Figs. 1–4 View FIGURES 1 – 4 , 9 View FIGURES 9 – 10 .

Type-species: Euconops rufus CAMRAS, 1955 by monotypy.

Material examined: 1%, Mozambique, Ponta da Barra near Inhambane, 14. – 18.XI.1997, leg. J. Bosák, coll. Stuke; 1Ψ, Mozambique, Manicata pr, 70km SE Chimoio, 23. – 24.XII.2003, leg. Halada, coll. Barták.

Diagnosis: The monotypic genus can be recognized easily because it includes the only reddish-brown species (fig. 1) with an elongated postpedicellus (fig. 3) outside of the Australis with the exception of Euconops . The differences between Euconops and Tammo / Pleurocerinella are described by CAMRAS (2000) who put at that time Tammo rufus in the genus Pleurocerinella :

“This genus [ Euconops ] is markedly different from Pleurocerinella , although the antenna is very similar. The glistening colours and bulging vertex and scutellum are very distinctive. The ocellar tubercle is vestigial and present, but may appear to be absent. This species [ Euconops bellus ] is short and robust compared to the long and slender species of Pleurocerinella .”

The main characters to distinguish Tammo from Pleurocerinella and Jelte are given in table 1.

Kö BER (1939 a) presents the most recent world key of conopid genera. Tammo belongs to Kröber's Microconops -genera group (Conopinae). At couplet 5 within this group the species doesn't fit either "Rüssel fleischig, kopflang" nor "Rüssel chitinös, 1 1 / 2 mal kopflang".

Description: Orange-brown species with black legs (fig. 1).

Head: Three distinct ocelli. The vertex cannot be recognized as a separate sclerite. Only a small area behind the ocelli has short black hairs. Antenna as shown in fig. 3: Pedicellus as long as the scapus, stylus three segmented. Proboscis approximately as long as the head (fig. 2). Labellum slightly broader than the labrum with inconspicuous and short hairs (fig. 2). Palpus short. Occiput and frons orange-brown. Parafacial with black dorsal spot (fig. 2), and with few very short, light yellow hairs. Parafacial close to the antennal grooves broadly shiny and contrasting with the adjacent dusted parts (fig. 2). Facial carina occupying about half of the length of the antennal groove, in the ventral part it joins the antennal groove. Gena broad (fig. 2). Head without setae.

Thorax: Mesoscutum with submedial and sublateral dusted vitta, with few short black hairs, primarily arranged in submedial row. One small anterior and one larger posterior notopleural seta, 4 – 5 setae at the katepisternum and 1 – 2 setae at the propleuron which are quite small. Wing hyaline, completely covered with microtrichia (fig. 4). Alula about 2 – 3 times as broad as basal medial cell [bm], completely covered with microtrichia. Vena spuria in radial cell r4+5 distinct. Angle between discal medial-cubital crossvein (DM-Cu) and apical media (M) is about 125°. Radial-medial crossvein (R-M) beyond middle of the discalmedial cell (dm) and beyond the junction of the subcostal and costal vein. Legs predominantly with scattered short black hairs, coxae without hairs. Middle femur posterodorsally with a row of 8 – 11 regular arranged black hairs. Femora without any bristles. Basitarsi ventrally with dense black hairs. Tibiae completely dusted.

Abdomen: Male abdomen as fig. 1, tip of female abdomen as fig. 9. Tergites 5 and 6 each with a pair of silver dusted spots (fig. 1).

Etymology: The genus name, Tammo , is dedicated to my older son. The name is to be treated as male.

Distribution: The only published records of this species have been the female holotype from Kenya and one additional specimen from Mozambique ( CAMRAS 1962 as " Euconops bellus ", see CAMRAS 2000). The known distribution is restricted to Kenya and Mozambique.
