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. 1BView Figure 1) and on the abdominal tergites (orange to dark-brown lateral elongate marks) ( Fig. 1DView Figure 1); forewing has the posterior branches of the cubital vein swollen, darkened and edged with dark on the membrane; last tarsal segments are darkened ( Fig. 1AView Figure 1). The gonosaccus basally bears gonosetae ( Fig. 3AView Figure 3); the arcessus is very long, narrow, straight, with curved apical point ( Fig. 3BView Figure 3); 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. 3EView Figure 3), the distal section extends externally and terminates dorsally with microteeth ( Fig. 3DView Figure 3); a membranous sac between apices of gonapsis and sternite 9 bears a field of well-developed gonocristae ( Fig. 3AView Figure 3).

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. 1CView Figure 1). 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. 1AView Figure 1), 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. 1CView Figure 1). Forewings: venation mostly green, but some crossveins dark; dark markings at apex of 1A, posterior cubitus, and Cua-Cup crossveins form a distinct chevron-shaped mark ( Fig. 1DView Figure 1); 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. 1DView Figure 1). Male apodeme slightly sclerotized and thin, without ventral lobe ( Fig. 3AView Figure 3).

Male genitalia. Gonarcus thick with wide and elongate lateral plates ( Fig. 3CView Figure 3); entoprocessus elongate, with evenly tapering tips ( Fig. 3BView Figure 3); gonocornus lacking. Arcessus very long, narrow, straight, with downward curved apical point ( Fig. 3BView Figure 3). Gonosaccus basally with gonosetae ( Fig. 3AView Figure 3). Gonapsis elongate, extending from base of gonosaccus, slightly upturned, terminating internally in a smoothly rounded apex ( Fig. 3EView Figure 3), with sclerotized microteeth on dorsal side ( Fig. 3DView Figure 3); membranous sac between apices of gonapsis and sternite 9 with a field of well-developed gonocristae ( Fig. 3AView Figure 3).

Female. Similar to holotype. Female genitalia. Female subgenitalia as wide as long, with rounded apex and narrow medial notch ( Fig. 3GView Figure 3); spermatheca well sclerotized, with vela broad basally and strongly arched apically; spermathecal duct slightly sinuous before entering oviduct; ventral impression conspicuous ( Fig. 3FView Figure 3).

Variation.

Lateral stripes of pronotum are variable, for instance whether they are continuous or interrupted ( Fig. 2A, BView Figure 2), thickened or narrow ( Fig. 2C, DView Figure 2), pale or dark red ( Fig. 2E, FView Figure 2); also, dorsolateral marks of the abdomen are generally orange, but may be reddish brown.

Etymology.

This species is named after the Tacaná Volcano, located in the state of Chiapas, Mexico, where the specimens were collected.

Ecology.

This species is presently known from cloud forest (1,430-1,705 m a.s.l.) and mixed oak-cloud forest (2,060-2,430 m a.s.l), and with similar collecting techniques and collecting effort, it was not found at lower (661-1,393 m a.s.l.) or higher (2,884-3,246 m a.s.l) elevation collecting sites. Specimens were found on Alinus  sp., Quercus  sp., and Saurauia  sp., and were collected from February through May, August through December 2018, and January 2019.
