( Fig. 11 , 20)

Type material. Holotype, male. Costa Rica, Cartago, Turrialba –CATIE, May 28–31, 1987, E. Giesbert, coll . Holotype deposited in CSCA . Paratype: 1 ( JNRC), Costa Rica, Cartago Prov., Turrialba, 2–8 June, 1967, coll. J. Robertson.

Diagnosis. Quadrophenia daltreyi can be distinguished from congeners by its uniquely colored elytra: concolorous, pale sorrel brown with a slightly olive, pearlescent cast ( Fig. 11 ). It can be further separated from sympatric individuals of Q. mooni by its bicolored antennae and darkened tibiae, and from unmarked sympatric individuals of Q. townshendi by its bicolored antennae.

Description. (Holotype). Length: 9.25 mm. Form: slightly subflattened dorsally, moderately expanded posteriorly. Color: orange-testaceous; cranium, mandibles, genae, anterior gula, and tibiae piceous; antennomeres 4–8, metasternum and tarsi, dark brown; elytra uniformly pale sorrel brown with a slight olive cast. Antennae: terminal antennomeres with internal and external / distal emarginations exaggerated, apex subacuminate ( Fig. 20). Pronotum: disk smooth except for a few scattered setae; sides shallowly, feebly rugulose. Elytra: nearly 2× as long as wide; slightly expanded posteriorly, broadest just posterior to middle; surface rather coarsely, moderately densely but shallowly punctate; asetiferous punctures most conspicuous on anterior disk on either side of suture; pubescence inconspicuous, composed of erect, rather robust black setae, intermingled with shorter, suberect black setae, and very few suberect pale setae. Integument with a slight pearlescent luster. Abdomen: ventrite 5 with the hind margin shallowly, broadly emarginate; ventrite 6 smaller than ventrite 5, its sides oblique and hind margin slightly emarginate; tergite 6 with sides slightly obliquely convergent, posterior margin rather broadly subtruncate.

Variation. The single paratype, a female, differs as follows: length 10.25 mm; metasternum orangetestaceous; abdominal ventrite 6 with hind margin subtruncate.
