Studies on Brazilian Pseudophasmatidae (Phasmatodea) with the description of a new species of Agrostia Redtenbacher and new records for Metriophasma Uvarov and Parastratocles Redtenbacher Author Heleodoro, Raphael Aquino Author Mendes, Diego Matheus de Mello Author Rafael, José Albertino text Revista Brasileira de Entomologia 2017 2017-03-24 61 2 170 177 http://dx.doi.org/10.1016/j.rbe.2017.03.003 journal article 10.1016/j.rbe.2017.03.003 1806-9665 13195539 Parastratocles multilineatus ( Rehn, 1904 ) ( Figs. 27–31 ) Comments. This species is recognized by the yellow spot on the anal area of the alae ( Figs. 27 and 28 ). Coloration on living insects can vary significantly from specimens known from Costa Rica . The original coloration is nearly completely lost after drying process, turning it mostly dark yellow and black ( Fig. 28 ). Characters on female terminalia are only available from Rehn (1904) and Redtenbacher (1906) , with limited information and without illustrations. Due to this, we characterize the female terminalia based on specimen from Rondônia , Brazil . Description ♀ terminalia . Terga 8–10 dorsally with median longitudinal black stripe ( Figs. 28 and 29 ). Terga 8–9 rectangular in dorsal view, trapezoidal in lateral view, all margins straight ( Figs. 29 and 30 ). Tergum 10 with anterior margin straight, slightly 1.

Subgenital plate densely setose, with median longitudinal dark brown carina; sword shaped, narrowing near the posterior margin; apex oblong, being 1.4 times longer than tergum 9 ( Fig. 31 ). Cercus conical, covered by setae, with oblong apex. Biological information. The specimen was found in an ombrophilous Terra Firme Amazonian Forest, on bushes of approximately 1.6 m high. When stressed, the insect opened its wings, making the aposematic coloration more visible. Furthermore, it also sprayed a strongly stinky (resembling an herbaceous smell) substance.

Xerosomatinae : Prexaspini Metriophasma (Metriophasma) diocles ( Westwood, 1859 ) ( Figs. 32–36 ) Comments. This species is easily distinguished by having blue spots near base of the alae ( Fig. 33 ). We recorded two coloration patterns for this species: one with body mainly light yellow ( Figs. 32, 33 , 36 ) and another mainly dark brown ( Figs. 34 and 35 ). Biological records. D. M. M. Mendes took photos from the lighter phenotype ( Figs. 32 and 33 ) in 2013, at an ombrophilous Terra Firme Amazonian Forest in Amazonas State ( AM , Brazil ), but did not collect the specimen. This year, the same author found different specimens of same species in Acre State ( AC , Brazil ) with lighter and darker phenotypes ( Figs. 34–36 ) in an ombrophilous Terra Firme Amazonian Forest with bamboos, and collected two females and one male specimen . Both populations (AC/AM) were found on bushes, approximately between 1.4 and 2.0 m high. When resting, these insects conceal their presence with a camouflage behavior similar to members of Prisopodidae , which consists of joining all legs near to its body to decrease body width ( Fig. 36 ). When stressed, this species performed an agonistic display by opening and closing their wings repeatedly showing the blue and black spots on wings, possibly confusing a potential predator.
