I found the keys on net from A revision of Tecoma Juss. (Bignoniaceae) in
Bolivia
<http://redbiblio.unne.edu.ar/pdf/62_WOOD%202008%20A%20revision%20of%20Tecoma.pdf>
by JRI Wood (Botanical Journal of the Linnean Society, 2008, 156, 143–172)
as below:
*KEY TO TECOMA SPECIES IN BOLIVIA*
1. Corolla yellow (sometimes with reddish veins), ventricose above a
shortly cylindrical, strongly demarcated base, ±campanulate in form;
anthers sparsely pilose ......2
1a. Corolla red, red and yellow, or orange (very rarely yellow), gradually
widened from the base, ±cylindrical-tubular in form; anthers glabrous
........3
2. Leaves simple; corolla completely glabrous externally ...........1. *Tecoma
beckii*
2a. Leaves five- to nine-foliolate; corolla usually with a few hairs, at
least in the sinuses of the lobes .............2. *Tecoma stans*
3. Corolla regularly five-lobed, uniformly red or reddish-orange (very
rarely yellow); anthers included; leaflets ovate to elliptic,
serrate-dentate ..........4. *Tecoma tenuiflora*

*KEY TO SUBSPECIS OF TECOMA FULVA*
1. Leaves hirtellous; leaflets 11–21, broadly obovate, about as broad as
long, mostly < 1 cm long.........a ssp. *fulva*
1a. *Leaves glabrous or, if hirtellous, the terminal leaflet oblong, > 1.5
cm long, much longer than broad; leaflets 1–17 *.........2
2. *Leaf rhachis clearly winged; lateral leaflets obovate to oblanceolate,
two to three times as long as broad*; corolla regularly expanded from base,
lacking a clearly differentiated basal tube, lobes < 7 mm long, the dorsal
pair not united or united for < 2 mm; stamens at mouth of corolla, the
filaments equal in length .........3
2a. Leaf rhachis unwinged or almost so; all leaflets oblong or oblong
lanceolate, broadest near the centre or below, mostly three to five times
as long as broad; corolla with a clearly differentiated basal tube, the
lobes c. 10 mm long, the dorsal pair united for > 2 mm; two outer filaments
longer than the inner pair, their anthers exserted .......5
3. Leaflets 13–17, coriaceous; the terminal leaflet only slightly larger
than the laterals, obovate ................b. ssp. *arequipensis*
3a. *Leaflets 1–9(-11), thin in texture, the terminal leaflet much larger
than the laterals, oblong *..................4
4. Leaflets 1–7 (i.e. some leaves simple); branchlets and leaves hirtellous
.................c. ssp. *tanaeciiflora*
4a.* Leaflets 3–9(-11), the leaves always divided into leaflets; branchlets
and leaves glabrous or almost so *................. d. ssp. *guarume*
5. Corolla 5–7 cm long; leaflets conspicuously serrate-dentate, teeth c.
seven per centimetre ...... e. ssp. *altoandina*
5a. Corolla 4.5–5.5 cm long; leaflets weakly toothed, teeth three to four
per centimetre..................f. ssp. *garrocha*

It is very difficult to see many details with your very small images.
However, Leaf rachis appears to be winged and I see 7 leaflets. So
ssp. *guarume
*is possible.
Pl. check the above keys in detail.

It appears close to images of ssp. *guarume *seen at TechieOldFox
<https://techieoldfox.wordpress.com/2016/05/17/tecoma-fulva-ssp-guarume/> and
Flora and fauna website
<https://www.nparks.gov.sg/florafaunaweb/flora/6/6/6684>, but looks
different from those at Kew Database
<https://www.kew.org/science/tropamerica/imagedatabase/large198/cat_single198-94.htm>
