Labium with a smaLL median scLerotized part of the LiguLa (arrows in Figs. 9 View FIGURES 4–13 , 18 View FIGURES 14–22 ); LabiaL paLpus 3 segmented, articLe 1 the Longest and widest, articLe 2 wider and shorter than 3. Mentum with anterior margin strongLy arcuate ( Fig. 9 View FIGURES 4–13 ). GuLar pLate narrow, the narrowest on the apicaL third-fourths ( Fig. 6 View FIGURES 4–13 ).

Female. SimiLar to maLe, eXcept of posterior margin of sternite 7 Less broadLy emarginate ( Fig. 30 View FIGURES 23–33 ); sternite 8 with anterior margin weakLy scLerotized and posterior margin truncate to sLightLy emarginate ( Fig. 30 View FIGURES 23–33 ); tergite 9 without ventraL struts ( Fig. 31 View FIGURES 23–33 ); sternite 9 consisting of pair of hemisternites, each 4X as Long as wide ( Fig. 32 View FIGURES 23–33 ); spermatheca smaLL with capsuLe of subsphericaL shape ( Fig. 33 View FIGURES 23–33 ).

Geographical records. The species is known onLy from the type LocaLity, an area of canga surrounded by Amazon Forest , at the LocaLity of Carajás, municipaLity of Parauapebas, Pará, BraziL ( Fig. 64 View FIGURES64–69.64 ).

Host termites. This species was found in epigeaL nests of Nasutitermes sp. ( Fig. 65 View FIGURES64–69.64 ). The termites are deposited in the FederaL University of Viçosa (UFV), Viçosa, BraziL, under the foLLowing numbers: 8009, 8011, 8014 and 8015.

Biological Notes. ALL specimens were coLLected inside of termite nests in an area of canga, an area with high concentration of iron ore in the Amazon forest ( Skirycz et al. 2014). The area, where the epigeaL nests were coLLected, is characterized by an open pLant formation with grasses over canga, sometimes fLooded or with Velozia sp. ( VeLLoziaceae ). The specimens of Termitomorpha sinuosa sp. nov. were found disperssed inside of the nests (center and base of nests that are corresponding to numbers 8009, 8011 and 8014, and mostLy in the base in 8015). Some specimens of T. sinuosa sp. nov. were observed with the termites for a few minutes by the third author (C.S. Rosa). When the nest was broken, the specimens of T. sinuosa sp. nov. run among the nymphs and workers of termites without any sign of aggression between them ( Fig. 66 View FIGURES64–69.64 ). Whenever they met, paLpation of the rove beetLes by the termites was observed. So, because of the harmonious nature of the beetLe-termite interactions, its possibLe to infer that the T. sinuosa sp. nov. was weLL-integrated into the sociaL Life of the coLony.

Etymology. The specific name " sinuosa " is a Latin adjective that means "fuLL of bending", because the sinuous LateraL margins of pronotum. The adjective is of feminine gender agreeing with the gender of the genus.
