EB2A87E5FFD7FFDE1C233B06FCE0FB3E.taxon	diagnosis	Diagnosis The species of Kryptochroma gen. nov. resemble some of those of Epicadus [e. g., Epicadus caudatus (Mello-Leitão, 1929) and Epicadus tuberculatus (Petrunkevitch, 1910)] by their cryptic bark-dwelling habitus with predominant brown or reddish-brown body coloration, and those of Epicadinus, especially by their small size (varying from approximately three millimeters of the total body length for males and nine to females) and spiny habitus (body covered by many setae and rugose teguments, and opisthosoma bearing stout conical projections) (Fig. 2 A – D). However, they can be easily recognized and distinguished from Epicadus, Epicadinus and other genera of Stephanopinae by the presence of a pair of ventral macrosetae on their anterior patellae (I and II) (Fig. 1 D), sensorial pits (three to five trichobothria surrounded by a small group of duster-shaped setae) on dorsal tibial depressions preceded by a strong plumose macroseta (Fig. 1 C), and a pair of circular taints on the posterior slope of the prosoma (Figs 3 A, 4 A, 7 A). Differently from Epicadinus, the species of Kryptochroma gen. nov. have five opisthosomal projections instead of three, and short leaf-shaped setae covering their entire body instead of long needle-shaped ones (Fig. 1 A – B). Females present a flat epigynal plate, short copulatory ducts and a single pair of oval spermathecae (Fig. 10 C – F); the male palp bears a pear-shaped tegulum with a short and fixed embolus, and a single tipped, stout and conical RTA (Fig. 11 C – F).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFD7FFDE1C233B06FCE0FB3E.taxon	etymology	Etymology The name of the genus is a combination of the Greek words ‘ kryptos ’ (κρυπτός) and ‘ chroma ’ (χρῶμα), which respectively mean ‘ hidden’ and ‘ color’. The name is a reference to the general color pattern of these spiders, which is associated to their cryptic behavior. Gender feminine.	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFD7FFDE1C233B06FCE0FB3E.taxon	description	Description PROSOMA. Granular surfaced due to the presence of spherical setae sockets (Fig. 1 A – B); slightly longer than wide, pear-shaped and usually covered with organic particles. ALE almost two times as large as AME, prosoma coloration shows a gradient of brown and dark-yellow shades (predominantly reddish brown in Kryptochroma hilaris Machado & Teixeira gen. et sp. nov.), lighter on the posterior slope, where there is a pair of rounded spots close to the anterior border of the opisthosoma (Figs 3 A, 4 A, 7 A); in some cases the individual has a yellow longitudinal line between the MS and PME (Figs 3 A, 5 A, 7 A, 9 A). Anterior eye row strongly recurved, AME close to each other, and posterior eye row procurved (Fig. 11 A – B). Clypeus with a central pair of serrated macrosetae (Fig. 1 A). Sternum scutiform, slightly longer than wide in females and as long as wide in males, with brush-shaped setae. Carapace with a conical medianposterior projection pointing backwards (except for K. hilaris gen. et sp. nov. and K. parahybana (Mello- Leitão, 1929) gen. et comb. nov., which have just an obtuse and slight elevation on the top of the thoracic area); opisthosoma short with five stout projections (two lateral pairs and one single and larger terminal projection), anal region and spinneret ring area projected backwards. Mouthparts: chelicerae with five equal-sized teeth; three on the promarginal row and two on the retromarginal. Labium truncated, slightly wider than long. Endites truncated, longer than wide, with scarce promarginal scopula. LEGS. Anterior femora enlarged and bearing many conical setiferous tubercles, legs I and II stouter and longer than legs III and IV, femora I and II with dorsal and dorsolateral stout macrosetae in conical sockets. Tibia I and II with five pairs of ventral macrosetae, metatarsi I and II with three ventral and one dorso-distal pair (Fig. 1 E). Tarsal claws curved, pectinated, unequal in number of teeth (mesial claw with numerous thin teeth and ectal having three stout ones); subungueal tufts scarce, with brush-shaped setae (Fig. 3 B). OPISTHOSOMA. Five short conical projections (two dorsolateral consecutive pairs, and a single caudal one), straight or slightly concave anterior border and rough surfaced, covered by leaf-shaped setae (Fig. 1 B). Anal region and spinneret ring projected backwards, elongated. GENITALIA. Palpus with cymbium and tegulum pear-shaped, without apophyses; RTA single tipped, stout and presenting grooves at the apex (Figs 8 D, 11 D, 13 D). The internal morphology of female genitalia is very conservative, presenting a single pair of reniform spermathecae without any accessory glands or coiled ducts (Figs 3 D, 4 D, 7 D, 10 D, 12 D, 16 D); in ventral view the copulatory openings are excavated in relation to the rest of the surface of the genital area, separated by a septum and located close to the edges of the posterior margin of the epigynal plate (Figs 10 C, 12 C, 16 C).

