Etymology. The species is named for D.H.B. Maccagnan who collected the type series and continues to add to our knowledge of the Brazilian cicada fauna.
Description. Ground color tawny and green marked with piceous and ferruginous. Green may be tawny in some paratypes.
Head. Head wider than mesonotum, tawny with transverse piceous fascia on posterior head between eyes surrounding lateral ocelli extending anteriorly along lateral portion of median ocellus and epicranial suture terminating anterior to median ocellus, incomplete between lateral ocelli and eyes with tawny mark lateral to lateral ocelli and posterior to median ocellus on epicranial suture, transverse mark complete in some paratypes. Supraantennal plate green, a small piceous mark medially at suture with vertex. Ocelli rosaceous. Eyes testaceous. Head covered with short, silvery pile, longer and more dense posterior to eye. Ventral head piceous except tawny margin of gena along lorum, expanded across posterior gena in some paratypes, covered with short and long silvery pile. Postclypeus with ten transverse grooves, piceous posteroventrally on midline splitting to form a greenish oval on ventral midline extending around apex and narrowing to a line on dorsal surface, the piceous mark expanding onto and covering remaining dorsal surface of postclypeus, lateral regions of ventral side green, tawny or margined laterally with ferruginous in some paratypes. Anteclypeus piceous. Postclypeus and anteclypeus with short and long white pile. Rostrum with green mentum, labium dark castaneous covered with silvery pile, almost reaching hind coxae. Scape, and annulus on proximal pedicel and first flagellar segments tawny, remaining antennal segments castaneous.
Thorax. Dorsal thorax tawny marked with green and piceous. Pronotum with green fascia on dorsal midline expanding laterally on anterior and posterior ends, greenish anterior margin, and pronotal collar. Piceous marks on either side of median green fascia not reaching anterior of fascia, curving along posterior expansion of green fascia and into ambient fissure, curve incomplete in some paratypes, mark in ambient fissure extends across dorsal midline between medial termini of lateral fissures, incomplete or extending through lateral ambient fissure in some paratypes. Mesonotum tawny with piceous submedian and lateral portion of lateral sigillae, remaining lateral sigillae tawny, greenish laterally, between submedian and lateral sigillae and anterior to large triangular piceous mark between anterior arms of cruciform elevation enclosing scutal depressions, cruciform elevation green. Elongated piceous spot on posterolateral mesonotum. Wing groove and metanotum green. Dorsal thorax covered with short silvery pile, longer pile between anterior arms and laterally between arms of cruciform elevation, on posterior mesonotum and along wing grooves. Ventral thoracic segments castaneous medially, green laterally. Ventral segments covered with short and long silvery pile.
Wings. Fore wings and hind wings hyaline, fore wing with eight apical cells, hind wing with six apical cells. Venation green proximally, becoming piceous distally, except piceous anal vein 2 + 3 and piceous mark along anterior basal cell. Infuscation on marginal area extending from terminus of radius anterior 1 around apex of fore wing to apical cell 6. Basal membrane grayish with whitish green base. Hind wing venation green proximally, piceous distally. Proximal vanal fold gray. Infuscation on distal apical cell 2, barely extending onto wing margin posterior to anal cell 1 in some paratypes.
Legs. Legs green and tawny marked with castaneous and piceous, coxae, trochanters and femora with castaneous marks on proximal anterior and medial surfaces, tibiae and tarsi greenish proximally, proportion becoming greater in posterior legs, distal tibiae and tarsus piceous. Fore femora with piceous medial stripe, four castaneous oblique spines, each spine becoming smaller distally and tertiary spine slightly curved. Pretarsal claws, tibial spurs and comb castaneous.
Operculum. Opercula green with piceous spot on lateral base. Curved posterolateral margin and sinuate posterior margin, rounded medial margin and curving anteromedial margin, reaching to abdominal sternite I not covering tympanal cavity. Medial margin extends to medial meracanthus base. Meracathus green with piceous base, extending to posterior margin of operculum. Long silvery pile on operculum surface and radiating from margin. Female operculum green with castaneous spot on lateral base, similarly shaped to but smaller than male operculum, extending medially to middle of meracanthus reaching to middle of tympanal cavity. Female meracanthus colored as in male but extending to posterior of tympanal cavity. Long silvery pile on operculum surface and radiating from margin.
