Etymology. This species is named mauffrayi after our good friend and colleague William Mauffray, collection manager of the Odonata collection at FSCA, who has always come to our aid in our work on neotropical Odonata .

Description. Holotype dimensions: Hw 16.1; abdomen 27.5; total length 29.5. Head of male holotype with labium ivory, remainder of head including epicranium dull orange brown becoming olive green on postocular regions ( Fig. 1 c), paler on rear of head, dark brown along postfrontal suture, and spot posterior to postfrontal suture.

Prothorax dull olive brown, paler along pleural areas, hind lobe of prothorax evenly rounded; pterothorax entirely olive blue with diffuse orange brown thoracic stripes along medial portion of mesepisternum and mesopleural suture, remainder of thorax paler laterally. Costal side of Fw pt rhomboid, subequal to basal side, its posterior margin slightly convex. CuA ending five cells distal to vein descending from subnodus (just beyond level of 3rd Px). Wings hyaline, Px Fw 10; Hw 9 (8 right); RP 2 originating at Px 5 in Fw, at Px 4 in Hw; pterostigma 0.4 mm long. Legs ivory with wash of brown at distal margin of femora, spines black.

On abdomen, S1 with brown spot dorsally, pale olive brown laterally and dorso-distally; S2 pale orange dorsally with wash of brown at subapical eighth of segment, sides becoming pale olive green; S3–7 dark brown dorsally, pale orange laterally; S3–5 with brown apical ring; S8–10 dark like S3–7 but with brown extending laterally; S8 with dorsal dark spot on basal 0.70, basal portion and sides dull blue with wash of brown laterally; S9 pale blue; S10 like S9 but with irregular basal half ring of brown. Genital ligula in ectal view ( Fig. 13 b, paratype) with sides parallel, distal margin shallowly concave and armed latero-dorsally with row of fleshy papillae; in lateral view ( Fig. 13 a, paratype) with distal portion of segment roughly semicircular and ending ventro-apically in a short, conical sclerotized tubercle followed by a lateral posteriorly directed chitinized flap-like process which tip ends in a spine, inner fold present but small. Cercus longer than wide, posterior half angled ventrally ( Fig. 20 e) and with a short ventro-basal prominence medially ( Fig. 22 c); paraproct slender, acuminate, in lateral view, its tip slightly surpassing tip of cercus ( Fig. 21 e).

Female allotype with head entirely dark olive blue becoming paler along genae and postocular region; anteclypeus dark brown. Thorax as in male but dark olive blue; hind lobe of pronotum ( Fig. 5 e) evenly rounded. Wing venation as in male but CuA ending five cells beyond vein descending from subnodus (at level of 4th Px) in Fw, at four cells beyond vein descending from subnodus (at level of 3rd Px) in Fw. Wings hyaline, Px Fw 11 (both wings); Px Hw 9 (left)/ 10 (right); RP 2 originating at Px 5 in Fw, at Px 4 in Hw; pterostigma 0.5 mm long. Abdomen as in male but shorter, more robust, and S8–10 dark brown above and blue laterally; ovipositor surpassing tip of cerci for a distance subequal to length of cerci ( Fig. 19 d). Dimensions: Hw 18.8; abdomen 31.0; total length 37.0.

Variation in paratypes. The male from Tambopata is similar to the holotype but the dorsum of prothorax and the mid-dorsal and humeral stripes are dark and contrasting to remainder of thorax, the dark abdominal markings are more defined than in the holotype, and all of S8–10 is pale blue; two males from Cucharas differ by having all of the head, thorax, and S1–2, and all of S3 except apical tenth orange, remainder of abdomen dark brown except for hint of pale annuli. The female paratype from Pakitza is similar to the allotype but the blue coloration is paler; female from Tambopata is a juvenile with head and thorax orange with similar head markings as for holotype and with faint hint of blue between mid-dorsal and humeral orange of thorax, abdomen dorsally dark brown on S2–6 with apical tenth extending laterally to form incomplete apical ring, S8 with basal half dark, S9 with divided dorsal spot at basal 0.50, remainder of abdomen orange becoming paler laterally.

Dimensions. Males (n = 10, including holotype): Hw 16.1–19.9 (17.1); abdomen 26.0–30.7 (28.7); total length 32.0–36.7 (34.1). Females (n = 10): Hw 17.2–19.7 (18.3); abdomen 26.0–31.0 (28.2); total length 32.0–37.0 (34.0).

Diagnosis. Leptobasis mauffrayi is one of three allopatric species of the Leptobasis vacillans group which also includes L. raineyi ; all share a similar pronotal, thoracic, and caudal appendage morphology. Examination of the genital ligula is necessary to confirm identification. The genital ligula of males of L. mauffrayi has a short ventro-apical, conical sclerotized tubercle ( Figs. 13 a, c) that is lacking in L. raineyi ( Fig. 15 a) and L. vacillans ( Fig. 16 a). In the field adults can usually be identified by overall abdominal color pattern, which is largely blue in L. mauffrayi and L. raineyi , and with some orange or red in L. vacillans . However, we have seen pale female L. vacillans ( Panama) which are ochraceous and similar to L. mauffrayi . Leptobasis mauffrayi replaces L. vacillans in Peru but further collecting may show both species to occur sympatrically.
