Ecliptoides julietae sp. nov.

( Figs. 1A, 1B )

Holotype: male. Size 5.6 mm. Deposited at MNKM.

Diagnosis: Males of E. julietae sp. nov. differ from other species by the blackish pronotum and sterna; the females from other Bolivian species by its entirely black humeri; and from E. hovorei of French Guiana by the elytral pubescence (fine and sparse in E. julietae sp. nov., dense and silky in E. hovorei ); from E. azadi by the colour of the scutellum (black in the French Guiana species, orange in the Bolivian); and from E. hovorei by the colour of metafemoral peduncle (apex black in the French Guiana species, entirely yellow in the Bolivian one).

General colour: chestnut and orange to yellow. Head, prothorax, scutellum, meso- and metasternum blackish. Antenna: scape, pedicel, antennomeres III and IV, apical 3/4 of V and 2/3 of VI dark chestnut, apical half VII-X brown, XI brown. Elytra, including basal fifth and humeri, opaque orange; sides broadly dark brown from basal fifth to apex; extreme apex dark brown. Abdomen translucent orange-yellow, visible tergites opaque brown. Legs, including coxae, yellow, except: dorsad and apex of mesofemoral club, all of metafemoral club and tarsi chestnut; meso- and metatibia, except extreme base almost black. Apex of wings dusky.

Structure: Head. Inferior lobes very large (1.6 x 1.4 units) and convex, together slightly wider than pronotum; underside almost entirely carinate with large regularly spaced punctures. Antenna long, passing tip of elytra at middle of antennomere X, and reaching middle of urosternite III; antennomere III slightly shorter than V.

Thorax. Prothorax 1/4 longer than wide, front and hind borders subequal, sides subparallel, not constricted. Pronotum convex, slightly depressed at centre of basal half and narrowly to hind angles, this flattened area bounded laterally by two inconspicuous calli; apical half hirsute; disc with scabrous, subcontiguous punctures, sides mostly smooth with sparse punctures, almost entirely occupied by harp-shaped patch of dense, sericeous pubescence. Elytra not strongly dehiscent, sides subparallel for apical half, gradually narrowed to apex; apex oblique, protracted laterally into blunt tooth, reaching apex of urosternite II; more or less punctured throughout, denser at sides; hirsute for basal half, from base to apex with sparse, short, fine pubescence.

Abdomen. Narrow, fusiform; widest at apex of urosternite II; length of I-III subequal; V trapezoidal; shallow, V-shaped depression from apex to base; apical border straight. Apex of protibia slightly thickened laterally.

Female sexually dimorphic: General colour: semitranslucent orange and black or dusky. Head, scutellum, and entire underside orange-yellow; pronotum orange-yellow with moderately narrow, unshapely candelabrum; elytra orange yellow, sides and apex broadly blackish. Antenna black basally, becoming increasingly browner to apex; antennomeres without pale annuli. Dorsad of pro- and mesofemoral claves dusky.

Structure: inferior lobe 1.7 x 1.2 units, interocular space (0.9 units) with 2-4 rows of dense punctures; antenna just reach apex of elytra, and apex of urosternite II. Elytral dehiscence stronger, apices of elytra transversely truncate and unarmed. Mentum with three carinas, submentum and gula smooth with large, sparse punctures. Mesosternal process straight. Abdomen as male but more robust, and urosternite V regularly convex.

Variation: Apices of elytra of some males less oblique, and reaching basal 1/4 of urosternite III. Elytra of some females more strongly dehiscent and antennae somewhat thickened from antennomere III to apex. In both sexes some reduction in size and shape of pronotal candelabrum, and extent of dusky pigmentation at sides of elytra.

Measurements (mm) 21♂ / 16♀: total length 4.7-6.1/5.5-6.6; length of pronotum 0.9-1.2/1.1-1.3; width of pronotum 0.7-0.8/0.8-1.0; length of elytra 2.3-2.7/2.6-3.0; humeral width 0.9-1.0/1.0-1.2.
