Fused but not prominent; tip of penes composed with 3 papillae.</p><p>Etymology. The scientific name excavata is derived from the Latin meaning “hollow”, referring to be deeply concaved on dorsal sulcus.</p><p>Remarks. Although gnathiid morphology quite differs between male adult, female adult, and larva, the taxonomy has traditionally been based on the male morphology only. Congeners of the adult males are distinguished by the frontal border, pleotelson, pylopod, maxilliped, and their combinations. In addition to these, number of setae on the mouthparts, the presence of tubercles and setae on cephalothorax and appendix masculina on pleopod II are also frequently used.</p><p>Among the 190 species of the family Gnathiidae, Gnathia and Caecognathia species comprise the most number of species of this family (containing approximately 110 and 50 species, respectively). These two genera are closely related and have been even synonymised with each other until Cohen &amp; Poore (1994) reviewed the classification of the Gnathiidae . Cohen &amp; Poore (1994) recognised 10 genera, including Gnathia and Caecognathia, in the family. According to their key, Gnathia species can be distinguished from the congeners by the presence of a frontal process on the frontal border of the cephalothorax (not deeply excavated frontal border), the presence of paraocular ornamentation, and depth and/or width of dorsal sulcus. On the other hand, Caecognathia species can be distinguished from the congeners by the absence of a frontal process on the frontal border (frontal border often rounded) (Cohen &amp; Poore 1994). However, the characters of the frontal “border” and the frontal “process” seem to be ambiguously interpreted by the authors. Some Gnathia species have large, rounded frontal “process” (or anteriorly pronounced frontal borders); e.g. G. triobata Schultz, 1966; G. prolasius Cohen &amp; Poore, 1994; G. ubatuba Pires, 1996; G. r i c a rd o i Pires, 1996. However, these characters has been termed differently by different workers, e.g. “large frontal process” (Cohen &amp; Poore 1994), “frontal projection” (Schultz 1966) or not even noted (Pires 1996). Furthermore, the frontal borders of Caecognathia species are indeed pronounced anteriorly; e.g. C. hirusta (Schultz, 1966); C. bicolor (Hansen, 1916) (redescribed by Svavarsson 1999); C. dolichoderus Cohen &amp; Poore, 1994 . Future study may provide a better understanding on the systematic position of the genera.</p><p>Gnathia excavata n. sp. is most similar to G. notostigma Cohen &amp; Poore, 1994, because of the following characters; the mediofrontal process is broad with bifid apex and the whole body is not covered with tubercles (Cohen &amp; Poore 1994). However, G. n o t o s t i g m a has very pronounced paraocular ornamentation forming slight mesolateral ridge (Cohen &amp; Poore 1994) rather than three small indistinct tubercles of the present new species.</p></div>	https://treatment.plazi.org/id/DB1B87CDF36BFFAAFF38FF2E0970FBEE	Public Domain	No known copyright restrictions apply.
