Terr. / Ukerewe I. / Father Conrad.”, “ Selinus / femineus / Lucas / Det. G.E.Bryant”; female (BMNH): “Tang.

Conrads.”, “ Quadrideres / lesnei / Koch / P. Ardoin det. 1962”.
Locus typicus. Ukerewe Island (Tanzania).
Etymology. This new species is dedicated to the memory of my grandfather Kazimierz Józef Kamiński (born on the 13th of December, 1926, in Grabina Radziwiłłowska, Poland, died on the 2nd of November, 2009, in Żyrardów, Poland).
Diagnosis. This species is similar to all of the members of the Q. simplicipes species-group (Q. simplicipes, Q. ruandanus and Q. robynsi) having the inner contours of male anterior tibiae without strongly postmedian dilatation (cf. Kamiński 2013a) and with the secondary intervals and epipleurae of elytra with coarse punctures (Fig. 7, 8). Q. kazimierzi sp. nov. can be easily distinguished from Q. simplicipes by having an unbordered 5th abdominal ventrite (Fig. 9, 10). From hitherto described representatives of the Q. simplicipes species-group, Q. kazimierzi sp. nov. differs by having strong lateral indentations and interrupted emargination of pronotal base, and pronotum widest at 0.75 of its length (Fig. 5–7).
Description. Measurements. Body—length = 9.0–11.0 mm; width ratio elytra / pronotum = 1.0–1.1; length ratio elytra / middle of pronotum = 2.1–2.2. Clypeus— clypeal emargination width / depth ratio ca. 7.0. Antennae—length ratio of antennomere 3rd / 2nd ca. 3.0. Maxillary palp—ratio width of maxillary palp / length of 3rd antennomere ca. 1.2. Pronotum—middle of pronotum length / width ratio = 0.8–0.9. Elytra—elytra length / width ratio = 1.3–1.4. Scutellum—width ratio anterior margin of elytra / scutellum at base ca. 5.5. Metaventritelength ratio cavity of hind coxa / metaventrite between the insertions of mid and hind coxae = 2.7–2.8. Abdomenwidth ratio process of 1st abdominal ventrite / process of metaventrite = 1.3–1.5. Male legs— protibiae length / width ratio = 4.1–4.4; profemur length / width ratio = 2.8–3.0.
Habitus as in Fig. 1.
Dorsal side of head dull with coarse punctures (0.5–1.0 diameters apart). Frontoclypeal suture fine. Clypeal emargination shallow. Mentum with median part narrow. Submentum with short base.
Pronotal disc dull, with coarse punctures (1.0–1.5 diameters apart). Anterior pronotal angles rounded. Lateral sides of pronotal disc subparallel (pronotum widest at 0.75 of its length). Pronotal disc with apophyseal and basal depressions (cf. Raś & Kamiński 2013). Lateral emargination of pronotum complete. Basal emargination interrupted laterally (Fig. 7). Pronotal hypomeron dull, without punctures.
Elytral rows with coarse punctures (1.0 diameters apart). Intervals dull, with coarse punctures (1.0–1.5 diameters apart). Elytral base straight. Elytral humeri rounded, slightly protruding laterad (Fig. 7). Scutellum triangular.
Intercoxal process of prosternum straight with complete bordering. Metaventrite without tubercle. 5th abdominal ventrite without bordering; with punctures 2.0–3.0 diameters apart.
Legs in both sexes simple.
Apical part of aedeagal tegmen equal to 0.25 of the rest of tegmen. Parameres narrowing towards apex. Clavae strait.
Paraproct longer then coxites. First sclerite wide and short; sclerites 3rd and 4th narrow and long. Bursa copulatrix without sclerite.
Distribution. This species has been collected in the following ecoregion of the East Africa (Tanzania): Southern Acacia -Commiphora bushlands and thickets (Fig. 12, 13).
