Type material. Holotype male (No. E002/2004) (mounted on pin, genitalia on slides with same number), Ecuador east, Orellana distr., Yasuni N.P., 00°40'28"S; 76°23'51"W, 230 m a.s.l., primary rainforest, 14–21 March 2004, M. Kozánek & M. Labuda leg., deposited in the collection of the Institute of Zoology SAS, Bratislava, Slovakia.

Description. Medium size species. General colour of body yellowish white with ornamental drawing on pronotum and tegmina ( Fig. 1 a).

Head with reddish brown narrow vertex. Frons, clypeus, labrum and genae pale yellow with darker lunate spots above antennal sockets. Eyes dark brown with distinct facet surface, ocellar spots (fenestrae) present, but inconspicuous ( Fig. 1 c). Antennae relatively thick, shorter than body, annulate; scapus, pedicel and first joint of flagellum brown, following 35 joints black, 10 joints white, 8 joints black and final four preserved joints white (flagellae are not complete). Maxillary palps yellowish, first joint very small, second joint shorter as remaining three, last joint depressed. Labial palps three-jointed, pale yellowish.

Pronotum widest in caudal third, anterior margin rounded, posterior margin towards centre angulate convex; central part pale yellow, lateral margins narrowly reddish brown lined with black lines ( Fig. 1 a, b). Tegmina and wings fully developed, folded and overlapping apex of abdomen. Almost whole surface of tegmina nearly white with delicate bluish tinge. Nearly whole costal margin of tegmina with narrow reddish brown band lined with black line, which expand along the radial branches into radial field. Anal fields of forewings distinct with dense network of cross veins, medial branches obviously cross-connected. Legs yellow, relatively short. Tarsal joints with small pulvilli. Tarsal claws symmetrical, inner side subtly serrated, between claws small but distinct arolium. Anteroventral margin of front femur ( Fig. 2 a) armed only with delicate spines: 11 longer and sparse, 26 shorter and dense—type C0 (sensu Bey-Bienko 1950 and Roth 2003). Antero-ventral margin of hind femur only with small inconspicuous spines ( Fig. 2 b).

Abdomen with unspecialized dorsal surface. Supra-anal plate short, posterior margin rounded, shallowly emarginated in the middle ( Figs. 1 d, e, g). Two small, but distinct, strongly sclerotized thorn-like apex of paraprocts present in the middle part of supra-anal plate ( Fig. 3 a). Cerci short, composed of 10 separated segments ( Figs. 1 d, e, g). Subgenital plate nearly symmetrical, rounded. Styli very long, symmetrical ( Figs. 1 d, e, f). The phallomere L1 (R sensu Klass 1997) is distinctly sclerotized, bifurcate ( Fig. 3 b). Phallomeres L2vm (L2 sensu Klass 1997) and R2 (L3 sensu Klass 1997) are not present.

Measurements. Holotype ♂ (mm): total length 17.4, length of body (without tegmina) 14.5, length of pronotum 3.9, width of pronotum 4.7, length of tegmen 13.8, width of tegmen 4.0.

Etymology. This new cockroach species is named in honour of Milan Kozánek, a well-known entomologist and one of the collectors of type specimen.

Differential diagnosis. Panchlora kozaneki is by coloration most similar to P. pulchella and P. signata Brunner von Wattenwyl, 1897 , but it differs in a white pronotum and tegmen with reddish brown margins. P. kozaneki is very similar to P. serrana Rocha e Silva, 1958 by the form of supra-anal and subgenital plates and the phallomere L1. However, coloration of these two species is different— P. serrana have lateral margins of pronotum hyaline and tegmen hyaline with black dots disperse at the whole surface.
