Diagnosis.— This species may be confused with T. ebanoverde , with which it shares an island; but if differs as follows: narrowest point of furculae about one third its entire length; epiproct lateral ridges bilobed, and off­center mounds elongate and narrow ( Fig. 6 D) (off­center mounds wide in T. ebanoverde ); profile of endophallic plate as in 11D.

Description.— Male. Head: Eyes reddish brown. Antennae filiform, with 21 ­ 22 segments, the first four reddish the remaining brown. Pronotum: Dorsally marked by dark annular area, which is centrally lighter and surrounded by fine cream yellowish bands that are themselves surrounded by black. Wide green band on most of lateral area, delimited below by cream yellowish band and small streak of brown at center of lower pronotal margin. Metanotum markedly pitted. Wings: Tegmina short, rounded, extended to 4th abdominal segment, colored pink reddish anteriorly and black in their posterior and outer margins. Tegmina dorsally overlapping in one of four adult males. Abdomen: Abdominal end bulging, less bright green than head, thorax and epimera, also with hues of brown. Furculae cylindrical and joined below, strongly sclerotized and black, exaggeratedly long.

Etymology.— Name in aposition, in reference to its type locality.

Type material.— Holotype: Male. DOMINICAN REPUBLIC, Santiago prov., Monte Diego de Ocampo, summit, 1300 m, 26.viii.1995, D. E. Perez, B.Hierro, S. Navarro ( ANSP). Allotype: Same data as holotype ( ANSP). Paratypes: Two adult and 1 juvenile males, 1 adult and 1 juvenile female, same data as holotype ( ANSP). One adult male and 1 adult female deposited in DEPG collection.
