Diagnosis. Antillengis brunnipes is recognized by its smaller body size (less than 9 mm long), triangular mental plate, and narrow, well-defined gular-submental groove.

Description. Length = 7.5-8.4 mm; width 3.7-4.3 mm. Body dark reddish-brown nearly black; antennae, palpi, legs, and apical 4 abdominal ventrites reddish-brown; elytral apex with red-brown mark which extends laterally and anteriorly nearly to middle ( Fig. 35 ).

Head with base coarsely punctate, puncture size = an ocular facet diameter, separated by 0.5-1.0 x their diameter; vertex and epistomal punctures = 0.3 x ocular facet diameter, separated by 2-4 x their diameter on vertex, becoming denser on epistome. Mentum transverse, plate width = 2.0 x length, plate triangular with anterior margin angled, narrowly rounded medially. Gular-submental groove narrow, well defined; except for few punctures laterally, gula lacking sculpture posterior of groove.

Pronotal lateral margin straight at base, evenly arched toward eyes anteriorly. Elytra strial punctures large, distinctly impressed, slightly larger than coarse punctures at base of pronotum; intervals finely punctate, puncture size = fine pronotal puncture.

Prosternum with marginal bead broad and well defined medially, becoming narrow and weakly defined laterally; anteriorly coarse lateral punctures not attaining midline. Genitalia similar to A. epochthidius (as in Fig. 33-34 ).
