Adelothyreus costaricensis Otto, Muona and Córdoba-Alfaro , new species
Figures 13–16 View Figures 10–16
Diagnosis. This new species is very similar to A. comes . The posteroventrally directed anterior lateral pronotal ridge will distinguish the new species from A. comes .
Type material. Male holotype: “ COSTA RICA: Heredia; Est.Bio. La Selva, 50–; 150 m 10°26′N 84°01′W; Proy. ALAS, INBio-OET” / “M/01/332; 01 Febrero 1994; Parcelas sucesionales” / “ HOLOTYPE:; Adelothyreus ; costaricensis ♂; Otto, Muona & Córdoba-Alfaro; Det. R. L. Otto; 2019” (red printed label). Female allotype: “ COSTA RICA, Heredia; Est.Bio. La Selva , 50–; 150 m, 10°26′N 84°01′W; Proy. ALAS, INBio-OET” / “M/15/121; 02 Junio 1993; Bosque secundario” / “ ALLOTYPE:; Adelothyreus ; costaricensis ♀; Otto, Muona & Córdoba-Alfaro; Det. R. L. Otto; 2019” (yellow printed label).

Description. Male holotype: Length, 2.5 mm. Width, 0.75 mm. Body elongate; uniformly dark black; antennae dark brownish black; femur and tibiae dark brownish black; tarsi dark brown; head, pronotum and elytra clothed with short, recumbent yellowish setae ( Figure 13 View Figures 10–16 ). Head: Surface densely punctate, somewhat dullish, subspherical; frons convex, without median fovea or carina; apical margin of frontoclypeal region rounded, more than 2.0 times wider than base; mandibles stout, bidentate, densely punctate. Antenna: Pectinate from flagellomeres II–VIII, attaining about 2/3 the length of the body; flagellomere I longer than II; flagellomeres II–III sub-equal, each shorter than IV; flagellomere IV longer than III, shorter than V; flagellomeres V–VIII each sub-equal, longer than wide; flagellomere IX longer than VIII; ramus on flagellomere II arising along entire length, rami on flagellomeres III–VIII arising at apical end, elongate and about 1.5 times longer than length of segment. Pronotum: Surface somewhat dullish, closely punctate; longer than wide, with poorly developed hind angles; lateral sides parallel-sided, apically arcuate; disc convex without median groove; anterior lateral pronotal ridge short, arcuate, directed posteroventrally; posterior lateral pronotal ridge elongate, about 3/4 the length of the pronotum ( Figure 14 View Figures 10–16 ); base sinuous, with circular strong impressions above scutellar shield. Scutellar shield: Short, quadrate, sub-triangular, shallowly punctate, setose and distally rounded. Elytra: Very shallow striate indicated; interstices slightly elevated; surfaces shiny, very closely punctate to rugose at basal 1/2, closely punctate at apical 1/2. Legs: First tarsomere as long as the combined lengths of the remaining four on meso- and metatarsi; tibiae rounded in cross section; metatarsomeres I–III simple; metatarsomere IV very short, excavate; metatarsomere V short with simple claws. Venter ( Figure 15 View Figures 10–16 ): Closely punctate, with short, recumbent yellowish setae; hypomeron with apically widened notosternal antennal grooves; antennal grooves smooth, sparsely punctate; metepisterna caudally wide; elytral epipleura punctate; metacoxal plates parallel-sided.
Female allotype ( Figure 16 View Figures 10–16 ): Length, 3.0 mm. Width, 1.0 mm. Antennae serriform, about 1/2 the length of the body; flagellomere I longer than wide, longer than II; flagellomere II quadrate, serrate, shorter than III; flagellomeres III–VIII sub-equal, transverse, asymmetrically serrate; flagellomere IX longer than VIII.
Distribution. This species is only known from its type location in Costa Rica.
Biology. The holotype was taken from a successional plot of trees. The allotype was taken from a secondary growth forest. Larvae and pupae are unknown.
Etymology. The specific epithet is named for the country of Costa Rica from which the new species was taken.
