Mariaplax Rahayu & Ng 2014
Mariaplax Rahayu & Ng, 2014 Mariaplax Rahayu & Ng, 2014: 423. Remarks. The genus Mariaplax Rahayu & Ng, 2014 is characterized mainly by the broad third maxillipeds, with its mesial margin of the ischium straight, oblique or slightly rounded, the presence of a distinct longitudinal median groove on the lateral surface of all or some of ambulatory legs, and the curved, S-shaped, more or less twisted male G1. Mariaplax is the richest genus in the family Hexapodidae, with 14 described species thus far, all found in the Indo-West Pacific.Published as part of Rahayu, Dwi Listyo & Widyastuti, Ernawati, 2018, Additions to the Indonesian crab fauna of the genus Mariaplax Rahayu & Ng, 2014, and notes on Hexapus timika Rahayu & Ng, 2014 (Crustacea, Decapoda, Brachyura, Hexapodidae), pp. 231-246 in Zootaxa 4379 (2) on page 234, DOI: 10.11646/zootaxa.4379.2.5, http://zenodo.org/record/117546

Paguristes macrops Rahayu & Forest 2009
Paguristes macrops Rahayu & Forest, 2009 (Fig. 1E) Paguristes macrops Rahayu & Forest, 2009: 1317, figs. 3, 4. Material examined. 1 male 3.5 mm, Stn. Dredge 23, 26°16.380ʹN, 126°51.50ʹE, 12 November 2009, 125 m (RUMF-ZC-1648); 2 females, 1.0 mm, 2.5 mm, Stn. Dredge 79, 26°14.686ʹN, 126°49.623ʹE, 20 November 2009, 141– 165m (NTOUA01223). Remarks. Paguristes macrops is characterized by having rounded red spot on each of the mesial and lateral faces of the meri of the chelipeds and second and third pereopods. This character is also seen in P. gonagrus (H. Milne Edwards, 1836), Paguristes balanophylus Alcock, 1905, Paguristes alcocki McLaughlin & Rahayu, 2005, Paguristes lewinsohni McLaughlin & Rahayu, 2005, Paguristes aulacis Rahayu & Forest, 2009, and Paguristes ocellus Komai, 2010, but there are morphological and other colour differences among these species. The specimens in the present study agree well with the original description and the colouration of Paguristes macrops, but minor differences are noted: the ocular peduncles that are shorter than the shield, and the mesial face of the dactyl of each cheliped has only one longitudinal row of tubercles. The specimens collected (2.54, 3.45 mm in shield length) are smaller than the specimens examined by Rahayu & Forest (2009, 3.0– 9.1 mm in shield length), and too limited to evaluate whether these differences are only intraspecific variations or they warrant the separation of species. Distribution. The Philippines and now recorded from Kume Island, Japan; 83– 165 m.Published as part of Rahayu, Dwi Listyo & Osawa, Masayuki, 2012, Hermit crabs (Crustacea: Decapoda: Diogenidae) from the KUMEJIMA 2009 Expedition, Japan *, pp. 176-190 in Zootaxa 3367 (1) on page 185, DOI: 10.11646/zootaxa.3367.1.17, http://zenodo.org/record/525207

Indonesia: 2 males (15.8 × 11.0 mm, 10.0 × 6.8 mm), 3 females (14.7 × 10.4mm, 16.7 × 11.8 mm, 13.4 × 9.5 mm) (NNM-ZMA Crust De 240130), 1 male (NNM Crust D 2180), station 12, 7° 15 'S 115 ° 15.6 ’E, north of Bali, 289 m, coll.

Webber, Siboga Expedition, 1899. Remarks. On the basis of the description and location, Rahayu & Ng (2014) indicated that Tesch’s (1918) records of “ Hexaplax megalops Doflein, 1904 ” from Indonesia probably belonged to their new species, Hexaplax aurantium. Re-examination of these specimens confirms this.Published as part of Ng, Peter K.

Singapore, Indonesia; intertidal and subtidal to 21 m, on mud flat, and sandy, gravel substrates. Remarks. Rahayu (2015) gave a short diagnosis and a description of the colouration in life on the basis of the material from Johor Strait. The specimens examined in this study are smaller than those examined by Rahayu (2015), however because of the following specific characters, the identification is justified: the possession of a long antennal acicle that is overreaching the base of the fourth antennal peduncular segment; the relatively small corneas; the convex outer surface of the palm of the left cheliped that is covered with spinulose tubercles and with a strong median ridge; and the presence of a longitudinal brown stripe on the dorsal surface of the ocular peduncle.Published as part of Rahayu, Dwi Listyo, 2022, Hermit crabs of Singapore (Crustacea: Decapoda: Anomura: Diogenidae, Paguridae), with description of two new species, pp. 329-363 in Raffles Bulletin of Zoology 70 on page 345, DOI: 10.26107/RBZ-2022-0017, http://zenodo.org/record/717464
