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 9: Mengenilla moldrzyki sp. n. ♀, details of head A left antenna, ventral view B Sensilla placodea on antennomere 4, lateral view C Mouthparts, ventral view D Left maxilla, mesal view E Left maxilla, ventral view F Left maxilla, lateral view; mfs, mouthfied sclerite; mx, maxilla; mxp, maxillary palp; os, mouth opening; pc, pedicellus; sc, scapus; SEM micrographs.

Mentions: Head capsule (Figs 7–9, 10A–10C): uniformly tan, with the exception of articulatory membranes of antenna and membranised ventral head areas. Relatively small, distinctly broader than long, and cuneiform in lateral aspect; orthognathous, with the posterior part distinctly retracted into the prothorax; laterocervicalia absent; dorsal side smooth, without vestiture of microtrichia; short setae present on anterior clypeal region, few setae present above antennal insertion and area posterior to compound eyes; ocelli absent; compound eye small, composed of 11–12 large, equally sized and closely adjacent ommatidia; microtrichia between ommatidia absent; central part of compound eye grey, peripheral ommatidia tan; circumocular ridge slightly darker; frontal impression on dorsal side of head absent; ventral side of head closed by membranised reduced labium and possibly cervical membrane; mouthfied sclerite small, oval, reaching posterior margin of maxilla; mouth opening transverse, oval.
