In males, article six of gnathopod 1 is very broad. The palm is sinuous and lined with stout robust setae. Additionally, four thick robust setae cover the posterodistal end of the sixth article. The dactyl is strikingly short, extending to only half the length of the palm. Gnathopod 2 (males), the palm is lined with robust setae and the proximoposterior corner protuberant. All the above characteristics can be seen through a microscope without dissection. However, the easiest way to recognize both males and females of this species is to examine the morphology of the sixth article of pereopods 6 and 7 (as well as pereopod 5, though this article is variable). If the distal margins of the sixth article of these pereopods are transverse, the specimen can be identified as H. tortugae; these margins are lobed and lined with grasping robust setae. Another distinct characteristic of H. tortugae is the shape of the uropods. The outer ramus of uropod 1 is broad and spatulate and its inner ramus is completely bare. The inner ramus of uropod 2 lacks setae, and is distinctly lanceolate.</p> </div>	https://treatment.plazi.org/id/03C99202FF9EFFFF0CFF34E2E2F747C9	Public Domain	No known copyright restrictions apply.

This whiplike seta on the maxilliped can be seen in lateral view of the head without dissection (figs. 1B and 5B). In many of the male specimens examined the large second gnathopods were seen “reversed,” or upside down, reflecting an essentially prehensile condition. Males and females of H. lowryi can be identified by their strongly oblique anterodistal margin of pereopods 6 and 7. These anterior distal margins are covered by seven falcate, robust setae. The morphology of the uropods in H. lowryi is consistent among males and females: both rami are lanceolate and their posterior margins are armed with robust setae (figs. 6D and 6E). Another notable feature limited to males is the broadly convex palm of the gnathopod 1; the anterodistal corner is weakly produced and covered with fine scales. The dactyl length equals that of the palm. In male gnathopod 2 the palm exceeds the length of the dactyl and the proximoposterior corner lacks robust setate.</p> <p>When encountered together, adults of H. tortugae are generally much larger than H. lowryi. For example, males of H. tortugae are typically 7–8 mm and females are approximately 6–7 mm. Males of H. lowryi are smaller at about 4.5–5.0 mm in length, while females are typically around 4 mm. Although many of the aforementioned characteristics are useful in recognizing both species, the strong sexual dimorphism displayed in H. tortugae and H. lowryi limit several of these characteristics to the males. Females of H. lowryi do not possess the whiplike seta of the maxilliped and neither female Hyachelia species exhibit distinctive gnathopods. However, the diagnostic characters of the pereopods are observable in all adult specimens. Furthermore, the robust setae in the anterodistal corner of the pereopods are not fully developed in very small juveniles of H. tortugae, and their distal margin may appear oblique.</p> </div>	https://treatment.plazi.org/id/03C99202FF9EFFFD0C8E314AE2FB4403	Public Domain	No known copyright restrictions apply.
