Male ( Fig. 7 ). Head, excluding mandibles, as long as or slightly shorter than prothorax, slightly elongated behind eyes. Central area between antennal tubercles and middle of upper ocular lobes with gibbosity on each side of longitudinal dorsal furrow. Dorsal face with coarse punctures, densely and confluent laterally, finer and sparser towards the longitudinal furrow (occasionally with irregular subsmooth area between posterior ocular edge and occiput). Area behind eyes coarsely and confluently punctate close to dorsal face, rough in region between ocular lobes, and rugose toward base of lower ocular lobe. Antennal tubercles rounded to subconical. Clypeus short (approximately 0.25 times width), rugose-punctate with central longitudinal depression, and distinctly elevated laterally. Labrum sub-vertical (only lateral areas visible dorsally). Eyes large; distance between upper ocular lobes from 1.8 to 1.9 times length of scape; distance between lower ocular lobes from 2.0 to 2.3 times length of scape. Ocular carina narrow and distinct. Hypostomal area uniformly depressed from gula to mentum ( Fig. 25 ), generally slightly more marked at central region close to anterior edge; setation sparse. Hypostomal carina elevated ( Fig. 25 ). Maxillary palpomere III as long as IV. Apex of labial palps attaining approximately apex of maxillary palpomere III. Galea not reaching apex of maxillary palpomere II.

Mandibles ( Fig. 7 ) as long as the head (minor males) or longer (major males); dorsal carina ( Fig. 40 ) strongly elevated at base, forming tooth, gradually sloped from tooth to level of inner apical tooth, and abruptly sloped (major males), or gradually lowered from apex of tooth to area of abrupt declivity (minor males); inner margin with two large teeth together protracted (minor males) or with large tooth before middle and small tooth near inner apical tooth (major males). Antennae not attaining middle of elytra; scape coarsely punctate.

Anterior angles of prothorax not spiniform, projected forward; lateral angles subspinose; posterior angles obtuse or rounded. Elytra finely punctate; elytral carinae distinct. Metepisternum ( Fig. 59 ) notably narrowed and concave at inner margin (width at central region 0.05 times length). Genitalia ( Figs. 68, 72 ).

Dimensions in mm (male). Total length (including mandibles), 39.2–45.7; prothoracic length, 5.5–6.6; anterior prothoracic width (between apices of anterior angles), 8.8–10.2; posterior prothoracic width (between apices of posterior angles), 8.9–10.2; humeral width, 10.9–12.0; elytral length, 23.8–26.0.

Types, type-localities. Of Prionus subsulcatus : holotype male (photograph examined), from Honduras, deposited at NHRS.

Of Mallodon gnatho : holotype male (photograph examined), from Honduras, deposited at BMNH.

Of Nothopleurus ebeninus : holotype male, from Mexico (Yucatan), deposited at CMSP.

Geographical distribution ( Fig. 78 ). Recorded from Honduras ( Dalman 1823), Mexico ( Lacordaire 1869) and Guatemala (Monné 1995). Recorded for the first time to Bahamas.

Material examined. BAHAMAS, Hope Town: Man-of-War Cay, 2 males, V.9.1986, Feller & Ryan col. ( EMEC).

Comments. Males of N. subsulcatus are distinguished from those of other species of the genus by the unique large tooth on the mandibular carina or, at least having it strongly elevated at its base.
