Contribution to the knowledge of the Carpenter Moths (Lepidoptera, Cossidae) of the Maputo Special Reserve in South Mozambique with description of two new species

Present paper contains the first comprehensive summary of the Cossidae of the Maputo Special Reserve (South Mozambique), including ten species. Two species are described as new to science: Afrikanetz smithi Yakovlev & László sp. n. and Brachylia maputo Yakovlev & László sp. n. Three species are reported from Mozambique for the first time. With 14 colour and 2 black and white figures.


Introduction
Cossidae is a family of Lepidoptera including over 1200 valid species (van Nieukerken et al. 2011;Yakovlev 2011). In the last decade, there has a significant progress been achieved concerning the study of African Cossidae. Numerous new genera and species have been described, and the fauna of several African countries has been revised resulting in publications on the Cossidae of Malawi, Zimbabwe, Zambia, Swaziland, South Africa, Namibia, Central African Republic, Gabon, Sierra Leone, Angola, Burundi and Rwanda (Yakovlev & Lenz 2013;Yakovlev & Murphy 2013;Yakovlev 2014;Mey 2015Mey , 2016Mey , 2017Yakovlev et al. 2018;Yakovlev et al. 2019a, b, c;Yakovlev & Witt 2019a, b).
The knowledge on the Cossidae of Mozambique has been rather incomplete until now. According to the Afromoths website (De Prins & De Prins 2020) there are altogether 11 species recorded from the country. The knowledge on the Lepidoptera of Mozambique has significantly been increased thanks to a recent joint research project of the African Natural History Research Trust (ANHRT), the Natural History Museum of Maputo (MHNM) and the National Administration of Conservation Areas (ANAC) aiming to

Material and methods
The Cossidae specimens were collected by various means of light trapping, applying light house illuminated by 125W Mercury vapor bulb and automatic bucket traps equipped with 8W actinic light tubes. The collected material is deposited in the collection of African Natural History Research Trust, Leominster (ANHRT) and the Natural History Museum of Maputo (MHNM). The genitalia were dissected and stained with Eosin red and mounted in Euparal on microscope slides applying standard methods of preparation (Lafontaine & Mikkola 1987). The adults were photographed using a Nikon D700 camera equipped with Nikkor AF-S Micro 105 mm lens. The genitalia preparations were photographed using a Tucsen H series digital microscope camera mounted on a Nikon SMZ1500 stereomicroscope.
Abbreviations    Yakovlev, 2009 (Type locality: Arabia, Jedda) by its much less sharply defined brown spot of the forewing discal area, shorter and thicker phallus, and by its less developed ribs on the inner surface of the valva.

Description.
Male. Length of forewing 15 mm. Antennae short, bipectinate, crest rami three times longer than antenna rod diameter. Tegulae and patagia grey. Forewing narrow, pale grey with thin blackish transverse lines in submarginal and postdiscal areas and a poorly visible brownish patch in discal area; basal area grey without pattern. Hind wing pale grey, with faint pattern of strokes in cubital area.
Male genitalia. Uncus long, robust, distally tapered, apically rounded; gnathos arms long, thick; gnathos compact, covered with tiny spines; valva relatively narrow, long, membranous in distal quarter with a pronounced ledge on costal margin; transitional area between sclerotized membranous part with three transverse ribs on inner surface of valva, the middle one of them more developed than the other two; transtilla process relatively short, medially curved, apically tapered, pointed; juxta robust, with relatively large, diverged lateral processes; saccus semicircular, medium sized, phallus short (somewhat shorter than valva), thick, slightly curved in medium third, with small spike ventrally, vesica aperture in dorso-apical position, equal to 1/3 of phallus in length, with two small spines on vesica aperture edge, vesica without cornuti.
Female unknown.
Etymology. The new species is named after Mr. Richard Smith (Leominster, U.K.), founder of the ANHRT, organizer of extensive entomological exploratory program in Subsaharan Africa. Diagnosis. The new species resembles externally B. terebroides, but differs from it by its much lighter coloration, longer uncus, more straight and narrower transtilla processes, and almost straight phallus that is strongly curved in B. terebroides.

Description.
Male. Length of forewing 14 mm. Antennae bipectinate, rather long, equal in length to 3/5 of fore wing costal margin, crest rami three times longer than antenna rod diameter. Tegulae pale brown. Head and abdomen densely covered with pale grey scales. Forewing wide, apically rounded, pale grey with thin blackish undulated transverse lines in submarginal, postdiscal and discal areas; pale brown spot in discal area blurred; fringe pale brownish grey, unicolorous. Hind wing pale grey with a more or less parallel series of poorly visible undulated thin greyish lines.
Male genitalia. Uncus robust, triangle, apically rounded, relatively short; gnathos arms thick, long; gnathos robust, densely covered with tiny spines; valva membranous distally with a small crest with pointed pronglike process on costal margin at the transition between the sclerotized and membranous areas of valva; transtilla process long, thin, medially curved, apically pointed; juxta robust, with large, widely diverged lateral processes; saccus semicircular, robust; phallus almost straight, somewhat shorter than length of valva, thick, apex obliquely cut, vesica aperture in dorso-apical position, equal to ¼ of phallus in length, vesica without cornuti. Female unknown.
