Diagnosis
A pale-yellow species ( Fig. 57A View Fig ), including the mediotergite, and with only slightly elongated head and eyes; in contrast to similar species, it has a small, pale epandrium. The pair of long frontal setae in front of the ocellar triangle are set close to the anterior ocellus; 2 short posterior fronto-orbital setae. The most easily appreciated character of this species is in the shape of the surstylus, which is broad at its base and curved with a setula at its apex. Similar species: A. nudum Ebejer, 2007 from Mongolia and A. curvistylus sp. nov. from Israel are similar in external characters, but all three species differ in details of the hypopygium (see above under A. curvistylus ).
Etymology
The species is named in honour of N. Meltser, who collected a significant amount of specimens of Aphaniosoma from Israel during the Tamarisk trees survey. (His name on the data labels is spelled with a “z”.)

Male (holotype)
HEAD. Yellow including ocellar triangle and entire occiput; frons longer than broad, narrowed anteriorly, at level of antennae about 0.5 × as wide as at level of anterior ocellus; gena narrow in front, deeper behind, in profile, below middle of eye, about 0.4 × as high as eye, with numerous white setulae; occiput in profile narrowly visible behind eye, with short, pale postocular setulae in one row; 1 vibrissal seta well differentiated from buccal row of setulae; face short and narrow, depressed and poorly sclerotized; median carina low and short; antenna yellow, pedicel with short seta dorsally; basal flagellomere with fine pubescence along anterior margin shorter than diameter of basal segment of arista; basal ⅓ of arista pale, with fine pubescence; chaetotaxy: 2 posterior fronto-orbitals with 3 very short setulae anterior to them; ocellars a little longer than posterior fronto-orbital, paraverticals short and convergent; 1 medial vertical and 1 lateral vertical; frons with longer pair of setae in front of anterior ocellus and about 8 short pale setulae scattered across frons.
THORAX. Yellow, covered with pale yellow microtomentum, especially on scutum; chaetotaxy: 1 postpronotal, 1 intra-postpronotal, 1 presutural, 2 notopleurals, 0+4 intra-alars, 1 postalar, 3+6 dorsocentrals, only prescutellars strong, 1+2 acrostichals with prescutellars not developed, 4 scutellars, 1 anepisternal, 1 katepisternal at upper posterior corner and with a vertical row of 3 fine setulae at middle.

ABDOMEN. Tergites yellow and sparsely setulose basally; setulae longer on margins of tergites 4–6; sternite 6 ( Fig. 59B View Fig ), in ventral view, of triangular shape with long extension anteriorly, seen shining in the midline of lower half of the hypopygium in Fig. 58A. View Fig
HYPOPYGIUM ( Figs 58 View Fig , 59A View Fig ). epandrium small, pale; surstylus, short, broad at base, curved almost through 90°, and setulose at tip; cercus very pale and long setulose; pregonite rounded at apex, with a row of short setulae, and setulose at apex; postgonite short, barely reaching beyond edge of epandrium, translucent and not easily seen; aedeagus all yellow and not properly characterized.
