03F4744DFFAEFF86199BB937FB6AFB5A.taxon	description	Chaetotaxy on the mesoscutum is stable and is as follows: The acrostichals are generally uniseriate in Teuchophorus and rarely absent. In the T. pauper group the acr are always absent. Some species of the T. gratiosus group also lack acrostichals. Four to five dorsocentrals; one humeral with a hair beside, two notopleurals, one posthumeral, one presutural, one sutural, one intraalar, two supraalars; scutellum with two strong marginals. The first tarsomere of the hind leg is always shortened. Vein m 1 + 2 is turned up immediately after the connection with the cross vein tp and not presenting a wing “ boss ” at some distance of the cross vein like in the Sympycnus – Chaetogonopteron- complex. Males have often a stigma, being a darkened swelling on the costa. It is present in most Palaearctic species, but in Singapore only T. stenostigma has a slight thickening and darkening of the costa. The other species do not display that character.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

03F4744DFFACFF8219EEB8F7FD6EFE1A.taxon	etymology	Etymology. – The species name temasek refers to the name of ancient Singapore, which means “ city at the sea ”. Used as a noun in apposition.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore. Raffles Bulletin of Zoology 54 (1): 59-82, DOI: 10.5281/zenodo.13245314
03F4744DFFACFF8219EEB8F7FD6EFE1A.taxon	discussion	Discussion. – Teuchophorus temasek, new species, is closely related to T. gratiosus but the latter has uniseriate acrostichal bristles and the arista very short. In T. temasek, the arista is longer than the third antennal segment and there are no acrostichal bristles. A synapomorphy are the long marginal bristles on the first tergite. Teuchophorus temasek, new species, and T. neesoonensis, new species, are sister species. The main differences in the two species are the length of the third antennal segment and the arista. In T. temasek the third antennal segment is nearly 3.5 times as long as wide with the arista longer than the third segment (about 1.5 times as long) and the basal antennal segments are yellowish. In T. neesoonensis the third antennal segment is 4.5 times as long as wide and the arista is shorter than the third segment (3 / 4 length of third segment). The basal antennal segments are brown. The structure of the hypopygium of both species is almost identical. Both have two strong lateral epandrial bristles on a tubercle and a small median epandrial seta. A strong dorsal bristle is present on the dorsal surstylus. The cercus bears a very long apical bristle. Finally, T. temasek and neesoonensis differ from T. antennatus new species in having no acrostichal bristles and the presence of a well-developed arista. T. antennatus has a very short spine-like arista and distinct, uniseriate acrostichals. It also lacks the very long apical bristles on the cercus and has only a single lateral epandrial bristle.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

03F4744DFFA9FF8019EBBB9BFAA5FB9A.taxon	discussion	Discussion. – The new species is closely related to T. trangensis Bickel, 1999. Both have a very long third antennal segment with a very short arista and the base of the third antennal segment has a peculiar subrectagular broadening. In T. trangensis the arista is somewhat longer than the width of the third antennal segment, whereas in the new species the arista is shorter: about half as long as the width of the third segment. In T. trangensis both basal antennal segments are yellow, while only the scape is yellow in the new species. The male genitalia of T. trangensis are not illustrated, but Bickel states (l. c.) that the genitalia of T. trangensis are similar to those of T. gratiosus. The latter has a very long aedeagus, and two long, lateral epandrial setae on a tubercle. The new species has a short aedeagus with a sagged tip and only one lateral epandrial seta. Although T. trangensis and the new species are morphologically very similar, we consider the morphological characters as sound enough to distinguish them as separate species. For a further comparison with T. temasek and T. neesoonensis, I refer to the key and the descriptions above.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

