Diagnosis. Notaepytus flavitarsis is readily recognized by the mostly orange pronotum with two apical and four basal spots ( Fig. 83 View Figure 81-84 , 89 View Figure 89-104 , 121 View Figure 121-123 ).

Description. Length: 6.1-8.5 mm; width: 2.8-3.5 mm. Body elongate, parallel-sided, somewhat flattened; surface microreticulate. Color black except as noted: pronotum orangish with 2 widely separated black spots on apical margin and 4 basal black spots connected along the basal margin ( Fig. 83 View Figure 81-84 , 89 View Figure 89-104 , 121 View Figure 121-123 ); elytra with jagged orangish band at basal third and apical quarter; pronotal hypomeron and posterior 3/ 4 elytral epipleural fold orangish; tarsi, last 2 abdominal ventrites, and palpi reddish-brown; antennomere XI pale.

Head interocular width = 2.0-2.5 x ocular width; vertex punctures fine, puncture size = 0.33 x ocular facet diameter, separated by 2-3 x their diameter; epistomal punctures impressed, punctures size = 0.5 x ocular facet diameter, separated by 2-3 x their diameter; epistome anterior margin shallowly concave. Eyes large, coarsely faceted. Antennomere III length = 3 x width, length = length of antennomeres IV+V combined; antennomeres IV-VIII equal in length; antennomere IX triangular ( Fig. 25 View Figure 18-25 ), length = 0.8 x width; antennomeres X and XI equal in length; antennomere XI subcircular. Terminal maxillary palpomere triangular, symmetrical, length = width. Terminal labial palpomere triangular, asymmetrical, width = 2 x length, expanded medially, width = terminal maxillary palpomere ( Fig. 85 View Figure 85-88 ).

Pronotum transverse; punctures on disc evenly distributed, slightly finer than those on vertex; separated by 2-4 x their diameter; base with large punctures at each side of base, puncture size = 0.9 x ocular facet diameter. Scutellum pentagonal, length = 0.5 x width. Elytral striae puncture size = an ocular facet diameter, separated by 2-3 x their diameter; intervals with fine punctures; base lacking marginal bead. Wings present, fully developed.

Prosternum length = 2.5 x intercoxal width; sternal plate flat, roughened; sternal lines not continuous around coxal cavity, or with faint division; base shallowly concave. Mesosternal lines parallel, not continuous around coxal cavity. Metasternum long, distance between meso- and metacoxae = 1.8 x intermesocoxal width; anterior lines disappearing under mesosternum medially; continuous around mesocoxal cavity; punctures coarse, puncture size = mesosternal punctures, evenly distributed, separated by 2-3 x their diameter. Abdomen with coxal lines not connected medially; continuous around metacoxal cavity; first ventrite punctured like metasternum; ventrite II-V with finer punctures, evenly distributed; apex of ventrite V with coarse punctures. Male genitalia with flagellum having a dorsal cartilaginous thickening at the apical third and truncate apex ( Fig. 105 View Figure 105-120 ).

Distribution. This is the only Notaepytus species found on multiple West Indian islands: Bahamas (Cat Island, Eleuthera, New Providence), Cuba, Hispaniola, Tortue Island ( Fig. 1b View Figure 1 ).

Type Material. Lacordaire (1842) described variations which implies he had a series of specimens. Otherwise, he only stated the type(s) “Il se trouve à Cuba.” However, the name was originally used as a nomen nudum in the Dejean collection which Lacordaire studied and used in his monograph (see Materials and Methods). Type specimens of I. flavitarsis are probably within the Dejean collection at the MRSN or Lacordaire’s collection (present repository unknown). Dejean’s collection has a single specimen standing over a label stating “ Ischyrus flavitarsis Cuba Sturm, Dej. Lac.”. To fix the concept of the species to a single specimen, this specimen ( Fig. 148 View Figure 148-155 ) is here designated as the lectotype of Ischyrus flavitarsis . The label data are as follows: “/ [green paper] S. gago / LECTOTYPE Ischyrus flavitarsis Lacord. , det. P.E. Skelley 2008 /” (sex undetermined, MRSN).

Specimens Examined. A total of 211 specimens were studied. All label data are presented in the Appendix.

Variation. The only notable variation is the size of the orange elytral bands, which vary in size as much within a population as across the entire species range. These bands are present and distinct on all but one female specimen from Tortue Island, Haiti.

Remarks. Notaepytus flavitarsis is the most widely occurring species of the endemic West Indian fauna, and is expected to be found on other smaller island in the Caribbean.
