Description
: Head: Dark brown, fine punctures with scattered larger round punctures, covered with decumbent pale hair; frons convex becoming flat toward anterior margin with well-developed apical carina; antennae just reaching the hind angles in males, not reaching the hind angles by about one antennomere in females; antennomere 2 subconical, slightly shorter than antennomere 3; antennomeres 3–10 feebly dilated at apex, longer than wide; antennomere 11 subellipsoidal, narrowed at apex.
Pronotum: As long as wide, convex, widest at middle, dark brown to black, densely and finely round punctures with scattered larger round punctures, lateral margins arcuate; hind angles sharply truncate, carinate dorsally.
Scutellum: Dark brown medially, more blackish along suture, slightly wider than long, heart- shaped, emarginate at base.
Elytra: Yellowish-brown, medially shaded with black (
Fig. 6
), covered with dense erect yellow setae, striae densely and finely punctate with scattered large rounded punctures, interstriae deeply punctate.
Male genitalia
: Parameres without a distinctly produced subapical rounded lobe, apicolateral expansion reduced, teardrop-like, two setae below expansion, distal setae long; median lobe simple, subparallel margins beyond middle apically narrowly rounded (
Fig. 7
).
Female genitalia
: Proximal sclerite of the bursa copulatrix with 9–11 large marginal teeth, terminal teeth largest, and 11–13 smaller internal discal teeth including one just below large marginal terminal tooth (
Fig. 8
).
Etymology.
The patronym honors Latifa A. Almutlaq.
Diagnosis.
Dicronychus latifae
is most similar to
D. brancuccii
, but can be distinguished in the female by fewer teeth of the proximal sclerite of the bursa copulatrix (
Fig. 8
). The parameres of the male genitalia lack the distinctly produced subapical rounded lateral lobe with the triangular expansions (
Fig. 7
), as present in
D. brancuccii
(
Fig. 4
). Additionally the apex of the median lobe is more narrowly rounded than either
D. brancuccii
(
Fig. 4
) or
D. bushrae
n. sp.
(
Fig. 10
).
