Abelater bosi is a species of the genus Abelater within the click beetle (Elateridae). The species was described in 2010 by Rainer Schimmel and Dariusz Tarnawski using a collection of beetles in a forest area on the Indonesian island of Sulawesi and named after the Dutch zoologist Merijn M. Bos.
features
Abelater bosi is only known from males, female beetles have not yet been detected. It is an elongated, wedge-shaped and slightly arched beetle with a body length of 4.4 millimeters and a maximum width of 1.2 millimeters. It is two-tone yellowish-brown with black eyes, scutellum and a small central groove (striae) on the pronotum and the elytra . The antennas are solid yellow.
The head is densely dotted with circular dents, the gaps are reduced to small folds. The hair is short and decreases towards the top and the sides. The eyes are slightly spherical and slightly protruding. The antennae have bristle hairs, consist of 11 segments and, when put back, protrude beyond the rear edge of the pronotum by the length of the last antennae. The second and third antennas are short and cylindrical, both together are significantly shorter than the very long fourth and also each of the following antennas. The fifth to tenth antennas are each shorter than the fourth antenna, they are spindle-shaped and slightly keeled in the middle. The last antenna is rectangular-ovoid and bevelled just before the tip.
The pronotum is bell-shaped and the length at the midline is 1.17 times longer than the width at the trailing edge. It is slightly arched and slightly beveled at the sides, it widens at the base. The posterior corners of the pronotum are pointed and slightly diverging. It has dense stippling with flat spaces. The hair is short and brush-like and hardly visible, it decreases towards the middle and to the sides. The pro, meso and metathorax are also densely punctured, the spaces in between are slightly raised. The scutellum is flat and wedge-shaped, slightly arched at the base and pointed at the ends. The top is flat with fine dots, the areas in between are three to four times as wide as the diameter of the dots. The legs are slender, of medium length and thin, the femur is thickened and the tibiae are short and rigid bristles. The tarsus consists of five tarsomeres that decrease in size and have a simple claw.
The wing covers (elytres) are wedge-shaped and flat, after the first third they narrow towards the rear end. The ends are slightly arched with an inner tooth. The base of the elytra is slightly narrower than the pronotum, it is flat and slightly indented on the scutellum. The front area is slightly arched and raised to shoulders by the wings below . The grooves of the elytra have simple and wrinkled dots, the elevations are finely dotted. The aedeagus , the male reproductive organ, has a species-specific shape with a thickened median lobe that clearly reaches the ends of the paramers.
Abelater bosi corresponds in its appearance to Abelater pusillus , but can be distinguished from it due to the central black striae on the pronotum and the elytra. It differs from Abelater dongalaensis , who was described together with A. bosi , in that it has longer antennae, the dense puncturing of the pronotum and the shape of the aedeagus.
Distribution and way of life
There is no information about the way of life of the species. The holotype was collected from a collection after foliage fumigation in a cocoa plantation in the center of Sulawesi Island in Donggala in the Sulawesi Tengah province . The area is about 750 to 1000 meters above sea level.
Systematics
Abelater bosi was described as a separate species of the genus Abelater within the click beetles (Elateridae). They named the first descriptors Rainer Schimmel and Dariusz Tarnawski after the collector of the holotype, the Dutch zoologist Merijn M. Bos. Schimmel and Tarnawski received the holotype for identification as part of a collection by Boris Büche from Berlin and, in addition to Abelater bosi, described eight other species of the tribe Megapenthini from this collection as part of the first description. Another species from the collection named after Bos is the flea beetle Argopistes bosi in 2011.
