Hemiandrus

Abstract

Key to Fiordland Hemiandrus Most adults and late-instar nymphs are readily identifiable by color pattern, and Figure 6 provides a basis for this method. The following key makes use of specific structural and color characters: 1. Dorsal metatibial spines very slender, well separated, equal- or shorter than protibial and mesotibial spines........................................................................................................................................................... 2 - Dorsal metatibial spines stout, connected by basal webbing, and distinctly larger than protibial and mesotibial spines......................................................................................................... "Esperance Valley" 2. Maxillary palp: 3 rd segment glabous or setose, but not pilose................................................................... 3 - Maxillary palp: 3 rd segment pilose across distal 20–40 %......................................................................... 6 3. Frons smooth or microsculptured; adults not exceeding 33mm; ventral surfaces of tarsi white or cream 4 - Frons rugose; adults 35–45mm; ventral surfaces of tarsi grey.............................................. superba n. sp. 4. 4 th protarsal segment densely setose on distal 5 %, cream above; ventral spines on metatibiae absent or minute, in linear series of 4, cream or dark brown; pronotum brown and/or black................................... 5 - 4 th protarsal segment densely setose on distal 20 %, dark brown above; ventral spines on metatibiae prominent, in a linear series of 3, white; pronotum red with some black.................................. nitaweta n. sp. 5. Ventral spines on metatibiae (if present) in linear series of 4; pronotum predominantly black; maxillary palp: 4 th segment pilose on distal 55–60 %......................................................................................... focalis - Ventral spines on metatibiae in linear series of 5; pronotum predominantly brown; maxillary palp: 4 th segment pilose on distal 40 %........................................................................................ "HunterMountains" 6. 4 th metatarsal segment densely setose across entire dorsal surface; metafemorae usually with distinctive grey or light brown spots............................................................................................................................ 7 - 4 th metatarsal segment densely setose only on distal 20 % of dorsal surface; metafemorae lack spots............................................................................................................................................................... fiordensis 7. Adults 20mm; midline of pronotum uniform or speckled; frons black; female: posterior margin of 9 th tergite straight..................................................................................................................
