Orellana castaneamaculata Sanborn , sp. nov.
( Figure 1 View Figure 1 )
Holotype. male ( Figure 1A View Figure 1 ), “Valparaiso (2500 ft.)/Dept. Magdalena,/ Colombia, S.A. //Jan. //Carn. Mus. Acc. 1999” ( CMNH).
Paratypes. same data as holotype, female ( Figure 1 View Figure 1 ) ( CMNH), male ( AFSC) .
The name “Valparaiso” is found associated with 18 places in Colombia on the USGS Geonames site (http://geonames.usgs.gov/foreign/index.html). None of these localities are within the current Department of Magdalena and the collection year is unknown so it is impossible to determine if there has been a reorganization of Departments since the specimens were collected. As a result, the exact collection locality is unclear .
The species is named for the single castaneous spot on the proximal clavus of the tegmina.
Measurements of types (mm)
N is two males or one female, mean (range). Length of body: male 37.05 (36.5–37.6), female 37.0; length of tegmina: male 46.85 (46.4–47.3), female 51.9; width of tegmina: male 14.7 (14.3–15.1), female 15.5; length of head: male 4.7 (4.6–4.8), female 4.9; width of head including eyes: male 10.4 (10.3–10.5), female 11.3; width of pronotum including suprahumeral plates: male 16.55 (16.4–16.7), female 18.5; width of mesonotum: male 11.55 (11.5–11.6), female 12.6.
The lack of wing infuscation quickly separates O. castaneamaculata from the currently known species of Orellana , which have forewings that are nearly opaque or with numerous spots. The three tarsomeres differentiate O. castaneamaculata sp. nov. from Z. luculenta Distant, 1883 and Z. medialinea Sanborn, 2004 which also lack heavily infuscated wings. The Venezuelan Zammaralna bleuzini Boulard and Sueur also possesses three-segmented tarsi but the distal half of the forewing is opaque.

Additional small fuscous spot posterior to mark in anterior cranial depression, which also extends anteriorly to epicranial suture anterior arm and has a curved lateral extension just anterior to lateral ocellus in paratypes. Light fuscous mark on lorum at junction of lorum, gena and postclypeus, very dark in female paratype.

Mark continues half the remaining distance to head in ambient fissure in female paratype and connects to anterior lateral fissure in male paratype. Fuscous mark in anterior three-quarters of paramedian fissure with posterior extension onto disc from the middle of paramedian fissure to level of posterior lateral fissure terminus, curving laterally in female paratype. Triangular fuscous mark on either side of anterior midline connecting on anterior margin behind epicranial suture. Triangular mark reduced to two small anterior spots in female paratype. Triangular marks extend on either side of midline as parallel lines terminating at level of posterior paramedian fissure. Two small fuscous spots in ambient fissure on either side of midline. Small fuscous spots on pronotum between fissures in male paratype. Fine golden pile on pronotum, denser in fissures. Mesonotum castaneous with fuscous anterior and lateral submedian sigilla.

Entire male paratype operculum castaneous with fuscous spot at lateral base. Medial margins rounded, separated along midline. Short silvery pile and white pubescence on surface, denser at base and posteriolaterally. Sparse long silvery pile extending from ventral surface and margin.
