Type material. Holotype. “Est. Cacao, 1000–1400m, / Lado SO Vol. Cacao, / P.N.G., Prov. Guan. / COSTA RICA, Elfin / Rainforest 91, May 1991, / L-N-323300, 375700 // COSTA RICA INBIO / CRI 000 / 515915” 1 male ( MNCR).

Etymology. The name is in reference to the small body size (minimus L. least) of this species which is the smallest of known species of Procollina .

Description. Ground color greenish tawny marked with castaneous. Fresh or live specimens may be green.

Head: Head not as wide as mesonotum, piceous surrounding lateral ocelli and anterior half of median ocelli, piceous surrounded by castaneous, light castaneous transverse fascia extending from lateral ocelli to anterior of eye, posterior to eye castaneous, supra-antennal plate castaneous, right marking reduced to anterior margin of supra-antennal plate, and posterior cranial depression light castaneous. Medial vertex and frons covered with short piceous pile, and longer silvery pile posterior to eye. Ocelli rosaceous, eyes castaneous. Ventral head greenish tawny with castaneous spot on medial gena curving along suture with anterior lorum, castaneous mark on posterior lorum along suture with anteclypeus, transverse castaneous mark onto middle of lorum. White pubescence on lorum and gena, short black pile on gena between eye and postclypeus. Postclypeus green with light castaneous on lateral margin, castaneous fascia across apex expanding laterally to entire junction of supra-antennal plate, with seven transverse grooves, short silvery pile and white pubescence on lateral postclypeus. Anteclypeus green with white pubescence. Mentum and labium greenish-tawny with piceous tip reaching to abdominal sternite I with sparse short silvery pile, longer pile on tip. Scape green, remaining antennal segments castaneous.

Thorax: Dorsal thorax greenish tawny. Pronotum tawny with green anterior margin with laterally curved castaneous marks on disc extending from middle of paramedian towards terminal lateral fissure, across anterior disc between paramedian and lateral fissures, transverse mark across anterior midline, mark in lateral fissure extending around lateral disk in ambient fissure to join with mark extending from posterior lateral fissure, and castaneous spot on posterior ambient fissure on midline that extends across pronotal collar. Pronotal collar green except for castaneous spot on dorsal midline. Pronotum with sparse, short silvery pile, a small amount of black pile on left side of pronotal collar posterior to lateral disk. Mesonotum greenish tawny, light castaneous submedian sigillae, lateral sigillae with light castaneous fascia on lateral margin and in posterior, small triangular mark between anterior submedian and lateral sigillae, disc posterior to submedian sigillae and lateral sigillae castaneous, lanceolate castaneous mark on midline extending from posterior submedian sigillae to and scutal depressions, scutal depression castaneous. Cruciform elevation green, wing groove greenish tawny. Metanotum greenish tawny, with castaneous spot near anterolateral margin. Long, dense silvery pile on mesonotum, very dense on lateral margin giving the appearance of a silvery fascia, between arms of cruciform elevation, and in wing groove, shorter silvery pile on dorsolateral disc, black pile posterior to lateral sigillae and posterior to anterior arms of cruciform elevation, on posterior midline of cruciform elevation, posterior and anterolateral wing groove. Ventral thoracic segments greenish tawny with light castaneous spots on katepisternum 2 and posterolateral episternum 3, with white pubescence and long silvery pile.

Wings: Fore wings and hind wings hyaline with eight and six apical cells, respectively. Venation green mottled with tawny, may be green in fresh specimens, except piceous posterior margin of anal vein 2 + 3. Radial and radiomedial crossveins not parallel. Basal cell lightly clouded. Pterostigma present. Infuscation on distal wing veins, on proximal radius anterior 2 connecting across radial crossvein, on radiomedial crossvein, on median crossvein, on mediocubital crossvein, cubitus anterior 2, spot at node, on nodal line on median vein, and median vein 3 + 4, across arculus, and light infuscation on lateral wing margin. Basal membrane of fore wing dark gray. Venation of hind wing tawny except green radius anterior and median veins, becoming castaneous distally. Anal cell 3 and anal cell 2 along anal vein 3 dark gray mottled with red, anal cell 1 and 2 along anal vein 2 gray. Infuscation on basal apical cell 2 and light infuscation on apex of wing margin.

Legs: Coxae, trochanters and femorae green striped tibiae and tarsi tawny. Fore femora proximal spine, thin, elongate and adpressed against femur, secondary spine triangular, upright, apical spine small, angled distally, all spines green. Tarsi tawny with castaneous tip, tarsal claws tawny at base with dark castaneous tips, tibial spurs and comb tawny with castaneous tips.

Operculum: Male operculum with curved lateral margin, smoothly rounded posterolateral margin, curved posterior margin, reaching to anterior of sternite II, green with transverse castaneous mark across base, darker on medial and lateral margins, covered with white pubescence. Medial margin rounded, extending to middle of hind coxa. Meracanthus pointed, green with castaneous spot on base, not reaching to middle of operculum, with sparse white pubescence. Opercula with long silvery pile radiating from edge.

Abdomen: Abdomen greenish tawny with transverse light castaneous band across dorsal midline of tergites 3– 7, darker and larger on anterior tergite 8, covered with piceous pile in a V-shaped pattern beginning on dorsal tergite 1 terminating on lateral tergite 8 and on lateral tergites, black pile separated by silvery pile appearing as two chevrons across dorsal abdomen. Timbal cover recurved, greenish exposing timbal, short silvery pile radiating from timbal cover. Timbal with four long and one intercalary ribs, dark spot on timbal plate. Sternites and epipleurites tawny with transverse castaneous mark on anterior sternite II, castaneous spots on auditory capsule, Ushaped castaneous spot extending from anterior sternite III, and castaneous sternite VII, male sternites III–VII translucent, sternite VIII U-shaped radiating long silvery pile. Sternites and epipleurites with white pubescence. Spiracles white.

Genitalia: Male pygofer greenish tawny, light castaneous along dorsal midline including dorsal beak, covered with short silvery pile, with rounded distal shoulder curved medially, dorsal beak roughly semicircular. Pygofer basal lobe indistinct, pygofer upper lobes ochraceous, elongated and depressed centrally with medial bend at threequarters of its length, adpressed to pygofer with rounded terminus. Anal styles castaneous with tawny base, anal tube castaneous. Median uncus lobe tawny with castaneous spot at base and apex, approximately triangular, surrounded by lateral uncus lobes. Lateral uncus lobes tawny, wrapping around sides of median uncus lobe and meeting along midline posterior to median uncus lobe, recurved laterally forming a semicircle in lateral view with rounded terminus forming a curved notch on posterior midline, tawny basal lateral uncus lobes rounded forming a support around base of aedeagus, tip of support piceous. Aedeagus tubular, dark castaneous.

Female is unknown.

Measurements (mm). N = 1 male. Length of body: 15.9; length of fore wing: 23.2; width of fore wing: 7.2; length of head: 2.5; width of head including eyes: 4.8; width of pronotum including suprahumeral plates: 5.9; width of mesonotum: 4.9.

Diagnosis. This species is the smallest of the known species of Procollina . The small body size, very small proximal spine of the fore femur, radiomedial crossvein being highly angled with respect to the radial crossvein quickly distinguish this species from all other Procollina . Procollina parva is the most similar species but the head is wider than the mesonotum, the body size is larger, there is infuscation on the ambient veins of the fore wings forming an L-shape with the infuscation on the distal fore wing veins, and the bend in the lateral uncus lobes when viewed from the size are more angulate rather than having a smooth curve.

Distribution. The species is known only from the type specimen collected in Guanacaste Province, Costa Rica.
