Opselater is a genus of click beetle (family Elateridae). They are one of several genera in the tribe Pyrophorini, all of which are bioluminescent. [2] This genus was established by Cleide Costa  [ species ] in 1975. [1] After a revision of the genus by Simone Policena Rosa  [ species ], [3] she stated some members of this genus are polyphyletic with Lygelater bifossulatus  [ species ](Candèze, 1865), which discouraged her from establishing any new genus in this part of Pyrophorini due to alternative resolutions and ambiguity. [4]

Description

Small; dark-brown. Pubescence short, dense yellowish or grey. Eyes in males slightly more developed than in females. Front prominent. Antennae reaching the hind angles of the prothorax, serrate from fourth segment onwards; third segment little longer than second, the two together of the same length of the fourth. Prothorax slightly convex, punctures variable. Luminous spots small, lateral, flat and visible also in the proepisternum. Mesosternal cavity sinusoidal and a little raised behind. Metacoxal plates little enlarged inwardly. Abdominal luminous organ small and lamellate. Elytral sides subparallel and rounded to apices. Male genitalia: median lobe very enlarged at the middle, with or without minute cuticular scales. Female genitalia: bursa copulatrix more or less spiraled, with long spines; accessory glands well developed; spermatheca well developed and median oviduct with sclerotized plates. [1]

Range

Opselater is mainly distributed in the Atlantic forest and some species are apparently disjunct. [5]

<i>Pyrophorus</i> (beetle) Genus of beetles

Pyrophorus is a genus of click beetle. They are one of several genera in the tribe Pyrophorini, all of which are bioluminescent. Their bioluminescence is similar to that of another group of beetles, the fireflies, although click beetles do not flash, but remain constantly glowing. They have two luminescent spots at the posterior corners of the pronotum, and another brighter light organ on the most-anterior surface of the ventral abdomen. This light organ is even brighter and can only be seen when in flight. Bioluminescent click beetles are found throughout tropical, subtropical and temperate America. Species from Texas, Florida, Puerto Rico, and Cuba are now in different genera in the tribe Pyrophorini, such as Deilelater and Ignelater.

<i>Ignelater luminosus</i> Species of beetle

Ignelater luminosus is a bioluminescent species of click beetle native to the island of Puerto Rico, one of several Caribbean species in the genus Ignelater that are known as cucubanos. Cucubanos are often confused with fireflies, which are in a different family (Lampyridae), but they emit light from the thorax, unlike true fireflies. Their paired prothorax light organs and single light organ on the anterior surface of the abdomen gives the appearance of two "headlights" and one "backlight", which it can turn off independently.
