Type material examined. Holotype ♂, COSTA RICA, Alajuela, Heredia, X.1958, J.O. Fernandes leg. ( USNM) . Paratypes: PANAMA, [Colón], Coco Solo , ♂ <illustrated specimen>, ♀, Canal zone/ Hospital , 17.XII.1972, D.D. Engleman leg. ( UFRG) ; ♂ ( MCNZ) ; 1♂ 1♀ ( AMNH) .

Other material examined. PANAMA, ♀, [Colón], Coco Solo, Canal zone/ Hospital, Oenopiella sp ?, D. Engleman det. ( USNM) <illustrated specimen>.

Diagnose. Mandibular plates longer than clypeus; mesial margins of mandibular plates parallel ( Fig. 85 ). Proportions of antennomeres: 1 ~ 2> 3> 4 <5 ( Fig. 85 ). Posterior margins of bucculae not reaching base of head. Labium median, attaining the metacoxae ( Figs 14 , 84 ). 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 long, reaching more than half of peritreme. Evaporatorium on mesopleuron reaching less than half of the segment. Gyrification of evaporatorium with low wrinkles. Metathoracic spiracle wide. Hemelytra not surpassing the abdominal apex ( Figs 57 , 83 ). Connexivum exposed, angles not concolour to dorsal color. Spiracles elliptical, spiracle of abdominal sternite 2 not covered by metathorax. Mesial area adjacent to spiracles with callosity ( Figs 14 , 86 , black arrow).

Measurements. See Table 1 .

Male genitalia. Posterolateral angles of pygophore quadrate ( Figs 87–89 ). Genital cup occupying more than half of pygophore length ( Fig. 87 ). Extension of dorsal rim obsolete. Layers of ventral rim not separated by a carina; area between layers excavated ( Fig. 88 ). Inferior layer of ventral rim without process ( Fig. 89 ). Phallus ( Figs 90– 92 ): Dorsal connective shorter, reaching the middle of phallotheca. Processus capitati longer, reaching phallotheca distal margin. Dorsal processes of phallotheca medially narrow, shorter than posterodorsal projection.

Female genitalia. Valvifers 8 convex, posterior margins sinuous. Valvifers 9 swollen, with anterior margins concave and posterior margins straight, sclerotized lateral arms attaining anterior margins of laterotergite 9 ( Fig. 93 ). Proximal ductus receptaculi twisted, short in relation to the length of vesicular area. Distal ductus receptaculi convoluted, shorter than vesicular area.Annular flanges convergent related to each other. Capsula seminalis globose (see Fernandes & Grazia, 1996: 352, fig. 39).

Distribution. Honduras; Nicaragua (Managua); Costa Rica (Heredia); Panama (Canal Zone); Colombia; Venezuela (Zulia) ( Fig. 111 ).
