Description.

Body. Length 1.9–2.7 mm in male; 2.3–3 mm in females; 1.4–1.7 mm in juveniles. Epicuticle with microdenticles under optical microscope (Fig. 5 a View Figure 5 ) and dense microdenticles under scanning electron microscope (Fig. 5 b, c View Figure 5 ); body with smooth short clothing setae (Fig. 5 a-c View Figure 5 ).

Head. Antennae with 15–19 antennomeres in juveniles and adults, 0.53–0.47 shorter than length of the body in juveniles and 0.45– 0.31 in adults; central antennomeres as long as wide with one proximal whorl of bifurcated macrosetae and one distal whorl of smooth macrosetae and uneven short smooth setae; in addition to a single distal whorl of ≤ 4–6 gouge sensilla of 5–6 µm long (Fig. 4 a-d View Figure 4 ). Proximal antennomeres with typical trichobothria disposition and with small bacilliform sensillum on third antennomere in dorsal position, between b – c macrosetae. Plain frontal process with one anterior macrosetae, longer than clothing setae. Three macrosetae each with two or three barbs along each side of insertion line of antennomere with length ratios of a / i / p, 11 / 13 / 14, respectively, in holotype. Large suboval labial palps, each with small latero-external sensillum near two gard setae and five normal setae on anterior portion, ≤ 60 neuroglandular setae in medial and posterior positions.

Thorax. Thoracic macrosetae distribution: pronotum has 1 + 1 ma, 1 + 1 la, 1 + 1 lp macrosetae; mesonotum has 1 + 1 ma, 1 + 1 la macrosetae (Figs 5 a View Figure 5 , 6 a View Figure 6 ). All macrosetae longer than other setae with barbs in distal ½ – 3 / 4 marginal setae barbed and longer than clothing setae. Short legs, metathoracic legs reach border of fourth abdominal segment. Calcars with two or three long barbs in middle. Each tarsus with two separated ventral rows of slightly and thicker smooth setae among clothing setae. Three long smooth dorsal tarsal and one ventral setae. Subequal simple claws and with smooth lateral processes.

Abdomen. Distribution of abdominal macrosetae on tergites (Fig. 6 b View Figure 6 ) shows 1 + 1 la on V, 1 + 1 la, 1 + 1 lp on VI – VII; 3 + 3 lp on VIII and 5 + 5 lp on IX abdominal; la macrosetae with barbs in distal ½ – 1 / 3 and lp macrosetae bear barbs along distal 4 / 5. Urosternite I with 7 + 7 macrosetae; urosternites II to VII with 4 + 4 macrosetae; urosternite VIII with 1 + 1 macrosetae; urosternal macrosetae of bifurcated, tri or quadrifurcated. Stylus setae with smooth subapical setae, bifurcated ventromedial seta and with two long basal barbs on apical seta.

Secondary sex features. Female urosternite I with subcylindrical appendages, each bearing ≤ 12 glandular a 1 setae in apical field. Male urosternite I with subtrapezoidal appendages, each with apical field of ≤ 17 glandular a 1 setae; a continuous posterior field of ≤ about 100 g 1 glandular setae arranged in 1–3 rows. Two incomplete cerci with basal article plus five primary articles. Internal smooth macrosetae or with one distal barb in proximal articles and other macrosetae with four or five distal barbs; primary articles with up to three whorls of barbed macrosetae, and uneven short smooth setae.

Taxonomic affinities.

The distribution of urotergal macrosetae in Campodea (Dicampa) transylvanica Sendra , sp. nov. from the Romanian Carpathians matches that of Campodea (Dicampa) plagiaria Silvestri, 1932 from the Baetic and Riff mountains ( Silvestri 1932 b). However, Campodea (D.) transylvanica Sendra , sp. nov. differs from C. (D.) plagiaria in several taxonomic features: 15–19 antennomeres in Campodea (D.) transylvanica Sendra , sp. nov. instead of 26–28 antennomeres in soil populations of Campodea (D.) plagiaria ; sensillum on the third antennomere in tergal position in C. (D.) transylvanica Sendra , sp. nov. instead of ventral in C. (D.) plagiaria ; apical barbs on marginal notal setae in C. (D.) transylvanica Sendra , sp. nov. instead of thin pine marginal setae in C. (D.) plagiaria .

Etymology.

Named after Transylvania, a historical and cultural region in Central Europe that encompasses central Romania.

Habitat and distribution.

A soil-dwelling species that is found in mixed forests in Zarand and Făgăraș mountains. In two localities it co-occurs with Campodea (Dicampa) propinqua Silvestri, 1932 .
