Abstract

We provide a detailed description, including illustrations, of a new species of mysid belonging to the genus Idiomysis W. M. Tattersall, 1922 from Pulau Bum Bum, Sabah, Malaysia. The presence of two segments of antennal scale, a shorter endopod of uropod than the exopod and a pair of minute spines at the apex of the telson distinguishes Idiomysis bumbumiensis sp. nov. from all other species in the genus. The present species is the seventh member of the genus Idiomysis and it is the first described in Southeast Asia. It is also the third species of tribe Anisomysini discovered in Malaysian waters. We include an updated dichotomous key of all Idiomysis species.

Introduction

Mysids are considered as one of the most abundant and widely distributed crustaceans in the world, are known to inhabit all aquatic areas, but they are predominantly found in marine environments (Gan et al. 2010). Wittmann et al. (2014) established the tribe Anisomysini (former Mysini) for the first time, encompassing seven genera; Anisomysis Hansen, 1910; Carnegieomysis W. M. Tattersall, 1943; Halemysis Băcescu & Udrescu, 1984; Idiomysis W. M. Tattersall, 1922; Javanisomysis Băcescu, 1992, Mysidium Dana, 1852 and Paramesopodopsis Fenton, 1985. Today, six species of Idiomysis have been recorded from various locations. They include Idiomysis diadema Wittmann, 2016 from the coast of Dahab, Red Sea; Idiomysis inermis W. M. Tattersall, 1922 from Kilakarai, Gulf of Manaar, India; Idiomysis japonica Murano, 1978 from Nomo, Nagasaki, Japan; Idiomysis mozambicus Deprez, Wooldridge & Mees, 2001 from Nacala Bay, Mozambique, South Africa; Idiomysis robusta Connell, 2008 from the east coast of South Africa; and Idiomysis tsurnamali Băcescu, 1973 from Gulf of Elat, Red Sea. Some species (Idiomysis japonica, I. mozambica and I. robusta) are free-living by nature (Murano 1978; Deprez et al. 2001; Connell 2008), while some others (Idiomysis diadema, I. inermis and I. tsurnamali) associate with other organisms, such as sea anemones and sea urchins (Băcescu 1973; Greenwood and Hadley 1982; W. M. Tattersall 1922; Bhaduri and Crowther 2016; Wittmann 2016). Numerous species of mysids from the tribe Anisomysini have been discovered in Southeast Asian waters (Sawamoto 2014). To date, only two species, namely Anisomysis (Anisomysis) aikawai Ii, 1964 and A. (Paranisomysis) ohtsukai Murano, 1994, have been identified from Malaysian waters (Gan et al. 2010; Tan et al. 2014; Moriya 2016; Tan and Azman 2018) and there was no record of any mysid of the genus Idiomysis.

Pulau Bum Bum is situated in the Semporna District of southeast Sabah, an East Malaysian State. It is a constituent of the Sulu Sulawesi Marine Ecoregion (SSME) and Coral Triangle Initiative (CTI), making it one of the richest marine biodiversity territories in the world (Ho and Kassem 2009). The most recent discovery was the newly-described Cerapus bumbumiensis Nurshazwan, Ahmad-Zaki & Azman, 2020, collected from Pulau Bum Bum (Nurshazwan et al. 2020). Even though this location is well-known for its extraordinary marine life diversity, there is little information on reef-associated crustacean fauna, including mysids. The present study described and identified Idiomysis bumbumiensis sp. nov. as a new species from Pulau Bum Bum, Sabah, Malaysia.

Materials and methods

The specimens were collected using SCUBA diving equipment on a silty substrate near a large coral ledge of ND Divers House Reef, Pulau Bum Bum in Semporna, Sabah of East Malaysia (Fig. 1). Specimens were initially fixed with a 4% formaldehyde-seawater solution and subsequently preserved with 85% ethyl alcohol after sorting in the laboratory. The body length of the mysids was measured in the laboratory from the tip of the rostrum to the end of the telson, excluding apical spines. Appendages were dissected using a stereomicroscope (Olympus SZX9) and mounted on a temporary slide with a glycerol-ethanol mixed solution for illustrative purposes. An optical microscope (Olympus BX43), equipped with a camera lucida, visualised the images. They were then pencil-drawn and digitised in Adobe Illustrator CS6 following guidelines by Coleman (2003). The terminology used was according to Wittmann et al. (2014). All specimens were deposited in the Universiti Kebangsaan Malaysia Muzium Zoologi (UKMMZ), Bangi, Malaysia.

