Description

Male habitus in Fig. 1 . Although the male abdominal segments VII and VIII are not part of the genitalia, these are described here and illustrated because the morphology of the sclerites of these segments can be modified in different groups of Larentiinae ( Viidalepp 2011).

Male abdominal segments VII and VIII (Fig. 2 ). Segment VII mostly membranous; tergum a transverse stripe strongly posteriorly folded in the middle; sternum a transverse stripe; pleura with pair of coremata. Segment VIII mostly membranous; tergum an anterior transverse stripe with semicircular expansion on tips, connected by a short longitudinal stripe with a posterior rectangular transverse plate; sternum an anterior transverse stripe posteriorly curved in the middle, projected as a narrow longitudinal stripe posteriorly bifid, triangular expansion near tip of the anterior transverse stripe.

Male genitalia (Fig. 3 ). Uncus bifid with broad posterior concavity in the middle, truncate points slightly down-curved. Saccus with small rounded anterior projection. Subscaphium slightly sclerotised. Labides with lobe-like tip bearing setae. Manica heavily spinose. Juxta trapezoidal, ventral half of lateral margin broadly concave, ventral margin broadly concave. Valva elongated; costal sclerotised band not reaching apex; cucullus mostly membranous on distal half with abundant setae; sacculus broad, well-sclerotised; sacculus projection stout, apex almost reaches that of the distal margin of the cucullus, with a broader, dorsally projected basal process. Phallus cylindrical, anterior half straight, posterior half curved, with a small spine-like projection ventrally on posterior tip; vesica mostly membranous with a plate-like cornutus.

Female genitalia (Fig. 3 ). Papillae anales membranous, lobe-like, fused dorsally, posterior edge with setae on dorsal and lateral parts and elongated, flattened scales on ventral part. Apophyses posteriores rod-shaped, narrow, slightly longer than apophyses anteriores. Antrum well-sclerotised, flattened, ventrally curved in the middle, progressively straightening anteriorly. Ductus bursae membranous, about 2/3 length of the antrum. Corpus bursae membranous, spherical, with 5-7 stout spine-like signa arising ventrally from the anterior margin of a semicircular slightly sclerotised plate. Ductus seminalis arising near the posterior tip of ductus bursae.

Molecular analysis

Genetic distance of D. edmondsii (BOLD accession GEONC001-22) was 10.3-10.5% (K2P) with D. natalata and 11.0-11.5% with D. stellata , while the distance between the latter two was 6.2-7.1%. The alignment was suitable for phylogenetic analysis, as no evidence of stop codons was detected and the index of substitution saturation was smaller than the critical value (ISS <ISS.C; p <0.001) in the Xia test. The ML analysis (Fig. 4 ) clustered ( D. edmondsii ( D. natalata + D. stellata )) with high support. Although each genus had reasonable statistical support in the ML analysis, relationships between genera were not resolved.
