Type material. HOLOTYPE: ♀, “4168. ♀. / Waimarino Jany. 1909 / New Zealand [with red underline] Broun Coll.Brit. Mus. 1922-482./ Euglyptus longiceps . ♀ / [white label] HOLOTYPE Euglyptus longiceps Broun ’17 det. DSChandler” ( BMNH, NHMUK015534119 ).

Comments to classification. This species was identified using photographs of the type specimen deposited in the National History Museum in London. According to the original description, E. longiceps is similar to E. sublaevis but differs in the color of the elytra, elytral carinae, and the shapes of the head and thorax, and it has smaller eyes. When compared to E. costifer it has larger eyes and body size, with noted differences in the joints of the antenna and leg. Photographic comparisons show that E. longiceps has larger eyes than E. costifer , along with slight morphological differences. The punctures on the prothorax appear slightly larger in E. costifer , and while the temples narrowing toward the posterior margin, in E. longiceps is somewhat straight, whereas in E. costifer is slightly rounded. The small eye size is a characteristic of females in the genus Euglyptus , which corresponds with this species being described as a female. This evidence suggests that E. longiceps is a different species from E. elegans (= E. costifer ) and E. sublaevis . As the type specimen of E. longiceps was not physically favorably compared with the material at hand, its taxonomic status remains unchanged. To accurately place this species, additional collections from the type locality together with morphological comparisons and anatomical study of the types are needed to be certain of placement.
