( Fig. 1 A – M ) Diagnosis . Pronotum black, without maculae, covered with short yellowish-gray appressed pubescence, and dense, long, erect black setae; anterior impression wide and shallow, posterior impression wide and deep; umbone moderately elevated, slightly convex, almost flat on top, sides unpunctate and glabrous, central area with dense, long, erect black setae, with shorter setae interspersed, separated from basal impression by a shallow sulcus. Each elytron with large, subrounded black macula on middle of anterior two-thirds; posterior third black, with its anterior margin straight or projected toward anterior region along suture, and may or may not reach the anterior black macula. Female with ventrite 5 not depressed. Holotype male . Form moderate-sized, slightly robust, length from clypeal apex to pygidium apex, 9.5 mm ; width across humeri, 3.0 mm; integument with dense, appressed yellowish-gray pubescence and moderately sparse, long, erect, black setae. Coloration . Body black, with elytra mostly red, mandibles and labrum dark brown. Head slightly narrower than pronotum; pubescence slightly denser on genae, frons, and clypeus. Vertex with slightly dense and moderately coarse punctures. Frons transverse, three times wider than lower eye lobe, slightly convex; genae subquadrate, length subequal to lower eye lobe; maxillary palpi with apical segments slightly enlarged, narrowly ovoid; mandibles with basal half strongly excavated, apical half glabrous, moderately arcuate; labrum densely fringed with both short and long erect golden setae; eyes moderately large, very finely faceted, upper lobes slightly closer to each other than lower lobes; antennae shorter than body, all segments with fairly denser and slightly thicker yellowish-gray pubescence beneath; from scape to third segment with fairly dense, moderately coarse punctures, with long, suberect black setae; from fourth to tenth segment with a fringe of long, erect, black setae directed downward and inward; third segment shorter than scape; fourth shorter than third; fifth subequal to fourth; sixth shorter than fifth; sixth subequal to seventh; segments eighth to tenth gradually diminishing in length; eleventh longer than tenth and subacute apically. Pronotum wider than long; sides slightly rounded; densely, coarsely punctate; with long erect setae sparser than on umbone; anterior impression wide, shallow, posterior impression broad, deep; posterior margin with fringe of dense, very long, erect black setae (sparser and shorter toward sides); umbone large, slightly convex, moderately elevated, sides delimited, glabrous, central area coarsely, contiguously punctate, with dense, both long and short erect black setae, lacking pubescence, sides without maculae, delimited posteriorly by a fairly shallow sulcus between umbone and basal impression. Prosternum narrow, shallowly impressed, micropunctate; prosternal process very narrow. Meso- and metaventrite micropunctate; metepisterna moderately elevated on middle. Scutellum widely rounded apically, slightly transverse, micropunctate, covered with dense, short, erect black setae. Elytra about twice as long as wide, parallel-sided; subaligned punctate, punctures on basal half moderately dense, slightly coarser, becoming finer, shallower and sparser toward apex from middle; erect setae longer on circum-scutellar region and gradually decreasing in size and density outward; humeri with a dark macula; basal half with a large black macula on each elytron, almost reaching suture, macula densely clothed with short, erect, black setae; apical third black, anterior margin of black region expanding suturally towards large maculae (reaching and partially surrounding them), without maculae; apices rounded. Legs short, stout, micropunctate; apical half of mesotibiae with brush of short black setae dorsally; apical fifth of metatibiae with shorter and sparser bristly black setae dorsally.

This species differs from T . ineditus by the larger anterior black macula, narrower black area of the elytra, the lack of maculae on anterior edge of this area, and the sparser ventral yellowish-gray pubescence. It differs from T . paracomes and T . comes by the subaligned punctate elytra, anterior margin of the black area of the elytra without black elongate macula (present in T. paracomes and T. comes ), and not inclined backward close to suture (directed backward in T. paracomes and T. comes ); it also lacks the yellowish-gray pubescence on the umbone (present in T . comes ), and ventrite 5 of females without depression (present in T . paracomes ). It differs from T . cleroides Thomson, 1860 by the elytra with the anterior black macula distinctly larger, anterior margin of the black area of the elytra lacking black macula (present in T. cleroides ), and not inclined backward close to suture (directed backward in T. cleroides ), and the absence of yellowish-gray pubescence on the umbone (present in T. cleroides ). The new species was found associated with an asclepiad vine, Dictyanthus yucatanensis Standl. ( Fig. 1 N – P ), endemic to the Peninsula of Yucatán. All specimens of the new species were collected between July 30 and August 22 , on two flowering and one vegetative individuals of this asclepiad vine located approximately 130 to 240 m apart from each other. Other species of Apocynaceae vines were growing in the area but we did not find individuals of the new species on any of them. The area of the type locality is under high human pressure due to the expansion of residential developments around the state’s capital city and nearby beaches. The seasonally dry tropical forest is quickly being replaced by housing for people seeking the famous public safety and peaceful living conditions of the state of Yucatán. Some areas with remnants of forests have been preserved as parks; however, these areas are frequently trimmed to reduce the herbaceous layer to a height of approximately 10 cm above ground level. Furthermore, these parks serve as illegal dumping grounds and sources of wood, firewood, and soil. By the time of submission of this work, two out of three of the host plants were already trimmed to an approximately 20 cm long portion of its semi-decumbent woody stem and died shortly afterwards. Etymology . The Latin specific epithet “ paradisi ” means “of the park” and it is used here for referring to the area where the species was found (“Parque Arqueo-Botánico Anikabil” or “Parque Anikabil” for short).
