Subgenus Deranchylaeus Bridwell, 1919

Hylaeus subgenus Deranchylaeus Bridwell, 1919: 136–137 . Type species: Prosopis curvicarinata Cameron, 1905 by original designation.— Sandhouse 1943: 544; Snelling 1985: 6–8; Michener 1997: 19; Michener 2000: 193, 195; Eardley & Urban 2010: 26.

Characters

(1) Small to middle-sized species (TL 4.0– 6.5 mm), with integument frequently coarsely punctate.

(2) Supraclypeal area usually bounded laterally by two fine outwardly curved carinae.

(3) Pronotum broadened, mostly laterally expanded, often carinate in front and with lateral edges pointed.

(4) S7 of the male with four apical lobi, the distal ones without setae, the proximal ones often with a row of setae, lamellae or teeth; S8 has mainly a blunt apical process. The basic pattern of the typical curvicarinata-group is shown in Figs 5–7 : distal lobi of S7 are formed as small flags, the proximal ones each with a largely marginal row of coarse setae.
