Lestes apollinaris Navas  (Figs. 1,4,5,8,11,14,16)

MALE: Dark colors black with red reflections anteriorly grading to greenish reflections posteriorly. The pale color is pale blue dorsally, grading to yellow-cream

HEAD: Rear of head dark, pale color restricted to portion of head close to articulation with thorax; labium white; vertex, frons, and postclypeus dark; anteclypeus and labrum blue.

PROTHORAX: fore lobe brown, lateral margins bluish; middle lobe with medial pale stripe which is narrowed anteriorly and is flanked by dark bands continuing the dark dorsal stripe of mesepistemum, laterally blue; proepimeron and proepistemum dark dorsally, obscure brown ventrally, continuing dark stripes of mesepimeron; hind lobe low laterally, produced centrally into rounded, recumbent lobe which has a central rounded emargination ( Fig. 11View Figs).

PTEROTHORAX ( Fig. 1View Figs): Mesepistemum dark, tapered antehumeral pale stripe occupying 40% of segment width anteriorly and 25% posteriorly, sharply narrowed in apical 4/5; dark stripe on mesepimeron well defined and occupying central 3/5 of sclerite, anterior end ventrally excavated and bordered there by diffuse brown, this stripe continuing to prothorax. Remainder of sides of thorax pale, grading from pale blue dorsally to creamy yellow ventrally; poststernum pale, with a pair of elongate, oval lateral dark spots in anterior half The thorax viewed ventrally is pale with two staggered rows of rounded dark spots: two on the metepimeron (anterior and posterior, immediately below the lateral carina) and one, more elongate, on the poststernum.

LEGS: Coxae and trochanters pale, femora and tibiae pale with vivid dark longitudinal external stripes, tarsi and claws dark.

WINGS: Venation black, pterostigma dark red, quadrate, width about 1/3 the length. 14-15 postnodal crossveins in fore wing, 12- 13 in hind wing.

ABDOMEN: Segment 1 pale, dorsally dark in anterior half, this color extended rearward on lateral margins to produce a pattern of paired “horns”, enclosing blue posterior dorsal color, lateral margins of segment brown, the dark color extended dorsally on apical margin to form rounded “L” marks; 2 dark dorsally, broadly pale blue ventrally; dorsal thin pale line on anterior 3/4; 3 to 8 dark dorsally, greenish reflections grading to red posteriorly; pale blue apical rings on 3 to 7, dorsally interrupted, and diminishing in size posteriorly; pale laterally, narrowed in posterior 1/5 (segment 3) to 1/3 (8); 9 and 10 dark with pale lateral margins; 9 heavily pruinose.

APPENDAGES ( Figs 4, 5, 8View Figs): Cerci dark, elongate, parallel sided, bent apically with prominent dorsal carina; medial margin with an acute tooth in basal third, the margin beyond this tooth nearly straight and very lightly denticulate. Paraprocts brown, a third of the length of the cerci, with rounded, blunt apices, medially deflected apically, the ends enclosing a small but well defined rounded medial sinus.

FEMALE: Dark colors more reddish than male, with the pale colors yellow in various shades but not bluish. The color pattern similar to that of male, differing mainly in the postclypeus, which has pale lateral spots. The ovipositor extends to about the middle of the 10th segment.

The species is closest to tenuatus  , rather than henshawi  as Navas stated. However, there are similarities among the three species, which are compared in the following table (the female of henshawi  was not available for comparison).
