Name
Megacanthaspis hainanensis Wei & Feng sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Material examined
Holotype: adult female: CHINA, Hainan Prov., Gaotuo mountain, 19.5.1963, Chou (NWAFU).
Paratypes: 12 adult females, same data as the holotype (NWAFU).
Description
N=13. Adult female. Appearance in life was not recorded. Slide-mounted adult female 513–597 μm long (holotype 577 μm long); 199–209 μm wide (holotype 209 μm wide), body outline fusiform, with obscure segmentation. Cephalothorax. Antennae each with a long seta and a tubercle. Anterior spiracles each with 2–4 trilocular pores; pores absent from posterior spiracles. Pygidium with serrate process (plates) on abdominal segments VI-VIII, lobes absent, plates arranged 2, 3, 3 among the marginal gland spines, without paraphyses. Marginal gland spines each 9.93–18.9 μm long, in 5 pairs on abdominal IV-VIII, more or less enlarged, each associated with 2–4 microducts, median pair widely separated. Gland tubercles present on prothrax, metathrax and abdominal segment I-II, each with 1 microducts. Dorsal macroducts present on abdominal segments I-VIII; forming more or less segmental rows on abdominal segments I-VI, but scattered on abdominal segments VII-VIII; with a macroduct between median gland spines. Ventral macroducts 2-barred, as big as dorsal macroducts, scattered occurring on lateral body margin on prothorax, metathorax and abdominal segments I-IV. Ventral microducts present on prothorax, metathorax, segments I-IV. Anal opening about 68 μm long from apex. Perivulvar pores in an arc with a total of 13–25.
Diagnosis
The new species is very similar to Megacanthaspis phoebia, but can be distinguished by by having (character-states on Megacanthaspis phoebia in brackets): (i) 5 pairs of marginal gland spines (6 pairs); (ii) a macroduct present medially between the median gland spines (absent).
Etymology
Named after Hainan, the type locality.
Distribution
China (Hainan).
