Apion (Trichapion) persulcatuni "Wagner 



Apion ■persulcaium Wagner, M^m. Soc. Eut. Belgique, vol. 19, p. 22; pi. 2, figs. 

 3a, 3b, 1911. 



Description: This species was described from a male in the 

 Wagner Collection and a pair in the British Museum (Natural 

 History) that were not seen by the author. The following notes 

 are taken from the original description. 



Length, 2.8 to 2.9 mm. 



Close to Apioit snbnudum "Wagner [which does not seem to belong 

 to the subgenus lyichapion]. The body is black, onh'- slightly 

 shining, the elytra are bright as in suhnudum but ai'e more grayish 

 blue. Beak in both sexes distinctly longer than subnudum and of 

 the female more slender, about one-thu-d longer than head and 

 prothorax combined, of the male somewhat shorter; in both sexes 

 somewhat more curved than subnudum. The prothorax is somewhat 

 shorter than suhnudum, sides between hind angle and anterior margin 

 uniformly rounded; with large, shallow punctures rather densely 

 placed, microscopically fineh' chagrined interspaces not v.-ider than 

 pmictiu-es; with a rather strong, short basal fovea. Elytra behind 

 well developed humeri strongly widened posteriorly, widest behind 

 the middle. Scutellum like subnudum. The tarsi are more slender; 

 the first segment of the front leg is about one-half longer and narrower 

 than second; the fom* posterior legs are shorter; the last two pairs 

 of legs of the male are mucronate. 



Known distribution: 



Guatemala: Capetillo; Retalhuleu.

Apion (Trichapion) spiculiferum Wagner, Arch. Naturg. Berlin, vol. 78, p. 104, 1912. 



Description: This species was described from a few specimens in the 

 British Museum (Natural History) that were not seen by the author. 

 The following notes are taken from the original description. 



Length, L9 to 2.2 mm. 



Closely related to A. aurichalceum Wagner, which has a larger body 

 and bright sheen and gloss, finer, sparser pubescence especially on the 

 beak. Female beak a little longer than head and prothorax, strongly 

 curved, brightly shining, with single, fine punctures, a little denser 

 over the antennae; male beak somewhat shorter than that of female,
