Female holotype and paratype male (O.Sychra CR186) ex Turdus assimilis, COSTA RICA: Zona Protectora Las Tablas, La Amistad Lodge (8°54’N, 82°47’W; 1300 m), 21 August 2010, Sychra and Literak leg. Paratypes: 1 female and 1 male (O.Sychra CR187) with the same data as holotype, both deposited in INBio (O.Sychra CR186–187) and 1 female and 2 males with the same data as holotype, deposited in MMBC (O.Sychra CR188–189).</p><p>Remarks. Although Lindell et al. (2002) mentioned Myrsidea sp. from T. assimilis, this is the first species determination of a Myrsidea from this host. The female of M. assimilis sp. nov. is characterized by (1) the shape of tergites I–II (Fig. 1), (2) a wide median gap in rows of tergal setae on II–VIII (Fig. 1), and (3) a TW of at least 0.50. These characters place M. assimilis sp. nov. close to M. varia Ansari, 1956 (ex Turdus ignobilis debilis Hellmayr, 1902 from Peru), and M. abidae Ansari, 1956 (ex T. fumigatus aquilonalis (Cherrie, 1909) from Venezuela and the Republic of Guyana). However, the female of M. assimilis sp. nov. can easily be separated from that of M. varia by its smaller number of setae on tergite I (8–10 vs. 15) and larger number of setae on tergites IV–VII (in total 66–80 vs. 57), and from that of M. abidae by its smaller number of setae on sternites III–V (in total 93–98 vs. 109–120) and smaller dimensions, especially TW (0.50–0.51 vs. 0.54).</p><p>The male of M. assimilis sp. nov. differs from that of M. varia by its genital sac sclerite (compare Fig. 2 with fig. 73 in Clay 1966). Also, it is well characterized by the following additional features: (1) tergal chaetotaxy, and (2) sternites III–VII without anterior setae. These characters place the male of M. assimilis sp. nov. close to M. indigenella Ansari, 1956 (ex Turdus maranonicus Taczanowski, 1880 from Peru) and to M. abidae Ansari, 1956 . However, the male of M. assimilis sp. nov. can be distinguished from that of M. abidae by its smaller number of setae on tergite VI (14–16 vs. 18–22) and sternite III (22–23 vs. 25–28) and from that of M. indigenella by its smaller number of setae on tergite I (11–12 vs. 14) and sternite VIII (7 vs. 10), and by larger number of setae on tergite IV (19–21 vs. 17) and tergite VII (14–16 vs. 13).</p><p>Etymology. The species name is a noun in apposition derived from the specific name of the type host.</p></div>	https://treatment.plazi.org/id/03A0C4625159FFE30D8FFCEDFAE560F9	Public Domain	No known copyright restrictions apply.

It differs greatly from M. rohi — described by Ansari (1956) from the same host but at a different location in Costa Rica — by its reduced hypopharyngeal sclerites (Fig. 3). This character places M. cerrodelamuertensis sp. nov. close to M. sultanpurensis Ansari, 1951 from Myophonus caeruleus (Scopoli, 1786) from Pakistan and Afghanistan. However, both sexes of M. cerrodelamuertensis sp. can easily be distinguished from that species by: (1) absence of setae on sternite I, (2) presence of anterior setae on sternites IV–VII, and (3) smaller number of setae on metanotum (6–7 vs. 10–14). The male is also well-separated from those of other Myrsidea from the Turdidae by its unique genital sac sclerite (Fig. 5).</p><p>Etymology.

The female of M. hrabaki sp. nov. is characterized by the following: (1) Tergite I with straight posterior margin, (2) tergites II–III with slight medioposterior convexity (Fig. 7), (3) metanotum with only 6 setae, and (4) sternites III–VII not arched and without anterior setae (Fig. 7).</p><p>Although the male features of M. hrabaki sp. nov. agreee with the thoracica species group sensu Clay (1966), it differs by its genital sac sclerite (Fig. 8), which is of the same type as that of M. ishizawai Uchida, 1926 from Zoothera dauma (Latham, 1790) from Japan. Nevertheless, characters of M. hrabaki agreeing with the thoracica species group—i.e. (1) number of outer dorsolateral setae of first tibia under 10, and (2) post-spiracular seta III markedly shorter than II—distinguish the male of M. hrabaki sp. nov. from that of M. ishizawai .</p><p>Etymology.

Nevertheless, characters of M. obsoleti agreeing with the carrikeri species group sensu Clay (1966) — i.e. (1) pronotum with 8 posterior setae, and (2) tergite I of female with median anterior emargination — distinguish M. obsoleti sp. nov. from M. regius described by Ansari (1956) from the same host at a different location in Costa Rica and belonged to the thoracica species group, i.e. it has (1) pronotum with 6 posterior setae, and (2) tergite I of female without median anterior emargination.</p><p>The female of M. obsoleti sp. nov. is characterized by the following: (1) genital chamber without conspicuous comb-like projections of the inner surface (see fig. 24 in Clay 1966), (2) tergites II–III compressed by enlarged tergite I with convex posterior margins, (3) smaller number of tergal setae, and (4) sternite VI slightly arched. These characters place M. obsoleti sp. nov. very close to M. aitkeni Clay, 1966 from Turdus nudigenis nudigenis (Lafresnaye, 1848) from Trinidad. However, the female of M. obsoleti sp. nov. can be distinguished from that of M. aitkeni by having median gaps in the rows of tergal setae, larger number of anterior setae on sternite II (19–22 vs. 9–12) and on sternite VII (16–18 vs. 10–13). Except for presence of median gaps in the rows of tergal setae, the male of M. obsoleti sp. nov. appears to be indistinguishable from that of M. aitkeni .</p><p>Etymology.

These characters place M. quinchoi sp. nov. close to six species from thrushes of the genus Turdus ( M. abidae Ansari, 1956, M. assimilis sp. nov., M. indigenella Ansari, 1956, M. keniensis Clay, 1966, M. tapetapersi sp. nov. and M. regius Ansari, 1956).

Furthermore, our specimens from Cerro de la Muerte ( Tapanti NP) differ from those from Barva (Braulio Carrillo NP) as well as from those redescribed by Clay (1966) in the number of tergal setae and shape of tergites of the female. According to our knowledge of intraspecific variation in Myrsidea species (Clay, 1966), these differences could be used to separate these two populations into subspecies (see Palma &amp; Price 2010), or even into species. However our preliminary results from molecular analyses of partial sequences of the mitochondrial COI gene do not support genetic distinctiveness of these two samples. Until final results of molecular analyses become available we suggest to consider the Myrsidea population from the Catharus gracilirostris of Cerro de la Muerte as conspecific with M. rohi .</p><p>Descriptions of samples from separate localities.
