Pujoliclerus corumba Opitz , new species ( Figs. 25 , 53 , 79 , 119 , 126)

Holotype. ♂. Corumba , Matt Grosso ( Brazil) ( DEIG).

Paratypes. Three specimens from the same locality as the holotype ( DEIG) .

Diagnosis. This species is distinguishable from the superficially similar P. flavolimbatus by the brown coloration of the elytral apex.

Description. Size: Length 6.0 mm; width 2.0 mm. Form: As in Fig. 119 . Integument: Frons dark brown, epicranium light yellowbrown, pronotum tricolored, arch yellow, anterior half of pronotum proper red-brown, posterior half dark brown; elytra mostly brown, epipleural fold slightly yellow; femora yellow, protibiae and mesotibiae brown, metatibiae yellow; pterothorax and abdomen brown. Head: Eyes wider than frons (13:10); funicular antennomeres moderately expanded, 6 th antennomere not large ( Fig. 25 ). Thorax: Pronotum transverse (42:39), lateral tubercle not very prominent ( Fig. 53 ); epipleural fold gradually narrowed to elytral apex, asetiferous punctures not prominent to elytral apex. Abdomen: Tegminal lobes and phallic apex as in Fig. 79 .

Natural History. No information is available.

Distribution. Known only from Brazil ( Fig. 126).

Etymology. The specific epithet, corumba , constitutes a noun in apposition and refers to the type locality.

Pujoliclerus flavolimbatus ( Spinola, 1844) ( Figs. 47 , 54 , 80 , 97 , 123 )

Pelonium flavolimbatum Spinola, 1844: 354 . Holotype, ♂ (MIZT). Type locality: Brazil. Schenkling 1910: 128 ( Galeruclerus ); Corporaal 1950: 280 ( Cregya ); Ekis 1975: 53.

Pelonium flavomarginatum Chevrolat, 1874: 327 . New synonymy. Chevrolat, 1876: 7; Schenkling 1906: 315 ( Pelonium ); Corporaal 1950: 280 ( Cregya ). The characteristics on which this nominal species is based fall within the range of variation of P. flavolimbatus . The primary types of both nominal species were examined.

Diagnosis. The brown coloration of the

10 th antennomere will distinguish specimens of this species from superficially similar specimens of P. ovatus .

Description. Size: Length 4.5 mm; width 1.8 mm. Form: As in Fig. 97 . Integument: Head mostly black, clypeus and venter yellow, antenna brown; pronotum black on disc and lower sides, remainder yellow; elytral disc brown, epipleural margin yellow; legs mostly yellow, profemora and tibiae infuscated; pterothorax, and abdomen black. Head: Eyes as wide as frons (14:14); funicular antennomeres slightly expanded, 6 th antennomere triangular ( Fig. 47 ). Thorax: Pronotum transverse (41:35), lateral tubercle very prominent ( Fig. 54 ); asetiferous punctures end at about distal elytral 4/5, epipleural fold gradually diminishes to elytral apex. Abdomen: Tegminal lobes and phallic apex as in Fig. 80 .

Variation. Size: Length 4.0 –5.0 mm; width 1.3-1.8 mm. The pronotum may be mostly black or mostly yellow. The epipleural margin may be pale or brown. The elytra may be mostly yellow or entirely brown.

Natural History. Specimens were collected during October, November, and December, at altitudes ranging from 300 to 500 m.

Distribution. Known from Brazil and Argentina ( Fig. 123 ). In addition to the type specimen, I examined specimens from: BRAZIL: Santa Catarina: Nova Teutonia, XI-1974, F. Plaumann; idem, XII-1938. ARGENTINA: Misiones: Santa Maria, X-1946, M. J. Viana. Specimens are deposited in MLPA, NHRS, and WOPC.

Notes. The above description is based on a homotype housed in WOPC.
