urn:lsid:zoobank.org:act:C13CCE8B-1279-4FF8-8464-30553592E4B3

Type species

Gergithus (Maculergithus) tamdao subgen. et sp. nov.

Diagnosis

The new subgenus Maculergithus subgen. nov. in Gergithus is here erected for the species sharing the combination of the following characters:

(1) ground colour black-brown;

(2) tegmina with numerous yellow spots separated from one another;

(3) frons with a broad yellow transverse band above fronto-clypeal suture;

(4) mesonotum with yellow spot on each lateral angle;

(5) posterior margin of pygofer of male genitalia strongly rounded posterad in lateral view;

(6) anal tube elongate, truncate apically and with apicolateral angles projecting posteroventrally.

Etymology

The name is formed by the combination of “ maculatus ” (adj., Latin) = spotted and “ Gergithus ”, the genus to which pertains the new subgenus. It is masculine in gender.

Species included

Gergithus (Maculergithus) luteomaculatus subgen. et sp. nov. ( Vietnam, Tam Dao National Park), Gergithus (Maculergithus) multipunctatus Che, Zhang & Wang, 2007 ( China, Hainan Island: Jianfeng Mountain),

Gergithus (Maculergithus) nonomaculatus Meng & Wang, 2012 ( China, Hainan Island: Bawangling Mountain),

Gergithus (Maculergithus) tamdao subgen. et sp. nov. ( Vietnam, Tam Dao National Park).

The subgenus currently contains 4 species, but an undescribed species from Hainan Island (Wuzhishan), illustrated and erroneously referred to as G. multipunctatus in both Chen et al. (2014: 56) and Guo & Chen (2015), also belongs to the group.

Pending additional new groupings (see discussion), all other species are currently retained in the nominal subgenus Gergithus (Gergithus) Stål, 1870 .

Distribution

Currently known distribution includes Hainan Island ( China) and Tam Dao massif (North Vietnam) ( Fig. 1 ).

Biology

All species seem to live in forested zones of mountainous regions.
