Quammenis spectabilis Erwin , new species

( Figs. 1a, 1b )

Type Series. Holotype female, COSTA RICA: Heredia Province, Estacíon Magsasay, Parque Nacional Braulio Carrillo , 200 m, LN 64600,531100, October, (A. Fernandez)( INBio: CRI 000–647080).

Derivation of Name. The species name, spectabilis , is an adjective describing the elegance of this metallic green mountain beetle.

Diagnosis. ( Fig. 1a ) As described for genus.

Description. As described for genus. Size moderately small: 6.44 to 7.32 mm in length, 2.56 to 2.76 in width. Aedeagus ( Fig. 1b ) without armature on the endophallus; right paramere small, narrow.

Specimens Examined. Paratypes: COSTA RICA: 1 male, Cartago Province, Pacayas , 1600 m, 098559N, 0838489W, (C. Werckele)( AMNH)

ADP44192; 1 female, San Jose Province, Estacíon Zurqui , 500 meters before the tunnel, 1600 m, LN226800,535200, April, (G. Maass)( USNM) ADP100513 .

Notes. Remarkably, this species has remained unnoticed. I suspect it lives among mossy boulders at the steep sunny edges of mountain torrents, a slippery and perhaps dangerous place to collect.

Lebiini : Lebiina Lebia (Chelonodema) inbio Erwin , new species ( Figs. 2a, 2b )

Type Series. Holotype male, COSTA RICA: Guanacaste Province, Estacíon Pitilla , 9 km S Santa Cecilia, 700 m, LN329950,380450 #4355 (C. Moraga)( INBio: CRI 002­134601 ) . Paratypes, 5 males, 13 females from the type locality (11­ INBio, 2­ CAS, 2­ UASM, 3­ USNM) , 1 male, Estacíon Maritza, west slope of Volcan Orosi , 600 m, LN326900,373000 (K. Taylor)( INBio: CRI 000­394820) ; 1 male, Alajuela Province, Estacíon San Ramon , 620 m, LN318100,381900 #2817 (F. Quesada)( INBio: CRI 001­776999 ) , 1 male, Sect. San Ramon de Dos Rios , 1.5 km N Hde. Nueva Zelandia, 620 m, LN 318100,381900 #7332 (F. Quesada) ( USNM) , 1 male, Finca San Gabriel , 2 km SW Dos Rios, 600 m, LN318800,383500 (GNP Biodiv. Survey)( INBio: CRI 001­024138 ) .

Derivation of Name. The specific epithet, inbio , an acronym for the Costa Rican institution in which the type series was encountered is used as a noun in apposition.

Diagnosis. This is the only species of Lebia (Chelonodema) with two longitudinal and bordered spots on the elytron ( Fig. 2a ) which cover 2/3 of the elytral surface.

Description. Testaceous; each elytron with 3 ‘‘spots,’’ the scutellar one black, the discal ones beige with back borders; palpi, antennomeres 3–11, femoral apex, tibiae and tarsomeres black. Pronotum broadly explanate; disc finely rugose. Size moderately large: 9.8 to 11.84 mm in length, 5.38 to 5.86 mm in width. Aedeagus ( Fig. 2b ).

Specimens Examined. The type series of 23 specimens is listed above. Notes. This species does not trace satisfactorily in Reichardt’s key (1972)

due to the unique elytral color pattern; the key will need to be significantly reordered rather than simply adding a step.
