Epimetopus apocinus Perkins, 1979: 323. New collection records: Costa Rica: Guanacaste, 18.7 kmNW Bagaces, Hwy1, Rio Carana, elev. 91 m, 10° 39' N, 85° 22' W, 4 vi 1973, Erwin& Hevel(5 USNM); Limon, Reventazon, Hamburg Farm, at light, 10° 15' N, 83° 28' W, 27 v 1935, F. Nevermann(2 FMNH); Puntarenas, Corcovado National Park, Sirena Stn., lower Ollas Trail, ex. UV light, elev. 5 m, 8° 24' N, 83° 35' W, 25 v 2000, Z. H. Falin(CR1ABF00) (5 SEMC); Mexico: Tabasco, Rio Puyacatengo, E. Teapa, 17° 33' N, 92° 57' W, 28–29 vii 1966, Flint& Ortiz(1 USNM).
Differential diagnosis.The habitus of E. apocinus( Fig. 44) is quite similar to other members of the Costatusgroup; reliable determinations will require examination of the male genitalia. The aedeagus has arching parameres somewhat similar to those of E. mucronatus, but otherwise the aedeagi of the two species are quite dissimilar ( Figs. 48, 56). The aedeagus of E. apocinusis larger and wider, the median lobe is less acutely pointed apically, and the parameres are arched differently and, in lateral view, are sinuate. Externally, E. apocinushas elongate granules linking the elytral punctures, whereas in E. mucronatusthe granules do not link the punctures. E. ballatoris( Fig. 30) also has arcuate parameres that arch over the median lobe; however, the extent of the arching is much more than in E. apocinus. The median lobe of E. ballatoris, which tapers distinctively in the distal one-half also clearly differs from that of E. apocinus. The pronotal lateral lobes are slightly less angulate in E. apocinusthan in E. ballatoris( Figs. 26, 44).
Distribution.Currently known from Costa Ricaand Mexico( Fig. 139).
