Coenypha fasciata Mello-Leit „o, 1926: 322, fig. 43 ( holotype female from Chile , Valdivia [MNHN 18242a], examined). New Synonymy. Note: Although Nicolet (1849) did not designate any type specimen, most species of Thomisus described by him from Chile were found at MNHN. However, this is not the case with C. edwardsi . Thus, we identify the species by the comparison of several specimens from Valdivia, Chile , with the original description and illustrations provided by Nicolet (1849) .The description shows a female with an abdomen in light colors, trapezoid-shaped, with an arched posterior margin; while the male shows a dark spot in the posterior part of the abdomen and with a sinuous posterior margin [in the original: “...ondulaciones del borde posterior...”]. Spiders with these features were examined and showed no relevant differences regarding their genital features in comparison to other specimens recognized as T. lucasi and T. fuliginosus (species also described by Nicolet 1849 and deposited at MNHN, examined here). We settle the priority of T. edwardsi over T. lucasi , and T. fuliginosus (ICZN 2.4.2.1 and 2.4.2.2.) because the first name was the most used in the literature. Additionally, the synonymy of C. fasciata is also proposed by the absence of significative differences with the Nicolet species. Other material examined.

ARGENTINA : Chubut : Parque Nacional Lago Puelo : Puerto, S 42.097946 ° W 71.620299 ° ( Google Earth ), elev. 210m ( Google Earth ), 15 November 2022 , leg. technical personnel of P. N. Lago Puelo ( MACN-Ar 43771 ) . Diagnosis. Females of C. edwardsi resemble those of C. trapezium sp. nov. , both are the species with the most extreme cases of dorsoventrally compressed habitus of the genus ( Figs 2B , 8B ). Moreover, these two species have robust femora of legs I and II with a pair of apical projections ( Figs 2A , 8A ). However, C. edwardsi can be distinguished from C. trapezium sp. nov. by the epigynal plate with oblique slits (feature that is more similar to what can be observed in C. ditissima ) leading to the copulatory openings, and a flattened MSept ( Fig. 2C ). The copulatory ducts run in two twists before getting to the spermathecae, which present an apical PG ( Fig. 2D ). Males can be easily recognized and distinguished from its congeneric species by the shape of their opisthosoma (with eight tiny posterior projections) ( Fig. 3A ). Their well-developed TRin apical position and long embolus ( Fig. 3C ), are similar to those of the males of C. trapezium sp. nov. ( Fig. 9C ), however, the male palp of C. edwardsi is unique by its conical RTA bearing a short and acute RTAvbr on its basis ( Fig. 3D ). Description. Female (MHNS 840): Anterior eye row recurved and posterior row straight; ALE almost twice as large as the AME ( Figs 2A, B ). Prosoma granulated, with many setiferous tubercles and hyaline setae; light brown, cephalic area and center of the thoracic portion dark brown ( Fig. 2B ). Clypeus bears a pair of central macrosetae on its margin. Sternum brown, scutiform and slightly wider than long. Femora I brown, robust and presenting few setiferous tubercles on its dorsal and prolateral surface; anterior patellae, tibiae, and metatarsi (I and II) predominantly brown, dark brown on their dorsal surface; posterior legs entirely brown. Opisthosoma light brown with a transversal darker line; anterior border slightly concave and posteriorly beveled ( Fig. 2A ). Epigynal plate with copulatory openings preceded by obliquely convergent slits and divided by a wide and flattened MSept ( Fig. 2C ); copulatory ducts wrinkled, membranous and coiled (two twists); spermathecae kidney-shaped bearing a PG ( Fig. 2D ).

Male (CAS 9046659): Anterior eye row recurved and posterior slightly recurved ( Figs 3A, B ). Prosoma and other ocular characteristics as in female. Sternum brown, scutiform and slightly wider than long. Legs I, II and IV predominantly brown, with randomly darker spots; legs III entirely yellow with few brown stains. Opisthosoma as in female, but less widened. Palp with oval cymbium, tegulum with an apical tegular ridge and no apophyses ( Figs 3C, E ); palpal tibia bears three prolateral macrosetae, a short and conical RTAvbr and an acute RTA ( Fig. 3D ).

Distribution. CHILE : Coquimbo , Valparaíso , Santiago , Talca, Bío-Bío , Araucanía , Los Ríos , and Los Lagos , ARGENTINA : Chubut ( Fig. 14A ). Variation. C. edwardsi present a wide range of body coloration, varying from the most common morphotype, which was described above ( Figs 1A, D , 2A ), to specimens fully dark-brown and covered by light-colored setae ( Fig. 1C ). Yellow individuals were also found ( Fig. 1B ) as well as those that are predominantly whitish with sets of brown spots and stripes on their femora, median cephalic area, and opisthosoma ( Fig. 1E ).
