(Figure 1)
Type material
Holotype. male (Figure 1A), “Valparaiso (2500 ft.)/Dept. Magdalena,/ Colombia, S.A. //Jan. //Carn. Mus. Acc. 1999” (CMNH).
Paratypes. same data as holotype, female (Figure 1) (CMNH), male (AFSC).
Type locality
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.
Etymology
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.
Diagnosis
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.
Description
Coloration (Figure 1A). Ground colour of head and thorax castaneous, marked with fuscous, abdomen ferruginous and castaneous.
Head (Figure 1B). Castaneous, not as wide as mesonotum. Ring around each ocellus, linear marks within epicranial suture and angled mark in anterior cranial depression lateral to lateral ocelli, spot between medial angle of eye and posterior head, and small spot on either side of midline on frontoclypeal suture fuscous. 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. Postclypeus castaneous, darker along midline medially and posteriorly on ventral surface in holotype and male paratype, dorsal side and transverse grooves fuscous. Anteclypeus castaneous, slightly darker laterally in holotype and male paratype. Rostrum tawny, labium castaneous medially with piceous tip reaching to abdominal sternite I. Scape castaneous, remaining antennal segments fuscous. Dorsal head and lateral postclypeus covered with fine golden pile. Long golden pile on ventral head, long silvery pile posterior to eye.
Thorax (Figure 1B). Lateral margin of pronotal collar expanded, lateral margin edged in fuscous. Fuscous mark within lateral fissure extending to ambient fissure, following ambient fissure laterally to level of widest pronotal collar expansion. 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. Medial submedian sigilla and lateral sigilla ferruginous. Lateral sigilla mark reduced to posterior spot in female paratype. Scutal depression fuscous. Fuscous spot on midline of disc between scutal depression and submedian sigilla. Transverse linear mark on posterior mesonotum anterior to lateral cruciform elevation. Cruciform elevation slightly darker medially. Metanotum tawny with castaneous spot anteriorly. Long silvery pile between anterior arms of cruciform elevation, along posterior mesonotum and on metanotum. Shorter, denser silvery pile on lateral mesonotum. Ventral pronotal collar extension fuscous. Anepisternum 2, episternum 2, basisternum 2 and basisternum 3 castaneous, all other ventral thoracic plates tawny. Basisternum 2 and basisternum 3 marked with fuscous posteriorly. Ventral segments covered with silvery pile and white pubescence.
Legs. Coxae, trochanters and femora striped with fuscous medially, castaneous centrally and tawny laterally. Fore femora with oblique primary spine, upright secondary spine and small curved distal spine. Tibiae castaneous, fuscous distally. Tarsi three-segmented, fuscous. Pretarsal claws castaneous with fuscous tips. Tibial spurs and tibial comb castaneous at base, fuscous distally. Legs tawny marked with fuscous in female paratype.
Tegmina and wings (Figure 1A). Hyaline. Tegmina with eight apical cells. Venation castaneous except ferruginous radius and subcostal vein. Basal cell castaneous. Small castaneous spot on proximal clavus. Wing base with fuscous marks. Basal membrane light blue. Wings hyaline with six apical cells. Venation castaneous. Light blue plaga, proximal costal cell, proximal radial cell, and anal cells 2 and 3 along anal vein 3. Proximal anal cells 1 and 2 and cubital cell along cubitus posterior vein light blue, becoming grey distally. Fuscous marks at base of wings.
Abdomen (Figure 1A). Tergites ferruginous except castaneous dorsolateral tergites 4– 6 connected by lighter area across posterior tergites. Hind margins of tergites 3–6 greenish blue, wider in male paratype, absent in female paratype. Lateral tergite 1, anterior medial margin of tergite 2, spots on lateral tergites 3–6 and anterior tergites 7 and 8 fuscous. Timbal cover castaneous, rounded anteriorly, incomplete exposing timbal dorsally and ventrally (Figure 1C). Medial margin folded laterally. Timbal greyish-white with three long castaneous ribs, a short rib between the anterior pair and a large, oblong castaneous spot between the posterior pair. Tergites covered with silvery pile, most dense on lateral timbal cover. Female tergites castaneous with lateral fuscous spots on tergites 3–6 covered in dense silvery pile. Sternites castaneous. Medial ferruginous spot on sternite III. Transverse fuscous line on anterior sternite II of male paratype. Small fuscous marks medially on posterior sternite I and hind margin of sternite VII.

Operculum. Male operculum dark tawny, semicircular not reaching to sternite I (Figure 1D). Castaneous at base, fuscous spot laterally at base. 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. Meracanthus castaneous with tawny lateral margin. Female operculum smaller, semicircular with similar coloration to male (Figure 1E).
