( Fig. 43 )

Lasiochilus ashlocki Herring, 1966: 128 .

Dilasia ashlocki: Carpintero, 2002: 27 .

Diagnostic characters: Measurements, see Table IV. Easily distinguishable from all others by its coloration, hemelytra dark brown with base of clavus and corion pale yellowish and by the short head as well as its measurements. Antennal segments (I:II:III:IV) ♀ 1: 2.1: 1.8: 1.7.

Distribution: Coco Is. ( Costa Rica). ( Fig. 48 )

Material examined: Allotype COSTA RICA: ♀ Coco Is. Chatham Bay, 8-III-1964. (P. D. Ashlock). USNM.

Discussion. The author had no opportunity to clear specimens because of the lack of additional material. However, he has no hesitation in placing this species in Dilasia because of texture of the hemelytra, the absence of strong punctures with emerging setae, the apically thickened second antennal segment, that is shorter than the head, the labium’s reaching the midcoxae and the typically Dilasia shaped the pronotum and head.
