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 ........................................................................

– First antennomere of antennal club somewhat triangular .........................................................

3(2). Elytral disc with broad medial yellow fascia; funicular antennomeres very broad (Fig.16) (

Orellana
) .......................................................................
