Semiclivina (Uroclivina) schmidi sp. n. Fig. 4b89

Specific epithet.

Latinized noun, genitive case, an eponym based on the surname of the collector of this species, my colleague and friend Herbert Schmid.

Recognition.

a typical Uroclivina - species with base of elytra with a keel at the end of intervals 3 to 5; elytral stria 1 extended parallel to suture, not joined to suture near base; abdominal sterna with very fine, transverse microreticulation and a group of shallow punctures at sides; median lobe of aedeagus flattened, blade-like.

Description.

Color: both individuals are immature and lighter reddish-brown; it is most likely that mature individuals are unicolorous dark brown to piceous, with annexes lighter, reddish-brown. Microsculpture: frons, pronotum and elytra with a fine, sometimes barely visible, more or less isodiametric microsculpture, but surface glossy. Head: 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; divided from frons by a transverse furrow; longitudinal sulci broad, surface microreticulate, bearing a seta at basal level of clypeus on each side; frons glossy, but with fine, sometimes indistinct microreticulation, with a very shallow central foveola; above supraorbital setae with a broad ridge, medially bordering a small longitudinal groove, in this area the microreticulation more distinct; neck finely punctate, interrupted at middle in the holotype, not interrupted in the paratype; posterior margin of eye with the characteristic tubercle. Prothorax: convex, disc somewhat flattened, about as wide as long (0.97x, see Table 2); surface glossy, but with fine microreticulation, fine transverse wrinkles in the basal two thirds, declivity at base with transverse wrinkles more dense and more distinctly shagreened; anterior angles markedly produced forward, mediad with a sharp and narrow incision, which corresponds to the postorbital tubercle. Elytra: about twice long as wide (range: 1.94 × - 1.98 ×, see Table 2); subparallel, convex, broadest in the apical third, glossy, with very fine, barely visible microreticulation; elytral striae distinctly engraved from base to apex, with gross punctures at base which become finer towards apex; 6th to 8th interval narrowed at base and elevated as a keel; first stria elytral extended more or less parallel to suture, not bent inward toward suture at base; a fine, scutellar keel extended from the basal tubercle at the end of the second interval obliquely posteriorly to suture. Legs: fore-tibia 4 dentate, the proximal dentiform projection very small, triangular, upper surface indistinctly sulcate; profemur with a sharp denticle at the proximal end of the outer edge; mesotibia with a small distal spur on the upper edge, which is about two times longer than wide.

Abdominal sterna : abdominal sterna IV to VII very finely transversally microreticulate, mesh pattern isodiametric at sides, abdominal sternum VII with a group of about 10 fine and shallow punctures on each side, and with 2 pairs of marginal setae in both sexes, relatively close together. Male genitalia (Fig. 9 a-c): median lobe blade-like flattened, apex spatulate; parameres long and slender, left one about twice as broad as the right one, with 7 setae at apical margin, right one with a apical fringe of about 10 setae. Female genitalia, ovipositor : stylus long, slender, bent inwards, apex acute (Fig. 9 d-e).
