Callibaetis stictogaster Navás 1915 revalidated species
( Figs. 17 View FIGURE 17 A–18E)
Callibaetis stictogaster Navás 1915b: 121 ; Gillies 1990: 28. (previously syn. with C. jocosus View in CoL by Gillies 1990)
Known stages. I ♀♂.
Diagnosis. Male imago: 1) costal margin of forewing with pigmentation extending beyond R1 and less intense after R2 ( Fig. 17 View FIGURE 17 D); 2) marginal intercalary veins paired ( Fig. 17 View FIGURE 17 D); 3) hind wing with pointed costal process; 4) marginal intercalary veins present on hind wing.
Female imago: 1) forewing completely brown ( Figs. 17 View FIGURE 17 F, 18C, 18D); 2) marginal intercalary veins paired ( Figs. 17 View FIGURE 17 F, 18C, 18D); 3) hind wing with brown marks ( Fig. 18 View FIGURE 18 E); 4) hind wing with pointed costal process ( Fig. 18 View FIGURE 18 E); 5) marginal intercalary veins on hind wing present ( Fig. 18 View FIGURE 18 E); 6) abdominal terga and sterna covered with brown spots ( Figs. 17 View FIGURE 17 B and 18A); 7) abdominal terga with longitudinal mark medially, near anterior margin; 8) anterior margin of terga II–IX with one pale triangle, inside of it with spots ( Fig. 18 View FIGURE 18 A); 8) abdominal sterna with pigmented medioanterior and medioposterior sigilla ( Fig. 18 View FIGURE 18 B); 9) abdominal sterna with two large brown marks on anterior margin, one medially and other anterolaterally ( Fig. 18 View FIGURE 18 B).
Redescription. Female imago: Head. Yellowish with red “M” mark ( Fig. 18 View FIGURE 18 A). Thorax. Anteronotal protuberance rounded. Metascutellar protuberance pointed. Wings. Forewing completely brown, with hyaline cross veins ( Figs. 18 View FIGURE 18 C and 18D); stigmatic area with 12 cross veins touching Sc vein; marginal intercalaries paired; length of each intercalary vein 0.9 × distance between adjacent longitudinal veins; length of forewing about 2.8× width. Hind wing ( Fig. 18 View FIGURE 18 E) with some brown marks; with two intercalary marginal veins; costal process pointed. Abdomen. Terga ( Fig. 18 View FIGURE 18 A) with longitudinal mark medially, near anterior margin, and small light brown spots; anterior margins of terga II-IX each with one white triangular mark, inside with spots. Sterna ( Fig. 18 View FIGURE 18 B) covered with reddish spots; with one longitudinal line medially; two large brown marks medially and anterolaterally, medial mark formed by spots. Caudal filaments light brown, segments brown at base and apex.
Comments. The female imago of C. stictogaster revalidated species can be distinguished from C. (C.) jocosus , C. (C.) zonalis , C. (C.) willineri , C. (C.) guttatus and C. (A.) dominguezi , as well other species of the genus, by the following characteristics: forewing completely brown ( Figs. 17 View FIGURE 17 F, 18C, 18D); marginal intercalary veins on hind wing present ( Fig. 18 View FIGURE 18 E); abdominal terga and sterna covered with brown spots ( Figs. 17 View FIGURE 17 B and 18A); anterior margin of terga II–IX with one white triangular mark, inside of it with brown spots ( Fig. 18 View FIGURE 18 A); and abdominal sterna with two large brown marks on anterior margin, one medially and other anterolaterally ( Fig. 18 View FIGURE 18 B).
Based on the re-evaluation of the morphological evidence, we propose the revalidation of Callibaetis stictogaster revalidated species and designate the female imago housed in MZLP as lectotype ( Figs. 17 View FIGURE 17 A and 17B), the male imago housed in MZLP as paralectotype ( Figs. 17 View FIGURE 17 C and 17D) and the female imago housed in MZB as paralectotype ( Figs. 17 View FIGURE 17 E and 17F).
Females collected from Brazil possess egg–nymph development inside their abdomens, indicating a possible ovoviviparous mode of reproduction.
