Type material. Hඈඅඈඍඒඉൾ: J, point-mounted ( NZAC): ‘ NEW ZEA- LAND WO Mahoenui Gribbens Road 26 Jun 1977 G.W.Ramsay // Litter 77/81’. Pൺ*©ൺඍඒඉൾ: 1 ♀, same label data as holotype.
Description. Body ( Fig. 8A View Fig ) length 1.90 mm, about 2.19× as long as wide (BL/AW = 2.19). Head about 1.29× longer than wide (HL/HW = 1.29). Eyes with 15 facets. Pronotum about as long as wide (PL/PW = 0.97). Elytra wider than long, about 0.58× as long as wide (EL/EW = 0.58) and about 0.76× as long as pronotum (EL/PL = 0.76). Abdomen about 1.21× longer than wide (AL/AW = 0.94).
Male. Eyes with 15 facets.Abdominal concavities ( Fig. 8B View Fig ) present on V1, V2, V3 and V4, and all inner surfaces polished; C1 and C2 well-impressed with distinct edges, C2 deep and lacking spines, greatest width longer than length of metatrochanter and slightly widened posteriorly; C3 broader than C2 and lacking spines, C4 very weak. Metatrochanter ( Fig. 8C View Fig ) with inner face concave with well-developed longitudinal carina; metafemora weakly curved at apex; metatibia ( Fig. 8D View Fig ) with small apical spine. Tergite 5 about 1.5× wider than long, broadly rounded.
Female. Eyes with 14 facets.
Differential diagnosis. This species can be easily distinguished from its congeners by males having a well-developed concavity on V1 and metatrochanter with inner face concave with a well-developed longitudinal carina. It is most like P. graceae sp. nov. by C3 lacking apical spines but can be separated from it by the metatrochanteral process having the concave inner face and V1 lacking a concavity. Additional male characters that characterize this species are as follows: C2 deep and polished with edge conspicuously demarcated with side rims and without apical spines and metatibia without small apical spine.
Etymology. This species is dedicated to Graham Ramsay, entomologist, and collector of the new species; it is a noun in genitive singular.
Distribution. North Island: WO.