EB2A87E5FFD7FFDE1C233B06FCE0FB3E.taxon	description	Variations Each one of the color variations documented here (from greyish-green to dark-yellow or predominantly reddish-brown), as well as the stained (e. g., opisthosoma of K. septata sp. nov. – Fig. 16 A) and striped patterns (e. g., prosoma of the specimen in the Fig. 2 A) were observed in all species. Therefore, since all species of Kryptochroma gen. nov. can present any combination of tegument hue, is it virtually impossible to identify them solely based on their color.	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFD2FFD01FA53DC1FD23FD96.taxon	diagnosis	Diagnosis The female of Kryptochroma gigas gen. et sp. nov. resembles those of K. quadrata sp. nov. and K. pentacantha by its large body size, which is significantly larger than in the other species here described. Kryptochroma gigas gen. et sp. nov. can be distinguished by the elevated and short opisthosoma and by the heart-shaped epigynal plate with a short and stout projection over a wide median septum, which divides the median field in two longitudinal gutters reaching the copulatory openings (Figs 3 C – F, 21 A).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFDCFFD31FAC3B5AFDA0F990.taxon	diagnosis	Diagnosis The male of K. hilaris gen. et sp. nov. has a body coloration that resemble that of K. parahybana. However, it can be distinguished by the stouter, shorter and round embolus, which points retro-ventrally (Figs 5 C, E, 20 B). The most striking differences between K. hilaris gen. et sp. nov. and other species of the genus are the discrete MS on prosoma, that is more like an median elevation on the thoracic area (absent in males), and the number of ventral macrosetae on tibiae I and II: while other species have four pairs on each leg for both sexes, in K. hilaris sp. nov. the females bear six ventral macrosetae on tibia I (Fig. 4 A) while males present only five (Fig. 5 A). Females can also be distinguished by the presence of two anterolateral and one median depression on the epigynal plate and by the copulatory openings located in a demilune-shaped concavity delimited by the posterior folds of the tegument (Figs 4 C, E, 21 B).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFD9FFCA1FE43A4EFAD4FD46.taxon	discussion	Note The type series of S. salobrensis is constituted by four syntype individuals of two different species. As the male has remarkable genitalic features and clear diagnostic somatic characters (Fig. 26 A – B), we designate it as lectotype (see the section Additional taxonomic acts). The rest of the specimens in the type series are a juvenile and two adult females of K. parahybana, misidentified (Fig. 26 C – D).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A. (2021): Kryptochroma: a new genus of bark-dwelling crab spiders (Araneae, Thomisidae). European Journal of Taxonomy 778: 26-70, DOI: 10.5852/ejt.2021.778.1565
EB2A87E5FFD9FFCA1FE43A4EFAD4FD46.taxon	diagnosis	Diagnosis The female of K. parahybana resembles that of K. hilaris gen. et sp. nov. by the light median line on prosoma and whitish clypeus (Fig. 7 A); however, it can be distinguished from this latter by the five pairs of ventral macrosetae on the anterior tibiae instead of four, small and elliptical copulatory openings (Figs 7 C, E, 21 C) and epigynal plate lacking the median septum. Males may present a body coloration pattern similar to that of K. hilaris gen. et sp. nov.; however, can be easily differentiated by the shorter abdominal projections (Fig. 8 A – B), reduced RTA with distal indentations (Figs 8 D, F, 20 D) and by the apical and sinuous embolus (Figs 8 C, E, 20 D).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFC6FFCE1FE93BEAFAD4FBB2.taxon	diagnosis	Diagnosis The male of K. pentacantha resembles that of K. quadrata sp. nov. by the shape of the tegulum and embolus (Fig. 11 C, E); however, it can be distinguished by its stout and conical RTA (Figs 11 D, F, 19 A) and larger body size, since they are the largest males of genus, being the sexual size dimorphism in this species less pronounced. Females can be recognized by the external genitalia bearing a noticeable median septum and a pair of long longitudinal depressions leading to the copulatory openings (Figs 10 C, E, 22 A). The most common body color pattern for both males and females usually present a diagnostic median white spot on the dorsum of the opisthosoma (Figs 10 A, 11 A).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFC2FFC11FDE3D7EFDB2FE54.taxon	diagnosis	Diagnosis The male of K. quadrata sp. nov. resembles that of K. pentacantha by the shape and disposition of embolus (Figs 13 C, E, 19 B), however, it can be distinguished from that and other species of the genus by the rounded tegulum, which also presents a retrolateral reentrance, and by the squared-tipped RTA with remarkable grooved surface (Figs 13 D, F, 19 B). The females have an anterior longitudinal ruckle connected to a shallow and convex fold on the epigynal plate, with no median outgrowth, gutters or septum separating the copulatory openings (Figs 12 C, E, 22 B).