Priocera marginicollis ( CHEVROLAT, 1843) (Figs 59, 92, 147)

Clerus marginicollis CHEVROLAT, 1843: 31 .

LECTOTYPE: Gender not known. Type locality: Brasilia, D. A. Pompon ( Brazil). Here designated. ( MNHN). CORPORAAL 1950 : 100. CHEVROLAT did not select a holotype, therefore, I invoke Recommendation 73F of the ICZN (1999) and designate a lectotype for this nominal species.

A d d i t i o n a l m a t e r i a l e x a m i n e d ( Fig.92 ): Inadditiontothelectotype, I examined 10 specimens from: Brazil: Estado do Rio de Janeiro, Parque Nacional Itatáial , 4-IV-1964, 1,200 m, C. E. & E. S. Ross ; Nova Friburgo ,?-IV-V-1884, P. Germain ; Estado do São Paulo, Caraça ,?-?-1884, P. Germain ; Estado do Santa Catarina, Nova Teutonia ,?- I-1973, 300- 500 m, Fritz Plaumann ; idem,?- II-1974, F. Plumann ; Specimens are deposited in: CASC, FMNH, WFBM, and WOPC .

D i a g n o s i s: Forebody black, except pronotal posterior angles and pronotal collar testaceous; antennae, pterothorax, and legs testaceaous; elytral bicolored, basal 1/2 testaceous, testaceous region extends posteriorly along sutural margin to conjoin short oblique, testaceous fascia, apical half mostly black, apical region testaceous; abdomen black.

R e d e s c r i p t i o n: Size: Length 12.0 mm; width 4.0 mm. Form: As in Fig. 147 . Head: Cranium conspicuously wrinkled; frons wider than length of antennal pedicel; EW/FW 50/60. Thorax: Pronotum faintly wrinkled at sides, finely punctate in remainder, disc with 2 tumescenses (PW/PL 150/200); elytral disc sculptured with substriate, asetiferous punctures that extend just behind elytral basal 1/2, elytral apex narrowly rounded (EL/EW 530/100); metathoracic femur gradually increasing in diameter to femoral apex. Abdomen: Aedeagus as in Fig. 59.

V a r i a t i o n: Size: Length 10.0-14.0 mm; width 3.0-4.0 mm. Other than body size, the available specimens are quite homogeneous.

N a t u r a l h i s t o r y: Specimens were collected during January, February, April, and May.

N o t e s: The lectotype was examined, but the description is based on a homotype specimen.
