Hyperstoma is a genus of firefly beetles in the family Lampyridae. [1] Previously considered as a monotypic genus, the second species of the genus was described in 2011. [2] The genus is endemic to Sri Lanka. [3]
The genus is closely related to the genera Lamellipalpus and Lamellipalpodes due to having fused terminal and penultimate terga. [4] [5] [6]
Body length is about 5 to 5.5 mm. Body is oval, with ranges from yellow to light brown in color. The terminal maxillary and labial palpomere are extremely long. Males possess flabellate antennae with stout branches attached to the apex of antennomere. The terminal and penultimate abdominal terga of the male is also fused, and jointly trilobed. The distal portion of the antennae and elytral margins are dark brown. Eyes are small. Antennae consists with 11 segments, where 3 to 10 antennomeres are flabellate with strongly flattened lamellae. Mandibles are small, hooked, and apically pointed. Maxillary palpi with 4 segments, whereas labial palpi with 3 segments. Pronotum yellowish to light brown in color with almost straight anterior margin, rounded anterior angles, and triangular posterior angles. Scutellum triangular, and color ranges from yellow to light brown. Elytra elongate, with wide medially, with rounded apex. Elytra shiny, and irregularly densely punctured. Male genitalia possess a V-shaped phallobase, robust paramerae with rounded apex. Phallus cochleariform. [4]

Though relatively rare, males are sometimes found in large numbers in black light traps. Females are not known in this group, but it is theorized that females are larviform as found in many closely related taxa.

Perothops is a genus of false click beetles in the family Eucnemidae containing 3 species. They are known as beech-tree beetles or perothopid beetles. They are small as they are only 10–18 millimeters long. It is the only genus in the monotypic subfamily Perothopinae. They are dark-colored beetles that are found across the United States, generally in forests. The genus was discovered by Johann Friedrich von Eschscholtz in 1836. It used to be considered a family not part of Eucnemidae. The genus's name is from Greek, translating to "maimed/crippled eye" or "eye of little necklaces/bands", referring to the placement of perothopid eyes.
