Chrysso hejunhuai Barrion, Barrion-Dupo & Heong , new species [ Figure 39 A-H]

MALE. Holotype male, total length 2.34 mm. Cephalothorax length 0.94 mm, width 0.88 mm. Abdomen width 2.00 mm, width 1.09 mm.

Carapace. Orange red except black eye area and rough interrupted brown concave lines posterior of the eye area, slightly longer than wide. Chelicerae yellow, longer than wide (0.52: 0.23 mm). Promargin toothless and retromargin has two teeth. Maxillae yellow, almost 2x longer than wide, apicoinner tip pointed and converging. Labium yellow and pointed apically. Sternum yellow, slightly longer than wide (0.74: 0.69 mm), truncate opposite coxa I and posterior end between coxa IV.

Eyes. In two rows, AER slightly longer than PER (0.31: 0.36 mm). Eye diameter (mm):AME (0.09)> PLE (0.07)> PME (0.06)> ALE (0.05). Eye separation (mm): AME-AME = PME-PLE (0.9)> PME-PME (0.06)> AME-ALE (0.05). Median ocular quad wider in front than behind (0.20: 0.17 mm), height 1.17x longer than anterior width. Clypeus height very wide, 3.4x AME diameter.

Legs. Long and slender with many short brown hairs, brown except orange basal half of femur I-IV. Leg formula 1423.

Abdomen. Yellow orange with a pair of midlateral black spots and a transverse black band towards posterior end, 1.83x longer than wide. Anterior tip strongly pointed. Posterior black spot lined with three pairs of brownish black hairs. Venter dull yellow except a brown anterior plate.

Palpal organ has tegular apophysis strongly concave on anterior margins, subtegulum relatively elongate transversely, wider than high. Cymbium with a deep cut before tip, apex tooth-like and pointed in lateral view. Femur dorsally lined with 6-7 dorsal bristles.

FEMALE. Unknown.

Material Examined. Holotype male (coll. no. H72), CHINA, Hainan Island, Haiko, 21 April 2012, ATBarrion, JLACatindig and SCVillareal. Two paratype males (coll. no. H78 & H79), exactly same data as for holotype.

Diagnostic Features. This species closely resembles C. trimaculata Zhu, Zhang and Xu, 1991 but differs from the latter in (1) very pointed anterior tip of abdomen, (2) body and leg measurements, (3) structure of the palpal organ.

Etymology. Patronym, in honor of Dr. He Junhua for his monumental works on the Hymenoptera systematics of Braconidae , Dryinidae and Ichneumonidae of China—key biological control agents in the agricultural landscape.
