( Figs. 10 , 12B )

Ngirhaphium murphyi Evenhuis & Grootaert, 2002: 310 . Type locality: SINGAPORE: Kranji mangrove.

N. murphyi Grootaert & Puniamoorthy, 2014: 147 (figs. 1–3, 4, 5, 18).

Diagnosis. A medium to large species (5.7–7.3 mm), generally with clear wings. Mesonotum and tergites metallic green. Apical aristal segment quite thick and short, only half as long as basal aristal segment. Male with cerci longer than surstyli and thus the tips are visible outside the surstyli.

Material examined. THAILAND: 1 ♂, 4 ♀, Satun province, Tarutao Island, Talo Wao bay (6°36′58.7″N 99°40′43.1″E), 11.viii.2014 (collected A. Samoh) ( PSUNHM) .

Krabi province: 1 male, 3 females, Ko Lanta, Ko Lanta Yai (7°38′40.9″N 99°02′42.3″E), Samoh A, sweep netting, 1 April 2018 ; Phang Nga province: 5 males, 1 female, Khuraburi, Phra Thong Island (9°03′04.8″N 98°15′56.8″E), Samoh A, sweep netting, 23 April 2018 ( PSUNHM) ; 1 male, Takua Thung, Kalai, Ban Khuan Kalai (8°19′12.8″N 98°25′46.2″E); Samoh A, sweep netting, 14 July 2018 ( PSUNHM) ; 1 male, Thappud, Ban Khuan Bosane pier (8°26′43.8″N 98°35′40.6″E); Samoh A, sweep netting, 15 July 2018 ( PSUNHM) .

Singapore: 37 specimens recorded from Mandai, Sungei Buloh and Pulau Ubin (35 barcoded; LKCNHM).

Remarks. The pedicel is yellowish-brown in females and black in males in southern Thailand. The pedicel is always black in both sexes in Singapore populations ( Grootaert & Puniamoorthy, 2014).

Distribution. Singapore and South Thailand, Andaman Sea.
