| Abstract |
| The systematics of the mite family Laelapidae is characterized by considerable complexity and numerous unresolved taxonomic issues. Many species within Laelapidae were originally described in the late 19th and early 20th centuries, often based on limited morphological characters and without the aid of modern microscopy or imaging techniques. In the present study, the type materials of two species of Hypoaspisella Bernhard, 1962 namely H. procerus (Karg, 1965) and H. lubricoides (Karg, 1971) were re-examined at the Museum für Naturkunde Berlin, Germany. Based on a comparison between H. procerus (based on female slides ZMB Nr. 41110, 41111, 41096), and H. asperatus (Berlese, 1904), contrary to previous idea, these two species are not synonyms and could be considered as valid and separate species. In H. procerus dorsal shield has 39 pairs of setaceous setae, none of them reach to the base of the next setae in the series, the distance between J3-J4 approximately quadruple of the J3 length. Dorsal shield bears five Jx setae between J2-J4. Sternal shield with reticulation in most surface except in posterior and posterolateral margins, iv1 slit-like horizontally and iv2 slit-like longitudinally slightly behind st2, epigynal and anal shields reticulated throughout. Deutosternal rows exhibit 2-4 teeth per row, h3 is the longest hypostomal setae. In H. lubricoides [based on female slides ZMB Nr. 40637 (holotype), 40640, and 40641) dorsal shield characterized with ornamentation which is more prominent in opisthonotal region, the shield bears 38 pairs of setaceous setae, podonotal lacking r5, the distance between J3-J4 exceeds twice the length of the J3 setae. Dorsal shield possesses two Jx setae adjacent to J2-J2, and between J3-J4. The reticulated presternal plates conncted with each other with striae, sternal shield with reticulation in most surface except in posterior and posterolateral margins, iv1 slit-like horizontally and iv2 poroid shaped, epigynal and anal shields reticulated throughout. Legs chaetotaxy normal for laelapid mites, pd3 on femur I slightly thicker than the other setae on the segment, ventral setae on legs II-IV slightly thicker than other setae on the segments. The lengths of hypostomal setae h1 and h3 exceed twice of the h2 lentgh. Deutosternal rows exhibit 4-10 teeth per row, the maximum and minimum teeth observed in upper and lower-most rows respectively. Despite extensive morphological examinations and even studies of type specimens, future molecular approaches, including genomic analysis, may provide a more reliable or complementary structure. |
