Park, J. - S. & Carlton, C. E., 2014, A revision of the New Zealand species of the genus Sagola Sharp (Coleoptera: Staphylinidae: Pselaphinae: Faronitae), The Coleopterists Bulletin (mo 13) 68, pp. 1-156 : 38

5. pulchra species-group

(4 species)

Diagnosis. The members of the pulchra species-group can be distinguished from other Sagola species-groups by the following combination of characters: large body length 3.2–4.2 mm; antennomere 1 approximately 2.5 times longer than wide with dull surface; gular region of male head with transverse depression ( Fig. 19j ); ventral surface of male head with a pair of processes laterally ( Fig. 19j : arrow); hind wings reduced to small pads; fore and mid-femur with semicircular depression ( Fig. 19k ); male mid-femur at least twice as broad as tibia ( Fig. 19k ); Male tergite IV without microtrichial patch; abdominal tergites IV–VI with discal carinae; female abdominal ventrite VIII triangularly produced posteriorly ( Fig. 19l ), ventrite IX deeply emarginate posteriorly ( Fig. 19m ); present on North Island, not known from South Island ( Fig. 20 ).

KEY TO SPECIES OF THE PULCHRA SPECIES- GROUP

The key is based on genitalia because most specimens are indistinguishable based on external morphology.

1. Median lobe of genitalia without minor lobe; broader paramere without branch from base ( Fig. 19e )...... S. pulchra Broun

1′. Median lobe of genitalia with minor lobe; broader paramere with 1 or 2 branches from base .................................................2

2(1′). Branches of apical lobe of genitalia approximately equal............................................... 3

2′. Apical lobe of genitalia with longer major branch and shorter minor branch ( Fig. 19h ) .......................... S. poortmani new species

3(2). Apical lobe of genitalia with U-shaped emargination; right paramere with 2 branches from base ( Fig. 19f ) .................. ......................... S. keejeongi new species

3′. Apical lobe of genitalia with V-shaped emargination; left paramere with 1 branch from base ( Fig. 19g ) ................................. ............................ S. ramsayi new species
