Lolosia smetkovae sp. nov.

( Figs 3–4, 6, 11–14 )

Type material. HOLOTYPE: ♁, ‘ CENTRAL AFRICAN REPUBLIC, Bamingui-Bangoran prov. [Prefecture], 75 km SSW Ndele , 450 m, 08.– 12.7.2011, A. Kudrna JR. lgt.’ ( NMPC).

Description of holotype. Body ( Figs 3–4 ) 2.70 times longer than width at humeri. Head, thorax and abdomen dark brown, antennomeres III–XI lighter, antennomeres I–II and elytra light brown, mouthparts and legs yellowish brown; body surface covered with yellow pubescence.

Head ( Fig. 11 ) including eyes 0.80 times as wide as pronotum; surface slightly convex, smooth, slightly depressed medially, sparsely and shallowly punctured, covered with sparse, long semi-erect pubescence; fronto-clypeal region wider than long, its surface rough. Eyes large, their frontal distance 1.30 times eye diameter. Labrum transverse, short, with frontal margin slightly concave. Mandible moderately long, bidentate, with robust tooth located in middle part of incisor, basally with long setae, apically shiny. Maxillary palpus slender, palpomere III short, wider than long, palpomere IV elongate, fusiform, apically subacute. Antenna ( Fig. 6 ) with 11 antennomeres, serrate; scape robust, widened apically, pedicel short, small, antennomeres III–X serrate, their surface rugose, antennomere III long, about twice as long as antennomere II, antennomeres IV–X slightly shorter than antennomere III, subequal in length, apical antennomere simple, longest, about 1.3 times longer than penultimate antennomere; all antennomeres covered with moderately dense semi-erect pubescence.

Pronotum ( Fig. 11 ) slightly convex, transverse, widest at posterior angles, 1.90 times wider than length at midline. Anterior margin almost straight, lateral margins diverging posteriorly, sinuate from lateral view, posterior margin widely convex, slightly emarginate medially. Anterior angles inconspicuous; posterior angles obtuse, with wrinkled surface. Disc with distinct sinuate sublateral carinae almost reaching anterior margin, and transverse carina near posterior margin. Lateral carina incomplete anteriorly. Surface of disc smooth, very sparsely covered with small shallow punctures, with sparse semi-erect pubescence, denser at posterior angles. Prosternum strongly transverse, with frontal margin widely convex, oriented ventrally, with long semi-erect setae; prosternal process reduced to very short, slender, subparallel-sided spine, pointed apically.

Scutellar shield flat, triangular, smooth, about as long as wide, narrowly rounded posteriorly. Mesoventrite v-shaped, with frontal margin widely concave; mesoventral cavity shallow, with poorly defined walls. Elytra ( Fig. 3 ) subparallel-sided, 0.70 times as long as body, combined 1.90 times as long as wide, basally wrinkled, indistinctly striate, sparsely punctate, covered with moderately long, semi-erect pubescence.

Legs moderately long, slender, slightly compressed, with sparse, long, semi-erect setae; tarsi relatively long, tarsomeres I–II subequal in length, tarsomere III slightly shorter but longer than tarsomere IV; tarsomere IV shortest, extended ventrally, apical tarsomere slender, elongate; claws simple, slender, slightly curved, each with long seta basally.

Abdomen with ventrites sparsely and finely punctate, covered with sparse semi-erect pubescence. Tergites IX and X weakly connected by membrane; tergite IX transverse, tergite X slightly longer than wide, rounded apically. Sternite IX ( Fig. 12 ) elongate, about twice as long as wide, notched basally, apex rounded, with sparse short setae.

Aedeagus ( Figs 13–14 ) 1.80 times as long as wide; median lobe stout, short, only slightly surpassing apices of parameres, slightly shorter than phallobase, moderately curved in lateral view, basally with two short struts, dorsally with short subapical hook; parameres elongate, with rounded sides, subacute apically, sparsely setose; phallobase robust, slightly longer than wide, v-shaped, basally narrowed and produced dorsally.

Female and immature stages unknown.

Measurements. BL 3.05 mm, WHum 1.10 mm, EL 2.10 mm, WHe 0.80 mm, PL 0.50 mm, PW 0.95 mm, Edist 0.40 mm, Ediam 0.30 mm.

Differential diagnosis. Lolosia smetkovae sp. nov. is similar to L. gajduskovae sp. nov. in habitus, body size, dark body coloration, apex of median lobe only slightly surpassing apices of parameres, and relatively wide parameres. These species differ in the coloration of head and pronotum (distinctly darker than elytra in L. smetkovae , lighter than most of elytra in L. gajduskovae ; Figs 1–4 ), the apical portion of sternite IX (gradually rounded in L. smetkovae , narrowed in L. gajduskovae ; Figs 8, 12 ), the lateral side of paramere (rounded in L. smetkovae , almost straight in L. gajduskovae ), and the shape of phallobase (v-shaped in L. smetkovae , u-shaped in L. gajduskovae ; Figs 9, 13 ).

Etymology. This species is named in honor of Miss Milada Smetková (Praha, Czech Republic).

Distribution. Central African Republic.
