Sinolatindia petila gen. n. and sp. n. (Blattodea: Corydiidae: Latindiinae) is reported from Yunnan Province, China. Description, illustrations and a distribution map of the new taxon are provided. Comparisons with the type genus Latindia Stål, 1860 and the genus Homopteroidea Shelford, 1906 are given.

Latindiinae, a group of small sized Corydiidae cockroaches, is a poorly studied subfamily that superficially differs from the typical Corydiidae. Despite superficial differences, the diagnostic character of Corydiidae, “anal area of hind wing usually flat in resting position and simply folded over the anterior field” (
Recently, the cockroach collection of the Institute of Zoology, Chinese Academy of Science, Beijing (
Specimens studied and examined during this research are deposited in the following institutions:
Morphological terminology used in this paper mainly follows
The venation terms and their abbreviations in parentheses in this article are listed as below: subcosta (Sc), radius (R), radius anterior (RA), presutural vein, media (M), cubitus anterior (CuA), cubitus posterior (CuP), CuP in claval furrow (CuP in cfr), anal fold (afd), anal anterior (AA), and anal posterior (AP). The presutural vein is an important character in Homopteroidea, which may be a separated part of CuA, the area between it and the sutural margin totally hyaline, which is known as presutural zone, the terms “presutural vein” and “presutural zone” follow
The current Latindiinae only contains two genera (
The genital segments of the examined specimens were macerated in 10% NaOH and observed in glycerin jelly using a Motic® K400 stereomicroscope and a Leica® M205A stereomicroscope. All drawings were made with the aid of Adobe Photoshop® CS5, a Leica® M205A stereomicroscope and a Motic® K400 stereomicroscope. Photographs of the specimens were taken using a Canon® 50D plus a Canon® EF 100mm f/2.8L IS USM Macro lens combined with Helicon Focus® software; photos of other characters were taken using a Leica® M205A stereomicroscope. All photographs mentioned above were modified in Adobe Photoshop® CS5. The map was downloaded from www.d-maps.com and modified using Adobe Photoshop® CS5.

This subfamily is badly in need of revision. First, recent molecular phylogenetic studies (
纤蠊属
Sinolatindia petila sp. n. 素色纤蠊
Male. Small size, form elongate elliptical. Body flat, gracile, pubescent. Head transversely triangular, eyes wide apart, interocular space greater than the distance between antennal sockets, ocelli missing. Pronotum suboval, pubescent. Front femur short and robust, type C1 spination (Fig.
This genus is very close to the type genus Latindia Stål, 1860. We have examined the type specimen of Latindia maurella Stål, 1860 (Fig.
This genus may be confused with Homopteroidea, both of which have hyaline part of right tegmen and serrated tarsal claws, and all distributed in Oriental Region. Homopteroidea used to be determined as a member of Latindiidae (

China (Yunnan).
This generic epithet comes from the Latin word “Sino” and “Latindia”. “Sino” refers to China, “Latindia” in reference to the genus being similar to the Latin American genus Latindia.
This genus contains all the diagnostic characters of Latindiinae. It also quite resembles Latindia. Both of the genera hold in common the following characters: 1) body small, form elongate elliptical, very flat, pubescent; 2) head transversely triangle, eyes wide apart, ocelli absent (Fig.

Male. Body length 5.9–6.0 mm; overall length including tegmen 6.8–7.0 mm; pronotum length × width 1.2–1.3 × 1.5–1.6 mm.
Coloration: Body generally light brownish yellow, transparent (Fig.
Body very flat, narrow, well pubescent. Head: exposed dorsally, triangular, longer than its width, vertex nearly straight, face flat, eyes lateral, wide apart, surface with the individual facets convex, interocular space greater than the distance between antennal sockets, ocelli absent (Figs

The species epithet is from the Latin word “petilus” meaning thin and little in reference to its narrow and small body.
