Berzercon ferdinandi Seeman & Baker 2013

Berzercon ferdinandi Seeman & Baker 2013: 132 .

Type depository. Landcare Research , Auckland, New Zealand .

Material examined. Two female and two male paratypes ( OSAL 104613–104614 , 114590 , 114748 )

Remarks: All specimens were recovered from Carabidae , Megadromus sp. , Mecodema sp. , and Plocamostethus sp. from New Zealand ( Seeman & Baker 2013).

The grouping of all remaining Heterozerconoidea , that is Discozerconidae s. s. plus Heterozerconidae , is characterized by the following character states: inside movable digit female with brush-like structure (4); cornicula membranous (23); setae Zv 3 in adults absent (62, reversed in Amyzozercon ); tibiae I setae ad3, pd3 ((88), tibiae II–IV setae ad2, pd3, pl2 (95–97), genua I setae ad3, pd3 (86), genua IV seta ad3 (99), femora II seta pv2 (91), and femora III seta v3 all absent (98). Although the number of characters listed is impressive, it is worthwhile noting that nearly all of them concern leg chaetotaxy, which is quite similar in Berzercon and Sejidae . Use of alternative outgroups renders most of these characters as apomorphies of Berzercon , reducing support for the lineage of Discozerconidae s. s. plus Heterozerconidae .
