Type locality. Tolo Harbor , Hong Kong ( Markham, 1982) .
Distribution. Hainan, China ( An et al., 2011), Hong Kong ( Markham, 1982), Thailand ( Markham, 1985), South Korea ( Kim & Kwon, 1988), Singapore ( Markham, 2009), Australia: Queensland ( Markham, 2010), Philippines (herein), Taiwan (herein).
Hosts. Diogenidae : Calcinus gaimardii (herein), Calcinus morgani (herein), Clibanarius merguiensis ( Brunenmeister, 1980; Markham, 1985; herein), Clibanarius taeniatus (H. Milne Edwards, 1848) , Clibanarius virescens ( Krauss, 1843) ( Markham, 2010) , Diogenes aff. edwardsii (De Haan, 1849) ( Markham, 1982) , Diogenes pallescens Whitelegge, 1897 ( Markham, 2009) , Diogenes sp. (possibly aff. edwardsii ) ( Kim & Kwon, 1988), Diogenes tumidus (herein).
Size range (Length). Females: to 11.5 mm (herein), males: to 3.6 mm ( Markham, 1985).
Remarks. Pseudostegias dulcilacuum (Figs. 13, 14) and P. setoensis (Fig. 15) are similar, but can be distinguished by the following characters of the female: barbula a pair of smooth slender lobes lateral to a broad smooth ovate medial lobe in P. dulcilacuum (Fig. 13B) vs. multiple (3–4) highly digitate slender lobes (no medial lobe) in P. setoensis (Fig. 15B); pair of large hooked lobes on ventral surface of body under 5 th oostegites lacking in P. dulcilacuum vs. present in P. setoensis (Fig. 15C, see also An et al., 2011: Fig. 4B), both species have a field of digitate extensions in the region under the 5 th oostegites; 5 th pleomere with pair of globose lateral plates and tubular posterior extension in P. dulcilacuum (Fig. 13A, C) vs. pair of kidney-shaped lateral plates and no posterior extension in P. setoensis (Fig. 15A, D). The males of P. dulcilacuum (Figs. 13D, 14) and P. setoensis (Fig. 15E) are very similar, although the pleotelson shape is more clearly triangular and elongate with obvious lateral segmentation traces in P. dulcilacuum (Figs. 13D, 14A, F) vs. more rounded and with little to no segmentation traces laterally in P. setoensis (Fig. 15E).
Although Markham (1982) indicated that the holotype of P. dulcilacuum was deposited in the USNM, it was never received there and the whereabouts of the type specimen is unknown. Markham (2010) reported P. dulcilacuum and P. setoensis from Australia; however, although his figures 32 and 33 were correctly labeled as P. dulcilacuum , his figures 34 and 35 were incorrectly labeled as being P. setoensis because the material they are based on was listed by Markham (2010) under P. dulcilacuum and the figures match P. dulcilacuum in all details. Markham (2010) cited Clibanarius sp. as a host for P. dulcilacuum but Dunbar & Coates (2000) listed C. taeniatus and C. virescens , so the host “sp.” of Markham (2010) is actually C. taeniatus .
An et al. (2011) commented on the possible synonymy of P. dulcilacuum with P. setoensis but the present material does not support this conclusion. An et al.’s (2011) material was a mixture of P. dulcilacuum (Chinese mainland) and P. setoensis ( Hong Kong).
Examination of this large series of specimens from varied localities in different stages of development has resulted in the conclusion that Pseudostegias macdermotti Williams & Boyko, 1999 , described from Bali on C. gaimardii , is a junior synonym of P. dulcilacuum and was based (in part) on an immature female whose 5 th lateral plates were likewise immature and not yet fully separated. The host of the types of P. macdermotti was originally identified as C. gaimardii , but Rahayu & Forest (1999) showed that “ C. gaimardii ” was a species complex and described C. morgani as a new species. The host of P. macdermotti matches the shield coloration of C. morgani . Additional specimens of P. dulcilacuum were obtained from C. morgani in Taiwan (see Material Examined).
