Description. Body length 1.08–1.18 mm, width 0.70–0.81 mm, oval, relatively flat in lateral view (2.08 times as long as thick). Color dark yellow without metallic luster, legs slightly darker and antennae dark brown, almost black. Vertex covered with large punctures, shiny, without wrinkles. Oblique fold situated between orbit and antennal callus. Proportions of antennomere lengths in female: 13:8:7:5:4:4:5:5:6:8:11. Antennomeres widened abruptly beginning from antennomere 7 (it is as long as wide). Pronotum evenly covered with large punctures, their diameter much larger than distance between them. Anterolateral callosity extending slightly beyond lateral margin. Ventral side of body without many setae. Elytron with nine complete rows of punctures, additional scutellar row with six punctures. Punctures large, about as large as space between rows. Interspaces convex, shiny, without wrinkles or punctures. Proportions of tarsomere lengths of female as follows: protarsomeres 7:6:6:14; mesotarsomeres 7:6:6:14; metatarsomeres 10:6:6:13. Spermathecal receptacle separated from pump and as long as pump. Receptacle ovoid, sides convex. Duct without coils, making a loop away from receptacle, its longitudinal part straight. Tignum long, its narrow part slightly curved, posterior part widely sclerotized. Sclerotization fades posteriorly. Vaginal palpi widely separated posteriorly. Free (posterior) part slightly longer than anterior.

Remarks. Borinken toronegro differs from B. elyunque by the dark yellow color ( B. elyunque is dark brown, Fig. 1 – 3 ). In B. toronegro the antennae are much darker than the body (in B. elyunque the antennae are about the same color as the beetle body). Elytral interspaces are a bit more convex in B. toronegro . In addition, B. toronegro may be separated from B. elyunque by the following features: anten- nal calli positioned more or less horizontally (more or less vertically in B. elyunque ); pronotum slightly wider ( Fig. 1 , 4 ); anterolateral corners of pronotum extend farther beyond lateral margin (anterolateral corners of pronotum extend not as far beyond lateral margin ( Fig. 1 , 4 ).

Habitat. Borinken toronegro was collected at the highest point of Puerto Rico, near the phone towers on Toro Negro. Moss bearing trees are located on the side of the road that leads to the towers ( Fig. 20, 21 ).

Distribution. Puerto Rico.

Etymology. This species is named after its type locality. The epithet is a noun in apposition.
