Apion (Trichapion) brachycephalum Wagner, Arch. Naturg. Berlin, vol. 78, 

 p. 109, 1912. 



Description: Length, 1.94 mm. 



Moderately robust. Black, with slight brassy luster, antennae 

 piceous; pubescence white, on dorsal surface of prothorax and elytra 

 very fine and sparse, coarse and dense on sides of mesothorax and 

 metathorax. Male beak stout, shorter than head and prothorax 

 combined, one-fifth longer than prothorax, moderately strongly, 

 evenly curved; in lateral view very slightly attenuate to tip; in dorsal 

 view slightly expanded at antennal insertion, attenuate to apical two- 

 fifths, tip slightly expanded; with dorsal median, narrow, impunctate 

 line extending from base to apical two-fifths, at basal two-fifths dilated 

 into a diamond-shaped ridge thence attenuating to a fine, raised line; 

 slightly shining, laterally with several rows of coarse punctures, tip 

 smoother, pubescent to near tip. Antennae inserted at distance from 

 eye equal to width of frons; first segment equals next two, second 

 segment shorter than next two, club 0.24 by 0.09 mm. Ej-es moder- 

 ately prominent; frons narrow, as wide as dorsal tip of beak, with a 

 shallow, wide, median sulcus, top of frons with several coarse punc- 

 tures. Prothorax at base one-fourth wider than long, middle narrower 

 than base, apex three-fourths as wide as base; sides beyond basal 

 lateral expansion rounding to constricted apex; in profile dorsal surface 

 is nearly flat; punctation on dorsal surface moderately deep, 0.03 to 

 0.04 mm. in diameter; interspaces irregular, narrower than diameter 

 of punctures; basal fovea moderatelj^ deep, punctiform. Elytra at 

 humeri one-third wider than prothorax at base, 2.5 times as long as 

 prothorax, length to width as 10 : 7.5; mtervals nearly flat, twice as 

 wide as striae, with a single row of fine punctures bearing fine scales; 

 striae deep. ScuteUum triangular, 0.12 by O.OG mm. Front femora 

 three times as long as wide. Claws with acute basal tooth. 



Special male characters: Tibia 2 armed with short, blunt mucro; 

 tibia 1 with anterior inside surface bearing polished, nonstriate 

 area; first segment of tarsus 1 with inner margin produced into a 

 short spine. 



Material examined: One male determined as a female by Hans 

 Wagner. 



Known distribution: 



British Honduras: Belize and Blancaneaux (BMNH). 

 Guatemala: Zapote (BMNH). 



Remarks: There is some question regarding the correctness of 

 Wagner's determination of the specimen seen. The species was
