Pyticeroides pinnacerinis Opitz , new species

Figure 19, 40, 43, 62.

Holotype. Male. ECUADOR: Orellana: 1 km S Onkone Gare Camp , 00 o 39’S 76 o 26’W, 7-X- 1995, 220 m, T.L. Erwin; a second label reads-Fogging leaves in terre firme forest ( USNM). (Specimen point mounted, antenna and gender symbol affixed to paper point; support card; locality label; Natural History label; USNM acronymic label; Holotype label).

Paratypes. None.

Diagnosis (Fig. 62): Male specimens of this species are very similar to male specimens of P. latisentis , from which they differ by characteristics of the aedeagus. In P. pinnacerinis specimens the phallic apex is smaller and the phallobasic rod is divided posteriorly (compare Figure 16, 19).

Description. Size: Length 6.0 mm; width 2.0 mm. Integument: Cranium bicolorous, upper frons infuscate, gena infuscated, vertex flavotestaceous, postocular streaks well expressed; pronotum yellow at upper sides, infuscated at lower sides, piceous discal vitta broad, thoracic venter and abdomen brown; elytra castaneous, except with yellow middiscal fascia that connects to yellow humeral angle by broad yellow epipleural streak; legs predominantly castaneous, femora flavotestaceous in basal half, dark brown in remainder. Head: As wide as pronotum (63:63); ratio of eye width to width of vertex (25:15); antennal funicular antennomeres particularly explanate (Fig.19). Thorax: Pronotum transverse-quadrate (65:50); side margins slightly convex; elytral punctations arranged into 11 rows, 11 th row indistinct near sutural margin, punctations spheroid, those near sutural margin may be misaligned, subseriate, interstitial spaces arenose; elytra about 5.6 x longer than length of pronotum; elytral length to width ratio 4:2; anterior margin of protibia with 9 spines, 8 th and 9 th very small. Abdomen: Male pygidium not emarginate; aedeagus ( Fig. 43 ) short lanceolate; phallic struts broadened at extremities. Mesodermal Male Reproductive Organs ( Fig. 40 ): Two pairs of uniramous accessory glands, medial pair shorter than lateral pair.

Variation. Size: Length 5.6-6.0 mm; width 1.6-2.0 mm. Other than size, the two specimens examined are quite homogeneous.

Natural History. The Holotype was collected by fogging tree branches during October.

Distribution. Specimens are known only from northeastern Ecuador.

Etymology. The specific epithet pinnacerinis is a Latin compound name that stems from the noun pinna (= wing) and the adjective cerinus (= yellowish). I refer to the broad yellow fascia on the elytral disc.

Taxonomic Notes. The most closely related known species of P. pinnacerinis , P. latisentis and P. parvoporis , are also made available in this contribution, therefore no modified key is presented in this section.
