Ecuador : Orellana : Tiputini Biodiversity Station , 00 o 37’S 76 o 08’W , 21-X- 1998 , 220- 250 m , T. L. Erwin ( USNM , 1) ; idem , 1-VII-1994 , T. L. Erwin ( WOPC , 1) . Diagnosis (Fig. 59): Pyticeroides latisentis is most closely related to P . inexilis Opitz. Specimens of these two species are readily separated by the width of the funicular antennomeres, which are very broad in P . latisentis specimens. They are narrower in P . inexilis specimens (compare Figure 16, 17). Also, in P . inexilis specimens the elytral disc shows a broad yellow fascia that is narrowly connected to the yellow humerus by a yellow epipleural streak. The elytra are uniformly piceous in specimens of P . inexilis . Description. Size : Length 4.5 mm ; width 1.8 mm . Integument : Cranium mostly flavotestaceous, frons piceous, piceous postocular streaks prominent; pronotal sides yellow, discal piceous line broad; elytra bicolorous, with a broad yellow fascia that connects via yellow narrow band to yellow humerus, remainder of elytral disc piceous; legs light brown, femora increasingly more yellow at base from profemur to metafemur. Head : Slightly wider than width of pronotum (47:44), ratio of eye width to width of vertex (20:9); eyes not very bulged; antenna (Fig. 16), funicular antennomeres very expanded, antennomere 7 distinctly rectangulate. Thorax : Pronotum subquadrate (44:40); side margins subparallel; elytral punctations seriate, interstitial spaces smooth, shiny; elytral epipleural margin minutely serrulated in posterior half; elytra about 5 x longer than pronotum; elytra length to width ration about 6:2; anterior margin of protibia with 5 spines. Abdomen : Male pygidium not emarginate; aedeagus ( Fig. 35 ) lanceolate, aedeagal phallobasic apodeme and phallic struts not broadened at extremities. Mesodermal Male Reproductive Organs : Two pairs of uniramous accessory glands, medial pair considerably narrower than lateral pair ( Fig. 39 ). Variation. Size : Length 4.5-5.0 mm; width 1.6-1.8 mm . The pronotum of the paratype is nearly completely piceous; only the anterior angles are slightly flavotestaceous. Natural History. Specimens have been collected in July and October at altitudes ranging from 220- 250 m . Distribution. This species is known only from northeastern Ecuador . Etymology. The genus name Pyticeroides Kuwert is masculine. The specific epithet latisentis is a Latin compound name formed from the adjective latus (= broad) and the verb sentio (= feel). I refer to the broadened funicular antennomeres in these beetles. Taxonomic Notes. Of the known species of Pyticeroides , P . latisentis specimens are most closely allied to P . inexilis . The key to species as presented in Opitz (2007: 101) should be modified as follows: 2(1). First antennomere of antennal club rectangular ........................................................................ 3 – First antennomere of antennal club somewhat triangular ......................................................... 4 3(2). Elytral disc with broad medial yellow fascia; funicular antennomeres very broad (Fig.16) ( Ecuador : Orellana ) ....................................................................... Pyticeroides latisentis Opitz , n.sp. – Elytral disc without broad yellow fascia; funicular antennomeres not very broad (Fig. 17) (Prazil: Paran, Sao Paulo ) ........................................................................ Pyticeroides inexilis Opitz
