Pohl H, Niehuis O, Gloyna K, Misof B, Beutel RG - Zookeys (2012)

Bottom Line: Mengenilla moldrzykisp. n. is the third species of the genus with known females and female puparia.First instar larvae, endoparasitic larval stages, the male puparium and the host are unknown.The new species is also the first strepsipteran with a fully sequenced genome.

ABSTRACT
A new species of Mengenilla Hofeneder, 1910 (Strepsiptera, Mengenillidae) from southern Tunisia is described. Mengenilla moldrzykisp. n. can be distinguished from congeners by a slightly emarginated posterodorsal margin of the head, compound eyes with a light tan dorsal part, mandibles with a narrow distal part, and a v-shaped pronotum. With the description of Mengenilla moldrzykisp. n., eleven valid species of Mengenilla are currently recognised. Mengenilla moldrzykisp. n. is the third species of the genus with known females and female puparia. First instar larvae, endoparasitic larval stages, the male puparium and the host are unknown. The new species is also the first strepsipteran with a fully sequenced genome.

Figure 5: Mengenilla moldrzyki sp. n. ♂ with definitions of the measurements A Antenna, caudal view B Left maxilla, lateral view C Right mandible, medio caudal view D Penis, lateral and dorso caudal view E–G Pro-, meso-, metathoracic leg, ventral view; 6 total length of antenna, 7 length of flabellum antennomere three, 8 length of flabellum of antennomere four, 9 length of flabellum antennomere five, 10 length of antennomere six, 11 length of mandible, 12 width of mandible, 13 total length of maxilla including palp, 14 length of proximal part of maxilla (cardo+stipes), 15 length of maxillary palp, 32 length of mesocoxa, 33 length of mesotrochanterofemur, 34 length of mesotibia, 35–39 length of mesotarsi (proximal to distal), 40 length of metatrochanter, 41 length of metafemur, 48 length of penis.

Mentions: To assess intraspecific variation, 74 male specimens of Mengenilla moldrzyki sp. n. were prepared on slides and embedded in Euparal (Chroma, Münster, Germany). To avoid shrink-artefacts, specimens were dehydrated using increased steps of ethanol up to 96% prior to preparation, followed by several steps of Euparal Essenz in increasing concentration (diluted with 96% ethanol) up to 80% and then finally embedded in Euparal. An antenna, a maxilla, legs, the hind wing of one side, and the penis were prepared and each covered separately with a coverslip. Measurements of the 74 prepared males were performed using an Olympus SZ 40 stereomicroscope and an Olympus BX 50 microscope with a calibrated ocular micrometer. Measurements of the female and of the female puparium were performed using SEM micrographs and macro photographs. Definitions of the measurements are illustrated in figure 4 and in figure 5. Morphological features were illustrated using a 10×10 ocular grid on either an Olympus SZ 40 stereo microscope or an Olympus BX 50 microscope. Drawings of features of the females are based on SEM micrographs. The colouration of different body parts of the specimens are specified after the List of colours (Wikipedia).
