Diagnosis
Cyrea mcclarini sp. nov. has a distinctive dorsal elytral pattern rarely found in ladybird beetles, with a turquoise colored maculae in living specimens (Fig. 1D–E) by which it may be easily recognized. In dried specimens the turquoise color disappears and the maculae become yellow (Fig. 1A–C). However, the unique double C pattern on each elytron (Fig. 1B, D) distinguish this species from all other known species. Males have parameres unmodified, which places this species in the tredecimguttata group as defined by Canepari et al. (2016). Males can be separated by the following characters: presence of distinct, small, subtriangular projections on the posterior margin of ventrite 6 (Fig. 2B), large angulate projections on the posterior margin of tergite X (Fig. 2G), penis guide with truncate apex (Fig. 2L), tip of penis with spine like projections on both sides (Fig. 2J), and peculiar shape of inner sclerites in the apical part of penis (Fig. 2I–J). Females can be distinguished by distinctly shaped additional sclerites in the bursa copulatrix and a large rounded projection on the ventral surface of bursa (Fig. 2D–E).
Etymology
This species is dedicated to Jim McClarin from Consanga, Napo, Ecuador, who kindly provided images of living specimens.

Body oval (Fig. 1A, D), convex (Fig. 1B), winged; head black with turquoise frons and vertex in male and frons in female (Fig. 1E), pronotum black with three turquoise spots: one longitudinally elongate placed medially and two rounded on pronotal anterior corners, in males all spots fused with yellow anterior pronotal margin, in females separate (Fig. 1E); elytra black with five maculae on each elytron (2+2+1): humeral, anteromedian and discal spots oval, lateral and posterior spots C-shaped (Fig. 1B, D); ventrally (Fig. 1F) anterior part of hypomera turquoise; antennae, legs except coxae and abdomen reddish-brown; hypomera except anterior part, prosternum, meso- and metaventrite, coxae and epipleura black; mouthparts infuscate; mesepimeron in male turquoise. In death, turquoise color disappears and turns yellow. Dorsum glabrous, with single size punctures. Punctures on elytra less coarse than on head and pronotum. Head with microreticulation between punctures.
HEAD. Head partially covered by pronotum dorsally (Fig. 1E); ventral antennal grooves distinct, straight along eye margin. Eyes prominent, finely facetted, dorsally with inner orbits arcuate; ocular canthus present, as long as 4–5 ommatidium diameters; interocular distance about 0.50 × as wide as head across eyes; interfacetal setae absent. Antenna short, 0.35 × as long as head capsule width, composed of 11 antennomeres; scape simple, without projections; pedicel narrower than scape, barrel-shaped, about 1.20 × as long as wide; antennomere 3 about 1.20 × as long as pedicel. Antennal club consisting of three antennomeres, elongate, slender; antennomere 9 and 10, subequal in length; antennomere 11 elongate, obliquely truncate apically. Anterior clypeal margin straight. Labrum truncate at apex. Mandible bidentate at apex. Maxillary cardo transverse with outer angle reaching slightly outside of mouth cavity; terminal palpomere securiform, truncate obliquely. Submentum transverse; mentum sub-trapezoidal with anterolateral lobes projecting forwards, anterior edge strongly emarginate, ventral surface with lateral grooves along edges; prementum transverse; labial palps separated by distance about equal to width of palpomere; apical palpomere as long as penultimate one. Gula with distinct pore.
PROTHORAX. Pronotum with anterior corners rounded, obtuse (Fig. 1C); anterior, lateral and hind margins without bordering line. Prothoracic hypomeron smooth; notosternal suture distinct; prosternal process slightly widened apically, apex truncate; without carinae.
