Callibaetis jaffueli Navás 1918 revalidated species

( Figs. 6 View FIGURE 6 A–6E)

Callibaetis jaffueli Navás 1918: 214 ; Gillies 1990: 25; Domínguez et al. 2006: 115 (previously syn. with C. jocosus View in CoL by Gillies 1990)

Known stages. I ♂.

Diagnosis. Male imago: 1) forewing with pigmentation overlapping R 1 in five regions, overlapping radial sector medially, without forming complete bands ( Fig. 6 View FIGURE 6 B); 2) marginal intercalary veins paired ( Fig. 6 View FIGURE 6 B); 3) hind wing with small brown mark at middle ( Fig. 6 View FIGURE 6 C); 4) hind wing with pointed costal process ( Fig. 6 View FIGURE 6 C); 5) marginal intercalary veins on hind wing present ( Fig. 6 View FIGURE 6 C); 6) abdominal terga brown, with few spots and dark longitudinal mark at middle ( Fig. 6 View FIGURE 6 E); 7) abdominal terga III, V and VI without lateral inverted V mark; 8) abdominal sterna covered with spots ( Fig. 6 View FIGURE 6 D); 9) abdominal sterna with strong pigmented medioanterior and medioposterior sigilla ( Fig. 6 View FIGURE 6 D).

Redescription. Male imago. Length: body, 6.5 mm; forewing, 7 mm; cerci 8.6 mm. Head. Compound eyes with brown turbinate portion. Antenna with brown scape, pedicel and flagellum. Thorax. Anteronotal protuberance brown medially; posterior scutal protuberance and scutellum brown. Anteronotal and metascutellar protuberance rounded. Legs: Tibia I with brown marks apically. Wings. Forewing with pigmented C and Sc areas, overlapping R 1 in five regions, third region overlapping Radial sector ( Fig. 6 View FIGURE 6 B); veins light brown; marginal intercalary veins paired; length of each intercalary vein 0.7 × distance between adjacent longitudinal veins; length of forewing about 2.6 × width. Hind wing with small brown mark at middle ( Fig. 6 View FIGURE 6 C); costal process pointed; three marginal intercalary veins. Abdomen. Terga. Brown, with some spots and dark longitudinal mark in middle ( Fig. 6 View FIGURE 6 E); terga III, V and VI without lateral inverted V mark. Sterna. Light brown, covered with spots and with well pigmented medioanterior and medioposterior sigilla ( Fig. 6 View FIGURE 6 D). Genitalia. Forceps light brown and badly damaged.

Comments. Callibaetis jaffueli revalidated species can be differentiated from C. (C.) jocosus , C. (C.) zonalis , C. (C.) willineri and C. (C.) guttatus by the abdominal sterna medially, on anterior margin, without one large spot (in contrast to C. (C.) willineri ); marginal intercalary veins on hind wing present (in contrast to C. (C.) zonalis ); terga III, V and VI without lateral inverted V mark ( Fig. 6 View FIGURE 6 E) (in contrast to C. (C.) guttatus and C. (C.) jocosus ); and the forewing with pigmentation overlapping R 1 in five regions, overlapping radial sector medially, without forming complete bands ( Fig. 6 View FIGURE 6 B) (in contrast to C. (C.) jocosus ).

Based on the re-evaluation of the morphological evidence, we propose the revalidation of Callibaetis jaffueli revalidated species Navás and designate the unique known specimen as lectotype.

Material examined. Callibaetis jaffueli , male imago (lectotype by present designation, dry), CHILE, Los Perales, Marga-Marga, i.1918, P. Jaffuel coll., MZB.