Colouration in freshly fixed specimens

(based on UKMMZ-1611, BL. 2.3 mm; UKMMZ-1612, BL. 3.2 mm; Fig. 2A, B). Zesty orange eyes. Antennal scale, carapace including thoracic and translucent abdominal somites with a combination of small orange, yellow and black patches.

Remarks

The present species is the seventh member of the genus Idiomysis, but it is the first species of this genus to be described in Southeast Asia. It is also the third species of the tribe Anisomysini found in Malaysian waters besides Anisomysis (Anisomysis) aikawai Ii, 1964 and A. (Paranisomysis) ohtsukai Murano, 1994 (Moriya 2016; Tan and Azman 2018). The genus Idiomysis can be easily classified into two groups, based on the antennal scale; (i) entire or (ii) 2 segments. Idiomysis inermis, I. mozambica, I. robusta and I. tsurnamali are in the group of an entire antennal scale, while I. diadema and I. japonica are in the group of two-segmented antennal scale. The presence of the spine, which is exclusively in I. robusta, distinguishes the group with the entire antennal scale. The present new species, Idiomysis bumbumiensis sp. nov., has two antennal scale segments, similar to I. diadema and I. japonica. However, they can be differentiated by observing the apex of the telson. Both I. diadema and I. bumbumiensis sp. nov have a pair of minute apical spines exclusive to these two species; on the other hand, I. japonica has a bluntly rounded telson apex. The endopodal uropod in I. diadema shows a clear extension beyond the exopod, but this structure is shorter than the exopod in I. bumbumiensis.

Discussion

Idiomysis bumbumiensis sp. nov. is the sole representative of this genus in Southeast Asian waters. Idiomysis bumbumiensis sp. nov. was relatively abundant and easily found in the shallow water of lower than 15 m during night-sampling sessions (28 November 2018 and 29 November 2018). As they were directly collected using SCUBA diving equipment, supplementary information on their natural habitat and body colour is available. The recently described Cerapus bumbumiensis Nurshazwan, Ahmad-Zaki & Azman, 2020 was also observed in the accompanying fauna. Although one species of Idiomysis was categorically described in this paper, fellow macro-photographers discovered further evidence of at least two other distinctive species of Idiomysis in the vicinity.

Idiomysis lives either in a symbiotic relationship (Idiomysis diadema, I. inermis and I. tsurnamali) or free-living (I. japonica, I. mozambica and I. robusta). Idiomysis bumbumiensis is a free-living mysid that was found swimming in a swarm on the silty substrate. By comparing the body lengths of all the species of the genus Idiomysis, this new species is one of the smallest species, besides I. diadema. Another feature that distinguishes species within the genus Idiomysis is the length ratio between the telson and the last abdominal somite. As this feature has not been described for the six known species, the ratios are calculated, based on the original-drawn figures describing each species. The ratio is mostly 0.8–1.0, except for I. mozambicus, which has a ratio of 0.4. The ratio of the present species is 0.8. Thus, the telson of most Idiomysis species is estimated to be more than 4/5 times as long as the last abdominal somite, while I. mozambicus is 2/5 times as long as the last somite. As shown in Table 1, I. bumbumiensis sp. nov. can be distinguished from I. inermis and I. tsurnamali by several morphological features: two segments of antennal scale and a pair of minute spines on the apex of the telson. Table 1 shows a brief morphological variation from each species of the genus Idiomysis. More research would be required to uncover more underwater macrolife, particularly in this area known as the heart of the Coral Triangle. More unique and unidentified marine life would undoubtedly be discovered with the overwhelming support of local underwater photographers.
