Paratype: 1 specimen. French Guiana: Subdivision Maripasoula, Massif du Mitaraka, 21°4'N- 54°27'W, 25-II-26-III-2015, La Planète Revisitée- MNHN.PNI Guyane, 2015 (APA-973-1) ( WOPC).

D i a g n o s i s: The genus Plocamocera SPINOLA was revised in 2004 ( OPITZ, 2004). This work included a key to species. Plocamocera catalexis specimens key out to P. onorei OPITZ from which Plocamocera catalexis specimens differ by showing a disconnection of components of the elytral inverted T marking near the humeral angle and by the narrower capitular antennomeres.

D e s c r i p t i o n: Size: Length 4.1 mm; width 1.5 mm. Form: As in Fig. 303 . Color: Cranium and prothorax piceous; pronotal periphery castaneous; pterothorax piceous; elytra variegated, flavotestaceous humeral inverted T macula disconnected, testaceous postmedial macula proximal to epipleural margin, subapical testaceous fascia angular and extended from epipleural to sutural margins, apex testaceous; legs mostly yellow, femora and tibiae infuscated; abdomen brown. Head: Antenna ( Fig. 48 ) capitate, with long filamentous sensilla trichodea, scape and pedicel particularly prominent, funicular antennomeres minute, capitular antennomeres narrow-oblong; eyes large, finely facetted, ocular notch large, eye much wider than frons (EW/FW 27/16). Thorax: Pronotum ( Fig. 106 ) transverse (PW/PL 65/42), disc finely punctate, lateral tubercle well developed, disc concave paralaterally near pronotal collar; discal and lateral trichobothria prominent; elytral asetiferous punctures small, profusely distributed (EL/EW 200/50); anterior margin of protibia with 2 spines. Abdomen: Pygidium transverse/scutiform.

N a t u r a l H i s t o r y: The available specimen was collected during a period between February 25 and March 26.

D i s t r i b u t i o n: This species is known from French Guiana.

E t y m o l o g y: The trivial name, catalexis, is a Greek name with the meaning of "end"; with reference to the pale elytral apex.
