Diagnosis. Iphiclus guadeloupensis is recognized by its elongate-oval body shape, black body with dark yellow-brown elytra having paler margins (sutural margin not black) ( Fig. 8 , 47 ), and distinct gemellate strial punctures.

Description. Length: 8.0-10.0 mm; width: 5.0- 6.5 mm. Body elongate-oval, dorsally convex (not globose), acuminate posteriorly; cuticular surface weakly microreticulate, shining. Body and appendages black except noted: elytra yellow-brown often with pale edges; abdomen yellow-brown.

Head interocular width = 3.5 x ocular width; ocular striae attaining base of epistome; vertex punctures faint to absent; epistome puncture size = 1.5 x ocular facet diameter, separated by 2 x their diameter, impressed and readily visible. Antenna attaining pronotal base; antennomere II length = width, length = 0.5 x antennomere III; antennomere III length = 3 x width, length = length of antennomeres IV+V combined; antennomeres IV-VIII equal in length; antennomeres IV-VII each with length = 1.5 x width; VIII triangular, part of club, length = width; antennomere IX trapezoidal, nearly parallel-sided ( Fig. 47 ), length = 1.3 x width; antennomere X crescent shape, length = 0.66 x IX length; antennomere XI subcircular, length = 0.75 x IX length. Terminal maxillary palpomere securiform, length = 0.8 x width. Terminal labial palpomere triangular, width = length, expanded medially, width = 0.8 x width of termi- nal maxillary palpomere. Mentum with triangular plate weakly defined, length = 1.2 x width. Genal lobes present, short, blunt.

Pronotum transverse, width = 2 x length, anterior width = 0.75 x posterior width; punctures fine, weak to absent, obscured by microreticulation; sides not depressed, in lateral view margin straight; base lacking large punctures; anterior edge with fine, complete marginal bead; base sinuate, marginal bead lacking. Scutellum triangularly rounded, length = width. Elytra with paired striae, punctures large, puncture size = 2 x ocular facet diameter, separated by 1-2 x their diameter; interval punctures lacking; base lacking marginal bead.

Prosternum length = 3 x intercoxal width; anterior edge with marginal bead, not pinched; prosternum convex, depressed anterior and posterior of coxa, not punctate; sternal lines continuous around coxal cavity; base weakly concave ( Fig. 49 ). Mesosternum truncate, lines divergent anteriorly, continuous around coxal cavity; punctures absent. Metasternum with lines not meeting medially; continuous around mesocoxal cavity; punctures absent. Abdomen with coxal lines not meeting medially; continuous around metacoxal cavity; punctures fine, indistinct; few punctures present at posterior margin of last abdominal ventrite. Male and female lacking small group of setose punctures at center of first abdominal ventrite. Male genitalia ( Fig. 51 ) similar to I. suturalis .
