Type material examined. Holotype ♀ , TRINIDAD and TOBAGO , S[aint] Augustine , IV.1929 , Darlington leg. ( AMNH ) <illustrated specimen>. Diagnosis. Mandibular plates equal than clypeus. Proportions of antennomeres: 1> 2 <3> 4 <5 (Fig. 96). Posterior margins of bucculae reaching base of head. Labium median, attaining the metacoxae (Fig. 94). Proportions of labiomeres: 1 <2> 3> 4. Each peritreme of ESES reaching about 1/3 of the distance to lateral margin of evaporatorium. Median furrow of the peritreme short, reaching less than half of peritreme. Evaporatorium on mesopleuron reaching more than half of the segment. Metathoracic spiracle wide. Hemelytra not surpassing the abdominal apex ( Fig. 58 ). Connexivum exposed, anterior angles not concolour to dorsal color. Spiracles circular, spiracle of abdominal sternite 2 not covered by metathorax. Mesial area adjacent to spiracles with callosity. Measurements. See Table 1 . Male genitalia. Posterolateral angles of pygophore quadrate. Genital cup occupying more than half of pygophore length. Extension of dorsal rim obsolete. Layers of ventral rim not separated by a carina; area between layers excavated. Inferior layer of ventral rim without process. Phallus : Dorsal connectives shorter, reaching the middle of phallotheca . Processus capitati longer, surpassing phallotheca distal margin. Dorsal processes of phallotheca wider at the base, shorter than posterodorsal projections (see Fernandes & Grazia, 1996: 348–350 , figs 21, 26, 31). Distribution.