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFCDFFC31F363B18FB7AFB39.taxon	discussion	Notes According to Keyserling (1880), the description of the species in his work was based on the holotype originally proposed by Taczanowski (1872), from Cayenne (French Guiana), which is presumably lost. We had access to a specimen from the Natural History Museum of London (BMNH 1890.7.1.3479) that is labeled as “ type ” (Fig. 14 G – H); however, it is clearly not the holotype because it was collected after the original description. Since this specimen is strikingly similar to the one represented in the original illustrations (where the author highlighted the diagnostic features of the male palpus: sinuous RTA and the tip-narrowed tegulum) and was found near the original locality (New Granada, currently corresponding to the Colombian territory), we propose it as the neotype for K. quinquetuberculata comb. nov. (Fig. 14 G – H).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFCDFFC31F363B18FB7AFB39.taxon	diagnosis	Diagnosis The male of K. quinquetuberculata resembles that of K. pentacantha by its stout opisthosomal projections and by the presence of a dorsal white macula on the opisthosoma (Fig. 14 A). However, it can be recognized by the tegulum in the shape of a water drop, bearing a straight and tip-narrowed embolus instead of a curved termination observed in its closest correlated species (Figs 14 C, E, 19 C). Moreover, K. quinquetuberculata has a remarkable RTA which is large at the basis, sharpen abruptly at the tip, and sinuous, pointing towards to the dorsum of the cymbium (Figs 14 D, F, 19 C).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFC9FFFD1FD038C5FB26FECB.taxon	diagnosis	Diagnosis The female of K. septata sp. nov. is similar to that of K. pentacantha by its general body shape, prominent MS and well-developed median opisthosomal projection. However, females of K. septata sp. nov. can be recognized by the large median septum on the epigynal plate and by the deep excavations where the elliptical copulatory openings are located (Figs 16 C, E, 22 C). The male is similar to that of S. quadrata sp. nov. by the rounded tegulum and to K. pentacantha by the stout and conical RTA, however, can be distinguished from these two species by its shorter, thicker and more curved embolus (Figs 17 C, E, 20 A). Differently from K. pentacantha, in males of K. septata sp. nov. the RTA presents a terminal curvature that makes this apophysis points vertically rather to the backwards of the cymbium (Figs 17 D, F, 20 A).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

The following species do not share the diagnostic characters proposed for Kryptochroma gen. nov., therefore. they are being considered as nomina dubia or transferred to other genera recently revised by Teixeira et al. (2014), Silva-Moreira & Machado (2016) and Machado et al. (2018, 2019 a).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFFCFFF01F803BDFFC7CFA68.taxon	discussion	Note Although the holotype described by Walckenaer (1837) is presumably lost, and the “ conspecific ” and sympatric specimen used by Keyserling (1880) to describe S. stelloides had not been found, the original descriptions and illustrations (Fig. 27 C – D) allowed us to unequivocally identify this species as conspecific with Epicadus caudatus (Fig. 27 A – B), a species that was recently examined and revised by Machado et al. (2015, 2017). Following the priority principle, we transfer Stephanopis stelloides to Epicadus and propose the name E. stelloides comb. nov. as a senior synonym over E. caudatus (Fig. 27). Thus, based on the images provided by Machado et al. (2015), we also recognize the identity of the male specimen of S. salobrensis as conspecific to E. stelloides comb. nov.	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.

EB2A87E5FFFCFFF01FA13810FB2BFD2C.taxon	discussion	Note This species lacks the typical cheliceral teeth that are still considered as a diagnostic feature for Stephanopinae. Instead, its elongated labium and peglike-setae on endites (see Teixeira et al. 2014) allow us to undoubtedly consider this spider as an Aphantochilinae. We propose the transfer of S. quimiliensis to Ulocymus Simon, 1866 based on the presence of stout and conical projections on the dorsum of the carapace (see Teixeira et al. 2014) and shape of the copulatory structures (Fig. 25).	en	Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J., Teixeira, Renato A.
