( Fig. 7 )

TYPE MATERIAL. “ BOLIVIA: Santa Cruz, 3.7 km / SSE Buena Vista, Hotel Flora / & Fauna , 430 m; 5–15–XI–2001 / coll. M.C. Thomas & B. Dozier / tropical transition forest, BLT” male (FSCA). Paratypes. Same data as holotype, one female ( AFSC); “ BOLIVIA: Santa Cruz / 3.7 km SSE Buena Vista / Hotel Flora & Fauna / 17º 29.949’ S, 63º 33.152’ W // 406 m elev., blacklight trap /Tropical transition forest, 5–15–XI–2001 / M.C. Thomas & B.K. Dozier ” one female (FSCA).

REMARKS. This is a small species. The distinct postcostal area of the fore wing and the 5 apical cells of the hind wings quickly distinguish it.

ETYMOLOGY. The name is a combination of santacruz– for the Bolivian Department of origin of the type series and –ensis (L. suffix denoting place).

Fore femora with proximal spine longest and most oblique, secondary spine only slightly angled with curved tip, slightly longer than tertiary spine, tertiary spine angled less than primary spine, shorter than secondary spine in length with greater curving tip, and curving apical spine about half the size of tertiary spine. Spines castaneous with piceous tips. Tibial spurs and comb castaneous with piceous tips.

Operculum. Male operculum ground color not covering tympanal cavity or reaching anterior margin of sternite II, smoothly curving mediad to level of medial meracanthus, medial margin rounded. Meracanthus ground color with castaneous lateral margin, curved mediad, not reaching anterior margin of medial operculum. Operculum with short silvery pile, radiating long golden pile from margin. Female operculum ground color angled lateral margin forming oblique angle to rounded posterior margin, pointed medioposterior angle, extending posteriorly to anterior of sternite II and medially to lateral meracanthus. Meracanthus ground color with castaneous lateral margin and apex, curved mediad, extending beyond posterior operculum to posterior of sternite II.

Abdomen. Male abdomen tergites ground color, female tergites 1–8 with castaneous marks on either side of midline with dorsal distance between them decreasing in posterior tergites, fusing anteriorly in tergites 4–8, tergites covered with silvery pile, long pile on lateral surfaces. Timbal cover absent, timbal transparent with six long ribs. Sternites and epipleurites ground color, female sternites 2–6 with transverse castaneous midline, male sternite VII with transverse posterior margin, male sternite VIII with arched notch posteriorly, sternites radiating long golden pile, white pubescence laterally in one paratype.

Genitalia. Pygofer ground color, dorsal beak inflated, triangular radiating golden pile. Upper pygofer lobe inflated, medial base meeting over claspers, extending as finger-like extension that extends laterad and curves mediad to meet along midline, with curved terminus radiating short golden pile. Pygofer basal lobe extended fusing to lateral upper pygofer lobe, radiating golden pile medially. Uncus lobes absent, anal styles ground color radiating golden pile. Claspers thin, castaneous, curved laterad. Aedeagus light castaneous with two elongated pseudoparameres and ochraceous terminal membrane.

Female gonocoxite IX ground color. Gonapophysis IX castaneous with piceous tip. Gonapophysis VII and X dark ground color. Ovipositor sheath extends well beyond dorsal beak. Long golden pile radiating from ovipositor sheath, ovipositor sheath covered with short golden pile.

MEASUREMENTS (MM). N = 1 male or 2 females, mean (range). Length of body: male 10.6, females 11.98 (11.6– 12.35); length of fore wing: male 14.35, females 14.25 (13.8–14.7); width of fore wing: male 5.05, females 5.20 (5.0–5.4); length of head: male 1.7, females 1.90 (1.9–1.9); width of head including eyes: male 3.4, females 3.45 (3.3–3.6); width of pronotum including suprahumeral plates: male 3.6, females 3.65 (3.6–3.7); width of mesonotum: male 3.1, females 3.15 (3.1–3.2).

DIAGNOSIS. Parnisa santacruzensis sp. n. can be separated from P. demittens ( Walker, 1858c) and P. proponens ( Walker, 1858c) by its smaller size (these species have body lengths greater than 15 mm). Parnisa lineaviridia Sanborn & Heath, 2014 has more extensive thoracic markings, slightly longer body (male 11.1–12.5 mm, female 14.4 mm), and shorter (male 11.6–13.6 mm, female 14.0 mm) and narrower (male 4.5–5.3 mm, female 4.9 mm) fore wings ( Sanborn & Heath 2014). The body markings and general body coloration differentiate the species from the unicolorous green P. viridis Sanborn & Heath, 2014 and the castaneous with transverse piceous abdominal markings in P. moneta ( Germar, 1830) . Parnisa designata ( Walker, 1858c) is castaneous with a red venter. Parnisa haemorrhagica Jacobi, 1904 is green with an orangish-reddish abdominal venter. Parnisa angularis Uhler, 1903 has a ridged abdomen and brown-banded tergites, and P. protracta Uhler, 1903 has a red abdomen. The new species is most similar in general appearance to P. fraudulenta ( Stål, 1862) but the longitudinal abdominal markings are wider, separated by a greater distance so are more dorsolateral than on either side of the midline, and the marks extend posteriorly to the posterior abdomen and found in P. fraudulenta ( Stål, 1862) .

DISTRIBUTION. The species is known only from the type series collected near Buena Vista, Bolivia.
