( Figs. 31-34 )

Meuffels & Grootaert, 2003: 222, Figs. 192-197.

Material examined. – SINGAPORE: 15 males, Sungei Buloh , 6 Oct.2000 (20032, coll. P. Grootaert & N. Evenhuis) ; 19 males, 22 females, Sungei Buloh , 9 Dec.2002 (22057, coll. P. Grootaert) ; 7 males, Sungei Buloh , 28 May.2005 (25037, coll. P. Grootaert, Si 555) ; 62 males, Sungei Buloh , 22 Jun.2005 (25121, coll. P. Grootaert, Si 795) ; 10 males, Sungei Buloh , 26 Aug.2005, sweep netting (25321, coll. P. Grootaert, Si 1020) ; 1 male, Kranji , 27 Jul.2005 (25254, coll. P. Grootaert, Si 926) .

MALAYSIA: 70 males, 48 females, Pulau Tioman , Monkey Bay, 14 Jul.2005 (25217, coll. P. Grootaert, Tio 30) ; 14 males, Juara , 20 Jul.2005 (25244, coll. P. Grootaert, Tio 76) ; 67 males, Juara , 20 Jul.2005 (25245, coll. P. Grootaert, Tio 86) ; 33 males, Juara , 20 Jul.2005 (25246, coll. P. Grootaert, Tio 124) .

Diagnosis. – Third antennal segment hardly as long as wide. Costa not swollen, but darkened between r1 and r2+3. First tarsomere of fore leg with a basal spinule. Mid femur without bristles. Mid tibia with a row of ventral spinules in apical third. Hind femur without ventrals. Hind tibia posteriorly in second basal quarter with about 5 erect hairs. Tip of hypandrium with a small hook.

Discussion. – The specimens in Sungei Buloh are a little smaller than the ones on Pulau Tioman. Study of the male genitalia ( Figs. 33 vs. 32) suggests that they are conspecific. It is confirmed by genetic work (Wei Song, Grootaert & Meier, in litt.). For identification one should check the presence of the 5 erect hairs in the second basal quarter posteriorly on the hind tibia.

Distribution and habitat. – Thailand, Malaysia and Singapore. It is very common in the upper, less saline parts of mangroves in Singapore. The specimens in Thailand were collected on the sides of pools in a cave system in connection with a mangrove.
