description: Family Heterolatzeliidae Verhoeff, 1897
Type genus: Heterolatzelia Verhoeff, 1897.
Type species. Heterolatzelia nivalis Verhoeff, 1897.
Diagnosis. A family in the superfamily Brannerioidea. Includes species with 29 pleurotegites + telson in adults. Lateral keels relatively small, rounded or dorsally flattened. Head with ocelli. Gnathochilarium with promentum. Leg-pairs 3–7 with tarsal papillae, without any additional processes. Leg-pairs 10 and 11 of adult males with coxal glands and without coxal processes. Anterior gonopods without flagella or cheirites, with straight or claw-like angiocoxites, simple colpocoxites, and comb-like posterior processes. Posterior gonopods with prominent wide ladle-like coxites, with or without apical setulose part.
Massarilatzelia Makarov & Ra đ a, new genus
Type species. Massarilatzelia dugopoljica Makarov & Rađa, new species
Etymology. The new genus is named after Massarum, the Latin name for the Mt. Mosor.
Description. Adults with 29 pleurotergites + telson. Body length 21.1– 15.1 mm. Lateral keels small, with flattened dorsal side, disappearing on somites XXVIII and XXIX. Macrochaetae almost in a straight line; on all somites length and shape of macrochaetae are identical. Frontal side of head in adult male flattened, in females concave. Head with ocelli arranged in 4 or 5 rows. Antennomeres III–VI with one, four, one, and four long sensitive setae, respectively. Leg pairs III–VII with tarsal papillae.
Gonopods: Anterior gonopods with massive angiocoxites, claw-like, curved caudally; reduced subquadrangular or ovoid colpocoxites and comb-like caudal processes. Posterior gonopods with prominent coxite and ovoid or subovoid setulose apical part.
Vulvae: Bursae slightly flattened dorsally, tuberculated and covered with setae only on lateral side. Operculum on both sides with setal field.
Distribution. Middle Dalmatia, Croatia; troglophilic and possibly endemic taxon.
Remarks. The new genus clearly differs from the representatives of the genus Heterolatzelia in the presence of massive claw-like angiocoxites, considerably shorter colpocoxites, and in the distribution of the pleurotergal macrochaetae almost in line.
Massarilatzelia dugopoljica Makarov and Ra đ a, new species Figs. 2–20; 26–27
Material examined. Holotype male, allotype female, paratype male, and paratype juvenile, from the Kraljeva Peċ Cave (= Baliċa Špilja) (Fig. 1), Baliċi, village Dugopolje, Mt. Mosor, near Split, Dalmatia, Croatia; collected on 22.viii 1981 by T. Rađa (NHMSC 616); paratype female, and 12 paratype juveniles, same locality; collected on iv. 1980 without collectors name (IZB 1210–1223).
Etymology. The species name is given after the locality of the new form, the village of Dugopolje.
Description. Body with 29 pleurotegites + telson (adults). Dorsal side of metazonites brownish, prozonites and ventral side of metazonites yellowish (Figs. 26–27). Body length 15.1 mm (holotype male), and 21.1 mm (allotype female). Vertical diameter of the largest pleurotergites 0.97 mm (holotype male), and 1.3 mm (allotype female).
Head: With 4–5 rows of 20–22 ocellae, occipital axial suture clear and densely setose. Labrum with 10–12 labral and 4 supralabral setae. Gnathochilarium: promentum triangular; stipites each with 5–6 long apical and medial setae, and 14–15 basal microsetae. Lingual plates with one row of 5 setae.
Antennal length 2.3 mm (holotype male), and 2.5 mm (allotype female). Length of antennomeres I–VII (holotype male and allotype female): 0.15–0.17 mm (I); 0.27–0.35 mm (II); 0.59–0.66 mm (III); 0.17–0.32 mm (IV); 0.54–0.62 mm (V); 0.24–0.26 mm (VI); and 0.20–0.22 mm (VII). Length/breadth ratios of antennomeres I–VII: 1.2–1.36 (I); 2.45–2.9 (II); 5.9–6.0 (III); 1.7–3.2 (IV); 3.8–5.63 (V); 1,3–2.36 (VI); and 1.3–2 (VII). Antennomeres III, IV, and VI with one, four, and four long sensitive setae, respectively. Antennomeres V with one long subapical sensitive seta, and apical ring of slightly shorter setae.
