Saica meridionalis Fracker & Bruner 1924

Saica meridionalis Fracker & Bruner, 1924 (Figs 3E, F; 6J; 8) Saica meridionalis Fracker & Bruner, 1924: 164 [descript.]. — Maldonado Capriles 1990: 479 [cat.]. — Gil-Santana & Marques 2005: 405 [cit.]. — Castro-Huertas & Melo 2023: 6 [phylogenetic analyses]. MATERIAL EXAMINED. — Holotype. Brazil • ♀; Amazonas: Manaos; 15.XI.1919; Flores; USNM 51735 (high-resolution image). OTHER MATERIAL EXAMINED. — Colombia • 1 ♀; Santander: La Belleza; Ver. Los Naranjos; 21.III.1997; H. Marin; UNAB. Guyane • 1 ♀; CSG Kourou; 16.X.2007; coll. JMB • 1♀; Delanglade: La Victoire; 5.VI.1997; B. Hermier; coll. JMB • 1♀; Mt des singes; 26.VIII.1996; Vesco J.P. réc.; coll. JMB. DIAGNOSIS. — Forewing with three closed cells, posterior margin of abdominal tergite 7 in females with a pair of caudolateral spiniform protruding processes (Fig. 3E), apex of the gonoplac rounded (Fig. 6J). DISTRIBUTION. — Brazil (Amazonas) (Maldonado Capriles 1990). First records for Colombia and French Guiana (Fig. 8). REDESCRIPTION Female Macropterous. Measurements in Table 2. Coloration (Fig. 3 E-F). Head: Reddish to brownish. Scapus dark brown with reddish on basal and apical regions. All labial segments reddish. Thorax: Reddish, apex of the spines slightly dark red to yellowish. Procoxal cavity red, procoxa and protrochanter reddish, profemur dark brown with basal and apical regions reddish, protibia dark brown with basal portion reddish and apical portion pale brown, protarsus yellowish; meso- and metalegs similar to proleg except by the meso- and metatibiae dark brown with the base reddish. Forewing yellowish with veins and pterostigma reddish to yellowish apically. Abdomen: Entirely reddish. Structure. Thorax (Fig. 3F): Humeral angle spines nearly two or three times longer than their base. Mesonotal spine straight, three times longer than its base. Protuberance of scutellum with its apex slightly concave, conspicuously concave posteriorly, lateral margins slightly expanded in caudal view. Metanotal spine straight, nearly 0.5 times the length of mesonotal spine. Forewing with three closed cells, apex of outer discal cell extending as far as apex of pterostigma. Abdomen: Abdominal tergite 2 not conspicuously narrower than the other abdominal tergites. Posterolateral angles of tergite 7 with a pair of spines. Genitalia: Tergite 9 nearly oval. Apex of gonoplac entire, with external margins rounded (Fig. 6J). Male Macropterous. Male specimens were not examined here; but the original description referred to a male paratype as very similar to the female holotype [male genitalia not described or illustrated]. Forewing with three closed discal cells, membrane just reaching apex of abdomen in both sexes. REMARKS Saica meridionalis is similar to S. apicalis, as both species have three closed cells on the forewing; nevertheless, S. meridionalis shows longer humeral angle spines, the females have the protruding processes on the posterolateral angles of the abdominal segment 7, and the apex of the gonoplac is rounded. Unfortunately, the posteromedial process of the pygophore was not described in the original description, and the male paratype was not found for this study.
