826  in the key below. Their main difference is the type of acicular lobe. In H. panamena  acicular lobes are long, tapered, whereas in H. pantherina  they can be short or long but their tips are blunt to distally swollen. Living specimens also differ because in H. panamena  there are middorsal blackish, round spots whereas in H. pantherina  there are middorsal pale areas.

Hesione panamena  was originally spelled as such for the description ( Chamberlin 1919: 188) and H. panamica  for the legends to figures, and although both epithets are correct, the former has been followed by subsequent authors. Chamberlin (1919: 189) indicated that antennae were broken off, but they are present in the type, although because their bases are not exposed, they are difficult to observe. The details of the neurochaetal blades, as indicated in the original illustrations (his plate 22, figures 9-10) are accurate by showing long blades, with a small subdistal tooth, and its guard usually passing subapical tooth.

Hesione panamena  resembles H. intertexta Grube, 1878  by the small size of the eyes and antennae, and they also have similar neurochaetal blades. However, in H. panamena  the blade length/width proportions are smaller and the antennae are ovoid, whereas in H. intertexta  there is a wider variation in blade size, and antennae are tapered. Further, although pigmentation fades quite soon in ethanol, their patterns show some differences; in H. panamena  , segmental longitudinal lines are discontinuous whereas they are continuous in H. intertexta  , and in H. panamena  , there is a blackish, as long as wide middorsal spot just before a paler area, and this is not so evident in H. intertexta  . Further, in H. intertexta  acicular lobe is single, without any lower one, whereas in H. panamena  there can be a smaller, rounded lower tine.

Fauvel (1941: 9) recorded two Hesione  species for the Gulf of California: H. pantherina Risso, 1826  (this record is herein regarded as belonging to H. panamena  ), and H. genetta Grube, 1867  because of its pigmentation pattern: “à la face dorsale des traces de mouchetures brunes, ovales, alternées, qui rappellent la robe de la Genette.” (Transl.: on the dorsal surface there are remains of brown oval, alternating spots, resembling the genette skin). This specimen was found in the Paris museum, it differs from H. hartmanae  n. sp. described above, and initially regarded as having potential affinities because acicular lobes are double in H. genetta  and H. hartmanae  n. sp., but the Paris specimen has acicular lobes single. Fauvel’s specimen had been in ethanol for about 50 years before he saw it, and he referred to a pigmentation pattern, but after other half a century spent before I studied the specimen, this pigmentation is now completely faded out. This specimen is also regarded as conspecific with H. panamena  .

Monro (1926: 312) made a comparison of the size of guards and separated Hesione  species into three groups; among those having guards approaching the apical tooth he listed H intertexta  , H. reticulata von Marenzeller, 1879  , H. praetexta Ehlers, 1885  and H. panamena Chamberlin, 1919  . Further, in the previous page, Monro rejected, following Fauvel (1923a), the use of pigmentation pattern and the development of acicular lobes. As a consequence, in two of his publications on Panamian polychaetes ( Monro 1928: 79; 1933: 26) he regarded H. panamena  as a junior synonym of H. intertexta  , and recorded it for the Pacific coast of Panama. Hartman (1940: 212) followed this synonymy and listed specimens from Western Mexico to the Galápagos Islands, but her material includes two species: one with a very long upper acicular lobe, herein retained as H. panamena  , and another one with two acicular lobes, which were illustrated, and were based on Galápagos specimens, which are regarded as belonging to an undescribed species and described above as H. hartmanae  n. sp. The record of Hesione pantherina Risso, 1826  for the Gulf of California ( Fauvel 1941: 9) is regarded as belonging to H. panamena  . Consequently, there are two species in the Galapagos ( Blake 1991: 78) but their names should be changed to H. panamena  and H. hartmanae  n. sp. (see above).