Collum narrower than head, with six macrochaetae.
Pleurotergites: Lateral keels of metazonites relatively small on anterior and median somites (Fig. 19), disappearing on somites XXVIII and XXIX. In width: collum <II <III <IV <V <VI <VII <VIII <IX = X–XII <XIII =XIV–XVIII> XIX> XX> XXI = XXII–XXIV> XXV> XXVI> XXVII> XXVIII> XXIX. Macrochaetae short; maximal length of macrochaetae on mid-body somites 0.14 mm. Macrochaetal index CIX (15), i.e., (distance between exterior and median macrochaetae/distance between interior and median macrochaetae) = 1.61 (female) – 1.33 (male). Median index MIX (15), i.e., (distance between interior macrochaetae and axial suture/distance between interior and median macrochaetae) = 0.67 (female) – 0.86 (male). Macrochaetal angle between arm created by median and exterior macrochaetae and arm formed by median and interior macrochaetae, MA (15) ≈ 173o (female) – 176o (male).
Epiproct truncated caudally, with two typical spinnerets; each paraproct with three long marginal setae; hypoproct subquadrangular, with two long apical setae.
Legs elongated, 1.23–1.61 times as long as mid-body height. Leg-pairs 1 and 2 slightly reduced, with tarsal brushes ventrally (Figs. 2–3).
Male sexual characters. Frontal side of head in adult male flattened. Leg-pairs 3–7 not greatly enlarged and modified as in many chordeumatids. In the new species these legs are supplied with tarsal papillae and with all podomeres are more or less slightly bulging. Tarsus of leg 3 (Figs. 4–5) with 3–4 rows of claw-like accessory setae and two rows of papillae. Legs 4–6 (Figs. 6–8) with ventral side of coxae, basoventral and dorsal side of prefemora denticulate, and with rows of tarsal papillae. Leg 7 with slightly denticulate dorso-subapical margins of prefemora, and with one row of claw-like setae and row of papillae (Figs. 9–10). Leg 10 and 11 with both dorsal and ventral margins of prefemora denticulate, as well as all surfaces of coxa (leg 11) or only ventral side (leg 10) (Figs. 11–12); both leg pairs with coxal glands, and without any lobes or processes.
Anterior gonopods. The anterior gonopods with a single wide protective subquadrangular part, covering almost half the cephalic side on both gonopods; on both lateral sides this element is expanded into two narrower points (Fig. 13). Both sides of gonopods clearly separated and consist of three elements. Massive angiocoxites are dominant, with wide basal part, and distal claw-like process curved caudally (Figs. 13–14, 18). In holotype male, apical angiocoxites carry three small pointed processes and one sub-basal denticulated lamella (Figs. 13–14). In paratype male this part consists of one pointed claw-like process and a shorter narrower one; subapically with two or three small lobes (Fig. 18). Second element are colpocoxites, subquadrangular in holotype male (Figs. 13–14), but ovoid with denticulated mesal side in paratype male (Fig. 18). Third element is a comb-like process, fused basally with the angiocoxites (possibly also derived from coxa) (Figs. 14, 18).
Posterior gonopods. The posterior gonopods consist of coxite (Figs. 15–17) and ovoid or subovoid apical process. The later is fused with coxite on cephalic side, covered with numerous setae on dorsal side and functioning as protective part for elements of anterior gonopods.
Female sexual characters. Mesal side of bursae without setae; lateral side covered with tubercles and with subapical field with moderate long setae (Fig. 20). Operculum with two groups of 6-7 long apical setae.