03F4744DFFA8FF8E19CFBEF7FBA4FC1A.taxon	discussion	Discussion. – There are three very closely related species in the T. pauper group that should be compared: T. pauper Meuffels & Grootaert, 2003, T. singaporensis, new species, and T. meieri, new species. All three species lack acrostichals, are of the same size, have yellowish brown antenna, no peculiar bristling on legs and wing without stigma. Although all three species are small in size, and even if there is variation in colouration of the thorax and the bristles, they can easily be recognized in lateral view, by looking at the shape of the hypandrium and the surstyli. T. singaporensis, new species, and T. pauper are very closely related. Both have 5 equally long dorsocentrals that are yellowish-brown, prosterna entirely brown with a central black stripe and mesopleura almost entirely brown. The most obvious difference is in the genitalia. Both, T. singaporensis and T. pauper have an asymmetrical hypandrium while T. meieri has a symmetrical hypandrium. It is not possible to differentiate T. pauper from T. singaporensis on the somatic characters, but the structure of the male hypopygium is very different: shape of the surstyli, hypandrium, dorsal epandrial lobes and aedeagus. T. meieri, new species, has 4 equally long, black dc, yellow prosterna with a small central black spot and only the upper third of the mesopleura brown, lower two thirds are yellow. T. meieri has, seen in apical view, a large hypandrium with long, symmetrical arms. Both arms end in a large, bifid tip. The ventral epandrial extensions are also symmetrical and the tip, in lateral view, is very wide. The surstyli are rather short in comparison to the long, digitiform surstyli in T. pauper and T. singaporensis.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

Specimens of the type locality (Sa Nangmanora near Phang-Na, Thailand) were re-examined. In the original description (Fig. 120) the structure of the right hypandrial arm was misinterpreted. It is much shorter and has a rugose (wrinkled) tip. The dorsal epandrial lobe is very long and bears two short, pointed appendages (Fig. 20). I have not found T. pauper in Singapore. Considering its distribution in South-Thailand and the mixed populations of T. pauper and T. singaporensis, it is likely to occur in Singapore as well.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

We refer to the discussion under T. singaporensis to distinguish T. meieri from T. singaporensis and T. pauper. There are more species without acr especially in the T. gratiosus group. Here in Singapore, there are T. temasek, new species, and T. neesoonensis, new species. The males of both have very long antennae. The females having short antenna, that are however at least as long as wide, are hard to distinguish from T. pauper and T. meieri. T. spinulosus, new species, and T. acuminatus, new species, also lack acrostichals, but have the third antennal segment about 1.5 times as long as wide.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

03F4744DFFA2FF891A9EBBEBFF1AFC5A.taxon	etymology	Etymology. – The name acuminatus refers to the pointed tip of the third antennal segment (acuminatus Lat. for pointed).	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore. Raffles Bulletin of Zoology 54 (1): 59-82, DOI: 10.5281/zenodo.13245314
03F4744DFFA2FF891A9EBBEBFF1AFC5A.taxon	discussion	Discussion. – The shape of the tip of the third antennal segment suggests that T. acuminatus, new species, might belong to the T. gratiosus group. In contrast to the T. gratiosus group, the genitalia are large and there are no long marginal bristles on the first tergite. Because of the absence of the acrostichals, the rather pale mesoscutum and the asymmetrical hypandrium, T. acuminatus, new species, is provisionally placed in the T. pauper group.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

03F4744DFFA0FF9719E8BA34FA14FA7A.taxon	discussion	Discussion. – The new species looks superficially like T. simplicissimus that is sympatric. It is easily distinguished from the latter by the strong, black, curved aedeagal complex, the absence of the posterior erect hairs on the hind tibia and the absence of a basal spinule at the base of the first tarsomere of the fore leg. To identify the species quickly, squeeze the abdomen so that the large black aedeagal complex is freed or, look for absence of the erect posterior hairs on the hind tibia to separate the species from T. simplicissimus.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.

03F4744DFFBBFF921906B8F7FBC1FD9A.taxon	discussion	Discussion. – Teuchophorus stenostigma is the only Singaporean species with a slightly developed stigma, the other species have at most the costa a little darkened. T. laosensis Olejnicek, 2003, is a similar species, but it has brownish black antennae and yellow halters. The hind tibia should bear ventral bristles, but Oleijnicek’s drawing shows a row of long dorsal bristles. Teuchophorus stenostigma from Singapore has brown antennae, darkened halters, hind tibiae without ventral bristles, at most some hairs ventrally and only 3 dorsal bristles. Teuchophorus stenostigma was originally described from South Thailand (Trang province) in a similar habitat as here in Singapore. The original description mentions yellow antenna, yellow halters and largely yellow pleurae. The specimens from Singapore are all darker. The shape of the surstyli is the same, but the bristling on the ventral surstylus is longer in the Singaporean specimens. At the moment we consider them conspecific.	en	Grootaert, Patrick (2006): The Genus Teuchophorus (Diptera: Dolichopodidae) In Singapore.
