description: Scolytodes pelicipennis (Schedl)
(Figs 65, 67, 69)
Hexacolus pelicipennis Schedl, 1952: 356.
Material examined. Holotype, male: Costa Rica, Jimenez, Halbins. [Peninsula de] Osa, E. Reimoser leg [NHMW]. New record: Mexico, Oaxaca, Finca Montecarlo, Sta. Ma. Xadani, [GIS] 15.993, -96.104, 916m, 24-VI- 2009, ex Ficus sp., T.H. Atkinson THA-879. Host: trunk of Ficus sp, TH Atkinson, THA-793 [UTIC].
Diagnosis. Interstriae 10 sharply elevated to the level of metacoxa, protibiae with a small additional mesal tooth near tarsal insertion. Elytral striae increasingly impressed posteriorly, punctures increasingly larger. Distinguished from S. impressus Wood (Costa Rica) and S. striatulus Wood (Caribbean) by having only a few erect setae on odd-numbered interstriae only, and by the much larger strial punctures, and further from S. impressus by the more abundant pronotal asperities, and long abundant setae in the female frons.
Description female. Length 1.4¯ 1.6 mm, 2.2¯2.3 × longer than wide; colour dark reddish brown. Head. Eyes entire, separated above by 2.6¯2.8 × their width. Frons flattened, with a central impunctate area surrounded by long golden setae, progressively shorter towards the impunctate area. Antennal club with two oblique sutures marked by setae. Funiculus 6-segmented. Pronotum shiny, large punctures on posterior fourth separated by less than half their diameter, replaced on anterior three-fourth by coarse asperities, forming a low serrated ridge on anterior margin. Vestiture consisting of 8 erect setae (4–2–2) and shorter semi-recumbent setae in area with asperities. Elytra shiny, striae strongly and progressively impressed posteriorly, punctures large and deep, subconfluent; interstriae as wide as striae, punctures small, in rows. Vestiture consisting of scattered long spatulate setae on odd-numbered interstriae, with short fine setae on each declivital interstriae. Legs. Procoxae separated by 0.3¯0.4 × and mesocoxae 0.7¯0.8 × the width of one procoxa. Protibiae with distal tooth 1 slightly larger than 2, with 4 additional granules along the lateral edge towards base; protibial mucro short, curved posteriorly. Meso- and metatibiae with 6 and 5 lateral, socketed teeth on distal half. Ventral vestiture. Setae on metasternum and metanepisternum mainly simple, bifid close to anterior margin.
Male. Similar to females except slightly smaller (1.3¯ 1.5 mm), and the frons is convex, strongly reticulate and punctured, with fine short setae near epistoma.
Biology and distribution. Previously known only from a single male specimen from the west coast of Costa Rica. This is the first record from Mexico and the first of a female. Specimens were collected under bark of a Ficus tree.
