TYPE MATERIAL. Holotype – ♂, China: Yunnan Prov., Xishuangbanna , 1.V 2015,

Zhu Xiaoyu ( ECNU). Paratypes: 2 ♀ , same data as for holotype ( ECNU) .

DESCRIPTION. MALE (holotype). Colouration and structure of body similar to those of

A. excultus but with following characteristic features: head, thoracic tergites, tegmina and abdomen mostly black, approximately as in some paratypes of A. excultus ; legs light brown with orange tinge and black most part of hind femora (whitish or light greyish area in middle and inner proximal parts of hind femora absent, but this inner part less darkened, and apical part of these femora as other legs in colour; Fig. 1 ); tegmina very similar to those of A. excultus but reaching middle part of 5th abdominal tergite, with 7 longitudinal veins in dorsal and 6

such veins in lateral fields ( Fig. 1 ); genitalia with anterior epiphallic lobe (curved upwardsbackwards) having lateral parts rather narrow (short), with dorsal projection of posterior epiphallic lobes wider than in A. excultus ( Figs 18 , 30 ), with ventral projection of these lobes very short (much shorter than in A. excultus ) and having almost rectangular notch between it and dorsal projection in profile ( Figs 20 , 32 ); mesal lobes larger, completely separated from ectoparameres and with almost truncate anterior apex ( Figs 19 , 31 ); endoparameres with median angular structure somewhat longer than in A. excultus (reaching anterior edge of epiphallus) and having small median apodeme ( Figs 18, 20 , 30, 32 ); rami rather strongly widened in posterior third and with short medial projections directed backwards ( Figs 18–20 ,

30–32 ).

FEMALE. General appearance as in male, but tegmina reaching middle part of 4th abdominal tergite. Abdominal apex almost indistinguishable from that of female of A. excultus ,

but ovipositor practically equal to hind femur in length ( Fig. 2 ).

MEASUREMENTS (length in mm). Body: ♂ 13, ♀ 15; pronotum: ♂ 4, ♀ 4; tegmina: ♂

4.5, ♀ 4.5–5; hind femora: ♂ 10, ♀ 10–11; hind tibiae: ♂ 7, ♀ 8; ovipositor 10–11.

ETYMOLOGY. Species name magnigenitalis reflects the presence of expanded posterior epiphallic lobes in male.
