Additional material. Northland (15 examples, 4 exx. dissected): Puketi State Forest; Russel State Forest; Waiorio Bush, Kawakawa; Mair Park, Whangarei; Parahaki Park, Whangarei.
Auckland (4 examples, 2 exx. dissected): Cascades; Oratia; Huapai; Little Barrier Pohutukawa Flat.
Specific epithet. The specific epithet is a Latinized eponym in the genitive case, and is based on the surname of B. P. Moore, the first reviser of the species of Anillina of New Zealand.
Type locality. New Zealand, North Island, Northland, Poor Knights Islands.
Recognition. Adults of this species (Fig. 5 D–E) are practically indistinguishable externally from the adults of other congeners, except the smaller size and lighter color, and males of P. m o ore i are distinguished from the males of other congeners by the structure of the median lobe.
Description. Size. Small- to medium-sized for genus (SBL range 1.18–1.50 mm, mean 1.38± 0.089 mm, n=21).
Habitus. Body form subdepressed, subparallel, markedly elongate (WE/SBL 0.36±0.013), head large for genus compared to pronotum (WH/WPm 0.80±0.018), pronotum of moderate width in comparison to elytra (WPm/WE 0.79±0.024).
Color. Body color rufotestaceous, appendages testaceous.
Prothorax. Pronotum (Fig. 6 C–D) moderately long (LP/LE 0.45±0.018) and moderately elongate (WPm/LP 1.19±0.053), with lateral margins shallowly sinuate and markedly constricted posteriorly (WPm/WPp 1.51±0.036). Anterior angles prominent, posterior angles almost rectangular (90–110°). Width between anterior angles much greater than between posterior angles (WPa/WPp 1.22±0.036).
Elytra. Moderately depressed along suture, comparatively short (LE/SBL 0.54±0.014) and narrow (WE/LE 0.67±0.022), without traces of striae. Humeri distinct, rounded, in outline forming obtuse angle with longitudinal axis of body. Lateral margins subparallel, slightly divergent at basal half, evenly rounded to apex in apical half.
Male genitalia. Median lobe (Fig. 7 G–J) with long shaft, almost straight ventral margin and elongate apex with rounded tip. Sclerites of internal sac remote from each other, the dorsal sclerite bifurcated apically, markedly longer than ventral sclerite. Left paramere with short and conical apical constriction (Fig. 7 H, K). Ring sclerite with moderately long, almost symmetrical handle, narrowly rounded at tip (Fig. 8 D).
Female internal genitalia. Gonocoxite 2 with prominent basal ridge and ensiform setae of moderate length (Fig. 9 B, E). Spermatheca weakly sclerotized, elongate, of barrel shape (Fig. 10 B). Length of spermathecal gland much greater than length of spermatheca. Spermathecal duct slightly wavy and very long.
Geographical distribution. This species is broadly distributed within the subgenus range, inhabiting the mainland of the eastern part of the Northland and entire Auckland regions, with adjacent islands off the East coast (Fig. 11, blue quadrangles).
Way of life. This species has been collected in wide range of habitats, including forest litter, decaying and rotten wood, also from the litter in shearwater colony.
Relationships. Males of this new species resemble males of P. constricticollis, described above, based on the rounded tip of the median lobe, but differ in other details of aedeagal structure.
