Opisthypselus Reuter, 1909: 5 . Type species: Opisthypsellus punctaticollis Reuter, 1909 .

Diagnostic characters. Elongate, ant-mimetic species. Shiny dorsally, with sparse long hairs. Head long; portion before eyes curved downward; eyes rounded, projecting, well separated from anterior margin of pronotum; antennae slender and long; segment II slightly widened toward its apex. Pronotum subtriangular, smooth; pronotal collar wide; anterior margin narrower than base of head; lateral and basal margins straight; posterior lobe with some strong punctures; both lobes separated by a row of punctures; scutellum slightly elevated. Hemelytra with lateral sides sinuated and with strong punctures as in pronotum; cuneal fracture long, reaching corial-claval suture. Legs slender and very long; unarmed; pseudo-pads at apex on fore and mid tibiae consisting of short membranous prominence bearing long hairs. Abdomen very constricted basally. Uradenia typical. Dorsal half of metapleura smooth; ostiolar peritreme ( Fig. 23 View Figs ), placed basally in metapleura, short, wide, straight, inclined backward and rounded apically; median sulcus reaching only the basal quarter of peritreme.

Studied material. Opisthypselus punctaticollis Reuter, 1908 : BRAZIL: Río de Janeiro, Tijuca, 10/ VI /1963, 1 J (slide mounted), San Martín lgt. ( MACN). NICARAGUA: Zelaya: C Saslaya, IV- 1996, 4 ♀♀, Maës – Hernandez lgt. ( MACN).

Remarks. This is the most modified genus of Scolopini . The ostiolar peritreme is probably the most characteristic of all Anthocoridae . CARPINTERO (2002) transferred this genus to Lasiochilinae based on the shape of ostiolar peritreme, straight with dorsal half of metapleura smooth. However, here we restore its position according to CARAYON (1972). The male genitalia have never been described; unfortunately, the single male we studied had lost the pygophore, and we could not study genital structures but we could see the typical uradenia of the Scolopini .
