Type locality: Omilteme, Guerrero, Mexico, 8,000 feet (BMNH). 



"Remarks: Wagner's statement that the elytra of A. alticola are 

 the same as those of A. imitator is accepted hterally. The elytral 

 intervals of A. imitator are biserially pubescent. The apparently 

 long beak of this species should distinguish it from related forms. 



Apion {Trichapion) asellum Wagner 



Apion (Trichapion) asellum Wagner, Arch. Naturg. Berlin, vol. 78, p. 102, 1912. 



Description: This species was described from three males from 

 Managua, Nicaragua, one in the Wagner Collection and two in the 

 Solari Collection; this material was not seen by the author. The 

 following notes are a translation of the original description. 



Length, 1.7 to 1.9 mm. 



Near preceding species [godmani], of same body size and general 

 habitus, also same color; but has much larger and denser gray- white 

 pubescence on head, prothorax, and elytra; and denser pubescence on 

 ventral surface and folloAving characters: eye of male distinctly larger; 

 frons somewhat smaller, nearly smooth, indistinctly striate; eyes 

 beneath with snow white cilia. Beak slightly shorter than head and 

 prothorax combined, hardly curved; from above, base to antennal 

 insertion with wrinkled sculpture and single punctures, rather dull; 

 at antennal insertion slightly wider, from there to apex rather strongly 

 attenuate; with rows of punctures on both sides of smooth middle 

 line, gradually becoming finer toward apex; more shining and glabrous 

 toward apex; from side angulately swollen under the antennal 

 insertion, on dorsal line slightly angulate over antennal insertion. 

 Antennae inserted at distance equal to long diameter of eye, otherwise 

 much like godmani. The prothorax is larger in comparison to the 

 elytra, at the bisinuate base only one-sLxth wider than long, in front 

 with a slightly uniform constriction, the constriction before the hind 

 angle only a little stronger than that before the anterior margin and 

 rather less than the same in godmani; the punctation is distinctly 

 denser but finer and deeper, the interspaces smaller than the punctures; 

 the basal stria is rather short but deep. The elytra hardly differ, 

 a little wider and from the apex with less sinuation. The scutellum 

 somewhat larger, triangular, deeply grooved. The legs — especially 

 the femur — are similar in length but somewhat stouter; the first 

 tarsal segment distinctly longer and narrower than the second, which is 

 as long as broad; the claws are longer, widely spread, strongly toothed. 

 The male with the second and third pair of tibiae mucronate.
