Gamasellodes lavafesii Castro, Azevedo &amp; Castilho sp. nov. is most similar to Gamasellodes magniventris Mineiro, Lindquist &amp; Moraes, 2009, but females of the latter have posterior margin of genital shield truncate; ventrianal shield broader, incorporating the pair of platelets between genital and ventrianal shields, with anterior margin nearly straight and less densely punctate; setae Jv 1, Zv 1 and Zv 2 in nearly transverse alignment; with a single pair of ellipsoidal metapodal platelets; and Jv 3 in about transverse line with Jv 2. The new species also differs from the similar Gamasellodes novibicolor Ma, 2005 by the different ornamentation of the dorsal idiosomal shield and by having setae r 4 and r 5, and from Gamasellodes plaire Halliday, Walter &amp; Linsquist, 1998 by the different ornamentation of the dorsal idiosomal shields and the straight posterior margin of the genital shield and anterior margin of the ventrianal shield in the latter.</p><p>The marginal strip on the dorsal shield of the new species here described is also depicted in the descriptions of some species of Gamasellodes (Moraes et al. 2016), namely Gamasellodes andinus Rueda-Ramirez, Varela &amp; Moraes, 2016; Gamasellodes insignis (Hirschmann, 1962); Gamasellodes rectiventris Lindquist, 1971 and Gamasellodes vermivorax Walter, 1987 . Differences between these and the new species are mentioned in the key to the separation of the species of the genus.</p><p>The type localities of this species are quite distant from each other, about 2,000 km in straight line. These places are quite similar in relation to temperature (annual average of about 25ºC in Sinop and Olho d´Água das Flores), but quite different in relation to rainfall (annual total average of respectively about 2,550 and 640 mm) .</p></div>	https://treatment.plazi.org/id/F354F22DFFDCB51A2FCBF936FB1FF85B	Public Domain	No known copyright restrictions apply.

A revision of the Gamasellodes is considered highly desirable. The main objective of the present key is to help the separation of described species based on what is available in the literature. Care was taken to avoid taking into consideration characters that could be more easily overlooked, as absence of structures common for species of the genus, as summarised by Moraes et al. (2016).</p><p>Gamasellodes eusetosus (Karg, 2007) has some odd characteristics for a species of this genus, especially the relatively broad dorsal and ventral shield in relation to other species of the genus, the distinctly reticulate sternal and ventrianal shields, the close genital and ventrianal shields, the absence of differentiated presternal region and the insertion of S 4 and S 5 on small protuberances. This species was originally described in Leioseius Berlese, but in the key to ascid genera provided by Moraes et al. (2016), it keys out as a Gamasellodes, genus to which it was transferred in that publication. That species is also included in the subsequent key.</p><p>The original description of Gamasellodes bicolor (Berlese, 1918) is not sufficiently detailed. In the construction of the key, we based ourselves on the redescription provided by Bernhard (1963).</p><p>1.
