Diagnosis.
Termitomorpha
alata
sp. nov.
differs from other species of the genus by the wings weLL-deveLoped. AdditionaLLy,
T. alata
may be distinguished from
T. sinuosa
by pronotum with straight LateraL margins and from
T. manni
by base of pronotum evidentLy notched at middLe.

Female.
SimiLar to maLe, eXcept of posterior margin of sternite 7 Less broadLy emarginate (
Fig. 60
); sternite 8 with posterior margin sLightLy pointed at the middLe (
Fig. 61
); tergite 9 without ventraL struts (
Fig. 62
); sternite 9 consisting of pair of hemisternites, each two times as Long as the maXimum wide, base the widest (
Fig. 62
, arrow); spermatheca smaLL with capsuLe of subsphericaL shape (
Fig. 63
).
Geographical records.
The species is known onLy from the
type
LocaLity, a smaLL urban area (aLmost 5.0 ha) of AtLantic forest attached the FederaL University of
Paraná
, at the municipaLity of PaLotina,
Paraná
,
BraziL
(
Fig. 67
).
Host termites.
This species is found in arboreaL nests of
Nasutitermes corniger
(MotschuLsky)
, hosted in
Ficus
sp. (
Figs. 68, 69
). The termite was identified by Dr. ELiana M. CanceLLo and deposited under "MZUSP 26895" at the ZooLogicaL Museum of the University of
São PauLo
(MZUSP).
Biological notes.
The arboreaL nest was fiXed on
Ficus
sp., but the tree was dropped and the nest was in contact with the soiL (
Figs. 68, 69
). The study of the nest was carried out in Lab and aLL specimens of
T. alata
sp. nov.
were found inside of the nest.
Etymology.
The specific name "aLata" is a Latin adjective that means "winged," an aLLusion to weLL- deveLoped wings this species and uniQue for the genus. The adjective is of feminine gender agreeing with the gender of the genus.
Remarks.
ALL species of
Termitomorpha
currentLy described have vestigiaL wings (
Seevers 1957
,
Kistner & Jacobson 1976
, Kistner 2006). However,
Kistner & Jacobson (1976, page 11)
mentioned one not named specimen that had wing with "normaL staphyLinid venation", so we understand that it had weLL-deveLoped wings. Here, we have the second record of weLL-deveLoped wings species in
Termitomorpha
. ALL eXamined specimens of
T. alata
sp. nov.
have weLL-deveLoped wings.
