03A9E109FF932F37FE55B8C8FDE1FD32.taxon	description	Description The genus Cyriocosmus comprises small to medium-sized spiders, with total length 10 – 32 mm, excluding chelicerae and spinnerets. Carapace oval, uniformly coloured or with bicoloured pattern. Caput moderately domed. Eye tubercle oval, flattened, distinctly wider than longer, with eight eyes, anterior eye row slightly procurved, posterior row slightly recurved in dorsal view, a group of strong setae present on the median anterior margin of the tubercle. Clypeus absent to very narrow. Fovea transverse, straight to slightly procurved. Chelicerae without rastellum and stridulatory bristles, with teeth on promargin (7 – 10), first basal teeth are complemented with granulation. Labium domed, wider than longer, with 30 – 100 cuspules in anterior third, maxillae with 100 – 360 cuspules in basal half on ventral side, maxillary lobe pronounced into conical process. Variability in number of labial and maxillary cuspules in Cyriocosmus perezmilesi was described by Kaderka (2010). Labiosternal groove distinct, shallow and flat, with two slightly separate or joined elongated sigilla. Sternum oval, with three pairs of small, oval sigilla located near coxae III, coxae II and coxae I, posteriorly separated from the margin approximately by their own diameter. Legs uniformly hirsute, with (Figures 12 b, 17 b, 34) or without (Figures 1 b, 7) whitish or yellowish longitudinal striation on dorsal side. Leg pattern (from longest to shortest): I> IV> II> III in Cyriocosmus ritae or IV> I> II> III in all congeners. Leg segments: generally uniform to slightly incrassate on femur III. Incrassate tibia I is present in males of C. ritae only (Figure 24 b). Dense scopulae on ventral side of all tarsi, metatarsi partly scopulate, scopulae more extended on anterior than on posterior legs. Tarsal scopulae I, II usually undivided, on tarsi III, IV usually divided by longitudinal band of setae. Retrolateral side of femur IV and prolateral side of femur I without pad of plumose setae. Maxillary and trochanteral stridulatory setae or bristles absent. Spination as in species descriptions. Dorsal side of all tarsi with two irregular longitudinal rows of very short claviform trichobothria. Paired tarsal claws without teeth, third claw absent in all tarsi. Claw tufts dense, bilobate, present on all tarsi. Abdomen uniformly coloured (Figures 1 b, 7) or with lateral stripes (Figures 12 b, 16 c, 17 b, 34). Urticating setae of type III (Kaderka 2010, figure 13) with very short reversed barbs are located in central semicircular (Figure 13 d) to U-shaped glossy patch (Figures 17 b, 34). Abdomen ventrally with (Figures 16 e, 23 d) or without dark longitudinal band. Four spinnerets present. PLS composed of three digitiform segments. PMS digitiform, mono-segmented.

Two unequal tibial apophyses are present on tibia I (Figures 27, 28): a longer retrolateral tibial apophysis, usually with short apical spine and a shorter prolateral tibial apophysis usually with single, well-developed retrolateral spine at base. Metatarsus I not sigmoidly curved, without basal or median protuberance on retrolateral face, except the males of C. ritae having a median protuberance (Figure 24 b). Male metatarsus I flexion between both tibial apophyses, except C. fernandoi and C. versicolor with flexion on retrolateral side of retrolateral tibial apophysis, C. pribiki on retrolateral tibial apophysis and C. ritae with flexion on prolateral tibial apophysis.

03A9E109FFB22F1AFE3BBF0FFCB9FC7A.taxon	diagnosis	Diagnosis Cyriocosmus nicholausgordoni sp. nov. can be distinguished from all other congeners, except C. leetzi Vol, 1999, by its reddish-brown carapace with the black caput and seven radially arranged black spots in the thoracic area, and by the presence of the dark longitudinal ventral band. Males have short paraembolic apophysis and weakly developed prolateral superior keel in palpal bulb morphology, female spermathecae have a caliciform extension and convex basal plates. From C. leetzi it differs by the black femora without whitish longitudinal stripes on the dorsal face and the presence of the fourth pair of very narrow lateral stripes near spinnerets. Males also differ by the absence of retrolateral process in palpal tibia, instead there is only a cluster of numerous spiniform setae.	en	Kaderka, Radan (2015): The Neotropical genus Cyriocosmus Simon, 1903 and new species from Peru, Brazil and Venezuela (Araneae: Theraphosidae: Theraphosinae).

03A9E109FFBB2F1EFE23B817FDCBF9C1.taxon	diagnosis	Diagnosis The species can be distinguished from all other congeners by lacking the striped pattern on dorsal abdomen (Figure 21 c) and by the black carapace with two pale and wide lateral stripes (Figure 21 a), in combination with the yellowish longitudinal stripes on the dorsal face of the legs in females.

Notes All types are uniformly light brown due to the long-term preservation in alcohol. Simon (1889) mentioned in the original description that females of C. sellatus have yellowish longitudinal stripes on the dorsal faces of the legs and pointed out the presence of two pale and wide lateral stripes on the carapace as well. These traits are newly included in the diagnosis. It is supposed that the yellowish longitudinal stripes are present in males as well and are obviously much more distinct, as in males of other species with pale longitudinal stripes on the legs.	en	Kaderka, Radan (2015): The Neotropical genus Cyriocosmus Simon, 1903 and new species from Peru, Brazil and Venezuela (Araneae: Theraphosidae: Theraphosinae).

The variability in the length of the carapace, the number and the arrangement of the cheliceral teeth, the number of labial and maxillary cuspules, the leg pattern and the spination of tibial apophyses is shown in Table 3. Coloration during ontogeny Carapace light brown, with a dark caput and surrounding of fovea, abdomen black, with three light brown lateral stripes, basally joined, and two short stripes near spinnerets, not basally joined, dorsally with a light brown, U-shaped patch of urticating setae. Femora and tarsi black, patellae, tibiae and metatarsi light brown.	en	Kaderka, Radan (2015): The Neotropical genus Cyriocosmus Simon, 1903 and new species from Peru, Brazil and Venezuela (Araneae: Theraphosidae: Theraphosinae).

03A9E109FFAC2F0FFE7CBFCEFDEDFDFE.taxon	diagnosis	Diagnosis Differs from all other congeners, except C. nicholausgordoni sp. nov., by its reddishbrown carapace with the black caput and seven radially arranged black spots in the thoracic area, and by the presence of the dark longitudinal ventral band. From C. nicholausgordoni sp. nov. it differs by the black femora with whitish longitudinal stripes on the dorsal face. Males also differ by the presence of the retrolateral process in palpal tibia with a cluster of numerous spiniform setae (Figure 18 e).	en	Kaderka, Radan (2015): The Neotropical genus Cyriocosmus Simon, 1903 and new species from Peru, Brazil and Venezuela (Araneae: Theraphosidae: Theraphosinae).
