(Figs. 1–33, 64–66)
Type material. HoLotype: maLe (photo, Figs. 1–3), deposited in DZUP,: " BRASIL, PA,/ Parauapebas/Carajás, in/ Nasutitermes /sp., 19–III–2010,/C.S. Rosa (Leg.)", " HOLOTYPE / Termitomorpha sinuosa /Caron, BortoLuzzi & Rosa". Fifteen paratypes, in aLcohoL 70% (eXcept two pinned), four in DZUP and seven in FMNH, with the same LabeLs of hoLotype; and three in DZUP (one in pinned microviaL with gLycerin and partiaLLy dissected) and one in FMNH (in pinned microviaL with gLycerin and partiaLLy dissected), with the same LabeLs of hoLotype eXcept " 21– III–2010 ".
Diagnosis. Termitomorpha sinuosa sp. nov. differs from T. manni (Seevers, 1946) by the antennaL articLes 6– 10 cLearLy decreasing in Length, anterior margin of cLypeus feebLy emarginate and sinuous LateraL margins of pronotum.
Description. Male. MaXimum body Length: 5.0 mm; maXimum eLytraL width: 0.8 mm. Head, pronotum and eLytra somewhat red-brown to dark-brown (Figs. 1–2), abdomen yeLLowish to Light brown with segments 3 to 5 Lighter than 6 to 8 and Large membranous areas between segments 2–3, 3–4, 4–5 and 5–6; appendices uniformLy Light brown. DorsaL surface of head, pronotum and eLytra gLossy with sparse setigerous pores. Head subQuadrate (Fig. 4). Eyes sLightLy shorter than tempLes. Antenna strongLy genicuLate (Fig. 7); articLe 1 nearLy the Length of 2–5 combined, somewhat compressed at the base; articLe 2 sLightLy Longer than 3; 3 one-fourths Longer than 4; 4 sLightLy Longer than 5; articLes 6–10 cLearing decreasing in Length; articLe 11 nearLy the Length of 9–10 combined and pair of coeLoconic sensiLLa (Figs. 7, 17). CLypeus with a Low and smooth eLevation (Fig. 5) and then decLivous; anterior margin feebLy emarginate (Fig. 4). Labrum with anterior margin sLightLy emarginate (Fig. 8). MandibLes nearLy symmetricaL; each broad, with smaLL subapicaL tooth and huge membranous prostheca (Figs. 10, 19). MaXiLLa with gaLea narrower than Lacinia (Figs. 14–15); gaLea and Lacinia curved on the same direction; apeX of Lacinia with a prominent sinuous spine-Like; maXiLLary paLpus 4 segmented, articLe 2 the Longest, 3 subgLobose, the widest and somewhat concave on internaL face (Fig. 16), articLe 4 subuLate. Labium with a smaLL median scLerotized part of the LiguLa (arrows in Figs. 9, 18); 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). GuLar pLate narrow, the narrowest on the apicaL third-fourths (Fig. 6). Pronotum somewhat wider than Long (Fig. 11); strongLy conveX; somewhat sinuous on LateraL margins; posterior margin broadLy arcuate and sLightLy notched at the middLe. ELytra feebLy narrowing to the apeX (Fig. 12); each with acute tooth at the anteromesiaL border in internaL view, tooth Long and somewhat scaLed (arrows in Figs. 12, 20). Hind wings not deveLoped (brachypterous). TarsaL formuLa 5–5–5; tarsomere 1 the Longest; tarsomeres 4 and 5 aLmost fused (Fig. 13); protibia with microsetae on aLmost internaL margin (Fig. 13). Abdomen physogastric, aLmost two times wider than eLytra and the maXimum width on segment 5; anterior margin of tergite 7 with conspicuous gLanduLar area, continuous at the middLe (Figs. 21–23); posterior margin of sternite 7 strongLy emarginate (Fig. 24); posterior margin of tergite 8 truncate to sLightLy emarginate; posterior margin of sternite 8 strongLy emarginate (Fig. 25); tergite 9, each LateraL piece separated by tergite 10 and with robust and eLongate ventraL struts (Fig. 26); sternite 9 sLender, eLongate and curved dorsaLLy to apeX (Fig. 27); posterior margin of tergite 10 rounded. Aedeagus about two-thirds of the Length of abdomen; median Lobe with nearLy buLbous base and apeX acute (Fig. 29); and parameres weLL-deveLoped and foLLow the aLeocharine pattern (Fig. 28).
Female. SimiLar to maLe, eXcept of posterior margin of sternite 7 Less broadLy emarginate (Fig. 30); sternite 8 with anterior margin weakLy scLerotized and posterior margin truncate to sLightLy emarginate (Fig. 30); tergite 9 without ventraL struts (Fig. 31); sternite 9 consisting of pair of hemisternites, each 4X as Long as wide (Fig. 32); spermatheca smaLL with capsuLe of subsphericaL shape (Fig. 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).
Host termites. This species was found in epigeaL nests of Nasutitermes sp. (Fig. 65). 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). 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.
