Opitz, Weston, 2010, New taxa of Epiphloeinae Kuwert (Cleridae) and Chaetosomatidae Crowson (Coleoptera: Cleroidea), Insecta Mundi 2010 (123), pp. 1-28 : 17-18

Plocamocera clinata Opitz , new species

Figure 8 , 57 .

Holotype. Female. BOLIVIA: Santa Cruz, 3.7 km SSE Buena Vista, Hotel Flora & Fauna , 405 m., 5-15- XI-2001, 17 o 29.949’S; 63 o 33.152’W, M.C.Thomas & K. Dozier, tropical transition forest ( MNKM). (Specimen point mounted, antenna and gender label affixed to paper point; support card; locality label; FSCA acronymic label; Holotype label.)

Paratypes. Five specimens. Bolivia: Santa Cruz: 3.7 km SSE Buena Vista, Hotel Flora & Fauna , 17 o 29.949’S 63 o 33.152’W, 5-15-XI-2001, tropical transition forest, 405 m, M.C. Thomas & K. Dozier, ( FSCA, 2; WOPC, 3) .

Diagnosis ( Fig. 57 ): Specimens of this species resemble superficially those of P. quadrula Opitz , from which they are easily distinguished by the shape of their antennal club (compare Figure 7, 8 ).

Description. Size: Length 6.0 mm; width 2.3 mm. Integument: Cranium dark castaneous; pronotum castaneous, disc infuscated; remainder of thorax castaneous except profemur and mesofemur dark brown, metafemur dark brown in distal half and yellow in proximal half, tibiae and tarsi brown; elytral color variegated, predominantly dark-castaneous, flavotestaceous triagonal posthumeral macula well developed. Head: Antenna as in figure 8. Thorax: Pronotal anterior margin notably projected at middle; elytral epipleural margin with conspicuous trichobothria; protibial anterior margin with 3 spines. Abdomen: Female pygidium narrow scutiform.

Variation. Size: Length 4.8-6.0 mm; width 1.5-2.3 mm. Other than size, the beetles before me are quite homogeneous.

Natural History. The available specimens were collected in November from a tropical transition forest, from 152 to 405 m.

Distribution. Known only from the type locality.

Etymology. The genus name Plocamocera Spinola is feminine. The trivial name clinata is a Latin adjective that stems from clino (= slope). I refer to the sloping outline of the posterior margin of the last antennomere.

Taxonomic Notes. The key to species of Plocamocera Spinola ( Opitz, 2004: 28) should be modified as follows to accommodate this species:

14(13). Tripartite elytral post humeral flavotestaceous macula clearly defined ................................... 15 – Tripartite elytral post humeral flavotestaceous macula not clearly defined ............................ 16

15(14). Ninth antennomere slender ( Fig. 7 ) ( Brazil: Mato Grosso) ...... Plocamocera quadrula Opitz – Ninth antennomere robust ( Fig. 8 ) ( Bolivia; Santa Cruz) .............................................................
