No full textMecodema ponaiti, sp. n. Figures: 5, 9 b, 11 b, 13 a, 25 a. Diagnosis. Head broad but convex. Clypeus with a single setose puncture on each side, bearing 2 setae. Prothoracic carina broad, crenulation absent and extended to anterior angle. Pronotum fovea shallow and narrow. Elytral striae with regularly distributed, small asetose punctures. Setose punctures absent on 3 rd, 4 th and 5 th ventrites. Apical portion of aedeagus symmetrically rounded with a strong twist to right of vertical. Dorso-apical portion of central spicule, greatly expanded. Basal lobe of left paramere rectangular, arm and apical lobe relatively large, and with setation along apical ¾ of ventral edge. Description. Length 20–26 mm. Colour black. Head broad but convex. Microsculpture of frons and vertex absent. Vertexal groove broad laterally and narrow middle. Form of microsculpture on anterior area of clypeus, spatulate. Clypeus with single setose puncture on each side, bearing 2 setae (or 2 setose punctures on each side bearing a single seta each*). Form of lobes of the mentum, square. Submentum constriction broad, with 6 setae. Prothoracic carina broad, crenulation absent, and extended to anterior angle (or extending to beyond anterior angle*). Pronotum broad and flat, posterior lateral sinuation angle parallel, pronotal fovea shallow and narrow, microsculpture of pronotal disc absent. Elytra broad but convex, striae with regularly distributed small asetose punctures, intervals slightly convex. Setose punctures of mesocoxae present, absent metacoxae. Setose punctures absent 3 rd, 4 th and 5 th ventrites. Apical portion of aedeagus symmetrically rounded with a strong twist to right of vertical axis. Dorso-apical portion of central spicule, greatly expanded. Left paramere basal lobe rectangular, arm and apical lobe relatively large, and with setation along apical ¾ of ventral edge (or setation along apical ½ of ventral edge*). Comments. Britton (1949) placed specimens from the Poor Knights Islands and Whangarei area under M. atrox, which seemed to be the “default” species for Northland specimens. M. ponaiti is sister species to the remaining curvidens species and is endemic to the Poor Knights Islands. The similarities between the M. ponaiti and M. manaia species can be seen in one of the two variants of the island group. The variant from Aorangi Is. has similar external morphological features to those of M. manaia (Whangarei Heads), whereas the Tawhiti Rahi Is. variant exhibits similarities in external morphology to M. regulus (Three Kings Islands), especially the pronotal disc, which is more rounded laterally than the mainland species. In the description the difference in character states between the two variants are indicated by an asterisk (*). Several specimens of M. ponaiti have been collected in association with seabird burrows, either resting under logs in close proximity or from within the burrows themselves. Distribution.

The Poor Knights Islands are within the Ngatiwai rohe and as Ngatiwai have no collective name for the Poor Knights Islands, they requested that the species be named ponaiti (pona-iti), which is a trans-literation of the name of the islands.Published as part of Seldon, David S. & Leschen, Richard A.

This is the first described carabid species endemic to Little Barrier Island, the other 16 native carabid species on the island are also found on the mainland. Little is known of their ecology or biology; however, specimens have been mostly collected throughout the summer months in mature mixed kauri (<i>Agathis australis</i>) / broadleaf forest and usually in relatively close proximity (within 100 m) to freshwater. Additional specimens have been found in dry stream beds, and burrows of seabirds.</p> <p> <b>Distribution.</b> North Island: CL, Little Barrier Island (only).</p> <p> <b>Holotype:</b> Male labelled NEW ZEALAND CL, Little Barrier Island, Tirikakawa Stream, 2005, D.S.

The holotype is male, with the genitalia contained in a silicon genitalic tube and pinned with specimen. Most specimens have been found in relatively undisturbed, mature native broadleaf forests that range from coastal to the highest points (600 m) of the island. <i>Mecodema aoteanoho</i> is the first described carabid species endemic to Great Barrier Island and is the sister species to <i>M. haunoho</i> (Little Barrier Island).

The difference between the two species is that <i>M. parataiko</i> has larger and more strongly impressed asetose punctures distributed in a confused pattern along the elytral striae. These two species form a monophyletic group nested in the Northland basal elements of the group. <i>M. parataiko</i> is the most widespread of the species found in Northland.</p> <p> <b>Distribution.</b> New Zealand, North Island, Northland (ND), Parataiko Range, Warawara Forest, Tangihua Range, Omahuta F.P., Mangamuka S.R., Herekino Forest and Ahipara Plateau.</p> <p> <b>Holotype:</b> Male labelled (NZAC) NEW ZEALAND ND Mangamuka Gorge Wkwy 350m 351140S/1732725E 17.IX.–16.X.1999 Larivière.

Clypeus with 2 setose punctures on each side, anterior with single seta, posterior with 2 setae. Prothoracic carina broad, heavily crenulated, and extended to anterior angle, pronotum fovea deep and narrow. Elytral striae with regularly distributed, small asetose punctures. Setose punctures absent on 3rd ventrite, present on 4th and 5th ventrites. Apical portion of aedeagus symmetrically rounded with a moderate twist to right of vertical. Dorso-apical portion of central spicule, not greatly expanded. Basal lobe of left paramere rectangular, arm and apical lobe relatively small, and with setation along apical ½ of ventral edge.</p> <p> <b>Description.</b> Length 25–27 mm. Colour black. Head broad and flattened. Microsculpture of frons and vertex absent. Vertexal groove narrow, defined entire length with V-shape at midpoint. Form of microsculpture on anterior area of clypeus, poorly defined. Clypeus with 2 setose punctures on each side, anterior with single seta, posterior with 2 setae. Form of lobes of the mentum, square. Submentum constriction broad, with greater than 6 setae. Prothoracic carina broad, heavily crenulated and extended to anterior angle. Pronotum broad and flattened, posterior lateral sinuation angled slightly inward, pronotal fovea deep and narrow. Elytra broad and flattened, striae with small regularly distributed asetose punctures, intervals slightly convex. One setose puncture present on mesocoxa and metacoxa. Setose punctures absent on 3rd ventrite, present on 4th and 5th ventrites. Apical portion of aedeagus symmetrically rounded with a moderate twist to right of vertical axis.

However, the presence of setose punctures on the 4th and 5th ventrites, crenulation of the prothoracic carina and pronotal posterior sinuation, and the anterior extention beyond the anterior angle show <i>M. tenaki</i> also shares similarities with <i>M. manaia</i> (Whangarei area).

Comments: Mecodema manaia shares similar morphological characters with M. tenaki (Cape Reinga) and M. regulus (Three Kings Islands), and although there is suitable forest habitat along the eastern coastline to the north, no specimens have been collected from these areas.
