039D87F1FFA1187BFF79F885116FFC12.taxon	diagnosis	Diagnosis. Medium to small size (i. e. about 8 to 10 mm), elongated body, usually dark coloration, a broad antennal segment I, antenniferous tubercule with a little tooth (nearly vestigial in some species), bucculae elongated and evanescent in the posterior end, rostral segment I surpassing the bucculae, pronotum subtriangular with two rounded convex processes oriented posteriorly near humeral angles, anterolateral angles with two spine-like processes projected anteriorly, scutellum equilaterally triangulate, ostiolar peritreme short (reaching 1 / 3 of metapleuron), tibiae sulcate, and base of abdomen with a median truncate process. Bionomics. The biology of the species of Eldarca is nearly unknown, only E. nigroscutellata sp. nov. is known to be associated with dunes, lower vegetation and alkaline environments; however I have observed different photos of E. haematomera and E. rufa, collected in dunes and / or lakes shores. Therefore I believe that this behavior and niche is shared by all the species on this genus. Additionally I believe possible the presence of several more undescribed species, but more collecting efforts are needed to get more specimens available to study.	en	Faúndez, Eduardo I.

039D87F1FFA1187BFF79F885116FFC12.taxon	distribution	Distribution. The genus Eldarca is currently represented by 4 species distributed from Central Chile, to Southern Patagonia in Chile and Argentina (Fig. 12), showing a classical Andean distribution. Eldarca haematomera is distributed in the Central Zone and surrounding area of Chile (mainly in highlands of Mediterranean zone) from Coquimbo to Maule Regions. This species was cited from Argentina by Pennington (1920, 1922) and Breddin (1897), but those records belong mainly to E. nigroscutellata; and the presence of the species in the middle of the country needs verification. Eldarca nigra was described just from “ Chili ” and the only exact known location is in the Araucanía Region, south of Chile. Eldarca rufa is distributed from Maule to Araucanía Regions in the south of Chile. Eldarca nigroscutellata is restricted to Magallanes Region in Chile and Santa Cruz province in Argentina, both in Southern Patagonia, which makes this species the southernmost distributed Coreid in South America.	en	Faúndez, Eduardo I.

039D87F1FFA5187EFF79FF691644FD8D.taxon	discussion	Comment. This taxon was erected by Reed (1899) as a variety of E. haematomera; actually according the ICZN (1999) it has subspecific rank. The Reed syntypes are two females in poor condition; these types match with a small series of female specimens examined from O’Higgins region in Chile. There is one male from Coquimbo region which has a similar pattern and a very different pygophore, it could belong to this species or to an undescribed one. To clarify the situation of this taxon the examination of more material is needed, especially males associated with females. For this reason we currently consider it a valid subspecies of E. haematomera.	en	Faúndez, Eduardo I. (2015): Synopsis of the genus Eldarca Signoret, 1864 (Hemiptera: Heteroptera: Coreidae).

039D87F1FFA5187EFF79FD3A1067FAC2.taxon	discussion	Comment. This species is so far known only from the type specimen and its type locality “ Chile ”. Porter (1917) gave some records in the Araucanía Region and the far north; however the locality in the north is doubtful and very improbable. Additionally the specimens are not available for study. Thus we currently consider this species restricted to the Araucanía Region in Chile (Fig. 12).	en	Faúndez, Eduardo I.

039D87F1FFA5187FFF79FA861159FE05.taxon	discussion	Comments. This taxon was erected by Reed (1899) as a variety of E. haematomera from Cauquenes, Maule, Chile. The discovery of the Reed’s type material and newly collected specimens helped to define its taxonomic situation. The general coloration as well as male and female genitalia differs significantly from E. haematomera (see Figs. 4, 8, 11 and 2, 6, 10). In addition, both species differ in distribution (Fig. 12). Thus we believe this taxon deserve full specific rank. The lectotype of this species according to Reed (1899) was collected on Maule Region which is the northern distribution limit of this species.	en	Faúndez, Eduardo I.

Eldarca nigroscutellata sp. nov. can be differentiated from E. nigra by having ivory borders of pronotum and connexiva; whereas E. nigra is completely black; also in the female genitalia, the first gonocoxae are more truncated in E. nigroscutellata, whereas it is more rounded in E. nigra; the paratergite VIII is subrectangular in E. nigroscutellata; and rhomboid in E. nigra. From E. haematomera it can by differentiated by the male pygophore which is pentagonal in E. nigroscutellata and square shaped in E. haematomera n the female genitalia the first gonocoxae are slightly pointed apically in E. nigroscutellata and very acute apically in E. haematomera; the scutellum is unicolor in E. nigroscutellata, whereas it has ivory bands on the sides in E. haematomera. From E. rufa it can be differentiated by the dorsal coloration which is blackish blue in E. nigroscutellata and reddish in E. rufa; the scutellum is unicolor in E. nigroscutellata, whereas it has ivory bands on the sides in E. rufa; the legs are bicolor in E. nigroscutellata, whereas legs are unicolor in E. rufa; the male pygophore has nearly straight lateral margins in E. nigroscutellata; the lateral margins in E. rufa are strongly inclinated and convex; in the female genitalia the first valvifer is more pointed in E. rufa than in E. nigroscutellata, and the first paratergites are subrectangular in E. nigroscutellata; and rhomboid in E. rufa.	en	Faúndez, Eduardo I.
