Body ( Figs 98 ─105) not strongly depressed dorsoventrally. Head (Figs 99, 102) narrower than pronotum. Crown slightly produced, surface slightly concave and with transverse striae; transition to frons distinct, thick and transversely striated. Ocelli large, each equidistant from eye and median line of crown and slightly nearer anterior margin of crown. Clypeus with epistomal suture obscure. Antennal ledge, in lateral view, carinate and oblique. Pronotum (Fig.30) declivous and transversally striated. Scutellum (Figs 6, 78) inflated as round tubercle. Forewing (Fig. 7) with R1 present and three closed anteapical cells; without extra crossveins; appendix well developed. Fore leg with femora with AD, AM and PD rows reduced and poorly defined, with exception of apical setae AD1, AM1 and PD1, respectively; AV and PV rows formed by few and sparse setae, AV row restricted to proximal half and PD row restricted to distal half of femur; IC row formed by slightly arched comb of fine setae, beginning at distal half of femur and extending out to AM1; tibiae without intercalary row. Hindleg with femoral setal formula 2:2:1; tibiae with row anterodorsal (AD) without intercalary microsetae between macrosetae; first tarsomere as long as two more distal tarsomeres combined; one row of short setae on plantar surface. Male sternite VIII (Figs 8, 68) wider than long; posterior margin with rounded lateral corners and slight to more pronounced median concavity. Pygofer (Figs 9, 21) slightly longer than basal height; apical margin with many microsetae, macrosetae dispersed on posterodorsal quadrant; apical margin with many microsetae. Valve (Fig.69) fused to base of pygofer. Subgenital plate (Figs 34, 70) about three times longer than maximum width; produced posteriorly as far as pygofer apex; outer margin slightly convex; without conspicuous setae, only few microsetae along outer margin. Connective (Figs 23, 47) Y-shaped; stem broadened apically. Style elongate and narrow; in dorsal view (Figs 71, 93), with well-developed outer rounded lobe next to connective apex; region posterior to outer lobe, in lateral view, as long as or longer than anterior portion, mostly straight with apex narrowed and turned upwards, apical ventral margin serrate (Fig. 36) or not (Fig. 48). Aedeagus (Figs 14, 50) with shaft elongate; apical portion expanded with one or more pairs of acute processes; preatrium not developed; dorsal apodemes well developed and divergent in posterior view, without processes. Coloration. Head and thorax ( Figs 98 ─105) yellow with light- and dark-brown maculae. Crown ( Figs 76 , 90) with median black longitudinal stripe. Frons (Figs 17, 77) with black bands over muscle impressions. Clypeus with median spot (may be composed of small dots) and paired lateral small spots over epistomal suture, black. Lora light yellow with black spots near clypeus margin. Genae black on superior portion. Pronotum ( Figs 16 , 64 ) with irregular black spots laterally near anterior margin, commonly with larger C- or L-shaped black maculae just behind eyes; punctures brown. Scutum may have irregular median light- or dark-brown maculae; anterior margin with paired large lateral subtriangular black or dark-brown maculae. Scutoscutelar suture dark-brown. Scutellum with brown apex. Forewing strongly marked by dark-brown mottling (Figs 7, 19); subhyaline areas mostly along costal margin, bases and apices of anteapical and discal cells, bases of apical cells, along apical portion of claval commissure, and mid-portion of appendix. Legs yellow with black spots. Distribution. Brazil , Ecuador [new record], French Guiana , Panama , and Peru [new record]. Regalana species occur in very different forest types in Central and South America ( Fig. 1 ), such as the Cerrado savannah in Central Brazil and lowland and montane Amazonian/Andean rainforests, ranging in altitude from 0 to 2,000 m a.s.l.
