Semiclivina (Uroclivina) bergeri sp. n. Fig. 34a56

Clivina (Semiclivina) marquardti Van Emden 1949: 861-863, museum label name

Specific epithet.

Latinized noun, genitive case, an eponym based on the surname of my friend and partner, Helmut Berger jun., who organizes and joins me in my entomological excursions all over the world.

Recognition.

A typical Uroclivina - species with basal border of elytra without a keel, elytral stria 1 in the basal part closely joining suture; abdominal sterna without punctuation, but with distinct microsculpture, median lobe of aedeagus flattened, blade-like.

Description.

Color: mature individuals are unicolorous dark brown to piceous, with annexes lighter, reddish-brown, immature ones are all variations lighter up to light yellow-brown, usually all stages are met within a population. Microsculpture: glossy, pronotum and elytra with a fine, sometimes barely visible, more or less isodiametric microsculpture, but still glossy Head (Fig. 3): middle part of clypeus more produced than lateral wings, anterior margin slightly concave, bordered, wings unbordered; preocular area finely bordered; upper surface of clypeus glossy without microsculpture, except microscopic fine punctures; clypeus divided from frons by a transverse furrow; longitudinal sulci broad, ground microreticulate, bearing a seta at basal level of clypeus on each side; frons glossy, with a very shallow central foveola; above supraorbital setae with a broad ridge, medially bordering a small longitudinal reticulate groove; neck finely punctuate, interrupted at middle; posterior margin of eye with the characteristic tubercle. Pronotum: convex, disc somewhat flattened, about as wide as long (range 0,88x to 1,04x, see Table 1); surface glossy, but with fine microreticulation, fine transverse wrinkles in the basal two thirds, declivity at base with transverse wrinkles more dense and distinctly shagreened; anterior angles strongly produced forward, mediad with a sharp and narrow incision, which corresponds to the postorbital tubercle. Elytra: about twice long as wide (range: 1.93 × - 2.11 ×, see Table 1); subparallel, convex at sides, disc somewhat flattened, glossy, with very fine microreticulation; elytral striae distinctly engraved from base to apex, with gross punctures at base which become finer towards apex; 7th and 8th interval narrowed at base and sometimes elevated to a keel; first elytral stria bending inwards towards suture at base, from the second sixt h onwards it continues parallel to suture up to the apex. Legs: fore-tibia 4 dentate, the proximal one very small, triangular, upper surface distinctly sulcate; mesotibia with a small distal spur on the upper edge, which is about two times longer than wide. Abdominal sterna (Fig. 4a): IV to VI finely transversally microreticulate, isodiametric at sides, VII completely isodiametrically microsculptured, with 2 pairs of marginal setae in both sexes, relatively close together. Male genitalia (Fig. 6a-d): median lobe blade-like flattened, apex spatulate; parameres long and slender, left one about twice as broad as the right one, with 2 setae at apex, right one with an apical fringe of about 10 setae. Female genitalia: stylus tall, slender, bent inwards, apex acute, lateral with one big seta, ventral with 4 smaller setae (Fig. 6e-f).

Measurements.
