( Figs 4 E-F; 5H; 8)

Saica subinermis Hussey, 1953: 64 . — Maldonado Capriles 1990: 479 [cat.]. — Swanson 2020: 978 [cit.].

MATERIAL EXAMINED. — Holotype. Mexico • ♂; Michoacán: 12 ml.s Tzitzio on Huetamo rd.; 19°20’N, 100°50’W; 1050 m; 10.VII.1947; T. H. Hubbell / Holotype, Saica subinermis 1952, Hsy, Det. R. S. Hussey; UMMZ (high-resolution images, Fig. 4E, F ) .

DIAGNOSIS. — Body coloration reddish with basal half of femora and tibiae entirely orange ( Fig. 4E, F ); spines of humeral angles short ( Fig. 4E ); posteromedial process of pygophore medially concave with ramus laterally projected ( Fig. 5H ).

DISTRIBUTION. — Mexico ( Hussey 1953) ( Fig. 8 ).

REDESCRIPTION

Male

Macropterous. Measurements in Table 2 .

Coloration ( Fig. 4 E-F). Head: Reddish. Antenna orange. Labium reddish. Thorax: Reddish, apex of meso- and metanotal spines yellowish. Procoxal cavity, procoxa and protrochanter orange; profemur basally orange, apically reddish; proti - bia orange, basally reddish, protarsus orange; meso- and metalegs similar to proleg. Forewing yellowish with veins orange, pterostigma reddish. Abdomen: Orange, pygophore slightly darker.

Structure. Thorax ( Fig. 4F ): Humeral angle spines short, as long as their base. Mesonotal spine sinuous, near twice as long as its base. Protuberance of scutellum with apex slightly concave posteriorly, lateral margins not expanded in caudal view. Metanotal spine sinuous, nearly 0.5 times the length of mesonotal spine. Forewing with two closed cells, apex of outer discal cell extending as far as apex of pterostigma. Abdomen: Abdominal tergite 2 not conspicuously narrower than rest of abdomen. Genitalia: Posterior margin of ramus flat; posteromedial process of pygophore (mpp) deeply concaved medially ( Fig. 5H ); ramus angulated and projecting laterally, nearly twice as long as its base, apical region narrowed.

REMARKS

Saica subinermis is similar to S. apicalis , considering the short length of the thoracic spines of both species; but S. subinermis can be distinguished by the two closed cells on the forewing, the reddish pattern of the femora basally, the entirely orange tibiae, and laterally projected rami of pygophore. Species only known from the male holotype.
