Definition and diagnosis. Sister to all known Eutychide Godman, 1900 (type species Hesperia physcella Hewitson, 1866 ) in the genomic trees ( Fig. 143), this female was identified as a possible Tromba xanthura (Godman, 1901) (type locality Panama: Bugaba) due to superficial similarities. This new species keys (incompletely) to Eutychide paria (Plötz, 1882) (J.50.5) in Evans (1955) but differs from it and other relatives by females having paler brown to yellow submarginal areas on the ventral hindwing, gradually getting paler towards the outer margin, and lacking pale or hyaline spots, except a minute semi-hyaline spot in the forewing cell M 2 -CuA 1, otherwise brown with paler fringes on the hindwing and towards the tornus of the forewing, as E. paria but fringes have a stronger orange tint. This species is not cryptic and is identifiable by its phenotype. In DNA, a combination of the following base pairs is diagnostic in the

nuclear genome: aly536.107.1:C90A, aly536.107.1:C114T, aly536.107.1:T144C, aly5412.7.12:T78C, aly347.13.1:C108T, aly252.18.1:C631C (not A), aly383.4.5:G51G (not A), aly1139.56.27:G42G (not A), aly1139.56.27:C45C (not T), aly527.10.1:A51A (not G); and COI barcode: T46C, A67G, T202T, A214G, A325A, T421C, A607A.

Type material. Holotype: ♀ deposited in the collection of the California Academy of Sciences, San Francisco, CA, USA ( CAS), illustrated in Fig. 144, bears the following six rectangular labels (1 st handwritten, others printed with handwritten text shown in italics), five white: [ Costa Rica, Cariblanco | Prov. Cuesta Angel | 21 Mar 81, 800 m], [ Tromba | xanthura ? | (Godm.) | Det.C.D.Macneill '98], [Collection of | C.D.MacNeill], [DNA sample ID: | NVG-22109F02 | c/o Nick V. Grishin ], [{QR Code} CASENT | 8568789], and one red [HOLOTYPE ♀ | Eutychide | trombella Grishin].

Type locality. Costa Rica: Heredia Province, Cuesta Angel Forest Ravine near Cariblanco , elevation 800 m.

Etymology. The name is given for the phenotypic resemblance of this species with Tromba Evans, 1955 (type species Tromba tromba Evans, 1955 ) and is an adjective.

Distribution. Currently known only from the holotype collected in northeastern Costa Rica.
