Diagnosis.
Xenopygus davidi
can be easily placed in the
punctatus
species group based on the punctation of the pronotum. Among taxa in the
punctatus
group,
X. davidi
is distinguished by the bright orange coloration of the elytra and the shape of paramere which is (in dorsal view) wide anteriorly and with peg setae only on the lateral margins of paramere (
Fig. 6
).
Xenopygus pycnos
has also light brown to orange elytra but the two species can be easily separated based on the punctation patterns of the head and thorax (punctures confluent in
X. pycnos
).
Description.
Body length
10.1–11.4 mm
. Coloration of head, neck and pronotum brown with shining metallic green overtones. Mouthparts reddish-brown; antennae brown. Ventral surface of head brown; ventral surface of thorax and legs reddish brown. Elytra bright orange; mesoscutellum orange to brown. Abdominal segments III–V brown medially with reddish brown laterally and on paratergites. Segment VI mostly brown with paratergites reddish-brown. Abdominal sternite VII brown except posterior 1/5 reddish-brown; sternite VIII dark orange.
Head transverse, width:length ratio = 1.18; eyes large, prominent, head:eye length ratio = 1.55; head with deep medium sized punctures except medially, distance between punctures equal to 0.5–1 times width of puncture; epicranium with sparse microsculpture. Antennae with microtrichiae starting on antennomere 4; antennomeres 1–3 longer than wide; antennomere 4 subquadrate; antennomeres 5–10 transverse, progressively becoming wider. Labial palpomere 3 truncate, slightly dilated. Pronotum longer than wide, pronotum width:length ratio = 0.95; pronotum with multiple rows of medium sized punctures; pronotum midline without punctures. Pronotum subequal in length to elytra; elytra covered with confluent medium sized punctures. Abdominal tergum V without an archlike carina; abdominal terga III–VI with patches of yellow setae on anterolateral corners.
Secondary sexual structures. Males with shallow emargination on posterior margin of sternite VII; porose structure absent on sternite VII; sternite VIII with shallow V-shaped emargination on posterior margin. Females with no apparent secondary sexual structures.
Aedeagus as in
Figs. 4–6
; in dorsal view paramere wide, converging to rounded tip; paramere slightly shorter and narrower than median lobe; in lateral view paramere slightly concave, with wider region medially; paramere with peg setae away from tip. Median lobe in dorsal view wide, parallel-sided, converging to pointed apex, with two small teeth apically; in lateral view becoming narrower near apex.
Etymology.
The epithet is in honor of Dr. David Brzoska, who collected many of the specimens in the
type
series.
