Re: Insect or Invertebrates Identification

Some investigation about these ones:
1. bottom left is a tachninid and I have no clue for further ID
2. top right is most likely a Lispe sp., Muscidae and a view of the abdomen would be great and some more detail on the legs and antennae (colouration is apparently important)

Lispe is represented by 50 species in the Afrotropical Region, 15 of which have been recorded from South Africa:
Lispe hirtibasis, L. irvingi, L. spinipes
L. andrewi, L. barbipes, L. biseta, L. capensis, L. cilitarsis, L. flavipes, L. kowarzi, L. nana, L. surda, L. tuberculitarsis, L. zumpti
L. tentaculata
Diagnosis Genus Lispe (Subfamily Coenosiinae. Tribe Limnophorini)
Lispe Latreille, 1796 is a muscid genus of median body size with worldwide distribution and diversity estimated of about 200 species by Vikhrev (2014).
This genus is recognized mainly by the following characters:
Both in larval and adult stages, Lispe flies are commonly found near waterbodies (from salty to fresh), acting as aggressive predators of small insects and other soft-bodied invertebrates.
frons broad in both sexes
Proboscis not adapted for piercing: sclerotised and retracted into head, with labella well developed and fleshy
Palpus greatly enlarged in apical part, spoon-like
Antenna inserted below mid level of eye;
presutural dorsocentral setae well developed
katepisternal setae 1:1 or 1:2.
parafacial with setulae
upper orbital setae 2
Anepimeron setulose
Lower calypter: inner margin diverging immediately and at right-angles from supra-squamal ridge; tongue-like in shape
all wing veins bare

Two new species of the leucospila group are here described. The new species can be separated from L. leueospila (Wied.) and L. irvingi
Curro (= L. afra Curr., n. syn.), the previously described Ethiopian species with mainly yellow tibiae
From the SANBI-list these ones from SA in this group: L. irvingi, L. andrewi,
Lispe andrewi n. sp.

reaching ptilinal suture. Antennae dark except for distal rim of orange
on the second segment; arista slender with long hairs above and below.
Palpi yellow; proboscis glossy black. Occiput grey, with a black streak
from neck to vertex; vertex brownish dusted. Parafrontalia with three
strong and two weak inclinate setae, and two rec1inate orbitals which are
bent outwards, the anterior one weaker; a pair of strong, divergent
proclinate ocellars and strong inner and outer verticals present.
Mesonotum grey in ground colour and with a median brown vitta
which is a little wider than the distance between the prse acrst, and which

fine pair through the de rows and a pair of quite broad, diffuse brown
vittae running back from the humeral calli. Remainder of the thorax bright
'grey, except for a tinge of brown on the mesopleuron. dc, 1 + (2) 2, the
prst de is situated at 0.7 of the distance from the anterior margin of the
thorax to the suture. Tibiae more or less extensively infuscate and dusted

black except for two lateral spots. No lateral black stripe is present on
the first two tergites. Male genitalia; Cerci much broader and less slender
than in irvingi; third sternal plate very slender; phallosome bears its spine

Holotype: rJ, leg. Miss A. Andrew, Entabeni, Zoutpansberg, Northern Transvaal, September, 1952.
This species resembles Lispe irvingi Curran very closely but may be
distinguished by its distinctly darker tibiae, the side of tergite 3 being black,
and the very distinct cerci and third sternal plate in the male genitalia.

being the strongest; there are two pd preapicals. t~ with a pv postmedian
seta. f8 with an ad row of strong setae and a median av seta. t3 with
median ad and pd setae and a postmedian avo
Abdomen slender and oval in shape; dorsum shining black with 3
lateral white emarginations on the segmental lines, these white areas run
into the grey of the venter. The black on tergite three extends further
ventrally than on the other segments. Prominent lateral setae present on
the first three tergites (the first two segments carry several smaller dorsals
and laterals); the fourth tergite bears an apical row of six setae.

Variation observed in other material; Transverse bands of wings vary
in strength and may be absent. Mesonotum usually as in the holotype but
may be much less yellow; it is occasionally lightly greyish dusted.
Female: Very similar to the male but with much less long hairs on
the lower sternopleuron, fore and mid coxae. Wings lack the transverse
band of the male. Abdomen less slender and the dorsum less intensely
black; a median vitta is present on at least the second and third segments
and at times on all four. The grey of the sides and venter of the abdomen
15 at times tinged with brown.
Length: 4.5-5.0 mm.

1= male L. barbipes
The Lispe longicollis species-group was proposed by Hennig (1960) based on the characteristic shape of a vein M which is distinctly curved forward at apex. The species of this group also share these additional characters: t3 with submedian av, ad and pd setae; abdomen with large, more or less fused trapezoid spots; frontal triangle narrow; dc 2+4, usually only 2 posterior pairs are strong