Abdomen. Abdominal tergites castaneous anteriorly, tawny medially and a green posterior margin, auditory capsule piceous, tergites with long silvery pile. Timbal with six ribs, whitish gray with castaneous spot on anterior margin. Sternites similarly colored except castaneous covers majority of sternites. Male sternite VII almost entirely castaneous, sternite VIII castaneous ventrally with tawny dorsal margins covered with long silvery pile. Sternites covered with long and short silvery pile. Female sternites similarly colored. Female sternite VII with a wide, single notch, posterior margin approximately semicircular. Abdominal segment 9 tawny striped with castaneous on dorsolateral surface reaching to stigma and along ventral midline. Dorsal beak tawny, very short, not extending to level of the piceous anal styles.
Genitalia. Male pygofer tawny with small dorsal beak and green fascia on posterior margin between small upper and basal lobes of pygofer. Pygofer basal lobe hooked with pointed termini, curved and rotated slightly toward midline, meeting at midline in some paratypes. Silvery pile on pygofer. Anal styles piceous. Claspers tawny, green on posterior midline at base becoming castaneous along extension that bends towards the midline at an approximate right angle and curves posteriorly to pointed terminus, distal claspers edged in piceous in some paratypes. Additional thin, castaneous extension from base of clasper, straight at base, tapering through an elongated S-shape to terminus. Aedeagus castaneous, tubular, with two spines extending from terminus.
Female gonapophyses IX light castaneous, gonapophyses X and gonocoxites IX castaneous with piceous pile along ventral midline of gonapophysis X giving the appearance of a fascia, covered with radiating golden pile. Ovipositor sheath extending well beyond dorsal beak.
Measurements (mm). N = 4 males or 7 females, mean (range). Length of body: male 11.28 (10.1–12.2), female 14.97 (13.6–15.8); length of fore wing: male 15.12 (14.8–15.5), female 16.04 (15.0–17.2); width of fore wing: male 5.90 (5.8–6.0), female 6.30 (5.8–6.6); length of head: male 1.88 (1.8–1.9), female 2.03 (1.9–2.1); width of head including eyes: male 4.18 (4.0–4.3), female 4.39 (4.2–4.5); width of pronotum including suprahumeral plates: male 4.35 (4.2–4.4), female 4.43 (4.2–4.6); width of mesonotum: male 3.83 (3.8–3.9), female 4.04 (3.8– 4.2).
Diagnosis. This species is very similar in general appearance to T. lanceola n. sp. but has distinctly different male genitalia, particularly the shape of the claspers, which quickly separate male specimens the two species. In addition, the aedeagus lacks terminal spines and the supra-antennal plate of this species joins the postclypeus anterior to the lateral curve rather than at the curve as in T. lanceola n. sp. All species except the small T. minusculus are generally similar in size. The lack of infuscation on the apex of the fore wings of T. maculata, T. misella, T. debruni, and T. demissa n. sp. differentiates them from this new species. The spots and W-shaped mark on the head quickly differentiate T. boulardi and T. egeri, respectively, from this new species. The abdominal tergites have an anterior transverse piceous mark in T. attiguclava n. sp., T. charpentierae, T. nitida, and T. crispula n. sp. that is lacking in this new species. The small medial mark in the ambient fissure on the pronotum distinguishes T. dolabella n. sp. and T. hastifera. The fore wing cubitus anterior arches to touch the median vein near the basal cell of T. cernuunca n. sp. but these veins are separated in T. maccagnani n. sp. Finally, the claspers bifurcate at the terminus, the aedeagus lacks terminal spines and the notch in female sternite VIII has straight lateral margins in T. sauliensis. The male genitalia are distinct from all other species of Taphura as well.
Remarks. The general appearance of this species is very similar to T. lanceola n. sp. and the variability in coloration of the new species makes the male genitalia the simplest way to distinguish the new species. Unfortunately, a female of T. lanceola n. sp. has not been seen to identify a distinguishing character for the female.
Distribution. The species is currently only known from the type series collected in the Brazilian states of Goiás and São Paulo.
