(Fig. 7)
Type material. Holotype male. “ PANAMA: Cocle / Altos de Campana / mv + bl, 13 May 1996 / R. Turnbow ” (UGCA).
Etymology. The name is a combination of megalo- (Gr. large) and - opercula and is in reference to the large male opercula when compared to the opercula of other known species of the genus.
Remarks. One of the undetermined species of Wolda & Ramos (1992) may represent this new species. However, no locality data or diagnostic characteristics were provided for any of these species and I was unable to locate any specimens labeled as one of the undetermined of the species so that I was unable to determine if the new species is the same as one of the previously mentioned species.
Description. Ground color greenish testaceous. Green is probably much brighter in fresh specimens based on specimens of C. occidentis I have seen.
Head. Head as wide as mesonotum, testaceous with green longitudinal green fascia lateral to lateral ocelli, along medial margin of eye, on posterior epicranial suture and on frons anterior to median ocellus. Long silvery pile posterior to eye. Ocelli rosaceous, eyes tawny and fuscous. Ventral head testaceous, green mark on medial lorum beginning at about half length and continuing along lateral anteclypeus. Silvery pile on ventral head. Postclypeus testaceous with green lateral margin, ventral side flattened laterally and centrally with deep, thin carina, dorsal surface testaceous, slightly darker along midline and bifurcating around carina at apex, with green posterior margin. Postclypeus with seven transverse grooves restricted to the anterior half. Anteclypeus testacesous, covered with long silvery pile. Rostrum testaceous, becoming castaneous and piceous at tip with long silvery pile on tip, reaching to hind coxae. Scape and proximal pedicel testaceous, distal pedicel and antennal flagellae fuscous.
Thorax. Dorsal thorax testaceous with green in posterior paramedian fissure extending posteriorly across disk to posterior lateral fissure, lateral fissure extending posteriorly across disk and laterally along ambient fissure, short silvery pile in ambient fissure, pronotal collar testaceous. Mesonotum testaceous with green sigillae, wing groove and central cruciform elevation. Metanotum testaceous. Silvery pile on mesonotum laterally, between anterior arms of cruciform elevation, in wing groove, and on posterior metanotum. Ventral thoracic segments greenish testaceous, with sparse, long silvery pile.
Wings. Fore wings and hind wings hyaline with eight and five apical cells respectively. Venation green, becoming testaceous distally, posterior anal vein 2 + 3 with piceous posterior margin. Basal cell clear. Infuscation on distal end of apical cell 1 extending across ambient vein to wing margin apex. Basal membrane of fore wing light gray. Venation of hind wing greenish.
Legs. Legs testaceous striped with green, distal tibiae and distal tarsi castaneous, tarsal claws green proximally, piceous distally. Fore femora with four spines, all angled with green base and castaneous tip, spines become smaller distally, proximal and secondary spines parallel, tertiary and apical spines parallel at base and angled more than proximal and secondary spine, tertiary spine curved in distal half. Tibial spurs green proximally, castaneous distally, tibial comb castaneous.
Operculum. Male operculum with straight lateral margin, rounded posterolateral, posterior and medial margins, not meeting medially, reaching to anterior of sternite II barely covering tympanal cavity, testaceous with ochraceous base and lateral margin, covered with silvery pile, more dense at base. Meracanthus pointed, extending about half the length of the operculum, ochraceous with a testaceous base. Opercula with long silvery pile radiating from edge.
Abdomen. Abdominal tergites testaceous with green posterior margins and greenish anterior tergite 2 margin, covered with silvery pile, most dense on tergite 8. Timbal cover absent, timbal with greenish timbal plate and nine testaceous ribs, extending below wing base. Sternites testaceous with short silvery pile, sternites III–VI with bright red posterior third, sternite VII almost completely bright red, sternite VIII testaceous with red along midline. Epipleurites testaceous, reflexed strongly forming a channel on either side of sternites.
Genitalia. Male pygofer testaceous with green lateral surfaces, dorsal beak roughly triangular with rounded apex, covered with short silvery pile, longer and more dense at base of upper pygofer lobe and along length of basal pygofer lobe. Pygofer basal lobe extended and fused to pygofer, pygofer upper lobes testaceous, elongated with rounded terminus, angled medially and meeting above anal styles. Anal styles light fuscous, anal tube green. Median uncus lobe green, very short. Claspers green with lobate base, curved spine with castaneous tip extending from posterior. Aedeagus castaneous, tubular at base, flattening distally with white membrane.
Female is unknown.
Measurements (mm). N = 1 male. Length of body: 14.9; length of fore wing: 18.65; width of fore wing: 7.2; length of head: 1.8; width of head including eyes: 4.0; width of pronotum including suprahumeral plates: 3.9; width of mesonotum: 4.0.
Diagnosis. This is the larger of the two known species of Conibosa. The body is of normal proportions for its size (about 4 mm wide vs. 3 mm in C. occidentis) with a slightly protruding postclypeus when viewed from the dorsal side rather than the prominently extended postclypeus of C. occidentis. Fore wing width is about 7.2. mm in the new species and about 5.5. mm in C. occidentis. The posterior abdominal segments in males in C. occidentis are red and the male operculum is small, roughly rectangular and angled with respect to the midline exposing the tympanal cavity on all sides except at base. There are still three species of Conibosa that have been introduced in the literature without species identification or description (Sanborn 2013) so there are no data available for comparison to the new species.
Distribution. The species is known only from the type specimen collected in Coclé Province, Panama.
