- Meonochilus spiculatus
Diagnosis. Individuals of this species are best told by the narrow pronotal and elytral bases, resulting in a medially constricted body shape (Fig. 9 B). The suboviform elytra have deep, distinctly punctate striae and convex discal intervals with glossy surfaces. The antennae are moderately elongate, not submoniliform, with 9 th antennomere length 2.3 x maximum breadth. The male aedeagal internal sac bears a long, stout, spikelike flagellum, and the median lobe apex terminates in a narrow, symmetrically rounded bulblike tip (Fig. 2 F). This species exhibits a distribution parapatric to Meonochilus amplipennis in Bay of Plenty (Fig. 13, 15), but Meonochilus spiculatus can be easily diagnosed by its smaller body size-standardized body length 5.7 - 5.9 mm versus 6.1 - 6.9 mm-and through comparison of male aedeagal apices, Meonochilus amplipennis being characterized by an asymmetrical apicoventrally directed expansion (Fig. 2 A).
Etymology. The species epithet spiculatus is a Latin adjective with male ending denoting the apically pointed, spike-like flagellum of the male aedeagal internal sac.
