(Figs 1–2, 5, 7–10)
Type material. HOLOTYPE: ♁, ‘[DEMOCRATIC REPUBLIC OF THE] CONGO, [South] Kivu, S of Kahuzi Mt., Biega-Kahuzi N.P., 2200 m, III. 1993 [collector not mentioned]’ (NMPC, ex. coll. R. Kundrata).
Description of holotype. Body (Figs 1–2) 2.80 times longer than width at humeri. Body brown, antennomeres I–II, dorsal surface of head, basal part of elytra, and ventral parts lighter, mouthparts, legs and apex of abdomen yellowish brown; body surface covered with yellow pubescence.
Head (Fig. 7) including eyes 0.80 times as wide as pronotum; surface rather flat, 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, prominent, their frontal distance 1.35 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, slightly wider than long, palpomere IV elongate, fusiform, apically flattened, obliquely narrowed. Antenna (Fig. 5) with 11 antennomeres; 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 (Figs 1, 7) slightly convex, transverse, widest at posterior angles, 1.85 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 and longer at posterior angles. Prosternum strongly transverse, with frontal margin almost straight, oriented ventrally, with long semi-erect setae; prosternal process reduced to relatively 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. 1) subparallel-sided, 0.70 times as long as body, combined twice as long as wide, basally wrinkled, with indistinct striae, very sparsely punctate, covered with moderately long, semi-erect pubescence.
Legs moderately long, slender, slightly compressed, with sparse, long, semi-erect setae; 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 about 1.4 times as long as wide, widely rounded apically. Sternite IX (Fig. 8) elongate, about twice as long as wide, emarginate basally, apex narrowed, with sparse short setae.
Aedeagus (Figs 9–10) 1.80 times as long as wide; median lobe narrow, short, only slightly surpassing apices of parameres, about as long as phallobase, moderately curved in lateral view, basally with two short struts, dorsally with short subapical hook; parameres elongate, with almost straight sides, subacute apically, sparsely setose; phallobase robust, slightly longer than wide, u-shaped, basally narrowed and produced dorsally.
Female and immature stages unknown.
Measurements. BL 3.35 mm, WHum 1.20 mm, EL 2.40 mm, WHe 0.80 mm, PL 0.55 mm, PW 1.05 mm, Edist 0.45 mm, Ediam 0.35 mm.
Differential diagnosis. Lolosia gajduskovae sp. nov. differs from L. transversalis in larger body (3.35 mm; 2.10 mm in L. transversalis), darker brown body coloration (Figs 1–2; yellowish to light brown in L. transversalis), apex of median lobe only slightly surpassing apices of parameres (distinctly surpassing apices of parameres in L. transversalis), and relatively wide parameres (Figs 9–10; relatively slender and more elongate in L. transversalis). Lolosia smetkovae sp. nov. differs in having head and pronotum distinctly darker than elytra (lighter than most of elytra in L. gajduskovae; Figs 1–4), sternite IX gradually rounded apically (narrowed apically in L. gajduskovae; Figs 8, 12), paramere laterally rounded (almost straight in L. gajduskovae), and phallobase v-shaped (u-shaped in L. gajduskovae; Figs 9, 13).
Etymology. This species is named in honor of Miss Leona Gajdušková (Mosty u Jablunkova, Czech Republic).
Distribution. The Democratic Republic of the Congo: South Kivu Province.
