sERICELLA GROUP Plocamocera argentea , new species Figures 48 , 68, 69, 83, 97, 118; map 5

HOLOTYPE: Male. Bolivia: Santa Cruz: Prov. del Sara , 450 m, Dec. 1909, J. Steinbach ( CMNH). (Specimen pin mounted, locality label, beige, machine printed; Carnegie Museum accession label, beige, Acc. 4552, machine printed; repository label, white machine printed; sex of specimen indicated on holotype label; plastic vial with aedeagus.)

PARATYPES: Fifteen specimens from the same locality as the holotype ( CMNH, 8; WOPC, 7) .

DIAGNOSIS: Specimens from Bolivia belong to this species if their integument is brunneus and the elytra are vested with three silvery setal fascia. These characteristics distinguish the members of this species from congeners.

DESCRIPTION: Size: Length 5.0–6.0 mm; width 1.5–2.0 mm. Integument: Cranium, thorax, and abdomen castaneous; femur flavotestaceous; elytra (fig. 68) brunneus, with three silvery setal fascia that are bordered by piceous markings. Head: Antenna as in figure 48. Thorax: Pronotal anterior margin moderately projected at middle; elytra without trigonal post­humeral macula (fig. 68); elytral epipleural margin with five conspicuous trichobothria (fig. 69); anterior margin of protibia (fig. 83) with six spines. Abdomen: Male pygidium broad­scutiform (fig. 97), female pygidium broad­scutiform; aedeagus (fig. 118) conspicuously elongated.

VARIATION: The available specimens are quite homogeneous.

NATURAL HISTORY: Specimens were collected from the type locality during December, at 450 m.

DISTRIBUTION (map 5): Known only from the type locality.

ETYMOLOGY: From the Latin adjective argenteus (silvery). I refer to the silvery setal fasciae on the elytra.

Plocamocera auratilis , new species Figures 49 , 66, 67, 74, 81, 166, 172; map 5

HOLOTYPE: Male. Panama: Panama: Pan American Hwy. 30 km E of Canita , 15–29 June 1992, Jean & Keve Ricardo ( AMNH).

Wappes ( JEWC, 1) .

DIAGNOSIS: The specimens of this species are easily distinguishable by the gold­yellow coloration of the elytral setae which are unique within the sericella species group.

DESCRIPTION: Size: Length 4.5–5.0 mm; width 1.5–2.0 mm. Integument: Predominantly light­ castaneous, pronotal disc infuscated; mesoscutellum piceous; elytral disc infuscated at sides along epipleural margin and at apex, profusely vested with gold­yellow setae which are particularly prominent along sutural margin, with four patches of silvery setae contiguous with sutural margin (fig. 66); legs predominantly flavotestaceous, distal half of femora and proximal half of tibiae infuscated, tarsus flavotestaceous. Head: Antenna as in figures 49, 166. Thorax: Pronotal anterior margin particularly projected at middle, discal swellings prominent; elytra notable expanded along epipleural margin at basal third (fig. 74), elytral epipleural margin with four conspicuous trichobothria (fig. 67); anterior margin of protibia (fig. 81) with two spines. Abdomen: Male pygidium broad­scutiform, truncate, female pygidium trigonalscutiform; aedeagus as in figure 172.

VARIATION: The dark regions on the integument are more pronounced in the specimen from Costa Rica and in the one from El Llano, Panama.

NATURAL HISTORY: The available specimens were collected during November from Costa Rica, during May and June from Panama, and during February from Bolivia.

DISTRIBUTION (map 5): Known from Costa Rica and Panama.

ETYMOLOGY: From the Latin adjective auratilis (gold colored). I refer to the golden sheen characteristic of the elytral surface so apparent in these beetles.

Plocamocera sericella Spinola Figures 47 , 61, 82, 96, 108, 117, 133, 135, 156, 211; map 4

Plocamocera sericella Spinola, 1844b: 19 . Neotype: Male. Here selected. Panama: Canal Zone: Madden Forest, mile 2.5, I– VII–1974, C. & L. O’Brien & Marshall (AMNH). The original type locality was ‘‘Carthagene’’ (Columbia). I did not find Spinola’s type specimen in the Spinola Collection (Ekis, now Opitz, 1975: 63) nor in the collection of the MNHN. However, Spinola’s description, and illustration ( Spinola 1844b: 9, plate 38, fig. 4), provides a clear understanding about the identification of this spe­ cies. (Neotype specimen point mounted, sex label affixed to paper point, white, point, hand printed; support card, white; locality label, white, machine printed; AMNH repository label, white, machine printed; neotype label, red, machine printed.)

Epiphloeus byssinus Erichson, 1847: 86 . Lectotype. Female. Here selected. Peru (MNHB). (Specimen point mounted; support card, white; locality label, blue­green, cursive; lectotype label, red, cursive; specimen label, white (58855); identification label, white, machine printed.) NEW SYNONYMY. There are no appreciable differences between the type of this junior synonym and the type specimen of the senior synonym. Corporaal, 1950: 253.

Plocamocera latefasciata Pic, 1942: 3 . Holotype. Female. Examined. French Guiana: Cayenne: Nouveau Chantier, Collection Le Moult, Mars (MNHN). (Specimen card mounted; sex label affixed to mountcard, beige, outlined in black, machine printed; collection date label, beige, outlined in black, machine printed; identification label mounted on beige support card, beige, cursive; type label, beige, cursive; Museum Paris specimen number label, light blue, outlined in black, machine and hand printed; MNHN repository label, white, machine print­ ed; holotype label, red, machine printed.) NEW SYNONYMY. There are no appreciable differences between the type specimen of this junior synonym and the type specimen of the senior synonym. Corporaal, 1950: 255.

DIAGNOSIS: The pronotal disc is piceous and the elytra do not have conspicuous macula, but they do have three irregularly shaped setal fascia that range from white to grey. The elytral humeral macula are more pronounced in South American specimens. These clerids are readily distinguishable from superficially similar specimens of P. sericellopsis , by the presence of four spines on the protibia. In P. cericellopsis the protibia show three spines.

DESCRIPTION: Size: Length 3.6–5.1 mm; width 1.2–2.0 mm. Integument: Cranium piceous; pronotum castaneous, disc with large piceous macula; elytra variegated, predominantly light castaneous, disc with two piceous macula; elytra variegated, predominantly light castaneous, disc with two piceous macula posterior to transverse bands of white se­ tae, gold­yellow setae prominently distribut­ ed along sutural margin, apex piceous, legs flavotestaceous. Head: Antenna as in figure 47. Thorax: Pronotum prominently and acutely projected at middle, discal swellings very prominent; elytral epipleural margin with four conspicuous trichobothria (fig. 61); protibia with four spines (fig. 82). Abdomen: Male (fig. 96) and female pygidia broad­scutiform, with two discal and six marginal stout setae; aedeagus as in figure 117. Internal Reproductive Organs: Organs of the male and female, and of the alimentary canal, are as described in Opitz (1997: 71).

VARIATION: The dark areas of the elytra become more pronounced in specimens from South America, especially those from French Guiana and Brazil. In some of these beetles the legs are infuscated and the elytra are marked with piceous maculae.

NATURAL HISTORY: These beetles were collected throughout the year from altitudes that range from 150 to 1300 m. Specimens were captured on dry branches of Magnifer indica , others were captured at night by light, on Ficus . Some specimens were taken in a Malaise trap braced over newly felled tree trunks.
