Body generally unpigmented with few small spots on anterolateral margins of pereomeres, body elongated, all segments clearly segmented dorsally, ventrally and laterally; head suboval, distinct from first pereomere; approximately 1.7-times as wide as long; anterolateral borders rounded, head approximately 70% as wide as first pereomere; eyes present mediolaterally; antennule of three articles, antenna of seven articles, both distally setose (Figure 3C–D).

Pleon with five segments plus pleotelson. Pleomeres progressively narrower posteriorly, distinctly separated, tips rounded; globose uniramous pleopods on pleomeres 1–5 near midline (Figure 3B, H–I); pleotelson produced in two tapered lateral lobes and prominent medial anal cone, small tuft of setae on distolateral tips of projections; uropods absent (Figure 3J).</p> <p>Etymology</p> <p>This specific name refers to the lack of dramatic asymmetry in females of this species that is, except in A. foresti, otherwise characteristic of the species in the genus.</p> <p>Remarks</p> <p>Markham (2003) listed seven genera of branchial parasitic bopyrids from hermit crab species (Diogenidae, Paguridae and Parapaguridae), but currently there are eight including Bopyrophryxus Codreanu, 1965 (Bourdon and Boyko 2005). In only one of these eight genera are the propodi of the female’s pereopods modified into “sockets” for insertion of the dactyli, and so we must assign this new species to Asymmetrione. The near total lack of asymmetry of the female reported here does not in itself preclude inclusion of the species in Asymmetrione. In fact, the genus Megachelione Bourdon, 1968, with sole species M. foresti Bourdon, 1968, was synonymized with Asymmetrione by Markham (1975) after determination that the only character separating these two genera was the degree of asymmetry of the females. In all respects, including the limited asymmetry, the new species described here resembles A. foresti. It can be separated from A. foresti by the shape of the female head (ovate in A. foresti vs. distinctly wider than long in A. aequalis), development of the female pereon coxal plates (well developed on pereomeres 1–4 with incomplete plates on 5 and 6 in A. foresti vs. pereomeres 1–4 only in A. aequalis), and female pleomere lateral plates (well developed on pleomeres 1–5 in A. foresti vs. lacking in A. aequalis), as well as the size of the anal cone in males (subequal to pleotelson posterolateral projections in A. foresti vs. much shorter than pleotelson posterolateral projections in A. aequalis). Although Markham (1975) stated that A. desultor Markham, 1975, was similar to A. foresti, the present species is much more so. A key is given below to facilitate the separation of the females of the 10 species of Asymmetrione now known. In many cases, the males are either not described in enough detail or lack obvious characters to separate them easily, although some species (e.g., A. clibanarii) are quite distinct from others. Although the males can be difficult to separate, their uniformity in almost all characters (except for the number of antennal segments and pleotelson/uropod or posterolateral projection ratios) supports the inclusion of all 10 species in Asymmetrione, as does the shared character of the propodal “socket” in females.</p> <p>Key to females of Asymmetrione species</p> <p>1.

However, no overall pattern of the degree of host-specificity has ever been demonstrated for bopyrids (one species has been found on 13 different hosts, see Boyko and Williams (2009)) and, in fact, Muñoz and Olmos (2007) cited the same two hosts for Ione ovata without similar comments. Prevalence was 10.8% on N. brachyophthalma (Muñoz 1997) and varies between 10% (n = 170) and 20% (n = unknown) on N. uncinata, being higher in juvenile size classes (Stuardo et al. 1986a).

Miranda-Vargas and Roccatagliata (2004) subsequently published a detailed redescription of both sexes based on several specimens collected from two different hosts from Argentinean Patagonia. Pseudione tuberculata parasitizes three lithodid hosts (see Table 1) from Patagonian austral waters. The prevalence of P. tuberculata in Paralomis granulosa can reach nearly 46% in hosts of carapace length of 10–19.9 mm, but this rate steeply declines as host size increases (Roccatagliata and Lovrich 1999). Cañete et al. (2008) reported high prevalence (near 30%) of P. tuberculata from juveniles of Lithodes satolla in the Magellan region. Detrimental effects reported for P. granulosa include sterilization and reduction of growth (Roccatagliata and Lovrich 1999). High mortality is also suspected in small-sized crabs and evidence of former parasitization in larger hosts has been found (Roccatagliata and Lovrich 1999).</p> </div>	https://treatment.plazi.org/id/664D87EBFF915057FCC176499253FCBE	Public Domain	No known copyright restrictions apply.

The characters of the juvenile female specimen, particularly the pleotelson shape, appear similar to those seen on the female holotype of A. thompsoni (see earlier), while the pleotelson of the mature female resembles that of A. hyptius adult females. Previous records of A. hyptius cover a wide range of the North and South American Atlantic coasts, parasitizing several species of Pagurus and Iridopagurus (Boyko and Williams 2003) from Massachusetts, USA to Curaçao, and a similar, perhaps identical, species was collected in the Beagle Channel (Argentina) as the south- ernmost locality recorded for any member of the genus (Diaz and Roccatagliata 2006). If the present material proves to be identical with the true A. hyptius, this would constitute the first record in Pacific waters, as well as a new host record. If the Chilean material is distinct from A. hyptius, it may represent A. thompsoni (see earlier) that was described from a possibly juvenile female and adult male, and would provide the first host identification for this species. It is also possible that the Chilean and Argentinean Anathelges material are conspecific but distinct from the northern Atlantic specimens of A. hyptius. As the Chilean specimens are lost, more collection must be done along with detailed comparison of northern Atlantic material, Argentinean, and Chilean specimens. Prevalence of A. cf. hyptius in P. villosus was much lower 0.07% (n = 2751) than even the low numbers recorded from Pagurus comptus White, 1847, from Patagonian waters (0.5%, n = 3143) (Diaz and Roccatagliata 2006).</p> </div>	https://treatment.plazi.org/id/664D87EBFF975052FCC5739C9565FDAE	Public Domain	No known copyright restrictions apply.
