description
Description. Measurements, mean (range) (n = 20). Male. Head: width 1.3 mm (1.2 - 1.4 mm). Pronotum: length 0.85 mm (0.7 - 1 mm), width 0.6 mm (0.4 - 0.8 mm). Forewing: length 11.7 mm (10 - 13.4 mm); 4 - 6 inner and 5 - 7 outer gradate veins. Hindwing: length 10.2 mm (8.8 - 11.6 mm); 3 - 5 inner and 4 - 6 outer gradate veins. Female (n = 11). Head: width 1.2 mm (1.1 - 1.3 mm). Pronotum: length 10 mm (0.9 - 1.1 mm), width 0.95 mm (0.9 - 1 mm). Forewing: length 12.4 mm (11.9 - 12.9 mm); 5 - 6 inner and 7 outer gradate veins. Hindwing: length 13.5 mm (10.2 - 11.9 mm); five or six inner and six or seven outer gradate veins. Head. Front mainly pale (rarely with one brown, irregular transverse-stripe), vertex, clypeus, labrum, gena, maxillary, and labial palpi pale (Fig. 1 C). Scape pale with lateral red stripe and pedicel pale with posterior-lateral red spot; flagellum pale, with 85 - 90 flagellomeres (n = 31). Thorax. Pronotum greenish with a discontinuous red lateral stripe on each side and a medial, longitudinal yellow band; meso- and metanota greenish, each with a medial, longitudinal yellow band and two anterior reddish-black spots (Fig. 1 A), and sometimes with two posterior red or orange spots; pleura pale green. Legs: pale green with yellow tarsi, except one or two dark-brown apical tarsomeres (Fig. 1 C). Forewings: venation mostly green, but some crossveins dark; dark markings at apex of 1 A, posterior cubitus, and Cua-Cup crossveins form a distinct chevron-shaped mark (Fig. 1 D); four to six inner and five to seven outer gradate veins. Hindwing: venation green, with apical section of radius dark; three to five inner and four to six outer gradate veins, all green. Abdomen. Green, with dorsal, longitudinal yellow band; tergites with orange to dark-brown lateral elongate marks at posterior margin (Fig. 1 D). Male apodeme slightly sclerotized and thin, without ventral lobe (Fig. 3 A). Male genitalia. Gonarcus thick with wide and elongate lateral plates (Fig. 3 C); entoprocessus elongate, with evenly tapering tips (Fig. 3 B); gonocornus lacking. Arcessus very long, narrow, straight, with downward curved apical point (Fig. 3 B). Gonosaccus basally with gonosetae (Fig. 3 A). Gonapsis elongate, extending from base of gonosaccus, slightly upturned, terminating internally in a smoothly rounded apex (Fig. 3 E), with sclerotized microteeth on dorsal side (Fig. 3 D); membranous sac between apices of gonapsis and sternite 9 with a field of well-developed gonocristae (Fig. 3 A). Female. Similar to holotype. Female genitalia. Female subgenitalia as wide as long, with rounded apex and narrow medial notch (Fig. 3 G); spermatheca well sclerotized, with vela broad basally and strongly arched apically; spermathecal duct slightly sinuous before entering oviduct; ventral impression conspicuous (Fig. 3 F).
diagnosis
Diagnosis. This species has marks on the pronotum (a discontinuous red lateral stripe) and on the meso- and metanota (two anterior reddish black spots on each) (Fig. 1 B) and on the abdominal tergites (orange to dark-brown lateral elongate marks) (Fig. 1 D); forewing has the posterior branches of the cubital vein swollen, darkened and edged with dark on the membrane; last tarsal segments are darkened (Fig. 1 A). The gonosaccus basally bears gonosetae (Fig. 3 A); the arcessus is very long, narrow, straight, with curved apical point (Fig. 3 B); the gonapsis is elongate, its basal section extends internally from the base of gonosaccus and is slightly upturned, terminating anteriorly in a smoothly rounded apex (Fig. 3 E), the distal section extends externally and terminates dorsally with microteeth (Fig. 3 D); a membranous sac between apices of gonapsis and sternite 9 bears a field of well-developed gonocristae (Fig. 3 A).
etymology
Etymology. This species is named after the Tacana Volcano, located in the state of Chiapas, Mexico, where the specimens were collected.
