INTRODUCTION

Currently, Apomecynini Thomson, 1860 includes 228 genera distributed worldwide (Tavakilian & Chevillotte, 2022), with more than 1,800 described species (Roguet, 2022). Of these, 44 genera and almost 380 species occur in the new world (Bezark, 2022b; Monné, 2022).

During the process of identification of specimens from the private collection of the first author, we found three new species of Apomecynini, one of them belonging to a new genus. Here we are describing these new taxa.

Adetaptera Santos-Silva, Nascimento & Wappes, 2019, includes 18 species distributed from southern United States of America to southern South America, including the Caribbean. Osckayia Pérez-Flores & Santos-Silva, 2021 remains known only by the type species, O. oaxacae Pérez-Flores & Santos-Silva, 2021, which occurs in the Mexican state of Oaxaca.

MATERIAL AND METHODS

Photographs of were taken by the second author with a Canon EOS Rebel T3i DSLR camera, Canon MP-E 65 mm f/2.8 1-5X macro lens, controlled by Zerene Stacker AutoMontage software; measurements were taken in “mm” using measuring ocular Hensoldt/Wetzlar - Mess 10 in the Leica MZ6 stereomicroscope, also used in the study of the specimens.

The collection acronyms used in the text are as follows:

Type material: Holotype ♀ from MEXICO, Oaxaca: Punta del Vigia (Puerto Escondido), 22-28.VI.2015, J. Rifkind leg. (CASC, formerly LGBC). The habitat (Fig. 4) of the collected specimen is coastal thorn forest, with mostly low, spiny vegetation just inland from the beach.

Etymology: The specific epithet “setigera,” is Latin and refers to the numerous elytral punctures equipped with short setae.

Remarks:Adetaptera setigerasp. nov. is similar to A. jejetama Gutiérrez & Santos-Silva, 2022 (see photographs of the holotype on Bezark, 2022a), but differs as follows: the lower eye lobes are narrower, with 4-5 rows of ommatidia; the elytral punctures are distinctly finer (no puncture wider than half the maximum diameter of the scape); and several elytral punctures have short, thick white setae. In A. jejetama, the lower eye lobes are wider, with 8-9 rows of ommatidia, the elytral punctures are strongly coarser, with some of them wider than half the maximum diameter of the scape, especially those just beyond the middle, and only a few punctures have short, thick white setae (none beyond the middle).

Type material: Holotype ♀ from MEXICO, Hidalgo: Hwy 105, 2.7 mi. N Tlanchinol, 5000’, 02.VIII.1982, C.W. O’Brien & Wibmer leg. (CASC, formerly LGBC).

Etymology: The species is named in honor of the late Charlie O’Brien, curculionid specialist in recognition for his contributions to taxonomic entomology, and willingness to provide material to the first author.

Remarks: Some features reported as generic turned out to be specific features of O. oaxacae Pérez-Flores & Santos-Silva, 2021. For example: the distance between upper eye lobes being greater than three times the width of one upper lobe (distinctly shorter in the new species); the lower eye lobes being about as long as the genae (longer in the new species); the antennae being longer than the body (about as long as the body in the new species) and the mesoventral process being longitudinally carinate (longitudinally sulcate in the new species); the elytra being granulate basally (not granulate in the new species). The antennal length is probably related to the sex. However, as only males of O. oaxacae are known and only a female of the new species is known, for now it is not possible to know the antennal length in the opposite sex of these species. Osckayia obrieni sp. nov. also differs from O. oaxacae by the elytra not having oblique dark bands contrasting with the remaining pubescence (oblique bands present in O. oaxacae).

Capaciphrynidius gen. nov.

Type species:Capaciphrynidius extensussp. nov., here designated.

Etymology: Latin, “capax” (wide), used in genitive case (capacis), plus the name of the genus Phrynidius (wide Phrynidius), allusive to the wide distance between the antennal tubercles. Masculine gender.

Description

Female: Moderately small sized; body strongly convex and widened; without long and erect setae. Head not retractile. Antennal tubercles distinctly more distant from each other than maximum diameter of scape. Antennae about as long as body, not strongly narrowed toward distal segments; without long and erect setae; scape subpiriform, without apical cicatrix; antennomere III longer than scape and antennomere IV. Eyes not divided or subdivided. Prothorax without lateral tubercles. Elytra sub-ovoid; irregularly, strongly tuberculate; humerus not strongly projected; apex rounded. Metathorax strongly reduced.

Remarks: The general appearance of Capaciphrynidius gen. nov. is similar to that of Phrynidius Lacordaire, 1869, but differs noticeably by the antennal tubercles being widely separated, as opposed to them being very close to each other in Phrynidius.

Type material: Holotype ♀ from HONDURAS, Lempira: 15 km SW Gracias, 21.III.1997, J. Prena leg. (CASC, formerly LGBC).

Etymology: The specific epithet “extensus” refers to the wide distance between the antennal tubercles, which distinguished the new species from members of the genus Phrynidius.

Remarks: Based on the similar general appearance of Capaciphrynidius gen. nov. with Phrynidius, probably the males are also very similar to females.

ACKNOWLEDGMENTS:

The first author would like to thank our colleagues for providing material for examination: Jacques Rifkind has given me many cerambycid specimens collected in various localities in Mexico; Ron Cave provided material from Honduras including the holotype of the new genus, and in years past, Charlie O’Brien gave me specimens in exchange for Neotropical weevils I had collected.
